我想调整ubuntu云版本默认设置哪里拒绝root登录.
试图连接到这样的机器产量：
- 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.
我想知道在什么配置文件中通过ssh配置了root阻止以及如何更改打印的消息？
