The redirect is done with the HTTP response code 302. But we do know its to an HTTP address, so we may assume the server TCP port used is 80. The "Filter Expression" dialog box can help you build display filters. The redirect must point to a HTTPS address Since the filter has to hit on the response, we have no access to the original request. For display filters, try the display filters page on the Wireshark wiki. For example, to capture only packets sent to port 80, use: dst tcp port 80Ĭouple that with an http display filter, or use: tcp.dstport = 80 & httpįor more on capture filters, read " Filtering while capturing" from the Wireshark user guide, the capture filters page on the Wireshark wiki, or pcap-filter (7) man page.

If you want to measure the number of connections rather than the amount of data, you can limit the capture or display filters to one side of the communication. This one filters all HTTP GET and POST requests. Note that a filter of http is not equivalent to the other two, which will include handshake and termination packets. Wireshark HTTP Method Filter If you want to dig into your HTTP traffic you can filter for things like GET, PUT, POST, DELETE, HEAD, OPTIONS, CONNECT, and TRACE. Next we will analyze the SSL packets and answer a few questions 1. Filter the captured packets by ssl and hit Apply: Now we should be only looking at SSL packets. Ping packets should use an ICMP type of 8 (echo) or 0 (echo reply), so you could use a capture filter of: icmpĪnd a display filter of: icmp.type = 8 || icmp.type = 0įor HTTP, you can use a capture filter of: tcp port 80 Wireshark capture: Depending on your network, you could have just captured MANY packets.
