PuTTY is a widely used SSH client for windows; however, it supports various network protocols such as Telnet, rlogin. The system administrators use PuTTY as SSH and Telnet client as well. Telnet is a protocol used to establish communication between two or more devices in a network, but it was declared as an insecure protocol, so the ground for another protocol was clear. A new protocol named SSH (Secure Shell) was introduced that allows multiple devices to communicate over a network in a secure manner. PuTTY SSH client provides extensive support for well-known operating systems. In this article, we will guide you to install PuTTY as an SSH client on your Ubuntu, and before this basic working flow of the PuTTY is also described here:
