Mobile phone magic wand: Remote Computer Shutdown

In this article, the mobile phone uses a computer to access the Internet and needs to be remotely shut down during sleep (too cold, too lazy to get up ^_^ ).

I mentioned how Android phones use computers to access the Internet (http://www.cnblogs.com/MikeZhang/archive/2012/02/04/androidComputerWifi.html ),
This articleArticleIt will be followed by an introduction to how to remotely shut down (taking windows as an example to provide an idea ).

Imagine this scenario: using an Android phone in the bed in winter, surfing the Internet through a computer (watching videos ......), Get up and shut down your computer while you are sleeping ...... It's not good!
So we need a remote shutdown software, but we can't trust it from a third party. What should we do?
Write it yourself!
In fact, it is very simple. The principle is as follows:
WINDOWS shutdown command: "shutdown-s-t 0 ",ProgramThe principle is to trigger this call through socket.
Here is a python example.Code, You can rewrite it.

PC server code:

 1   '''  
  2   File: shutdownsvr. py
  3  Author: Mike
  4   E-mail: Mike_Zhang@live.com
  5   ''' 
 6   Import Socket, OS
 7 Sock = socket. socket (socket. af_inet, socket. sock_stream)
 8 Sock. BIND (( '  192.168.123.1  ' , 12345 )) # My IP  
  9 Sock. Listen (5)
 10   While True:
 11 Connection, address = sock. Accept ()
 12       Try :
 13 Connection. setTimeout (5)
 14 Buf = connection. Recv (1024)
 15           If Buf = '  Shutdown  ' :
 16 OS. System ( '  Shutdown-s-t 0  ' )
 17       Except Socket. Timeout:
 18           Print   '  Time out  '   
19 Connection. Close ()
 20      

Android client code:

 1   '''  
  2   File: shutdowncli. py
  3   Author: Mike
  4   E-mail: Mike_Zhang@live.com
  5   ''' 
 6  Import Socket
 7 Sock = socket. socket (socket. af_inet, socket. sock_stream)
 8 Sock. Connect (( '  192.168.123.1  ' , 12345 ))
 9 Sock. Send ( '  Shutdown  ' )
 10 Sock. Close ()

Tip: Python needs to be installed on Android
Okay, that's all. I hope it will help you.
