After installing RHEL 6 - Unable to setup ip address

Hi all

I started to learn redhat linux 6 , as Iam very much interested in linux os variants . Through my redhat linux 6 blog Iam here to share my knowledge , in this area , Iam not an expert but Iam learning redhat linux 6 slowly..

After Installation I tried to setup the IP address to get access with internet .. ooh I run the command " setup " from command prompt , as usual in rhel 5 the wizard open and I entered the parameters IP address , subnet mask , default gateway etc.. But Iam fed up Itz not saving the IP address details..

I read this as a BUG in RHEL 6

Here Iam Presenting the way to setup your IP Address..

Step 1

Open the following file in your favorite linux text editor

  #vi /etc/sysconfig/network-scripts/ifcfg-eth0
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
And If you want to setup your static IP edit the file like below
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

DEVICE=eth0
           IPADDR=10.10.10.10
           NETMASK=255.255.255.0
           NETWORK=10.10.10.0

GATEWAY=10.10.10.253
           ONBOOT=yes
           BOOTPROTO=none
           USERCTL=no

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

If you want to obtain IP address automatically using dhcp , edit the file like below

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 

ONBOOT="yes"
BOOTPROTO="dhcp"
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Note : If you are setup the ip address using the "setup " Command ,Change the above settings as below
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
 ONBOOT="yes"
BOOTPROTO="static"
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

After edit this please restart the services

Save & restart networking service,



#service network restart               OR

#/etc/init.d/network restart
