Hi, thanks for replying me!
Actually, my /ect/apt/sources.list is a bit different from yours.

I manually added the last line, but I haven’t touched the other ones (again, I apologize for my English). Do you think I have to change it?
By the way, if I understand correctly what you want to do, I think you can do it without updating the ssh server.
Actually, I could but it seems that my version os SSH Server is a bit old (ssh -v gives OpenSSH_5.1p1 Debian-5, OpenSSL 0.9.8m 25 Feb 2010) and I would prevent intrusions due to software vulnerabilities.
This is the output of dpkg -p openssh-server

Description: secure shell server, an rshd replacement
This is the portable version of OpenSSH, a free implementation of
the Secure Shell protocol as specified by the IETF secsh working
group.
.
Ssh (Secure Shell) is a program for logging into a remote machine
and for executing commands on a remote machine.
It provides secure encrypted communications between two untrusted
hosts over an insecure network. X11 connections and arbitrary TCP/IP
ports can also be forwarded over the secure channel.
It is intended as a replacement for rlogin, rsh and rcp, and can be
used to provide applications with a secure communication channel.
.
This package provides the sshd server.
.
In some countries it may be illegal to use any encryption at all
without a special permit.
So it’s a bit old…
Thank you again for your help!
Waiting for someone who can drive me to the solution…
