Chapter 18: Subsetting, Saving, and Exporting Captures
Not every packet capture is the perfect size or representative of the data you need to analyze. Whether you have captured the traffic yourself or someone has sent a file to you to examine, some packet captures are large and cumbersome. Many times, large files have to be subdivided into smaller files for effective analysis. In addition, when done, you will most likely need to save the file, or in some cases, export the capture into a specific format.
In this chapter, we'll cover several methods and techniques that we can use to work with packet captures. So that you can reduce a large file to a more manageable size, we'll look at filtering the capture to narrow down the results. You'll learn how versatile Wireshark is in exporting different components of a capture. Finally, you'll see how you can export files, along with specified packets, packet dissections, and objects. In addition, you'll discover...
