For anyone with this problem in the future.
Your hostname is taken from your network script, which may vary on your OS.
I use RedHat, and Fedora. My host name is not set it /etc/hosts. That is what is used for a reference from IPs to logical names.
Fedora and RedHat users, your host name can be changed in /etc/sysconfig/network.
Then to change it for now without taking down your network:
# hostname name.domain.suffix
I do not know what network manager will do to this host name, if anything. I do not use network manager myself.
Before continuing don't forget to shutdown sendmail, and apache 'httpd'. |
