RADIUS runs like a champ on Linux. It should run fine with Ciscos, but my
RADIUS experience is primarily with Lucent Portmasters. Contact me off-list
for the e-mail address of an owner of another ISP who may be able to help
you configure RADIUS on a Cisco NAS.

I've been using Merit AAA, but the licensing is rather strict and it's based
on old code. Look for the Cistron RADIUS server on - there are
links to both source and binary packages.

The most important part of getting RADIUS running on your Linux box is
making sure your dictionary file contains vendor-specific entries for the
brand of NAS that you are using. If you're using any one of the major brands
- Cisco, Bay, Ascend, 3Com/USR - this is a non-issue.

Again, I can't help you configure things on the Cisco, but I can help you
get things running on the Linux box; feel free to contact me if you need
some advice.
