Re: amazon ec2 instance access

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?!


You need to have whatever keyfile (.pem file, most likely) you set up for the instance, and log in thus:

ssh -i keyfile.pem root@<>

...and you can get it. The "without-password" setting is to allow key-only logins. Once you're logged in, you can set things up however you like.
