结果却这么简单 .

Kiddie:   A friend of mine told me that it is possible to sniff on a LAN...
          so I bought a switch ;)

NaGoR:    mmhhh....

Kiddie:   Now my LAN is SECURE ! you can't sniff my packets... ah ah ah

NaGoR:    are you sure ? look at ettercap doing its work...

Kiddie:   Oh my god... it sniffs all my traffic !!
          I will use only ciphered connections on my LAN, so ettercap can't
          sniff them ! ah ah ah

NaGoR:    mmhhh....

Kiddie:   Now I'm using SSH.  My LAN is SECURE !

NaGoR:    are you sure ? look at ettercap doing its work...

Kiddie:   shit !!  grrrr...

ettercap demonstrates that now is the time to encourage research on
internet protocols to make them more secure.
