			<content:encoded><![CDATA[<p>I experienced a problem whilst setting up PPTP VPN server on a Ubuntu install using webmin.<br />
I can establish a VPN connection into my Ubuntu server and access resources on that server, but i can&#8217;t access the LAN or WAN (ie other computers on network or internet).</p>
<p>I think the problem is the Netmask. In Webmin, under routing and gateways, the netmask for my ppp0 interface is different than for the rest of the network. (255.255.255.255 instead of 255.255.255.0)</p>
<p>The problem can be solved by using the following commands</p>
<p>cat /proc/sys/net/ipv4/ip_forward</p>
<p>Does it return 0 or 1?<br />
If it is returning 0, then do echo 1 > /proc/sys/net/ipv4/ip_forward and see what it does.</p>
<p>To make it permanent edit<br />
/etc/sysctl.conf and uncomment the line: net.ipv4.ip_forward=1</p>

			<content:encoded><![CDATA[<p><strong>Module mod_rewrite URL Rewriting Engine</strong></p>
<p>Most dynamic website pages built on windows platform will have a .asp or .aspx extension.</p>
<p>If your converting a site from windows platform to php and intend on hosting the new site on an apache server then you will probably want to honour the .asp or .aspx pages that have already been  indexed within the search engines.</p>
<p>To do this you will need to use apaches rewrite engine.<br />
This module provides a rule-based rewriting engine to rewrite requested URLs on the fly.<br />
This means that when a website visitor requests a .asp page then you can rewrite the url and redirect them to the equivalent .php page.</p>
<p>To do this create a .htaccess file and place it in the root folder of your website OR the folder which contains the old .asp pages you wish to redirect.</p>
<p>This example shows redirection on the site www.bizante.com but you can change bizante.com to your own website.</p>
<p>RewriteEngine on<br />
rewritecond %{http_host} ^bizante.com [nc]<br />
rewriterule ^(.*)$ http://www.bizante.com/$1 [r=301,nc]<br />
RedirectMatch 301 (.*)\.asp$ http://www.bizante.com$1.php</p>
<p>Here is a link to the official Module mod_rewrite page for Apache HTTP Server Version 1.3</p>

			<content:encoded><![CDATA[<p>To avoid a disaster and/or data loss during a power cut it is necessary to use an uninterruptible power supply (UPS).</p>
<p>A UPS is basically a battery which holds a charge big enough to power your computer system in the event of power loss as a result of a power cut.</p>
<p>UPS&#8217;s come in various sizes. The bigger the higher the cost. To keep the cost down you can use a UPS which provides enough power to shutdown your computer system safely as soon as it experiences a power outage.</p>
<p>Most UPS will send a signal to your PC to let it know that the mains power has gone. The PC will then shutdown safely and you can start using again when the power comes back.</p>
<p>Most UPS also safeguards your equipment from damaging electrical surges and spikes that travel along your utility and phone lines. </p>
<p>One of the more well known UPS manufacturers is APC. Visit there website <a href="http://www.apc.com" target="_blank">here</a></p>
<p>Here are links to a couple of online retailers which sell UPS at a reasonable price.<br />

			<content:encoded><![CDATA[<p>MixMeister BPM Analyzer is a free program you can use to determine the exact BPM (beats per minute) of any song without DRM.</p>
<p>MixMeister is available for free to download from<br />
<a href="http://www.mixmeister.com" target="_blank">http://www.mixmeister.com</a></p>
<li>Calculate extremely accurate BPM counts for any song</li>
<li>Drag and drop music files from Windows Explorer</li>
<li>Display and sort files by Title, Artist, or BPM</li>
<li>Update ID3 tags in your music files with exact BPM information</li>
<li>Easily print BPM reports for your entire music collection</li>
<li>Export BPM counts for use in other programs</li>
<li>Free to use and distribute for non-commercial purposes</li>
<p>To find the bpm of a song from within iTunes simply command click (right click) on the tune and select SHOW IN FINDER.</p>
<p>This will open up a finder window.<br />
From here you can drag and drop the tune directly into the MixMeister window.<br />
The bpm will be stored in the ID3 tag of your tune.</p>
<p>NOTE: This can only be done with tunes that are not DRM protected.</p>
<p>HOW TO REMOVE DRM from iTunes purchases.</p>
<p>When you have bought music from the iTunes Store in the past the files will probably be copy protected by Apple&#8217;s FairPlay DRM system.<br />
This system was put in place to protects the rights of the artist and publisher by making it difficult for the consumer to distribute copyrighted material. Fair enough? Unfortunately this system prevents you from playing your DRM&#8217;ed music on a non-iPod.</p>
<p>Apple now offers DRM-free tracks but for those of you with tunes that are still protected you can remove the DRM by burning the tunes to CD from iTunes and then re-importing the CD.</p>

