Supported directory drivers

Supported directory drivers

There are three supported drivers:

•interfaces driver

•Lightweight Directory Services driver.

•Cell Directory Service (CDS) provided by Distributed Computing Environment (DCE)

This remainder of this chapter describes the interfaces file and provides specific configuration information for each supported UNIX platform. For information about LDAP drivers, Cell Directory Services, and for a comparison between interfaces files and LDAP directory services, see the Open Client/Server Configuration Guide for your platform.

Contents of an interfaces file

An interfaces file contains network information about all servers on your network, including Adaptive Server, Backup Server, and XP Server, plus any other server applications such as Monitor Server, Replication Server, and any other Open Server applications.

The network information in the file includes the server name, network name or address of the host machine, and the port, object, or socket number (depending on the network protocol) on which the server listens for queries. See “Understanding the format of the interfaces file” on page 55 for the specific makeup of the interfaces file entry.

Each entry in an interfaces file can contain two types of lines:

•Master lines, which are used by server applications to listen for queries over the network. This information is called a listener service.

•Query lines, which are used by client applications to connect to servers over the network. This information is called a query service.

The network information contained in the master and query lines for a server is identical because a server listens for connection requests on the same port that clients use to request connections.

A server needs both master and query lines in its interfaces file, since servers sometimes act as clients to other servers.
