Wake-On-LAN简称WOL,是一种电源管理功能;如果存在网络活动,则允许设备将操作系统从待机或休眠模式中唤醒。许多主板厂商支持IBM提出的网络唤醒标准。该标准允许网络管理员远程打开PC机电源,以便进行文件升级、资源跟踪和设备清点等工作。
先看下使用Python实现WakeOn Lan远程开机功能,具体介绍如下:
创建魔法唤醒包
格式化mac地址,生成魔法唤醒包,然后发送包,首先电脑需要打开wake on lan功能
创建main_wake_on_lan.py文件
import socketimport binasciiimport structimport re'''格式化mac地址,生成魔法唤醒包,然后发送。mac格式: mac = A1B2C3D4E5F6唤醒包格式: 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为这种形式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:将989096C1FECB格式的mac地址创建唤醒包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进制转换成整数 print(type(send_data)) return send_data# 方法二:将989096C1FECB格式的mac地址创建唤醒包,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)
调用发包函数
创建main_boot_computer.py
import main_wake_on_lanimport sysdef boot_computer(): try: pyname, parameter = sys.argv if parameter == '-h': print('参数使用方法: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, ' 发送魔法唤醒包!') # 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 + '发送唤醒包!' except ValueError: print('未收到传入的参数/n获取帮助:python3 main_boot_computer.py -h')if __name__ == '__main__': boot_computer()
