Thanks for the response.
Firstly, I have "Wake on LAN" enabled in the BIOS.
Secondly, rather to my surprise the ethernet light goes off when I "Hibernate" (I should confess at this point that I am running Centos-5.3 on this machine, but thought that I was more likely to get a helpful response on the Fedora list!) but stays on when I shutdown.
In neither case does ping or (attempted) ssh have any effect. How exactly is one meant to "wake from LAN".
One uses Magic Packets. http://en.wikipedia.org/wiki/Wake-on-LAN
To do this, first install a wol client on another machine to broadcast the wakeup: # yum -y install wol
Then read about the options: http://linux.die.net/man/1/wol
Then one wakes the target machine...
