Each of the exercises below is similar to an end-of-chapter problem in the text. Most importantly, you can keep generating new instances of each exercise (and hopefully solving each one!) until you've mastered the material. You may be interested in other supplemental material (online lectures, powerpoint slides, review questions, Wireshark labs) for our book, available here. This page replaces the earlier interactive problems page, and includes a number of new problems. We're actively adding new problems here.
