WOW,

Thank you for the fast respond. I really appreciate it.

I do have a follow up question (sorry for being greedy). After dividing the 500MB packet capture I just realized that I have only 15minutes of traffic and I actually need a specific traffic from the packet capture.  Let’s say I want to filter only traffic that has destination UDP port of 9000. Is it possible to do something like this from command line? Or do I need to open the GUI for it? (I was actually able to open the packet capture after you showed me how to divide the files… but if its possible to divide the file using a specific network/wireshark filter it would be great).

Hi Boaz,

You can use editcap:

http://www.wireshark.org/docs/man-pages/editcap.html

Use capinfos to see how many packets the 500MB file contains:

http://www.wireshark.org/docs/man-pages/capinfos.html

$ capinfos -eac test.pcap
File name: test.pcap
Number of packets: 293054
Start time: Thu Oct 02 10:38:49 2008
End time: Thu Oct 02 12:11:23 2008


Next use editcap to split the file:
editcap <option -c packets per file> infile outfile
$ editcap -c 60000 test.pcap split.pcap


This is the result:
$ capinfos -c split*
File name: split.pcap-00000
Number of packets: 60000

File name: split.pcap-00001
Number of packets: 60000

File name: split.pcap-00002
Number of packets: 60000

File name: split.pcap-00003
Number of packets: 60000

File name: split.pcap-00004
Number of packets: 53054

Hope this helps
Joan
