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.
Well, screwed I will be, then. I’m not going to waste my life babysitting a bespoke firewall on my Ubuntu Desktop.
And it seems like a bad idea to be telling beginners on Ubuntu or Mint whatever that their “security philosophy is flawed” and they must imperatively run these 10 lines of mysterious code or else bad things will happen.
This whole discussion looks like a misunderstanding. OP is not a sysadmin on public-facing server. They are a beginner on a laptop at home.
