Dial-up connector..

Ok, newbie alert!!

A friend of mine has that out-of-the-box Linux firewall installed at his
home (Net-something-or-other....). He's pretty computer savvy but not with
Linux. I am nearly a complete newbie, but know more than he does (a scary
thought)...anyway, here's the problem...

I indicates the product has a dialup connector and he has it set for auto
redial in case of disconnection. I guess it connects ok manually, but
doesn't redial like it's supposed to...he gets error messages saying
something is wrong and that a log-file is being created.

He figures he can debug it IF he can find the log file.

Any ideas on the path to this mysterious log-file??

TIA,
Tim
