Problem to get IP
 

Hi,
How to resolve this problem?

[root@CentOS65x64 ~]# ifconfig eth0 | grep inet | awk '{ print $2 }'
eth0: error fetching interface information: Device not found

The error is self explanatory. eth0 does not exist. Run ifconfig without any argument or pipes. You will then see what network interfaces exist.

Edit-

Try running the following instead:

[~]$ sudo ifconfig | grep inet | awk '{ print $2 }' | sed '/127.0.0.1/d' | sed 's/addr://g'

192.168.1.136

You may use dhcp client to automatically set up net if a router is connected to your box.

Thanks all.

Mralk,
Are you putting one IP to the OS?

Yes, I have only one ip address on my system. It is a laptop on wifi.
