SSH Fingerprint

[Alan Gutierrez]

How do I verify the SSH fingerprint of one of the public Fedora 16 Cloud 
images when I first start it?

The SSH host keys are printed to the console during boot, so you can
use "euca-get-console-output <instance ID>" to see this.  It will have
two separate keys.  You want to add the one starting with "ssh-rsa" to
your ~/.ssh/known_hosts.  Scripting it like this worked for me:

IID=i-5b46873c  # your instance ID goes here
echo $( euca-describe-instances $IID | grep $IID | awk '{ print $4 }' ) \
$( euca-get-console-output $IID | grep ^ssh-rsa ) >> ~/.ssh/known_hosts

hope this helps.

Thank you for responding. That is what I expected to find, the server's ssh key
printed to the console output. But, I don't see it there. Not when using one of the
Fedora 16 AMIs.

Here's a gist of the output of the California hosted Fedora 16 i386 AMI ami-25e0bc60.

I'm using a small instance.

It this something that is a known issue? Or do people generally build their own instances
using BoxGrinder?

My apologies.  I was looking at the F17 beta image, not 16.  I'm not
sure what F16 usually looks like.  I'd have to go test that.
