Avahi alias systemd service
Raw
README.md

Instructions

The first file is the script to be run, which you can store in your home directory. The second file is the systemd unit file which goes in /etc/systemd/system. Make sure on line 6 it references the location of the first file, and that you run systemctl daemon-reload after editing the unit file.

To run the service automatically on boot, run sudo systemctl enable avahi-alias@[domain], followed by sudo systemctl start avahi-alias@[domain] to start it immediately.
