tcpspy - 1.7d-15 main

tcpspy is an administrator's tool that logs information
about incoming and outgoing TCP/IP connections. It's
written in C and uses no libpcap functions, unlike tcpdump.
.
Connections are selected for logging with rules, similarly
to the filter expressions accepted by tcpdump. The
following information is logged: username, local address
and port, remote address and port, and, optionally, the
executable filename.
.
This Debian version supports IPv4 and IPv6.
