I am following this thread with interest and like to understand too.

You three Atom, epixoip and undeath are experts and but with short, compact explanation you made us very confused. Could you please please please give us a command line as example
- how one machine can tackle this problem either GPU or CPU, even with GPU performance loss, -hence the need of 4 CPUs-
- What this member needs to do so 4 machines can tackle together this problem.

thank you very much for your help.

I'm not sure I understand the question properly but here is an example how to split a brute force up between 4 computers.

This is how to do it for WPA.

To make it easier to explain this is supposing you want to brute force numbers only against WPA at length 8. Also this is for windows 32bit. So you need to check what you are running.

It's unfortunate that 10 isn't easily divided by 4 ! Smile

oclHashcat-plus32.exe -a 3 --hash-type 2500 -1 ?d -2 01 test.hccap -o Found.txt ?2?1?1?1?1?1?1?1
oclHashcat-plus32.exe -a 3 --hash-type 2500 -1 ?d -2 234 test.hccap -o Found.txt ?2?1?1?1?1?1?1?1
oclHashcat-plus32.exe -a 3 --hash-type 2500 -1 ?d -2 567 test.hccap -o Found.txt ?2?1?1?1?1?1?1?1
oclHashcat-plus32.exe -a 3 --hash-type 2500 -1 ?d -2 89 test.hccap -o Found.txt ?2?1?1?1?1?1?1?1

I think that's right, someone will probably point out if it isn't ! Smile

Ok, that's a start!

Please, if you know, answer me the following questions:

1 - Each line is to be used in each computer, right?

2 - The "-a 3" is the type of attack, right? Brute-force in this case?

3 - The "--hash-type 2500" is self-explanatory.

4 - What mans this "-1"

5 - What means the "-d" at this position?

6 - What means the "-2" at this position?

7 - I gently ask you to explain how do you divide the task as it is in the "01", "234", "567" and "89"

8 - The "-o file.txt" is also self-explanatory.

9 - The "test.hccap" would be the file with the hash, right?

10 - The "?2?1?1?1?1?1?1?1" would be the mask, right? But i see that you have a ?2 and a ?1, meaning that you have 2 charset, right? In the command where are those 2 charsets? Are they the -1 ?d and -2 01 (2- 234, and so on)? I'm confused because this is setted in the GUI command line as --custom-charset1 and --custom-charset2...

Many thanks
