amazon ec2 instance access

[kalin <kalin%el.net@localhost>]

hi...

i'm a bit confused. finally accessed an aim instance of netbsd 6 on the 
amazon ws platform. usually when a new machine is installed i check the 
ssd_config first. so to my surprise i noticed this setting for root:

PermitRootLogin without-password

according to the man for ssd_config:

"If this option is set to ``without-password'', password authentication 
is disabled for root."

yet still when trying to ssh in as root i can not get access. why is that?

i did try changing it to:

PermitRootLogin no

but then the awesome thing amazon has - some java virtual console - to 
access the instance via a pem key is not working anymore... which i 
guess it makes sense. but how is that with a without-password setting in 
sshd_config i can't get in?!


thanks....
