I don't believe it can be done reliably, because there are to many different situations one can run into. The goal of FreeBSD is to make it easy to do powerful things, not easy to restrict users from doing powerful things. You can set the maximum number of processes (see the login.conf man page) for classes of users, but that's not the same thing at all. It takes two processes just to log in. Running one command means you've got three processes. Running a simple pipe involves one process for every command in the pipeline, none in the background. Setting an arbitrary process limit high enough to allow reasonable shell scripts to run will allow lots of processes - which could also be used as background processes. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
