Using the free PuTTY remote access client, you get an opportunity to connect different remote access protocols, to which rlogin, SSH, and Telnet can be referred. This also allows the client to work through the communications port.
Using PuTTY client, you can connect and get control of the server, or other remote host. With PuTTY client, the connection is made only on the client side, the work itself is done on the other side of the remote host.
Initially the client was created for the Microsoft Windows operating systems, but, nevertheless, it was also later ported to Unix OS. The ports for Mac OS are currently being developed. Also, third-party developers released unofficial ports for such mobile platforms as Windows Mobile, Symbian OS and others. This client is in production with the MIT license.
