<p>I think next time I&#8217;ll try the plane which also departs from Merzbrück and explicitly mentions Aachen proper as one point of its route.</p>

			<content:encoded><![CDATA[<p>Here we go again. With nothing more substantial to blog, I&#8217;ll just give you the quick rundown of some of my favorite shots of 2011, at least in terms of photographic technique. Needless to say, only a fraction of my photos make it to flickr each year. I&#8217;ll try to sort the shots by theme this time ;) Everything I posted on flickr this can be found here: <a href="http://www.flickr.com/photos/heipei/archives/date-taken/2011/detail/">http://www.flickr.com/photos/heipei/archives/date-taken/2011/detail/</a></p>
<h3>People</h3>
<p>Actually, most of the shots are of Katrin since she has the patience for me to try all kinds of silly new techniques ;). I&#8217;m not the best photographer for people, but I hope to improve with the fast ISO of my new EOS 60D.</p>

<h3>Landscapes</h3>
<p>Now, landscapes is what I really like to photograph. Not because it&#8217;s easier than people which move around, but because capturing the impression of a clear blue sky above miles of open view is quite a challenge. Looking back at my photos of this year, I like the obvious progression of the seasons.</p>

<h3>Cities</h3>
<p>Similar to landscapes, but more variety on a small room. In cities I often feel like getting an imperfect shot because of wires running through the image, but that&#8217;s just me, and in the end some of my best shots of 2011 were from Berlin and Potsdam. Not surprisingly, I used my Polfilter on my 18-200 mm EF-S all the time, with varying but mostly great results.</p>

<h3>Stock / Studio / Miscellaneous</h3>
<p>I don&#8217;t &#8220;do&#8221; stock photography, but some of my images can be (and have been) used that way. Food could be a whole category by itself, but I&#8217;ll just group it here as well. Everything food-related can of course be found on <a href="http://www.morenz.de/">Katrins Blog</a>.</p>

			<content:encoded><![CDATA[<p class="hyphenate">To commemorate the end of my studies (Computer Science) I got myself a new toy. This time I opted for something substantial instead of many small and sometimes pointless gadgets which will only accumulate dust after their initial use. So, after careful consideration and a long period of reflection, I got myself a racing bike. This is what it looks like:<img src="/weblog/vortrieb_2011_rr.jpg" alt="Vortrieb 2011 Road Race" class="aligncenter"/>Although there are many large bike stores here in Aachen with a large selection of bikes, I chose a small store in downtown Aachen called <a href="http://www.vortrieb.com">Vortrieb</a> which has a large online presence for bike parts and a small store selling preconfigured bikes. Since you don&#8217;t just need a bike I went ahead and added stuff like cycling shoes, pedals, clear glasses, a helmet, a shirt, a bottle and cushioned shorts. Using shoes with a click system requires some training (I&#8217;m using SPD-SL Shimano cleats) but I was able to get up to speed without toppling over once.</p>
<p class="hyphenate">As I said I was pretty sure that a racing bike would be good investment beforehand, judging from the amount of cycling I did with my old mountainbike. Aachen and its surroundings are perfect for cycling: Lots of cute small villages connected by many small farm roads, an interesting landscape and three countries to explore. Driving east the landscape gets flat very soon, but to the west and south of the city, a mixture of farmland, forest and villages is distributed on gently sloping hills and in small valleys. After having familiarized myself with the bike in the last two weeks I decided to put it (and myself) to the test on some unknown terrain.<br />
You can view my route below, click for <a href="http://maps.google.com/maps/ms?ie=UTF&#038;msa=0&#038;msid=212517608340071339952.0004a4cbb7c3e3d4d053a">Google Maps</a>, <a href="/weblog/track_2011_06_02.gpx">downloadable GPX</a>. Distance was about 47km, combined elevation about 850m, it took me two and a half hours. I visited villages like Lemiers, Holset, Mechelen, Epen, Sippenaeken, Plombieres, Moresnet and Vaals.<br />
<a href="http://maps.google.com/maps/ms?ie=UTF&#038;msa=0&#038;msid=212517608340071339952.0004a4cbb7c3e3d4d053a"><img src="/weblog/track_2011_06_02.png" alt="Route 2011-06-02" class="aligncenter"/></a>Me cycling without a tachometer means that I have a new use for my Garmin etrex H GPS. I had to <a href="http://www.jens-seiler.de/etrex/datacable.html">build a connector cable</a> though since I didn&#8217;t want to buy the totally overpriced serial cable from Garmin.<br />
<img src="/weblog/track_2011_06_02_elevation.png" alt="Elevation" class="aligncenter"/>I hope to do more posts like this in the future, the amount of work transferring the GPX is negligible and I have a feeling that a lot of people are interested in GPS routes.</p>

			<content:encoded><![CDATA[<p class="hyphenate">My last post was about the photographic year 2010 and this is barely any different. I hope to blog about something substantial very soon, seeing as I&#8217;m done with my Diploma Thesis now, but in the meantime enjoy the photos and the comments.

