Software Requirements and Conventions Used

Software Requirements and Linux Command Line Conventions
Category	Requirements, Conventions or Software Version Used
System	Installed or upgraded Ubuntu 20.04 Focal Fossa
Software	SSH
Other	Privileged access to your Linux system as root or via the `sudo` command.
Conventions	# – requires given linux commands to be executed with root privileges either directly as a root user or by use of `sudo` command $ – requires given linux commands to be executed as a regular non-privileged user

Open the /etc/ssh/sshd_config file with administrative privileges and change the following line:
```
FROM:
#PermitRootLogin prohibit-password
TO:
PermitRootLogin yes
```
The quick way to do this job could be just to simply use the sed command as shown below:
```
$ sudo sed -i 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config
```
Restart SSH service:
```
$ sudo systemctl restart ssh
```
By default the root’s password is not set on Ubuntu 20.04 and the error message Permission denied, please try again will appear when attempting to SSH login as a root user. From this reason we need to set root’s password. When prompted enter your current user password followed by new root password:
```
$ sudo passwd
[sudo] password for linuxconfig: 
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
```
