There was mention of this a short while back, but I saw no resolution.
Starting somewhere aroudn NetBSD 1.6S, Openssh no longer works with
ssh2 in that an ssh2 connection to NetBSD 1.6S+ results in:

 Authentication successful.
 Disconnected; protocol error (Corrupted MAC on input.).

This happened on every box that I updated to -current around that
timeframe (and hasn't changed with newer releases.  Did anyone
discover what the problem is?

Thanks
