Online Status & SQL

[Gunther]

Hi,
What is the second easiest way to know who is online beside radwho when
using
FR & MySQL. The radacct table seems to be the only place. Will it be
sufficient
just testing if AcctStopTime is 0? I saw some 'old' sessions in the table,
which
have AcctStopTime = 0 and no terminate cause. These 'zombies' would have to
be
cleaned by a watchdog ... (Note: Zombies were left under FR 1.0.4, now I'm
on 1.0.5 and no zombies so far).
Am I on the right track here?
Thanks!
