Exec() denied read on Apache (fedora core 3)

Hi, I've been trying to execute some system commands and print back the output on the webpage. I found the following code to do so, however, it is not working. <?php echo exec('whoami'); ?> I get following errors in my /var/log/messages Dec 24 12:03:34 melville kernel: audit(1103889814.948:0): avc: denied { read } for pid=13794 exe=/usr/sbin/httpd name=sh dev=hda2 ino=670441 scontext=root:system_r:httpd_t tcontext=system_u:object_r:bin_t tclass=lnk_file Apache server is ran by user apache and the .php file is also owned by user apache. Apache is not running in Safe_Mode safe_mode Off Off safe_mode_exec_dir /var/www/html/sh /var/www/html/sh safe_mode_gid Off Off safe_mode_include_dir /var/www/html /var/www/html However, i tried to switch on the Safe_Mode but that wasn't any good either. Any idea how can i get it work? Thanks, Zia
