operations center! we got a power problem…

It’s raining since hours…and I mean raining…So it finally happened: A blackout.
If you take a look at the power uplink you can guess what’s wrong here 😉 – The connector was quite hot…and the water made the remainder….

After some minutes the blackout problem was solved and the work on…whatever we worked on could continue… B-)

call me! call us! if you like…

Like on other hacker conferences there’s a DECT network available all across the area so that you can call your friends for coordination or chitchat…To get access to the DECT network you just go to the POC (Phone Operations Center) and bring your home-DECT-handset with you

And this time the numbers assigned to the participants are also available from the “normal” telephone network.

So if you want to call me, just dial the following number: 0031-411629-704 It’s a normal telephone number in the netherlands so you wouldn’t be charged more than your normal fee.

providing network connections…

We have 8 machines in our village connected to our HP2524 network switch… – but after two days there are 14 cables plugged into the switch…these cables go to some other tents around us.

we proudly present: Food and a HP2524

It turned out that there where not enough uplink ports for everyone at the next so called “Datenklo”…

…everyone just puts it’s network cable into it…and once the hour a member of the technical staff connects the new cable to one of the switches inside the “Datenklo”…

the last phrack magazine issue…I got one

w00t! 😉 Okay okay… So finally there’s something to put into a picture frame and on the wall….

For those who don’t know what the phrack magazine is…just visit their website and start reading with the 1st Edition from November 17, 1985… You see: It’s a quite old magazine… – and this number 63 will be the last issue. Sad but true.

first article from the What The Hack

It took two days to get some time to post the first article… so take it as a statement directly from the Netherlands:

Since I just installed Windows Vista Beta 1 on my notebook I am not able to create some panoramic views (I shot severals so far…) so you probably will have to wait till I get my favourite panoramic-view-creation-app running…

want to meet at the What The Hack?

After some internal discussions a small delegation of VJs, some DJs, some computer hardcore nerds, some wireless experts, some Microsoft fanatics and some UNIX geeks will be sent to this years What The Hack conference/event…but what’s it anyway?

What The Hack is an outdoor hacker conference/event taking place on a large event-campground in the south of The Netherlands from 28 until 31 July 2005.”

I just organized a Mercedes Sprinter transporter and VW Passat to get all our stuff to the Netherlands and back. It’s planned to start early on the 28th of July.

We won’t come empty-handed! This is what we’ll probably bring:

  • Tables, banks, chairs
  • video projector and screen
  • probably lots of computers
  • networking equipment
    • probably one Cisco Catalyst 3500 (no, not for any Cisco-throwing contest!)
    • a Linksys WRT54G OpenWRT-enabled
  • some Sony DV-cameras
  • some microphones
  • a 12V-powered cooling box
  • a Cafetiere (to make espresso)
  • hopefully enough DECT-phones
  • at least a small PA (home hifi?)
  • a good attitude, (german) humor etc. 😉

Of course you can expect a number of articles on this website straight from the conference.

Anyway. If you want to contact or meet me at the What The Hack just write a comment or an eMail or use one of the DECT phone numbers at the conference:

“You can reach some of the FeM-team by calling our toll-free service number: FEM1 (3361) through FEM5 (3365). A DECT-phone is required (on your side), though.”

Or you just come to the FeM Village where I can be found when I am not in any talk.

Codetuning on a 32-way Itanium 2 SGI Altix machine

So this morning we played with these nifty dual Itanium 2 HP Servers…and now this: After a short talk with Intel my colleague Matej got access to an SGI Altix 3000 Supercomputer.

they look like that… nice ain’t it?

And because we’re just playing with that machine and there’s no benchmarking or anything like that done until now here are some “juicy facts” straigt from bash:

and the CPU Info of one CPU…:

does anyone know why the BogoMIPS are that low?

TechEd Europe 2005: Holistic Security

As I am a true fan of the sessions of Rafal Lukawiecki. And the fact that he is talking about really interesting subjects leads me directly to his todays session “Holistic Security”.

“You know all the security technologies, but are you secure? How much should security cost? The tough realities of today make security of enterprise systems one of the highest priorities on most IT Professionals’ agenda. This conceptual, rather than technical, session will overview security from a holistic, process-oriented perspective. While still uncommon, this approach seems to best model the threats that affect our installations. This way of looking at security is based on risk assessment and worries about all aspects of the system equally: we do not want to be building bullet-proof steel doors in a house made of paper walls. After discussing the main challenges that make achieving optimal security difficult, we will concentrate on three process-based holistic approaches: OCTAVE, Simplified Security Risk Analysis, and Threat Modelling.”

