Thanks for all private and public answers. Besides the two I mentioned
on the original posting (NavisRadius and Interlink), two other RADIUS
servers seems to be quite popular and trusted by various NANOG readers:
- Radiator (www.open.com.au/radiator)
- Steel-Belted Radius (www.funk.com)
The following products have received one or two mentions:
- Widespan (http://www.bridgewatersys.com/)
- FreeRadius (http://www.freeradius.org)
- GNU RADIUS (http://www.gnu.org/software/radius/)
- Navipath (no longer in business)
- Cisco Access Registrar (http://www.cisco.com/go/ar)
