USB Keyboard Emulator for Linux OS 2.6 kernal

Hi everyone,

Well to start off I am new here and new to emulator software and devices so please bare with me if I sound a bit stupid. I am currently looking for a solution in which I hope someone can help me out with. Here's whats going on:

I would like a USB Keyboard emulator that works with a Linux OS 2.6 kernal. I would like to hook up 2 linux boxes via USB cable have one box run automated test scripts to the other linux box which contains an X windows application. Through out this process there is not supposed to be a physical keyboard involved, just the USB keyboard emulator

Can someone please let me know how this can be possible, or if this is even possible? Thank you all for you time, nvThisJaTTi :(
