WEBVTT 00:00.480 --> 00:09.870 In this video, we are going to learn how to configure and choose the correct network interface or interfaces 00:09.870 --> 00:12.320 to capture the packets. 00:12.360 --> 00:14.700 So open your Wireshark. 00:14.730 --> 00:18.390 This is the welcome window of Wireshark. 00:18.420 --> 00:23.670 It displays all the installed network interface cards. 00:23.700 --> 00:29.730 Now, this list of interfaces is going to be different for everyone. 00:29.790 --> 00:36.270 Most probably you are not going to see all these local area connections that I have here. 00:36.300 --> 00:40.860 They are not real or physical network cards. 00:40.980 --> 00:46.710 They are created by my portable modems and virtual machines. 00:46.860 --> 00:55.260 Now there are minimum to real or physical network cards on each system. 00:55.260 --> 01:04.860 Wireless card and Ethernet wireless card is represented by wi fi on Windows, and Ethernet is simply 01:04.860 --> 01:08.610 represented by Ethernet on Linux. 01:08.640 --> 01:20.020 The wireless card is represented by W LAN zero and Ethernet is represented by it o or and as a33. 01:20.040 --> 01:29.790 Now to start capturing the packets, you have to select the network interface that you are using to 01:29.820 --> 01:34.540 connect or access your network or Internet. 01:34.560 --> 01:41.670 I am connected to my network through a wireless card, so I am going to select the wi fi. 01:41.820 --> 01:46.320 As you can see, the wi fi interface has spikes, right? 01:46.350 --> 01:53.540 These spikes indicate that this interface is sending and receiving packets. 01:53.550 --> 01:54.690 It is active. 01:54.930 --> 02:00.690 We also have spikes in the adapter for loopback traffic capture. 02:00.710 --> 02:01.350 Right. 02:01.440 --> 02:04.440 Basically, this is your local host. 02:04.770 --> 02:08.340 It does not capture your network's traffic. 02:08.370 --> 02:12.960 It just monitors traffic within your own system. 02:13.260 --> 02:21.660 Again, I am connected to my network through wireless card, so I'm going to select the wi fi to start 02:21.660 --> 02:23.370 capturing the packets. 02:23.520 --> 02:31.770 So double click on wi fi or the appropriate interface that you are using to access your network. 02:31.770 --> 02:34.100 So double click on the interface. 02:34.110 --> 02:40.740 As you can see, there is Wireshark is capturing packets on wi fi right now. 02:40.800 --> 02:47.370 Wireshark allows you to capture packets on multiple interfaces as well. 02:47.370 --> 02:50.100 So let me close the current session. 02:50.100 --> 02:51.540 Click on Red Button. 02:51.540 --> 02:57.720 Now click on this close button to go back to Welcome Window, continue without saving. 02:57.750 --> 03:04.440 Now press and hold the control button, then select the interfaces. 03:04.440 --> 03:09.720 So I'm going to select wi fi and adapter for loop back capture. 03:09.720 --> 03:17.640 When you select multiple interfaces, then to start capturing the packets, you have to click on the 03:17.640 --> 03:21.810 first button in the main toolbar, click on the button. 03:21.810 --> 03:29.250 Now, as you can see, Wireshark has started to capture packets on the selected interfaces. 03:29.310 --> 03:34.470 Right now, let's clean the welcome window right here. 03:34.470 --> 03:37.800 We have a lot of unnecessary interfaces. 03:37.830 --> 03:40.770 Most of them will never be used. 03:40.980 --> 03:48.090 So to remove the interfaces on your right side, click on the down arrow. 03:48.180 --> 03:55.470 If you want to hide all the wired interfaces, then click on the wild. 03:55.470 --> 04:01.920 Now as you can see, the wired interfaces have been removed from the list, right? 04:01.920 --> 04:10.620 And this way you can remove or keep other interfaces like wireless or virtual interfaces. 04:10.650 --> 04:14.970 Just click on it to remove and display. 04:15.000 --> 04:22.710 Right now, guys, this list does not give us option to select interfaces manually. 04:22.710 --> 04:23.340 Right? 04:23.370 --> 04:31.200 I only want to keep two interfaces on my welcome window wi fi and ethernet. 04:31.200 --> 04:35.520 With this option we can either have wireless or wired. 04:35.730 --> 04:39.450 So to customize this list, go to the CAPTCHA. 04:39.480 --> 04:44.490 Click on options on your bottom right click on Manage Interfaces. 04:44.520 --> 04:48.510 Now here we have a complete list of interfaces. 04:48.510 --> 04:56.430 Here we can select the interfaces that we do not want to see on your welcome window. 04:56.430 --> 04:59.940 So I'm going to deselect all the interfaces except. 05:00.110 --> 05:01.970 Ethernet and WiFi. 05:02.360 --> 05:04.730 Now click on okay close. 05:04.760 --> 05:12.110 As you can see, guys, now we only have WiFi and Ethernet, but we have these unnecessary captions, 05:12.110 --> 05:12.510 right? 05:12.530 --> 05:16.760 Microsoft WiFi Ethernet connection 1218 Ethernet. 05:16.760 --> 05:17.240 Right. 05:17.240 --> 05:23.660 So when you customize the interfaces, it adds these unnecessary comments. 05:23.660 --> 05:31.280 So to remove unnecessary comments, again, go to the CAPTCHA options, click on manage interfaces under 05:31.280 --> 05:34.550 the comment column, double click on the interface. 05:34.550 --> 05:36.320 I'm going to click on wi fi. 05:36.350 --> 05:40.820 Now leave this field blank press enter again. 05:40.820 --> 05:44.810 I'm going to repeat the same thing for Ethernet interface. 05:44.870 --> 05:45.890 Double click on it. 05:45.920 --> 05:47.310 Leave it blank. 05:47.330 --> 05:48.410 Press enter. 05:48.410 --> 05:49.250 Click on. 05:49.250 --> 05:51.120 Okay, close. 05:51.140 --> 05:57.350 Now, as you can see, guys, we have a very neat and clean list of interfaces.
