3.2 Installing and Setting Up Your Novell Messenger System

You should have already reviewed Section 3.1, Planning Your Novell Messenger System and filled out the worksheet. The following sections guide you through the installation process:

3.2.1 Installation Prerequisites

Before starting the Messenger Installation program, make sure that your system has been prepared for the Messenger system configuration for which you have planned:

  • Make sure that the container object exists where you want to create your Messenger system.

  • If you are planning to have the Messenger agents use LDAP access to eDirectory but you are not providing a root certificate, make sure that your LDAP server supports clear text passwords. In ConsoleOne, check the properties of the LDAP Group object that your LDAP server is a part of. Depending on your version of eDirectory, the Allow Clear Text Passwords option should be selected or the Require SSL/TSL option should be deselected.

  • If you are planning to install the Windows Messenger agents as Windows services and you do not want them to run under the local system account, make sure that the account you want them to use has been created on the Windows server.

  • If you are running the Messenger Installation program at a Windows workstation or server, make sure that you are logged in as an Admin equivalent to the eDirectory tree where you are planning to create your Messenger system. If you are installing the Messaging agents on a Windows server, you should run the Installation program at that server.

Follow the setup instructions for the platform where you are creating your Messenger system:

Configuring the Linux Messenger Agents for SSL

The Messenger Cross-Platform client requires an SSL connection with the Messenger agents. If you are not already familiar with SSL, or if SSL is not already set up on your system, you can add SSL security to your Messenger system, as described in Establishing Messaging Security with SSL Encryption in Managing the Messaging Agent in the Novell Messenger 2.1 Administration Guide.

NOTE:The Messenger Windows client does not require an SSL connection with the Messenger agents.

The required SSL connection is most easily configured in ConsoleOne. On Linux, ConsoleOne does not automatically authenticate to any eDirectory trees when it starts, so the NDS object is not immediately expandable.

Figure 3-4 ConsoleOne on Linux

  1. In ConsoleOne, select NDS, then click File > Authenticate.

  2. Fill in the following fields:

    Login Name: Provide a Novell eDirectory username that has rights to modify eDirectory objects.

    Password: Provide the password for the username.

    Tree: Type or select the eDirectory tree where you created your Messenger system.

    If the eDirectory tree is located on a Windows server, you might need to specify the IP address of the server instead of the tree name.

    Context: Provide the full context of the User object associated with the username you provided.

  3. Click Login.

  4. Under the NDS object, select the tree where you created your Messenger system.

  5. Browse to and right-click the Server object in your Messenger system, then click Properties.

  6. Click Server > Security.

    Security property page

  7. Fill in the fields (worksheet item 15).

  8. Click OK to save the security settings.

  9. Continue with Starting the Linux Messenger Agents.

Starting the Linux Messenger Agents

To start the agents manually, use the startup scripts provided in the /etc/init.d directory.

  1. At the Linux server, become root by entering su and the root password.

  2. Change to the /etc/init.d directory.

  3. To start the Messaging Agent, enter the following command:

    ./novell-nmma start

  4. To start the Archive Agent, enter the following command:

    ./novell-nmaa start

    You can also use the stop, restart, and status options for these agents from the same directory.

    Messenger agent log files are created in /var/opt/novell/log/messenger directory. The Messenger agents can be monitored by using the agent Web consoles from your Web browser, as described in Using the Messaging Agent Web Console in Managing the Messaging Agent in the Novell Messenger 2.1 Administration Guide.

    For additional agent startup alternatives, see Starting the Messaging Agent and Starting the Archive Agent in the Novell Messenger 2.1 Administration Guide.

  5. Skip to Section 3.4, What’s Next.

3.2.4 Setting Up the High Availability Service

  1. Become root by entering su and the root password.

  2. Copy the novell-groupwise-gwha RPM file to your local drive.

  3. From the location that you copied the novell-groupwise-gwha rpm, enter the following command to install the gwha service.

    rpm -Uvf novell-groupwise-gwha-7.0.xxxxxxxx.i386.rpm

  4. Modify the GroupWise High Availability service file (gwha):

    1. Change to the /etc/xinetd.d directory.

    2. Edit the gwha file in a text editor.

    3. In the port = field, specify a unique port number, for example 8303.

    4. Save the file, then exit the text editor.

  5. If you use SSL, you need to modify the High Availability service configuration file.

    1. Change to the /etc/opt/novell/groupwise directory.

    2. Edit the gwha.conf file in a text editor.

    3. Under the [gwha] section, fill in the fields as follows:

      [gwha] ssl      = yes key      = filename.key cert     = filename.crt password = password

    4. Save the file, then exit the text editor.

  6. Enable the High Availability service:

    1. In YaST, click Network Services > Network Services (inetd).

    2. If necessary, select Enable to activate the list of services.

    3. Scroll down to the gwha line, select it, then click Toggle Status (On or Off) to change the status to On.

    4. Click Finish.

  7. Start the agents as daemons.

    1. Change to the /etc/init.d directory.

    2. Enter the following commands to start the Messaging Agent and the Archiving Agent:

      ./novell-nmma start ./novell-nmaa start

    3. If the agents started correctly, a message displays indicating “Done.”

  8. Create a new user and associated password on your Linux server to represent the High Availability service.

    You might name it gwha.

