Re: FreeRadius

>what RADIUS servers do people use here? are they GPL'd? Good? etc?

I use a lot of xtradius, it's derived from Cistron which got wrapped into
FreeRadius, although I think their code was a series of improvements on the
original livingston radiusd.

The neat thing about xtradius is that you can use a script to determine what
it returns. Exiting zero allows access, exiting anything else denies it,
based on an environment or parameters setup by your radius client. You can
also print values from the script to stdout, and they end up as radius
returned attributes. This is really useful for database driven systems and
near-realtime accounting.. I personally find log/cron based systems to not
make best use of available technology, why not be able to see what's going
on at any given moment?

I also had some input into the development (my cool idea to use the
environment like CGI, my bad for exposing radius passwords with 'ps -e' as a
result) and did some patches for xtradius, so perhaps I'm a little biased ;)

A similar commercial product is radiator, that lets you do the above in
Perl, and get support from the (Australian) author.
Perlradius is another easily modified radius daemon, great for building
custom radius proxies if you want to keep it all perl. Also Australian made
(iinet).
