Hi Victor,

Is this a typo?

Or did you copy directly from the console? "/etc/ssh/ssh_rsa_key" is not 
listed in your sshd_config excerpt. If sshd is really trying to 
use "ssh_rsa_key", make sure it exists in /etc/ssh/

Also, you are specifying the server HostKey and AuthorizedKeysFile as the same 
file. I don't think it will work like that.

Read up on man sshd, man sshd_config ... 

You can adjust the logging level in the config:

LogLevel DEBUG

Restart sshd then watch the log messages while you try to log in  --  syslog 
prints to tty10  (Alt+F10) [I think, at least ... I don't remember the 
default, I've changed mine to logfile]

hth,
eli
