From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Firewalls: what SHOULD I block? (lemmy.wtf)

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.

Who said anything about it being standard? I said I know this CAN happen, and I said it was quite some time ago. We can only hope this insanity isn't still in practice anywhere, but I learned long ago that expecting a corporation to NOT do foolish things will give me the same disappointing results as expecting money to come out of my ass. If there's a manager involved, then something on the tech side is going to get fucked up in the name of saving a buck. Therefore I cannot just assume OP gets a normal NAT address, nor can I assume they have any other firewall type device between them and the internet. With limited data, the best I can do is try and provide some general information, hopefully encourage them to ask more questions or provide more specific information, and just hope they don't have a ridiculously stupid ISP that makes things needlessly complicated.
