Every second, Pidgin attempts a multicast to 224.0.0.251 (UDP) port 5353. There is nothing about this on the web that I could find.
I not running Pidgin with the --force-online option.
Maybe I will try running with the --debug option.
I block that address because I don't trust all devices on my LAN. I would rather disable this multicast in Pidgin. And not stop getting the messages from the firewall when app does something weird like this.
Anyone know how to fix this broadcasting problem?
