Shutting Down the Windows Computer Remotely from Linux

Prepare the remote computer for remote shutdown. Follow the steps in the first section of this article to prepare the Windows computer for remote shutdown.

Find the remote computer's IP address. You'll need to know the remote computer's IP address in order to shut it down from Linux. There are several ways you can determine this: Open the Command Prompt on the remote computer and type ipconfig. Look for the IPv4 address. Open your router's configuration page and look for the DHCP client table. This will display all of the devices connected to your network.

Open the Terminal on the Linux computer. The Linux computer will need to be connected to the same network as the Windows computer you are shutting down.

Install Samba. This protocol is required to connect to the Windows computer. The following command will install Samba in Ubuntu: sudo apt-get install samba-common You'll be required to enter your Linux root password in order to proceed with the installation.

Run the remote shutdown command. Once the Samba protocol has been installed, you can perform the shut down command: net rpc shutdown -I IP address -U user%password Replace IP address with the remote computer's IP address (e.g. 192.168.1.25) Replace user with the Windows user's username. Replace password with the Windows user's password.

Shutting Down a Mac Computer Remotely

Open the Terminal on another Mac on your network. You can use the Terminal to shut down any Mac on your network that you have administrator access to. You can find the Terminal in the Utilities folder in your Applications directory. You can do this from Windows by using an SSH program such as PuTTY to connect to the Mac via the command line. See Use SSH on Windows for details on using PuTTY. Once you're connected via SSH, you can use the same following commands.

Type .ssh username@ipaddress. Replace username with your username for the remote computer. Replace ipaddress with the remote computer's IP address. See Find Your IP Address on a Mac for details on finding a Mac's IP address.

Enter your user password for the remote Mac when prompted. After entering the command on the previous step, you'll be prompted to enter the password for that user account.

Type .sudo /sbin/shutdown now and press ⏎ Return. This will immediately shut down the Mac computer remotely, and your SSH connection with the computer will be severed. If you'd rather restart the computer, add -r after shutdown.
