how to edit wireshark pcap to change the order of packets

i have a pcap file captured using wireshark. suppose the pcap has 6 packets numbered from 1 to 6 as shown below. now i want to edit this pcap file so that i get the packets in some different order. For eg, if original pcap packets are 

1,2,3,4,5,6

i want a new pcap after editing, where now packets are in the order (say for example) as :

2,3,1,4,5,6

similarly i can have some other order for eg, 2,4,5,6,1,3 or any other order.

Can anyone let me know how can i do that ? (may be using wireshark or any other method). any help will be greatly appreciated. thanks

Solution

  • You can use combination of editcap and mergecap

    To solve your problem:

    editcap -r in.pcap tmp1 2-3
editcap -r in.pcap tmp2 1
editcap -r in.pcap tmp3 4-6
mergecap -w out.pcap -a tmp1 tmp2 tmp3
