[hostfile.c hostfile.h sshconnect.c]
print out all known keys for a host if we get a unknown host key,
see discussion at http://marc.theaimsgroup.com/?t=101069210100016&r=1&w=4
the ssharp mitm tool attacks users in a similar way, so i'd like to
pointed out again:
A MITM attack is always possible if the ssh client prints:
The authenticity of host 'bla' can't be established.
(protocol version 2 with pubkey authentication allows you to detect
MITM attacks)