This panoramic view is in my opinion by far the best I’ve made this week. Enjoy.

why the Golden Tulip in Amsterdam rocks

After the smooth and on-time arrival at Amsterdam Airport Schiphol. After meeting with Matej we checked in at our hotel “Golden Tulip Inntel” and guess what: They have free wireless Internet Access in the Hotel … just everywhere. Finest 54Mbit … and it’s 54 Mbit… whoooo!

Actually what alarms me is the fact that there’s simply no security at all. You just connect to the WLAN and you have Internet Access. Nothings filtered. Just working Internet as is should be… I asked the reception if they aren’t concerned about the fact that somebody could possibly do some … well … illegal things from their WLAN… I think they did not understand what I meant… so I just yelled “Hack the planet” and went to my room… 😉

Forza Motorsport Multi-Screen Experience

So finally there is a multi-screen mode in Forza Motorsport. For each display you need a XBOX+Display and a copy of Forza Motorsport. When you have that, link them with Systemlink and start Forza Motorsport…then there’s a hidden option which you’ll find this way:

“Select the Options menu then scroll to the bottom of the menu. Then push the left thumbstick down and scroll down to a hidden option on the screen. You’ll see the words “Network Cockpit Settings” at the end of the list.”

Pressing the Left Thumb-Stick down…and there it is…

Configure it…and go go go…

and this is what you get, when you have 3 XBOXes and 3 Displays and 3 Copies of Forza Motorsport:

some more laser games

well…after the last news about the geeky games with lasers here are some more news. There was a 60mW one tonight… and it’s bright-as-… that’s the type of gadget that’s gonna hurt someone for sure… But it’s real fun to play with.

Oh … I almost forgot to tell the story: The guy who brought the 60mW laser talked to the dealer and that dealer referred to the other guy with the less powerful laser I wrote about recently…Because nobody talked to the dealer in the beginning we thought that he possibly read it here at schrankmonster blog… so… if you’re reading this make a comment! 😉

hax0ring the HTC Himalaya (MDA2 / XDA2)

uhh…the last 3 days I did almost nothing else than hexediting, flashing, dumping and thinking what to do more with the ROM Images I’ve got.

Maybe I have to explain:

I’ve got a new build of a new Operating System for my MDA2 Smartphone. The only problem is, that some genius at HTC (the manufacturer of the MDA2) decided that it might be a great idea to lock a major part of the ROM of the device. On the support side it’s great: It’s nearly impossible to “destroy” the device by flashing it. You always have a fail-safe mode. Even after a crash when the “100% ROM erased” line appeared won’t affect the device…just redo the flash…

But for me it’s a major problem. I am supposed to flash the new ROMs via a serial terminal (HTCs MTTY to be precise). The problem is that the only reply if the device on the flash command is “NOT ALLOW OPERATION”. Which is quite frustrating.

But there’s another way to get the data flashed. If you have the BIN file… dd / ntrw it do the SD card…SD Card into the MDA2, boot into bootloader…and voila… flash!

Okay. That’s the fast version. But stay tuned for the long version soon 😉

SD:Waiting for card insert.........

CMD3 for SD, it's OK, ready to get RCA from response.

SD:Detected one card

SD:ready for transfer OK

Total card size=1E880000

what would happen if someone hacks DCF77 time signal?

Some days ago we talked about: What would happen if someone hacks the DCF77 time signal?

If you don’t know what the DCF77 signal is, read the small description here.

Anyway: Many things are automated these days when it comes to time dependant actions. For example working time registration, backups, cash terminals just to name a few.
These services all depend on the assumption that they all have the correct time… Normally they get their standard-time from the internet or by radio (the mentioned dcf77).

In the first case I think many things will go wrong when the dcf77 time signal is manipulated… backups could be overwritten (tape overwrite protection expired…) … money wouldn’t be counted as disbursed … maybe things would just fail.

Anyway: Normally none of these speculations should be possible…but you never know…

The most interesting use of such a time manipulation is:

Almost every morning I am unable to get a parking lot for my car at the university. I would wonder if some would continue to sleep if the dcf77 time is set one or two hours behind…

Sounds not a that bad idea, doesn’t it?

