I can see three SYN packets to google. (Note: If you are unable to run Wireshark on a live network connection, you can use the http-ethereal-trace-4 packet trace to answer the questions below see footnote 1. Server then attempts to make a connection directly to iii. The following will explain capturing on 802.11 wireless networks ().If you are only trying to capture network traffic between the machine running Wireshark or TShark and other machines on the network, are only interested in regular network data, rather than 802. Stop Wireshark packet capture, and enter http in the display-filter-specification window, so that only captured HTTP messages will be displayed. All traffic related to then via the web proxy HAR (HTTP Archive) is a file format used by several HTTP session tools to export the captured data. I then set the proxy, and ran a Wireshark trace whilst attempting to browse to CAPTURE_B In TCP, once the connection is established, all packets sent by either side will contain an ACK, even if its just re-acknowledging data that its already acknowledged. Without the proxy set in IE, I ran a Wireshark whilst attempting to browse to CAPTURE_A PSH,ACK wireshark capture 2 Answers: 2 ACK means that the machine sending the packet with ACK is acknowledging data that it had received from the other machine. In our organisation, we have an HTTP proxy for web traffic: that operates on port 8080. Once configured, we can start the capture in Wireshark and start receiving packets.
