In an effort to analyse traffic more often, and just learn more, I'd like to reduce the amount of unnecessary traffic on my network - so it reduces the "noise" when I'm examining something.
On an Arch system with multiple interfaces it's sending out frequent requests to UDP port 1900, to IP 239.255.255.250, on all interfaces.
This is SSDP / UPnP related, and I've avahi installed but I'm not running avahi-daemon. So this is related to something like Samba or gvfs-smb or smbnetfs or similar, but how I do figure out which? I don't see a way to track this using fuser or lsof... what option am I missing?
Thank you.
