tcpdump instead IOtrace

[Y3G]

Hi,

I am running under a docker and cannot install any NI-Visa I/O
On my PC I have NI-tools and locally can verify the VSA exchange between SW and Instrument, but not on the Docker....
The only tool available is the tcpdump and analyzing it on Wireshark.
Does anyone used it before/ know the filter to apply or has any solution how to see VISA-488.2 traffic on a docker?
Thanks in advance

That makes it tough, because, all the VISA and 488.2 traffic go through the VISA driver layer which could well be a propreitary low level register communication with NI GPIB hardware or serial IO through the OS - these could not be caught by tcpdump I guess going by the name.

You may be lucky to catch LXI traffic but I guess not the traditional GPIB, Serial or USB traffic.
