RE: Devices created automatically

My guess would be Nimba type virus trying to get to your machine.  Looking
at the logs of our IIS web server, we get tons of errors for variations on
CMD.

QUIT is a common command for Telnet type clients such as FTP (Port 21),
Telnet (Port 23), SMTP (Port 25), POP3 (Port 110).  My guess is there is
one, or more, infected clients out on the internet set up to scan for open
Telnet ports, and they keep hitting yours, don't get a response, so issue a
QUIT command which the AS/400 takes as a user name.

With these Nimba type viruses it's no longer a matter of if someone tries to
hack in, but how often.

One thing I used to do on my Mail server, when I was hit by a spammer (our
mail server was old and wouldn't allow me to disable mail forwarding) I
would enter a route for their IP address with a default gateway of 0.0.0.0
(an invalid IP address).  So when they hit my mail server, my mail server
would try to respond to 0.0.0.0 and it wouldn't go through, and they were
effectively blocked.
