Nice little applet I came across:
long high is yours? Is there such a test for writing C/C++/C# code?
Weren’t we promised a watercooled 360 at first hand? There was this fabulous ourcolony movie for the viral marketing. And the guys there, which were supposed to be the engineers of the 360, said “and it’s got water inside”…pointing at the watercooled 360 mainboard and showing it into the camera…
Nothing of that became true as of today. The Retail-360 is a air-cooled gaming console with no water inside at all. But just till the guys from HardOCP got their hands into the game. They’re presenting you a watercooled 360 running at astonishing low temperatures:
“With stock Xbox 360 cooling, after an hour of Quake 4, the back of the motherboard temperature was 150.8ºF ( 66ºC ).
With the water cooled Xbox 360, after an hour of Quake 4, the back of the motherboard was a full 50ºF cooler than stock cooling at 101ºF ( 38.4ºC ).”
Well..that makes 442 connected clients at the maximum peak… nifty!
Harald brought this to my attention:
“Pervasive computing will more and more influence on the everyday life because more and more electronical devices are capable of speaking IP, e.g. via Ethernet, WiFi or Bluetooth. Vibrators will be no exception. Although people haven’t realized this yet, there are in fact already vibrating devices with IP-connectivity called mobiles or cellulars. The AT command specified in GSM 07.07 does only provide a command to enable the vibrating on an incomming phone call. Therefore the controlling of these vibrating devices is rather clumsy.”
The Motorola A780 has some nice details:

22. Chaos Communication Congress
Scanning your GPRS/UMTS IP network for fun and profit
We are giving an overview of ip networks used for >=2.5G technologies. Our main focus is on scanning the overlaying ip network, on different Voice-over-IP filter implementations and the possibilities to circumvent them.
We want to explain the ip networks used in GPRS and UMTS cellular networks from the enduser point of view. How do they work today and what has to be done to get a normal webpage, voice-over-ip or even a video stream onto your PDA or SmartPhone.
For your private investigations inside your providers ip network we want to demonstrate you a tcp/udp port and round-trip-time based traceroute program based on the .NET compact framework. With the help of this program we want to analyse the anti voice-over-ip filters implemented by different cellular providers and show you some possibilities how to circumvent them _efficently_. So we don’t just tunnel all the traffic through a VPN. But even when these filters become more sophisticated in the future we want to present some ideas how to defeat your right to talk via voice-over-ip whereever and whenever you want to.

As promised yesterday here are some more information about the video and audio streaming and recording at the 22c3. First let’s start with the almost complete scheme:
What’s not in the scheme is where and how the streams are recorded:
there’s a DV tape in every camera (we’ve got 400 brand new DV tapes for that purpose here)
audio+video streams are recorded on the CCC encoding machines on their local hard drives (MPEG2 audio and MPEG4 video)
audio+video streams are record on the FeM encoding machines on their local hard drives (Windows Media Audio+Video 9)
audio-only streams are recorded on the CCC streaming servers local hard drives
Last but not least: How can you watch and hear those fantastic streams? Easy:
go to http://22c3.fem.tu-ilmenau.de and take a look or follow the links directly to the WMV streams:
or go to http://184.108.40.206/ and take a look or take this table:
|hall||OGG/Vorbis HQ||OGG/Vorbis LQ||MP3 HQ||MP3 LQ||RTSP MP4V MPGA|
We only had the time to test one lecture hall today – and this is our current setup which worked quite good:
A complete listing from where to where the signals are routed will be available tomorrow.
…and the mandatory panoramic views:
Since we are kind of interested in providing a large user DECT network on the campus of our university we spoke with the Eventphone guys about their setup: and as far as we can tell it’s far more sophisticated than expected.
Well sorry that there are more pictures than text – it’s just because we have to compile all the information we got and pile it all together into a nice and well understandable text for your reading pleasure.
Well here we are – packed with equipment we arrived in Berlin and successfully tested the first encoding-run for the upcoming 22c3 which starts in two days.
Since we arrived we unpacked all the equpiment and drawn-in our new “office” for the next days: the video studio – which is kind of above/around hall 1.
so here we are… on the right side you can see into hall 1 through the window.
Funny thing beside that: we got our own /24 subnet here – peered with 10GE directly to the Berlin CIX. How cool is that 😉
So here are some information about how we are planning for the 22c3.
MPEG2 Multicast (3-4 Mbit)
available only in the internal 22c3 network
available everywhere – server inside the 22c3 network and one or more servers in the internet
live OGG/MP3 audio casts
congress-tv – available standard PAL tv signal of each talk in the congress center
untagged (without comments/naming…) available in the 22c3 network hopefully immediately(within 2-3 hours) after the talk
tagged available via ftp/torrent… when it’s done
WMV downloadables/on-demand streams
untagged available immediately (see above) for download and live stream
tagged available via on-demand live stream and downloadable when it’s done
OGG/MP3 audio casts (will also be available via a podcast on schrankmonster)
I did not write for over a week now – I simply had no time to write – but now I want to give you a short update on what happened the last days:
2. December: the 360 arrives. I had only some time to unpack and testdrive PGR3 – in fact it’s what was promised – the next generation gaming console. (please make a firmware update so that the DVD drive is more quiet).
yes, there’s an apple keyboard attached to the 360.
To raise the pain-bar the desperatly needed XBOX VGA cable is not available anywhere around. I actually have to wait till it’s available again. Until then I am using the 360 via PAL-60 – which is – oh well …
There are some nice and some bad things to say about the 360 – one thing I just found out and impressed me: when you want to type – let’s say in XBOX live – you might want to use the on-screen keyboard. But when you attach a commonly used USB keyboard to the 360 – you can use it for the typing job … I wasn’t expecting that.
late last week I attended the 3rd “Speakers Acting” Training held by Vision Voices Executives Alexandra Schwarze and Martin Marx. As you can imagine it was a fantastic and enriching experience.
And the this weekend it finally happened: SIXT gave me my the first V6 – a Mercedes Benz ML320 – what a … hell of a car.
hmm… a SUV at >220 km/h… hrhr eat this mother nature!
Oh, I almost forgot to tell you what I did with the addictive ML – We took a trip to Berlin to meet with the guys of the Chaos Computer Club Berlin who are organising the 22th Chaos Communication Congress. As things work out we will be in Berlin at 25th of december with 10 people – recording and streaming the whole congress for you. Working closely together with the guys from congress-tv, congress-streaming… I can only cross fingers and hope that everything is going to happen as planned and discussed.
What a great contest! Get your Photoshop started and create a world “if the hackers rule”.
“Remember when computer hackers were the big scare? Sure they might be 15-year-olds computer nerds who t41k 2 mUc4 l1k3 7h15!!!!!!!!!!!!11 [talk too much like this]. But that doesn’t mean that, with a few deft keystrokes, they couldn’t take over the world. And what would everyday life be like then? Get ready for some l337 h4xx0r1ng!!!!!!111 [elite hacker language].
The rules of this game are thus: In this contest you will show us images from a world run by l337 hax0rs. Your images should ideally focus on something that already has text on it. (i.e. a shampoo bottle with instructions written in html or the Coca-Cola logo written in poorly spelled gibberish). As always, quality is a must. We will remove poor entries no matter how much we like you. You’ll have 48 hours for this contest, so make your submission count.”

