I have never understood Arch's approach to properly setting a FQDN on a server. According to the Wiki...and I will quote:
"Add your hostname, coinciding with the one specified in /etc/rc.conf, as an alias, so that it looks like this:
127.0.0.1 localhost.localdomain localhost yourhostname
If you use a static IP, add another line using the syntax: <static-IP> <hostname.domainname.org> <hostname> e.g.:
192.168.1.100 yourhostname.domain.org yourhostname"
Now this does not work for me and maybe I am not understanding this but my server hostname is "mail" and it will be managing a domain called "iamghost.com" so I need my output of the command 'hostname -f' to result in 'mail.iamghost.com' and when I follow the guide, that is not what I get.
Obviously my server has a static IP so I followed the Wiki as shown below:
#<ip-address> <hostname.domain.org> <hostname> 127.0.0.1 localhost.localdomain localhost mail 10.1.1.200 mail.iamghost.com mail
The above gives me the correct output when I run the 'hostname' command = 'mail' but when I run the 'hostname -f' command, I get localhost.localdomain. This will cause severe failures in MySQL and Postfix. Not to mention all my certificates I self sign / generate will not have the proper info. Can someone please explain to me why this does not work for me? Normally in distributions like CentOS, Debian, Slackware, etc etc etc...I am able to just enter a hostname and domain name for the system.
Thanks!
Add this 127.0.0.2 mail.iamghost.com mail
