Overview ¶
mdns_repeater forwards multicast mDNS messages across network boundaries, allowing for discovery of devices that are L3 routable, but undiscoverable.
The device running this program must straddle the different networks involved. The program considers a set of binary relationships between networks, where one network is the "upstream" and one network is the "downstream". The "upstream" network is the one that has devices that one wants to access on the "downstream" network. These relationships are specified in yaml config file passed into the program as an argument. The file looks like this:
mappings:
- upstream: eth0
downstream: eth1
- upstream: eth0
downstream: eth2
The program recognizes network names by inteface name unless -mapDockerNetworksToInterfaces is passed as a flag in which case the program recognizes networks by their Docker names.
