Decrypt WEP Key the air* suite

A friend wanted to see how to use airodump and aircrack to decrypt a wireless LAN WEP key so I quickly made up this movie, which shows how to identify wireless networks, how to sniff the packets and how to use aircrack to get the key out of the dump file. happy watching!

Internetausbau in Deutschland

Ich musste einen Kurzvortrag in Sozialkunde ausarbeiten, der sich mit einem aktuellen Thema beschaeftigt. Meine Wahl fiel schliesslich auf den Plan 100 % Deutschlands mit Breitbandinternetzugang (Geschwindigkeit > 1 Mbit/s) auszustatten. Dieses Projekt wird von der Regierung gefoerdert und soll bis 2010 abgeschlossen sein. Beigefuegt finden Sie das Handout und die Statistiken dazu. Mein Vortrag war frei und ohne jegliche ppt. Themen wie “Digitale Dividende” oder “Bandbreiten International” wurde gesondert behandelt, so dass das Referat netto knapp fuenf Minuten in Anspruch nahm und die Fragerunde im Anschluss ca. 20 Minuten. Ich hoffe das Handout bietet Informationen fuer andere in einer aehnlichen Lage. new1

HiPath Xpressions

How to export specific lines from a text/log file into a new text file using a DOS batch.

One of my customers using the AppGen on OpenScape Xpressions V5.0 R3 (MRS. 7.11) had a pretty usual query; they wanted to get a report that displays every call that hit the Auto Attendant outside the business hours. The CDR crew could not really get it done because the call is not in every case forwarded to the voicemail I had to find a way in Xpressions. There is a flag now you can set on the boxes that is called Generate raw data for statistics that is checked by default.


Looking into the installation dir you will see a folder e.g. c:\siemens\xpr\Stat which contains all of those log files. Unfortunately there are a couple of other entries in that file than the one with the inbound call function. It content looks like this:

Telematic    Physical Lines    2009.    System=1    Mode=I    Board=4    Channel=2    Used=1    Total=2    BoardID=1I4    Status=IN
Telematic    Physical Lines    2009.    System=1    Mode=I    Board=4    Channel=2    Used=0    Total=2    BoardID=1I4    Status=FREE
Telematic    PHONEMAIL    2009.    Access=CB    Caller=+123456789    Lang=2057    Time=47    Errors=0    Result=UD    Call=    Mailbox=180    Sent=0    Count=1    Age=0    Diff=1
Telematic    Event    2009.    Protocolname=PHONEMAIL    Source=TUI    ScriptID=3    NumSubscribers=307
Telematic    Call    2009.    Protocolname=PHONEMAIL    Source=TUI    ScriptID=3    NumSubscribers=307    Subscriber=Ger Reynolds    Extension=+123456789    UserId=180    Caller=+123456789    AccessMode=CALLBACK    Duration=47    Success=UNKNOWN
Telematic    Call Processing Call    2009.    Protocolname=PHONEMAIL    Source=TUI    ScriptID=3    NumSubscribers=307    Success=COMPLETED    Type=VOICE
Telematic    Physical Lines    2009.    System=1    Mode=I    Board=5    Channel=1    Used=1    Total=30    BoardID=1I5    Status=IN
Telematic    IVR Box    2009.    UniqueID=4611767028170358873    BoxName=Timeprofile    BoxType=TIME    StartTime=2009.    Duration=0    DTMF=    ASRKeyword=    ASRConfidence=    ACDGroup=    TimeProfile=BAUSCHLOMB    Result=STATE BREAK    NextBox=Menue_1_Good_Evening    ForwardNumber=    Script=

