Sorry, I didn't include the ipchains on the previous post. I did have all the
firewall settings turned off, so ipchains -L didn't do anything. I just
configured using lokkit which in turn edits the /etc/sysconfig/ipchains file.
Running ipchains -L now gives:
[root at space redhat]# /sbin/ipchains -L

And now for the netstat command...
