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.

Do you consider it to not be a helpful measure to take at all?
I have fail2ban configured - since it is reading from the auth.log, I guess I would not have to make any changes to the configuration there to have it work with a new port?
It's a mixed bag. Personally I wouldn't use a non-standard port.
Consider that port numbers under 1024 are Privileged Ports. You would either have to make sure that no other privileged service is running on the port you want to use for SSH when using another privileged port or you need to make sure that no unprivileged program tries to use the same port as your SSH service when using a non-privileged. Overall it adds a bit of overhead and possible headaches for barely any gain.
Fail2ban should work with a different port without any further configuration but it might not.
Alright, cheers - I'll leave it be as well then :)
