First : thank you everybody for all your work !
At now I am not able to see the difference. But I think I may not doing the
right thing in order to test :
wget "http://launchpadlibrarian.net/254059000/openssh-client_7.2p2-4_amd64.deb";
dpkg -i openssh-client_7.2p2-4_amd64.deb
ssh-keyscan -v -t dsa -H -p 22000 -T 5 test.[snip]
debug1: match: OpenSSH_6.7p1 Debian-5+deb8u3 pat OpenSSH* compat 0x04000000

==> OpenSSH_6.7p1 is not the right version... although :
ssh -V
OpenSSH_7.2p2 Ubuntu-4, OpenSSL 1.0.2g 1 Mar 2016
root@ghu-thinkpad:~# dpkg -l | grep ssh
ii libssh-4:amd64 0.6.3-4.3
amd64 tiny C SSH library (OpenSSL flavor)
ii libssh-gcrypt-4:amd64 0.6.3-4.3
amd64 tiny C SSH library (gcrypt flavor)
ii libssh2-1:amd64 1.5.0-2ubuntu0.1
amd64 SSH2 client-side library
ii openssh-client 1:7.2p2-4
amd64 secure shell (SSH) client, for secure access to
remote machines
ii python-paramiko 1.16.0-1
all Make ssh v2 connections with Python (Python 2)
ii sshpass 1.05-1
amd64 Non-interactive ssh password authentication
It may be due to the libssh that I have not updated ?
RQ : I preafer to install updated packages directly rather than playing with
dpgk database (I may be wrong on this point).
Thank you for your help.
B.R.
Gautier.
