While looking for an evasive SIP Gateway related problem I used wireshark to collect additional traffic. Unfortunatly once I had taken the wirshark capture file (which had grown to almost 2 GB) to my laptop for analyzing I found that it lacked sufficient memory to load this enormous capture file.
I found that wirshark shipped with tools that have the ability to split the capture to a manageable size. How does it work?
You can split the capture file as follows:-
3. This will give you the number of packets in the trace so can decide how to split the file. Only 290 packets in my screenshot 🙂

5. You will now have as many files as required to complete the split, they will be called what you stated as the dest file above followed by -0000, -0001 etc
