Could it be possible that the error you are seeing is VOPRadius reporting
that it did not receive a RADIUS password (secret) from the ICG server? It
would make sense that VOPRadius would log this type of error in the Event
log since if the secret doesn't match, you will not authenticate anyone. I
have had tons of customers try to login with blank passwords, and have never
once seen it logged in event logs. Your statement that the ICG servers then
hammer you with a stream of requests may also point to my idea -- if
VOPRadius sends an auth reject to the ICG servers, ICG should not send you
another auth request. I would think that if VOPRadius did receive an auth
packet without the password attribute, it would still send a NAK. BUT, if
VOPRadius receives no radius secret at the beginning of the auth packet, it
will not answer the remote radius server at all since the remote radius
server has not authenticated to VOP. It seems this scenario would cause the
ICG servers to keep trying to get SOME kind of answer from you, but
continuously sending the auth packet until it, or the client, times out.

To be sure, go into the Radius control panel applet, and enable all of the
logging options including Debug level 1 and 2. Then look in your
vprerror.log and see what is really happening.... are you receiving radius
attribute 2 (Password) for these requests? Do you see the password/secret
error? If nothing else, it might give you some more insight into the real
problem if it turns out to have nothing to do with the radius secret.

(nas=170.147.40.20)



We use several different wholesale dialup network providers. One of the them
is ICG..



We have seen literally thousands of errors in our NT logs event viewer, not
in the Vop Radius error log. I have pasted the error below copy and pasted.



The only time this error occurs is when a user coming from the ICG network
tries to dialup and login with a blank password. This does not occur on ANY
other network, UUnet, Qwest, Aleron and several others.



As far as I can tell so far, ICG is not sending the password attribute when
the user sends a blank password. This seems to be what's causing the errors
in the NT Event Viewer Application log. This is also causing the end user to
get a timeout in dialup networking instead of a bad password error. So, the
user keeps trying and trying just assuming that we stink because they keep
timing out instead of receiving a bad password error.



Finally this causes the array of 30 plus ICG radius servers to keep
hammering my radius server since it received NO RESPONSE from VOP Radius. It
appears that VOP Radius just logs the fatal error in the NT Application log,
does not respond to the Radius server at all, does not log it in the VOP
Radius Error log and just DIES..



I may not be 100% accurate with all this but I think I am most of the way
there.



Has anyone else experienced this? Vircom, is there a patch or something for
this? It seems that VOP Radius is the only Radius server around that handles
the Password attribute missing quite this way.
