Yep, it's a permissions problem. For starters, when the scripts are run through your web site they will run as the user that your web server runs as (nobody or apache or some such) and that user will typically have limited permission to do much of anything. If you're doing stuff that is normally only accessible to root then you'll have problems. For starters, the SUID bit usually doesn't work on shell scripts - this is a security thing. I've not really considered how to get around this but you might look at what Webmin does as it does plenty of 'root only' stuff from a web browser. Off hand, one solution might be to create the shell script from your web page but then not try and execute it. Then have a cron job (running as root) that will examine the contents of a directory and run the scripts accordingly. I can think of a number of security problems with this so you'd want to be very careful what you let people do in this environment.
