Yes. Sorry that wasn't clear. > How are you changing the uid and gid of your script? IIRC you have to > set the effective user id with os.seteuid() and os.setegid(). I'm changing the uid and gid in the daemon (which runs with root permissions until the fork and uid/gid change). The uid and gid are confirmed by printing os.getuid() and os.getgid() in the script. > Christian -- http://mail.python.org/mailman/listinfo/python-list
