apache+php chroot

I have chrooted apache+php but am having simple problems like not being able to exec uptime. uptime has been moved to /usr/serv/apache/usr/bin/uptime.. Well anyways heres my lil php line im tring to get running <?php passthru ( "uptime" ); ?> I get no errors from php, just doesnt show anything.. I realize it needs a shell to execute so /usr/serv/apache/bin/bash and /usr/serv/apache/usr/etc/shells is setup correctly. Would there be something that im missing? Im frustruated right now.. Its something to do with the chroot env. What am i missing?? Everything else seems to work fine if theres any more info you need me to give let me know. thanks Ryan ryanpek@swbell.net
