John the Ripper

[th3p4rk2]

Hiya Guys,
My first post here, having loads of fun playing with Kali!

Im currently trying to understand how to implement rules in John The Ripper.

Essentially I have a .cap file (from my own network) and therefore know the password is 4 letters followed by 4 numbers eg ABCD1234

How do I set these parameters in JTR?

I have looked over the guides at Openwall.com (http://www.openwall.com/john/doc/EXAMPLES.shtml)

they talk about the config file, rules and give the syntax structure but I still cannot get my head around what i actually need to do to get this to work!

I also do not want to use a dictionary file as the letters at the beginning are completely random.

any guidance or links to somewhere with a simple guide and some examples would be awesome :)

Thanks in advance,

Tony

hi :)
i'm not expert but :
if this can help you && if i've understand the question :
you should need a """"custom-RULES"""" in a john.conf (and I do not know how to build :o) OR in alternative:
if the sequence of the password is ""your-posted-up"" you CAN TRY to use crunch WITH john (jumbo1.7.9[supported -fo=wpapsk && ALSO GPU_power])
for example(i don't know is "totaly-correct"):
