Going through other recent flight failures I'm seeing all of these a
fair bit. Searching for this particular message led me to
https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/416264

That suggests "-o GSSAPIAuthentication=no" as a workaround.

Seems like the root cause might be to do with either reverse DNS or
perhaps AVAHI. Shall we just nix GSSAPIAuthentication?

Ian.
