Using SSH over Ethernet as Root account

Since software release VF2_515_v2.11.5, root account is no longer required for logging in Debian OS remotely. But if you still need to use the root account for privileged operations in remote access, follow the instructions in this topic.

After the new system is installed, the rejected connection denial appears when you try to log on to the Debian Linux server as a root user. Here is the example information:

$ ssh root@192.168.120.41
ssh: connect to host 192.168.120.41 port 22: Connection refused

To enable SSH root login, perform the following steps:

Run the following command to configure the SSH server:
```
~# echo 'PermitRootLogin=yes' >> /etc/ssh/sshd_config
```
Restart the SSH server:
```
~# systemctl restart sshd
```

You will be able to use SSH login using the root account. The following output indicates the login is successful:

Result:

$ ssh root@192.168.1.172
root@192.168.1.172's password:
