In this tutorial, you’ll see how to install OpenSSH and configure it to enable SSH on Ubuntu and Debian based Linux distributions. Remember that SSH is only a protocol and this can protocol can be implemented via a number of tools such as lsh, Dropbear etc., but the most widely used tool for SSH is the open source software OpenSSH. Now the question is how do you enable SSH on Ubuntu or Debian or any other Linux distributions you are using? SSH, short for secure shell, is a protocol that allows remote login securely from one computer to another. So how do you remotely connect to a Linux system? There are multiple tools available for remote logins but when it comes to Linux, SSH is the most popular choice. In an IT environment, almost all the sysadmin tasks these days are performed via remote logins.Īnd not just sysadmins, even normal users sometimes need to remote login to the servers. Read the rest of the article for more detailed information.Įvery system admin and developer has experienced the need for remote logins into the systems for quicker administration and debugging purposes. If you want to enable SSH on Ubuntu server, use the following command: Remember to use the custom port when connecting to your system via SSH in the future.If you want to enable SSH on Ubuntu desktop, use the following command: For example, if your system's IP address is 10.20.30.40 and you've changed the SSH port to 33556, use the following command: ssh -p 33556 successfully enabled SSH, configured the necessary firewall rules, and changed the default SSH port on your Ubuntu 22.04 system. When connecting to your system via SSH, make sure to specify the new custom port. If the configuration was successful, you should see information about the SSH service running with the new port number. To verify that SSH has been enabled and the new SSH port and firewall rules have been configured correctly, run the following command in the terminal window: sudo systemctl status ssh Restart the SSH service to apply the changes: sudo systemctl restart ssh Step 7: Verify the Configuration Then, add a new rule for the custom SSH port: sudo ufw allow 33556/tcp Step 6: Restart the SSH Service First, delete the previous SSH rule: sudo ufw delete allow ssh

Update the firewall rules to allow inbound connections on the custom SSH port. Step 5: Configure Firewall Rules for the Custom SSH Port Remove the # at the beginning of the line to uncomment it. Next, open the SSH configuration file using a text editor like nano: sudo nano /etc/ssh/sshd_configįind the line that starts with #Port 22 and change it to the desired port number. You can choose a different port number if you prefer, but make sure it's not already in use by another service.įirst, create a backup of the original SSH configuration file: sudo cp /etc/ssh/sshd_config /etc/ssh/sshd_config.bak In this example, we'll change the default SSH port from 22 to 33556. Next, allow inbound SSH connections by adding a new firewall rule: sudo ufw allow ssh Step 4: Change the Default SSH Port If UFW is inactive, enable it with the following command: sudo ufw enable First, check the status of UFW by running: sudo ufw status Run the following command in the terminal window: sudo apt install openssh-server Step 3: Configure Firewall Rules for SSHīy default, Ubuntu comes with the Uncomplicated Firewall (UFW) to manage firewall rules. To enable SSH on your Ubuntu system, you'll need to install the OpenSSH server.
