Once the magic packet is sent, the remote system will start to boot. When the server is not up, execute the following command from another machine which is connected to the same LAN. Interrupt:17 Finally, Switch ON the machine remotely without physical access TX packets:2170162 errors:0 dropped:0 overruns:0 carrier:0 RX packets:3179855 errors:0 dropped:0 overruns:0 frame:0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Note down the MAC address of the server that you wish to switch on remotely.Įth0 Link encap:Ethernet HWaddr 00:16:k5:64:A9:68 # apt-get install wakeonlan Note down the MAC address of the remote server Install the wakeonlan package in the machine from where you need to send the magic packet to switch on your server. $ /sbin/ethtool eth0Ĭannot get device settings: Operation not permittedĬannot get wake-on-lan settings: Operation not permittedĬannot get link status: Operation not permitted Install wakeonlan package on a different machine Note: You should execute ethtool as root, else you may get following error message. If not, use ethtool to set the g flag to the wol option of the NIC card as shown below. Enabling wol option on the Ethernet Cardīy default the Wake-on will be set to g in most of the machines. If Supports Wake-on is g, then the support for wol feature is enabled on the NIC card. Supported link modes: 10baseT/Half 10baseT/FullĪdvertised link modes: 10baseT/Half 10baseT/Full But after the first first boot you can use wakeonlan to turn it on, if the server gets shutdown for some reason.Ĭheck whether wol is supported on the NICĮxecute the following ethtool command in the server which you want to switch ON from a remote place. When the system crashes because of power failure, for the first time you cannot switch on your machine using this facility.wakeonlan package should be installed on the machine. You need root access to send magic packet. You need to send the magic packet from another machine which is connected to the same network ( LAN ).In most cases, by default wakeonlan is enabled on the NIC. Your NIC should support wakeonlan feature, and it should be enabled before the.You can use Wakeonlan when a machine is connected to LAN, and you know the MAC address of that machine.This article gives a brief overview of Wake-On-LAN and instructions to set up Wakeonlan feature. Also, If you have a server that don’t need to be up and running 24×7, you can turn off and turn on the server remotely anytime you want. Wakeonlan sends magic packets to wake-on-LAN enabled ethernet adapters and motherboards to switch on remote computers.īy mistake, when you shutdown a system instead of rebooting, you can use Wakeonlan to power on the server remotely. Wakeonlan (wol) enables you to switch ON remote servers without physically accessing it. This is a guest post written by SathiyaMoorthy.
