note 95177 added to function.shell-exec

i am trying to implement the route command from linux with php. i have busted my brains for some days now, trying everything on the net (i will give some examples below) but still couldn't get it to work. $add = shell_exec("/sbin/route del 192.168.183.5"); echo route del 192.168.183.4; $defaultRoute = shell_exec("route add 192.168.183.8 gateway 192.168.183.2"); all these examples i have found on the web and tested but php still doesn't do anything. i can run the route command and the see the IPs listed there but i cannot use del/add to modfy them. i am using fedora 6. can anyone please help, i am a little desperate about this project? ---- Server IP: 59.162.86.123 Probable Submitter: 79.116.225.221 ---- Manual Page -- http://www.php.net/manual/en/function.shell-exec.php Edit -- https://master.php.net/note/edit/95177 Del: integrated -- https://master.php.net/note/delete/95177/integrated Del: useless -- https://master.php.net/note/delete/95177/useless Del: bad code -- https://master.php.net/note/delete/95177/bad+code Del: spam -- https://master.php.net/note/delete/95177/spam Del: non-english -- https://master.php.net/note/delete/95177/non-english Del: in docs -- https://master.php.net/note/delete/95177/in+docs Del: other reasons-- https://master.php.net/note/delete/95177 Reject -- https://master.php.net/note/reject/95177 Search -- https://master.php.net/manage/user-notes.php
