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.

What don't you completely understand about Linux firewall? I don't mind helping you learn
Thank you everyone, also @[email protected] @[email protected].
For example, if I open my settings (I'm on Ubuntu+KDE) I don't see any firewall settings to configure. So I expect this is automatically done by the OS, but maybe I'm wrong. A bit surprised that the system itself doesn't recommend using a firewall, to be honest.
Many firewall tutorials start speaking about "your server". Then I wonder: is this really for me? I don't have a server. Or do I?
I now see that the tutorial from @[email protected] gives a better explanation, cheers! So I see it's good to have a firewall simply because one connects to public wifis from time to time.
I see that both UFW and firewalld are recommended... is it basically OK whichever I choose?
Yes. Whichever works for you should be fine. In the end you should be able to manage it
go with firewalld ufw floods dmesg with useless messages
