Do you have firewall running on your local box? Perhaps Red Hat 8.0
comes with one installed - I bet it does. If so, either just turn
your firewall off, or configure it to allow incoming to the port you
have AOLserver listening on, port 8000 in your case.
There are lots of old posts about firewalls and stuff, try searching
in the Forums. In fact yes, this
thread from June
says Red Hat 8.0 uses a firewall called "lokkit", so that's probably
your problem.
