Remotely wake from sleep

    Ok, so I was working on a remote machine and needed to reboot. But I stupidly ran 'shutdown -s' instead of 'shutdown -r' and now I can't get the damn machine (which is 8,000km away) to wake from sleep. Any hints on how I might do that? I have the IP and MAC address.

    I'm working on a mac btw, but thought this might be the best place to ask...

    Does the machine have some kind of remote serial console ?

    Most of our machine have RSC's, which allow me to directly connect to the console of the machine so I can send breaks etc to the OS

    Unfortunately not. Some of our machines are on PDUs but not this one :(

    if the nic supports it (nearly all modern network cards do) you can use wakeonlan to turn it back on. In Ubuntu it's just "wakeonlan <mac address>". In windows you can download a 'wol' utility. There will be a similar utility for macs - maybe ask in the Mac forum?

    You have to be on the same network unless you have a WOL proxy to do it from outside.

    Low tech solution - ring someone in the datacentre, and ask them to push the button?

    I did find a Perl utility called wakeonlan but it didn't do the trick. Probably a networking issue.

    Unfortunately everyone who works there is in bed right now. Oh well, it can wait a couple of hours.

    Thanks everyone.

    Yup WOL works on layer two so chances are the magic packet didnt leave your network.
