Question:

When connecting to a ssh remote terminal or using ftp for file transfer, an ordinary user can log in remotely, but a root user fails authentication and prompts for a password error. And we can normally switch to root users under the login of ordinary users, su root, and verify the password.

Solution:

1. Cd / etc/ssh, change to the following directory:

2 、 sudo vim sshd_config

As shown in the figure, add PermitRootLogin yes

3. Restart the ssh service: sudo service ssh restart

Try the ssh or ftp remote connection again and you will have normal access.