			<content:encoded><![CDATA[<p>Now Im a big fan of Skype but recently I have found that there is a distinct lack of information which helps people understand exactly what they are going to be charged for when making or receiving calls using skype from a mobile device.</p>
<p>Here is a quick run down on the various versions of skype compatible applications and an explanation of exactly how they go about making  calls.</p>
<p>For the purpose of this explanation Im going to exclude the use of WIFI as a carrier simply because Im trying to understand whether making or receiving a Skype call on my mobile without WIFI is going to cost me.</p>
<p>Also for the purpose of this explanation the word free, only means free if its being referred to as part of your inclusive voice and data allowance available on your mobile&#8217;s contract. For example my current contract might give me 500 minutes a month and 1GB of data. So according to the Telecoms industry this is referred to as free. In my case I have to pay £30 a month for the 500 free minutes and 1GB of free data. The Telecoms industry have abused the english language to suit their advertising speak so I guess will have to get used to it.</p>
<p><strong>(scenario 1)</strong> Make and receive free skype to skype calls<br />
The only way of making and receiving free skype calls at the moment is to use a mobile with skype built in such as the <a href="http://www.three.co.uk/Mobiles/3_Skypephone" target="_blank">3 Skypephone S2</a><br />
This solution transmits the calls voice over the ip network and is therefore a true VOIP solution. In my opinion this should be the only scenario available. The alternative way of achieving this scenario is to use the skype client called Fring available <a href="http://www.fring.com">here</a><br />
Fring allows you to make and receive calls over your internet data plan. Fring also allow you to sign into numerous social networks simultaneously such as  MSN Messenger, ICQ, Google Talk, Twitter, AIM and Yahoo! buddies. The only downside is that for some reason the call quality is not as good as using the skype client. Im not sure why this is but think its probably because the call is being redirected through another server.</p>
<p><strong>(scenario 2)</strong> Make free skype calls and pay for receiving skype calls<br />
This solution allows you to make free outgoing skype calls because the mobile devices skype client dials a normal landline. Your Skype call is therefore carried through the normal channels just as a voice call probably to a datacentre where it is then channelled down the internet to its destination.<br />
If you have free minutes as part of your mobile contract then this call well be free. You skype client will also use a small amount of data to let the server know you are online and whether your about to make a call.</p>
<p><strong>(scenario 3)</strong> Pay for making and receiving skype calls. This is where you use skype without having any call plan which gives you free minutes. There is no benefit to using your mobile as a device to make skype calls in this way except that you can contact other skype users which you would not be able to do without using a skype client.</p>
<p>The big issue with being able to make and receive free calls using skype is whether or not you can make the calls and receive the calls over your mobile devices data network.</p>
<p>Most devices are capable of making and receiving calls using the data network but, a lot of devices are disabled for many different reasons.<br />
The main reason that mobile devices have restrictions put on them is that if you can make a free call then your not going to need to pay for it, which means the companies are not going to make so much money.</p>
<p>There are various ways to re-enable mobile devices to make and receive calls using the data network.</p>
<p><strong>IPHONE &#038; SKYPE</strong></p>
<p>For those iPhone 3GS owners you can purchase a 3G unrestrictor app to allow Skype to work over the 3G data network. This works by tricking applications into believing they are on WiFi, even though they are on 3G or EDGE.</p>
<p>If your an iPhone 3G owner then you can jailbreak your iphone and install VoIPOver3G via Cydia, and it will automatically hack Skype to work over 3G data network.</p>
<p>If you live in the United States your onto a real winner because you can subscribe to an unlimited Skype calling plan for $3 a month and make unlimited calls. In the United Kingdom you can get a similar calling plans for landlines but beware of the Skype to mobile rates. They are whats commonly known within the consumer market as a &#8220;RIP OFF!&#8221;<br />
At the time of writing this I think its about 0.16 GBP to call a United Kingdom mobile from Skype. This is also the price you yourself will pay for receiving a Skype call on your Mobile unless your setup like (scenario 1) described above. </p>
<p><strong>A note on Jail-breaking your phone.</strong></p>
<p><strong>If you jailbreak your iphone you will invalidate your warranty and the EULA which you signed when you purchased your iphone.</strong></p>
<p>Jail-breaking your iPhone is the term which refers to disabling the restriction which prevents you from installing un-licensed application on your iPhone. There are several strong underground scenes which develop and promote application for the iPhone. A lot of these underground apps cannot be found on the iTunes App Store. To date the easiest way of Jail-breaking your iphone is through this website <a href="http://blackra1n.com/">http://blackra1n.com></a></p>
