In moving our RADIUS infrastructure to FreeRADIUS, I wrote a tee to transparently compare FreeRADIUS' responses with those of our existing Radiator installations. It sniffs RADIUS traffic on the current machine, replays the requests to another RADIUS server, and compares the received responses with the sniffed responses. Differences are emitted to stdout, and known differences can be configured so they're automatically ignored. http://horde.net/~jwm/software/misc/comparison-tee john -- John Morrissey _o /\ ---- __o jwm@horde.net _-< \_ / \ ---- < \, www.horde.net/ __(_)/_(_)________/ \_______(_) /_(_)__
