Troubleshooting: Managing NerveCenter Security

The following list contains some common security problems NerveCenter users face.

Users cannot connect to the server

Problem: Users are not members of the appropriate NerveCenter user group on the server machine (ncadmins or ncusers on UNIX or NerveCenter Admins or NerveCenter Users on Windows).

Solution: Check group membership. If users are not members of the appropriate groups, add them. Remember that on Windows, users must log out for changes to take place.

See Managing Security on UNIX or Managing Security on Windows.

Problem: Users do not have a valid Windows account.

Solution: Check the user account. See your Windows documentation for more details.

Problem: The server is not running.

Solution: Restart the server.

See Chapter 3, Running the NerveCenter Server

Users in ncadmins or ncusers on UNIX cannot connect to the server

Problem: ncadmins and ncusers have been created on a NerveCenter host that is also an NIS client.

Solution: When running NerveCenter on an NIS client, the groups ncadmins and ncusers must reside on the NIS Master. Local NerveCenter groups are ignored when the local system is an NIS client. Authentication is done on the NIS Master server. When running in an NIS environment, make sure the NerveCenter groups are defined on the NIS master. The user community members must be members of those groups as well.

See Installing NerveCenter.

Anyone can connect to a Windows server

Problem: NerveCenter was installed on Windows without security.

Solution: Reinstall the NerveCenter server with security.

See Installing NerveCenter.

User can monitor alarms, but can't modify behavior models

Problem: Users who are members of ncusers (UNIX) or NerveCenter Users (Windows) can only monitor and reset alarms. To be able to modify NerveCenter objects, users must be members of ncadmins (UNIX) or NerveCenter Admins (Windows).

Solution: Add users to the appropriate groups.

See Managing Security on UNIX or Managing Security on Windows.

User cannot connect to the NerveCenter Web client.

Problem: User does not have the appropriate permissions on the Web server.

Solution: Give the user access to the Web server. See your Web server documentation for details.
