Services
240 IOLAN SDS/SCS/STS/MDC User’s Guide, Version 4.0
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 WebManager (HTTPS and HTTP) services, 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, except IPsec, and running on the IOLAN.

Telnet Server Telnet daemon process in the IOLAN listening on TCP port 23.
