i'm having trouble configuring networking on a dell optiplex 280. the os i'm trying to install is RHEL4. i've tried configuring a static hostname and networking configuration manually by editing /etc/sysconfig/network /etc/sysconfig/ifcfg-eth0 /etc/hosts /etc/resolv.conf. i've also wiped the machine and entered the required network information in the graphical install. the result is the same: i can't ping out to google.com or an ip address.

i've also tried configuring the machine as dhcp instead of static ip and hostname - the result is the same, no network connection.

i've verified that my port works - i take the ethernet cable and plug it into my laptop and it works.

i've double checked my network settings, they are identical to a known working system.

eth0 shows up in the rhel graphical install, so i'm assuming my card is supported. my card is Integrated 10/100/1000 Network Card on a dell optiplex gx280. the redhat hardware site is down so i couldn't confirm this. this is a pretty standard hardware setup, so i'm fairly certain the card is supported.

are there any sites to configure networking on rhel4? i've been using the rhel4 manuals. is there anything else i should check?

Do a ifconfig and post the reply in here

The ifcfg-eth0 you need to manually edit should be /etc/sysconfig/network-scripts/ifcfg-eth0.

On my CentOS4 and FC4,5 setups, there is no /etc/sysconfig/ifcfg-eth0. There are several ifcfg-eth0 used by the gui network config that are not linked to the network-scripts one. They make manual configuration very confusing.
