Hi,
if you want to run an external program with a bash command (seems like
that's what you're trying to do) exec is not the right function for
you; with exec you can run python modules.
Try something like:

os.system("home/eirik/ppp-skript --argument")

instead or if you want to get the output of your program try

xyz = commands.getoutput("home/eirik/ppp-skript --argument")

Did that help (maybe I have not really understood your problem)?

Cheers
