parsing - How to validate a message in pcap? -


i have requirement expand required tree in decoded parameters of pcap file , validate message in it.

example: open "transmission control protocol" shown in screenshot , and validate message "this ack segment in frame: 278".

need develop automation script in java validating messages in pcap files . using jnetpcap lib. appreciate inputs!. enter image description here

you can't, without protocol analysis yourself. pcap file doesn't include such massages.

the message "this ack segment in frame: 278" generated wireshark after tcp session analysis itself. frame number 278 assigned wireshark. pcap file contains packets' data.
