The trouble making host is an FC2? This is not very clear from your
description. But I does not really matter.

Fedora is not Redhat - see http://fedora.redhat.com. You are using
Fedora Core and not Redhat Linux.

Says not much. Modem bandwidth is not much. If the systems are connected
through ethernet it will be much traffic. And you did not say any word
as what kind of server this host is acting. Is it running a webserver,
DNS services, a mail server, even an MTA?

Just a blind shot: are you running a misconfigured MTA on the "victim"
host which is acting as an open relay? This can typically explain the
traffic. A misconfigured DNS can cause such constant high traffic too.

The directory /var/log/ is full of log files. It is always the first
place to look at. Most important log files are messages, secure and if
running an MTA the maillog.