This year more than any year before the 22nd Chaos Communication Congress needs your help!
Since FeM e.V. plans to help the team of the 22c3 with equipment and manpower there never can be enough hands to help at such a big event.
If you want to assist and help us recording and streaming the whole congress than surf to the official 22c3 wiki and state your intention to help by contacting the orga-team telling them that you want to be a videoangel.

On the way back home I came past a house where one particular window attracted my interest. A huge 1337 is in bright letters in that window. Obviously some elite hackers are living there…
When I made the pictures I noticed that just one floor down right from my elite window another obviously rich students are watching tv on some kind of big ass tv – probably a projector…
Since I don’t have the space (and money) for such artefacts as a big ass tv – I am just jealous with the guys…I want one for my 360… okay let’s start small: I want a 360!
It’s time for another What The Hack wrap-up session: (slides are in german)

Hmm..how many wires do you need to connect a doorbell? You need 8 wires of course! Do we actually have any cables !=CAT5/5e/6 ?
After several weeks of waiting today the JASJAR / MDA pro arrived together with the T-Mobile UMTS contract + USIM.
As you can imagine the unpackaging was quite an event (I am not posting the pictures that show me retardedly smiling)
Since ahzfs JASJAR also arrived today and the third one is on it’s way and expected to arrive on monady we now can just start over developing the applications for our research project.
Surprisingly Blinkenlights is back for our viewing and gambling pleasure. If you are in Berlin these days, make sure you’ll take a look.

It’s not that long ago that ID Software released the sourcecode of Quake III: Arena. Since the release many people worked on the sourcecode and one particular man did a very good job by porting Quake III to the Xbox:

