XO laptop / Pi Zero share Chromium and Desktop

XO / Raspbian ssh protocol default mismatch with Raspbian of Nov 2018.
XO default is 1 and Raspbian no longer accepts 1. 
There is a commented out Protocol line in /etc/ssh/ssh_config on both and sshd_config on Raspbian.
Match with protocol 2 or 1 or 2,1  .
