set REMOTE_HOST to a subnet?

[eusmark]

This is a fantastic project. I have a need to have the --listen flag able to receive connections from a subnet that is dynamically setup. For example "--listen 10.111.25.0/26".

Hi Mark - appreciate the feedback.

I'll merge the code that will do this in the next few minutes.

Thank you so much for the quick response and fix!

I just tried it out and getting an exception. This appears to be a python3 vs python2 syntax issue. Will see if there is a quick fix, otherwise, will install python2 on this system.

Fix pushed - sorry about that.

[eusmark]

Just tested and works like a champ! Thank you!

[eusmark]

Will this continue to work on python2 as well?

[alsmith]

Can you give it a try... I took the plunge a while ago:

multicast-relay> python2 ./multicast-relay.py 
zsh: correct 'python2' to 'python3' [nyae]? n
zsh: command not found: python2
multicast-relay> 

[alsmith]

But basically if it worked on python2 yesterday, it will still work today.
