Looks like ethereal is pretty popular.  Unfortunately, rpmfind reports 58
other required rpms to install it, and experience tells me that first,
rpmfind will never get through a list like that, and second that if it did
it would probably hose my system.  What I'll probably do is build a Mandrake
Secure Firewall system and put it on that - I've been planning to do so for
a while as I looked for ways to update this system.
