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.

I mean for most Linux derivatives, getting SSH setup for outgoing connections is usually install the
openssh
package from your distros repos, though I imagine many preinstall it, no reboot should be necessary, and you just typessh user@hostname
into a terminal to connect to the remote ssh server to access stuff on that computer. There shouldn't be a need to reboot for installing app that's not a service.Wanting to enable ssh access to the computer you are using so a remote client can connect to it? Well the same
openssh
package should have come withsshd
which acts as the server to allow remote ssh client to connect. It'd probably need enabling (so it's run automatically on boot) and starting (so you don't have to reboot to have it going), on distributions using systemd that's usually justsystemctl enable sshd.service
(which makes sure the sshd daemon will be started on next boot) followed bysystemctl start sshd.service
to start it immediately so it's running straight away, (orsystemctl enable sshd.service --now
to roll both steps into one).
