About two years ago with linux 1.2.13, I ran two modem servers with
24-ports each for quite a while. I used Cyclades cards and 486's with
16-24MB ram. The kernel has changed quite a bit, but these computer would
go for a couple months without a lockup. It was a lot of work to setup one
of these and get the passwords distributed to the different modem server,
and no linux radius clients were available then for keeping track of the
usages, etc...
I'd recommend a used Portmaster2e30 or something. These can be had for $US
800-1100, and are worth every penny. Authentication is handled with free
Radius software on linux, and I have more than a dozen of these being
handled from one linux Pentium. The actual authentication uses very little
ram or CPU power; a 486 or low end pentium would do. It's a great way to
centralize all the names and passwords for the dial ups. I installed a
Portmaster modem server in a neighboring town three years ago, and haven't
seen it for two years now. It's still going...
