Authentication-A first option for defense against packet sniffers is to use strong authentication, such as one-time passwords.The received WOL Packet contains MAC Address 00E04C3103AC and empty password.The following techniques and tools can be used to mitigate sniffers: The example below shows the packet sent from IP 192.168.1.4 to subnet-directed broadcast address 192.168.1.255 and destination port 7. Start your Wake-On-Lan tool which be used to send out magic packets. Start Wake-on-LAN Packet sniffer on the target (tested) machine.Last two ways requires configuration of the routers for each subnet. If the router or switch still has cached what port that computer is attached to, packet gets access to the machine. Unicast: the Packet sent directly to the machine IP address.The router or switch will forward the packet to all the machines on the subnet. Subnet-directed broadcast: the Packet sent to the target machine subnet.Limited broadcast: the Magic Packet sent to the limited broadcast address (255.255.255.255) it is received by all machines on the same subnet but not forwarded to machines on other subnets.There are three different ways to send Wake-on-LAN packets: This packet should contain a synchronization stream of 6 bytes of FFh and 16 times the repetition of the MAC address. The Magic Packet is a UDP broadcast message, that contains the Media Access Control (MAC) address of the network card of the target computer. Wake-on-LAN (WOL) technology is used for remote waking up machines from sleep state through special network packets (Magic Packet). Program will display all incoming 'Magic Packets'. It allows to check whether the target machine receive the packet or not. Wake-on-LAN Packet sniffer is designed to troubleshoot and setup Wake-on-LAN in the Network.
