ninja_shell v2.0

This is a custom raw socket shell aka port knoking with AES 256 CBC, https://en.wikipedia.org/wiki/Port_knocking
using specific tcp flags ,FIN,URG,PSH and use AES 256 CBC cipher at communication.

*You dont can see the PORT OPEN,only you send specific flags,
to make this you can use nemesis,hping or client.c to send commands with especific flags...

Diagram how works

to run you need use root because raw socket need:

# make

on server machine:

# bin/server

on client machine:

# bin/client SERVER__IP

if return errors at make, you need openssl lib

So to get this lib you can follow this examples:

on deb based linux follow:

# apt-get install openssl-dev

on rpm based linux follow:

# yum install openssl-devel
