Looking to see if there are any options for running a UDP sniffer tool that looks at all ethernet traffic on the wire, similar to NpCap on windows? The last time this question was asked to the community was 2014 and it seems the answer then was "there is no standardazed PCap option for any of them, for the first two because nobody has developed it..." Now that NI Linux RT has been more fully developed and available across the product range, looking to see if any new solutions exist? The problem we are trying to solve is that we have UDP network traffic on a cRIO ethernet port that we need to inspect and parse, however the destination IP address and port are not that of the cRIO. They are destined for other hardware on the network. This is being integrated into a legacy hardware system that uses an old network hub, and that hardware must currently be maintained as-is. Ideally, we would then be able to access these functions/libraries within a model or custom device in an NI VeriStand environment on the cRIO (but that is the next step).

Labview RT Ethernet Sniffer (2021 Update?)

Hi Christophe,

Did you ever get this to work? Do you have any details you can share on how to generate the wrapper library calls for LabVIEW (Or even better the VIs you used😁). I am trying to run this on Linux-x64 RT system also.
