hostname --fqdn returns only hostname

[altiris]

Whenever I issue the command "hostname --fqdn" I only get the hostname of the machine, rather than getting the hostname and domain name. Why is this? I have already edited my hosts file to have "127.0.0.1 my-pc my-pc.mydomain.com my-pc" without the "". I have also put the correct FQDN in /etc/sysconfig/network. Is there something else that I am missing?

Yes, your hosts file entry is wrong. It needs the fqdn as the first thing after the ip address.

(Let say my hostname is PC1 and domain name is computer.com)
The first time I tried it like this "127.0.0.1 PC1.computer.com" and when I try the command "hostname --fqdn" I get unknown host. Then I tried "127.0.0.1 PC1.computer.com PC1" and now when I do hostname --fqdn it returns the correct fqdn. Thank you for help, I hope this helps others.

What do you have listed for your "HOSTNAME" in /etc/sysconfig/network ?

If the machine has a static IP address put this address and the FQDN in /etc/hosts, not on the localhost line.

is it okay if my hosts file also has this (below), or should I comment those out?

Code: Select all

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

Those are correct and necessary.
