Permanently add static IP and default gatewayJuly 2, 2006
Red Hat Linux has made it fairly easy to set up network so that it will start automatically. There are a series of scripts in /etc/sysconfig/network-scripts that will do most of the work.
1. Binding IP address
In “/etc/sysconfig/network-scripts/ifcfg-eth0”, add your IPADDR (IP address), NETMASK, NETWORK and BROADCAST address
DEVICE=eth0 ONBOOT=yes IPADDR=192.168.0.x NETMASK=255.255.255.0 NETWORK=192.168.0.0 BROADCAST=192.168.0.255
2. Adding Default Gateway
In “/etc/sysconfig/network” add your default gateway.
You can now restart your network:
#/etc/sysconfig/network-scripts/ifdown eth0 #/etc/sysconfig/network-scripts/ifup eth0
( please dont run the command remotely.. else you may have shutdown the interface and will be disconnected )
or in redhat:
#service network restart
# /etc/init.d/network restart
Check your “/sbin/route” (routing) to verify everything is in place and restarting your computer should hold your new settings.
