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.

    Wireshark

    what I might want to block?

    One strategy is to block everything, and open ports as needed. Beware that most guides focus on inbound traffic, whereas you seem to be focusing on outbound traffic.

      wireshark does not work for individual apps, it cannot make a difference between traffic of process a and b.

        I’m not sure how Wireshark is related to firewalls honestly. It is mostly a layer 1 and 2 tool

      Why are we recommending Wireshark? That doesn’t make any sense what so ever. If anything have them run a port scan with nmap.

      This is crazy advise
