hosts \sys\net A file with a manually built list used to resolve an IP address to a
name. You can edit this file using the
Admin Tool. Click the
Network Settings tab and click Edit Hosts File. See also “The
HOSTS File,” page 1-26.
ras.properties Used to both configure modems and enable the direct dial function.
See “About the ras.properties File,” page 4-12.
ddns.properties Used to configure properties of the TZO DDNS service. See “About
the ddns.properties file,” page 5-23.
net.properties Contains DNS configuration properties (this platform only) as set
with the Admin Tool (
Network Settings tab). Parameters of special
note used in communications:
• domainName—DNS domain in which the JACE resides
• dnsServerList—list of DNS server IP addresses
• defaultGateway—IP address of default gateway
drivers.properties <release>\nre\lib\ Used to implement and configure various drivers. You can edit this
file using the Admin Tool (Installation tab). Typically you do not
need to edit this file unless configuring a specific driver (follow
instructions in the integration document). Parameters of special note
used in communications on this platform:
• comm.driverClass—provides access to the serial ports. The
driverClass property is platform specific and must be present. You
should never modify it.
• comm.enumPorts—when set to true will list available serial ports
in the Standard Output window of the station on startup.
niagarad.properties Used to configure niagarad, the Admin Tool interface to the OS.†
Also used to change the default port you use to connect to the host
with the Admin Tool. Must be edited with a text editor (not through
the Admin Tool). See also “Changing the Administration Port
(3011),” page 6-12.
