Set root to log in with ssh under ubuntu

By default, Ubuntu does not enable the root user and does not allow root remote login.

Enable root user: sudo passwd root //It is enabled after changing the password.




1 Modify the ssh configuration file
$ sudo vi /etc/ssh/sshd_config
Find the PermitRootLogin no line and change it to PermitRootLogin yes

2. Restart the openssh server
$ sudo service ssh restart

After that, you can use the ssh software to connect to the server.
