Unable to set Network in RHEL 6.4

I am not able to get ip in RHEL machine, It only works when i run command

sudo dhclient eth0

I am new to RHEL i am not able to get this. I have tried below command to come to this above solution, But i want it automatic.

# ethtool eth0

or

# mii-tool eth0

I used above command from stack overflow answers to find which link is actually up and i found it is eth0

but on my machine below are there

/etc/sysconfig/network-scripts/ifcfg-eth1

Contains entry for DEVICE=eth1

i manually changed all these to file eth0 and DEVICE=eth0

Still it is not working

Solution

  • I found the way out of this

    i run command sudo dhclient eth0 then i got network to make it permanent i used ifconfig for getting mac address for it and then updated mac address in /etc/sysconfig/network-scripts/ifcfg-eth0 and its done
