By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes a while. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Type `make install' to install the programs and any data files and + documentation. + + 4. You can remove the program binaries and object files from the + source code directory by typing `make clean'. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. + diff --git a/kernel/driver/Makefile b/kernel/driver/Makefile new file mode 100644 index 00000000..f36be86c --- /dev/null +++ b/kernel/driver/Makefile @@ -0,0 +1,41 @@ +MDIR = extra + +KDIR ?= $(shell sh find_kernel_headers) + +obj-m += pptp.o +#obj-m += ppp_generic_smp.o + +CURRENT = $(shell uname -r) + + +ifndef MAKING_MODULES +all: kernel_headers + make -C $(KDIR) SUBDIRS=$(PWD) modules +endif + +ifneq (,$(findstring 2.4.,$(CURRENT))) +install: + @if test ! -d /lib/modules/$(CURRENT)/extra; then \ + mkdir /lib/modules/$(CURRENT)/extra; \ + fi; \ + cp -v $(TARGET).o /lib/modules/$(CURRENT)/extra/$(TARGET).o && /sbin/depmod -a +else +install: + make -C $(KDIR) M=$(PWD) modules_install +endif + +kernel_headers: + @if test -z "$(KDIR)"; then \ + echo "kernel headers not found"; \ + exit 1; \ + else \ + echo "using \"$(KDIR)\" kernel headers"; \ + fi + + +clean: + -rm -f *.o *.ko .*.cmd .*.flags *.mod.c + +ifneq (,$(findstring 2.4.,$(CURRENT))) +include $(KDIR)/Rules.make +endif diff --git a/kernel/driver/NEWS b/kernel/driver/NEWS new file mode 100644 index 00000000..e69de29b --- /dev/null +++ b/kernel/driver/NEWS diff --git a/kernel/driver/README b/kernel/driver/README new file mode 100644 index 00000000..e69de29b --- /dev/null +++ b/kernel/driver/README diff --git a/kernel/driver/TODO b/kernel/driver/TODO new file mode 100644 index 00000000..e69de29b --- /dev/null +++ b/kernel/driver/TODO diff --git a/kernel/driver/find_kernel_headers b/kernel/driver/find_kernel_headers new file mode 100755 index 00000000..3d0e505e --- /dev/null +++ b/kernel/driver/find_kernel_headers @@ -0,0 +1,21 @@ +#!/bin/bash + +if test -n "${KDIR}"; then + if test -f ${KDIR}/include/linux/version.h; then + echo ${KDIR} + exit 0 + else + exit 1 + fi +else + if test -f /usr/src/linux/include/linux/version.h; then + echo /usr/src/linux + exit 0 + elif test -f /lib/modules/`uname -r`/build/include/linux/version.h; then + echo /lib/modules/`uname -r`/build + exit 0 + else + exit 1 + fi +fi +

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

--- /dev/null +++ b/pppd_plugin/INSTALL @@ -0,0 +1,167 @@ +Basic Installation +================== + + These are generic installation instructions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes a while. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Type `make install' to install the programs and any data files and + documentation. + + 4. You can remove the program binaries and object files from the + source code directory by typing `make clean'. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. + diff --git a/pppd_plugin/Makefile.am b/pppd_plugin/Makefile.am new file mode 100644 index 00000000..02520f20 --- /dev/null +++ b/pppd_plugin/Makefile.am @@ -0,0 +1,5 @@ +# not a GNU package.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) 19yy <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

Edit the file plugins/patchlevel.h +accordingly. + +-- + +Basic Installation +================== + + These are generic installation instructions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. diff --git a/pptpd-1.3.3/Makefile.am b/pptpd-1.3.3/Makefile.am new file mode 100644 index 00000000..91fd76c4 --- /dev/null +++ b/pptpd-1.3.3/Makefile.am @@ -0,0 +1,102 @@ +# We have our own, simpler dependencies stuff in 'reconf' +AUTOMAKE_OPTIONS = no-dependencies foreign + +@SET_MAKE@ + +export LIBDIR=$(libdir)/pptpd +INCLUDES = -I. +## Change this if you don't have gcc +## -pedantic removed for now (OpenBSD header files). +## -Werror removed for now (getopt stuff on OSF/1 throws a +## warning with -Wmissing-prototypes). +## -Wmissing-prototypes removed (eg, Linux 2.2.6 headers +## aren't up to it). +CFLAGS = -O2 -fno-builtin -Wall -DSBINDIR='"$(sbindir)"' -I$(kernel_headers) +#CFLAGS = -O2 -fno-builtin -Wall -ansi -DSBINDIR='"$(sbindir)"' +#CFLAGS = -O2 -fno-builtin -Wall -ansi -pedantic -Wmissing-prototypes -Werror -DSBINDIR='"$(sbindir)"' + +man_MANS = pptpd.8 pptpd.conf.5 + +EXTRA_DIST = \ +html README* ChangeLog NEWS* TODO $(man_MANS) \ +samples/chap-secrets samples/options.pptpd samples/pptpd.conf \ +Makefile.uClinux config.embed.h version reconf \ +tools/pptp-portslave tools/vpnstats tools/vpnstats.pl tools/vpnuser \ +pptpd.init pptpd.spec makepackage \ +plugins/Makefile plugins/*.h plugins/*.c \ +debian/README.debian debian/changelog debian/conffiles debian/config \ +debian/control debian/copyright debian/dirs debian/docs \ +debian/examples debian/pptpd-options debian/pptpd.conf \ +debian/pptpd.init debian/pptpdconfig.pl debian/rules debian/templates \ +debian/po/POTFILES.in debian/po/fr.po debian/po/pt_BR.po \ +debian/po/templates.pot + +EXTRA_PROGRAMS = +sbin_PROGRAMS = pptpd pptpctrl bcrelay + +# Header files are only used to determine what to put in a distribution, not +# for dependencies, so just attribute them all to pptpd. + +pptpd_SOURCES = \ + pptpd.c configfile.c pptpmanager.c compat.c inststr.c getopt.c getopt1.c \ + compat.h configfile.h ctrlpacket.h defaults.h inststr.h our_getopt.h \ + our_syslog.h pptpdefs.h pptpmanager.h + +pptpctrl_SOURCES = \ + pptpctrl.c ctrlpacket.c inststr.c compat.c + +pptpd_LDADD = $(XTRALIBS_MGR) + +pptpctrl_LDADD = $(XTRALIBS_CTRL) + +bcrelay_SOURCES = bcrelay.c defaults.h our_syslog.h our_getopt.h + +subdirs = plugins + +all-local: + for d in $(subdirs);

