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.

Restart your ssh server to be sure (probably sudo systemctl restart sshd). No need to reboot your server for this.

I don't know how reliable this is, but I usually go into htop to check if stuff needs to be restarted. Processes in red have been replaced or removed since starting.

That said, regular server reboots are a good idea to make sure kernel patches are applied. Can't go wrong with a reboot just in case.
