Title: Access to SSH
Post by: Fabrizio on December 13, 2002, 11:32:45 PM

Hi people,

This is my problem:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    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.
The fingerprint for the RSA key sent by the remote host is
99:a0:ed:e6:ad:cd:82:6a:30:65:22:51:a8:05:5b:80.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
Password authentication is disabled to avoid man-in-the-middle attacks.
X11 forwarding is disabled to avoid man-in-the-middle attacks.
Permission denied (publickey).

Please help me !!!

It's hard to help you if you don't say what you're doing to get this warning...

But before you did that, did you run ssh-keygen as root by any chance? That would regenerate the SSH host keys and result in the warning you received.

Or, have you re-installed the server that you're trying to connect to?

Just open this file:
   - "pico -w /root/.ssh/known_hosts"

Then delete the line that shows the server you are trying to connect to.  Save and close the file.

Try to re-connect.

Hope that helps.
