Title: Network interfaces are not correctly brought down on halt, disrupting Wake-on-LAN Status in ifupdown package in Ubuntu: Triaged Status in upstart package in Ubuntu: Confirmed Status in ifupdown source package in Precise: Triaged Bug description: I found the workaround (and proof) for this bug is posted here: http://confoundedtech.blogspot.com/2011/06/enable-wol-on-ubuntu-hp-microserver.html The relevant info is below ===== To get WOL to work the ethernet interface must be properly brought down as part of the system shutdown. This should be performed as part of run levels rc0 and rc6, noting that Linux typically has 7 different run levels (or operating modes): rc0.d - System Halted rc1.d - Single User Mode rc2.d - Single User Mode with Networking rc3.d - Multi-User Mode - boot up in text mode rc4.d - Not yet Defined rc5.d - Multi-User Mode - boot up in X Windows rc6.d - Shutdown & Reboot A simple script can be created to bring the ethernet interface down properly at shutdown: sudo vi /etc/rc6.d/wol_poweroff.sh It may contain: #!/bin/bash ifconfig eth0 down poweroff Change the script's permissions to make it executable: sudo chmod 755 /etc/rc6.d/wol_poweroff.sh Copy the script to work on system halt as well: sudo cp /etc/rc6.d/wol_poweroff.sh /etc/rc0.d/wol_poweroff.sh Change permissions to make it executable: sudo chmod 755 /etc/rc0.d/wol_poweroff.sh Job done. To test power down the machine, sudo shutdown now or sudo poweroff , and use your favourite WOL tool to send a magic packet.
