http://serverfault.com – I am experiencing a very annoying and mysterious behavior when sending magic packets (for Wake On LAN) shortly after pinging an Intel 82579LM GigaBit Ethernet Controller (the onboard ethernet controller of the Intel DQ67SW motherboard). So basically if I send an icmp echo request and wait a time dt before sending a magic packet I will experience the following: dt < 1 second: The computer will not wake due to the magic packet dt >= 1 second: The computer wakes as it is suppose to due to the magic packet This script is a minimal implementation of the scenario I am talking about: #!/bin/s (HowTos)
