I'm quite aware of things like portsentry, pf (I have an OpenBSD server),
ipf etc, but unfortunately this isn't what I'm looking for. I'm not after a
firewall or a TCP filter; A proxy server works at a higher level,
specifically handling individual protocols. Sure I can use a packet filter
to examine traffic on port 80, but a TCP filter doesn't usually know
anything about HTTP, it just knows packets. A TCP dump would give me buckets
of messy raw data (that would contain, somewhere, the data I'm interested
in, but not in any useful way), but it's just presented at the wrong level.
It's kind of like using a microscope to read a road map.
NAME ethereal - Interactively browse network traffic
DESCRIPTION
Ethereal is a GUI network protocol analyzer. It lets you
interactively browse packet data from a live network or
from a previously saved capture file.
