				<content:encoded><![CDATA[<p>In my previous post you can read all about setting up 2-factor authentication using OTP on a juniper SA 4500 by using Radiator. About a week ago I tried to use the same Radiator configuration to work with Check Point Endpoint Security VPN E75.30, and it worked straight away. I was rather surprised, because I&#8217;d expected it would need some special configuration settings within Check Point. The juniper SA 4500 for example needs custom radius rules to get it working. Check Point doesn&#8217;t. Maybe that&#8217;s why I couldn&#8217;t find much documentation on this subject.</p>

				<content:encoded><![CDATA[<p>The past two weeks I&#8217;ve been looking into getting a <a href='http://www.juniper.net/uk/en/products-services/security/sa-series/sa4500/'>juniper SA 4500</a> to work with <a href='http://www.open.com.au/radiator/'>Radiator</a> to do two-factor authentication by using One-Time Passwords (OTP). Basicly, after user authentication is done against a Directory Server (DS), I want Radiator to lookup the user&#8217;s mobile number in the DS, create an One-Time Password and SMS this password to the user&#8217;s mobile phone.</p>
<p>Although Radiator can handle OTP, the AuthOTP.pm module that comes with Radiator isn&#8217;t sufficient to work directly with the Juniper. This is why I had to make a few changes to the original AuthOTP.pm module. Download the patch <a href='two-factor/AuthOTP_pm-1_9.patch'>here</a>.</p>
<p>In the configuration file below, you see an example on how to use the module.</p>

<h2>Configure the Juniper SA 4500</h2>
<p>Configuring two-factor authentication on the Juniper is really easy. When creating an user realm, you can choose to use an additional authentication server. So I configured two authentication servers. The first one authenticates against the Directory Server. The second authentication server uses radius to authenticate against Radiator. It will prompt the user to enter the One-Time Password.</p>
<h3>Configure the additional Authentication Server</h3>
<p>Create a new authentication server that uses RADIUS. Most important here are the &#8216;Custom Radius Rules&#8217;.<br />

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/auth_server.jpg" title="" class="shutterset_singlepic31" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/31__450x_auth_server.jpg" alt="auth_server" title="auth_server" />
</a>
</p>
<h4>Custom Radius Rules</h4>
<p>The custom radius rules define how the Juniper talks with Radiator.</p>
<h5>Rule 1</h5>
<p>Here we define that the Juniper expects a challenge from Radiator and makes sure the user will be prompted with a page where he can enter the password that was send to the user&#8217;s mobile phone.<br />

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/radius_rule_1.jpg" title="" class="shutterset_singlepic32" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/32__450x_radius_rule_1.jpg" alt="radius_rule_1" title="radius_rule_1" />
</a>
</p>
<h5>Rule 2</h5>
<p>This rule defines what to do if the password entered by the user is rejected by Radiator. It will show the reason why the password was rejected.<br />

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/radius_rule_2.jpg" title="" class="shutterset_singlepic33" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/33__450x_radius_rule_2.jpg" alt="radius_rule_2" title="radius_rule_2" />
</a>
</p>
<h3>Configure an User-Realm</h3>
<p>The screen below shows how easy it is to create an user realm that uses an additional authentication server. Make sure the session is ended when authentication to the additional authentication server fails.<br />

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/user_realm.jpg" title="" class="shutterset_singlepic30" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/30__450x_user_realm.jpg" alt="user_realm" title="user_realm" />
</a>
</p>
<p>Well, I hope this document will save you some time and money in setting up two-factor authentication on the Juniper SA 4500. Enjoy <img src='http://www.van-sluis.nl/wp-includes/images/smilies/icon_wink.gif' alt=';-)' class='wp-smiley' /> </p>

