Is it possible that os.system and os.path.walk are being denied for
security reasons? After all, those functions can be set up to do
absolutely anything to your system, and giving access to them to a CGI
script is a major no-no from a security standpoint.
What exactly are you trying to do from your CGI script? You might want
to think about alternative ways of doing it. And especially if you're
handling any user-supplied data, think *long* and *hard* before passing
any user-suppied data as a parameter to something like os.system!
