I want to assign a static IP address to eth0? I'm using Red Hat Enterprise Linux 3 AS.

You should be able to do it by changing the file /etc/sysconfig/networking/devices/ifcfg-eth0

mine looks like this :

DEVICE=eth0
BOOTPROTO=none
HWADDR=[Your mac address]
ONBOOT=yes
TYPE=Ethernet
IPADDR=192.168.0.10
NETMASK=255.255.255.0
NETWORK=192.168.0.0
USERCTL=no
PEERDNS=no
GATEWAY=192.168.0.1

You'll juste need to restart the "network" service after that

you could also get a more "grafical" interface to configure the static IP of your eth0 :
LINUXCONF it's a great program that allows you to adjust MANY settings concerning servers, clients, administration of your system and many other things.

take a look at your rpms. .. it's built in dialog boxes...

I want to be able to install multiple static ips.

I have the range 214.242.152.2 - 214.242.152.14.

How do I go about doing that? Using Fedora Core 1.

You will need to set up aliases. The way I understand it, the "main" ip goes in

/etc/sysconfig/networking/devices/ifcfg-eth0

A secondary ip would go in /etc/sysconfig/networking/devices/ifcfg-eth0.0

etc....
