<br>
This is a simple implementation of Port Knocking techniques. <br>
This sniffs network packets with determined keys and executes commands
like firewall to open and close ports. In the client mode injects
packets with key to server.<br>

<big><b>2 - What is Port Knocking</b></big><br>
<br>
In one instance, port knocking refers to a method of communication
between two computers (arbitrary named here client and server) in which
information is encoded, and possibly encrypted, into a sequence of port
numbers. This sequence is termed the knock. The server initially
presents no open ports to a public network and is monitoring all
connection attempts. The client initiates connection attempts to the
server by sending SYN packets to the ports specified
in the knock. This process of knocking is what gives port knocking its
name. The server offers no response to the client during the knocking
phase, as it
"silently" processes the port sequence. When the server decodes a valid
knock
it triggers a server-side process.<br>
<br>
The definition of a valid knock is arbitrary, and up to the
implementer.
The server-side process is also arbitrary, and up to the implementer.
The trigger may result in dynamic modification of firewall rules or
other administrative system events.<br>
