Password guesser?

Does anybody know of a program or something that will allow me to put in many possible combinations of usernames and passwords and enter them to just try to figure out which password is right? I am constantly getting locked out of the system so a proxy would be awesome built in. I just need to get my old accounts up and running.

 

Or maybe you could read my post and not spam my thread accusing me of bs?

 

This seems more like cracking to be honest even though you may have a legit purpose. Sorry, but we do not support this type of discussion. Closed.
