Double printed ssh VisualHostKey

$ grep VisualHostKey .ssh/config
VisualHostKey yes

When connecting to a server (6.6p1 as well), the client prints the fingerprint and hostkey before authentication, and then after authentication it doubles up, trying to print the fingerprint and show the hostkey again, but with weird spacing/alignment.

What is the commandline you were using when this triggered? Could you please provide some debugging output ("ssh -vvv user@host").

I suspect the the multiple display of the fingerprint could be caused by rekeying (which causes the hostkeys to be sent again). This multiple display should be fixed in openssh-6.7 that was just released this week.

ssh -vvv

yes, that is rekeying. This is fixed in openssh-6.7 or later.
