I installed cloud-in-a-box/fastrack of Eucalyptus and am able to create instance and log into it. But when trying sudo, sudo su - or login in as root I'm asked for a password. I'm not sure what the password might be. Does anyone know what the default password for the Image is?
I think this is how the image is designed. It uses the cloud-user account only and has no root access, nor does it allow sudo.
There are other starter images available that can be "installed" that have sudo as root enabled. In those cases you simply issue
sudo su -
and you become root.
To see what is easily available use:
eustore-describe-images
As a note, some of the other starter images have different accounts (not cloud-user), such as ec2-user. If you don't know which account to use simply try to ssh into the instance as root and it will usually get a message back telling you:
Please login as the user "ec2-user" rather than the user "root".
