I have Ubuntu Server 8.04. I use to have the hostname oldhostname and url oldhostname.whatever.com. I am changing hosename to newhostname by following the instructions

http://codeghar.wordpress.com/2007/1...ame-in-ubuntu/

So, I changed the hostname in both /etc/hosts and /etc/hostname and restarted /etc/init.d/hostname.sh, but my server still loads the webpage at oldhostname.whatever.com instead of at newhostname.whatever.com. Typing hostname at the prompt yields "newhostname" for the current hostname.

The instructions above use /etc/init.d/network. I only have /etc/init.d/networking. I don't know if there is a difference in the two. I ran that, but nothing changed.

Any suggestions?

Thanks.

You need to change the DNS records. Do you have administrative control for your domain name on the name server?

I am the administrator on the machine that I am trying to change the hostname, but I have no control over the whatever.com part of the url or any of the DNS servers. I only have control of the hostname. I am on a network, though, and it does seem to recognize that I have a machine with the initial hostname. I initially set up this server with the hostname oldhostname without having to talk with the people running the DNS servers. The network just worked with me and allowed oldhostname.whatever.com to reference my server.

DNS maps a name to an IP address not a hostname. For example compare the output of these two commands:

dig oldhostname.whatever.com

dig newhostname.whatever.com

More than likely you will see an 'A' record for oldhostname.whatever.com but not for newhostname.whatever.com. Of course you would have to replace those with the actual names you are trying to query.
