Introduction

The Security group includes the following configuration options:

zServices—This configuration window is used to enable/disabled client

and daemon services that run in the IOLAN. See Services on page 127

for more information.

Services

Overview

Services are either daemon or client processes that run on the IOLAN. You can disable any of the

services for security reasons.

Functionality

If you disable any of the daemons, it can affect how the IOLAN can be used or accessed. For

example, if you disable the WebManager service, you will not be able to access the IOLAN with the

WebManager. If you disable the DeviceManager service, the DeviceManager will not be able to

connect to the IOLAN. If you do not want to allow users to Telnet to the IOLAN, you can disable the

Telnet Server service; therefore, disabling daemons can also be used as an added security method for

accessing the IOLAN.

By default, all daemon and client applications are enabled and running on the IOLAN.
