1 00:00:00,240 --> 00:00:06,420 So have a look at what you see here, there are a lot of packets of Wireshark captures in seconds. 2 00:00:07,230 --> 00:00:13,000 There are some requests and responses for them, broadcasts and their replies and et cetera, et cetera. 3 00:00:13,380 --> 00:00:18,440 There is an easier way to follow a stream, although this is very entertaining. 4 00:00:18,870 --> 00:00:25,170 The Stream is a collection of packets that form a network conversation from the beginning to the end, 5 00:00:25,920 --> 00:00:27,120 just like your favorite story. 6 00:00:28,220 --> 00:00:35,330 So I'm in college now and I captured the traffic just for a little bit, and while I was capturing, 7 00:00:35,330 --> 00:00:38,420 I visited a Web site to create some HTP traffic. 8 00:00:39,380 --> 00:00:48,230 And here are the results, DNS packets, DSP packets, H.T. packets, etc., so I'll select and HDP 9 00:00:48,230 --> 00:00:50,990 packet and it's the get request. 10 00:00:52,070 --> 00:01:00,260 Right, click, go to follow submenu, and here you see the TCP stream and the HTTP stream options are 11 00:01:00,260 --> 00:01:06,300 both enabled, so that means we can follow either the DCP stream or the HTTP stream. 12 00:01:06,680 --> 00:01:08,960 So let's click HTP stream. 13 00:01:10,940 --> 00:01:19,820 Now, the client packets are red and the server packets are blue, they get request by COLLY 200, OK, 14 00:01:19,820 --> 00:01:22,100 response by Oos VW. 15 00:01:23,180 --> 00:01:31,010 Now this is a return page in HTML format, so you can scroll down and we'll see some of the other requests 16 00:01:31,010 --> 00:01:33,410 and the responses and the same stream. 17 00:01:34,470 --> 00:01:40,380 And perhaps you're beginning to see that when you click on a link and website or visit a website by 18 00:01:40,380 --> 00:01:47,180 typing its URL, there might be several consecutive requests and responses that you don't even realize. 19 00:01:47,700 --> 00:01:52,040 But in actuality, you don't need to know them as the end user. 20 00:01:52,200 --> 00:01:56,220 But we're not your typical end users now, are we? 21 00:01:57,000 --> 00:01:58,640 So let's keep going. 22 00:01:59,750 --> 00:02:06,800 From the combo box at the left hand side of the bottom of the stream window, you can filter the conversation 23 00:02:06,800 --> 00:02:10,270 from one side to another or vice versa. 24 00:02:11,230 --> 00:02:19,420 So at the right hand side, right there is another combo box where you can select the output format. 25 00:02:21,410 --> 00:02:27,350 Now, when you close the stream window and go back to the main window of Wireshark, you can see that 26 00:02:27,350 --> 00:02:29,690 the stream filter is applied right here. 27 00:02:29,690 --> 00:02:33,710 So I'll remove the filter by clicking this cross icon. 28 00:02:34,010 --> 00:02:36,820 Now I see the entire captured traffic again. 29 00:02:37,520 --> 00:02:40,160 That is why filters exist.
