![]() Used for WoL magic packets are UDP 7 and 9. Sent out by professional software made for any platform, but can alsoīe sent by routers and internet-based websites. That includes the NIC’s MAC address in it. This related question seems to indicate that NAT traversal modifies the packet in some way, which prevents it from actually waking the PC. Let me show you how to use it to send a WoL magic packet. WoL-enabled computers essentially wait for a “magic packet” to arrive If I run wireshark on the machine and send the magic packet over WAN, it is indeed received by the PC. To send the magic packet in Windows, we will use WakeMeOnLan, a free and lightweight software. Some routers do not support this as they will not forward broadcast packets. ![]() Some routers permit the packet to be broadcast to the entire LAN. If the magic packet is coming from the internet (WAN) then any firewall must be set up to allow entry of the Wake-on-LAN signal to a specified port, which can be forwarded to the computer to be woken up If the PC is Wake-on-LAN enabled it will be listening for packets on the above ports. The MAC address is used to identify the particular host that should "Wake Up" The packets are sent to the special broadcast address of the LAN, so it will be received by all network-attached hosts, rather than by a specific host. Wake-on-LAN normally uses UDP ports 7 and 9. The old FOG server did not require this change so I may have to reverse it before going into production.Does Wake-on-LAN via WAN need port forwarding? WOL sends coded network packets, called magic packets, to systems equipped and enabled to respond to these packets. I replaced “255.255.255.255” with the network’s broadcast address and now it works fine. Wake On LAN (WOL) The WOL (Wake On LAN) feature allows the administrator to remotely power up all sleeping machines so that they can receive updates. Reviews on the Windows app store are generally good and positive and the tool has a. You just need to click the computer’s icon in the tool’s window and choose Send WOL (Magic Packet) There’s not much more that can be said about this tool. If( socket_sendto($soc, $strRaw, strlen FONT=monospace, 0, “255.255.255.255”, 9) ) Once devices are added to the tool, sending the Wake-on-LAN magic packet is a simple task. In the file /var/there is the following line: Does anyone have any insights?įigured it out. This did not happen with our old FOG server. So it seems the magic packet doesn’t reach the network when sent from the server. And the Apache error logs contain the following lines: PHP Warning: socket_sendto() unable to write to socket : Network is unreachable in /var/pn Line 36. I also tried creating the “testwol.php” file. I haven’t changed any settings related to Wake On LAN. The three WOL PHP files look identical to the ones Tom laid out here. However for some reason the FOG server won’t send out Magic Packets. I was able to successfully wake up the two client computers using a third party tool called WakeMeOnLan. ![]() My test network only consists of three Optiplex 780s (server included) and a Netgear Pro-Safe 8 port switch. The imaging itself works fine, but the computer must be manually powered on. Whether I start an imaging task or a Wake Up task, a computer that is off will stay that way. Basically it doesn’t work when initiated through FOG.
