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.

    I recommend reading “TCP/IP Illustrated: Volume 1, Second Edition” if you want to learn more about networking. Make sure it’s the second edition, because the first edition is very old. The second edition is also over a decade old now, but it’s still almost completely correct, as the basics haven’t changed much. And don’t mistake the book to be overly simplified because of the title; it’s a very technical book that references the actual RFCs wherever appropriate.
