We use the duration keyword in place of filesize to specify a length of time (in seconds) to spend filling each file (for example, one hour, or 3600 seconds). To explicitly specify the PATH, you may need to include the path portion in double quotes (e.g. In order for the system to find dumpcap, you will need to include it as part of the Windows PATH environment variable, or explicitly specify the path. It resides in the Wireshark root folder (e.g. To capture Wireshark data, you will need to use “dumpcap” which is a command line utility installed as part of Wireshark. I answered question 5 correctly so I think I'm on the right track and I've done all the other Wireshark labs with similar filters and haven't had any problems with percentages.How to use Wireshark (on Windows) to capture a driver or network issue that may only occur very infrequently, for example, to capture data on an issue which may occur only once a month. I've tried other variations too, total packets 10594 and displayed is 86 so i've tried. I used the filter (http.request or = 1 or tcp.flags eq 0x0002) and !(tcp.port eq 25)Ĩ% is displayed in the bottom right but it won't accept my answer. What percentage of results are then displayed in the capture? Now take the filter used in the previous question, and add an OR expression which filters by (.tcp flags equal to 0x0002) and a further expression which filters by packets NOT from (tcp port 25). I've tried other variations too, total packets 10594 and displayed is 37 so i've tried. I used the filter (http.request or = 1) stated in the question itself and 3% is displayed in the bottom right but it won't accept my answer. From the PCAP provided, apply a filter to display all web traffic (http.request or = 1). I cannot get the answer to questions 3 or 5 and I don't know what I'm doing wrong.ģ.
