Display filters let you compare the fields within a protocol against a.
If a packet meets the requirements expressed in your filter, then it is displayed in the list of packets. The output could now be used to pipe it to netcat (or directly send it from perl). Wireshark and TShark share a powerful filter engine that helps remove the noise from a packet trace and lets you see only the packets that interest you. Will read packets from the file "/tmp/tcp80", and print the HTTP requests. This module will not only reassemble the TCP streams, it will also extract HTTP requests: Load kerberos crypto keys from the specified. The probably easiest way to parse the packet capture, and extract the request, is the perl module "Sniffer::HTTP". Lower-level protocols must be explicitly specified in the filter. You can only extract individual headers easily or the URLs. Following flow logs the bodies in the 3 available. "tshark" does not have a simple feature to just extract the http requests. Select the data type (JSON object, UTF8-string, Buffer) of both the request body and the response body. "wireshark" can be used to extract the data using the tcp stream reassembly feature, but this can't easily be scripted. "tcpreplay" may appear like the right tool, but it will just blindly replay the traffic, and the web server will not actually establish a connection. sending the packet capture to a web server extracting the HTTP requests from the packet capture. However, I am sometimes faced with a different problem: You do have a network capture of a set of HTTP requests, and you are trying to "replay" them in all of their beauty, which includes all headers and POST data if present. For example Jim Clausing's brilliant perl script, or the Wireshark "export features among many others (chaosreader, xplico, network miner. There are plenty of tools to extract files that are transmitted via HTTP.
