Practical Packet Analysis, 3E: Using Wireshark to Solve Real-World Network Problems

It's easy to capture packets with Wireshark, the world's most popular network sniffer, whether off the wire or from the air. But how do you use those packets to understand what's happening on your network? Updated to cover Wireshark 2.x, the third edition of __Practical Packet Analysis__ will teach you to make sense of your packet captures so that you can better troubleshoot network problems. You'll find added coverage of IPv6 and SMTP, a new chapter on the powerful command line packet analyzers tcpdump and TShark, and an appendix on how to read and reference packet values using a packet map. __Practical Packet Analysis__ will show you how to: -Monitor your network in real time and tap live network communications -Build customized capture and display filters -Use packet analysis to troubleshoot and resolve common network problems, like loss of connectivity, DNS issues, and slow speeds -Explore modern exploits and malware at the packet level -Extract files sent across a network from packet captures -Graph traffic patterns to visualize the data flowing across your network -Use advanced Wireshark features to understand confusing captures -Build statistics and reports to help you better explain technical network information to non-techies No matter what your level of experience is, __Practical Packet Analysis__ will show you how to use Wireshark to make sense of any network and get things done. It's easy enough to install Wireshark and begin capturing packets off the wire--or from the air. But how do you interpret those packets once you've captured them? And how can those packets help you to better understand what's going on under the hood of your network? Practical Packet Analysis shows how to use Wireshark to capture and then analyze packets as you take an indepth look at real-world packet analysis and network troubleshooting. The way the pros do it. Wireshark (derived from the Ethereal project), has become the world's most popular network sniffing application. But while Wireshark comes with documentation, there's not a whole lot of information to show you how to use it in real-world scenarios. Practical Packet Analysis shows you how Because net-centric computing requires a deep understanding of network communication at the packet level, Practical Packet Analysis is a must have for any network technician, administrator, or engineer troubleshooting network problems of any kind.
