authorized_keys2 は時代遅れなのでは

$HOME/.ssh/authorized_keys2、authorized_keys に変えた方が良い。
OpenSSH 3.0 の時点で既に obsolete 扱いですし、ver.up で authorized_keys2 を読まなくなったとしても、もはや文句言えないと思う。

2) The files
/etc/ssh_known_hosts2
~/.ssh/known_hosts2
~/.ssh/authorized_keys2
are now obsolete, you can use
/etc/ssh_known_hosts
~/.ssh/known_hosts
~/.ssh/authorized_keys
For backward compatibility ~/.ssh/authorized_keys2 will still used for
authentication and hostkeys are still read from the known_hosts2.
However, those deprecated files are considered 'readonly'. Future
releases are likely not to read these files.

不確かですが、PuTTY も authorized_keys2 は読まなくなってた記憶あります。
