OK. This is a lot of information, so I hope you don't mind. I spent the
entire day today trying to help myself figure this out (reading documentation,
testing various configs, googling, etc), but I'm just at a loss. Maybe you
can help. I'll try to be concise.
For reference, I'm running Radiator 2.18.1 on a BSDi 4.1 machine (the
thorn in my flesh. This is a legacy machine that I *will* be getting rid
of sometime soon, but for now I'm stuck with it) as my PRIMARY authentication
server. My PRIMARY accounting server is running Radiator 2.18.4 on FreeBSD
4.6.2-RELEASE. I don't *think* this should cause any problems with the two
session databases, but I could be very wrong. I know very little about
Radiator and I'm not the person that set these two versions up. If this
is a problem, please let me know and why.
Please see attached for my radius.cfg - minus the Secrets. The realm we're
dealing with here is 'wingnet.net', which you'll see from the trace 4s
below.
Let's just focus on one user: swbates.
This user is NOT listed in our 'users.filter' file, so it falls through
to the DEFAULT, which is blank. So the 'users.filter' AuthBy FILE returns
ACCEPT, which is again visible in the trace 4 below, and is exactly what
we want.
Now, this user has a Simultaneous-Use check item in our 'users' file here:
swbates Simultaneous-Use = 1, Auth-Type = System
Idle-Timeout = 1200, Session-Timeout = 10800
I've tried putting the Simultaneous-Use in front of and behind the Auth-Type
(I read somewhere that in front of is better, and we were placing it behind)
but the result is always the same: It doesn't work.
So this user should NOT be allowed multiple simultaneous logins. However,
my pmwho command to my TotalControl terminal server reveals that he is
indeed logging in twice:
# hawho mega | grep swbates
Sba swbates 206.30.62.93 Netwrk In ESTABLISHED 49 0
Sci swbates Netwrk In ESTABLISHED 47 0
And here are the two trace 4 debug authentication logs (minus the user's
password):

Radiator says above that it deleted the session, which I'm thinking is probably not
good. However, I don't know why it did that. Also, I have never seen anything stating
that Radiator is actually using the pmwho program I set up. Before, when I was trying
to get the snmpget program working with TotalControlSNMP it at least showed the snmpget
command being executed (but the command failed for some reason, so I'm back to using pmwho).
Hopefully you can tell me what the problem is. Basically, at this point I'm wondering
two things:
1.) Why isn't Radiator tracking sessions and honoring Simultaneous-Use properly?
2.) Why isn't Radiator using my pmwho command (hawho)?
Thanks for all the help!
