I think you might want 

-oHostKeyAlgorithims=ssh-dss

Which is what I use for an old machine we have at work which would give the
same message and was solved with that solution. 

You can even put it in $HOME/.ssh/config

Host 192.81.129.86
HostKeyAlgorithims=ssh-dss


This is what I use on a FreeBSD host to reach a FreeBSD guest, and it works
without problem.
