Python shutdown Description

Python boot

About to turn on the program, it is how to do it? This is WOL technology Wake-On-Lan, using a computer during shutdown or hibernation state, the main plate portion, and the card is still a weak power, of course, is to keep the power plug, and a wired connection. Therefore, even if the phone is turned off, the card still has some operational capability, you can monitor external computer online broadcast information, when the discovery of information in a specific format performs a power. Now the basic motherboards support.

Only you need to configure the following two options in the network adapter properties

The hook can not be selected on the following figure, we have to ensure that the card is still in power after the shutdown, if you shut down the network port does not light up, to die, to keep the Ethernet port lights.

This particular data also has a nice name Magic Packet (magic packet). UDP protocol generally used for broadcast. 9. The port is typically 7 or magic packet is always "FF FF FF FF FF FF" 6 consecutive "FF", followed by the MAC address information, once the card detect packet content, it will wake up the target computer.

We also look at how to write code, the code related to this UDP network programming, network programming later would write a special piece of content. This function can simply enter the MAC address of the target computer, LAN (Of course, if your computer has a public IP, it is also possible in the public network) to run the program on another computer, you can target computer automatically.

The following code, the code itself is very short, the principle is very simple:

def wake_up(mac='DC-4A-3E-78-3E-0A'):  
    MAC = mac  
    BROADCAST = "192.168.0.255"  
    if len(MAC) != 17:  
        raise ValueError("MAC address should be set as form 'XX-XX-XX-XX-XX-XX'")  
    mac_address = MAC.replace("-", '')  
    data = ''.join(['FFFFFFFFFFFF', mac_address * 20])  # 构造原始数据格式  
    send_data = b''  
  
    # 把原始数据转换为16进制字节数组，  
    for i in range(0, len(data), 2):  
        send_data = b''.join([send_data, struct.pack('B', int(data[i: i + 2], 16))])  
    print(send_data)  
  
    # 通过socket广播出去，为避免失败，间隔广播三次  
    try:  
        sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)  
        sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)  
        sock.sendto(send_data, (BROADCAST, 7))  
        time.sleep(1)  
        sock.sendto(send_data, (BROADCAST, 7))  
        time.sleep(1)  
        sock.sendto(send_data, (BROADCAST, 7))  
  
        print("Done")  
    except Exception as e:  
  
        print(e)

Python shutdown

Shutdown is relatively much easier online, there are many ready-made solutions. Most of the program is to scan the mailbox, if you receive a message related to the shutdown keyword, the program automatically performs a shutdown command. Also, if only implemented in LAN off, or you have a public IP address, you can also play a service on the local computer, such as running on port 5000 with Flask. It can send commands to the 5000 address. This program needs to have a command to execute shutdown

import os  
os.system('shutdown -s -t 00')

end

Finally say one more thing, a lot of people learn Python process will encounter a variety of problems to worry about, no one easy answer to give up. Xiao Bian is a python development engineer, here I am finishing up a new system python tutorials, ranging from basic web development python script to, reptiles, data analysis, data visualization, machine learning.
