Avoids power spikes by staggering wake-up events. Includes tools to scan network for hosts, ip and MAC addresses. Supports complex network environments with subnet directed broadcasts. Debugging tool displays incoming WOL packets. You can see all of the filters for the describe-instances command in the documentation. User configurable network interface for WOL (new) Ability to auto-start with Windows. Ensure that WOL is enabled in the BIOS under Power Management settings. If there is no link light, then there is no way for the NIC to receive the magic packet to wake the system. The second is the -filters option which, as the name implies, lets you filter the results based on a lot of criteria. Confirm that the link light remains on when the system is powered off. One is the -query option which lets you pull data out of the returned JSON data. This uses two very powerful features of the CLI. | xargs aws ec2 start-instances -instance-ids "Name=tag-key,Values=WakeOnLAN" -output text filters "Name=instance-state-name,Values=stopped" If you have a sufficiently bloaty netcat (BusyBox can have one of two nc. If your BusyBox doesn't have it, consider recompiling BusyBox to include it. The ether-wake command in BusyBox is exactly what you're after. Its one command line but I have wrapped for formatting. You need something that's capable of sending an Ethernet packet that will be seen by the device you want to wake up. Here is how to do the same on one line, all be it only within a single region. If you run it make sure it has privilege to perform the actions, a role on an EC2 instance makes this easy. The script simply goes through all of your instances in each region, finding those that have the WakeOnLAN tag and that are stopped, then starts them. How would you approach this in AWS? You can fire of an API call to start any instance, but what if you wanted to make this easier? Simply tag your instances with an identifiable tag, such as "WakeOnLAN" and then run the following script (I prefer Ruby).ĪWS.regions.sort_by(&:name).each do |region| But it also shows not thinking of infrastructure as code. Is Wake-on-LAN supported in Amazon Web Services.
