- To disable root login, open the main ssh configuration file /etc/ssh/sshd_config with your choice of editor.
- # vi /etc/ssh/sshd_config
- Search for the following line in the file.
- #PermitRootLogin no
- Remove the ‘#‘ from the beginning of the line. Make the line look like similar to this.
- PermitRootLogin no
- Next, we need to restart the SSH daemon service.Now try to login with root user, you will get “Access Denied” error.
- # /etc/init.d/sshd restart
- So, from now onwards login as normal user and then use ‘su’ command to switch to root user.