<p>I completed my first long hike this year in February. It was part of our the vacation program of our fraternity to bridge the gap between the lecture periods of the winter- and summersemester. You can read about it <a href="http://www.alania-breslau.de/content/view/220/1/">here</a> (in German) and also view the <a href="http://photos.heipei.net/2011/2011-02-20%20Wanderung%20Preuswald/index.html">whole gallery</a> on my photosite. Interesting hiking trails in and around Aachen can be found with <a href="http://www.grenzrouten.eu/">the Grenzrouten</a>, printable PDFs included.</p>

<p class="hyphenate">It&#8217;s probably safe to say that most of the time the shutter on my trusty EOS 400D was released, something delicious was right in front of it. Yes, this year has been ripe with a lot of delicious meals and the accompanying recipes, thanks to Katrin. She recently introduced her recipes in the PDF format on <a href="http://www.morenz.de">her foodblog</a>, so there is no excuse not to try any of them. Head on over to <a href="http://www.morenz.de">her foodblog</a> and leave comments, if you haven&#8217;t already subscribed to it via RSS. As far as photography goes, most of the shots for her blog are pretty much the same setup: TTL-flash, on camera, towards ceiling, dialed up to correct for the white plate, 1/200s exposure, 50mm 1.4 @ 4.0 or something like that. Most of the time the timeframe to take the shot is limited to about 60 seconds, a bloggers gotta eat too. I did try some new tricks though: Used my second flash and part of the Hama mini photostudio to light the food from behind and front. Center image below. An even simpler trick I recently started using when trying to add some depth to the shot is to point the camera straight downward and the flash towards a (white) wall at a right angle. This should give more defined shadows than using the ceiling, as can be seen in the other two shots.<br />
<a href="http://www.flickr.com/photos/diekatrin/5558614308/" title="How to make a bagel... by diekatrin, on Flickr"><img src="http://farm6.static.flickr.com/5307/5558614308_ff6f9c5b87_m.jpg" width="240" height="160" alt="How to make a bagel..."/ style="vertical-align:middle"/></a><a href="http://www.flickr.com/photos/heipei/5368316880/" title="My contribution to dinner by heipei, on Flickr"><img src="http://farm6.static.flickr.com/5044/5368316880_c0e803e754_m.jpg" width="160" height="240" alt="My contribution to dinner"/ style="vertical-align:middle"/></a><a href="http://www.flickr.com/photos/diekatrin/5643836292/" title="Eier-Gurken-Sandwiches mit Senfcreme by diekatrin, on Flickr"><img src="http://farm6.static.flickr.com/5002/5643836292_b77319d6e8_m.jpg" width="240" height="160" alt="Eier-Gurken-Sandwiches mit Senfcreme"/ style="vertical-align:middle"/></a></p>
<p class="hyphenate">Then there were the usual amount of parties and social events, only a fraction of those made it into my flickr account. One noteworthy day was the first of May, were we traditionally hike to our tree behind the Aachen golf club. The weather on that event was stunning, and the photos reflect that fact. Katrins headshot was an attempt to produce a photo suitable for a job application. I know that the green background might be distracting, but I think it&#8217;s pretty nevertheless. Interestingly enough, this photo was shot inside our living room, in front of the open balcony door, using both my flashes to correctly balance subject and background. I think it came out great, but then again, I tend to favor overly colorful and bright shots ;)</p>

