Anyone know how to set up jtr to do a simple dictionary attack instead of incremental. I just starting using this damn thing and it seems it takes 3-8hrs to crack simple hashes.

I've tried john-386 mypass takes for ever. also tried using -si & -w but nothing comes of it.?????????? What the f%&% am I doing wrong?

                                  THANKS,

-w:wordfile here. example:

cd /usr/root/john-1.6
john -w:password.lst pass.txt

where /usr/root/john-1.6 is your JTR install. you are using the JTR wordlist file. and your user hash is in pass.txt in the JTR directory.

example pass.txt

whihc is in the form user:pass I know you know this stuff its for other people.

Ok for everybody out there the secret to jtr is finding a good wordfile I tried quite a few and was taking for ever, tried a different one and it took less than a second to crack. If all else fails you can go incremental but sit back and wait it will be a while.

Thanks WillieH for info!

just cd to that where the john program is in and type john, hit enter. Then, it will give you the different commands john has. Mine is actually, for this wordfile thing:

john-386 -wordlist=new_wordlist.txt

john-386 is the program name, -wordlist is the switch for using a wordlist, and =new_wordlist.txt is the filename of the wordlist. If it is not in the directory, then just put the full directory location, like:

john-386 -wordlist=c:\files\new_wordlist.txt

or whatever.
