man tcplog (Administration système) - TCP packet logger.

NAME

tcplog - TCP packet logger.

SYNOPSIS

tcplog [-f, --file filename ] [-n, --no-resolve] [-v, --version]

DESCRIPTION

tcplog , a TCP packet logger, is a part of the jail (just another ip logger) package.

tcplog is a small (daemon) process which logs all TCP connection requests to the local host. The syslog level at which a given packet is logged is configurable depending on the destination port. Packets from specific hosts can be ignored, and a default log level can be specified.

tcplog can be useful in detecting attempted denials of service, and monitoring network traffic, especially when used in conjunction with icmplog(8).

The configuration is explained in the tcplog.conf(5) manual page.

OPTIONS

-f, --file [ filename ]
Use filename as the configuration file instead of the default (/etc/tcplog.conf).
-n, --no-resolve
Do not resolve IP addresses to hostnames.
-v, --version
Display tcplog(8) version.
