Hi all,

I just tried to run famous john password cracker on my multicore system. I 
discovered, that john is using only one of my two cpus (100 percent). The 
other one seem to work for other tasks (0 - 20 percent). 



So, must I compile john in another way ?

Must I start john in another way ?

Must the source code of john be written in another way ?


Hi
usually to use multi-processor system it's necessary that the source is 
written to do it.

Certainly, but if john is eable to run from another point (i.e another
dictionary) is posible to run a second instance of the program from
another point and really do parallel process...

Well sure, but if its not written to do that, they you have to rewrite
it to do so.  You have access to the source.  Go for it.
