openssh bugs - Sep 2003 - [Bug 666] 'BatchMode yes' makes ssh(1) look for /usr/local/etc/ssh_known_hosts

http://bugzilla.mindrot.org/show_bug.cgi?id=666

           Summary: 'BatchMode yes' makes ssh(1) look for
                    /usr/local/etc/ssh_known_hosts
           Product: Portable OpenSSH
           Version: 3.7.1p1
          Platform: Alpha
        OS/Version: OSF/1
            Status: NEW
          Severity: critical
          Priority: P2
         Component: sshd
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: mmokrejs at natur.cuni.cz


When there's no /usr/local/etc/ssh_known_hosts and ssh_config says:
"BatchMode
yes", the clients get:

$ ssh bontebok
Host key verification failed.
$


When the file is present with the public key of target machine, user receives:

debug1: SSH2_MSG_KEX_DH_GEX_INIT sent
debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY
debug3: check_host_in_hostfile: filename /home/users/mokrejs/.ssh/known_hosts

debug3: no such identity: /home/users/mokrejs/.ssh/id_dsa
debug2: we did not send a packet, disable method
debug1: No more authentication methods to try.
Permission denied (publickey,password,keyboard-interactive).
debug1: Calling cleanup 0x1200708e0(0x0)



If the key in /usr/local/etc/ssh_known_hosts is wrong, it ssh(1) should say so.

This is correct behaviour. In BatchMode, you don't get asked if you want to
add
the key. The error message is correct. The key is not "wrong", it is
absent
entirely.

If you are complaining about the authentication failure in the debug trace, that
has nothing to do with BatchMode and nothing to do with known_hosts.

(I was expecting rather more from bug #666)
