Remote Maintenance Login user

During installation the enebular-agent installer automatically creates a user named enebular-remote-admin that can execute root commands. This user's password is the one specified with Installation Instructions-Options.

Change the password for the Remote Maintenance login user

If you have not specified the password for the Remote Maintenance login user in --remote-maintenance-user-password on the Installation - option page, please change the password.
For security reasons, it is recommended that you change your password.
The following is an example of a command to change the password.
You need to login to the device using the Remote Maintenance function before executing the following command.
See Remote Maintenance - Maintenance Procedure for instructions on how to login to the device using the Remote Maintenance feature.

• To change the password, execute the following command

  sudo passwd enebular-remote-admin
  

• Enter enebular when you see [sudo] password for enebular-remote-admin:. ``` We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things:

  1) Respect the privacy of others.

  2) Think before you type.

  3) With great power comes great responsibility.

[sudo] password for enebular-remote-admin: {enebular}

- You will be prompted for a password, enter any password you wish.

Enter new UNIX password: {enter any password you wish} Retype new UNIX password: {enter any password you wish} passwd: password updated successfully
