Aha!

In that case you could always download a copy of lsof and compile it
locally.

lsof == (literally) LiSt Open Files

With the -i switch it doesn't just show open ports, it shows the files
opened by the processes which have those ports open. It's a *lot* more
verbose that netstat, but in some cases I find it a whole load more useful.
Especially when I suspect there's something Not Quite Right with a machine
and something's hiding from me...

Again though as mentioned by Steve Werby, it might be a little difficult to
find an RPM for this. Use the source :)
