Enabling Ssh On Ubuntu

To enable SSH on Ubuntu, open the terminal and install the openssh-server package by running “sudo apt update” and “sudo apt install openssh-server. ” This allows for secure remote access to the system.

Enabling SSH on Ubuntu

Checking If Openssh Is Installed

To enable SSH on Ubuntu, firstly, you need to check whether OpenSSH is installed on your system. Open your terminal application and use the following command:

dpkg -l | grep openssh-server

If OpenSSH is installed on your system, you will see the package details in the output. Otherwise, you need to install it using the command:

sudo apt-get install openssh-server

Enabling Openssh Server

Once OpenSSH is installed, you can enable the OpenSSH server on your Ubuntu system. Run the following command:

sudo systemctl enable ssh

This command will start the OpenSSH server and ensure it runs automatically whenever your system starts up.

Changing The Default Port For Openssh Server

If you want to enhance the security of your SSH server, it is recommended to change the default port. To do this, follow the steps below:

  1. Open the SSH configuration file using the following command:
sudo nano /etc/ssh/sshd_config
  1. Locate the line that specifies the SSH port (usually port 22) and change it to your desired port number.
  2. Save the changes and exit the editor.

Restarting The Ssh Service

After changing the SSH port, you need to restart the SSH service to apply the changes. Run the following command:

sudo systemctl restart ssh

Testing The Ssh Connection

Finally, you can test the SSH connection to ensure everything is set up correctly. Open your terminal application and use the following command:

ssh username@your_server_ip -p your_port_number

Replace “username” with your actual username, “your_server_ip” with the IP address of your Ubuntu server, and “your_port_number” with the port number you set in the previous step.

Congratulations! You have successfully enabled SSH on your Ubuntu system. Now you can securely access your server remotely.
