Additionally, ejabberd can run under Microsoft Windows.

How to Install and Configure Ubuntu LTSP Server

<div dir="ltr" style="text-align: left;" trbidi="on">
<b><br /></b>
<b><span style="color: red; font-size: x-large;"><u><i>Install and Configure <a href="http://www.hackthesec.co.in/search/label/Ubuntu" target="_blank">Ubuntu </a>LTSP Server</i></u></span></b><br />
<br />
<span style="font-family: Lato, Arial, sans-serif; font-size: large;"><span style="line-height: 28.8px;"><b>Linux Terminal Server Project (LTSP) </b>is a free and open source terminal server for Linux that allows many people to simultaneously use the same computer. Applications run on the server with a terminal known as a thin client (also known as an X terminal) handling input and output. Generally, terminals are low-powered, lack a hard disk and are quieter and more reliable than desktop computers because they do not have any moving parts.</span></span><br />
<span style="font-family: Lato, Arial, sans-serif; font-size: large;"><span style="line-height: 28.8px;"><br /></span></span>
<span style="font-family: Lato, Arial, sans-serif; font-size: large;"><span style="line-height: 28.8px;">Improving access to computers becomes less costly as thin client machines can be older computers that are no longer suitable for running a full desktop OS. Even a relatively slow CPU with as little as 128 MB of RAM can deliver excellent performance as a thin client. </span></span><br />

How if we can open the on demand and close the port when it’s not used? Sounds interesting. Now we can do it using knockd application.</div>

Knockd is a port-knock server. It listens to all traffice on an ethernet (or PPP) interface, looking for special “knock” sequences of port-hits. (Source : <a href="http://www.zeroflux.org/projects/knock" style="outline: none; text-decoration: none;" title="knockd">http://www.zeroflux.org/projects/knock</a>)</div>

<u><span style="color: #0b5394;">How it works</span></u></h1>
<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
Every application needs a port as a “door” for “listening” requests from other clients. This port usually on open state or close state. There are a lot of ports that available on the server. But there are some ports that agreed by consensus, such as <a href="http://www.hackthesec.co.in/search/label/SSH" target="_blank">SSH </a>(22), Web (80) and <a href="http://www.hackthesec.co.in/search/label/ftp" target="_blank">FTP </a>(21).</div>
<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
A basic rule of server security is to open only used ports and close the rest. You may have some ports that are sometimes used and sometimes not. Leaving those ports open while is not being used is not recommended.</div>
<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
When you install knockd, you can let the client “knock” the server with pattern. The knocking sequence can be custom by you. So this knocking pattern will be unique to each other. If the pattern is match, then the port you need will be opened for a period of time and the request can enter your server.</div>
<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
Once you have done with the application, you can close the port manually or automatically.</div>

We can see that the configuration is divided into three sections. The <strong>[options]</strong> section, <strong>[openSSH]</strong> section to open SSH port and <strong>[closeSSH]</strong> section to close SSH port.</div>

As we know before, knockd will open particular port temporarily. So we have to make sure firewall is running on the server. Basically, we will close all ports. We are using iptables syntax to do it. Here are the steps.</div>

<br />
The 1st command, will allow the current on-going session through firewall.<br />
The 2nd command, will allow the server is able to ping by another machine.<br />
The 3rd command, will reject every requests.</div>
<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
To test the knockd service, we expect that our will firewall will drop all ssh connection. Then knockd will open it temporarily on demand.</div>

Once the firewall and knockd are setup, next we can test them.<br />
To test the firewall, try remote the server via SSH from another machine. (<em>on this article, client IP is 10.1.6.14 and server IP 10.0.76.224</em>)</div>

<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
If the firewall works, then we will get <strong>“Connection refused”</strong> error message.</div>

<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">

<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
To run knockd, we need to change knockd default file which located in /etc/default/knockd. Change the value of <strong>START_KNOCKD parameter from 0 to 1</strong>.</div>

On the client side, we need knock client to “knock” the server. On the client side, we use Centos 5.2. Then we install knock-client from <a href="http://pkgs.repoforge.org/knock/knock-0.5.3.el5.rf.i386.rpm" style="outline: none; text-decoration: none;" title="knock client">http://pkgs.repoforge.org/knock/knock-0.5.3.el5.rf.i386.rpm</a></div>

On the previous one, after knock to open the port, we saw that the client IP Address - 10.1.6.14 - is allowed to enter the server by firewall. Now, after we knock to close the port, if we check with the same iptables command, the rule was deleted.</div>

Since the close port activity is triggered by client, we will have the possibility that the client forget to close the port. We don’t want it to happen. So we can configure knockd to close the port automatically.</div>
<div style="background-color: white; font-family: Arial, Helvetica, sans-serif; font-size: 14px; line-height: 21px; margin-bottom: 15px; word-break: break-word;">
