Put the IP Address in the 'Internet Address' box, the Subnet Mask in the 'Subnet Mask' box, and the Ethernet ID in the 'Mac Address' box (remove the colons). Download the 'Wake On Lan' utility. Put your Mac to sleep, and take your noted numbers to your PC box. In System Preferences, go to 'Energy Saver,' click on the 'Options' tab, and make sure 'Wake for Ethernet network administrator access' is selected.

WoL is implemented using a specially designed frame called a magic packet, which is sent to all computers in a network, among them the computer to be awakened. Principle of operation Ethernet connections, including home and work networks, wireless data networks and the Internet itself, are based on frames sent between computers. A Gigabit Ethernet NIC maintains only a 10 Mbit/s link). The link speed is usually reduced to the lowest possible speed to not waste power (e.g. This consumes a small amount of standby power, much less than normal operating power. There are some exceptions, though, and Wake-on-LAN can operate across any network in practice, given appropriate configuration and hardware, including remote wake-up across the Internet.In order for Wake-on-LAN to work, parts of the network interface need to stay on. If a magic packet is received that is directed to the device's MAC address, the NIC signals the computer's power supply or motherboard to initiate system wake-up, in the same way that pressing the power button would do.The magic packet is sent on the data link layer (layer 2 in the OSI model) and when sent, is broadcast to all attached devices on a given network, using the network broadcast address the IP-address (layer 3 in the OSI model) is not used.Because Wake-on-LAN is built upon broadcast technology, it can generally only be used within the current network subnet. Does not provide a delivery confirmation Requires destination computer MAC address (also may require a SecureOn password) A connection-oriented transport-layer protocol like TCP is less suited for this task as it requires establishing an active connection before sending user data.A standard magic packet has the following basic limitations: The power drain becomes a consideration on battery powered devices such as laptops as this can deplete the battery even when the device is completely shut down.The magic packet is a frame that is most often sent as a broadcast and that contains anywhere within its payload 6 bytes of all 255 (FF FF FF FF FF FF in hexadecimal), followed by sixteen repetitions of the target computer's 48-bit MAC address, for a total of 102 bytes.Since the magic packet is only scanned for the string above, and not actually parsed by a full protocol stack, it could be sent as payload of any network- and transport-layer protocol, although it is typically sent as a UDP datagram to port 0 (reserved port number), 7 ( Echo Protocol) or 9 ( Discard Protocol), or directly over Ethernet as EtherType 0x0842. ![]() This router then broadcasts the packet using layer 2 broadcast. Subnet directed broadcasts are treated like unicast network packets until processed by the final (local) router. SDB may require changes to intermediate router configuration. Also, it is not always clear what kind of magic packet a NIC expects to see.In that case, software tools like a packet analyzer can help with Wake-on-LAN troubleshooting as they allow confirming (while the PC is still on) that the magic packet is indeed visible to a particular computer's NIC. This means that due to hardware issues the computer may be waking up from the "fully off state" (S5) but doesn't wake from sleep or hibernation or vice versa. In some cases, hardware may wake from one low power state but not from others. WoL) SDB packets are permitted – otherwise the network may become a participant in DDoS attacks such as the Smurf attack.Wake-on-LAN can be a difficult technology to implement, because it requires appropriate BIOS, network card and, sometimes, operating system and router support to function reliably. When preparing a network to forward SDB packets, care must be taken to filter packets so that only desired (e.g. Prolific clone usb cable driver installation for a macSecurity considerations Unauthorized access Magic packets are sent via the data link or OSI-2 layer, which can be used or abused by anyone on the same LAN, unless the L2 LAN equipment is capable of (and configured for) filtering such traffic to match site-wide security requirements.Firewalls may be used to prevent clients among the public WAN from accessing the broadcast addresses of inside LAN segments, or routers may be configured to ignore subnet-directed broadcasts (see above).Certain NICs support a security feature called "SecureOn". The Event Viewer and the powercfg.exe /lastwake command can retrieve them. In some cases they also confirm that the packet was destined for a specific PC or sent to a broadcast address and they can additionally show the packet's internals.Starting with Windows Vista, the operating system logs all wake sources in the "System" event log. This allows networking issues to be isolated from other hardware issues. However any network eavesdropping will expose the cleartext password. This security measure significantly decreases the risk of successful brute force attacks, by increasing the search space by 48 bits (6 bytes), up to 2 96 combinations if the MAC address is entirely unknown. The NIC wakes the system only if the MAC address and password are correct. Clients have to append this password to the magic packet. For example, Intel AMT (a component of Intel vPro technology), includes Transport Layer Security (TLS), an industry-standard protocol that strengthens encryption. Configuration of these two features in tandem often requires tuning of timing parameters and thorough testing.Some PCs include technology built into the chipset to improve security for Wake-on-LAN. Therefore, a combination of DHCP and PXE servers on the network can sometimes be used to start a computer with an attacker's boot image, bypassing any security of the installed operating system and granting access to unprotected, local disks over the network.Interactions with network access control The use of Wake-on-LAN technology on enterprise networks can sometimes conflict with network access control solutions such as 802.1X or MAC-based authentication, which may prevent magic packet delivery if a machine's WoL hardware has not been designed to maintain a live authentication session while in a sleep state. However, many client computers attempt booting from a PXE server when powered up by WoL. Abuse of the Wake-on-LAN feature only allows computers to be switched on it does not in itself bypass password and other forms of security, and is unable to power off the machine once on. ![]()
