Wake-On-LAN簡稱WOL，是一種電源管理功能；如果存在網絡活動，則允許設備將操作系統從待機或休眠模式中喚醒。許多主板廠商支持IBM提出的網絡喚醒標準。該標準允許網絡管理員遠程打開PC機電源，以便進行文件升級、資源跟蹤和設備清點等工作。

先看下使用Python實現WakeOn Lan遠程開機功能，具體介紹如下：

創建魔法喚醒包

格式化mac地址，生成魔法喚醒包，然后發送包，首先電腦需要打開wake on lan功能

創建main_wake_on_lan.py文件

import socketimport binasciiimport structimport re'''格式化mac地址，生成魔法喚醒包，然后發送。mac格式： mac = A1B2C3D4E5F6喚醒包格式： send_data = binascii.unhexlify('FF'*6 + str(mac)*16)'''MAC = "18:31:BF:B0:36:8F"# MAC = "98-90-96-C1-FE-CB"# 格式化MAC地址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 macdef format_mac(mac): mac_re = re.compile(r'''      (^([0-9A-F]{1,2}[-]){5}([0-9A-F]{1,2})$      |^([0-9A-F]{1,2}[:]){5}([0-9A-F]{1,2})$      |^([0-9A-F]{1,2}[.]){5}([0-9A-F]{1,2})$      )''', 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')# 方法一：將989096C1FECB格式的mac地址創建喚醒包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進制轉換成整數 print(type(send_data)) return send_data# 方法二：將989096C1FECB格式的mac地址創建喚醒包，使用binascii.unhexlify()方法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_datadef 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__': # print('mac地址：', format_mac(MAC)) mac = format_mac(MAC) send_data = create_magic_packet(mac) # print(send_data) send_magic_packet(send_data)

調用發包函數

創建main_boot_computer.py

import main_wake_on_lanimport sysdef boot_computer(): try:  pyname, parameter = sys.argv  if parameter == '-h':   print('參數使用方法：python3 main_boot_computer.py mac地址/npython3 main_boot_computer.py 98:90:96:C1:FE:CB')  else:   print('正在向 ', parameter, ' 發送魔法喚醒包！')   # mac = '98:90:96:C1:FE:CB'   mac = main_wake_on_lan.format_mac(parameter)   send_data = main_wake_on_lan.create_magic_packet(mac)   main_wake_on_lan.send_magic_packet(send_data)   return '成功向' + parameter + '發送喚醒包！' except ValueError:  print('未收到傳入的參數/n獲取幫助：python3 main_boot_computer.py -h')if __name__ == '__main__': boot_computer()
