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 NT).

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

See Managing Security on UNIX or Managing Security on Windows NT.

Problem: Users do not have a valid Windows NT account.

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

Problem: The server is not running.

Solution: Restart the server.

See 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 NT server

Problem: NerveCenter was installed on Windows NT 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 NT) can only monitor and reset alarms. To be able to modify NerveCenter objects, users must be members of ncadmins (UNIX) or NerveCenter Admins (Windows NT).

Solution: Add users to the appropriate groups.

See Managing Security on UNIX or Managing Security on Windows NT.

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.
