How to Provide SSH: A Step-by-Step Guide

In the world of secure data transfer and remote server access, SSH (Secure Shell) stands out as a reliable and widely-used protocol. Whether you're a seasoned IT professional or a novice navigating the digital landscape, understanding how to provide SSH is a crucial skill. This step-by-step guide will walk you through the process, ensuring you can establish secure connections with ease.

  1. Understanding SSH:
    Before diving into the steps, it's essential to grasp the fundamentals of SSH. SSH is a cryptographic network protocol that enables secure data communication over an unsecured network. It's commonly used for remote access to servers and secure file transfers.

  2. Prerequisites:
    Before you can start providing SSH, ensure that you have the necessary credentials and permissions. You'll need the IP address or domain name of the server, along with the username and password or private key for authentication.

  3. Opening a Terminal or Command Prompt:
    The first step is to open a terminal on Linux or macOS or a command prompt on Windows. This is where you'll enter the commands to establish an SSH connection.

  4. SSH Command Syntax:
    The basic syntax for the SSH command is as follows:

    ssh [username]@[hostname or IP address]
  5. Using a Specific Port:
    If your SSH server operates on a port other than the default (port 22), you can specify it in the command:

    ssh -p [port] [username]@[hostname or IP address]
  6. Password Authentication:
    If you're using password authentication, the system will prompt you to enter the password for the specified username.

  7. Key-Based Authentication:
    For enhanced security, consider using key-based authentication. Generate a key pair, add the public key to the server, and provide the private key during authentication.

  8. Executing Commands Remotely:
    Once connected, you can execute commands on the remote server. Simply type the desired command after the SSH connection is established.

  9. Ending the SSH Session:
    To end the SSH session, type:


Step-by-Step Instructions:

  1. Open the terminal or command prompt on your local machine.

  2. Enter the SSH command with the appropriate syntax:

    ssh [username]@[hostname or IP address]
  3. If using a non-default port, include the port number:

    ssh -p [port] [username]@[hostname or IP address]
  4. Provide the password when prompted for password authentication.

  5. For key-based authentication, ensure your public key is added to the server, and provide the private key during authentication.

  6. Once connected, execute remote commands as needed.

  7. To end the SSH session, type:


More Examples:

  • Example 1:

    ssh john@
  • Example 2 (using a specific port):

    ssh -p 2222
  • Example 3 (key-based authentication):

    ssh -i ~/.ssh/private_key john@
