How to Establish an SSH Connection with Putty

SSH (Secure Shell) is a protocol used for secure data communication, remote command-line sessions, and other network services. Establishing an SSH connection using Putty is very simple. Here’s how you can do it step by step:

1. Download and Install Putty: First, download and install the latest version of Putty from the official website.
2. Launch the Program: After installation, open Putty, and you will be directed to the main screen.
3. Configure Connection Settings: Enter the information of the server you want to connect to in the Host Name (or IP address) field. The port number is usually set to 22.
4. Start the Connection: Select the SSH option, and then click the 'Open' button.
5. Authentication: Once connected to the server, enter your username and password to authenticate.

After following these steps, you will have established an SSH connection via Putty and can securely communicate with your remote server.

Using Telnet: Advantages and Disadvantages of Putty

Telnet is an older network protocol used for communication with other devices over the internet and LAN. Telnet is generally considered insecure as it does not provide any encryption during data transfer. However, it is still used in some cases.

The advantages and disadvantages of using Telnet with Putty are as follows:
