TP 3: Working with netfilter and libnetfilter-queue

The objective of this TP is to work with netfilter kernel module creation and user-space processing of queued packets using libnetfilter-queue. 

Important: The result of this TP should be sent to: [email protected] or [email protected] with TP3-yourname as a subject. 
If you don't finish on time, consider it as a homework and send it before Friday April 15 at 8:00PM. 

Context:
--------
Whenever the host receives an incomming ssh connection (on port 22), the module drops the packet.
