>Description:
With recent openssl update, i can't connect from/to my NetBSD/amd64 box
anymore. All connections fails with the same message:

njoly@lanfeust [~]> ssh -v xxx.sis.pasteur.fr

I checked that all `openssl speed' tests pass correctly ... It worked
perfectly before recent openssl update.

>How-To-Repeat:
Try to connect from or to a -current NetBSD/amd64 box using ssh.
>Fix:
Don't know.
