Setting Up Slp On Oes 2 Sp2 - Novell OPEN ENTERPRISE SERVER 2.0 SP2 - UPGRADING TO OES-PLANNING AND IMPLEMENTATION GUIDE 12-2009 Implementation Manual

On NetWare, SLP services are integrated with and configured to automatically work with
eDirectory and other services; if eDirectory is configured correctly, the services work without SLP.
If you have a NetWare tree, you automatically have Novell SLP on your network and you can
continue to use it as the SLP service during your upgrade to OES 2 SP2. If you decide to use
OpenSLP, NetWare servers can also be configured to use OpenSLP.
The Novell version of SLP takes certain liberties with the SLP standard in order to provide a more
robust service advertising environment, but it does so at the expense of some scalability. For a
discussion of SLP and OpenSLP and references to documents essential to understanding the
protocol, refer to
Guide.
SLP on OES 2 SP2
Novell provides a basic level of SLP support when eDirectory is installed on an OES server. OES
servers are configured with an SA that registers SLP-aware applications (such as eDirectory) with
the server.
However, you should configure OpenSLP (the default SLP service for OES), especially if you are
installing more than three servers in a replica ring or eDirectory partition. The first three servers in a
replica ring or eDirectory partition have an eDirectory replica installed automatically. The fourth
and subsequently installed servers in a replica ring or eDirectory partition must have SLP configured
for all services to work properly.
Caveats
DA synchronization is not part of OpenSLP.
If you are running NetWare 5.1 in your tree, it must be at SP8 to have SLP version 2
functionality. Older versions are not compatible with OpenSLP running on OES 2 SP2.
If your workstations can connect to the server using its IP address but not its DNS name, you
need to update to Novell Client 4.91 SP5 or later. See

Enabling Multicasting
SLP relies on multicasting; however, most Linux systems are not configured, by default, to provide
multicast support. Enter the following at the shell prompt to determine whether multicasting is
supported:
route -n
If multicasting is supported, you see an entry in the routing table for the 224.0.0.0 destination.
