last updated in Categories ,

How do I shutdown remote Linux or UNIX system from MS-Windows system?

You can use secure shell (ssh), a network protocol for remote administration of Linux and Unix based computers. SSH is typically used to log into a remote server and execute commands such as reboot or shutdown.


PuTTY SSH Client

PuTTY is a free and open source terminal emulator application which can act as a client for the SSH under MS-Windows operating system. Visit this page and download putty client. In order to use putty you need to know:

  • IP or Server Name: The name of the Linux or UNIX server you want to connect to.
  • Username and password: Login name or password to used on your server.

If you don’t know what login name or password to use, contact the administrator of your server.
