            Bug ID: 2194
           Summary: Supress VisualHostKey message when re-keying
           Product: Portable OpenSSH
           Version: 6.4p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org
          Reporter: gturner at unzane.com

When using VisualHostKey=yes config option, during re-keying the
fingerprint message is printed, clobbering the terminal.

I'd like to see the VisualHostKey when connecting, but not at rekey
events (unless using -v of course), also if the host key changes it
would probably be better to disconnect (unless
StrictHostKeyChecking=no?).

This may be fixed by bug #2154 - Avoid key lookup overhead when
re-keying.