We’ll see when it maybe just happens sometime.

You provide the light saber. I’ll provide the wireless LAN.

This evening the grey sky of Ilmenau was illuminated by something similar to Yodas green light saber. Actually it IS a laser of unknown power which seems to be used to “draw a straight line” above the roofs of the sleepy Ilmenau citizens.

Fortunately this is just a picture to show you what the laser should look like close-by.

And now cheer for the great pictures that where taken this night. They show the impressive skyline of Ilmenau and the even more impressive light saber by night.

Stay tuned for more light saber action…

Nerd Sport: Harddisk Speaker!

Everytime I think it could not be worse I am impressed and surprised that it can be. After the fabulous Harddisk VU-Meter built by reply2all there is another Harddisk-mod project: Harddisk Speaker.

The idea is: take a defect Harddisk. Modify the read/write head interface and it’s bearing, add a standard stereo jack: Voilà you have a Harddisk Speaker.

The (quiet) sound is made by the read/write head when it’s moved fast on the plate.

The stereo jack in my notebook…

Soldering No. 1

Soldering No. 2
(connects the head interface to the jumper pins)

Soldering No. 3
(the bearing modified to move better)

the opened drive…

Really impressive to see that that little bit of energy from the stereo jack is enough to make the read/write head move and even create a sound. You can really hear the music … louder than you would expect. Okay: Sound quality is improvable especially the lower frequencies.

RSA200 factored

Numbercruncing cereals!

"We have factored RSA200 by GNFS. The factors are




We did lattice sieving for most special q between 3e8 and 11e8
using mainly factor base bounds of 3e8 on the algebraic side and 18e7 
the rational side. The bounds for large primes were 2^35. This produced
26e8 relations. Together with 5e7 relations from line sieving the total
yield was 27e8 relations. After removing duplicates 226e7 relations
remained. A filter job produced a matrix with 64e6 rows and columns,
having 11e9 non-zero entries. This was solved by Block-Wiedemann.

Sieving has been done on a variety of machines. We estimate that
lattice sieving would have taken 55 years on a single 2.2 GHz Opteron 
Note that this number could have been improved if instead of the PIII-
binary which we used for sieving, we had used a version of the
lattice-siever optimized for Opteron CPU's which we developed in the 
The matrix step was performed on a cluster of 80 2.2 GHz Opterons 
connected via a Gigabit network and took about 3 months.

We started sieving shortly before Christmas 2003 and continued until
October 2004. The matrix step began in December 2004.
Line sieving was done by P. Montgomery and H. te Riele at the CWI, by
F. Bahr and his family."

force Spotlight to index network shares

Today I found a very interesting article on MacOSX hints. It’s about Spotlight and how to force it to index network shares.
By default Spotlight ignores NFS/SMB/AFS shares. Of course there are some problems about the whole metadata idea behind spotlight when it comes to network shares.

It’s the idea behind a network shared volume that makes it hard to be indexed by spotlight. First of all more than one user at a time has access to this volume. So at any time there can be changes made to documents on that volume. Secondly the system Spotlight is running is not informed that a document changed…
One feature of Spotlight is, that you do not have to reindex a drive. It just indexes every document when it’s created or changed on the drive. And this is impossible on network volumes. Because there’s no possibility to stay in touch with the documents like it’s on physically attached exclusive used drives (through the file system for example).

So you have to reindex manually from time to time to use Spotlight on network volumes. So here’s what to do to force Spotlight to index network volumes:

Open a Terminal and enter:

sudo mdutil /Volumes/… -i on

Great hint! Unfortunatly you have to reenable the indexing everytime you mount the drive…that’s once a week for me… so not a big problem but not perfect anyway.

UPDATE: Unfortunately Spotlight just seems to index the network volume but it does not search through this index ;-( Thats disappointing!

multeem Subversion access

Namenlos configured the Subversion server for anonymous acces. So you can now access the current development builds of multeem. Multeem is a project whose goal it is to reinvent the Instant Messaging world. Okay okay. That’s a bit to much marketing blah. I wrote about the goals and plan behind multeem some days ago. Just read this 😉

You can access the subversion server at Use the username “anonymous” and an empty password.

There are two ways to build multeem:

1. Visual Studio 2003

There’s a Visual Studio 2003 solution included. Just create a working copy from the SVN and open the multeem.sln in /multeem in Visual Studio. The solution should compile now. And you should be able to debug/run multeem.