			<content:encoded><![CDATA[<p><a href="http://www.exzellenz.rwth-aachen.de/aw/cms/home/Zielgruppen/zukunftskonzept/massnahme/projekt_urop/~srg/rwth_urop/?lang=de"><img src="http://media.heipei.net/urop.jpg" alt="UROP" class="alignleft" style="border: 0px"/></a>Heute haben <a href="http://www.hackvalue.de">Flo</a> und ich unser UROP-Projekt erfolgreich beendet. Da ich, von allen Leuten mit denen ich in den letzten paar Monaten gesprochen habe, niemanden gefunden hab der überhaupt von UROP gehört hatte werde ich versuchen diese Lücke mit einem Blogpost ein wenig zu schließen. Die Details unseres Projekts werde ich ggf. in einem späteren Post erläutern.</p>
<p><b>Was ist UROP?</b><br />
<img src="http://media.heipei.net/urop_mgmt.jpg" alt="UROP" class="alignright"/>UROP, das Undergraduate Research Opportunities Program, ist ein Förderungsprogramm für Studenten. Wie der Name verrät richtet es sich an Undergraduates, also auf das neue BA/MA-System bezogen auf Bachelor-Studenten. Das Research im Titel bezieht sich darauf dass einzelne Forschungsprojekte gefördert werden sollen. Es ist kein Research-Grant in dem Sinne wie man es vielleicht kennt: Mittel für ein Projekt beantragen und dann loslegen. UROP fördert Projekte nach ihrem Abschluss (wenn sie denn erfolgreich beendet wurden) und nach einer Evaluation der fertigen Arbeiten. Das bedeutet allerdings auch nicht dass man sich die Förderung wie ein Wettbewerb vorstellen soll bei dem die besten N Beiträge ausgezeichnet werden.</p>
<p><img src="http://media.heipei.net/urop_researcher.jpg" alt="UROP" class="alignleft"/><b>Ablauf</b><br />
Wenn man ein Projekt gefunden hat und angenommen wurde kann man loslegen. Ob allein oder im Team ist prinzipiell egal. Zuerst muss man ein paar formale Dinge erledigen: Anschreiben, Lebenslauf, Motivationsbrief. Der Projektzeitraum ist sehr flexibel (ob ein ganzes Jahr oder nur ein paar Wochen), allerdings gibt es nur halbjährlich die Möglichkeit eine Förderung zu beantragen. Man hat einen Betreuer am Lehrstuhl mit dem man regelmäßig den weiteren Verlauf abspricht. Hat man das Projekt beendet schreibt man noch einen dreiseitigen Abschlussbericht und hält eine kurze Präsentation im Zuge des halbjährlichen UROP-Kolloquiums. Vom Betreuer (bzw. Prof. am Lehrstuhl) wird dann auch noch eine Evaluation geschrieben die direkt an UROP geht. Noch ein bisschen Papierkram und man ist fertig. Zuletzt wird das Projekt bewertet (von anderen Profs im eigenen Fachbereich) und wenn alles stimmt erhält man die Förderung (max. 2000€ pro Projekt).</p>
<p><b>Warum sollte man an UROP teilnehmen?</b><br />
Das ist eine gültige Frage, kriegt man doch selbst in den einfachen HiWi-Jobs mit 8h/Woche immerhin mehr Geld, rein auf die Arbeitszeit bezogen (hey, das ist nicht meine Argumentationsweise aber solche Sachen wurde ich teilweise gefragt). Allerdings arbeitet man dabei nicht unbedingt so flexibel (was die Zeiteinteilung angeht) und zielorientiert. Wenn man nicht grade an einem guten Lehrstuhl eine Stelle bekommen hat fehlt evtl. sogar der wissenschaftliche Aspekt der Arbeit gänzlich. Die Menge der Leute die sich über das Studium beschweren weil man, selbst in Seminararbeiten oder Praktika, nur bereits Bekanntes zusammenfasst ist groß genug, so dass ich da ein gewisses Interesse vermute. Über ein UROP-Projekt kann man gut mit Mitarbeitern am Lehrstuhl in Kontakt kommen, nicht unwichtig für die spätere Wahl bei der Diplom/Master-Arbeit oder sogar bei weiterführenden Plänen (zugegebenermaßen kann man solche Kontakte natürlich auch unabhängig aufbauen, so gern sich auch alle Veranstaltungen rund um die Uni &#8220;Networking&#8221; auf die Fahne schreiben). Darüberhinaus schadet es sicherlich nicht ein abgeschlossenes UROP-Projekt auf dem Lebenslauf zu haben.</p>
<p><img src="http://media.heipei.net/urop_people.jpg" alt="UROP Kolloquium" class="aligncenter"/></p>
<p><b>Warum mache ich Werbung dafür?</b><br />
Wie gesagt, ich find es schade dass so wenig Leute überhaupt von UROP mitgekriegt haben. Die Fördertöpfe (übrigens im Rahmen der Exzellenzinitiative geschaffen, für alle die meinen dass Studiengebühren auf keinen Fall wieder zu den Studenten zurückfinden) sind voll und es gab bei den letzten vier UROP-Runden weniger Bewerber als Stipendien. Was das Kolloquium angeht waren die Vorträge der anderen UROP-Projekte sehr interessant. So haben wir erfahren dass manche Insekten zwar an Scheiben kleben können, um den Gefrierpunkt aber plötzlich ihre Haftfähigkeit verlieren (das ist mal über den Tellerrand geschaut für Informatiker! ;) Inzwischen gibt es sogar UROP Abroad, ein Programm mit dem man ein UROP-Projekt in den USA/Kanada verfolgen kann. Das hat bisher nur eine Person gemacht, aber die war immerhin im schönen Saskatchewan.</p>
<p><b>Wo kann man sich informieren?</b><br />
Am besten auf der <a href="http://www.exzellenz.rwth-aachen.de/aw/cms/home/Zielgruppen/zukunftskonzept/massnahme/projekt_urop/~srg/rwth_urop/?lang=de">RWTH UROP Seite</a>. Dort ist auch die <a href="http://www.zhv.rwth-aachen.de/mainzhv.php?scriptid=iou&#038;param=sucheprof&#038;lang=en&#038;liste=1">Projektdatenbank verlinkt</a>. Allerdings sollte man sich davon nicht abschrecken lassen. Am besten ist man spricht mit einem Assistenten oder Prof ob er nicht ein Projekt hat was gut in den Rahmen von UROP passen würde.</p>

			<content:encoded><![CDATA[<p><a href="http://heipei.net/studium"><img src="http://media.heipei.net/seminare_protokolle.jpg" alt="Seminare" class="alignleft"/></a>Nach einer Menge Posts über anderen Kram und neidischen Blicken zu <a href="http://hackvalue.de/hv_studium">Flos aufgeräumter Studiumsseite</a> wollte ich mal noch ein paar Dokumente aus den letzten Semestern aus dem Schrank holen. Vielleicht hilft es ja dem ein oder anderen Studieninteressenten der sich nicht vorstellen kann was man überhaupt so während seines Informatikstudiums macht.</p>
<p><b>Seminare</b><br />
Seminare bei uns in der Informatik funktionieren wie folgt: Man bewirbt sich auf ein Seminar zu einem groben Überthema bei einem der Informatik-Lehrstühle. Wenn man Glück hat kriegt man den Platz seiner ersten Wahl. Vor dem Semester sucht man sich dann eins der Themen aus und kriegt ein oder mehrere Paper auf denen man aufbauend seine Seminarausarbeitung schreiben soll. An der Stelle merkt man schon dass der Anteil origineller Arbeit beschränkt ist, was durchaus so vorgesehen ist. Ziel eines Seminars ist es schliesslich sich selbstständig in ein Thema einzuarbeiten und das Ganze dann in einen wissenschaftlich aussehenden Artikel zu gießen. Dafür hat man ein paar Monate Zeit, am Ende gibt es dann ein paar Tage lang Vorträge an denen man sein Seminar den anderen Teilnehmern vorstellt. Ich habe im Hauptstudium zwei Seminare gemacht (und ein Praktikum):</p>
<ul>
<li><b>Praktische Informatik</b>: <em>The most efficient SHA-1 attacks</em> (Prof. Meyer) &#8211; <a href="http://heipei.net/studium/seminar_praxis.pdf">Ausarbeitung</a> und <a href="http://heipei.net/studium/slides_praxis.pdf">Slides</a></li>
<li><b>Theoretische Informatik</b>: <em>Das Cross-Section-Theorem und nicht-mehrdeutige Transducer</em> (Prof. Thomas) &#8211; <a href="http://heipei.net/studium/seminar_theorie.pdf">Ausarbeitung</a> und <a href="http://heipei.net/studium/slides_theorie.pdf">Slides</a></li>
</ul>
<p><b>Prüfungsprotokolle</b><br />
Bei uns im Hauptstudium schreibt man keine Klausuren mehr (abgesehen von ein paar Scheinklausuren) sondern hat mündliche Prüfungen. Manche Leute schreiben Gedächtnisprotokolle einer Prüfung, damit sich andere besser auf die Atmosphäre bei solchen Prüfungen und den Tiefgang vorbereiten können, den eigentlichen Stoff der abgefragt wird sollte man ohnehin komplett drauf haben ;)</p>
<ul>
<li><b>Protokoll Theoretische Informatik</b>: <em>Angewandte Automatentheorie, Unendliche Spiele, Automaten auf unendlichen Wörtern, Cryptography I + II</em> (Prof. Thomas, Prof. Mathar) &#8211; <a href="http://heipei.net/studium/protokoll_theorie.pdf">Protokoll</a></li>
<li><b>Protokoll Praktische Informatik</b>: <em>Datenbanken, Logic of Knowledge Bases, Logikprogrammierung</em> (Prof. Lakemeyer) &#8211; <a href="http://heipei.net/studium/protokoll_praxis.pdf">Protokoll</a></li>
<li><b>Protokoll Vertiefung</b>: <em>IT Security I + II, Massively Distributed Systems I, Communication Systems Engineering I</em> (Prof. Wehrle, Prof. Meyer) &#8211; <a href="http://heipei.net/studium/protokoll_vertiefung.pdf">Protokoll</a></li>
</ul>
<p><b>UROP</b><br />
Zusätzlich haben Flo und ich noch an UROP teilgenommen, dem Undergraduate Research Opportunities Programme der RWTH. Für UROP werden Projekte in unterschiedlichen Fachbereichen ausgeschrieben auf die man sich bewerben kann um dann schon während des Studiums erste Schritte im wissenschaftlichen Arbeiten zu machen. Unser Projekt, welches wir am LuFG Informatik 4 &#8211; Distributed Systems Group (Prof. Wehrle) durchgeführt haben hieß <em>ALPHA &#8211; An Adaptive and Lightweight Protocol for Hop-by-Hop Authentication</em>. Dabei ging es darum ein Protokoll zu implementieren (und zu erweitern), mithilfe dessen Netzwerkpakete an jeder Stelle im Netzwerk auf Integrität geprüft und ggf. direkt verworfen werden können, z.B. um mobile Endgeräte vor falschem Netzverkehr zu schützen der sonst die Resourcen (CPU und damit auch Batterie) dieser Geräte beanspruchen würde. Zu UROP werde ich bald noch einen eigenen Artikel schreiben. Für UROP mussten wir eine kurze Ausarbeitung schreiben, mit ein bisschen Hintergrundwissen sollte man das Prinzip von ALPHA verstehen.</p>
<ul>
<li><b>Implementation and Improvement of ALPHA</b>: <a href="http://heipei.net/studium/article_alpha.pdf">Ausarbeitung</a> für UROP und <a href="http://heipei.net/studium/slides_alpha.pdf">Slides</a> des UROP Kolloquiums</li>
<li><b>ALPHA  &#8211; An Adaptive and Lightweight Protocol for Hop-by-Hop Authentication</b>: Das <a href="http://ds.informatik.rwth-aachen.de/members/heer/publications-tobias-heer/pdfs/alpha-an-adaptive-and-lightweight-protocol-for-hop-by-hop-authentication.pdf">Original-Paper</a> auf dem das Protokoll aufbaut</li>

