Changing Redhat Network Settings From DHCP to STATIC IP Via Configuration Files

configurationnetworkingrhel

In order to make the statically assigned IP work, I have already modified the file /etc/sysconfig/network-scripts/ifcfg-eth0 as follows:

DEVICE=eth0
IPADDR=10.33.17.143
NETMASK=255.255.255.0
BOOTPROTO=static
ONBOOT=yes

Any other configuration files that I might need to take care of before the static IP could be used? I am trying to change the network settings from the default DHCP to static IP.

You may also need to set a default route (often known as your default gateway) in /etc/sysconfig/network-scripts/route-eth0 as follows:

default via 1.2.3.4

Just make sure you substitute the correct Default Gateway for 1.2.3.4 otherwise Bad Things Will Happen... ;)
