WARNING: DO NOT DO THIS IN PROD == THAT WOULD BE BAD, RAY
This is just something I just need to remind myself of from time to time. Nothing to see here… yet.

As root, edit /etc/ssh/sshd_config

Add a line in the Authentication section of the file that says

PermitRootLogin yes

Save the updated /etc/ssh/sshd_config file.

Restart the SSH server:

service sshd restart
