Use of PuTTY

n a multi-user operating system like Unix, the interface is generally of command-line type, just like the command prompt or MS-DOS. As such the user needs to type in the command in the command line program to get anything processed by the system.


Generally, these commands can quickly be run over a network from a different computer on a different location (client) and the response is transferred over the network to the client.


The arrangement mentioned above is made possible with the help of network protocols like SSH, Telnet, Rlogin, etc. Interestingly, users can give commands to multiple computers simultaneously.


SSH (Secure Shell) protocol is a cryptographic network protocol that allows you to access an internet server while encrypting any information sent to that server.


Some of the other protocols include Telnet, Rlogin only if either you are connected to a Unix system or you have a login account on a web server (a shell account). PuTTY is one such application that enables this kind of transfer.

PuTTY supports the following protocols

  • SCP (Secure Copy)
  • SSH (Secure Shell)
  • Telnet
  • Rlogin
  • Raw socket connection.
