Overview
--------
The ACCEL-PPTP v1.0 is completly new implementation of PPTP/PPPoE/L2TP which was written from null.
Userspace daemon has its own PPP implementation, so it does not uses pppd and one process (multi-threaded) manages all connections.
ACCEL-PPTP uses kernel module to increase performance and decrease system usage.
It is not fully tested yet so not recomended to use in production.
Also v1.0 is oriented for servers and does not containes client part, if you need client please use v0.8.x
Features
--------
1. Modular architecture
2. High-performance multi-threaded I/O core
3. Supported PPTP
4. Supported PPPoE
5. Supported L2TPv2 (without IPsec)
5. Radius authentication/accounting
6. Radius DM/CoA extention
7. Supported authentication types: PAP, CHAP (md5), Microsoft CHAP Extentions (including version 2), not supported - EAP
8. Supported MPPE
9. Compression is not supported
10. Extensible logging engine with per session logging support, implemented log to file and log to PostgreSQL targets
11. Extensible user/password database, implemented only Radius source
12. Extensible IP pool, implemented Radius and static pools
13. Supported pppd compatible ip-up/ip-down scripts
(Work on L2TP is in progress)
Requirment
----------
1. modern linux distribution
2. kernel-2.6.25 or later
3. glibc-2.8 or later
4. cmake-2.6 or later
5. libnl-1.1 or probably later
Compilation and instalation
-----------
Make sure you have configured kernel headers in /usr/src/linux,
or specify other location via KDIR.
1. cd /path/to/accel-pptp-1.0
2. mkdir build
3. cd build
4. cmake [ -D BUILD_DRIVER=TRUE ] [ -D KDIR=/usr/src/linux ] [ -D CMAKE_INSTALL_PREFIX=/usr/local ] [ -D CMAKE_BUILD_TYPE=Debug ] [ -DLOG_PGSQL=TRUE ] ..
Please note that the double dot record in the end of the command is essential. You'll get error if you miss it.
BUILD_DRIVER, KDIR, CMAKE_INSTALL_PREFIX, CMAKE_BUILD_TYPE, LOG_PGSQL are optional,
but while pptp is not present in mainline kernel you probably need BUILD_DRIVER.
5. make
6. make install
Configuration
-------------
read man accel-pptp.conf
Warning !!!
-----------
1. This driver conflicts with ip_gre driver (in kernel), so make sure that ip_gre is not built-in or loaded at run time.
2. Never mix connections of accel-pptp and original pptpd, before starting accel-pptp make sure that no connections
of original pptpd exists.
Thanks

Thanks to Kirill Yushkov for debug support and donations.
