Sorry - I misunderstood your concern. Yes, it gives the user permission to do whatever he wants (which isn't quite the same as the right to do whatever he wants - but the difference would take some explaining). And yes, as I mentioned, the user could change the sudosh log files, and /etc/sudoers, and so on. I generally take the view that if you can't trust the users with root privileges, you are in for a very difficult time - usually stated in the more absolute form "root can do anything", where anything includes erasing or replacing the o/s (though the reboot can be tricky over a network). It might be over-simplistic as a view; it isn't too far removed from the truth. -- Jonathan Leffler ([email protected]) STSM, Informix Database Engineering, IBM Information Management Division 4100 Bohannon Drive, Menlo Park, CA 94025-1013 Tel: +1 650-926-6921 Tie-Line: 630-6921 "I don't suffer from insanity; I enjoy every minute of it!"
