It contains a list of all currently tracked -connections through the system. If you don't use connection tracking -exemptions (NOTRACK iptables target), this means all connections that go -through the system. -.TP -.BR "expect" : -This is the table of expectations. Connection tracking expectations are the -mechanism used to "expect" RELATED connections to existing ones. Expectations -are generally used by "connection tracking helpers" (sometimes called -application level gateways [ALGs]) for more complex protocols such as FTP, -SIP, H.323. -.SH OPTIONS -The options recognized by -.B conntrack -can be divided into several different groups. -.SS COMMANDS -These options specify the particular operation to perform. Only one of them -can be specified at any given time. -.TP -.BI "-L --dump " -List connection tacking or expectation table -.TP -.BI "-G, --get " -Search for and show a particular (matching) entry in the given table. -.TP -.BI "-D, --delete " -Delete an entry from the given table. -.TP -.BI "-I, --create " -Create a new entry from the given table. -.TP -.BI "-E, --event " -Display a real-time event log. -.TP -.BI "-F, --flush " -Flush the whole given table -.SS PARAMETERS -.TP -.BI "-z, --zero " -Atomically zero counters after reading them. This option is only valid in -combination with the "-L, --dump" command options. -.TP -.BI "-e, --event-mask " "[ALL|NEW|UPDATES|DESTROY][,...]" -Set the bitmask of events that are to be generated by the in-kernel ctnetlink -event code. Using this parameter, you can reduce the event messages generated -by the kernel to those types to those that you are actually interested in. -. -This option can only be used in conjunction with "-E, --event". -.SS FILTER PARAMETERS -.TP -.BI "-s, --orig-src " IP_ADDRESS -Match only entries whose source address in the original direction equals the one specified as argument. -.TP -.BI "-d, --orig-dst " IP_ADDRESS -Match only entries whose destination address in the original direction equals the one specified as argument. -.TP -.BI "-r, --reply-src " IP_ADDRESS -Match only entries whose source address in the reply direction equals the one specified as argument. -.TP -.BI "-q, --reply-dst " IP_ADDRESS -Match only entries whose destination address in the reply direction equals the one specified as argument. -.TP -.BI "-p, --proto " "PROTO " -Specify layer four (TCP, UDP, ...) protocol. -.TP -.BI "-f, --family " "PROTO" -Specify layer three (ipv4, ipv6) protocol -This option is only required in conjunction with "-L, --dump". If this option is not passed, the default layer 3 protocol will be IPv4. -.TP -.BI "-t, --timeout " "TIMEOUT" -Specify the timeout. -.TP -.BI "-u, --status " "[ASSURED|SEEN_REPLY|UNSET|SRC_NAT|DST_NAT][,...]" -Specify the conntrack status. -.TP -.BI "-i, --id " "ID" -Specify the conntrack ID. -. -This option can only be used in conjunction with "-L, --dump" to display the conntrack IDs. -.TP -.BI "--tuple-src " IP_ADDRESS -Specify the tuple source address of an expectation. -.TP -.BI "--tuple-dst " IP_ADDRESS -Specify the tuple destination address of an expectation. -.TP -.BI "--mask-src " IP_ADDRESS -Specify the source address mask of an expectation. -.TP -.BI "--mask-dst " IP_ADDRESS -Specify the destination address mask of an expectation. -.SH DIAGNOSTICS -The exit code is 0 for correct function. Errors which appear to be caused by -invalid command line parameters cause an exit code of 2. Any other errors -cause an exit code of 1. -.SH BUGS -Bugs? What's this ;-) -.SH SEE ALSO -.BR iptables (8) -.br -See -.BR "http://netfilter.org/" . -.SH AUTHORS -Jay Schulist, Patrick McHardy, Harald Welte and Pablo Neira wrote the kernel-level "ctnetlink" interface that is used by the conntrack tool. -.PP -Pablo Neira wrote the conntrack tool, Harald Welte added support for conntrack based accounting counters. -.PP -Man page written by Harald Welte <laforge@netfilter.org>. |
