SSH (Secure Shell) is a network protocol that allows you to securely connect to a remote server or machine over an unsecured network.
It provides a secure way to access and manage remote systems. In this article, we will explore how to use SSH to connect to a remote server.
Before we begin, make sure you have the following:
- A remote server with SSH enabled.
- A local machine with SSH client software installed. (Most Linux distributions come with an SSH client pre-installed. If you're on Windows, you can use tools like PuTTY or Windows Subsystem for Linux (WSL) to access an SSH client.)
To connect to a remote server using SSH, follow the steps below:
- Open your terminal or command prompt on your local machine.
- Use the following command to connect to the remote server:
usernamewith your actual username on the remote server, and
remote_server_ipwith the IP address or domain name of the remote server.
- If this is your first time connecting to the remote server, you may see a message similar to the following:
The authenticity of host 'remote_server_ip' can't be established. RSA key fingerprint is 01:23:45:67:89:ab:cd:ef:01:23:45:67:89:ab:cd:ef. Are you sure you want to continue connecting (yes/no)?
Verify that the fingerprint matches the one provided by the server administrator, and type
- Next, you will be prompted for your password. Enter your password for the remote server and press Enter. Note that when you type your password, no characters will be displayed on the screen for security reasons.
Alternatively, you can use key-based authentication for added security.
If you have set up SSH key pairs, you can use the following command instead:
ssh -i path/to/private_key username@remote_server_ip
path/to/private_keywith the actual path to your private key file.
- Once you have provided the correct credentials, you will be connected to the remote server via SSH. You will see a command prompt indicating that you are now logged into the remote server.
SSH is a powerful tool for securely connecting to remote servers and managing them. In this article, we learned how to use SSH to connect to a remote server from your local machine. By following the steps outlined above, you can establish a secure connection and start working with your remote server.
Remember to replace
remote_server_ipwith your actual credentials and server information.
