Forums/getfile/583194' alt='Vista Home Lan Manager Authentication Level' title='Vista Home Lan Manager Authentication Level' />L is an Ethernet or token ringcomputer networking standard that allows a computer to be turned on or awakened by a network message. The message is usually sent to the target computer by a program executed on a device connected to the same local area network, such as a smartphone. It is also possible to initiate the message from another network by using subnet directed broadcasts or a WOL gateway service. Equivalent terms include wake on WAN, remote wake up, power on by LAN, power up by LAN, resume by LAN, resume on LAN and wake up on LAN. If the computer being awakened is communicating via Wi Fi, a supplementary standard called Wake on Wireless LAN Wo. WLAN must be employed. The WOL and Wo. WLAN standards are often supplemented by vendors to provide protocol transparent on demand services, for example in the Apple Bonjour wake on demand Sleep Proxy feature. HistoryeditIn October 1. Intel and IBM formed the Advanced Manageability Alliance AMA. In April 1. 99. 7, this alliance introduced the Wake on LAN technology. Principle of operationeditEthernet connections, including home and work networks, wireless data networks and the Internet itself, are based on frames sent between computers. Wake on LAN 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. The magic packet contains the MAC address of the destination computer, an identifying number built into each network interface card NIC or other ethernet device in a computer, that enables it to be uniquely recognized and addressed on a network.

Powered down or turned off computers capable of Wake on LAN will contain network devices able to listen to incoming packets in low power mode while the system is powered down. If a magic packet is received that is directed to the devices MAC address, the NIC signals the computers power supply or motherboard to initiate system wake up, much in the same way as 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. It is a common misconception that because Wake on LAN is built upon broadcast technology it can only be used within the current network subnet. While this is generally the case, there are some exceptions, 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. This consumes a small amount of standby power, much less than normal operating power. The link speed is usually reduced to the lowest possible speed to not waste power e. Gigabit Ethernet NIC maintains only a 1.

Disabling wake on LAN when not needed, can very slightly reduce power consumption on computers that are switched off but still plugged into a power socket. Magic packeteditThe magic packet is a broadcast frame containing anywhere within its payload 6 bytes of all 2. FF FF FF FF FF FF in hexadecimal, followed by sixteen repetitions of the target computers 4. MAC address, for a total of 1. Since the magic packet is only scanned for the string above, and not actually parsed by a full protocol stack, it may be sent as any network and transport layer protocol, although it is typically sent as a UDPdatagram to port 0,6 7 or 9, or directly over Ethernet as Ether. Type 0x. 08. 42. 7A standard magic packet has the following basic limitations Requires destination computer MAC address also may require a Secure. On passwordDoes not provide a delivery confirmation. May not work outside of the local network. Requires hardware support of Wake On LAN on destination computer. Most 8. 02. 1. 1 wireless interfaces do not maintain a link in low power states and cannot receive a magic packet. The Wake on LAN implementation is designed to be very simple and to be quickly processed by the circuitry present on the network interface card with minimal power requirement. Because Wake on LAN operates below the IP protocol layer, IP addresses and DNS names are meaningless and so the MAC address is required. Subnet directed broadcastseditA principal limitation of standard broadcast wake on LAN is that broadcast packets are generally not routed. This prevents the technique being used in larger networks or over the Internet. Subnet directed broadcasts SDB89 may be used to overcome this limitation. SDB may require changes to intermediate router configuration. Subnet directed broadcasts are treated like unicast network packets until processed by the final local router. This router then broadcasts the packet using layer 2 broadcast. This technique allows a broadcast to be initiated on a remote network but requires all intervening routers to forward the SDB. When preparing a network to forward SDB packets, care must be taken to filter packets so that only desired e. Wo. L SDB packets are permitted otherwise the network may become a participant in DDo. S attacks such as the Smurf Attack. Troubleshooting magic packetseditWake 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. In some cases, hardware may wake from one low power state but not from others. This means that due to hardware issues the computer may be waking up from the fully off state S5 but doesnt wake from sleep or hibernation or vice versa. 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 computers NIC. The same magic packet can then be used to find out if the computer powers up from an offline state. This allows networking issues to be isolated from other hardware issues. 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 packets internals. In Windows Vista and higher, one can also determine how the OS was powered up. Running the powercfg. CMD prompt will list the Wake Source. The Wake on LAN event should also be logged in the System event log. Unauthorized accesseditMagic 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 Secure. On. It allows users to store within the NIC a hexadecimal password of 6 bytes. Clients have to append this password to the magic packet. The NIC wakes the system only if the MAC address and password are correct.
