Well, I fear the day people find out the syscalls necessary to do this breach! In the maentime I think sysadmins should note that they should *REMOVE* THE OLD COPY OF THE PROGRAM! It is probably still in your authorized area ind /install/ri.apollo.os.v.10.2/ - and you know the rest of the patch. This will still allow anybody with access to a cartridge tape, a disk, email, the keyboard or just about anything else allow to intrude - but not quite as easily! bye, mike ____ ____ / / / / / Michael K.
