I have attended multiple Wireshark webinars presented by Riverbed and leaders in the field. They title this series “Return to the Packet Trenches” with some sort of variation or subtitle for the different sessions. I always walk away with something new. This latest webinar was no exception. It reviewed several CLI options for creating, analyzing, and editing packet captures. I highly recommend attending these webinars if you have any interest in Wireshark and staring at packets.
Using file sets in Wireshark is a great feature. It allows for quickly navigating between smaller files instead of experiencing sluggish performance when analyzing one large file. However, there are times when packet captures were taken using a system other than Wireshark (such as TCPDump or Dumpcap). Other times someone else performs the captures and uses a different naming convention. Either way, there are times when it would be nice to convert these names into Wireshark’s file set naming convention.
