How to change the private key in use and change the default public key in use?

  1. To generate the new 4192 bit key pair in the Ezeelogin jumphost installation, run the following command on the gateway server first.

/usr/local/ezlogin/eztool.php -regenerate_ssh_key

      2. Run the highlighted command using parallel shell so as to copy the new public key to all servers. The idea would be to copy the newly generated public key to /root/.ssh/authorized_keys on the remote servers.

Regenerate SSH key pair...

- New SSH key pair generated. Execute the following command on all remote servers using parallel shell feature to add the new public key in authorized keys:

echo 'ssh-rsa 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 ezlogin' >> ~/.ssh/authorized_keys

 

After it is done, press enter key to continue...

  Wait for the parallel shell execution to complete before pressing any key  to return to command line. This will ensure that the new public_key is copied across all servers.


3.  Within the Webpanel, you will see the new Public key of length 4192  bits.  In the backend, the file would be /usr/local/etc/ezlogin/id_key.pub

 

rotate key pair


4. Click "Setup SSH key on all server" to ensure that the newly generated public key is verified across all servers and the old public key removed.
