If you have safe mode on, you can set various things to stop this. One is safe_mode_exec_dir. You can specify a directory with binaries the users can run. Anything outside of that PHP won't run. Just set it to a path with no binaries (and no write access fromusers) and they won't be able to run outside programs unless you let them. You can also put some funcitons in disable_functions, such as system() and exec(), poper(), proc_open(), passthru(), and shell_exec(). Disabling shell_exec() also disables backticks (`) (I think). -- paperCrane --Justin Patrin-- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
