Change name of linux server on network

  • 772

I'm using CentOS 5. How do I change the hostname of the machine so I can ssh to it from other boxes by a short hostname? I've tried "hostname puppet", changing "/etc/sysconfig/network" and "sysctl kernel.hostname=puppet". I'd like to be able to do this without making changes to any hostfiles.

Thanks.

    You either have to setup a local DNS server or you will have to change hostfiles. The changes you did will work, only to be identified in the local system and not from other systems.
