Configuring the Device Server
34 IOLAN Device Server User’s Guide, Version 1.0
Device Server Services
In order to be as flexible and accessible as the Device Server is, it can run several predefined daemon
and client applications. The Device Server can run the following daemon applications:
zTelne tD
zSPCD (the Trueport daemon)
zDeviceManagerD
zHTTPD
zSNMPD
If you disable any of the daemons, it can affect how the Device Server can be used or accessed. For
example, if you disable HTTPD, you will not be able to access the Device Server with the
WebManager. If you disable DeviceManagerD, the DeviceManager will not be able to connect to the
Device Server. If you do not want to allow users to Telnet to the Device Server, you can disable
TelnetD; therefore, disabling daemons can also be used as an added security method for accessing the
Device Server.
The following client applications can run on the Device Server:
zSyslog
zDHCP/BOOTP
If you do not have a DHCP/BOOTP server in your network, we recommend that you disable the
DHCP/BOOTP service to speed up Device Server reboots (otherwise, the Device Server waits for a
DHCP/BOOTP packet until it times out on a reboot).
By default, all daemon and client applications are enabled and running on the Device Server.
Trueport
The Trueport utility acts as a com port redirector that allows applications to talk to serial devices
across a network as though the serial devices were directly attached to the server. You can map the
baud rate of the host COM port to a higher baud rate for the serial line that connects the serial device
and the Device Server. You must be running the Trueport daemon on the host that is accessing the
serial device for this to work. See Trueport on page 115 for more information about the Trueport
utility.
Hardware Configuration
Configure the ethernet interface that is connecting the Device Server to the LAN and the serial cable
that is connecting the Device Server to the serial device.

Ethernet Connection

You need to know the ethernet interface speed and duplex as follows, unless you are using the Auto
detect option:
z10 Mbps half or full duplex
z100 Mbps half or full duplex
