On this page you can control two settings:

  • Change Default SSH Port.

  • Allow/Disallow Root Login.

SSH Keys

To add your SSH keys, you first need to generate a pair of a public/private key.

On your local machine

cd ~/.ssh
ssh-keygen -t rsa -f cyberpanel -C root

This will generate two files cyberpanel and cyberpanel.pub.

You need to copy contents of cyberpanel.pub and paste in the following box:

I have cyber panel login access but I am not logging in. After disabling SSH permit root login the login page is not opening. And if you login with putty software, you will not login.

#7

You need to contact your service provider in that case, they can help you recover the access. Not much CyberPanel can do if you don’t have access to CyberPanel

I got the same issue here,

Is there has anyone solved the issue?

The login page is not displayed, but I still have access via SSH

#15

the main problem is login page cannot be accessed, it just blank

#16

I got the solution

To enable permit root login in CyberPanel, follow these steps:

  1. Log in to your CyberPanel server as the root user.
  2. Open the SSH configuration file using a text editor, such as Nano:

Copy code

nano /etc/ssh/sshd_config
  1. Locate the line that reads “PermitRootLogin no” and change it to “PermitRootLogin yes”.
  2. Save and close the file.
  3. Restart the SSH service to apply the changes:

Copy code

systemctl restart ssh

This will disable root login via SSH for your CyberPanel server. Please note that you should still be able to log in as the root user using other methods, such as the console or a terminal emulator. It is generally considered a best practice to disable root login via SSH for security reasons.

But I still have an issue where the login page cannot be accessed

#17

When i paste my public key and click SAVE then i receive error:

“Could not connect. Please refresh this page.”

Why? How to fix it? I cant add key.

Generate new Keys pair, add the .pub content to cyberpanel ssh key value. Should be ok. Once you can login. Go ahead delete the old one
