Hi Hugh,
We have a serious problem regarding ISDN port check on Ciscos by Radiator.
As an ISP, we have to provide 128k ISDN connections to our customers. To
open a 128k ISDN connection, the user first opens the first 64k channel,
authenticates once, and then opens the second 64k channel, doing a second
authentication. This is a procedure that relies heavily on being sure about
how many simultaneous connections a user has open on a given time. Because,
if the system thinks a user is already connected it won't let him open the
second 64k channel, and if the system thinks a 64k user isn't connected it
will let him connect at 128k! If we do not check the simultaneous sessions,
then all ISDN users will connect at 128k.
Here is where NAS double checking features comes in hand. The problem with
Ciscos is that the ISDN ports (ranging from 20000 to 20xxx) cannot be double
checked using SNMP, in contrast with the normal PSTN ports (1-xxx). So we
cannot guarantee that a user will connect at the right speed, because some
times Radiator looses the count of simultaneous user sessions.
The point is:
Is it possible for you to make Radiator check for simultaneous logins using
finger instead of SNMP?
Or, is there another solution to this problem that someone else has
implemented successfuly?
Thanks in advance
Nikos Aslanakis