				<content:encoded><![CDATA[<p>A couple of days ago I read an interesting article about <a href='http://www.jpegmini.com'>JPEGmini</a> on <a href='http://www.petapixel.com/2011/08/25/jpegmini-magically-makes-your-jpegs-up-to-5x-smaller/'>PetaPixel</a>. JPEGmini is a new image compression service that can magically reduce the file size of your JPEG photos by up to 5 times without any visible loss in quality. Today, before uploading a new photo to <a href='http://photo.van-sluis.nl'>my photoblog</a> I decided to give this new service a try.</p>
<p>After post-processing the image, I exported it into the highest quality JPEG format at a resolution of 1800&#215;1200 pixels. The image that came out was about 916kb. After uploading it to JPEGmini the size of this image was reduced to only 134kb. So, it has been reduced 6.8 times. And yes, without any visible loss in quality. Amazing huh? <img src='http://www.van-sluis.nl/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>

	<img class="ngg-singlepic ngg-right" src="http://www.van-sluis.nl/wp-content/gallery/cache/29__450x_jpegmini.jpg" alt="JPEGmini" title="JPEGmini" />
</a>

<p>The file size of the final image has always been something I took notice off, because the template I use on my photoblog requires much higher resolution images than most other templates do. Normaly I would try to keep the image size under 350kb in order to keep image loading quickly. But with use of JPEGmini it seems that I&#8217;m now able to deliver higher quality images that are loaded even faster. Cool! 8)</p>

				<content:encoded><![CDATA[<p>Twee weken geleden schreef ik <a href='http://www.van-sluis.nl/?p=235'>hier</a> over het vervangen van de multiriem van mijn Peugeot 307 SW 1.6. Ik was in de verwachting dat ik alle problemen had opgelost en weer zorgeloos flink wat kilometers kon rijden. Helaas was dit niet het geval. Telkens tijdens een koude start, kwam er kortstondig een zeer hard piepend geluid onder de moterkap vandaan. Mijn eerste ingeving was dat dit te wijten was aan een slippende multiriem. Wat valt hier aan te doen?</p>
<p>Op diverse internet fora wordt geschreven dat je WD 40 of zelfs kaarsvet kunt gebruiken om van het piepen af te komen. Dit leek mij een eenvoudige oplossing. Dus ik naar de Brezan en zo&#8217;n busje WD 40 gekocht en hier en daar wat op de poelies en snaar gespoten. Echter zonder resultaat.</p>
<p>Later heb ik hier een monteur naar laten kijken en zijn eerste vraag was: &#8220;Waarom heb je er WD 40 op gespoten?&#8221;. Volgens hem was dit niet zo&#8217;n slim idee. Als je wilt dat de multiriem een betere grip heeft op de poelies, dan kan je deze beter ontvetten. Je kan er remreiniger op spuiten. En dat deed hij. Nu maar wachten of het probleem opgelost is.</p>
<p>De volgende ochtend tijdens de koude start &#8211; jawel &#8211; wederom piepende geluiden die de buren wakker maken. Misschien was er niet voldoende ontvet? Dus ik bij de Halfords zelf een bus remreiniger gehaald om vervolgens de multiriem te demonteren en alle poelies eens goed te reinigen. Zelfs krukaspoelie er afgehaald en met behulp van een oude tandenborstel en remreiniger flinkt ontvet.</p>
<p>Helaas mocht dit niet baten. Wat zou het dan kunnen zijn? Verkeerde maat multiriem? De automatische spanner die niet voldoende aanspant? Na weer flink wat googlen kwam ik erachter dat de krukaspoelie van mijn auto bestaat uit twee delen: Een binnen- en buitenzijde met daar tussen een rubbere ring. Als de poelie kapot is, dan kunnen deze twee delen onafhankelijk van elkaar gaan bewegen en ontstaat er ook een piepend geluid. Om te controleren of de krukaspoelie kapot is, kun je heel eenvoudig met wat krijt streepjes zetten op de krukaspoelie. Vervolgens ga je een eindje rijden. Als daarna blijkt dat de streepjes geen rechte lijn meer vormen, is de krukaspoelie stuk.</p>

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/krukaspoelie_controleren.jpg" title="Vier krijt streepjes over de lengte van de poelie." class="shutterset_singlepic26" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/26__450x_krukaspoelie_controleren.jpg" alt="Krukaspoelie controleren" title="Krukaspoelie controleren" />
</a>

