Do you have a good reason to still be using the RSAAuthentication option? It's protocol 1 only, which has been obsolete for a decade or so, and your -vv transcript shows that you're using protocol 2 so RSAAuthentication cannot possibly work. Since you're communicating with a server version that is substantially less than a decade old, there should be no reason to try to use protocol 1 with it. The protocol 2 equivalent is PubkeyAuthentication. You will of course need to make sure that you aren't using an RSA1 key (ssh-keygen -t rsa1 vs. -t rsa). -- Colin Watson [cjwat...@debian.org]
