How to Do a Remote Shutdown for a PC on a LAN

[Karlas]

So yeah,the title says it all,is there anyway to do it?
Thanks

If it is a Linux (or other UNIX-like) OS and you have ssh access and root access, you can give the remote PC the command "init 0". That is a zero.

On the remote machine (which you want to power off) install openssh-server:

apt-get install openssh-server

On your computer open up a terminal and:

ssh -l yourusername_on_the_remote_computer IP_OF_REMOTE_COMPUTER

eg:

ssh -l john 192.168.1.100

There will be a warning about adding the computer to the trusted ones.
Enter: yes

Then:

sudo halt

You can execute any command just like you sit in front of the remote computer...

Good luck!

On the computer you want to shut down, install openssh-server.

sudo apt-get install openssh-server

To shut down the computer remotely:

Open a terminal (ctrl+alt+t) and type:

ssh <username>@<machine ip address>

Replace <username> and <machine ip address> with the username and ip address of the machine you want to shut down. If you don't know the ip address, type "ifconfig" into the terminal (on the machine you want to turn off remotely)

Once your have logged in successfully with ssh, run:

init 0

Alternatively, you can run "sudo shutdown -h now" or "sudo halt".

Ok I got the idea,1 more question,I could just run downstairs and check my other computers IP,but is there anyway to see it without doing that?Im using wlan.

You can check it via your router's web interface.
You can also use the hostname of the machine or assign a fix address to the computer via the router's DHCP fixed leases table.

set a static ip address or use the computer's name
eg
ssh me@lucid-desktop.local
instead of
ssh me@10.0.0.50
my computer name is lucid-desktop you add the .local to it and you will have a name instead of a ip address to connect to

[Karlas]

Oh Is there a way to find out username and hostname of that computer?????

[Karlas]

ssh: Could not resolve hostname xxx: Name or service not known
