How to create an alias for linux server name?

  • 772

The openSUSE server name is 'darkhelmet'. I want to create an alias 'dh' for it. So I can also type 'ssh dh' and 'http://dh' would work too.

What file/files and where do I have to edit to make this happen?

Extract from /etc/hosts from darkhelmet 

127.0.0.1       localhost

# special IPv6 addresses
::1             localhost ipv6-localhost ipv6-loopback

fe00::0         ipv6-localnet

ff00::0         ipv6-mcastprefix
ff02::1         ipv6-allnodes
ff02::2         ipv6-allrouters
ff02::3         ipv6-allhosts
127.0.0.2       darkhelmet.edumate darkhelmet
10.0.0.22       db2workgroup db2workgroup

[root][skroob] nslookup darkhelmet

Server:     10.0.0.10
Address:    10.0.0.10#53

Name:   darkhelmet.edumate
Address: 10.0.0.22
linux opensuse hostname

    Your nslookup would indicate that 10.0.0.10 provides a DNS server. Do you have access to it? If not, then unfortunately you're out of luck.

    Since you don't have access to the server, you'll need to ask the admin to add this entry to the zone file (or one to this effect):

    dh.edumate.    IN CNAME darkhelmet.edumate.

    Assuming that you (all) have search edumate in your /etc/resolve.conf.

    I'm going to leave this previous answer for reference, otherwise this entire process won't make too much sense to others:

    I am assuming you have at least 2 machines.

    1. darkhelmet
    2. All the other other ones that need to connect to darkhelmet

    In this case, you need to edit /etc/hosts on the machines that you want to connect to darkhelmet on (but you can also do this on darkhelmet if you want it to be able to connect back to itself as dh).

    e.g.

     1.1.1.1    dh

    where 1.1.1.1 represents the IP that darkhelmet has. That way ssh dh and http://dh/ will work as expected.
