I've created a SQL statement to select as old sessions and would like to
share for reviews.

SELECT
b.radacctid,b.username,b.callingstationid,b.acctstarttime,nasipaddress FROM
radacct b WHERE b.acctstoptime is null and b.acctstarttime < (SELECT
max(c.acctstarttime) FROM radacct c WHERE c.acctstoptime is NULL and
c.callingstationid=b.callingstationid and TIMEDIFF(now(),c.acctstarttime) >
'1:00:00')

Basically the SQL statement above selects all open sessions with more than
one occurrence and even mac address with session start more than 1 hour.
Is this effective? Is there any other situation you should anticipate?

Regards,
