Just-in-case anyone missed it:
Ncrack - High-speed network authentication cracker
I haven't tested it yet but someone just passed the URL along to me so I thought I'd "pay it forward" ....Ncrack is a high-speed network authentication cracking tool. It was built to help companies secure their networks by proactively testing all their hosts and networking devices for poor passwords. Security professionals also rely on Ncrack when auditing their clients. Ncrack was designed using a modular approach, a command-line syntax similar to Nmap and a dynamic engine that can adapt its behaviour based on network feedback. It allows for rapid, yet reliable large-scale auditing of multiple hosts.
Ncrack's features include a very flexible interface granting the user full control of network operations, allowing for very sophisticated bruteforcing attacks, timing templates for ease of use, runtime interaction similar to Nmap's and many more.
Ncrack was started as a "Google Summer of Code" Project in 2009. While it is already useful for some purposes, it is still unfinished, alpha quality software. It is released as a standalone tool and can be downloaded from the section below. Be sure to read the Ncrack man page to fully understand Ncrack usage.
I'm a compulsive post editor, you might wanna wait until my post has been online for 5-10 mins before quoting it as it will likely change.
I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.
