I ran netstat after a reboot and I want to know what this is for (see: BOLD RED):

Will anything break if I block it?

[ytechie]

Yup. Canaca is the service that resolves your subsonic.org address to your public IP address. Don't block it.

I've setup dyndns... shouldn't it be safe to block it?
I don't want to use (and have not setup) https://<myname>.subsonic.org
I may block it. I don't want anything extra connecting to my machine.

[ytechie]

OK. But honestly, I really don't think you have to worry about it at all.

Thanks for the info!
