Dear all, I have a cgi script, which uses some perl scripts in which i'm running iptables command using "system" function, like this: myfile.pl: ...... system("iptables -F FORWARD") ...... the cgi file is owned by root/root and is run by user nobody. myfile.pl is owned by root/root, and I've it setuid (chmod u+s myfile.pl ; chown root:nobody myfile.pl) to be able to run iptable commands, but it returns this error: ///// modprobe: Can't locate module ip_tables. iptables v1.2.11: can't initialize iptables table `nat': Permission denied (you must be root) perhaps iptables or your kernel needs to be upgraded. ///// what's the solution? thanks a lot afshin lame
