[SOLVED] How to set-up hostname?

dbsput · 09-22-2011, 11:38 PM

I am trying to install iRedMail on a freshly installed Debian Squeeze server but I am instructed to add a fqdn in order for iRedMail to install.

My /etc/hosts currently looks like:

Code:

127.0.0.1     mail.mydomain.com localhost localhost.localdomain
184.XXX.XXX.XXX     mydomain.com

My /etc/hostname currently looks like

Code:

mail

This is what I best gather from what the tutorial states on this page.

I have tried many combinations and run /etc/init.d/hostname.sh many times but can't seem to get it right.

Can anyone offer a solution?

Edit: I forgot to mention that when I test the set-up with `hostname -f` I receive the error

Code:

hostname: Name or service not known

I'm not a expert on this, but have you tried entering following line in to etc/hosts
Your_server_ip_address(local) server_host_name.domain_name server_host_name
Ex: 192.168.10.20 sapprdsvr.cblf sapprdsvr
also change the 127.0.0.1 mail.mydomain.com localhost localhost.localdomain to 127.0.0.1 localhost

take a backup of current host file before changes.

Also you can change the hostname temporaly using the command hostname.

Your hostname needs to be like this:
mail.somedomain.com

This needs to be added to /etc/hostname and to /etc/hosts.
