April 20, 2014 Linux, Localhost, PHP, Ubuntu

In a post, I told how to create a localhost website using Apache server in Ubuntu. It worked on all versions up to Ubuntu’s 10.10th version. But on Ubuntu versions 11.04 and the versions released after it, there were some changes to the Apache server.

April 15, 2014 Linux, PHP

In the recent post, I gave the default TTL value of different devices. As you can see, when you ping a host you can roughly identify the operating system the remote server’s running.

Bot Page

Our crawler leaves a mark on every pages it visit. In other words a custom User Agent String goes with each requests to web pages. In the previous part, we set the user agent string as :

DingoBot (http://search.subinsb.com/about/bot.php)

We add a URL with it, because if the site owner sees this in their stats, they would think “what’s that ?”. So, to answer that question we add our bot info link. Also to promote our site.

index.php

The main page of our Web Search is index.php. It has a simple design and is not very advanced as Yahoo or something else.

<html>
 <head>
  <?head("", array("index"));?>
 </head>
 <body>
  <?headerElem();?>
  <div class="container">
   <center>
    <h1>Web Search</h1>
    <form class="searchForm" action="search.php" method="GET">
     <input type="text" autocomplete="off" name="q" id="query"/>
     <div>
      <button>
       <svg class='shape-search' viewBox="0 0 100 100" class='shape-search'><use xlink:href='#shape-search'></use></svg>

     </div>
     <p>Free, Open Source & Anonymous</p>

March 18, 2014 PHP

Zip file downloading is used by websites. The most important and popular of them is WordPress. They use Zip files for downloading plugins, themes and even their versions.
