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. Protocols supported include RDP, SSH, http(s),
SMB, pop3(s), VNC, FTP, and telnet.

to fully understand Ncrack usage.
