Hey there folks,

I’m trying to figure out how to configure my UFW, and I’m just not sure where to start. What can I do to see the intetnet traffic from individual apps so I can know what I might want to block? This is just my personal computer and I’m a total newbie to configuring firewalls so I’m just not sure how to go about it. Most online guides seem to assume one already knows what they want to block but I don’t even know how/where to monitor local traffic to figure out what I can/should consider blocking.

    You don’t understand local host. Services listen on 127.0.0.1 which is a local only address. You can only connect to it locally

      who speaks about localhost? out of 21 active ports on my machine, only 3 is only listening on localhost. dhclient, avahi-daemon, syncthing, kdeconnect… cups-browsed did not listen only on localhost either