<p>Op de foto kun je zien hoe ik zorgvuldig de krijt lijntjes heb aangebracht. Dus ik de motor gestart en gewacht tot het piepende geluid niet meer hoorbaar was. Echter, ik zag niet direct een verschil. Je moet echt wel een stukje rijden om er zeker van te zijn dat deze kapot is. En ja hoor, dat was ie. Zie de foto hieronder. <img src='http://www.van-sluis.nl/wp-includes/images/smilies/icon_sad.gif' alt=':-(' class='wp-smiley' /> </p>

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/krukaspoelie_defect.jpg" title="De binnenzijde van de krukaspoelie is verschoven ten opzichte van de buitenzijde." class="shutterset_singlepic27" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/27__450x_krukaspoelie_defect.jpg" alt="Krukaspoelie blijkt defect" title="Krukaspoelie blijkt defect" />
</a>

<p>Vervolgens was de oplossing simpel. Oude krukaspoelie vervangen door een hagel nieuwe. Deze heb ik bij Imbema gehaald voor 65 euro.</p>

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/krukaspoelie_nieuw.jpg" title="" class="shutterset_singlepic28" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/28__450x_krukaspoelie_nieuw.jpg" alt="krukaspoelie_nieuw" title="krukaspoelie_nieuw" />
</a>

<p>Al met al zijn het een paar leerzame weken geweest. Eigenlijk is het ook wel logisch dat juist de krukaspoelie kapot is gegaan. Zeker als je bedenkt dat deze uit twee delen bestaat en dat deze krukaspoelie vier weken eerder door een monteur verkeerd om is teruggezet. Dan komen de krachten die er op spelen van de tegengestelde richting.</p>

				<content:encoded><![CDATA[<p>For some time now, I&#8217;ve been working on the <a href='http://www.pixelpost.org/'>Pixelpost</a> template which I&#8217;m using for my <a href='http://photo.van-sluis.nl'>own</a> photoblog. Although it&#8217;s basicly a Pixelpost template, it isn&#8217;t 100% compatible with Pixelpost. Without getting to technical, it has to do with the fact that pixelpost displays every image on a unique page, while the template on my photoblog updates the image without opening a new page. This makes it possible to use the really cool slide left/right transitions the <a href='http://dev.andreaseberhard.de/jquery/superbgimage/'>SuperBGImage</a> jquery addon provides. So, while this nasty hack is working fine for me, it isn&#8217;t something I would like to share with the community since it will limit the way Pixelpost is intended to work.</p>

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/superb-screenshot.jpg" title="Screenshot of the Superb template for Pixelpost." class="shutterset_singlepic25" >
	<img class="ngg-singlepic ngg-right" src="http://www.van-sluis.nl/wp-content/gallery/cache/25__450x337_superb-screenshot.jpg" alt="Superb template" title="Superb template" />
</a>

<p>However, leaving out the smooth transitions that the SuperBGImage jquery addon provides, it can still be used to scale fullscreen backgrounds. And this is exactly what the Superb template does. To see this template in action, try the demo at: <a href='http://photo.van-sluis.nl/demo/superb'>http://photo.van-sluis.nl/demo/superb</a>.</p>
<p>The Superb template will be available for download soon at the Pixelpost repository. I&#8217;m still waiting for approval.</p>
<p>Hope you&#8217;ll enjoy this one. If so, let me know! <img src='http://www.van-sluis.nl/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
<p><b>Update:</b> Superb template is now available for download at Pixelpost <a href='http://www.pixelpost.org/extend/templates/superb-template/'>here</a>.</p>

While writing the <b>Google Plus</b> button, I decided to also write one to display the updated <b>Tweet Button</b> from Twitter. The earlier addon <b>Twitter This</b> was a little outdated, so I deleted this one from the Pixelpost repository. To use this addon, just use one of the following tags in the image_template.html to make them show next to your photo.</p>
<ul>
<li>&lt;TWEET_BUTTON_VERTICAL&gt; &#8211; displays a vertical button.</li>
<li>&lt;TWEET_BUTTON_HORIZONTAL&gt; &#8211; displays a horizontal button.</li>
<li>&lt;TWEET_BUTTON_NOCOUNT&gt; &#8211; displays button without counter.</li>
</ul>
<p>To see this addon in action, take a look at <a href='http://www.eelzak.nl'>Eelzak.nl</a> or download it <a href='http://www.pixelpost.org/extend/addons/tweet-button-with-counter/'>here</a> from pixelpost.

