Apparently there is a way in Ubuntu, but I'm on a Windows box. XP, to be specific. I want to import this data into Access, but can't figure out how to even open the file and Access won't recognize the extension.

Does anyone know how to open one of these files, or convert it to something Access understands?

Here's the Ubuntu link:


  • Maybe this leads you somewhere wireshark.org/lists/wireshark-users/200804/msg00270.html. BTW I got that through Google

  • Was there information on how to open a .dump file from Windows at that link? Because I didn't see any. Commented Aug 19, 2015 at 13:05
  • Johnny, the extension .dump can stand for many things – it's neither bound to an application nor to a media type. Can you please edit your question and include what kind of file that is (what was it created by, and what it's supposed to contain)? // Just seeing your answer: Yes, MySQL is one example. It could well have been some binary dump from some other app :)

  • If a .dump file is not specific to WireShark, then the guy who edited my question should roll it back. Commented Aug 19, 2015 at 21:33

You could use scapy which will read a pcap file and will even write them, (it will also allow you to capture traffic without wireshark and generate traffic which wireshark will not do).

Example of reading from the demo:

>>> a=rdpcap("/spare/captures/isakmp.cap")
>>> a
<isakmp.cap: UDP:721 TCP:0 ICMP:0 Other:0>
>>> a[423].pdfdump(layer_shift=1)
>>> a[423].psdump("/tmp/isakmp_pkt.eps",layer_shift=1)

enter image description here


I believe Wireshark dump files are pcap files.

A couple of options:

  • Open them using tcpdump which produces text output, which you could parse in Access code.
  • Read them using a library such as pcap.net, which I think you can use from Access.

VEdit will open files with a .dump extension. Turns out the files in question are simple ASCII and look like MySQL code to recreate tables of data, complete with table layouts and insert statements. I'll have to see whether or not I can import them into MySQL or if they need to be converted first.
