Issues with /etc/hosts file
 

Hi,

I have installed OEL6 in Oracle Virtualbox machine and having issues with /etc/hosts file.

I removed the host name from line
127.0.0.1 linuxrac1 localhost.localdomain localhost
and removed following line
::1 linuxrac1 localhost6.localdomain6 localhost6

but after I restart machine it pops up again. How can I solve this issue?
Due to this when ever I ping linuxrac1, it goes through ip address 127.0.0.1 (loopback).

You don't remove those lines. If you remove them entirely, you can break your system in weird ways.

INSTEAD, just remove the "linuxrac1" part from both lines. Optionally, put in a new entry for the hostname, e.g. if your static IP is 8.7.6.5, enter

Sorry if my question was not clear.
I only want to remove
::1 linuxrac1 localhost6.localdomain6 localhost6

I removed the hostname linuxrac1 from line "127.0.0.1 linuxrac1 localhost.localdomain localhost". When I reboot the system both appear again.

I found the solution. This is created by NetworkManager. After disabling the NetworkManager using folling commands I don't see this benaviour.

# /etc/init.d/NetworkManager stop
# chkconfig NetworkManager off

I have a question though. Is there any consequence of disabling NetworkManager?