It works as follows. + +When a connection occurs, pptpd launches pppd with two additional +options. The first option directs pppd to load the pptpd-logwtmp.so +plugin. The second option is the IP address of the client. + + "plugin /usr/lib/pptpd/pptpd-logwtmp.so" + "pptpd-original-ip 10.0.0.1" + +The plugin defines the pptpd-original-ip option so that pppd will +accept it. + +If the plugin fails to load, pppd will fail in the usual manner. Such +a failure will usually be related to a missing file in /usr/lib/pptpd. + +The plugin asks pppd to notify it when IP comes up or goes down. + +When IP comes up, the plugin's ip_up() function executes, calling +logwtmp() to mark the user as logged in. Once this has happened, +commands like "who" will show the user. The tty will be set to the +PPP interface name. + +When IP goes down, the plugin's ip_down() function executes, removing +the entry from wtmp. Note that a "kill -9" on the pppd will result in +a user appearing to remain logged in. Don't use "kill -9", use an +ordinary kill. + +If pppd debug mode is enabled, the plugin announces it's version when +loaded, and reports the parameters it is handing over to the logwtmp +call.

In an in-source build this is usually +# harmless because $srcdir is `.', but things will broke when you +# start a VPATH build or use an absolute $srcdir. +# +# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, +# iff we strip the leading $srcdir from $ac_aux_dir. That would be: +# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` +# and then we would define $MISSING as +# MISSING="\${SHELL} $am_aux_dir/missing" +# This will work as long as MISSING is not called from configure, because +# unfortunately $(top_srcdir) has no meaning in configure. +# However there are other variables, like CC, which are often used in +# configure, and could therefore not use this "fixed" $ac_aux_dir. +# +# Another solution, used here, is to always expand $ac_aux_dir to an +# absolute PATH.

This packet repeater (currently designed for +// udp packets) will listen for broadcast packets. +// When it receives the packets, it will then re-broadcast the packet. +// +// Written by TheyCallMeLuc(at)yahoo.com.au +// I accept no responsiblity for the function of this program if you +// choose to use it. +// Modified for Poptop by Richard de Vroede <r.devroede@linvision.com> +// Ditto on the no responsibility. +// +// Rewritten by Norbert van Bolhuis <norbert@vanbolhuis.demon.nl> bcrelay (v1.0+) +// now supports/does: +// 1) Relaying from PPP (VPN tunnel) interfaces, hereby creating a virtual +// LAN (w.r.t. UDP broadcasts) for VPN clients and ethernet PCs +// belonging/matching the subnet portion of the VPN IP addresses. +// So now broadcasting to/from all systems of the VPN has been implemented. +// Note that bcrelay v0.5 only relayed from LAN to VPN clients. +// It doesn't matter whether the systems on the VPN are on the LAN of the +// VPN server or have a VPN/PPTP connection (over the internet) to the VPN +// server. Broadcasts will always be relayed to/from all given interfaces. And +// as long as the subnet portion of the IP addresses of the systems on the VPN +// matches, the VPN server will be able to route properly. This means all +// networking applications/games that rely on a UDP broadcast from one or +// more PPP (VPN tunnel) interfaces will now see eachother and work over +// the VPN. +// Note that it depends on the networking application/game and whoever +// acts as application/game server/host who is sending (UPD) broadcasts +// and who is listening. +// 2) UDP broadcasts received on a PPP interface (VPN tunnel) sometimes +// don't carry the VPN IP address which pptpd provisioned. I've seen +// this happening on a WinXP SP1 box, especially when the application +// responsible for the UDP broadcasts isn't aware of the PPP interface. +// In this case it just uses the LAN IP src address for the IP src +// address of the inner (GRE encapsulated) IP packet. This breaks +// the "virtual LAN" and therefore bcrelay, as of this version, changes +// the src IP address to the VPN IP address (which pptpd provisioned) +// before relaying. +// 3) To avoid a UDP broadcast loop, bcrelay changes the IP TTL and the +// UDP checksum (to 1 and 0 respectively) of the UDP broadcasts it relays. +// No relaying will be done for UDP broadcasts with IP TTL=1 and UDP +// checksum=0. Could also (mis)use IP identification for this, but IP TTL +// and UDP chksum combination is expected to work fine. +// 4) bcrelay v0.5 forgot to update IP/UDP checksum when it changed the +// dest. IP address (e.g. from 192.168.1.255 to 255.255.255.255). +// Of course as of this version bcrelay always updates the IP/UDP +// checksum since the IP TTL and src IP address will change also. +// 5) Enhanced the (syslog) debugging capabilities. By default bcrelay will +// show what it is doing. Bcrelay will syslog the IP interfaces it tries +// to read/relay UDP broadcasts from/to. These interfaces are called +// the 'active interfaces', bcrelay will syslog the initial set of active +// interfaces and whenever the set changes. Currently there is no difference +// between an incoming interface (given with -i) and an outgoing interface +// (given with -o), so bcrelay won't show this attribute. Also, bcrelay will +// syslog a successfully relayed UDP broadcast, including the UDP port numbers, +// the incoming interface and the interface(s) to which it was successfully +// relayed. The (new) -n option allows to suppress syslog tracing. +// If -n is given, bcrelay shows/syslogs nothing, except fatal error +// messages. +// +// This software is completely free.

This is diagrammed below. + + _____ ___ ______ ______ +| | | \ | fire | | file | +| win | ---> / net \ ---> | wall | ---> | srvr | +|_____| \__/\_/ |______| |______| + + +The components of the system consist of the Win98 clients running the +built-in VPN facility dialing in to their ISP's and connecting through +the firewall to the Samba server on the internal network using the pptp +protocol. The firewall uses Network Address Translation to convert an +open Internet IP address to an internal one. Sounds simple enough +right? + +SIMPLE TEST SETUP + +As a starting point, I configured a Win98 box to connect directly to a +PoPToP server without any authentication or encryption. This was just +to get a feel for how pptp works and verify the setup. Using the +pre-packaged rpm's was a big help here. You just rpm the thing onto the +system and fire it up, and you're in business. The diagram below +represents this simple system. + + + 192.168.56.142 192.168.56.11 + _____ ______ + | | | file | + | win | ------------------> | srvr | + |_____| |______| + +Emboldend by my success, I set out to turn on MS authentication and +encrytion, and this is where the fun started. + +AUTHENTICATION AND ENCRYPTION + +This is an area where Microsoft really shows its true colors. Turning +on password and data encryption on the Win98 VPN server configuration +was quite the eye opening experience. First with the authentication, +you will have to go through a somewhat difficult compilation of the +ppp-2.3.8 package. The worst part here is getting all the pieces +together, namely the rc4 files. This process is well documented in this +archive, so I won't go into it here. + +The next realization is that Microsoft prepends the domain name to the +user name when submitting the login credentials. For example, srhodes is +now DBNET\\srhodes. If that wasn't bad enough, I found that the domain +wasn't even the one I was logged into. My best guess is that the first +domain that the computer ever logs into is stuck with it for ever. This +is a real problem if you have multiple domains that you log into. I +modified the pppd.c code to strip out the domain on MSCHAP logins, but +you can just set the user name in chap-secrets to match the windows +version. + +Then I spent a whole day trying to figure out why data encryption does +not work. I tried just about everything I could think of that could be +wrong. That's when I discovered this archive, for which I am truly +grateful. It turns out that the Win9x implementation of encrytpion is +FUBAR! You have to download one of those patches from Microsoft, +MSDUN 1.4 to get the thing to work. + +Windows 95 +http://download.microsoft.com/download/win95/Update/17648/W95/EN-US/dun14-95.exe + +Windows 98 +http://download.microsoft.com/download/win98/Update/17648/W98/EN-US/dun14-98.exe + +Windows 98se +http://download.microsoft.com/download/win98SE/Update/17648/W98/EN-US/dun14-SE.exe + + +FIREWALL CONFIGURATION + +The issue with a firewall in this setup is that you need to cover two +types of protocol communication. There is one connection which is a tcp +connection on port 1723 that handles the control functions and another +connection using IP type 47, or GRE, which handles the actual data +communication. This second connection presents a problem for the +convention linux firewall, ipfwadm. You see, its only set up to handle +tcp, udp and icmp protocols. It doesn't know about GRE. + +The trick around this block is to use one of the new 2.2 kernels, which +employ a new firewall called ipchains. This tool willl handle arbitrary +protocols, which can be specified by their numbers. + + + 192.168.2.142 192.168.56.11 + _____ ______ ______ + | | | fire | 192.168.56.1 | file | + | win | --------------->| wall | --------------> | srvr | + |_____| 192.168.2.1 |______| |______| + + + +You need to remember a few things before getting too deep into this. +The default gateway on win is set to 192.168.2.1, and the default +gateway on file srvr is set to 192.168.56.1. The firewall has the two +network interfaces spanning the two subnets and is configured for +IP forwarding. If you have not yet applied any firewall rules, this +configuration will work as before. The interesing part is to block out +all other access to file srvr by implementing ipchains rules. + +The short story is: + +ipchains -F +ipchains -P forward DENY +ipchains -I forward -p tcp -d 192.168.56.11 1723 -j ACCEPT +ipchains -A forward -p tcp -s 192.168.56.11 1723 -j ACCEPT +ipchains -A forward -p 47 -d 192.168.56.11 -j ACCEPT +ipchains -A forward -p 47 -s 192.168.56.11 -j ACCEPT + + +NETWORK ADDRESS TRANSLATION + +The next hurdle is to configure the firewall so that it can run an open +internet IP address on the outside and allow access to an internal +address on the inside. NAT is very well suited to this task, although +you may hear otherwise from knowledgable sources. It happens to be my +preference, though certainly not the only way to skin this cat. You can +obtain the NAT software and some detailed information from + +http://www.csn.tu-chemnitz.de/HyperNews/get/linux-ip-nat.html + +But again, there is a problem with the GRE protocol of type 47. The +tool for configuring NAT, ipnatadm, like its half-brother ipfwadm, is +not set up to handle arbitrary protocols. Unfortunately, you'll have to +go into the code and make a slight modification if you want to use it +for this purpose. There is a procedure called parse_protocol in the +file routines.c that discriminates the type of protocol to be filtered. +The basic idea is to accept a string representing a number and use that +as the filter. Since you have to recompile the kernel anyway to get the +NAT functionality, maybe it's not so horrible, relatively speaking. + +For those ambitous enough, here is the diff for the routines file, copy +this into a file called routines.diff and use the command patch -p0 < +routines.diff from within the same directory. + + +--- routines.c Thu Mar 25 15:41:58 1999 ++++ /mnt/zip/nat/routines.c Wed Jul 21 21:09:28 1999 +@@ -112,11 +112,18 @@ + else if (strncmp("icmp", s, strlen(s)) == 0) + nat_set.nat.protocol = IPPROTO_ICMP; + else { ++ int number; ++ char * end; ++ number = (int)strtol(s, &end, 10); ++ nat_set.nat.protocol = number; ++ } ++ /* ++ else { + fprintf(stderr, "ipnatadm: invalid protocol \"%s\" +specified\n", s); + exit_tryhelp(2); +- /* make the compiler happy... */ + return; + } ++ */ + } + + void parse_hostnetworkmask(char *name, struct in_addr **addrpp, __u32 +*maskp, int *naddrs) + + + +The patch is actually lifted from ipchains, which was derived from +ipfwadm, which provides the basis for ipnatadm. + +Once you've got all that running, what you want to do is to set up the +NAT rules so that the incoming client thinks its talking to the +firewall, as does the outgoing file server.

Very slick. + +SAMBA + +Here's a subject so complex you could probably devote a whole career to +it. We don't want to get too bogged down, so I'll be brief. Samba +implements the NetBIOS protocol, which has more quirks than you can +shake a stick at. One of the biggest problems is the use of subnet +broadcasting. Suffice it to say, if you want the best results, you +should set your PoPToP IP addresses to reside within the subnet on which +the file server ethernet is located. I choose 192.168.56.12 for the +server address, and it hands out IP's from 192.168.13-127. +Setting the IP forwarding on the file server to true will give you +access to other machines on the internal network. + +When you go at the samba sever from Win98, you have to use encrypted +password. Look at smbpasswd and related stuff. + +Finding shares on the server is not so easy. The short story here is +that browsing is implemented via broadcast packets, and broadcast +packets will not travel down a PPP link. The only way to get browsing +to work over pptp is to set Samba up as a WINS server and a Domain login +server, and configure the clients to use that WINS server and force them +to login to that Domain. Believe me, I tried just about everything to +avoid that. You will also want to set the samba server as the domain +master and preferred master for the browsing. + +If you can't do that, you can set the ppp/options file to include a +ms-wins setting for the samba server. This will set the client up so +they can at least resolve host names. The only way to find a share +under this configuration is to name it explicitly. You can use the +tools menu from the Win98 file browser and say find -> computer and +enter in the name of the samba server and it will be found. I have +found that setting domain master = yes and preferred master = yes gives +a rather nice boost to the speed of name lookups on the network. + +Here is my abbreviated smb.conf + +[global] + workgroup = VAULT + server string = acer + log file = /var/log/samba/log.%m + max log size = 50 + security = user + encrypt passwords = yes + smb passwd file = /etc/smbpasswd + socket options = TCP_NODELAY + domain master = yes + preferred master = yes + domain logons = yes + wins support = yes + dns proxy = no +[homes] + comment = Home Directories + browseable = no + writable = yes + +You should also use the lmhosts option for nmbd (-H) and set up an +lmhosts file on the samba server. Make sure also the the samba server +can resolve its own name, through either /etc/hosts or DNS. + +In all honesty , I went through the same simple test setup with samba as +I did for PoPToP, although its not shown here explicitly. + +CONCLUSION + +PoPToP is a good program, as is Samba. This configuration can work if +you put a little effort into it. I have seen a lot of questions here +and in other places about these types of systems, so I would think that +there is some demand on the part of users who want this type of +functionality. I hope these notes are useful to you if this is what you +want to do. + +**************************************************************************** +Q&A +I have a pptp server set up on my office LAN. I can connect to the +server and ping to it fine, but I can't ping any other hosts on the +office subnet. I have ip-forwarding turned on and I have proxyarp set +in the ppp/options file. What can be wrong? + +There seem to be a lot of questions floating around about routing and +masq'ing associated with this issue. + +Well, my curiosity got the best of me, so I thought I would check this +out. Shown below is my test setup for investigating this problem. + + +192.168.8.142 192.168.56.10 192.168.56.11 192.168.56.12 + ________ _______ ______ _____ +| | | | | | | | +| client |------->| fire |-------->| pptp |----->| host | +| | | wall | | srvr | | | +|________| |_______| |______| |______| + H H + H 192.168.8.10 H + H H + H===================================H +192.168.5.12 pptp connection 192.168.5.11 + + +For the sake of