About
The nc package contains Netcat (the program is actually nc), a simple
utility for reading and writing data across network connections, using
the TCP or UDP protocols. Netcat is intended to be a reliable back-end
tool which can be used directly or easily driven by other programs and
scripts. Netcat is also a feature-rich network debugging and
exploration tool, since it can create many different connections and
has many built-in capabilities.
You may want to install the netcat package if you are administering a
network and you'd like to use its debugging and network exploration
capabilities.
Why CRLF option?
Most of the services from Internet (HTTP, POP3, SMTP, etc..) are using text based protocol with CRLF line-ending, but
the original nc doesn't support it. Here you can download the nc completed with an option (-C) to send CRLF at the end
of each line.
The codes are based on the orginal version 10.1 from freshmeat (1996), the original version 0.7.1 from sourceforge and on the version 1.84 from openBSD used by RedHat
