How To Restart Sshd Linux
This is an easy one, but anyway if someone, sometime need it, I'll write here how to restart the ssh service or the sshd daemon
Stop the sshd daemon. Restart: Equivalent to a stop and then a start command sequence. Reload: Force the sshd daemon to re-read its configuration files without a service interruption. Condrestart: If the sshd daemon is currently running, this is the same as a restart command. The process that is handling your current ssh session does not die when the main daemon is restarted. That's all the magic there is. Sshd listens on port 22 for incoming connections. When someone connects it spawns a new process for that connection and goes back to listening. See below we have sshd on process 14688 started by systemd (process 1). Finereader mac serial.
First, sshd is:
Secure Shell or SSH is a network protocol that allows data to be exchanged using a secure channel between two networked devices.[1] The two major versions of the protocol are referred to as SSH1 or SSH-1 and SSH2 or SSH-2. Used primarily on Linux and Unix based systems to access shell accounts, SSH was designed as a replacement for Telnet and other insecure remote shells, which send information, notably passwords, in plaintext, rendering them susceptible to packet analysis.[2] The encryption used by SSH is intended to provide confidentiality and integrity of data over an unsecured network, such as the Internet.

Note: Consider that if you do it remotely, you will not be signed out, unless of course there is something wrong with the configuration and the sshd daemon would not start again, so be careful