2. Mono

We’ve included SConstruct files for the Scons Build-Tool. Just install Scons and Mono and build it 😉

We will release binaries and tarballs every now and then here on schrankmonster. So far we do not plan to maintain a dedicated website for multeem.

recordings of the 21c3 Congress are online…

The recordings of the 21c3 are online. Unfortunatly only the audio. No video so far. You can download them via bittorrent (it’s a 2.2GByte lump of data)

Malte from treehugginpussy splitted this big download into the several pieces. You can get them here.

All the recordings are in .ogg. You can grab the handouts here.

“Vom 21c3 wurden jetzt die Audiomitschnitte veröffentlicht, man kann sie mit BitTorrent herunterladen (2,2 GByte). Wer nur einzelne Beiträge sehen will, kann diese hier herunterladen, ich hab mir mal ein Verzeichnis mit den einzelnen Dateien online gestellt. Die Dateien liegen im .ogg-Format vor.
Mitschriften, soweit vorhanden, gibt es auf dem

a thriller a day keeps the doctor away

You may not know Pacific Tech’s Graphing Calculator but if you read this article and follow the link you’ll certainly know what it is and how it became what it is. And all this is packed into a very strange story:

“Pacific Tech’s Graphing Calculator has a long history. I began the work in 1985 while in school. That became Milo, and later became part of FrameMaker. Over the last twenty years, many people have contributed to it. Graphing Calculator 1.0, which Apple bundled with the original PowerPC computers, originated under unique circumstances.

I used to be a contractor for Apple, working on a secret project. Unfortunately, the computer we were building never saw the light of day. The project was so plagued by politics and ego that when the engineers requested technical oversight, our manager hired a psychologist instead. In August 1993, the project was canceled. A year of my work evaporated, my contract ended, and I was unemployed.

I was frustrated by all the wasted effort, so I decided to uncancel my small part of the project. I had been paid to do a job, and I wanted to finish it. My electronic badge still opened Apple’s doors, so I just kept showing up.”

Instant Messaging in the multi-client world

My problem is easy to explain: one user with many computers wants to use Instant Messaging…but not with multiple accounts – not with one account for each computer but with one account and one buddylist.

I have three machines with 4 monitors which makes 3 keyboards and 3 mice. It’s hard enough to get that managed – I don’t want to manage anything related to my daily tasks. I want to optimize my daily work. And therefore I want what obviously nobody wants today. Some kind of distributed Instant Messaging Network. I want something on top of the usual IM Services (e.g. MSN, ICQ, AIM, Jabber) – Let me show you an example:

Iam using all three computers – they are all signed in to the “Meta-IM-Network”. – And they all receive Events from that Meta-Network. When a buddy goes offline/online…he will go offline/online on all three machines simultaneausly. When someone writes a message to me. It will appear instantly on all three machines. When I’ve read the mail on any of the three computers the message will disappear on the other machines…

I think you get the idea. Why isn’t this possible? Why did nobody think of something like that? I want that NOW!


the perfect hotel for the Technology-Ninja of today

Tim told us his vision of the perfect „Nerd Hotel“ of today. And I totally agree with him. Everytime when I am in a hotel it’s just pain-in-the-ass to get internet access and even more painfull to get enough outlets.

He made a list what the perfect “Nerd Hotel” would at least need to qualify as one:

  1. free Internet access
  2. enough ports (RJ45/power) in a room this means:

    1. at least one port per desk/bed
    2. at least one three power outlets per desk/bed

  3. 1 notebook desk for inbed-use (per bed)
  4. a minium of 2Mbit downlink speed for the Internet access and not less than 50% uplink speed
  5. free 802.11b wireless LAN everywhere
  6. DHCP in the LAN and please no strange security behaviour…it will certainly get “fixed” by the nerds
  7. no port filtering/filtering at all
  8. 99,9 percent network reliability (power and internet uplink)
  9. no NAT for IPv4 if possible
  10. IPv6 would be fantastic
  11. internal gigabit network/fast in-house network
  12. every ethernet port is a switch-port (to prevent sniffing)
  13. DVD/CD first-aid kits at reception

I’m sure that we’ll find several more – So feel free to comment this article and tell us!

