This is a "set and forget" solution for people who want multiple .local addresses without the joy of them breaking every time their laptop sneezes and switches Wi-Fi networks.
a. With make install
- Run
make install - ???
- Profi.... wait it's free fucking software damn it!
b. With a debian package because of course I provide one
- Build the package with
make deb-pkg - Install the resulting .deb using apt or dpkg or whathever you want to use
sudo systemctl enable --now avahi-alias@look-ma-no-ips.localUsually you also have to allow port 5353/udp if you have a firewall enabled.
Not every firewall completely blocks mDNS traffic but you should assume that it does and explicitly add a rule to allow mDNS traffic on your desired network.
