Someone asked me if i can make a perl scripts that can change the ip address based on time interval, say he want ip address used within one hour, if done next ip address will be used within next one hour..and so on. when it came to highest number of ip address in array, they will be reset back to the start. first i suggest him to look at the articles i wrote. But then i decide to write Perl script which was made for the purposes mention above.

here we are..

Postfix section: inet  n       n       n       -       0      spawn
          user=nobody argv=/etc/postfix/

ip1  unix -       -       n       -       -       smtp
          -o syslog_name=postfix-ip1
          -o smtp_bind_address=

ip2  unix -       -       n       -       -       smtp
          -o syslog_name=postfix-ip2
          -o smtp_bind_address=

ip3  unix -       -       n       -       -       smtp
          -o syslog_name=postfix-ip3
          -o smtp_bind_address=

ip4  unix -       -       n       -       -       smtp
          -o syslog_name=postfix-ip4
          -o smtp_bind_address=

transport_maps = tcp:[]:2527 = 3600s

A web badge is a small image or text used on websites to promote web standards, products used in the creation of a web page or product, to indicate a specific content license that is applied to the content or design of a website, to comply with an application’s terms of service, to encourage your visitors to check your social network status, or even to display visitor’s informations. such as ip address, user agent, hostname etc.

Today’s story, we’ll make a badge for visitor’s ip address using php and javascript. This badge, for an example:

create a php script called ipaddr.php as follows

if ( isset($_SERVER["REMOTE_ADDR"]) )    {
	$ip=$_SERVER["REMOTE_ADDR"] . ' ';
} else if ( isset($_SERVER["HTTP_X_FORWARDED_FOR"]) )    {
} else if ( isset($_SERVER["HTTP_CLIENT_IP"]) )    {
	$ip=$_SERVER["HTTP_CLIENT_IP"] . ' ';
$IpAddr = $ip;

if (typeof(v_ip_BackColor)=="undefined")
  v_ip_BackColor = "white";
if (typeof(v_ip_ForeColor)=="undefined")
  v_ip_ForeColor= "black";
if (typeof(v_ip_FontPix)=="undefined")
  v_ip_FontPix = "16";
if (typeof(v_ip_DisplayFormat)=="undefined")
  v_ip_DisplayFormat = "You are visiting from:<br>IP Address: %%IP%%";
if (typeof(v_ip_DisplayOnPage)=="undefined" || v_ip_DisplayOnPage.toString().toLowerCase()!="no")
  v_ip_DisplayOnPage = "yes";

v_ip_HostIP = "<?php echo $IpAddr ?>";

if (v_ip_DisplayOnPage=="yes") {
  v_ip_DisplayFormat = v_ip_DisplayFormat.replace(/%%IP%%/g, v_ip_HostIP);
  document.write("<table border='0' cellspacing='0' cellpadding='5' style='background-color:" + v_ip_BackColor + "; color:" + v_ip_ForeColor + "; font-size:" + v_ip_FontPix + "px'><tr><td>" + v_ip_DisplayFormat + "</td></tr></table>");
