Hi,
Device always responds. No problems with connection nor device load. If I leave the server running user will try to login for ages, if it was a snmp connection problem, it would be able to login after some time. I have to kill server, change the nas_type to other, start server, so the user can login and server is not freezing anymore.
guess what, when you set nas_type to other, then the server is NOT trying to SNMP connect....hey, but then it works. i think the issue is quite clear.
I guess you are trying to troll me :) I'm not so stupid to see, if snmpwalk or snmget working without checkrad process :) Here are some tcpdump logs again (I cut the sensitive data from these) ......cut some unneeded interfaces .....

So I guess, there is a problem in check process on the freeradius side :) The snmp part of the checkrad script works fine. It freezes on the next step. -- Best regards, Roman.
