It would help for the ones that do. ----- Original Message ----- From: TDE Internet To: [EMAIL PROTECTED] Sent: Thursday, May 20, 2004 11:54 AM Subject: [VOPRadius] "Ghost users causing simultaneous login limit exceeded" (wholesale ports) At 11:19 AM 05/20/2004 -0400, you wrote: All VopRadius users,   I'm working with Sylvain Savignac at Vircom on this issue.  The problem is that most wholesale ports providers do not provide support for watchdog packets between the NAS and your radius which means there is no process in place to reconcile the list of users actually online.  If the NAS restarts or otherwise is unable to send the stop packet to radius the user ends up with a ghost record in radius.  When the user tries to log back on if you have port-limit = 1 the user is rejected based on simultaneous login limit exceeded.  This operational issue is not going to go away unless a creative solution is implemented.  In my opinion just such a solution was suggested some time ago on this mail list.  The recommendation is as follows: " if the calling station-id was stored with the rest of the users information in the online users table in radius, a ghost user could be cleaned up when they try to reconnect from the same phone number."  The assumption is that it would not be impossible to be simultaneous from the same originating number.   I would appreciate feedback from others on this list with thoughts on this solution.   Thanks, Steven Bastardi The Home Town Network Inc.   Doesn't do any good for users who have their phone number blocked.  At least 1/2 of our customers don't show any dialed from phone number.

Now this brings up a question I hadn't thought of before:  Can VOP perform the same logic (i.e. check the called-from number, and if it is the same as the active session, allow the user to log in)?  This would also provide us with a fix. Given that at least two of us are dealing with this, I'd be most appreciative if someone from Vircom wouldn't mind weighing in on this.  Otherwise, I'll contact support.

They have a "good" ghosting policy, verify not only by your radius, but by the number the person is calling from, and can knock off a ghosted user, to allow the same person back on from the same number, but not a different number. They also give the user the benefit of the doubt until it is shown he is an "ab-user". As to wrong passwords, unless that is a  caching issue, I don't know about that.  (They do caching, so if they can't reach you, they can still allow your users on line.)

I just checked my logs and they customers are being logged. High Speed Internet at it's Best Gene DuCharme Owner Inland North West Internet 401 S.

I have client definitions setup and have tried with �other� and �Radius Server� and authentication is working however, I get no radius errors when a bad login is used, nor do I get an entry in onlineusers when a good login is used and gets connected. Also, does globalpops pass on stop packets for users they detect as a ghost � or am I going to have ghost issues with them?
