It start a script that forks and runs execve mplayer to record KUSC

In mail I find the output of the mplayer run. It is huge, filled with
his inane % buffer filled numbers. But at the very end is the answer

That brings up the question: why are you receiving mail as root? You
should have all root and administrative mail forwarded to some real
user. If you read mail as user, then any virus or worm has access to
the entire system, as opposed to just the user's files. On my system
(with exim) I have the /etc/aliases file to redirect all root and
administrative mail to my user mailbox. I'm not sure, but I thought
that was one of the installation questions when I first installed
That's a good point. I never used mail until a few months ago, when
WordPress and reportbug needed to use it. Exim is configured for no
local mail but smarthost.
