User never get disconnected (was Re: Simultaneous-Use problem)

[Jacob Jarick]

for a temp fix I would make your perl script ping said ip before
checking for idle (perhaps a sleep timer) or you could simply have
each supposed active ip pinged every 1 - 2 minutes by a seperate perl
script.

Would you mind posting your checkrad.pl script, Im a perl hacker myself :)
