We have a linux machine in our lab that is used for experimental purposes. And, every now and then, it crashes, and we can no longer log-in. So, we find ourselves having to manually push the restart button.

Is there a way to reboot a crashed linux system remotely?

Note: Doing this over the LAN would be the optimum solution. Otherwise, an affordable device that responds to network commands, and does an off/on to the power source directly would be good too.

It depends on your hardware. If it is a server, you probably can use some remoting feature for that (like iLo[^] on HP). Consult with your server vendor.
On some desktops there is vPro[^] that can be also used to control power state.
But these are not available for all hardware platforms. So if you are at the start of a project, try to purchase hardware with such remote control feature. If you want to use exisiting hardware without such feature, than you will need to purchase network controllable switch like OriginalGriff suggested.

:laugh: You can't reboot it over the network when it has crashed - for the simple reason that if it has crashed, it isn't talking to the network any more!

There are net controlled power switches though - this is one type:[^] but I'm sure there are others.
