Here where I work we have a little thing called a "Terminal Server" which allows admins to remotely reboot machines. Maybe Seti folks ought to consider getting some of these for those times when a glitch happens in the middle of the night and they need to "power fail" a server or array or whatever to get it to work again!

As a SysAdmin for a network I can explain that. You see sometimes servers just like home PC Hardlock and the only think you can do is push the power button. Sadly Terminal Services, Shutdown.exe, or PC Anywhere or Citrix Etc will not do that. There are only 3 solutions to that. You ***CAN*** get a card that will do that if your hardware is rated for such a card but those are generally VERY expensive. You can build a robot with a little arm and camera to do it. Or you have to wait for someone to be in front of the server...

I have an old Robbie the Robot I would donate though all the servers would have to be on the floor for it to work... :)

i have build a robot in lego for this purpose, it can't walk but it can push a little stick back and forward. Perfect for server power buttons... :-)

Hmm... don't know what kind of servers S@H is running on, but the machines *we* use have a special port in the back where we can "power fail" them. There is a CAT-5 cable connected between the "terminal server" and the server box. You dial into the terminal server appliance and somehow tell it to reset port x, which reboots the machine linked to the TS appliance. This is NOT a software solution. It's a hardware solution. That's what they need if this software is so buggy that it's going to end up hardlocking the servers!

I agree that a "robot" would also work well. Again with all the brains there at Berkeley, they oughta be able to build something that'll interrupt the power supply, one way or another, for 5 or 10 seconds, long enough to force a reboot! If that means building a robot to unplug and replug the power cord, so be it. If it means building a robot to push the power button, so be it. Just do something so that you can remotely reset the server!

APC the ups makers have a device that sits between the UPS and servers or other devices just for this job.
