Hello, I am using cashark to analyze the EPICS network, and I encountered a problem.I use ca.lua and pva.lua in the same way. Wireshark has no problem when using the ca plug-in, but it will report an error when using the pva plug-in. According to the error message, how can I specify the TCP and UDP ports when I start wireshark with pva.lua? Snipaste_2021-12-27_19-27-12 Thanks for your help!

Which version of wireshark are you running?

https://github.com/mdavidsaver/cashark/blob/6448936200e7bf47a7da29138933e205ae567c64/pva.lua#L330-L334

I've seen registration succeed with wireshark >= 2.6

... how can I specify the TCP and UDP ports when I start wireshark with pva.lua?

See 11.4.2. User Specified Decodes
