Have you tried to 'su -' to nobody (or whomever your server is running as) and run the command that way? Have you tried to run the script from the command-line and see what that yields? On a side note, you may want to ensure that you are using Taint for all of your CGI scripts when they interact with the OS. Thanks, JJ -- J. J.

If we lose one freedom in a thousand, we become completely subjugated.
