Hmm, I am grasping at straws here, but it seems that perhaps you are the
victim of somebody hacking in to your system. You realize that whenever a
Unix system is on the Net (via PPP or whatever) outsiders can telnet in, FTP
in, etc. unless you specifically disable those services.
If you don't have good passwords set, this could be the problem. You may be
the victim of a a "fork bomb" which basically takes up so much CPU processor
time and swap space that everything else grinds to a halt...and it would be
possible for such a thing to cause a logout (the behaviour of *any* OSs when
all resources are maxed out is generally unpredictable). First thing you need
to do is make sure that nobody has access to crontab and that you are not
running the "at" program (which can let people run these nasty things at
various scheduled times.) Then you will probably want to disable allowing
incoming telnet, rlogin, rsh, ftp, and finger connections. You can do this by
editing /etc/inetd.conf file.
Now I may be totally off on this and it could be a different problem. As I
said, I am grasping at straws. But it won't hurt you to make your system a
bit mroe secure anyway :-)
