Introduction to using systemd to stop/start SSHD services

Overview

In this guide, we will learn how to use systemd to stop and start SSHD (Secure SHell Daemon) services on Linux systems. systemd is a system and service manager that provides a wide range of functions for managing various aspects of a Linux system.

Prerequisites

Before proceeding, you should have a basic understanding of Linux command-line operations and have access to a Linux system with systemd installed.

Stopping the SSHD service using systemd

To stop the SSHD service using systemd, follow these steps:

1. Open a terminal or SSH into your Linux system.
2. Log in as an administrator or a user with sudo privileges.
3. Type the following command to stop the SSHD service:

sudo systemctl stop sshd

The systemctl command is used to control systemd services, and the stop option is used to stop a specified service.

Starting the SSHD service using systemd

To start the SSHD service, follow these steps:

1. Open a terminal or SSH into your Linux system.
2. Log in as an administrator or a user with sudo privileges.
3. Type the following command to start the SSHD service:

sudo systemctl start sshd

The start option is used to start a specified service.

Checking the status of the SSHD service

You can also check the status of the SSHD service using systemd. To do this, follow these steps:

1. Open a terminal or SSH into your Linux system.
2. Log in as an administrator or a user with sudo privileges.
3. Type the following command to check the status of the SSHD service:

systemctl status sshd

This command will provide you with information about the current status of the SSHD service, including whether it is running or not.

Conclusion

In this guide, we have learned how to use systemd to stop, start, and check the status of the SSHD service on Linux systems. systemd provides a powerful and flexible way to manage services, making it easier for programmers and system administrators to control and monitor various aspects of their Linux systems.
