Redhat network interface configuration

Posted by Vivek on Wednesday March 29, 06 @3:47 pm

Redhat Linux network interface names start with ethX. First Ethernet network interface name is eth0, second is eth1 and so on.

$ su -

To list or display more information about network interface type command:

# ifconfig | less

To assign an IP address type following command:

# ifconfig eth0 192.168.1.1 up

To take down network interface type following command:

# ifconfig eth0 down

To configure network card using GUI tool type command:

# redhat-config-network

You can also type command setup and select network configuration from menu:

# setup

If you wish to configure network interface manually then you need to edit files stored in /etc/sysconfig/network-scripts/ directory. For example here is my sample /etc/sysconfig/network-scripts/ifcfg-eth0 file for eth0 network interface:

DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.1.255
HWADDR=00:0F:EA:91:04:07
IPADDR=192.168.1.111
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
TYPE=Ethernet
