thanks for the response andrews.

Why do you suspect of permissions issue?


I suspect permission issue because when i run the code as root user in 
the terminal it is generating the output file.

if i run the same code in the browser it is not generating the output 
files .

Are you trying "su www-data" and then running the exact same command?


i have given www-data:www-data permission to my code as well .
still it is not working.

i will try to explain once again :

i have a w3af script for w3af crawl -
http-settings
set timeout 60
back
plugins
crawl web_spider
crawl config web_spider
set only_forward False
set follow_regex .*http:/localhost.*
set ignore_regex (?i)(logout|disconnect|signout|exit)+
back
output text_file
output config text_file
set output_file /var/www/wsafe1/scanreports/crawl_localhost_222222222.txt
set verbose False
back
back
target
set target http://localhost:80
back
start
exit


i have called this script in my php code i.e :

<?

$w3af_script="/var/www/wsafe1/crawl_localhost_222222222.w3af";
echo "Start of code ::*****";

if(is_readable($w3af_script))
     {

         echo "\n"."ready to execute the script in the terminal";

         `python /var/www/wsafe1/tools/w3af/w3af_console -s $w3af_script`;

     }


if(is_readable("/var/www/wsafe1/scanreports/crawl_localhost_222222222.txt"))
{
     echo "-----OOOOOOOOOOOoutput file got generated ";

}
else
     echo "-----FFFFailed to generate the outpt file ";


?>



now problem is , i am not getting the file generated if i run the code 
from the browser or by normal user.

root user is able to generate the files using the same code .


please help me out !!!!!
