I give up! How can I set up my Linux box such that
any user can plot (via gnuplot, of course) to the
screen? At present, only root can plot because the
normal users "Can't get I/O permission."
I've done what was mentioned in the README.svgalib,
which is "chmod +s prog-name". I tried chmod +s
gnuplot, chmod +s octave, chmod +s /usr/local/lib/
everything else I could think of.
Users can, however, use gnuplot directly, which imples
to me that this has something to do with the pipe. Does
the setuid work through a pipe?
