Pursuant to the discussion of how to restrict the newsgroups that certain users can access, I have posted the PRUDE code I promised to news.software.b. This code is sufficient to keep the casual user out of certain groups. A user who understands anything about UNIX can get around it very easily by just finding the spool directory and reading the articles directly. Lemme see now, if I make the news directories 700 and run the news programs setuid, and stick a setuid(getuid()) in the code for shell escapes... John Opalko uw-beaver!tikal!mcgp1!newsadm " " " !jgo
