Using Bash

--From what I can see, both "vncrack" and "hydra" are CRACKER'S TOOLS.

--We do **not** support illegal activity on this board.

--If you have a legitimate use for these tools, I suggest you speak up real quick, or be prepared to get banned by the admins.

I don't know about those particular tools but I find that attitude rather naive.
A good way to find holes in your system is to try to crack it yourself using the same tools an attacker might me using. For instance users with bad passwords can be a problem in some environments, in such cases a smart admin runs a password cracker on his own /etc/shadow file and takes action (lock the account & notify the user or something like that) if weak passwords are found.
