Remote Shutdown of a Linux / Unix Computer From MS-Windows

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.

    What is the point?
    And can explain me this again, please? Cause it doesn’t seam to work with my servers (not even laptop), cause I am using key based authentication and password authentication is off and won’t be turn on (it is insecure).
