Specify subnets rather than interfaces? about multicast-relay HOT 6 CLOSED

Sure thing - I’ll get to it shortly...

from multicast-relay.

Just checked in code to do this... have a go and see how you get on...

Excellent thank you.

Ran:
./multicast-relay.py --interfaces 192.168.0.0/24 192.168.1.0/24

Got:
Interface 192.168.1.0/24 does not exist.

This Ubuntu Linux box only has one NIC and only one interface configured. While it can access both subnets, it's interface is only through the primary 192.168.0.0/24 subnet.

Might not be possible in a machine with only one interface.

I suspect that if you have just one interface that you're using interface aliasing to assign the second IP#... if you could paste the output of this, I can verify and might be able to work around the issue for you.

cut -f1 -d: /proc/net/dev

Ok, I checked in some experimental code to https://github.com/alsmith/multicast-relay/tree/one_interface - let me know how you get on. Do be mindful that you might cause a broadcast storm that'll bring your network down... but hey give it a try!

Oh and you'll need to just specify the single physical interface and also add --one_interface, like this - no need to specify each network separately by IP address.

./multicast-relay.py --interfaces en0 --one_interface --foreground --verbose
