On Solaris, what is a terse way to get the fully qualified domain name (fqdn) for the current host

  • 772

When I want the fully qualified domain name on Linux, I can write ...

hostname --fqdn

To get the same thing on Solaris, is it necessary to write ...

cut -f 2-3 /etc/hosts | grep ^`hostname`\t | cut -f 2

... or is there something more brief?

    From here:

    The hostname command should return an FQDN...
    ...
    The solution is to edit /etc/nodename and put the FQDN in there and reboot.

        echo foo.your.domain.com > /etc/nodename

    You might also be able to use:

    getent hosts `hostname` | cut -f 3

    or similar.

  2. Your method depends upon the /etc/hosts file being formatted in a particular way, on a S10 system I have to hand it returns loghost which is incorrect.

    If set up you can ask the DNS system with 

    dig -x your.ip.add.ress +short

    or if you are using NIS then

    echo `hostname`.`domainname`

    or you could setup /etc/nodename as Dennis suggests.

  3. Would two digs be better than one?

    dig -x `dig +short "$(hostname)"` +short

    Just be mindful of the trailing dot.