First and foremost I got a new lens for my birthday. The Canon EF-S 18-200mm 3.5-5.6 IS. This was meant as a replacement for the rather basic 18-55mm that came with my 400D body. So far the 18-200 hasn&#8217;t disappointed me. I&#8217;m really using the big span of the focal length and since it is meant as my alround-lens I didn&#8217;t care to much about the 3.5 open aperture (I&#8217;ll mostly use it for trips or well-lit situations, my EF 50mm 1.4USM is still the basement-party weapon). Check out a few of my photos on flickr to get an idea of the lens. The IS is really nice, the handling feels rich. The only downsides of this lens are it&#8217;s weight and the autofocus which sometimes has a hard time in low light conditions.</p>
<p>A few weeks ago I decided to finally buy a flash. I didn&#8217;t hesitate long and bought the Canon 430EX II. Before that (and while waiting for DHL) I read a lot of <a href="http://www.strobist.blogspot.com/">strobist.com</a>, so that I hit the ground running when the flash did arrive. The nice thing about buying flashes is that you don&#8217;t have to worry so much about capabilities/size, because you can buy a bigger one which can act as master at some point in the future should you feel the need to. Along with the flash I ordered some small utilities, like the Phottix Tetra radio-triggers for off-camera flash, the Roscoe Strobist Gel collection (gel from &#8220;gelatine&#8221;. It&#8217;s called &#8220;Effektfolien&#8221; in german) and a small diffuser (just for fun). The Phottix Tetra have been great as well, especially considering the price-tag of about 30€, which is next to nil compared to other wireless triggers which quickly add up to ten times that much. However the Phottix triggers don&#8217;t support TTL, which is a measuring-system so the camera knows how to adjust for the flash. Well, what better time to really get acquainted with the M mode ;)</p>
<p><a href="http://www.flickr.com/photos/heipei/4282057138/" title="Aachen Open 2010 by heipei, on Flickr"><img src="http://farm5.static.flickr.com/4034/4282057138_4d1d0e8c2f.jpg" width="500" height="334" alt="Aachen Open 2010" class="aligncenter"/></a><br />
Aachen Open 2010, which just ended today, was the only real event I looked forward to, photography-wise, and it turned out really nice. Not only was the event itself a smashing success (no other way to put it, the organisation was flawless, the attendance was record-breaking and the venue perfect for our needs), but also meant many diverse personalities to photograph. You can see my complete photos of the event here: <a href="http://photos.heipei.net/Aachen_Open_2010/">photos.heipei.net/Aachen_Open_2010/</a> and photos by other people will be collected here: <a href="http://cube.hackvalue.de/ao10/media-de">http://cube.hackvalue.de/ao10/media-de</a>.</p>
<p><a href="http://www.flickr.com/photos/heipei/4282192117/" title="Reflective Umbrella DIY by heipei, on Flickr"><img src="http://farm3.static.flickr.com/2793/4282192117_efb2300055.jpg" width="500" height="334" alt="Reflective Umbrella DIY" class="aligncenter"/></a><br />
Tonight I salvaged an old (and broken) Umbrella and simply covered the inside with white xerox paper. I sawed of the round part of the handle and now it fits into the grip of my tripod. The Phottix has a mount option for standard tripods. The <a href="http://www.flickr.com/photos/heipei/tags/umbrella/">results are amazing</a>, and as usual I now feel much better when I buy an umbrella (I&#8217;m not quite sure whether I want reflective or shoot-through or both ;)</p>

