Remote Manager

Test Objective Covered:

  • Use NetWare Remote Manager

Remote Manager was known as the NetWare Management Portal in earlier versions of NetWare. I like to call it NORM (Novell Remote Manager). This is the most robust of the three anytime, anywhere management utilities offered by NetWare 6. You can use Remote Manager to monitor your server's health, to change the configuration of your server, and to perform diagnostic and debugging tasks.

Real World

By default, Remote Manager is installed with most NetWare 6 installation options. The one exception is the pre-migration installation option. If you use this option, you must perform the migration and post-migration tasks (see Chapter 2), and then install Remote Manager from the NetWare 6 Operating System CD.

To use Remote Manager, you must meet the following minimum system requirements:

  • Operating system—NetWare 5.1 or later.

  • Browser—Remote Manager supports one of the following three browsers: Netscape 4.5 (or later), Internet Explorer 5 (or later), or the NetWare browser (available from the server console). In addition, you must have SSL (Secure Sockets Layer) enabled on your browser.

  • NLMs—PORTAL.NLM and HTTPSTK.NLM. Fortunately, both of these Remote Manager NLMs are loaded by default from AUTOEXEC.NCF.

To access Remote Manager from any of the browsers in the preceding list, simply enter the following in the Address field:

https://{server IP address}:2200

This URL launches the NetWare 6 Web Manager (shown in Figure 3.1). The Web Manager contains links to all of NetWare 6's Web-enabled utilities. Next, select the server that you want to administer from the Remote Manager list. Accept the SSL certificate by choosing Yes, and log in as Admin when Remote Manager asks you to authenticate.

Figure 3.1FIGURE 3.1 NetWare 6 Web Manager.

Real World

In addition to secure port 2200, you can use the nonsecure port 8008 to access NoRM and then bounce over to the NetWare 6 Web Manager. This is because port 8008 automatically redirects you to a secure 8009 port. In fact, you can use port 8009 and go directly to the Remote Manager page. For additional security, you can also configure unique ports using the /ALTPORT and /SSLPORT load options with HTTPSTK.NLM.

The NetWare 6 Remote Manager window is shown in Figure 3.2. This screen is organized into five different management frames:

  • Health indicator frame—In the upper-left corner of the Remote Manager window is an overall server health indicator. This graphic also links you to a server-health monitoring page. The health indicator represents your server's condition using one of four colors: green (good health), yellow (marginal health), red (requires administrator response), and black (communication with the server has been lost and it might be down).

  • Header frame—At the top center of the Remote Manager window, the header frame contains general information about the server. It also provides links to the following management pages: Volumes, Health Monitor, Configuration, and Exit.

  • Navigation frame—On the left side of the Remote Manager window, the navigation frame lists general tasks that you can perform. In addition, it provides an outline form to grant quick access to specific management tasks.

  • Main content frame—In the center of the Remote Manager window is the main content frame. This context-sensitive frame lists details for the highlighted navigation option. The main content frame is where you'll perform most of your advanced remote management tasks.

  • Online help frame—In the top-right corner of the Remote Manager window, you can access online help by clicking on the Novell icon.

Figure 3.2FIGURE 3.2 NetWare 6 Remote Manager.

In this section, you'll learn how to perform the following administration tasks by using Remote Manager:

  • Diagnosing server problems

  • Managing servers

  • Managing applications

  • Managing server hardware

  • Managing eDirectory

Diagnosing Server Problems

Remote Manager enables you to diagnose server problems using the Health Monitor link from the main page. Generally, Remote Manager enables you to monitor the health of servers by viewing the status for all known components, troubleshoot when server health is in question (such as red or yellow conditions on a component), and run a report comparing the configuration of two servers. Table 3.1 shows a list of the most popular server diagnostic tasks available in Remote Manager.

Enables you to compare the configuration of two servers or to have a record of your server settings before making changes.


Managing Servers

The primary purpose of Remote Manager is to manage NetWare servers. As you saw in Figure 3.2, the Manage Server link is the king of the hill. Within this tool, you can accomplish a variety of critical server management tasks, including accessing the file system, maintaining SET parameters, restarting the server, building server groups, accessing other servers, and monitoring NetWare licenses.

Table 3.2 lists the most popular server management tasks available in Remote Manager.

That completes our comprehensive lesson in NetWare 6 anytime, anywhere management with Remote Manager. This Web-based advanced administration tool enables you to remotely perform almost every task that you could if you were sitting at the server console. Now let's continue our NetWare 6 remote management lesson with Novell's Internet-savvy iMonitor tool.

Brain Snack

Part of NetWare 6 remote management is "seeing what isn't there." Use the following rhyme to test your perceptivity skills:

A CNE came to the riverside,

With a donkey bearing an obelisk,

But he did not venture to ford the tide,

For he had too good an *.

What is the missing word?
