I've been looking to ways to get some sort of keylogging going at my lfs box.
I was thinking about catching the io form bash and put it into a logfile,
my first attempt is this:
bash 2>&1 | tee /somewhere/log.file
It doesn't add to the security of the box, but then you can see what the
hacker was doing (unless he finds it and deletes the logfiles)