			<content:encoded><![CDATA[<p><a href="http://cube.hackvalue.de/ao10/"><img src="http://cube.hackvalue.de/ao10/banner.png" alt="Aachen Open 2010" class="aligncenter" style="border: 0px;"/></a><br />
This is just a reminder that <a href="http://cube.hackvalue.de/ao10/">Aachen Open</a>, a German speedcubing competition, will take place again next year. More precisely on <strong>January 16/17, 2010</strong>. What&#8217;s even better is the huge number of registered participants and the new venue for the competition. Since the last place became quite crowded (and began to smell after about 2 hours) the management secured a larger spot in RWTHs Computer-Science building (Aula II, Ahornstraße 55). The downside for visitors is the distance to downtown Aachen, but on the bright side we&#8217;ll be equipped with internet throughout the competition.</p>
<p>Rest assured, I&#8217;ll be there, but probably less cubing and more photographing. So be sure to come by, even if just to get a glimpse of hardcore-nerds in a different area than your own profession. In case you missed the last Aachen Open, be sure to check out <a href="http://cube.hackvalue.de/ao09/">last years website</a> for impressions.</p>

			<content:encoded><![CDATA[<p><img src="http://heipei.net/weblog/eduroam.gif" class="alignleft" alt="eduroam"/>Manchmal muss man, trotz eduroam, noch das alte Cisco-VPN benutzen um sich ins Uni-Netz einzuwählen. Z.B. wenn man von Zuhause auf Dinge wie Springerlink oder andere Online-Bibliotheken zugreifen will, oder um auf bestimmte Hosts per SSH zu kommen die (sinnvollerweise) von aussen nicht erreichbar sind.<br />
In Mac OS 10.6 Snow Leopard kann man Cisco-Verbindungen glücklicherweise direkt mit dem Betriebssystem machen und ist endlich frei von dem nervigen Cisco-Client. Allerdings hat das ganze noch einen kleinen Bug, nämlich dass man sein Passwort bei jedem Verbindungsversuch neu eingeben muss. Wie man das vermeidet steht hier: <a href="http://www.macosxhints.com/article.php?story=2009082703155512">10.6: Save Cisco IPSec password in the keychain</a></p>