simplicity, we will ignore address translation issues +associated with the firewall. This assumes that the client at +192.168.8.142 is going to use 192.168.56.11 as its target address for +the pptp connection to pptp_srvr. The firewall will block all access to + +the 192.168.56.0 subnet except for pptp connections associated with +pptp_srvr. This can be implemented with ipchains + +ipchains -P input DENY +ipchains -P forward DENY +ipchains -A input 192.168.56.0/24 -j ACCEPT /* allow connections from + +inside */ +ipchains -A input -p tcp -d 192.168.56.11 1723 -j ACCEPT +ipchains -A input -p 47 -d 192.168.56.11 -j ACCEPT +ipchains -A forward -p tcp -d 192.168.56.11 1723 -j ACCEPT +ipchains -A forward -p tcp -s 192.168.56.11 1723 -j ACCEPT +ipchains -A forward -p 47 -d 192.168.56.11 -j ACCEPT +ipchains -A forward -p 47 -s 192.168.56.11 -j ACCEPT + +When you connect from client to pptp_srvr, you will be able to complete +the connection and ping to pptp_srvr. However, if you attempt to ping +host, at 192.168.56.12, this will fail. + +A clue to this problem can be found in the /var/tmp/messages file on +pptp_srvr. There, in the pppd messages, you will find + +Cannot determine ethernet address for proxy ARP + +This is due to an issue with the pppd program, which attempts to find a +hardware interface on the subnet to which the pppd client has been +assigned. In this case its looking for a hardware interface on the +192.168.5.0 subnet. It will fail to find one, and will drop the +proxyarp request. + +The simplest way around this problem, and the one that is suggested in +the pppd documentation, is to set the pppd client IP assignment to be on + +the local subnet. An example in this case might be 192.168.56.129. +However, it may not be possible to do that. In the case of a fully +loaded subnet, there may not be any addresses to spare. Or there may be + +some security issues with giving out local subnet addresses. What to +do? + +The place to look is in the arp table. If you run tcpdump on host +(192.168.56.12) during the time when client is pinging, you will see +unanswered arp requests from host attempting to find the hardware +address for 192.168.5.12. You need to proxy the hardware address of the + +pptp_srvr for client in order for this request to be fulfilled. This is + +the job of proxyarp. However, proxyarp has let us down in this +instance, and we need to find a workaround. + +This can be done manually using the arp command on pptp_srvr. For +example, if the hardware address of the ethernet card on pptp_srvr is +00:60:08:98:14:14, you could force the arp to proxy the client pptp +address by saying + +arp --set 192.168.5.12 00:60:08:98:14:13 pub + +You should now be able to ping from client to host through the pptp +connection. + +This can be a problem, however, in a dynamic environment when clients +are logging into and out of the pptp server on a continuous basis. One +way around this problem is to write a script that will execute upon the +initiation of each ppp connection. + +The place to do this is in /etc/ppp/ip-up. This script is executed each + +time a new ppp connection is started. It gets some variables passed +into it, one of which is the assigned IP address of the client. Note +that RedHat systems use ip-up.local as the place for you to make the +script. Don't forget to chmod +x ! + + +#! /bin/bash + +REMOTE_IP_ADDRESS=$5 + +date > /var/run/ppp.up +echo "REMOTE_IP_ADDRESS = " $REMOTE_IP_ADDRESS >> /var/run/ppp.up +arp --set $REMOTE_IP_ADDRESS 00:60:08:98:14:14 pub >> /var/run/ppp.up + +exit 0 + + +This should put you in business for accessing the remote subnet under +this scenario. I am a little bit concerned, however, because I also +built a script ip-down.local, that should remove the arp proxy when +client disconnected. It doesn't seem to do anything, however, and if I +try to delete the arp entry manually, it just spits out a cryptic error +message. The arp entries remain persistent, as far as I can tell. If +this is a problem or not, I don't know. The next few clients that log +in are treated well, so I guess its OK. + +**************************************************************************** +Q. +Also, after running pptpd and monitoring its log file and seeing that it +failed to open ttyp1 - I chmod +rw /dev/ttyp[0-9] and it seemed to work +somewhat. But, after I rebooted, I had to do this again. Is this normal? + +A. +pptpd should be running as root (unless you have a system with a setuid +openpty() helper, which isn't very common). If it fails to open a pty/tty +pair as root then that is probably because it is in use. + +Other programs which use pty/tty's will change their permissions back to +the standard ones. + +**************************************************************************** +Q. +sometimes when I make a connection to my pptpd server I +see a message like + +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-21 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-26 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-24 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-21 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-26 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-24 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-26 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-24 +Jul 2 17:30:03 ape modprobe: can't locate module ppp-compress-21 + + +in /var/log/messages on the server.

