Novell Doc: OES 2 SP3: Getting Started with OES 2 and Virtualized NetWare - Setting Up the Server as an SLP Directory Agent

1.8 Setting Up the Server as an SLP Directory Agent

For OES 2 services to work, the OES 2 server must have one of the following:

An eDirectory replica installed on the server. This is not automatic after the third server installed in a tree because it is not recommended to have more than three to five replicas in the tree.

This means that in a large network with many servers, most of the servers won’t have replicas, which leaves only the OpenSLP option.
OpenSLP running on the server with eDirectory as a registered service. This requires that you configure a network server (for example, the first server in the tree) as an SLP Directory Agent (DA), and then configure the other network servers that don’t have an eDirectory replica to point to the DA server.

For the getting-started lab setup, you don’t actually need SLP services set up because each of the two getting-started lab servers (this server and the NetWare VM) has an eDirectory replica. However, it’s important to understand the basics of setting up SLP on OES 2. For more information, see SLP in the OES 2 SP3: Planning and Implementation Guide.

Log in to the server as root.
Configure the server as an SLP DA server:
1. Click Computer > Home Folder.
2. In the left panel, double-click File System, then double-click the etc directory.
3. Scroll down to the slp.conf file, right-click the file, and select Open with gedit.
4. In slp.conf, find the following line:
  
  ;net.slp.useScopes = myScope1, myScope2, myScope3
5. Remove the semicolon (;) and change the line as follows:
  
  net.slp.useScopes = Directory
6. Find:
  
  ;net.slp.isDA = true
7. Remove the semicolon (;) so that it reads:
  
  net.slp.isDA = true
8. Save and close the file and the file browser.
Configure the firewall on the DA server to allow SLP daemon traffic:
1. Click Computer > YaST Administrator Settings, then click Security and Users > Firewall.
2. In the left navigation frame, click Allowed Services.
3. Click the Services to Allow drop-down list and select SLP Daemon.
4. Click Add > Next.
5. Click Accept.
Restart OpenSLP and eDirectory:
1. Click Computer > Gnome Terminal.
2. At the command prompt, enter the following command to restart the SLP daemon with the changed configuration:
  
  rcslpd restart
3. Restart eDirectory by entering the following command:
  
  rcndsd restart
  
  This registers eDirectory as an SLP service.
Verify that OpenSLP is running as expected.
1. After eDirectory restarts, enter the following command:
  
  slptool findsrvs service:ndap.novell
  
  After a moment or two, the system should respond with a line that indicates EXAMPLE_TREE is being advertised as a service in SLP.
2. Close the terminal by entering the following command:
  
  exit
Continue with Accessing iManager.
