This is, of course, how to set IP addresses from the command-line.
If I can't configure it with a CLI then I don't want to know how to do it.
How to permanently set static IP in Ubuntu
Edit the file:
/etc/network/interfaces
Edit the section for your primary network interface. It is probably device eth0 or eth1. Say you're on a 192.168.1.0 network and you want to set your static IP to 192.168.1.66. These values are typical.
auto eth0
iface eth0 inet static
address 192.168.1.66
network 192.168.1.0
netmask 255.255.255.0
gateway 192.168.1.1
broadcast 192.168.1.255
How to set static IP in RedHat
All network config files are in this directory:
/etc/sysconfig/network-scripts
Each interface will have its own file named after the infterface:
ifcfg-eth0 ifcfg-eth1
The contents of a minimal ifcfg-eth0 file looks like this (GATEWAY may not be needed if you are just setting up a LAN between a few machines):
DEVICE=eth0 ONBOOT=yes BOOTPROTO=static IPADDR=10.1.0.1 NETMASK=255.255.255.0 GATEWAY=10.0.0.1
