5 Configuring Advanced Server for UNIX

This chapter contains the information required to configure Advanced Server for UNIX. You must have root privilege to configure NetBIOS and Advanced Server for UNIX.

5.1 Configuring NetBIOS

The following section first gives a brief introduction to NetBIOS.

The remaining sections include the following type of information you need to configure NetBIOS:

●The second section describes how to configure network interfaces so that they can be used by NetBIOS.

●The 3rd section describes how to configure NetBIOS name resolution.

●If not stated otherwise all following descriptions imply that all NetBIOS tuning param- eters use predefined values. The fourth sections will show how – in case of need – the behavior of NetBIOS can be influenced by changing the tuning parameters.

In what follows the reader is assumed to be familiar with the basic concepts and terms of TCP/IP networking (IP addresses, netmasks, subnets etc.).
