problem executing this shell command

[designxperts]

i'm trying to run this shell command from inside my php program

$output =  shell_exec('service dhcpd restart');
echo "<pre>$output</pre>";

this is the output i get:

Shutting down dhcpd: [FAILED]
Starting dhcpd:

that's it.... and when i run it from the shell directly it works fine.. any ideas??

Does the user that runs the web service have access to restart services?

yeah, i'm logged in as root... when i go to the shell and type the command everything works fine !?

[designxperts]

sorry, i didn't understand ... how do i know the user? the only user i know is the root and i think it's the one running the web service.

echo `whoami`;

Probably something like 'apache' or 'nobody'. If the answer is root then that would be Very Very Bad.

the user is apache how do i give it access to restart services?? and not just that but to execute shell commands as well??
