["Jorge JJ" <jfolen.sec () gmail com>]

Hi! to everybody.

When you want a ssh authentication by a public/private key. You must
leave the public key on the server and the private key in the
client... ¿how does the authentication work? ¿is the private key send
to the server (ahhh!!!)? and the best question where i can find
information about this... when i have this type of question where have
i look?

thank
