Accepted Answer

Add the following line to your hosts file /etc/hosts

127.0.1.1 machine02.domain_name.net machine02.domain_name.net

And in your /etc/hostname file, change the hostname to

machine02.domain_name.net

You also need to have an A record for machine02.domain_name.net pointing to the server IP address.
