<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">There are several benefits of using a transparent proxy. First of all, for end users, a transparent proxy can enhance their web browsing performance by caching frequently accessed web content, while introducing minimal configuration overhead for them. For administrators, it can be used to enforce various administrative policies such as content/URL/IP filtering, rate limiting, etc.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">A proxy server acts as an intermediary between a client and a destination server. The client sends requests to the proxy server which then evaluates the requests and takes necessary actions. In this tutorial, we will be setting up a web proxy server using Squid, which is a robust, customizable and stable proxy server. Personally, I had administered a Squid server with 400+ client workstations for about a year. Although I had to restart the service about once a month in average, CPU and storage utilization, throughput and client response time were all great.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">The Preboot eXecution Environment (PXE, sometimes pronounced as pixie) specification describes a standardized client-server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients. On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard. Given fast and reliable local area networks (LANs), PXE is the most frequent choice for operating system booting, installation and deployment.</span></span></div>

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">OpenVAS (Open Vulnerability Assessment System,the name of the fork originally known as GNessUs) is a framework of several services and tools offering a vulnerability scanning and vulnerability management solution.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">All OpenVAS products are Free Software. Most components are licensed under the GPL.</span></span><br />

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">OpenVas began, under the name of GNessUs, as a fork of the previously open source Nessus scanning tool after Tenable Network Security changed it to a proprietary (closed source) license in October 2005. OpenVAS was originally proposed by pentesters at Portcullis Computer Security and then announced by Tim Brown on Slashdot.</span></span><br />
<br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">OpenVAS is a member project of Software in the Public Interest.</span></span><br />

<div dir="ltr" style="text-align: left;" trbidi="on">

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">X-Cart is a PHP/MySQL based secure shopping cart software with open source code.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b><u>X-Cart:</u></b></span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">1) To start you just need to install the basic pack. Then you can extend it with skins/add-ons with one click right from the admin back end.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">2) When you need to upgrade/update the store, click just one button and the software handles this automatically.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">3) When you need an extra feature you can have us build it or hire a developer you like.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">4) When you need assistance, you can choose between community, which is very active by the way, and official technical support.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">5) When you need to accept credit cards right on your website, you simply sign up for X-Payments, set it up and go.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">6) There is a one time fee for the license.</span></span><br />
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b><u>The latest stable version of X-Cart is 5.2.13 and it requires:</u></b></span></span><br />

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">At this step, you need to define the email and password for your store's administrator profile. Once you are done with that, X-Cart 5 will send a notification to the email address you have specified along with some service info.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRlxHUBY4g0iyDC3o7GCyztKsmYhYpHW8xL8F5zuSFLCyG4CePG0usPht-Spsvpmo_QuPNRLdWFVPVk3-_wenBDe7v8Nhr7MQvST-xC8FoDVrcfPxQ6xeH28ZssH_sM2vyg2WOwwKADy8f/s1600/xc5_installation_step2_hackthesec.co.in.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRlxHUBY4g0iyDC3o7GCyztKsmYhYpHW8xL8F5zuSFLCyG4CePG0usPht-Spsvpmo_QuPNRLdWFVPVk3-_wenBDe7v8Nhr7MQvST-xC8FoDVrcfPxQ6xeH28ZssH_sM2vyg2WOwwKADy8f/s1600/xc5_installation_step2_hackthesec.co.in.png" /></a></div>
<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Now the installation wizard will check whether your server meets the system requirements for X-Cart 5. It will report if the requirements are not met. If everything is OK, you will be automatically redirected to the next step.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">At this step you need to define the basic settings of your X-Cart 5 installation. Typically the page looks like the snapshot below:</span></span><br />

<span style="color: #222222; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Let's walk through the settings you need to adjust. The first group of settings on this page is as follows:</span></span><br />
<br />
<ul style="text-align: left;">
<li><span style="color: #222222; font-family: verdana, geneva, sans-serif; font-size: 15px; line-height: 26px;"><b>MySQL server name:</b> The name of your MySQL server. In most cases, it is localhost. If it is different, your host has likely notified you about it.</span></li>
<li><span style="color: #222222; font-family: verdana, geneva, sans-serif; font-size: 15px; line-height: 26px;"><b>MySQL database name:</b> The name of the database that will be used by your X-Cart 5 store (You have created this database earlier at the step "Create an empty database").</span></li>

<li><span style="color: #222222; font-family: verdana, geneva, sans-serif; font-size: 15px; line-height: 26px;"><b>Install a sample catalog:</b> Whether you want to have sample data in your X-Cart installation for you to experiment with. If this is your first experience with X-Cart 5, we strongly recommend enabling this check box.</span></li>
</ul>
<br />