After some minutes the job was done – and openwrt instead of the original firmware was flashed into the two new linksys routers.
Please welcome OpenWrt – “White Russian RC2”.
Since the documentation is quite good it just leaves me with this citation:
“With the release of the Linux sources for the Linksys WRT54G/GS series of routers came a number of modified firmwares to extend functionality in various ways. Each firmware was 99% stock sources and 1% added functionality, and each firmware attempted to cater to a certain market segment with the functionality that they provided. The downsides were twofold, one – it was often difficult to find a firmware with the combination of functionality desired (leading to forks and yet more custom firmwares) and two – all the firmwares were based on the original Linksys sources which were far behind mainstream Linux development.
OpenWrt takes a different route, instead of starting out with the Linksys sources, the development started with a clean slate. Piece by piece software was added to bring the functionality back to that of the stock firmware, using the most recent versions available. What makes OpenWrt really unique though is the fact it employs a writable filesystem so the firmware is nolonger a static compilation of software but can instead be dynamically adjusted to fit the particular needs of the situation. In short, the device is turned into a mini linux PC with OpenWrt acting as the distribution, complete with almost all traditional linux commands and a package management system for easily loading on extra software and features.”
My Linksys WRT54GS-DE router arrived! So tomorrow we’ll start to put the openWRT on it…
I really need a “every-firewall-detour-device”…more on that and on the thingies you can do with such a device later on.
So this is part 2 of my little “how to transform a Windows Server 2003 Web Edition into a Windows Server 2003 Standard Edition if you only have Remote Desktop and limited “physical” keyboard access to the machine…
Since some hard-drive imaging experiments did not work today I decided to try the straight-forward way. Mounting the CD and installing…
I came across several problems and had to find a workaround or them. The first problem showed up: Since we would like to have Remote Desktop Access after the installation finished successfully installing a Windows Server 2003 Standard Edition WITH Servicepack 1 is not an option. One of the new features of Servicepack 1 is that after a clean Install you cannot access the machine from the network anyhow – You have to update the machine and then this “feature” disables itself.
So it is important that you have a non-SP1 Windows Server 2003 Standard Edition Install-CD…
Another problem occurs now if your currently running Windows 2003 Web Edition has Servicepack 1 installed already…
If you start the setup something like this will show up:
“Setup cannot continue because the version…”
So we’ll have to trick a little bit to fake a pre-SP1 environment for the setup: When you start the setup the “winnt32.exe” is launched which loads the “\Windows\AppPatch\sysmain.sdb” file and reads the version number that is stored there.
The trick is to replace the running systems “sysmain.sdb” with the one from the setup CD. (don’t get confused that the path is “C:\noSP1\” – just replace that with your CD-Drive name).
Anyway…just do this:
One note to the things above: the file is deleted from the dllcache first to trick the Automatic System File Protection…
Once you have completed this you can start the setup and it’ll run as desired. Ensure that you select the following advanced options:
“Copy all installation files from the Setup CD”
Now start the setup, fill in the product key and wait until the machine reboots.
If you had KVM access you’ll see this after the reboot:
Now it’s going to be fun! My ISP allows me to send keyboard commands to the machine… so this are the commands you’ll have to send (blind!) to finish the installation:
Enter (Welcome to Setup)
Escape (don’t repair)
C (Continue Setup)
L (Delete Windows folder)
After about 25 minutes and a reboot
Enter (Regional Configuration Dialog)
Enter (Licensing Modes 5 concurrent connections)
password (your actual password…I recommend to leave it “password” or any other simple thing…
Tabulator (retype the password)
Enter(confirm the passwords)
Tabulator(that’s the password warning “Password to simple” if you’re absolutely sure this won’t come up…skip this and the next one)
Enter (password warning)
Enter (Timezone settings)
Enter (Typical Network Settings)
Enter (Workgroup name)
After about 30 minutes the machine reboots
After the machine rebooted it should be pingable…if so you should enable Remote Desktop Access remotely:
Step 1: start “regedit” on your local machine
Step 2: connect to the IP of your machine and login with username+password
Step 3: Change HKLM\System\CurrentControlSet\Control\Terminal Server\fDenyTSConnections from 1 to 0
Step 4: connect with your Terminal Service Client.
Now you should have this…
And that’s it as simply as it could be B-). One way to get Windows Server 2003 Standard Edition on a Windows Server 2003 Web Edition machine…
okay…the straight “insert CD and start the setup”-Way to update from Web Edition to Standard Edition is dead end…:
but after some minutes the machine reboots and you see:
…and that’s the point where you would need physical access to the machine – or at least have KVM-access to the machine…so…we’ll try another strategy…
It seems that we finally got the right place for your weekly meetings…
Today nierenschaden finally got the tent’s FTP Server up and running so we can mirror and host the talk recordings that are available about an hour after the talk ended….
After we announced our server (which has about 750 GB of storage) many people dropped in to leech from our mirror…
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-)
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.
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”…
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.
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…

And there are some scheduled or semi-scheduled meetings. If you would like to contact me you’ll probably find me at the FeM Village between the talks and of course by eMail.
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.

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?
Itanium 2 32 Bit CPU Emulation?
oh and there’s some storage space:
More on that … later 😉
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.
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… 😉
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:

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! 😉
For somewhat reason ahzf needs some of those sophisticated little buggers called SOEKRIS… well he told me some story about some wireless LAN stuff… so that could be one reason. This explaination is supported by the fact that he also ordered 15 Atheros B/G WLAN Mini-PCI adapters… possibly he is reading this and give a complete overview and explaination for us in the comments…
On 1700 the second FeM e.V. FIWAK started. To explain it short what that is:
Around 40 people go into the forest. Take a power generator and a huge number of network and computer equipment with them. 3 big tents and several small ones… of course Wireless LAN Internet access everywhere…
