ACentral Configuration: Automating

This appendix describes how to set up your environment to provide your thin clients

running Wyse Enhanced Ubuntu Linux with automatic configurations in three simple

steps.

It includes:

•"How INI Files are Employed"

•"How to Set Up Automatic Configuration"

TIP: Wyse thin clients do not require device management software. They are configured to

obtain their IP address, as well as the location of configuration instructions, from a DHCP

server. However, you can use Wyse Device Manager (WDM) for a more hands-on

management of your thin clients. For information about configuring your thin clients to

communicate with a WDM server, see "WDM" and related INI parameters in Reference

Guide: Wyse ® Enhanced Ubuntu™ Linux INI Files.

INI files (created and maintained by the administrator) determine how the thin client is

configured. The thin client accesses INI files from the server during the initialization

process. Typically, INI files are accessed through FTP, HTTP, and HTTPS; if no protocol is

specified, the default is anonymous FTP.

INI files are employed as follows:

•wlx.ini - This is the global INI file. One wlx.ini file is available to all users. It contains

global parameters for all thin clients accessing the server. If the operating system

cannot find wlx.ini, it defaults to wnos.ini.

•{username}.ini - This file is unique to each user. The {username}.ini file contains the

connection profile for each user. Parameters in the user profile generally supersede

the identically named global parameters.

•$MAC.ini - This file can be used for device-specific configuration. If the thin client

locates this INI file (it is stored in the same directory as wlx.ini), wlx.ini is not accessed,

unless you use the include=wlx.ini parameter.

When a thin client is initialized, it accesses the global wlx.ini file. When a user logs in, the

thin client accesses the user’s unique {username}.ini file. For detailed information on

constructing and using Wyse Enhanced Ubuntu Linux INI files, refer to Reference Guide:

Wyse ® Enhanced Ubuntu™ Linux INI Files.

TIP: If both PNLite and a user profile are being used, the username must be defined in the

Windows domain to be used, and the password must be the same for the domain and the

profile.
