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.

The SSH port is 22. This is the story of how it got that port number. And practical configuration instructions.

As freeware or free software? Because if it was freeware, I don't understand how OpenBSD could have forked it

It was a custom license more permissive than the BSD license.

It's still part of the official OpenSSH license, see the first section here: https://cvsweb.openbsd.org/src/usr.bin/ssh/LICENCE?rev=HEAD
