Putty is using ssh2. So if the key of the remote host is not found in
known_hosts on the mswindow station, why does nobody complaints? When
will the key of the remote host be added in this file known_hosts?
following this doc here after your assumption is not correct, or do I
understand something wrong?
If you reinstall, the reinstalled system creates a new set of
identification keys. Any clients who had connected to the system with
any of the OpenSSH tools before the reinstall will see the following
message:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle
attack)!
It is also possible that the RSA host key has just been changed.
also if your read this
The first time you ssh to a remote machine, you will see a message similar
to the following:
The authenticity of host 'penguin.example.net' can't be established.
DSA key fingerprint is 94:68:3a:3a:bc:f3:9a:9b:01:5d:b3:07:38:e2:11:0c.
Are you sure you want to continue connecting (yes/no)?
Type yes to continue. This will add the server to your list of known hosts
(~/.ssh/known_hosts) as seen in the following message:
Warning: Permanently added 'penguin.example.net' (RSA) to the list of
known hosts
none of this happens on this server or on the mswin pc
