Hi,
How do I configure a network card from CentOS Linux command line?

TIA

I do not know in CentOS, but it should still be there, you can use 'ethtool'

'man ethtool'

You can use the -s swith to set options for your nic.

Hope that helps.

hi there,

To configure your network card on centos via command line you enter the commando: "setup"
Or you can edit the file: /etc/sysconfig/network-scripts/ifcfg-eth0

Regards,

yup, setup is great tool.

Hi All,

if you want to configure ur network card in a single command line,

do the follow,

#ifconfig eth0 192.168.0.1 netmask 255.255.255.0 (For 1st card)
#ifconfig eth1 192.168.0.2 netmask 255.255.255.0 (For 2nd card)

[OR]

#ip addr add 192.168.0.1 dev eth0
#ip addr add 192.168.0.1 dev eth1

Note:

keep in mind that, if u r using the above command it ll take immediate effect on kernel.

if u r using netconfig (or) setup utility it ll only overwrite the /etc/sysconfig/network-scripts/ifcfg-eth0 file.Then , after that u have to restart the network service like follow,

#/etc/init.d/network restart

But in ip & ifconfig command not like that.please go through the manual page of ip & ifconfig command.Most of Distro doesn't have netconfig (or) setup tool, which one presantly Redhat Have.

thanks,
