Wireshark · Wireshark-dev: [Wireshark-dev] Get packet data from previous packet

["Stratemeier, Frank" <FStratemeier@xxxxxxxxx>]

Hi there!

 

I am developing a dissector for a PLC communication protocol which is transported via tcp or udp.

For correct interpretation it is necessary to know the question to a reply, i.e. i need to access the data from one of the previous packets.

 

Is there some mechanism that i can use?

 

find_packet in file.c doesn't really seem to be made for this..

 

 

Any help is appreciated :)
