Hmmm - the first time I looked at the structure of SSH_MSG_CHANNEL_OPEN_CONFIRMATION, I thought those extra fields were for confirmation purposes and didn't give it a second thought.  Seems like the RFC should maybe state their purpose in SSH_MSG_CHANNEL_OPEN_CONFIRMATION a bit more explicitly - as is, although it's clear what they mean for SSH_MSG_CHANNEL_OPEN, for the confirmation response, it kinda requires you guess.  Maybe it's an easy enough thing to guess correctly, but I, apparently, didn't...

Anyway, thanks!
