Dynamic DNS on FreeBSD and NoIP.com

no-ip is the only free dynamic IP address provider that provides a client for FreeBSD (or to give credit where it is due, that some kind volunteer ported to FreeBSD).

Regardless, the service works and I have no complaints, other than forgetting how to set it up when I build a new server. So here, for my reference, is how to set up the client on FreeBSD.

  • Create an account on no-ip, then create a domain (either pay to register a domain, or use one of the free ones available).
  • Update your ports tree, then build and install the client. I found you can install the binary using pkg, but the only way to create the binary configuration file seems to with the port. 
    % cd /usr/ports/dns/noip/
    % sudo make install
  • Create the client configuration file.
    % sudo make conf
  • You will be prompted for your no-ip username and password, network interface and hostname (say No when asked if you want to update all your hosts, you’ll then be prompted for each of the hostnames you have registered (fwiw, the configu file is /usr/local/etc/no-ip2.conf).
  • Edit /etc/rc.conf to start noip at boot.
  • Start the noip service.
    % sudo service start noip service status noip

  1. I had to update “/usr/local/bin/noip” with the following:


    . /etc/rc.subr


    : ${noip_enable=”NO”}
    : ${noip_config=”/usr/local/etc/no-ip2.conf”}
    : ${noip_user=”noip”}
    : ${noip_group=”noip”}

    # Added

    load_rc_config $name

    eval “${command} -c ${noip_config}”

    eval “killall -TERM noip2”

    run_rc_command “$1”

    1. Thanks Deamon for the update. I haven’t been using the DDNS service myself recently. I still happily use No-IP for DNS, but my IP provider hasn’t changed my address in years and at some point after a server upgrade I forgot to reinstall the noip client. It might help though that I’m using a residential cable service and also haven’t moved in years. Cheers.
