Counting Keystrokes in Linux.

Shak · 12-25-2002, 05:21 PM

Hi,

Im looking for a way to count the number of keys pressed on a Linux system both from X and in X applications and in terminals.

I am planning a project in C/C++ for this, hopefully to be a nice learning project for me

Does anyone have any idea if the keyboard presses can be read anyway?

Thanks
Shak

I don't know exactly what you want to do, but the stdin stream is a pointer to a FILE structure, and by default the standard input is usually the keyboard device, so yes keyboard presses can be read. This is in C of course. I don't know anything about C++.

I'm not quite sure how to do something like that, but if I understand correctly, you want to make a program that captures every keystroke entered on your computer, right?

Normally such thing is never needed, unless you want compromise a system. What are you making? Some sort of trojan horse keyboard sniffer?

Anyways, if you want to do that, I guess you'll have to make some sort of kernel-module, since this is about breaking system security anyways....

Im not any kind of hacker, I dont want to capture what the keyboard strokes are, just when a button is pressed I want a counter to increase.

Its for a project called Project Dolhin which has a website at http://project-dolphin.net Ill have a look into the possibility of a kernel module (would certianly be a learning experience)

Check out Snoop, it's for BSD but download the source and check out the code and then you will se how they did it
