Two ideas come to mind: Use something like RFC931 authentication to verify users (although RFC931 is really an identification protocol, not an authentication protocol). Make a setuid news reader that only people in a special group can execute, and have the reader bind to a reserved local port, and have the NNTP server check for a reserved remote port. Both of these ideas have plenty of problems (an understatement :-) ), but they would work (at least, I can't see any problems). --Ken
