.TH "tcptrack" 1
.SH NAME
tcptrack \- Monitor TCP connections on the network
.SH SYNOPSIS
.B tcptrack
tcptrack [-hv] -i <interface> [<filter expression>]
.SH DESCRIPTION
tcptrack displays the status of TCP connections that it sees on a given
network interface. tcptrack monitors their state and displays information
such as state, source/destination addresses and bandwidth usage in a sorted,
updated list very much like the top(1) command.

The filter expression can be used to filter down the characteristics of TCP
connections that tcptrack will see. See tcpdump(8) for more information
about the syntax of this expression.

.SH BUGS
Currently the interface is not very flexible. Display timing settings (such
as the refresh interval) can only be changed by editing the source code
(defs.h in particular). See the TODO file included with the source
distribution for further bugs.
