If ‘Allow sub-dissector to reassemble TCP streams’ is on and the HTTP reassembly preferences have been left at their defaults (on), http.time will be the time between the GET request and the last packet of the response.
If the TCP preference ‘Allow sub-dissector to reassemble TCP streams’ is off, the http.time will be the time between the GET request and the first packet of the response, the one containing ‘OK’.
Go to Protocol preference and then uncheck the sub-dissector to reassemble TCP streams (marked and shown in Figure 3). Step 4: In order to view the response of HTTP, right-click on any response packet (HTTP/1.1). Syntax: ip.addr= 91.198.174.192 & ip.addr = 192.168.155.59 Figure 3: Allow sub-dissector to reassemble TCP streams Figure 4: Response time Start filtering the IP of (a simple traceroute or pathping can reveal the IP address of any Web server) and your local PC IP (a simple ipconfig for Windows and ifconfig for Linux can reveal your local PC IP). Step 3: We now filter the requests and response sent from the local PC to Wikipedia and vice versa. Now filter all the HTTP packets as shown in Figure 2, as follows: syntax: http ‘200 OK’ implies that the response contains a payload, which represents the status of the requested resource (the request is successful). Step 2: Here, we make a request to and, as a result, Wikipedia sends an HTTP response of ‘200 OK’, which indicates the requested action was successful. Figure 1: Interface selection Figure 2: Filtering HTTP Refer to the bounding box in Figure 1 for available interfaces. Step 1: Start capturing the packets using Wireshark on a specified interface to which you are connected.
