user for live migration

[embb]

Greetings,

I've successfully setup a 3 nodes cluster on online.net using tinc tunnel.
I was able to change the default port for ssh changing the sshd_config and ssh_config.

However I would like to know if is possible to use another user (rather than root) to perform live migrations because I would like to disable ssh access to root user to follow best practices on security.

Is this possible ?


Thanks in Advance

Hi embb,

Why not disable password authentication for user root and go with it? Then you can only log in via key.

You can also configure ssh in such a way, that you only allow root access from specifiy IPs. Please refer to sshd_config manpage.
