You need an ifcfg-eth0 file in a directory under /etc/sysconfig/networking/profiles/... probably "default" would be the directory name you want. The file will look something like this: # Broadcom Corporation NetXtreme BCM5705M Gigabit Ethernet DEVICE=eth0 HWADDR=00:0F:1F:C9:C3:A7 BROADCAST=192.168.0.255 ONBOOT=yes TYPE=Ethernet USERCTL=no PEERDNS=no IPV6INIT=no NETMASK=255.255.255.0 IPADDR=192.168.0.88 GATEWAY=192.168.0.1 You might already have such a file on your system. In fact, you should have one for each NIC... at least. Of course the last variable, "GATEWAY", is used to specify the default route. hth, ken -- Find research and analysis on US healthcare, health insurance, and health policy at: <http://healthpolicydaily.blogspot.com/>
