Accessing the NVG Cluster

To enable better NVG management and user accountability, five categories of users can access the NVG cluster:

•Operator is only granted read access to the menus and information appropriate to this user access level. The Operator cannot make any changes to the configuration.

•Administrator can make any changes to the NVG configuration. Thus, the Administrator has read and write access to all menus, information and configuration commands in the NVG software.

•A Certificate Administrator is a member of the certadmin group, and has sufficient user rights to manage certificates and private keys. By default, only the Administrator user is a member of the certadmin group. To separate the Certificate Administrator user role from the Administrator user role, the Administrator user can add a new user account to the system, assign the new user to the certadmin group, and then remove himself or herself from the certadmin group. For more information, see “Adding a New User” (page 81).

•Boot user can only perform a reinstallation. For security reasons, it

is only possible to log in as the Boot user through the console port using terminal emulation software. The Boot user password cannot be changed from the default ForgetMe.

•Root user is granted full access to the underlying Linux operating system. For security reasons, it is only possible to log in as the Root user through the console port using terminal emulation software. Root user access should mainly be reserved for advanced troubleshooting purposes, under guidance from Nortel customer support.

For more information, see “How to Get Help” (page 14).

Access to the NVG command line interface and settings is controlled through the use of four predefined user accounts and passwords. Once you are connected to the VPN Gateway through a console connection or remote connection (Telnet or SSH), you are prompted to enter a user
