Server system? (Maybe Backup System)

[tosse12]

Hey guys!

Okey, now you would think: "WTF? Server system? what do that tardy mean?"

Well I am trying to figure out how I can make a computer start up when the other computer crashes / shutdown.
Can give you an example:

Computer 1 are hosting Open Tibia Server and Counter Stirke server.
When the Computer 1 shutsdown / crashes ( I mean the computer not the servers clients)
Computer 2 will start up.

I want to know how I can make another computer start up when the other computer crashes / shutdown.

Note: I don't care about the Server Clients / Softwares I am talking about the computer!

Hmm, something like ping request and if 1st server doesn't respond, run second? Ya, but how run second then?
Maybe something like power switch (fuse? ;p) that'd check if 1st machine is running and if not, send power to 2nd?

Yea, I know that there are some network cards that have that support:

If getting ping at port 10 (EXAMPLE)
then turn on computer

BUT
The problem is.... that how to tell the other computer if the main computer shutsdown?.
Like:

Comp 1 = Main comp with OT server
Comp 2 = Second backup comp with OT server
Comp 3 = Website / Database / (wakeup the Comp 2 if Comp 1 don't respond)Software

This is a little project my team are trying to solve

Anyone who have any idéa of how this could work?

You can probably do this with either bash scripting or a simple server / client application.

If you know C++ you could easily do this with a socket application that send a ping to comp1 ever lets say 30sek and if it doesn't respond it will start up those 2 application

I know a friend of mine did it in our C++ class
