oh. generally you do all the accounting and pre-paid
stuff and timing of sessions etc on the SERVER. all the
required bits are already there. various rlm_* modules
that can interface nicely to a database backend etc.

you can see the stuff with tcpdump (in the usual way) but there
are special filters for RADIUS in ethereal package - which some
people prefer to use when looking at the network stuff. you
could look at the server end still - since you can see all the
into that the server sends and that the server receives. if
you have a problem with the network so that packets dont arrive
than thats another issue altogether.

ah. if you are ONLY seeing this and yet you are trying to run the radclient
on another box...then the packets arent arriving to the server. in this
case perhaps there is a firewall in the way (usual suspect and reason).
if you have misconfigured the client/server relationship (wrong passphrase
etc) then you would see info...and it would tell you!
