FQDN? Attempting to set up server for first time...

**infallible** · February 13th, 2009

After using ubuntu 8.04 amd64 for a while, I've decided to incorporate some server functionality into my system, mostly following guides and howto's because of my ignorance. I'm starting out with a postfix mail server based on this http://flurdy.com/docs/postfix/ guide, and I keep encountering notifications about the "fully qualified domain name" and "ServerName". How do I set this up? It seems like I should do so before I continue too far. I'm also not sure when (or how, but I'll get to it when the time comes, i suppose) I should point my domain name towards my server via GoDaddy's stuff. Can anyone help out a guy who is so new to the server game?

Hi
I think that you might get your hostname by running "hostname" in terminal.
The FQDN is the URL that u use when connecting to your server from Internet. eg. mail.yourdomain.com

Thanks, lars, but I'm not sure how to apply that information. In fact, now that I've progressed halfway into the setup of flurdy's guide, I'm not even sure what functionality I will have gained, or if I can even use it. I'm going to bail on postfix and play with apache for a while, I think.

In file /etc/sysconfig/network:
HOSTNAME=mail.example.com

Then restart networking.

In Godaddy, define the domain name mail.example.com, A, MX and PTR records. With your ISP, ensure that you have a small business server account, else port 25 will be blocked and your server won't work.

Hope that helps!

hmm...

apache is still giving me the ServerName diatribe.
there is no /etc/sysconfig/ folder.
I'm using 8.04amd64, if that makes a difference.
qwest assures me that my residential account with static IP will suffice for what little traffic I expect, but I'm not there yet...