				<content:encoded><![CDATA[<p>At first glance the Panasonic DMC-LX5 may look like another point-and-shoot camera, however this little fellow has a lot more to offer. One great thing about this camera is the wide-aperture lens. While being a zoom lens the maximum aperture starts at f/2.0. Fully zoomed in the maximum aperture will drop to f/3.3. These large apertures will not only help one while shooting pictures in lowlight situations, but also makes it possible to isolate a subject by making use of the so called &#8216;shallow depth of field&#8217;. For example take a look at the coneflower below.</p>

</a>

<p>This coneflower was shot with the Panasonic DMC-LX5 at f/2.0. See how the shallow depth of field singles out the flower while at the same time reducing the effect of distracting background clutter. Another great feature is it&#8217;s ability to take macro or close-up shots. More on this subject soon <img src='http://www.van-sluis.nl/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>

		<title>Multiriem vervangen Peugeot 307 SW 1.6</title>

				<content:encoded><![CDATA[<p>Een kleine twee weken na het laten vervangen van de distributieriem, waterpomp en multiriem ging mijn auto kapot. De multiriem die nog geen twee weken oud was lag aan flarden. Omdat ik de oude multiriem (die nog in redelijke staat was) had bewaard, besloot ik zelf te proberen deze te vervangen. Zoals je kunt zien op de foto hieronder zijn de poelies redelijk goed bereikbaar. Na veel googelen kwam ik erachter dat dit model beschikt over een &#8216;automatische spanrol&#8217; en dat je deze kunt bedienen met ringsleutel 15. Zet deze op de spanrol (3) en trek hem naar je toe. Vervolgens kun je de multiriem erom leggen en laat je de spanrol terug veren.</p>

<a href="http://www.van-sluis.nl/wp-content/gallery/miscellaneous/p1010447.jpg" title="Onder de moterkap" class="shutterset_singlepic22" >
	<img class="ngg-singlepic" src="http://www.van-sluis.nl/wp-content/gallery/cache/22__450x_p1010447.jpg" alt="Peugeot 307sw 1.6 16V" title="Peugeot 307sw 1.6 16V" />
</a>

<p>Helaas waren mijn problemen hiermee niet opgelost. Als je goed naar de foto kijkt zie je dat poelie nr. 4 enigsinds uitsteekt ten opzichte van de andere poelies. Poelie nr. 4 is de krukaspoelie. Na het tonen van deze foto op het forum <a href='http://www.problemcar.nl'>problemcar.nl</a> had men het vermoeden dat de krukaspoelie kapot was. Daarom besloot ik deze eraf te halen, om te kijken of ik kon zien wat de schade was. Deze poelie zit vast met 3 M8 boutjes. Met ringsleutel 13 kon ik deze boutjes los draaien en kwam de poulie geheel los. Toen bleek dat deze verkeerd om gemonteerd was. Kennelijk had de monteur nog niet genoeg koffie gedronken toen hij met mijn auto bezig was. Na het omdraaien en monteren van de krukaspoelie en het bevestigen van de multiriem deed mijn auto het weer.</p>

				<content:encoded><![CDATA[<p>Until a few months ago, one would need additional software to get Windows Explorer to display RAW images shot with a digital camera on a 64-bit windows system. For example Canon and other vendors don&#8217;t bother to provide one for systems like these. In order to preview RAW images in the Windows Explorer one would have to buy software like <a href='http://fastpictureviewer.com' target='_new'>FastPictureViewer</a>.</p>
<p>But now happily enough Microsoft has filled this gap and provided the &#8216;Microsoft Camera Codec Pack&#8217;. They have released both a 32 and 64-bit package. You can download and read more about it here: <a href='http://www.microsoft.com/download/en/details.aspx?id=26829' target='_new'>http://www.microsoft.com/download/en/details.aspx?id=26829</a>. </p>
<p>Great huh!? <img src='http://www.van-sluis.nl/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
