1 00:00:03,130 --> 00:00:08,710 Now that we've set up our private host only network, it's time to connect each of our virtual machines 2 00:00:09,070 --> 00:00:10,160 to that V box. 3 00:00:10,210 --> 00:00:11,170 Net zero. 4 00:00:11,530 --> 00:00:13,210 Private virtual network. 5 00:00:13,630 --> 00:00:15,910 So, first of all, we'll do that with Caleigh Linux. 6 00:00:16,330 --> 00:00:22,870 You can change the network settings just by clicking on the network setting in our settings window. 7 00:00:23,320 --> 00:00:28,720 So if we scroll down a little bit, you'll see that network settings tab. 8 00:00:29,320 --> 00:00:30,970 And we can click on network. 9 00:00:31,540 --> 00:00:38,380 And instead of attaching to the mat that that means that my colleague can only see Caleigh itself, 10 00:00:38,380 --> 00:00:39,160 its own machine. 11 00:00:39,490 --> 00:00:43,120 And then out through our host machine into the Internet. 12 00:00:43,510 --> 00:00:45,700 But it can't see any of our virtual machines. 13 00:00:45,700 --> 00:00:50,290 And we want to be able to test hacking and defending across those virtual machines. 14 00:00:50,800 --> 00:00:53,920 So I'm going to come down to the host only adapter. 15 00:00:55,260 --> 00:00:55,500 Feedbacks. 16 00:00:55,930 --> 00:00:56,770 Net zero. 17 00:00:57,280 --> 00:00:57,810 Click, OK. 18 00:01:00,160 --> 00:01:04,700 And I can go ahead and change that network setting for all of my devices at the same time. 19 00:01:05,110 --> 00:01:08,060 I can just click through host only adapter click, OK? 20 00:01:10,060 --> 00:01:11,830 Same thing for the host only adapter. 21 00:01:14,080 --> 00:01:20,890 For our Android device, if you set that up and for the minus floatable to, we'll do the same thing. 22 00:01:22,310 --> 00:01:26,990 In fact, four men hospitable to we really want to stay on a host only adapter, we don't want our meds 23 00:01:26,990 --> 00:01:32,690 political box usually exposed out to the Internet and we'll see why when we hack into that Web server. 24 00:01:34,040 --> 00:01:38,900 So now we need to check to make sure that our IP address is actually showing up correctly, as it turned 25 00:01:38,900 --> 00:01:39,770 out, ODAH three. 26 00:01:39,860 --> 00:01:43,010 So let's open up Kelly Linux and let's start that machine. 27 00:01:44,440 --> 00:01:49,520 You may have to log into your Kelly box again, remember, on newer versions of Kelly, that is KHL 28 00:01:49,570 --> 00:01:51,410 I and KHL I. 29 00:01:51,520 --> 00:01:57,910 Kelly and Kelly for older versions of Kelly, that'll be root and tour T double o r as your username 30 00:01:57,910 --> 00:01:59,310 and password 2020. 31 00:01:59,380 --> 00:01:59,800 A newer. 32 00:01:59,800 --> 00:02:01,000 You've got Kelly and Kelly. 33 00:02:02,420 --> 00:02:04,250 And let's open up a command prompt. 34 00:02:05,730 --> 00:02:13,080 So remember, on our newer Kelly Linux, the command to see the IP addresses, IP and then either HDD 35 00:02:13,140 --> 00:02:21,840 are or just IP, a short for IP address, and you can see Alcalay Linux computer did get a tend out 36 00:02:21,840 --> 00:02:23,870 of three four address. 37 00:02:24,180 --> 00:02:29,280 But there may be times when you're switching networks, especially if you're performing multiple labs 38 00:02:29,280 --> 00:02:36,210 at the same time that you may need to restart the network manager to show you a couple of ways to fix 39 00:02:36,300 --> 00:02:38,700 any IP address problems that might happen in Kalli. 40 00:02:39,120 --> 00:02:45,450 First of all, you can come down to the bottom of your guest machine's window and you can see the network 41 00:02:45,450 --> 00:02:47,430 settings and connect network adapter. 42 00:02:47,970 --> 00:02:51,930 You can actually change your network settings while you're connected to a network. 43 00:02:52,320 --> 00:02:56,010 So if we wanted to change to a different adapter, if we wanted to go back to that, if we wanted to 44 00:02:56,010 --> 00:02:59,250 go to a net network like we'll create in just a moment, we can do that. 45 00:02:59,280 --> 00:03:00,930 But we're on the correct network. 46 00:03:02,190 --> 00:03:04,170 The next thing we can do is disconnect. 47 00:03:05,710 --> 00:03:12,000 And reconnect that network adaptor that will jog things just like unplugging and putting them back in, 48 00:03:12,010 --> 00:03:13,680 you can see where disconnected. 49 00:03:13,780 --> 00:03:15,530 And then we'll be reconnected again. 50 00:03:16,990 --> 00:03:22,360 And then we can say IP A to get IP address tonight at three to four. 51 00:03:22,360 --> 00:03:23,050 Looks correct. 52 00:03:23,080 --> 00:03:24,550 So we are in really good shape. 53 00:03:24,970 --> 00:03:29,650 But let's do one other thing and I'll do a control l to clear my screen. 54 00:03:30,850 --> 00:03:34,390 Let's see how to restart the networking just in case those three steps don't work. 55 00:03:34,450 --> 00:03:38,770 You can say Sudoku or pseudo service. 56 00:03:40,040 --> 00:03:47,450 Networking or network manager, manager restart on some versions of Linux. 57 00:03:47,810 --> 00:03:49,430 And then your Pat Kelly password. 58 00:03:49,450 --> 00:03:49,820 K. 59 00:03:50,150 --> 00:03:50,510 I. 60 00:03:52,370 --> 00:03:57,680 There we go, and some versions of Linux, you'll say, see a pseudo service networking, restart the 61 00:03:57,680 --> 00:04:02,010 network manager on Kalli DPN, a new boon to Linux's. 62 00:04:02,360 --> 00:04:06,680 We'll give you a full restart of all of your network settings. 63 00:04:07,040 --> 00:04:14,990 So now if we do an IPA, we will see we do have 10 dot dot three, dot four as our Internet address. 64 00:04:15,590 --> 00:04:20,810 And notice that we have a loop back or our local host address to 127 dot audette odah one. 65 00:04:20,810 --> 00:04:23,630 That's always your home address on any computer. 66 00:04:24,320 --> 00:04:32,030 But then we have a network address on our home network on Ethernet zero Ethernet ethe zero is just the 67 00:04:32,030 --> 00:04:33,080 interface or the. 68 00:04:33,230 --> 00:04:39,320 It's just like plugging in a physical ethernet cable like you might have had on a desktop, at school 69 00:04:39,320 --> 00:04:39,830 or at work. 70 00:04:40,400 --> 00:04:43,710 So send out Odah three, not four is our Caleigh IP address. 71 00:04:43,850 --> 00:04:48,080 So we've got the ability to see other machines inside the network. 72 00:04:48,350 --> 00:04:54,140 So let's go over to our Windows machine and go ahead and make sure that its IP address came through. 73 00:04:54,140 --> 00:04:54,380 Okay. 74 00:04:54,440 --> 00:04:58,120 And then we'll check Medda spoil it can be the trickiest to setup. 75 00:04:58,520 --> 00:05:02,630 So I'll start my Windows 10 box and I'll go ahead and start the Mideast political box at the same time. 76 00:05:04,400 --> 00:05:08,780 When my windows virtual machine boots up, I'll be able to log in with the password. 77 00:05:09,080 --> 00:05:09,950 Capital P. 78 00:05:10,340 --> 00:05:14,150 Little a ss w zero r d exclamation. 79 00:05:14,700 --> 00:05:16,130 And I'll show that one more time. 80 00:05:16,220 --> 00:05:17,570 Just so that it's visible for you. 81 00:05:17,990 --> 00:05:21,470 Password with a zero in place of the O. 82 00:05:21,700 --> 00:05:22,670 A capital P. 83 00:05:22,790 --> 00:05:23,900 And an exclamation. 84 00:05:24,680 --> 00:05:26,360 That's Microsoft's password, remember. 85 00:05:26,360 --> 00:05:27,020 Not ours. 86 00:05:27,090 --> 00:05:28,970 But that's all right for this one, Veum. 87 00:05:30,490 --> 00:05:36,490 When we get inside our Windows 10 desktop, we can click in the START menu or search bar and say see 88 00:05:36,940 --> 00:05:38,680 these to run the command prompt. 89 00:05:40,330 --> 00:05:48,610 And we're going to say IP config instead of IP space A on a Windows box, and you notice we didn't get 90 00:05:48,610 --> 00:05:50,530 a 10 that ODAH three address. 91 00:05:50,560 --> 00:05:53,230 This computer is 10, DataDot three to five. 92 00:05:53,680 --> 00:05:59,110 And now actually we can check to see if we really can see other computers on this network by pinging 93 00:05:59,110 --> 00:06:01,060 P.I. in G space. 94 00:06:01,360 --> 00:06:04,390 And my Kelly Linux machine is still running in the background here. 95 00:06:04,780 --> 00:06:09,630 So I can say Tim Dotto, dot three, dot four. 96 00:06:10,120 --> 00:06:13,120 That was the IP address of my Caleigh Linux computer. 97 00:06:13,750 --> 00:06:18,310 And so if Windows is on the same network and everything's working correctly, we should be able to ping 98 00:06:18,850 --> 00:06:21,010 10 that audette three to four. 99 00:06:21,880 --> 00:06:22,660 And look at that. 100 00:06:22,690 --> 00:06:23,650 We get a reply. 101 00:06:25,350 --> 00:06:32,280 So we do have our Kelly and Linda Windows Live boxes connected to the same private hosts only network. 