Use curl to forge an IP address


Copy the IP address I found to the txt file, and sed and awk processed it. I will share my awk processing script:

#! /Bin/awk-f # BEGIN {FS = ""; count = 0 ;}# running {iparr [count ++] = $0 ;} # END {printf ("<? Php \ n "); printf (" $ iparr = array (\ n "); for (I = 0; I <count; I ++) {printf ("'% s' =>' % s', \ n", iparr [I], iparr [I]);} printf ("); \ n ");}

CURL usage

<?php   require_once dirname(__FILE__) . "/iplib.php";      $req_url = "test.com";      foreach ($iparr as $forward => $cip) {          $ch = curl_init();          curl_setopt($ch, CURLOPT_URL, $req_url);     curl_setopt($ch, CURLOPT_HTTPHEADER, array(         "X-FORWARDED-FOR:$forward",         "CLIENT-IP:$cip"     ));     curl_setopt($ch, CURLOPT_REFERER, 'http://blog.csdn.net/');     curl_setopt($ch, CURLOPT_HEADER, 1);          curl_exec($ch);          curl_close($ch);   } 


Defects
Many servers generally use $ _ SERVER ['remote _ ADDR '] to obtain the client's real ip address, which is determined at the transport layer and cannot be modified through CURL, well, it seems that I have not helped my friends do this thing successfully, but record it.
