All of you who had installed backtrack would notice that at default wicd network manager applet won't shown in the panel. Well this won't affect the stability of the system but it would be quite annoying when you have to open it from the main menu everytime you want to connect to a WiFi network.

Follow this steps to fix it.

Yay, finally Mr. Onno W. Purbo will come to my university to give a seminar about Information Security. Mr Onno W. Purbo is a well known IT Expert in Indonesia.

More interesting thing, anything he is talking is about OpenSource. I can say that he's the father of OpenSource in Indonesia. More info about Mr. Onno W. Purbo can be found in wikipedia.

Hex Generator

Finding bad character when developing an exploit is important to make the exploit works properly as we want. In my post about searching bad character I used a perl script to generate a series of hex character start from 00 to FF. Here's other script used to generate it. I found the script at this site. It is written in python language.

Download here.

Script:

#HEX Generator

#http://www.digital-echidna.org

#0x04112011

def gene():

        c=0

        x=0

        hslgen='"'

        while x <= 255:

          hslhex=hex(x)

          if c == 16:

            hslgen=hslgen+'"\n"'

            c=0

          if x <= 16:

            hslgen=hslgen.replace('0x','\\x0')

          hslgen=hslgen+hslhex

          x+=1

          c+=1

        print "\n#Generated with dE HEX Generator"

        print "#http://www.digital-echidna.org\n"

        print hslgen.replace('0x','\\x')+'"\n'

if __name__ == "__main__":

        gene()