  9. Test your configuration of the High Availability service.

    NOTE:If you configured the High Availability service for SSL, you cannot use a telnet session to test it. The connection will be refused. You can try to test it by killing the PID for the Agents and watch for Monitor to restart the Agents.

    1. Telnet into the High Availability server.

      For example, on the Linux server where you have configured the High Availability service, you could use the following command:

      telnet localhost port_number

      Use the unique port number you specified in Step 4.c.

    2. Specify the username and password you set up in Step 8.

      If telnet returns 000 Ok, then the gwha service is configured correctly.

    3. To exit the telnet session, press Ctrl+].

3.2.5 Setting Up Non-root Access on an NSS Volume on Novell Open Enterprise Server Linux

When the Novell Messenger agents are located on a Novell Open Enterprise Server (OES) Linux NSS volume, you must create an eDirectory user for the agents to run as, and you must LUM-enable that user. On OES Linux, you can use Novell iManager to accomplish these tasks.

After you have installed the agents on OES Linux, you need to configure the agents to switch users after startup and provide access to an NSS volume.

Creating an eDirectory User

You might want to create a new user specifically for the Novell Messenger service, perhaps named novellmsgr.

  1. On the Open Enterprise Server Welcome page in your Web browser, expand Network Management, then click iManager 2.5.x.

  2. In the iManager Links box, click Open Novell iManager 2.5.

  3. To log in to iManager, specify a username, a password, and a tree.

  4. In the left pane, expand Users, then click Create User.

  5. Provide the required information, then click OK.

    The user does not need a password.

Enabling a LUM User

To LUM-enable the user you just created:

  1. In the left pane, expand Linux User Management, then click Enable User for LUM.

  2. Browse to and select the user you just created, then click OK.

  3. Browse to and select a primary group for the LUM user.

  4. Select /bin/false as the desired shell (because the LUM user does not need a shell), then click OK.

Configuring Novell Messenger for the NSS Volume

After you have finished LUM-enabling the eDirectory user, you need to set the user as the default user for the Novell Messenger service. In addition, you need to change the store path, queue path, and log path to be on the NSS volume

Changing the Service User

  1. In a terminal window, enter the following command:

    cd /etc/opt/novell/messenger

  2. Using a text editor, edit the uid.conf file, remove root as the user, and add the LUM-enabled user.

Changing the Store Path

  1. In ConsoleOne, log in to the eDirectory tree containing your Novell Messenger service.

  2. Browse to the File Module object, right-click it, then select Properties.

    The File Module object is located at eDirectory Tree > Messenger Service > Messenger server > Archive Agent > File Module.

  3. Change the Store Path to the NSS volume, then click OK.

Changing the Messenger Agent Queue Path

  1. In ConsoleOne, log in to the eDirectory tree containing your Novell Messenger service.

  2. Browse to the Messenger Agent object, right-click it, then select Properties.

  3. Change the Queue Path to the NSS volume, then click OK.

Changing the Archive Agent Queue Path

  1. In ConsoleOne, log in to the eDirectory tree containing your Novell Messenger service.

  2. Browse to the Archive Agent object, right-click it, then select Properties.

  3. Change the Queue Path to the NSS volume, then click OK.

Changing the Messenger Agent Log Path

  1. In ConsoleOne, log in to the eDirectory tree containing your Novell Messenger service.

  2. Browse to the Messenger Agent object, right-click it, then select Properties.

  3. Change the Log Path to the NSS volume, then click OK.

Changing the Archive Agent Log Path

  1. In ConsoleOne, log in to the eDirectory tree containing your Novell Messenger service.

  2. Browse to the Archive Agent object, right-click it, then select Properties.

  3. Change the Log Path to the NSS volume, then click OK.

Granting Access to the LUM-Enabled User

The new LUM-enabled user must have rights to the store, queue, and log paths on the NSS volumes.

In a terminal window, use the following command to grant the user the required rights to the directories that the agents need to access on the local server:

rights -f /directory -r rwcemf trustee user.context.tree

When you have finished changing the rights to the directories, you must stop and then start the agents.
