Configuring IP to network card

I am trying to assign a static IP address to a network card using the following command:
ifconfig eth0 10.4.12.21

After the command it works fine untill the system is rebooted and then I neet to issue the command again. How do you make the IP address stick?

Most distros should have scripts configured to bring up network interfaces on start up.

Which distribution are you using ?

If your distro. has the sysconfig directory, you can edit the /etc/sysconfig/network/ifcfg-eth0 file.

On RedHat / Mandrake, it would look like this:

Code:

DEVICE=eth0

BOOTPROTO=none

IPADDR=10.4.12.21

NETMASK=255.0.0.0

BROADCAST=10.4.12.255

NETWORK=10.4.12.0

onBOOT=yes

On SuSE, like this:

Code:

BOOTPROTO='static'

BROADCAST='10.4.12.255'

IPADDR='10.4.12.21'

NETMASK='255.0.0.0'

NETWORK='10.4.12.0'

STARTMODE='onboot'

Check your distribution's documentation to get more info.

I am running RedHat 7.3. I found the ifcfg-eth0 in the /etc/sysconfig/network-scripts/ directory. This is what is in it:

DEVICE='eth1'
ONBOOT='no'
BOOTPROTO='none'
TYPE='Ethernet'
USERCTR='no'
NETWORK=10.4.0.0
BROADCAST=10.4.0.255

Should I change the NETWORK and BROADCAST lines and nothing else?
