I am working on a system recoverey tool that needs
to capture all keystrokes of the machine, are there
anyway to do this under linux? I know there are some
commercial tools for Windows. But is there anyway to
do this under linux?
I can have access to root and everything. Is it possible
to pipe stdin to some places and record it before feed
back to (a faked) stdin? This needs to work under X also.
Thanks a lot.

I would suggest insert some code to the keyboard device driver, or nearby.
