netcat

Some people say "netcat" is the second most powerful networking tool, the first being "nmap". That is true.

Netcat can pick any TCP or UDP port for initiating a connection to any host. This way, it acts as a powerful network client. With multiple IP addresses binded to a host, we are free to choose which IP address to use for inbound and outbound connections. When the listen mode (-l) is enable, it acts as a server.

I should have practsied netcat a long time ago. Can't recall why I miss the opportunity to play around with netcat.
