Table A-1 lists files used in communications on VxWorks-based Niagara hosts.
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.
system.properties Used to configure properties of the system (host). For this
platform, you can only edit using a text editor (not through the
Admin Tool). Parameters of special note used in
communications on this platform:
• resolveIpAddresses—when true, indicates whether the
system should resolve IP addresses of incoming
communications to host names before allowing connection.
Default is false.
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.
ddns.properties Used to configure properties of the TZO DDNS service. Typically
not used on this platform.
ipchanges.txt <release>\nre\user Lists any IP address change that you make with the Admin Tool.
See “About the ipchanges.txt file,” page 3-16.
