How To Restart SSH Service under Linux / UNIX

To restart the SSH (Secure Shell) service on a Linux or Unix system, you can use the service command with the ssh service name.

For example, to restart the SSH service, you can use the following command:

sudo service ssh restart

This will stop the SSH service, and then start it again.

If you want to stop the SSH service temporarily, you can use the stop option instead of the restart option. For example:

sudo service ssh stop

This will stop the SSH service, but it will not start it again. To start the service again, you can use the start option:

sudo service ssh start

It's important to note that restarting the SSH service will terminate all existing connections, so be sure to save any unsaved work before restarting the service.

Alternatively, you can use the systemctl command to restart the SSH service. For example:

sudo systemctl restart ssh

This will stop the SSH service, and then start it again. You can use the stop and start options with the systemctl command as well.

For example:

sudo systemctl stop ssh
sudo systemctl start ssh

It's a good idea to restart the SSH service if you have made changes to the SSH configuration and want them to take effect, or if you are experiencing connectivity issues that you suspect may be related to the SSH service. Restarting the service can help to resolve these issues and ensure that the service is running smoothly.