Radiation Gadget-o-rama

I found this very interesting website today: Smart Elements. You can order almost every element of the periodic table and even some isotops of elements. And there are some very interesting elements to play with… for instance those Tritium Trasers. Actually this is a gadget I probably really need because I can’t count the times I searched for the keys in the darkness…

“Traser is the generic name for glass tubes with a phosphor layer in them and Tritium gas inside the tube. They are most often seen as a type of glowing novelty keychain and in self illuminated exit signs. They are also favored by the military for critical applications where there must be illumination regardless of circumstances. They were invented in the 1960s as a reliable self powered light source for NATO. A traser consists of a section of tubular borosilicate glass, coated on the inside with a colored layor of phosphor. Borosilicate is preferred because it is a type of glass noted for its strength and resistance to breakage. In theory one could use any beta emitting gas. In practice Tritium is preferred because it is the least hazardous.”

The second cool “toy” that I found (with the help of cosrahn) on the site is Gallium. A metal whos melting point is 30 degree celsius…so indeed it will melt in my hand… I really have to get this just to play with…

Christian mentioned that they also sell Neodym NdFeB-magnets. I personally did not know what they are, but the site enlightened me and created some respect for them 😉

European Installation Bus (EIB) Research

Deka and ThamThon started to play with the brand new EIB Installation in our Office. And they really seemed to have fun B-). Well the light was switched on and off several times – if they intended that… I don’t know – but the EIB configuration looked kinda complicated.

Oh, a few words what EIB is:

“Here’s how the “intelligent” home works: The EIB system serves as the automatic controller of devices and systems in homes and apartment houses, and functional and commercial buildings. Sensors, such as motion detectors and thermostats, send impulses over a transmission medium to so-called actuators, for example. Sensors and actuators communicate with each other via four alternate transmission media.”

This is the main controller and the serial interface of the EIB. You can see the serial cable (btw: 13 Euro for 3m serial cable is dailight robbery!) and the Battery.

The switch-modules…

This is the other side of the wall:

There are numerous actuators and switches connected to our bus. But when I left nothing worked so far 😉 The problem seems to be that the Software is not that logical – or we just don’t get it 😉

And THIS is a switch… okay… 4 switches… but damn isn’t that a nerds dream! 😉

A complete review and description of the offices’ EIB installation will be available shortly.

UPDATE: kleine Lastsituation

als ich soeben mal seit langem wieder auf einen meiner Serverlein geschaut hab, hab ich direkt gesehen wieso der Rechner in letzter Zeit etwas träger reagiert als gewohnt:

So sieht eine Suchmaschine unter Dampf aus…


der Sound eines iPod Bootloaders

Tja…damals beim Xbox Bios Hack hab ich ja schon den Hut gezogen – damals wurde der unverschlüsselte Datenverkehr direkt auf den Leiterbahnen der Xbox “gemessen” und abgeschrieben… und nun hat sich jemand hingehockt und hat die iPod Firmware auf ähnliche Weise ausgelesen…

“The whole idea started last week when leachbj gave me a piece of code that caused the piezo in the iPod to make some *squeek*-sound. I played around with that code, changed some values and somehow was able to produce different sounds. Just for fun I came up with the idea of using this different sounds for transferring data. Some minutes later I dropped the idea because I thought that just won’t work and I won’t be able to write a decoder for that. Two days later I woke up and somehow just tried encoding a 32bit value into different beeps. It worked so made a loop around it to dump about 4kb of memory.”

Dämonisches in der Musik

Früher ging man hin und hat irgendwelche Schallplatten oder Kassetten rückwärts laufen lassen…und da entdeckte man seltsame Botschaften an Gott, oder schlimmer an Satan. Im Zuge der Digitalisierung scheint sich hier auch eine Veränderung einzustellen: Auch die wirren Botschaften werden in die digitale Musik eingeflochten. Und zwar über die Spektren der aufgezeichneten Werke…so zum Beispiel bei Aphex Twin´s Windowlicker Scheibe:

Track #2

Track #1

Einfach die Lieder durch ein Spektrum-Analyzer geschickt und man erhält diese doch recht klaren Bilder… und weil jeder sich das Programm downloaden kann, kann auch jeder auf die Suche nach noch mehr dämonischen Botschaften machen….

Key points for learning leetspeek

  • Numbers are often used as letters. The term “leet” could be written as “1337,” with “1” replacing the letter L, “3” posing as a backwards letter E, and “7” resembling the letter T. “0” (zero) will typically replace the letter “O.”

