Multipass NetListener

Multipass NetListener is a LaunchDaemon that remove hostfilter on MacOSX default bridge for each vm.

You should be use it, if you add multiple network addresses inside your multipass vm. By default, Mac osx use L2 Filtering on bridge (man ifconfig @hostfilter).

Thank to @yadel for network hack !

You can see it with the following command:

ifconfig -v bridge100

#output ( see hostfilter )
  ...
        member: en3 flags=3<LEARNING,DISCOVER>
                ifmaxaddr 0 port 7 priority 0 path cost 0
                hostfilter 0 hw: 0:0:0:0:0:0 ip: 0.0.0.0
        member: en4 flags=3<LEARNING,DISCOVER>
                ifmaxaddr 0 port 12 priority 0 path cost 0
                hostfilter 0 hw: 0:0:0:0:0:0 ip: 0.0.0.0
