Open TCP Port 1037 on CompactRIO 9076 Controller

[wolframk]

We running a LAbVIEW application software on the CompactRIO NI 9076 System  under , LabVIEW 2014. Now we have discovered that there is an open TCP Port Number 1037. Does anybody know what this port is for and how can we disbale this.

All known ports like Visa, or execution trace toolkit use other ports..

Our IT security has found this open port...

Hello, 

Could you please describe what your code is doing? 

And also take a look on this, it may give you some ideas.

The LabVIEW code just runs a measurement application on the Compact RIO, nothing special. We just did run a port scanner and couldn t find a hint who is opening that port. Its not in the LabVIEW Source code... Coudl be any kind of sevice from VxWorks ? We have checked for VISA, but thats another port

Hi,

Well I believe this is something related to firewall, but I'm not sure what could be the source for your code.

TCP port 1037 is likely for a service on VxWorks controllers providing HW enumeration for MAX. If so, here's additional information you might find helpful:

• It uses a dynamic port, usually found in the range of 1030-1050. The port is not configurable but can be disabled. (Read on.)
• The service port mapping will be reported by the NI Service Locator on the controller if you query it like so: http://HostnameOrIpAddress:3580/dumpinfo?
• The service gets installed with just about any NI driver, including NI-VISA.
• How to prevent the port from being opened: Install the NI System Configuration Remote Support feature to the controller. This will cause the same remote functionality to be served up over http instead.
