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!
