Ok... several questions: first, you didn't copy *mine*, did you? You got
one out of your /var/log/messages? Second, you ran it from a command line,
on the machine, correct? <looks at the manpage> Ok, I guess you can run it
from the GUI, but if you're not on the console, you have to have X
forwarding enabled in sshd, and then log in from a system running X with
ssh -X or ssh -Y.

I do most of what I do, as do most sysadmins I know, from the command line.
