Any difference to set in /etc/hosts & /etc/sysconfig/network ?

Plan to set my hostname in my linux centOS.

Should I set in /etc/hosts or /etc/sysconfig/network ?

Any difference to set in both place?

You really should set it in both places, just because that's
where distros using that system place it on installation by
default. That said: /etc/hosts is mostly relevant for "local"
use on the machine.

Hi Casualzone,

If you want to set hostname, I suggest you to set in following way.

Code:

# sysctl kernel.hostname=your.hostname.com

You can also set in /etc/hosts and /etc/sysconfig/network, But many times it will not be reflected in all the places.

After setting the hostname as specified above, you can check it using

Code:

hostname

Cheers !!

/etc/hosts is used by programs to look up hostnames (think of it as local dns), such as most daemon processes.

/etc/sysconfig/network- is what the system uses to set the hostname.
