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.

We haven't rewritten the firewall code lately, right? checks Oh, it looks like we have. Now it's nftables.
I learned ipfirewall, then ipchains, then iptables came along, and I was like, oh hell no, not again. At that point I found software to set up the firewall for me.
Damn, you're old. iptables came out in 1998. That's what I learned in (and I still don't fully understand it).
UFW → nftables/iptables. Never worry about chains again
I was just thinking that iptables lasted a good 20 years. Over twice that of ipchains. Was it good enough or did it just have too much inertia?
Nf is probably a welcome improvement in any case.
