...transport protocol to improve the integrity of the initial key exchange. Firstly, it requires endpoints to terminate the connection if any unnecessary or unexpected message is received during key exchange (including messages that were previously legal but not strictly required like SSH2_MSG_DEBUG). This removes most malleability from the early protocol. Secondly, it resets the Message Authentication Code counter at the conclusion of each key exchange, preventing previously inserted messages from being able to make persistent changes to the sequence number across completion o...

I'm trying to change my local setup from ssh2 to openssh-2.3.0p1. I need captive comands and specific environments for each key, i.e. the "command=XXX" and "environment=X=y" options. Unfortunately I *also* need to support the existing ssh2 client for a transition period, since it's impractical to change all user's environments to openssh in one go. I have converted
