Wake on LAN is a computer networking standard which is also known as remote wake up, Wake up LAN, wake on wireless LAN, and resume on LAN, provides remote booting of network devices. Wake on LAN tool is widely used by network admins to provide uninterrupted IT resource availability. Since remote Wake on LAN standards are met by most device manufactures, Wake on LAN is now a commonly adapted network standard. In the following is discussed the implementation, working, functions, and advantages of Wake on LAN by using OpUtils Wake on LAN Software.
Several factors impede the implementation of Wake-on-LAN technology using WOL tools, such as the use of an appropriate BIOS or network card, the internal architecture of the target machine, and sometimes the reliability of the OS and router functionality hinders the full-fledged functionality of the Wake on LAN tool.
Hardware issues: By default, machines are expected to wake up from a low powered state, i.e., machines that are powered off but are still connected to a power source. Hardware issues, such as situations like those mentioned above, might wake up computers from sleep instead of from a fully off state, or vice versa when a Wake on LAN message is transmitted to it from the Wake on LAN Software.
Security threats: Wake on LAN Magic packets, which are sent via the data link layer by the Wake on LAN tool, can be used or manipulated by any attacker or rogue device in the same network. If the target computer boots from a Preboot Execution Environment (PXE) server, it could allow the computer to boot from an attacker’s boot image, bypassing any security and providing unauthorized access to local disks over the network.
To avoid these network mishaps, an effective software tool like OpUtils Wake-on-LAN should be used.
OpUtils' Wake-on-LAN tool enables admins to wake up machines remotely on demand. The Wake on LAN tool can be used to Wake up on LAN either a single machine or multiple machines simultaneously. Admins have the option to send the WoL packets to a specific system, or broadcast the WoL packets to whole subnets using the WOL tool. The status and the last wake-up time are automatically updated in the database.
OpUtils' Wake-on-LAN solution eases the use of WoL technology in a network by supporting both manual and scheduled wake-up. Equipped with real-time network scanning tools, Wake on LAN utility discovers and displays the MAC addresses in your network to help admins wake up a specific target machine. Also, OpUtils’ tree-based hierarchy of subnets helps admins efficiently broadcast WoL messages to the subnets in which the target machine(s) are present, using the OpUtils Wake on LAN tool.
With the Wake-on-LAN software, admins can add all the systems via scheduled wake-up to run at a specified interval: daily, monthly, or yearly. At the specified time, the tool sends the WoL packets to the systems to boot them up. The Wake on LAN monitor of the receiving device senses that the its Wake on LAN MAC is in the Wake on LAN magic packet broadcasted, the device boots up.
The Wake-on-LAN tool enables admins to create multiple groups containing different computers, and these groups can be scheduled to run at different times. There is no restriction on the number of groups that can be created. The status of individual tasks will be provided as a summary under Groups in Networking Tools by the Wake on LAN tool. The statuses of individual computers will also be available in the Status column under Devices in networking Tools.
For the Windows Wake-on-LAN tool and Linux Wake-on-LAN to work, the machines should meet the following requirements suggested for supporting Wake on LAN tools:
Wake-on-LAN (WoL) is a tool that remotely wakes up, or boots up, a wake on LAN devices present in the network that is powered off. Using a specially designed frame called a magic packet, which contains the target computer's MAC address, Wake on LAN (WoL) has the capability to communicate with computers that are powered off or in a low power mode. Wake on LAN Magic Packet is also called the WOL Packet that acts as the transmitter of the Wake up on LAN message. A device connected to the network can transmit the magic packet Wake on LAN message to wake up a target computer, eliminating the need to physically boot up a machine.
A network admin can perform a remote wake on local area network (LAN) using the Wake on LAN software by transmitting the magic packets to the target device. To do this, a Wake on LAN message is broadcast to all the machines in the network or subnet, including the target machine to be awakened. The Wake on LAN Packet is transmitted through the datalink layer by the WOL Software. The machines in low power mode that are enabled with Wake-on-LAN infrastructure will “listen” to the broadcast message. The machine boots up if the received WoL magic packet contains its MAC address.
Wake on LAN offers several advantages for network admins, that enables them to manage the network device booting schedules with ease. Some of the important capabilities of wake on LAN that makes using it essential includes,
Remote booting : In a large network with hundreds of devices to be managed, it is impractical to manually boot up or shut down devices. To overcome this hurdle, most network admins rely on wake on LAN. Enabling network admins to remotely boot up devices and monitor their status, Wake on LAN saves the foot work of manual booting.
Centralized control : Booting network devices becomes more difficult if the devices are physically distributed across different floors, or blocks within the organization. OpUtils' wake on LAN enables network admins to gain a centralized view of their network devices. Monitoring the device up or down statues from OpUtils'web console, network admins can easily boot up or shut down devices with a click.
Automating wake-up routines : Not all devices within a network require to be booted up or shut down at the same time. Different devices or groups of devices require different wake -up routines. OpUtils’ offers a Wake on LAN scheduler that enables you to create multiple schedules for a device, or group of devices, that require a periodic wake-up routine. This can be daily, weekly, monthly, or just once. The scheduler automates the monotonous task of periodic remote booting, and also provides visibility into the status of the scheduled wake up of different devices, in the WoL console.
Network admins can monitor the device status and trigger wake-up calls to network devices, right from their OpUtils' wake on LAN web console. They can monitor their wake on LAN processes with visibility into the status of the scheduled wake ups, individual devices, and device groups.
OpUtils offers features like port scanner, advanced IP scanner, IP address tracker, network scanner, and 30+ network tools such as IP tools ,along with Wake on LAN tool. These features give you full fledged network resource monitoring along with complete visibility into your IPs and switch ports.
