I'm looking to tweak ubuntu cloud version default setup where is denies root login.
Attempting to connect to such machine yields:
maxim@maxim-desktop:~/workspace/integration/deployengine$ ssh root@ec2-204-236-252-95.compute-1.amazonaws.com
The authenticity of host 'ec2-204-236-252-95.compute-1.amazonaws.com (204.236.252.95)' can't be established.
RSA key fingerprint is 3f:96:f4:b3:b9:4b:4f:21:5f:00:38:2a:bb:41:19:1a.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'ec2-204-236-252-95.compute-1.amazonaws.com' (RSA) to the list of known hosts.
Please login as the ubuntu user rather than root user.
Connection to ec2-204-236-252-95.compute-1.amazonaws.com closed.
I would like to know in what configuration file the root blocking via ssh is configured and how I can change the printed message?

Old question, but no one really answered you and I have had the same question: Where does this configuration come from?
It originates from cloudinit, precisely in
cc_ssh.py
within/usr/lib/python2.7/dist-packages/cloudinit/config
This in turn is directly dependant on the file
/etc/cloud/cloud.cfg
. The you find a linedisable_root: true
.You should be able to override it by adjusting your user-data and add line
disable_root: false
. Your cloud-provider should make the user-data configurable.
