Is it possible in Wireshark to highlight or color sip header based on filter? Example.. Filter- sip.reason Wireshark shows packets which contains reason header. I would like to have header highlighted so that is easily identifiable.

If this feature is not there by default then can it be added by some lua scripts?

Example.. Filter- sip.reason Wireshark shows packets which contains reason header. I would like to have header highlighted so that is easily identifiable.

So, if there's a display filter active, you want whatever entries in the packet details refer to a field in the filter expression that causes the packet to match to be highlighted with a different color? So:

  • sip.reason - color all instances of sip.reason
  • sip.reason == XXX - color all instances of sip.reason that have the value XXX

It gets more complicated for filters that involve "and", "or", and "not" operators.

There is currently no mechanism to support that, and that includes "no mechanism available to a Lua script to do that". You should file an enhancement request as an issue in the Wireshark issues list.

Not the solution for your reuqest, but maybe a good workaround, if you search for a string in the packet-details, the string will get highlighted. So after the filtering, you could use the find function to specifically highlight the parts of the packet that you are looking for (assuming there is a string or regex filter possible for what you need to locate).

I tried your suggestion but find didn't highlight the element of the tree. It only shows me the packet.

This not what I am looking for. I want to color one or more elements of the sip subtree

It is not possible to colour individual items in the tree.

Can it be done by lua script?
