Re: Monitoring Tool for Freeradius

["Marinko Tarlac" <mangia81@gmail.com>]

We have a wireless network and sometimes when link between two points is down, radius updates are not received and session stays opened. I solved this problem with additional field in radacct table and I place time stamp inside that field on every update. If there is no update in 5 minutes (i can define interval), script closes connection. 

This will solve your problems with opened connections. But what if user still stays connected after link is back and his session is closed? 
Answer: Traffic won't be recorded because user don't have opened connection (session with AcctStopTime = '0000-00-00 00:00:00')

So there are no ideal solutions :)

It's guessing from the number of 'open' sessions in your accounting
database (those without a stop time), if something goes wibble on the
NAS or infrastructure between the NAS and server, and a user disconnects
in that period (and maximum retries are hit, all hosts exhausted etc)
then the Accounting Stop packet will be discarded by the switch and that
session will never be recorded as closing.

Any good administration tool should include tools to query the standard
dot1x MIB and to periodically go round and check all 'open' sessions by
polling the NAS's and ammend the information in the database
appropriately. Isn't there even a tool / script included in the FR
distro that does this ?
