Hello, I have a FreeRADIUS server doing authentication and accounting with ADSL and with wireless users. The wireless users are connected to a MikroTik which is running a PPPoE server. There are absolutely no problems with the ADSL users, but the PPPoE users are constantly losing their connections and then reconnecting. En average, the length of sessions varies between 1 and 10 minutes and most times shows "Acct-Termination-Cause = User-Request". I've checked the status of the wireless link but everything seems to be right. There are other wireless users in the same neighbourhood and some of them have this problem and others do not. Thank you very much for any suggestions you can provide. -- View this message in context: http://freeradius.1045715.n5.nabble.com/Problem-with-FreeRADIUS-PPPoE-Mikrot...

I don't see anything related with freeRadius... On 11/23/2010 10:25 PM, Pableus wrote:

I was wondering if there is any FreeRADIUS setting I can configure/modify to avoid this problem... Thanks again -- View this message in context: http://freeradius.1045715.n5.nabble.com/Problem-with-FreeRADIUS-PPPoE-Mikrot... Sent from the FreeRadius - User mailing list archive at Nabble.com.

Broken MikroTik? No, it's a RouterOS running in a X86 HP server, which is currently handling about 1500 PPPoE clients. Now we are migrating the authentication process to a RADIUS and these problems appear. -- View this message in context: http://freeradius.1045715.n5.nabble.com/Problem-with-FreeRADIUS-PPPoE-Mikrot...

It 's problems on Mikrotik . How many PPPoE Client online before terminated occure?
I have not got the exact number right now. We're still doing tests, so for now a few clients authenticate with RADIUS, the rest follows as usual. What catches my attention is that users only have problems when they are passed to the RADIUS, otherwise do not have problems with disconnections. -- View this message in context: http://freeradius.1045715.n5.nabble.com/Problem-with-FreeRADIUS-PPPoE-Mikrot...

show your ppp log.

What you are saying.... My red car wont drive, but my green car does. What is wrong with my red car? We have NO IDEA. You will have to troubleshoot yourself and come up with better info. Cheers, -- Johan Meiring Cape PC Services CC Tel: (021) 883-8271 Fax: (021) 886-7782

What catches my attention is that users only have problems when they are passed to the RADIUS, otherwise do not have problems with disconnections. Have a look at three things..
1. When does the error occur, immediately after a PPPoE service restart, or the Mikrotik is restarted? We've noticed that if the service is stopped, Mikrotik doesn't send all the Disconnect packets, so you can have IP mismatches, and other issues which really aren't the fault of the Radius server. 2. Have a good look at your wireless log, and try talking to some of the clients who have the issue, it may be a CPE problem, or maybe they just have a crappy signal. 3. Look at things like Idle Timeouts, and see if your NAS has any errors like Radius Timeout.. 4. As an aside, if you're doing 2.4 GHz, you could just be subject to DOS issues..
But I still don't understand why the termitation cause is, most of the times, "User-Request". -- View this message in context: http://freeradius.1045715.n5.nabble.com/Problem-with-FreeRADIUS-PPPoE-Mikrot... Sent from the FreeRadius - User mailing list archive at Nabble.com.

"User-Request" is sent by the CPE is almost all cases unless there is a fault with the connection between the CPE and the NAS. This is not a radius issue. Regards Wayne
That's what I figured too, but why only happens when I move the authentication process from the MriktoTik to the RADIUS?

If you insist that this is a Radius problem and not a MikroTik config problem, you'll need to at least show us the Radius debugging from the MikroTik. Do this to enable Radius debugging: /system logging add topics=Radius Now wait for one of your users to connect and then drop again, and do this to see the log: /log print Gideon
