Summary

 < Day Day Up > 



In this chapter you have learned the major components of the Ethereal GUI. You have also learned the major functionality of the Ethereal application and how to access it.

You should now be able to perform network captures, open saved network captures, and print captures. You are also equipped to use display filters to filter the packets displayed in the Summary Window, color the packets in the Summary Window for easier readability, or find a packet in the capture with particular characteristics.

We’ve shown how to navigate the protocol tree in the Protocol Tree Window to drill down into the contents of a packet, and use the protocol tree fields to prepare new display filter strings.

Finally, you now know how to force a packet or group of packets to be decoded by a particular dissector. You have learned how to enable and disable decoding of particular protocols, and should have some understanding of how to use some of the more commonly used tools in Ethereal to gain better visibility into TCP Streams.
