I have a printer queue shared from a desktop running Mint, with the hostname of server and a local dns name of server.home.

I have a Ubuntu laptop which I want to connect to that shared queue. Using the GUI, I can find the queue on server.home, and the printer icon appears as expected in the printer list. For some reason though the printer is built with a device URI referencing server.local.

I can change it back to server.home and the printer works correctly, but the device URI for the printer queue gets changed back to server.local whenever I restart the laptop.

I can't find any reference to a local domain anywhere - I have check /etc/hosts on both machines, and the DNS records (name lists on the Home hub config).

Where else should i look, because I would rather not have to reset the URL name every time ..

  • Not sure how CUPS reverse resolve IP to name. But I expect this is related to Avahi (mDNS) which uses .local domain. The global host name resolving setup is in /etc/nsswitch.conf, If you have something like: hosts: files mdns4_minimal dns [NOTFOUND=return] mdns4 then try changing it to: hosts: files dns mdns4_minimal [NOTFOUND=return] mdns4 so dns comes before mdns.

  • I don't use Avahi - I will double check if Mint has installed it for some reason.

    I found `/etc/nsswitch.conf' on both server and my laptop - i have done the edits - and i will check if it made an impact on the next restart

    @user.dz - if you want to make your comment into an answer - I will click it as accepted, and give you the bounty I posted. I have restarted both the server and the laptop - and reconnected to the printer queue, and the host name is being reported correctly now. Thank you.

The only service I know using .local domain in Linux is Avahi/Bonjour (mDNS) but not sure how CUPS reverse resolve IP to name.

  1. Check the global host name resolving setup is in /etc/nsswitch.conf

  2. If you have something like:

    hosts: files mdns4_minimal dns [NOTFOUND=return] mdns4

    then change it to:

    hosts: files dns mdns4_minimal [NOTFOUND=return] mdns4

    So DNS comes before mDNS. See man nsswitch.conf for reference.
