#!/bin/bash
echo -e 'shelltest:iptables -L'
iptables -L
<?php
exec("/usr/bin/sudo /var/www/html/shelltest.sh",$output);
print_r($output);
echo<hr />;
?>
这个对吗

F5已毁

再顶一顶

都说两句提示一下嘛

还有人提点建议吗～～～

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <unistd.h>
int main()
{
uid_t uid ,euid;
uid=getuid() ;
euid=geteuid();
printf("my uid :%u\n",getuid()); //这里显示的是当前的uid 可以注释掉.
printf("my euid :%u\n",geteuid()); //这里显示的是当前的euid
if(setreuid(euid, uid)) //交换这两个id
perror("setreuid");
printf("after setreuid uid :%u\n",getuid());
printf("afer sertreuid euid :%u\n",geteuid());
system("/sbin/iptables -L"); //执行iptables -L命令
return 0;
}

上面文件 /var/www/html/ip.c
gcc -o ip -Wall ip.c
chmod u+s ./ip
ll
-rwsr-xr-x. 1 root root 5323 3月 31 08:17 ip

<?php
echo '<pre>';
$last_line = system('/var/www/html/http/ip', $retval);
echo '
</pre>
<hr />Last line of the output: ' . $last_line . '
<hr />Return value: ' . $retval;
?>

可是 浏览器：ip/ip.php
只有这些。。。
