My experience with Livingston PortMasters was a great experience.  PortMasters, 
Cisco 2511 w/Octopus cables, and lots of US Robotics modems encompassed my early 
ISP experiences.

If I recall correctly, Livingston came up with the RADIUS authentication 
protocol, and open-sourced it for us all to enjoy.

Lots of fun with RADIUS and TACACS in its various forms.  I have not had the 
opportunity to work with the DIAMETER protocol yet.

Thanks for sharing.
