note 95858 added to function.exec

Anyone know about some limitation of php 5.1.2 about the exec() function? Im testing a Nmap frontend made in PHP in two servers, one running Suse Server 10 with php 5.1.2 and the other running OpenSuse 11 with php 5.2.9...the server with php 5.2.9 was able to execute the script with exec function with no problems, but i can't make my php 5.1.2 run a exec() command. I`m not using safe mode or any disabled function at php.ini, permissions and owners are the same...Could anyone give an idea from where to start? ---- Server IP: 192.41.40.227 Probable Submitter: 189.20.98.70 ---- Manual Page -- http://www.php.net/manual/en/function.exec.php Edit -- https://master.php.net/note/edit/95858 Del: integrated -- https://master.php.net/note/delete/95858/integrated Del: useless -- https://master.php.net/note/delete/95858/useless Del: bad code -- https://master.php.net/note/delete/95858/bad+code Del: spam -- https://master.php.net/note/delete/95858/spam Del: non-english -- https://master.php.net/note/delete/95858/non-english Del: in docs -- https://master.php.net/note/delete/95858/in+docs Del: other reasons-- https://master.php.net/note/delete/95858 Reject -- https://master.php.net/note/reject/95858 Search -- https://master.php.net/manage/user-notes.php
