Turning off a computer that is on opposite ends of the room using CMD

post #1 of 35
Thread Starter 
Greetings all.
Is it possible to turn off a computer that is on the same network, but on opposite ends of the room using CMD?

I heard it is possible from my teacher, but he doesn't want to tell me how to do it. Mind helping me surprise him? biggrin.gif

open command prompt type in this
shutdown -s -m \\[INSERT COMPUTER NAME HERE] -t 60 -c "haha you have been hacked"


this will display quoted message for 60 seconds before shutting down


in case your teacher decides to counter hack you and shutdown your computer use command
shutdown -a

to abort his shutdown


note: this requires that you know the teachers computer name
if your on the same network, then use command
net view

to see all people on that network, it will show the computer names of everyone on, so then you can input that into the shutdown command previously stated

lookin at the guy who shut down an entire library, with 55 computers
hahahahhaha the librarians face was price less

whats more evil is installing the command in a start up folder so every time a computer turns on the whole library turns off

I would not have trusted myself with this knowledge, every computer I could find would be shutdown. My school had a pretty nice setup too, each room that had a significant number of computers were tied to a network, and nearby rooms that only had a few would also be connected. I then think each individual network went through a main network before going off compass to a cyber security firm which blocked websites deemed innappropriate. We figured out admins weren't blocked by as many sites, as most networks are, so we realised unplugging the Ethernet cord right as we hit login would remove most restrictions because our user account privilege couldn't fully load.

Well I knew right away teachers had more websites unlocked to them, but it took till senior year to figure out the Ethernet trick. I could find my way around computers for the most part, but when it came to networking and code I was lost. Most anything that was advanced or highly technical was beyond my abilities.

Edit: I'm officially voting this becomes a thread about funny stories with High School computer pranks and a how to. Nothing to malicious though, or could do permanent damage.

I don't quite get it... if I remove the ethernet cable right as I hit enter to a website, I could get through?

Pranks?
I installed the folding SMP clients...in about 40 computers or so in one room. The computers weren't crazy fast....they had a Pentium D clocked at 2.13GHz I think. I left them the entire day to fold until they were restarted. I didn't think I could get the entire room of 60 computers...and that is just 1 out of like 10 rooms. Oh boy, did the rooms heat up! biggrin.gif I made a good amount of points that day.

I just wrote a program to give me full permissions for whatever I wanted access too. This was at college though and on Win95 networks. At highschool the internet was on 1 standalone PC (which probably just had dial up) and all the rest of the computers were dumb terminals running Windows 3.0 (with one "posh" computer lab running Win3.11). We didn't even have a a typical RJ45 / cat5 network - it was all coax plugs it was that long ago.

Hacking those machines (both high school and college) was like shooting fish in a barrel.

</feels old>

I did right one trojan that I installed on every computer at college. This app would hide in the background and gave me complete control over the PC: I could shutdown programs or the entire machine, send keystrokes / mouse movements to is, launch apps, all sorts. It was great fun to tease people with. devil-smiley-019.gif

Testing it on the PC I have at home, this is what I come up with:
338

The PC doesn't have any firewall or anti virus in it. Is there a way to get around this?

EDIT: I get this when I use the square brackets:
