Remote shutdown a PC from visualization

[admin]

You can install Lua + Luasocket on Linux and create a simple script which receives UDP messages on a certain port. Then just do os.execute('poweroff') (or 'sudo poweroff' if not running a root) when a certain message is received.

Code:

sock = require('socket').udp()
sock:setsockname('*', 12345)
sock:settimeout(1)

while true do
  msg = sock:receive()
  if msg and msg == 'shutdown' then
    os.execute('poweroff')
  end
end

Then you can shutdown from LM like this:

Code:

sock = require('socket').udp()
sock:sendto('shutdown', '192.168.1.11', 12345)