102 00:06:32,690 --> 00:06:37,560 I'd just one little troubleshooting tip if you ever get in here and you can't get your Windows computer 103 00:06:37,560 --> 00:06:40,950 to change addresses to the Tendo Doda, three to four network. 104 00:06:41,340 --> 00:06:43,170 We can do the same thing we did before. 105 00:06:43,170 --> 00:06:46,440 We can check our network settings down here under network settings. 106 00:06:46,950 --> 00:06:49,950 I can see that it is on the hosted only adapter, so that's OK. 107 00:06:50,640 --> 00:06:55,210 And then I can disconnect and reconnect that network adapter. 108 00:06:55,290 --> 00:06:56,190 Good troubleshooting. 109 00:06:56,700 --> 00:07:00,460 But there's one other step just in case your IP address doesn't come up right. 110 00:07:01,050 --> 00:07:04,890 This time I'm going to open an administrator command, prompt CMB. 111 00:07:05,700 --> 00:07:09,680 But instead of pressing enter, I'm going to say run as administrator. 112 00:07:09,690 --> 00:07:13,860 This is sort of like the super user do the pseudo command in Caleigh Linux. 113 00:07:14,130 --> 00:07:18,870 We're going to run as administrator and then we'll have to give it permission, just like entering the 114 00:07:18,870 --> 00:07:19,380 password. 115 00:07:19,380 --> 00:07:24,360 And Kelly and the command that we want to run is Net S.H. and E.T.. 116 00:07:24,450 --> 00:07:28,530 S.H., the network shell lets us run some network administration commands right here. 117 00:07:29,160 --> 00:07:31,380 Net S.H. Windsock. 118 00:07:33,690 --> 00:07:38,360 That's the window socket or Windows network manager, Windsock Recept. 119 00:07:38,860 --> 00:07:42,280 It's not restart like it is over on Kalli, but reset. 120 00:07:42,610 --> 00:07:46,000 So we successfully reset the wind set cattle at Windsock catalog. 121 00:07:46,360 --> 00:07:47,500 Now IP config. 122 00:07:48,070 --> 00:07:52,780 And we should have a good 10 tattoed three address on the same network. 123 00:07:53,530 --> 00:07:54,310 So finally. 124 00:07:55,060 --> 00:07:58,120 And we can save the settings there if we want to and close this down. 125 00:07:58,450 --> 00:07:59,560 Let's see how we can change. 126 00:07:59,560 --> 00:08:01,060 Made a split Tibbles IP address. 127 00:08:01,090 --> 00:08:02,140 It's a little bit different. 128 00:08:02,710 --> 00:08:08,140 The good thing is rebooting most of these machines does usually work to give us a fresh IP address. 129 00:08:08,440 --> 00:08:09,640 But we'll check that with M. 130 00:08:09,690 --> 00:08:14,440 S F 80s EMI N and MSF a.T.M I. 131 00:08:14,440 --> 00:08:15,940 N as our password. 132 00:08:16,480 --> 00:08:23,320 And we're on old Linux box so we can do I-F config, the interface config. 133 00:08:23,380 --> 00:08:26,110 I have config just like IP config over on windows. 134 00:08:26,590 --> 00:08:32,680 And notice because we had rebooted this machine, we do have a 10 Dotto dot three dot six address for 135 00:08:32,700 --> 00:08:33,850 our met hospitable box. 136 00:08:34,150 --> 00:08:40,450 But if you run into any trouble here, an easy way to pu to fix that on an older Linux box like the 137 00:08:40,450 --> 00:08:43,030 one you have here is Sudoku pseudo. 138 00:08:44,310 --> 00:08:50,070 F down and you notice that our Ethernet interface is called eath zero. 139 00:08:50,200 --> 00:08:51,850 E t h zero. 140 00:08:53,020 --> 00:08:59,800 And then we can use the double ampersand to then if the pseudo if down works correctly, we want to 141 00:08:59,800 --> 00:09:04,900 do a pseudo and bring the interface the IMF back up. 142 00:09:04,960 --> 00:09:07,240 So I f up ethe zero. 143 00:09:09,210 --> 00:09:12,870 And it lasts for the password for my Metis floatable. 144 00:09:13,470 --> 00:09:16,980 So we're going to say MSF a b m i n. 145 00:09:21,570 --> 00:09:29,220 There we go, and we now have a 10 DRDO three, that's six IP address for Metis Floatable. 146 00:09:29,220 --> 00:09:33,530 So all of three of these computers are set up with a good IP address. 147 00:09:33,540 --> 00:09:36,540 And we went ahead and changed the one for the Android device as well. 148 00:09:36,960 --> 00:09:40,800 So you can save these machine states if you want to as you power them off. 149 00:09:41,610 --> 00:09:48,840 And we'll come back in the next lesson and see how to connect to a new public network that will be able 150 00:09:48,840 --> 00:09:51,810 to do some hacking and connect out to the Internet with.
