Introducing Putty and its Features
What is Putty?
Putty is software used to communicate with a remote computer using the Telnet, Rlogin, and SSH protocols. We assume you have purchased your server and are now ready to configure it. You must use this software to connect and log in to the server.
Putty software is client-side software. This means that there must be a server at the network level for the software to be able to connect to it. Our server is the same SSH service that is currently running on our server. If the server is down or the SSH service is not running properly, you will not be able to connect to the server via the SSH protocol.
Putty was first developed in 1998 and, as mentioned, was originally designed for Windows. Later in 2000, the program became an SSH-2 client protocol. Then, software interfaces were provided to connect this emulator with other operating systems such as Linux, Windows Mobile, Mac OS, Mac Phone, etc.
It should note that Putty is a multi-platform application that can run on most operating systems. This program can configure for any type of server and features such as port transfer and public keys are providing in this program.