I downloaded +all of the patches and compiled everything but whenever i try to connect +from my win98 machine, it says: + +Error 691: The computer you have dialed in to has denied access because +the username and/or password is invalid on the domain. + +What is this suppose to mean? + +A. +Error 691 is an authentication problem probably due to the fact that MS +chap uses the domain name and username combo to authenticate. If you +look at the logs you will probably see a message saying that MS chap is +trying to authenticate user "domain\\username". I got it to work by +putting the full domain and user string in the client portion of the +chap-secrets file. + +# Secrets for authentication using CHAP +# client server secret IP +addresses +workgroup\\user server password * + +If anyone knows how to get it to default to a particular domain, I would +like to know. + +**************************************************************************** +Q. +how do I go about checking who is logged in via tunnel? + +I need some way of writing the pppd data to wtmp/utmp. +(and not sessreg either) + +does anyone know of any way of doing this via ppp? + +A. +pppd syslogs everything to /var/log/messages (that's the default on my box +anyways) and it will say something like : +pppd[15450]: CHAP peer authentication succeeded for <username> + +you could do a tail /var/log/messages -n2000 | grep CHAP if you wanted to +see who has been logging in. + +other than that, there's not much i know of. all the authentication is +provided by pppd (if you don't have an auth or a require-chap (or pap, etc.) +option, it doesn't even ask for a username. + +**************************************************************************** +Q. +My NT client won't connect! + +A. +Try taking header and software compression off. + + +**************************************************************************** +Q. PPTP *client* stops working. + +A. +go to /var/run/pptp/ and look for a socket named x.x.x.x +delete it and try it again. + +**************************************************************************** +Q. +How many clients does PoPToP support? + +A. +The limits under Linux are: + + per-process filedescriptors + - one per client (would limit clients to 256 by default, + or 1024 with kernel recompile, or more with major libc/kernel + hackery) + - no relevant limit + + ttys - currently, with a standard kernel, 256 clients + - with Unix98 ptys and a small amount of coding, 2048 + + ppp devices + - no limit in kernel source for ppp + - limit of 100 in dev_alloc_name() in 2.2.x + + for(i=0;i<100;i++) + { + sprintf(dev->name,name,i); + if(dev_get(dev->name)==NULL) + return i; + } + + best fix is probably to keep a static int ppp_maxdev so you + don't end up doing 2000 dev_get's to allocated the 2001'th + device. + + processes + - 2 per client plus system processes + - standard kernel max = 512 processes, ie 256 clients + - i386 max = 4096 processes, ie 2048 clients + +So it seems that 2048 will be the limit, if you fix a few things and +with a minor kernel mod (I could do all of these pretty easily and send +you a trivial kernel patch). To go above 2048 the easiest approach would +be to combine pptpctrl and pppd in one process, which would get you to +4096. Beyond there, you need to go for a select() based model, which would +be significant coding effort and require large fd-set sizes and so on. +So 4096 is the practical limit, and 2048 the easy limit. + +**************************************************************************** +Q. +What authentication methods (PAP/CHAP) does PoPToP work with? + +A. +PoPToP uses whatever authentication methods your PPPd provides (usually +PAP and CHAP). With PPPd patches you can get MSCHAP and MSCHAPv2 +authentication as well. + +**************************************************************************** +Q. +When running PoPToP I get the following error: + + Jun 11 08:29:04 server pptpd[4875]: MGR: No more free connection slots! + +What does this mean? + +A. +I'd say at a guess you've only configured one IP address and you have +connected a client, and as such there are no more free connection slots should +any more clients wish to connect. + +**************************************************************************** +Q. +Does PoPToP suffer from the same security flaws +(http://www.counterpane.com/pptp.html) as the Windows NT PPTP server? + +A. +An initial look at the article suggests that what the authors hammered was +not the PPTP protocol, but the authentication that the PPTP VPN servers on +NT offered access to via open internet. PPTP seems initially to be just +the path to the weakness, not the weakness itself. Part of their +observance of weakness deals with use of poor passwords as well, a cheap +component, simple enough to fix. + +> While no flaws were found in PPTP itself, several serious flaws were +> found in the Microsoft implementation of it. +> (http://www.counterpane.com/pptp-pressrel.html) + +The authors do not specifically say "this is ONLY effective against NT", +just that NT is affected. This implies that they do not recognize PoPToP, +and it may be included. The fact that PoPToP has to interOp with MS DUN's +VPN client means that it will have the same weaknesses. It can only +protect itself from DoS attacks, have immediate response to out-of-sequence +packets or illogical packets, etc. + +The protocol is not considered weak in this analysis, but the weaknesses +have to be replicated in apparent behavior by PoPToP. The only thing the +developers can do with PoPToP is make it a stronger server per se -- more +able to handle the attacks when the come. + +In conclusion: PoPToP suffers the same security vulnerabilities as the NT +sever (this is because it operates with Windows clients). + +Update: MSCHAPv2 has been released and addresses some of the security +issues. PoPToP works with MSCHAPv2. + +**************************************************************************** +Q. +Does PoPToP support data encryption? + +A. +Yes.. with appropriate PPPd patches. Patches are available for PPPd to +provide Microsoft compatible RC4 data encryption. The PPPd patch supports +40 and 128 bit RC4 encryption. + +**************************************************************************** +Q. +PoPToP or IPsec? Which is better suited to my needs? + +A. +1. The difference between PoPToP and IPsec is that PoPToP is ready NOW.. +and requires *no* third party software on the Windows client end +(Windows comes with a free PPTP client that is trivial to set up). + +2. PoPToP is a completely *free* solution. +Update: Unfortunately not true for Mac *clients* though. The Mac client +software is around $400 US a copy. + +3. PoPToP can be integrated with the latest PPPD patches that take +advantage of MSCHAPv2 and MPPE (Microsoft encryption using RC4 - 40/128 +bits). + +More details follow from Emir Toktar: +(Refs: A Comprehensive Guide to Virtual Private Networks, IBM. +Virtual Private Networking: An Overview White Paper - DRAFT, 3/18/98 +Microsoft.) + +Neither network layer-based (L2TP, PPTP,...) nor application layer-based +(IPSec,SSL,SSH) security techniques are the best choice for all +situations. There will be trade-offs. Network layer security protects the +information created by upper layer protocols, but it requires that IPSec +be implemented in the communications stack. + +With network layer security, there is no need to modify existing upper +layer applications. On the other hand, if security features are already +imbedded within a given application, then the data for that specific +application will be protected while it is in transit, even in the absence +of network layer security. Therefore security functions must be imbedded +on a per-application basis. + +There are still other considerations: +Authentication is provided only for the identity of tunnel endpoints, but +not for each individual packet that flows inside the tunnel. This can +expose the tunnel to man-in-the-middle and spoofing attacks. + +Network layer security gives blanket protection, but this may not be as +fine-grained as would be desired for a given application. It protects +all traffic and is transparent to users and applications. + +Network layer security does not provide protection once the datagram has +arrived at its destination host. That is, it is vulnerable to attack +within the upper layers of the protocol stack at the destination machine. + +Application layer security can protect the information that has been +generated within the upper layers of the stack, but it offers no +protection against several common network layer attacks while the +datagram is in transit. For example, a datagram in transit would be +vulnerable to spoofing attacks against its source or destination address. + +Application layer security is more intelligent (as it knows the +application) but also more complex and slower. + +IPSec provides for tunnel authentication, while PPTP does not. + +<User Authentication> Layer 2 tunneling protocols inherit the user +authentication schemes of PPP, including the EAP methods discussed below. +Many Layer 3 tunneling schemes assume that the endpoints were well +known (and authenticated) before the tunnel was established. An exception +to this is IPSec ISAKMP negotiation, which provides mutual authentication +of the tunnel endpoints. (Note that most IPSec implementations support +machine-based certificates only, rather than user certificates. As a +result, any user with access to one of the endpoint machines can use +the tunnel. This potential security weakness can be eliminated when +IPSec is paired with a Layer 2 protocol such as L2TP. + +<Token card support> Using the Extensible Authentication Protocol +(EAP), Layer 2 tunneling protocols can support a wide variety of +authentication methods, including one-time passwords, cryptographic +calculators, and smart cards. Layer 3 tunneling protocols (IPSec) can +use similar methods; for example, IPSec defines public key certificate +authentication in its ISAKMP/Oakley negotiation. + +<Dynamic address assignment> Layer 2 tunneling supports dynamic +assignment of client addresses based on the Network Control Protocol +(NCP) negotiation mechanism. + +Generally, Layer 3 tunneling schemes assume that an address has already +been assigned prior to initiation of the tunnel. Schemes for assignment +of addresses in IPSec tunnel mode are currently under development and +are not yet available. + +<Data Compression> Layer 2 tunneling protocols support PPP-based +compression schemes. For example, the Microsoft implementations of both +PPTP and L2TP use Microsoft Point-to-Point Compression (MPPC). The IETF +is investigating similar mechanisms (such as IP Compression) for the +Layer 3 tunneling protocols. + +<Data Encryption> Layer 2 tunneling protocols support PPP-based data +encryption mechanisms. Microsoft's implementation of PPTP supports +optional use of Microsoft Point-to-Point Encryption (MPPE), based on +the RSA/RC4 algorithm. Layer 3 tunneling protocols can use similar +methods; for example, IPSec defines several optional data encryption +methods which are negotiated during the ISAKMP/Oakley exchange. + +<Key Management> MPPE, a Layer 2 protocol, relies on the initial key +generated during user authentication, and then refreshes it +periodically. IPSec, explicitly negotiates a common key during the +ISAKMP exchange, and also refreshes it periodically. + +<Multi-protocol support> Layer 2 tunneling supports multiple payload +protocols, which makes it easy for tunneling clients to access their +corporate networks using IP, IPX, NetBEUI, and so forth. In contrast, +Layer 3 tunneling protocols, such as IPSec tunnel mode, typically +support only target networks that use the IP protocol. IPSec is not +multi-protocol. + +IPSec will be suported by Windows 2000. + +Many cases can occur, each of which needs to be examined on its own +merit. It may be desirable to employ a mix of both network layer +security techniques and application layer techniques to achieve the +desired overall level of protection. For example, you could use an upper +layer mechanism such as Secure Sockets Layer (SSL) to encrypt upper +layer data.

Introduction</strong> +<p>This document descibes how to build a Linux PPTP server with Poptop and use Microsoft Active Directory to authenticate users. There are a few howtos on this topic, such as the <a href="http://poptop.sourceforge.net/dox/replacing-windows-pptp-with-linux-howto.phtml">Replacing a Windows PPTP Server with Linux Howto</a> maintained by Matt Alexander. Most of them, however, concentrate on Samba and winbind. I followed them and got it working in the test environment. Unfortunately, winbind does not scale very well in a AD setup which has thousands of objects. The AD in my work is a big tree. It spans across all continents and has thousands of users and groups. Winbind simply times out before it can harvest a complete list of users/groups.</p> +<p align="left">The other way of doing it is with radius. Information on how to setup pptpd with radius against Active Directory is scarce. I can only find bits and pieces information from forums but never find any comprehensive documents. I spent days to try to get it configured properly. After countless frustrations and tears, I eventually got a working setup. I therefore decided to make this howto to document it. Hopefully, you will find it useful.</p> +<p align="left">To make this howto complete, I include the winbind configuration as well although it may duplicate Matt's work.</p> +<p align="left"><strong>Note</strong>: this howto is based on Fedora Core 4 and use pre-packaged RPMs whenever possible. If you are using other distributions or like to compile software, you will have to make the necessary adjustments.</p> +<hr> +<strong><a name="disclaimer"></a>2.

The first one is /etc/pptpd.conf. You can very much keep it as it is except the ip address range for the ppp connections. Edit the file and add two lines at the bottom to specify the local ip address and the ip address pool for the remote connections. </p> +<blockquote> + <pre>localip 10.0.0.10<br>remoteip 10.0.0.101-200 </pre> +</blockquote> +<p>10.0.0.10 is the ip address of the internal network card eth0. The remoteip is the address pool for the remote connections. </p> +<p>The second configuration file is /etc/ppp/options.pptpd. I stripped off all remarks from my options.pptpd and it is like this:</p> +<blockquote> + <pre>name pptpd +refuse-pap<br>refuse-chap<br>refuse-mschap<br>require-mschap-v2<br>require-mppe-128 +ms-dns 10.0.0.1 +ms-wins 10.0.0.1 +proxyarp +lock +nobsdcomp +novj +novjccomp +nologfd +auth +nodefaultroute +plugin radius.so +plugin radattr.so</pre> +</blockquote> +<p>There are two plugins we used in here. The first one radius.so is required while the second one radattr.so is optional. Radattr.so basically records the parameters passed from radius to pppd in a file. Check the man page of pppd-radattr for details. </p> +<p>Then, we need to fix the permission of a winbind directory.</p> +<blockquote> + <pre>[root@pptp ~]# chgrp radiusd /var/cache/samba/winbindd_privileged/</pre> +</blockquote> +<p>If you have Windows XP clients, you may want to reduce the MTU size. Add the line, /sbin/ifconfig $1 mtu 1400, to /etc/ppp/ip-up as shown in the following list.</p> +<blockquote> + <pre>[root@pptp ppp]# cat ip-up +#!/bin/bash +# This file should not be modified -- make local changes to +# /etc/ppp/ip-up.local instead + +PATH=/sbin:/usr/sbin:/bin:/usr/bin +export PATH + +LOGDEVICE=$6 +REALDEVICE=$1 + +[ -f /etc/sysconfig/network-scripts/ifcfg-${LOGDEVICE} ] && /etc/sysconfig/network-scripts/ifup-post ifcfg-${LOGDEVICE} + +/etc/ppp/ip-up.ipv6to4 ${LOGDEVICE} + +[ -x /etc/ppp/ip-up.local ] && /etc/ppp/ip-up.local "$@" + +<strong>/sbin/ifconfig $1 mtu 1400</strong> +exit 0</pre> +</blockquote> +<p>The above example reduces the MTU size to 1400. In my environment, I found that XP will connect the VPN and ping all servers without problems, however, it cannot connect to the Microsoft Exchange server properly. Reduce the MTU size to 1400 fixed the problem.</p> +<p>After fixing the files and permission, we can start pptpd and connect to it from remote client.

This is the recommended way of implementing VPN for security reasons.</p> +<hr> +<strong><a name="splittunnel"></a>15.1 Split Tunneling</strong> +<p>Split Tunneling allows you to configure the network so that only selected traffic is directed to the VPN tunnel. For instance, you want browsing traffic to go to the Internet directly but corporate traffic goes via the VPN, then you will need split tunneling. It is also important if your ISP requires a heatbeat from your machine to keep the connection alive. </p> +<p>While split tunneling provides convenience, it causes security problems because <span name="intelliTxt" id="intelliTxt">it essentially renders the VPN vulnerable to attack as it is accessible through the public, non-secure network. Check your company security policy before inplementing split tunneling. </span></p> +<p>To set up split tunneling:</p> +<ul> + <li>Right click on the icon which you created in section 15 and choose Properties.</li> + <li>Choose the Networking tab. Highligth the Internet Protocol (TCP/IP) and click on the Properties button.</li> + <li>Click on the Advanced Button and then deselect "Use default gateway on remote network". Click OK. Click OK and then click OK.</li> +</ul> +<p>If you have a simple private network which has only one single segment, you have finished the configuration. Take a break and enjoy you day.</p> +<p>If you have multiple subnets in the private network, there are still works to do. By not using the PPP as the default gateway, we introduce another problem. The PPP client will set up routing only to the subnet that is directly attached to the pptp gateway. Traffic will not route to the other subnets. In our test environment, you can only access 10.0.0.0 but not 172.16.0.0. To resolve this problem, I created a VBScript to add the extra routes. </p> +<p>The VBScript is listed here: </p> +<blockquote> + <pre>Option Explicit<br>Dim IP_Address<br>Dim TmpFile : TmpFile = "c:\ip.txt"<br>Dim route1 + +<strong>route1 = "route add 172.16.0.0 mask 255.255.255.0 "</strong> + +SaveIP<br>IP_Address = GetIP()<br>route1 = route1 & IP_Address<br>AddRoute + +Sub SaveIP<br> Dim ws : Set ws = CreateObject("WScript.Shell")<br> ws.run "%comspec% /c ipconfig > " & TmpFile, 0, True<br> Set ws = Nothing<br>End Sub + +Function GetIP()<br> Dim fso : Set fso = CreateObject("Scripting.FileSystemObject")<br> Dim re : Set re = New RegExp<br> re.Global = TRUE + + Dim file, fileline, matches<br> Dim pppsection : pppsection = FALSE + + If fso.FileExists(TmpFile) Then<br> Set file = fso.OpenTextFile(TmpFile)<br> + Do While Not file.AtEndOfStream<br> fileline = file.ReadLine + + If Not pppsection Then + If left(fileline,3) = "PPP" Then + pppsection = TRUE + End If + Else + re.Pattern = "IP Address[\. ]+: " + If re.Test(fileline) Then + matches = split(fileline,":") + GetIP = right(matches(1),len(matches(1))-1) + End If + End If + + Loop<br> file.Close<br> End If + + Set re = Nothing<br> Set fso = Nothing<br>End Function + +Sub AddRoute<br> Dim ws : Set ws = CreateObject("WScript.Shell")<br> ws.run "%comspec% /c " & route1, 0, True<br> Set ws = Nothing<br>End Sub +</pre> +</blockquote> +<p>Create the VBScript file somewhere in your PC and create a shortcut on the desktop.
