Hardware keyloggers are usually cheaper than a laptop, but I see where you're going.

Issue is that it could be very obvious, and there are far easier ways to grab or hack passwords. Such as the freeware known as Ophcrack.

Use this info at your own discretion, however.

 cheap and big. Very big.

True, but it's meant only as a temporary way to get a password, in my case

You are essentially still doing the same thing on both the computers. Ifyou have both the computers on, then since both receive the same info,you are just doing the same thing on both the computers

You dont even need a software to run the same command on multipleservers, a simple batch script can do that. But this is just not thesame thing. I mean this allows you to type and everything without havingto do anything else, using ssh you are just sending commands nothingelse :)

It doesnt even have to be like this all you have to do is plug in two keyboards and it works . Buy a Usb Keyboard and plug it in and it will work with your current keyboard. Good Luck. Robert

I had 4 USB mice and a PS/2 mouse hooked into my computer all at once to see which ran smoothest/I liked best, was quite fun

sounds very funny but if you want to know which is the best keyboard do the online typeing test any see when you get the best score.

You could do that, but the keyboard would only work on one machine at a time. With this hack, you can plug one keyboard into two different computers at the same time such that both machines receive the exact same keyboard input at the same time. This can be useful when testing two different machines and you want to ensure that each is receiving the exact same input. USB won't allow a device to be connected to multiple hosts, but a PS/2 device will work in this sort of configuration. By using the USB-->PS/2 adapter, you are hacking around the USB "single-host" limitation. This is a hack and there are undoubtedly many downsides to this method, but for the writer's purposes (see the last step) it seems to work rather well. I would suspect that you wouldn't need the PS/2-->USB cable if the machine had a PS/2 port that you could plug the keyboard into.

????????????? i am confusled

For this Instructable, the converters are necessary. The goal of this 'ible was to use one keyboard to control two machines simultaneously, and this is only possible when using the USB-->PS/2 and PS/2-->USB adapters. The keyboard would work without the adapters, but you would only be able to plug it into one computer at a time (which defeats the point of this project).

I am still a little bit confused but okay if you say so!

I'll put it this way. It is essentially a ps2 keyboard right? Computer dont mind sending multiply signals for a ps2 keyboard. However, it is infact a usb keyboard to start. This is only because we know which wires are which, but a usb will not send multiply signals and would end in a clusterduck.

Ahahahahaha, Evil. Smooth man. I dont mind dictatorships, cause i aint in them and i can admire they're power from over here (AUSfag)

I'm doing it right now just to test. Two USB work, as do a USB and a PS/2.