  • Characters of similar appearance can be used to replace the letters they resemble. For example, “5” or even “$” can replace the letter S. Applying this style, the word “leetspeek” can be written as “133t5p33k” or even “!337$p34k,” with “4” replacing the letter A.

  • Letters can be substituted for other letters that may sound alike. Using “Z” for a final letter S, and “X” for words ending in the letters C or K is common. For example, leetspeekers might refer to their computer “5x1llz” (skills).

  • Rules of grammar are rarely obeyed. Some leetspeekers will capitalize every letter except for vowels (LiKe THiS) and otherwise reject conventional English style and grammar.

  • Mistakes are often uncorrected. Common typing misspellings (or typos) such as “teh” instead of “the” are left uncorrected and may be adopted to replace the correct spelling.

  • Non-alphanumeric characters may be combined to form letters. For example, using slashes to create “/\/\” can substitute for the letter M, and two pipes combined with a hyphen to form “|-|” is often used in place of the letter H. Thus, the word “ham” could be written as “|-|4/\/\.””

SHA-1 gebrochen

Ähm… da kehrt gerade so eine Art Knappheit an Prüfsummen ein meint Isotopp….und Bruce Schneider weiss noch genaueres:

“SHA-1 has been broken. Not a reduced-round version. Not a simplified version. The real thing.

The research team of Xiaoyun Wang, Yiqun Lisa Yin, and Hongbo Yu (mostly from Shandong University in China) have been quietly circulating a paper announcing their results:

  • collisions in the the full SHA-1 in 2**69 hash operations, much less than the brute-force attack of 2**80 operations based on the hash length.

  • collisions in SHA-0 in 2**39 operations.

  • collisions in 58-round SHA-1 in 2**33 operations.

This attack builds on previous attacks on SHA-0 and SHA-1, and is a major, major cryptanalytic result. It pretty much puts a bullet into SHA-1 as a hash function for digital signatures (although it doesn’t affect applications such as HMAC where collisions aren’t important).

The paper isn’t generally available yet. At this point I can’t tell if the attack is real, but the paper looks good and this is a reputable research team.”

Heute abend: Chaosradio

und zwar nicht wie erwartet Chaosradio Nummer 100 – sondern Chaosradio 33:

“Da wir die Nr. 33 seinerzeit übersprungen haben und demnächst ein Jubiläum ansteht, wollten wir den Sack voll machen und auch wirklich 99 Sendungen gemacht haben, bevor wir den dezimalen Übertrag in Auftrag geben. Deswegen Chaosradio 33. Ansonsten bleibt eigentlich alles beim alten 😉

Das Team dieses Mal: Frank, Pavel, Tim, Max.”

Blauzahn Geschichten – Bluetooth zwischen Windows Server 2003 und Windows Mobile 2003

Nachdem gestern mein AVM BlueFritz USB 2.0 Stick gekommen ist, …

Habe ich angefangen zu probieren ActiveSync via Bluetooth mit meinem T-Mobile MDA2 zu synchronisieren. Jetzt kreuzigt mich bitte nicht . 😉 Mein Hauptsystem zum Spielen, Basteln und so ist ein Windows 2003 Enterprise. Nativ … no Bluetooth. Also steht nach der Install vom Stick nur der AVM Bluetooth Stack zur Verfügung. Gesagt getan …. Stick erkannt … “SerialProfil” ausgewählt für MDA2 aber ActiveSync will nicht. Nachdem ich nun diverse male versucht habe das ganze mit den Orginal MS Bluetooth Stack des MDA2 zu synchronosieren, habe ich mir dann heute ne WIDCOM Stack draufgehauen und siehe da. Plötzlich habe ich sämtliche Profile auf meinem MDA2 verfügbar. Standard sind wohl ObjectPush, Headset. Serial Profil gibts wohl erst nachdem man die Bluetooth Tools (Freeware Addon, nicht MS) installiert hat. Und ActiveSync funktioniert nun perfekt.


Heute Bildschirm:
man achte auf unten rechts

Komfortable Verwaltung (1):

Viele neue schöne Profile:

Komfortable Verwaltung (2):

Wieso nun der ganze Bluetooth Aufriss ???

Damit ich schön komfortabel mittels RemoteAmp mein Winamp und Itunes steuern kann. Playlist , Equalizer, MediaLibary, etc. vom MDA … alles no Prob.

Den Mediaplayer ab Version 9.x kann man auch fernsteuern. Das Tool heißt Rudeo Control.
