Is it neccesary to install only the text based OS, instead of the GUI? If so, what commands do i use to edit the files that need to be edited (hosts, domain, etc). I am anything but profecient with linux, so any pointers would be greatly appreciated.

I am up to step: change the /etc/hosts file in the walkthrough, just an fyi.

*EDIT*
Sorry for the newb question. I ended up using the vi /etc/hosts in insert mode. i assume this is what everyone else uses?

Off to try and figure out what to put in this file. my zimbra server is on a local network, behind a firewall. I assume i will have to change my domain MX to my outside IP, then forward the ports to the zimbra server? Im still a little lost setting up the DNS.
