The only note I have is the one I posted earlier. On Machine B (the 
target system), add these two lines to /etc/ssh/sshd_config

PubkeyAcceptedKeyTypes +ssh-rsa
HostkeyAlgorithms +ssh-rsa

But others have warned that RSA is untrustworthy or obsolete, so I am 
assuming that while this may work, it is not optimal, and there may be 
some other step required on new systems.
