How do I restart sshd daemon on Linux or Unix?

To restart the "sshd" daemon (SSH daemon) on a Linux or Unix system, you can use the "service" or "systemctl" command. The "sshd" daemon is the daemon that provides the Secure Shell (SSH) service on a Linux or Unix system, and it must be running to allow remote access to the system via SSH.

To restart the "sshd" daemon on a Linux or Unix system, follow these steps:

1. Open a terminal and log in as the "root" user or a user with root privileges.

2. Type the following command to restart the "sshd" daemon using the "service" command:

service sshd restart

Or type the following command to restart the "sshd" daemon using the "systemctl" command:

systemctl restart sshd

3. The "sshd" daemon will be restarted, and any active SSH sessions will be terminated.

With these steps, you should be able to restart the "sshd" daemon on a Linux or Unix system using the "service" or "systemctl" command. Consult the documentation of "service" and "systemctl" for more information on how to use these utilities.

Note: The steps and commands may vary depending on the Linux or Unix distribution you are using. Consult the documentation of your distribution for more information on how to restart the "sshd" daemon.
