Linux 遠端啟動計算機

1、檢視主控機是否支援

#ethtool eth0 settings for eth0: supported ports: [ tp mii ] supported link modes: 10baset/half 10baset/full 100baset/half 100baset/full 1000baset/full supported pause frame use: symmetric receive-only supports auto-negotiation: yes supported fec modes: not reported advertised link modes: 10baset/half 10baset/full 100baset/half 100baset/full 1000baset/full advertised pause frame use: symmetric advertised auto-negotiation: yes advertised fec modes: not reported link partner advertised link modes: 10baset/half 10baset/full 100baset/half 100baset/full 1000baset/full link partner advertised pause frame use: symmetric link partner advertised auto-negotiation: yes link partner advertised fec modes: not reported speed: 1000mb/s duplex: full port: mii phyad: 1 transceiver: internal auto-negotiation: on supports wake-on: pumbag wake-on: d current message level: 0x00000007 (7) drv probe link

link detected: yes

2、看到wake-on: d，表示沒有開啟wake控制，需要開啟為wake-on:g

#ethtool -s eth0 wol g #ethtool eth0 settings for eth0: supported ports: [ tp mii ] supported link modes: 10baset/half 10baset/full 100baset/half 100baset/full 1000baset/full supported pause frame use: symmetric receive-only supports auto-negotiation: yes supported fec modes: not reported advertised link modes: 10baset/half 10baset/full 100baset/half 100baset/full 1000baset/full advertised pause frame use: symmetric advertised auto-negotiation: yes advertised fec modes: not reported link partner advertised link modes: 10baset/half 10baset/full 100baset/half 100baset/full 1000baset/full link partner advertised pause frame use: symmetric link partner advertised auto-negotiation: yes link partner advertised fec modes: not reported speed: 1000mb/s duplex: full port: mii phyad: 1 transceiver: internal auto-negotiation: on supports wake-on: pumbag wake-on: g current message level: 0x00000007 (7) drv probe link

link detected: yes

這樣就開啟wake控制了。

3、python 程式設計

#!/usr/bin/python
# -*- coding: utf-8 -*-
import socket
import binascii
import struct
import re
'''格式化mac位址，生成魔法喚醒包，然後傳送。
mac格式： mac = a1b2c3d4e5f6
喚醒包格式： send_data = binascii.unhexlify('ff'*6 + str(mac)*16)
'''mac = "94:c6:91:72:d8:00"
# mac = "98-90-96-c1-fe-cb"
# 格式化mac位址989096c1fecb為這種形式
def format_mac0(mac):
if len(mac) == 12:
pass
elif len(mac) == 17:
if mac.count(':') == 5 or mac.count('-') == 5:
sep = mac[2]
mac = mac.replace(sep, '')
else:
raise valueerror('incorrect mac format')
else:
raise valueerror('incorrect mac format')
return mac
def format_mac(mac):
mac_re = re.compile(r'''
(^([0-9a-f][-])([0-9a-f])$
|^([0-9a-f][:])([0-9a-f])$
|^([0-9a-f][.])([0-9a-f])$
)''', re.verbose | re.ignorecase)
# print(re.match(mac_re, mac))
if re.match(mac_re, mac):
if mac.count(':') == 5 or mac.count('-') == 5 or mac.count('.'):
sep = mac[2]
mac_fm = mac.replace(sep, '')
return mac_fm
else:
raise valueerror('incorrect mac format')
def create_magic_packet0(mac):
data = b'ff' * 6 + (mac * 16).encode()
print(data)
print(type(data))
send_data = b''
for i in range(0, len(data), 2):
send_data = send_data + struct.pack(b'b', int(data[i: i + 2], 16))  # int(data[i: i+2], 16) 把16進製制轉換成整數
print(type(send_data))
return send_data
def create_magic_packet(mac):
data = 'ff' * 6 + str(mac) * 16
# print(data)
# print(type(data))
send_data = binascii.unhexlify(data)
# print(type(send_data))
return send_data
def send_magic_packet(send_data):
# broadcast_address = '192.168.255.255'
broadcast_address = '255.255.255.255'
port = 9
s = socket.socket(socket.af_inet, socket.sock_dgram)
s.setsockopt(socket.sol_socket, socket.so_broadcast, 1)
s.sendto(send_data, (broadcast_address, port))
if __name__ == '__main__':
mac = format_mac(mac)
send_data = create_magic_packet(mac)
# print(send_data)
send_magic_packet(send_data)

執行python wake_on_lan.py

開機成功。
