1 00:00:00,000 --> 00:00:08,275 2 00:00:08,275 --> 00:00:10,786 So when you consider selecting an interface 3 00:00:10,786 --> 00:00:12,644 one of the important things to do is to know 4 00:00:12,645 --> 00:00:15,115 what interfaces you actually have configured. 5 00:00:15,126 --> 00:00:18,003 And by doing that you could find that on 6 00:00:17,996 --> 00:00:20,160 the main launchpad. 7 00:00:20,173 --> 00:00:23,072 On this start page, you're going to see 8 00:00:23,064 --> 00:00:26,446 specifically what interfaces 9 00:00:26,439 --> 00:00:28,869 are loaded on the host machine 10 00:00:28,862 --> 00:00:31,352 and what you can do to customize them 11 00:00:31,352 --> 00:00:33,041 before you use them. 12 00:00:33,041 --> 00:00:34,520 And this is what the key is, right? 13 00:00:34,512 --> 00:00:37,025 So, what are you going to do 14 00:00:37,018 --> 00:00:38,734 to actually modify an interface? 15 00:00:38,734 --> 00:00:41,029 Well, when you're modifying an interface 16 00:00:41,029 --> 00:00:44,299 we're not necessarily going in and adjusting 17 00:00:44,299 --> 00:00:47,854 you know, the duplex or we're not, you know, 18 00:00:47,854 --> 00:00:49,799 changing the speed or anything like that. 19 00:00:49,799 --> 00:00:52,713 What we're doing is we're setting up how 20 00:00:52,722 --> 00:00:56,456 Wireshark inter-operates with the interface. 21 00:00:56,455 --> 00:01:01,124 So, what that allows you to do is to, 22 00:01:01,132 --> 00:01:03,132 you know, add a filter, 23 00:01:03,140 --> 00:01:05,362 you can break up your files, 24 00:01:05,376 --> 00:01:07,528 your segments, inter-segments. 25 00:01:07,549 --> 00:01:10,071 You can tune new capture, 26 00:01:10,071 --> 00:01:11,920 you can time your capture. 27 00:01:11,920 --> 00:01:13,920 And you can limit the size of each capture. 28 00:01:13,920 --> 00:01:17,724 So when you go into select, 29 00:01:17,733 --> 00:01:19,208 just remember that you select 30 00:01:19,208 --> 00:01:21,114 the interface that you want to adjust 31 00:01:21,114 --> 00:01:25,961 and then you change your capture options. 32 00:01:25,961 --> 00:01:27,730 Then you can modify the launch pad. 33 00:01:27,739 --> 00:01:29,691 You can hide anything that you 34 00:01:29,682 --> 00:01:30,852 it is that you don't want to see 35 00:01:30,852 --> 00:01:32,424 as far as interfaces go. 36 00:01:32,424 --> 00:01:35,730 There'll be many time at least in my machine, 37 00:01:35,739 --> 00:01:39,887 I tend to have at least 10 or more interfaces. 38 00:01:39,887 --> 00:01:42,857 When I want to go in and use Wireshark quickly, 39 00:01:42,857 --> 00:01:45,584 the last thing I want to do is to have to go in, 40 00:01:45,582 --> 00:01:47,821 find what interface it is that I want to use. 41 00:01:47,817 --> 00:01:49,606 There's certain things that I don't need 42 00:01:49,606 --> 00:01:51,629 Wireshark to show me so I'm going to 43 00:01:51,628 --> 00:01:54,331 go in and I'm going to take those out. 44 00:01:54,331 --> 00:01:56,607 Those, you will not see those, and 45 00:01:56,606 --> 00:01:59,068 by doing so, it's going to allow 46 00:01:59,065 --> 00:02:03,187 for less confusion and quicker monitoring 47 00:02:03,187 --> 00:02:07,375 of the traffic coming through the network. 48 00:02:07,375 --> 00:02:09,534 And to do that is when you go in 49 00:02:09,541 --> 00:02:11,581 to the interfaces themselves. 50 00:02:11,595 --> 00:02:13,260 You can choose to hide them. 51 00:02:13,272 --> 00:02:16,031 So, in the graphic that I have up now, 52 00:02:16,042 --> 00:02:17,898 you can select specifically, 53 00:02:17,901 --> 00:02:20,438 ok, I don't really need to see 54 00:02:20,430 --> 00:02:22,731 my bluetooth network connection. 55 00:02:22,731 --> 00:02:24,827 So everytime I open up the launch pad 56 00:02:24,842 --> 00:02:26,771 I want to hide that. I want to make sure that 57 00:02:26,772 --> 00:02:29,458 that goes away and when I open up 58 00:02:29,479 --> 00:02:31,460 I do not see that. I'm presented with 59 00:02:31,465 --> 00:02:33,672 specifically, either my LAN 60 00:02:33,687 --> 00:02:35,489 or my wireless LAN connection 61 00:02:35,513 --> 00:02:37,666 and I'm good to go. By doing that, 62 00:02:37,666 --> 00:02:39,437 again it avoids confusion. 63 00:02:39,437 --> 00:02:43,045 It allows me to use the tool more effectively. 64 00:02:43,045 --> 00:02:44,682 It lets me get in and do what it is 65 00:02:44,682 --> 00:02:46,308 that I need to do quickly. 66 00:02:46,308 --> 00:02:50,107 And then, I can also look at 67 00:02:50,107 --> 00:02:52,023 the actual interfaces themselves 68 00:02:52,023 --> 00:02:54,337 which is going to tell me a lot of information. 69 00:02:54,337 --> 00:02:56,936 It's going to tell the status and the speed 70 00:02:56,933 --> 00:03:00,080 of the interface which can be helpful. 71 00:03:00,100 --> 00:03:03,483 So, for example, if I know that I'm having 72 00:03:03,480 --> 00:03:07,168 a performance issue, I would likely or 73 00:03:07,173 --> 00:03:10,816 would hope to be on a gigabit connection. 74 00:03:10,816 --> 00:03:12,244 So I would be able to check that. 75 00:03:12,253 --> 00:03:13,448 I will be able to see the amount 76 00:03:13,448 --> 00:03:15,052 of packets coming in and out. 77 00:03:15,052 --> 00:03:18,870 I will be able to see VLAN information, 78 00:03:18,870 --> 00:03:22,071 the packet count, that is 79 00:03:22,071 --> 00:03:24,251 when I run the capture, how many 80 00:03:24,253 --> 00:03:28,026 packets are being counted or captured. 81 00:03:28,026 --> 00:03:32,278 And I'll be able to see errors on the interface. 82 00:03:32,278 --> 00:03:34,835 And I'll be able to look at the MAC 83 00:03:34,842 --> 00:03:37,010 and the IP information. 84 00:03:37,001 --> 00:03:39,001 Why is this important? 85 00:03:39,009 --> 00:03:42,071 This is important because when you go 86 00:03:42,071 --> 00:03:44,000 into Wireshark to run your capture, 87 00:03:44,000 --> 00:03:47,143 the most relevant information 88 00:03:47,143 --> 00:03:48,899 is what you want to see. 89 00:03:48,899 --> 00:03:51,584 You want to consolidate what it is that 90 00:03:51,586 --> 00:03:52,948 you don't want to see or remove it 91 00:03:52,940 --> 00:03:55,273 completety so that you do not 92 00:03:55,281 --> 00:03:58,420 get confused coming in and by doing so 93 00:03:58,431 --> 00:04:00,244 you customized your launch pad. 94 00:04:00,244 --> 00:04:02,142 You use policies and profiles 95 00:04:02,134 --> 00:04:04,225 to customize everything so you can 96 00:04:04,232 --> 00:04:05,748 come in quickly and you can 97 00:04:05,744 --> 00:04:08,015 troubleshoot your problem. 98 00:04:08,026 --> 00:04:12,987
