noob with some questions

Thanks for your reply. Unfortunately, the FreeRadius documentation and 
support is so abysmal and my experience too limited to make good use of 
the advice you gave. Each OSS package has its benefits and weaknesses I 
guess. For instance I've used ISC DHCP server for years and it has 
stellar support from the programmer, great on-line information and 
documentation so much so that I can't imagine using anything else. I 
guess I was hoping FreeRadius would have the same support. Without a 
doubt it doesn't. I've spent about two weeks now struggling to make the 
software do what I want and at this point I give up. I'm moving on to 
Radiator. I just can't spend any more time spinning my wheels.

Perhaps in the future the FreeRadius writer's will realize how useless 
their software is with the level of documentation and support they are 
providing and choose to make improvements or maybe they'll just continue 
to operate on a "you get what you pay for basis." Either way it's not 
worth the frustration. It's a shame really because it's obvious that it 
is a really good piece of software.

Anyway, thanks again for the reply.
