![]() ![]() but gets no answer, because the target PC is powered off. So, per the standard procedure for forwarding unicast traffic, the router will first make an ARP request to find out the MAC address of the target PC. The forwarding rule in the router specifies the target PC's own IP address as the inner IP address. The magic packet is addressed to the router's external IP address, which makes it an unicast packet. The tricky part in sending Wake-on-LAN packets in from beyond the local network is in getting the router send the packet out to the local network, so that the completely passive PC1 can receive it. Python3 wakeonwan-paramiko.py can wakeup my home pc from external network,i feel it is more simple to edit wakeonwan.py to wakeup pc remotely? Ssh.connect(host, username=username, password=password,port=10000) Ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) pip install paramikoĮidt wakeonwan-paramiko.py: import paramiko It encounter no error,why pc1 can't wakeup with wakeonwan.py? Send_magic_packet(mac, ip_address=target_ip,port=9) Turn off pc1,wakeup it from pc2 with the following python code wakeonlan.py: from wakeonlan import send_magic_packetĮxecuting the command python3 wakeonlan.py in pc2 can wakeup my pc1 successfully.Įxecuting the command python3 wakeonwan.py remotely(for example-in my company's pc) can't wakeup my pc1. Issue wol command from the router: /usr/bin/wol -i 192.168.31.255 xx.xx.xx.xx Which interface to choose from the below options? Name protocl outer port inner IP address inner portĪnd bind the ip address and mac in openwrt: ip address mac interface The openwrt is running on my router,adding some port forwarding rules in the router and open firewall: forwarding rule Those last ones may require ARP offload to be enabled. It will cause the card to wake the machine when various things come in, including a magic packet, a NetBIOS name query, a TCP SYN packet (either TCPv4 or TCPv6), etc. Wake on Pattern Match is a superset of the previous one (Wake on Magic Packet). Usually, UDP is used, but sometimes raw frames with EtherType 0x0842 are used. That sequence can appear anywhere within the frame, so the packet can be sent over any higher-level protocol. A packet is considered "magic" when it contains FF FF FF FF FF FF (six instances of the largest possible byte value) followed by sixteen instances of the card's six-byte MAC address. Wake on Magic Packet causes the network card to awaken the computer when it receives a magic packet. ![]()
