I just set up RedHat 8.0. Everything works fine with the network connection (I'm using the box to make this post right now), unless you're trying to access it remotely.
I can't telnet, ftp, or even ping the box from another machine using the hostname. If I look up the IP address in the router (it has built in DHCP) it doesn't have a hostname listed for the address, the field is just empty.
I can ping the IP address and get a response, so things aren't totally hosed. I've never this problem before. I always just set the hostname and all the other machines could see it. What'd I screw up?
my /etc/sysconfig/network:
NETWORKING=yes
HOSTNAME=ghoul.localdomain
My ifcfg-eth0:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=dhcp
USERCTL=no
PEERDNS=no
TYPE=Ethernet
