Dell PowerEdge 750 (Wake-On-Lan)

wake-on-lan

How do I make (WOL) Wake-On-Lan work ? I've tried everything now, all I see is green blinking power light when server is off. There is no additional options for "Wake On Lan" or power state. Any ideas ? Does this Dell PowerEdge 750 support WOL at all ?

WOL is based on motherboard and NIC compatibility. Both the motherboard and NIC have to support WOL capabilities. You'll also need an application or utility that has the capability of sending a WOL signal/packet.

Without knowing the BIOS version, I can't say for sure, but Dell's support website indicates it does (http://en.community.dell.com/support-forums/servers/f/1466/t/7612115.aspx). You'll need to reboot your system and boot into your BIOS to confirm.

After that, you'll need to boot the system into the OS and confirm the NIC's WOL capabilities are enabled. In Windows, it's an option under the device configuration; generally under Device Properties > Power Management > Wake On Lan.

Lastly, the application or utility you'll need to take advantage of WOL needs to capability to send a "magic packet". Some routers have this capability built in to a management page; you just need to configure the device as a WOL device. After it's configured, it's as simple as logging into the management interface and pushing a button.

There are also WOL apps available in all flavors online that you can run on your desktop or on your mobile device.

You need to send the packet to the broadcast address of the network. You can't send it to 192.168.1.127, because the PC is powered off and so this IP is not owned/bounded by him. Set it to 192.168.1.255

You could use /etc/rc.local or some system boot scripts, but this wouldn't be the best way to do it. On startup your network interfaces are configured, sure, but there are other times when your network interfaces may be brought up or down and you will need this executed during those times.

You want to edit /etc/network/interfaces:

You should have a line like:

iface eth0 inet static

Underneath that, indented further, you want to create a post-up and post-down commands e.g.

iface eth0 inet static
    post-up /usr/sbin/ethtool -s eth0 wol g
    post-down /usr/sbin/ethtool -s eth0 wol g

Obviously, replace eth0 with the relevant interface if different.

See interfaces(5) for more information on post-up and post-down commands
