Rafael, Sorry I misunderstood you earlier. Unfortunately I don't think it's possible to use JtR's default "Single Crack" mode where it switches between single ruleset and incremental mode automatically, (plus uses username and GECOS info), along with the --stdout option. If you manually want to do it though, you can get a rough simulation by running the single ruleset in wordlist mode and then incremental mode using the --stdout option. Aka: ./john -stdout -wordlist=username_gecos.dic -rules=single | awk '{i++;if (i>1000000) { exit 4; } print}' | ./john -session=real -stdin -format=raw-md5 test_passwords.dmp *figure out how many guesses were made for the new limit... ./john -stdout -incremental=ALL | awk '{i++;if (i>NEW_LIMIT) { exit 4; } print}' | ./john -session=real -stdin -format=raw-md5 test_passwords.dmp That being said, it's almost certainly easier just to go with Magnum's option.
