Configuration: Script Management > Auto Configuration
Auto Config lets you perform an auto-configuration via a URL script file. It is typically used
for remote configuration and troubleshooting or to configure VBrick appliances that are
behind a firewall. To configure a parameter on an appliance (or more likely a set of
parameters) you simply point the URL to a server with an .xml configuration file. This is
useful, for example, to change a reflector URL, set the audio and video rates, etc. when the
VBrick appliances are behind a firewall and cannot be accessed remotely.
The VBrick reads the URL field (e.g.
www.myserver.com/config.xml
) via HTTP protocol and
executes the script depending on the
VBEXECUTE
tag. If a
VBEXECUTEFORCE
tag is present in
the .xml file (see example below), the script runs every time at the poll interval even if it has
not changed. If a
VBEXECUTEIFDIF
tag is present the script runs only if it is different from the
last executed file. One of these tags is required.
If the VBrick is in
Edit
mode, the script file will not run until the edit session is ended. The
auto config script will run before any waiting IR scripts or external event scripts. In
Edit
mode, you can press
Run Script
to execute the script on demand. After a reboot, the VBrick
checks for a script URL and will run the script immediately, regardless of the
VBEXECUTE
tag
value.