So I had to find a way to separate the lines that contain the information “Status=IN” which stands for an inbound call into the box. In order to get this done I created a batch file that is using a command I published already in the Windows 2003 basic administration guide on that website.
Create a batch file and name it for example export.bat and put it into the Xpressions installation directory (C:\siemens\xpr\export.bat) and enter the following lines:

echo off
REM Stop Xpressions
net stop mrs
REM Create backup Folder
mkdir statbackup2
REM Backup Status Files
xcopy /E statbackup\*.log statbackup2
REM Remove old status files
del statbackup\*.log
mkdir statbackup
REM Backup Status Files
xcopy /E stat\*.log statbackup
REM Find Incoming call and export into text file
find "Status=IN" stat\*.log > data.txt
REM Remove log file
xcopy /E data.txt data_old.txt
del data.txt
REM Remove old status files
del stat\*.log
REM Start Xpressions
net start mrs
REM Finished

This batch is stopping the Xpressions in order to close the connection to the log file, backs the files up and reads the information using find “Status=IN” stat\*.log and outputs it into the file data.txt. After the file is created it deletes the content of the stat folder and starts Xpressions again. In this case you have no duplicate entries in the data.txt file on the next export. Schedule this task to repeat itself daily for daily statistics.

Tomorrow I will show you how to import that collected data into a mysql database using the same batch file and setup a small query page to access this information that will look like this: (This is still Alpha 1 release and a lot of work has to be done!)


Synchronise Windows Server 2003 DC with external time source automated

Almost every site I go to has the same problem, the time on the phone display does not match the time on the PC screen. What are the reasons for that issue? Well first of all you have to understand how the time system in your PBX and your Windows environment are working.
The phone system (PBX) usually gets its time signal from an external source and is not configured manually. In 90% of the cases I configure my customers to use the ISDN trunk as time source. The time the provider provides on that line is 100% accurate and you receive it without delay. The time is updated every time a user establishes a phone call.
The Windows Domain has its own time server. By default this is the Domain Controller or Operations Master. This servers provide time to the other clients in the network but are by default not configured to update their information from an external time source and the admin has to set the time manually or the time will just go wrong after a couple of month operation but no one cares or knows what to do.
The following batch script is what I use to solve this problem and setup a link to an external time source that is updated every hour. On your DC just create a new text file rename it to time.bat and open it with an editor of your choice. Enter the following commands:

echo off
w32tm /config /syncfromflags:manual /
w32tm /config /update
w32tm /resync

They will set the time source to the Microsoft NTP server ( which is default on a workstation and will resynchronise the time with this server. Now all you need to do further is to setup a scheduled task to repeat this every hour or at least daily.

As alternative you can set your PBX to sync with the DC as well just change the NTP setting on it, but I cannot recommend a solution with wrong time information. Look @ Microsoft for further information on that.

New web page layout

After more than a year with Nathans ElegantBlue template I decided to move on to a totally new style. After browsing the wordpress template page I found what I was looking for. A very flexible one developed by BytesForAll. I modified the header a bit to suit the content of the website and changed a couple of the html files for a nicer translation. I hope you enjoy the new design and I hope I can start blogging a bit more…



A couple of things to do…

After a couple of years working with already built applications and doing website programming with simple XML and PHP one of my friends inspired me to try something new. So I got myself the new Adobe Flash CS 4.0 and just finished downloading Microsoft Visual Studio Express 2008. This is going to be quite some learning curve but I want to start studying application engineering or media design. I did my first moving flash application which is just a small little icon flying around but if you are a real beginner this can be pretty tricky already. One thing I want to show is just how disappointed I am from While downloading the new Visual Express 2008 my downstream was limited to 100kb/s so I tried it from a server and look at the difference of the download speed for the German and the English Visual Studio…



Another file found on my HDD

While deleting old backups I found this old Counter-Strike preview movie of my former mutligaming clan. This video is about four years old and was the preview to the official terraX CS movie which was unfortunately never released.

OpenScape ComAssistant V2.0

Below you find a video that shows you the look and feel of the call management using the OpenScape ComAssistant V2.0 R4.1.0. It is a basic licensed system, so the features Team View and Xpressions Integration are not working.
