SharkFest'24 US

The Packet Doctors are in! Packet trace examinations with the experts
06-19, 14:00–15:30 (America/New_York), Potomac Ballroom

The experts on this panel have been asked to look at a trace file and help find a reason for certain behaviors by attendees at many SharkFests. Based on this, they’ve decided to create a public forum for examining individual trace files with a broader audience for a collective learning experience. Trace files will be gathered from attendees prior to SharkFest and only given to the panel members during the session so that the “not-knowing what to expect and whether it can be solved” experience of working through an unknown trace file can be preserved.

Come to this session and learn to ask the right questions and look at packets in different ways.
