Dell NetWorker 19.9 Administration Guide

Changing the NetWorker Authentication Service hostname and port number

When you install the NMC server software, you specified the hostname of the NetWorker Authentication Service and the port number that the service uses for communication. Perform the following steps to change the host that provides user authentication to the NMC server.

1. Connect to the NMC server with an Administrator account on Windows or the root account on UNIX.
2. Stop the EMC gstd process:
   • Linux—/etc/init.d/gstd stop
   • Windows—Stop the EMC GST Database Service service.
3. From a command prompt, to change the NetWorker Authentication Service host that is used by the NMC server, type the gstauthcfg command.

   The location of the gstauthcfg command is not in the path by default and differs on Linux and Windows:

   • Linux—/opt/lgtonmc/bin
   • Windows—C:\Program Files\EMC NetWorker\Management\GST\bin

   For example:

   gstauthcfg -c -t -h New_authentication_service_hostname -p port_number
   

   NOTE:The default port number is 9090.
4. Start the EMC gstd process:
   • Linux: /etc/init.d/gstd start
   • Windows: Start the EMC GST Database Service service.
5. To establish the trust, type the following command on each NetWorker Server that is not local to the NetWorker Authentication Service that NMC uses for authentication:

   nsrauthtrust -H Authentication_service_host -P Authentication_service_port_number
   

   where:

   • The location of the nsrauthtrust command differs on Linux and Windows:
     • Linux—/usr/sbin
     • Windows—C:\Program Files\EMC NetWorker\nsr
   • Authentication_service_host is the hostname of the NetWorker Server that authenticates the NMC Server host.
   • Authentication_service_port_number is the port number used by the NetWorker Authentication Service. The default port number is 9090.

   For example:

   nsrauthtrust -H nwserver.corp.com -P 9090

6. Grant the NetWorker Authentication Service user groups access to the NetWorker Server, by typing the nsraddadmin command:

   nsraddadmin -H Authentication_service_host -P Authentication_service_port_number

   For example:

   nsraddadmin -H nwserver.corp.com -P 9090

   The nsraddadmin command updates the following user groups:

   • Application Administrator—Adds the distinguished name (DN) of the NetWorker Authentication Service Administrators group.
   • Security Administrator—Adds the DN of the NetWorker Authentication Service Administrators group.
   • Users—Adds the DN of the NetWorker Authentication Service Users group.
7. Connect to the NMC server GUI with a user that has the NMC Console Security Administrator role.
8. When prompted to create a service account for the NMC server in the NetWorker Authentication Service database, click OK.
   NOTE:If you do not create the service account, the NMC server cannot monitor events or gather reporting data from the managed NetWorker servers.
