I have a virtual server running Debian Squeeze. I can change the hostname by running the hostname new.host.name command or by editing /etc/hostname and then running /etc/init.d/hostname.sh, but after a reboot the hostname will be reset to the preconfigured hostname chosen by the server-hoster.

Before the switch to systemd, I was able to ssh between my two machines via user@hostname but now I get a "could not resolve hostname" error and have to use the IP address instead.

what is the difference between smitty mktcpip and smitty tcpip ?

Also anymore steps to follow or just updating using smitty is enough (hoping that no reboot is required)

Also below is the proce

I have several Amazon EC2 servers and I'm using Chef to manage the configuration. I'd like to set the hostname so that the default bash prompt is more helpful.

Right now after launching a new server it's just set as:

root@ip-10-123-123-123

Since I'm using Ubuntu 12 on these boxes I consulted the corresponding man page for hostname.
