NSL Manager 1.1.3 in Mac OS 9.1
NSL Manager version 1.1.3 in Mac OS 9.1 no longer includes a DNS plug-in, and the SLP plug-in
uses a new algorithm to decide which network neighborhood to advertise a service in (see SLP
Registration in Mac OS 9.1 and Mac OS X, below).
NSL Manager 1.2 in Mac OS X
NSL Manager version 1.2 in Mac OS X uses its own SLP and NBP plug-ins for service registration
and discovery. LDAP and NetInfo searches are not supported in the first release of Mac OS X.
Setting Up Your Network to Work With the NSL Manager
How you set up your network affects which services the NSL Manager can locate. You may
need to make adjustments to allow hosts to find specific network services. Read the following
sections for protocol-specific information.
Setting Up for DNS Searches
The NSL Manager uses the DNS plug-in to find network services listed by Domain Name
Service (DNS) servers.
DNS and Mac OS 9
Your DNS server must be configured to allow anyone to request and receive zone transfers.
To make network services available to the NSL Manager through the DNS plug-in, you need to
manually add text records for network services to the DNS server. The format of the records is
as follows:
<hostname> <TTL> TXT <URL>
The following table explains each element of the record.
If you use more than one DNS server, make sure you add records for a particular host name to
the server responsible for that host and add the names of these servers to the search domain
lists in clients’ TCP/IP configurations.
DNS in Mac OS 9.1 and Mac OS X
The NSL Manager does not use DNS for service location in Mac OS 9.1 or Mac OS X.
Field Contents
<hostname> The name of the host
<TTL> The time-to-live for this information
<URL> The complete URL for this host (for example, http://www.apple.com/)
