1 00:00:00,280 --> 00:00:05,650 And Lou everybody when it comes to my advanced ethical hacking networking penetration testing goes 2 00:00:15,740 --> 00:00:19,870 this lab will cover the settlement of firewall any any network. 3 00:00:19,870 --> 00:00:26,350 Well you have many computers or many devices which are connected to a specific servers and then you 4 00:00:26,440 --> 00:00:35,920 and your firewall so that the connection from point A to Point B can be interconnected it can go through 5 00:00:36,070 --> 00:00:37,380 the firewall. 6 00:00:37,390 --> 00:00:38,100 All right. 7 00:00:38,140 --> 00:00:41,280 So we use this software Cisco package for Assad. 8 00:00:41,380 --> 00:00:43,370 You can find it on Google tried to go with it. 9 00:00:43,390 --> 00:00:53,510 And according to your version you can download it either if you are on Mark or on Windows or bomb went 10 00:00:53,520 --> 00:00:56,170 do stuff like that you can travel inside. 11 00:00:56,470 --> 00:01:04,780 So before going into the death let's have an overview of what is exactly the Cisco packets the Cisco 12 00:01:04,780 --> 00:01:12,610 packet transferred is a similar to software that is used for similar switches routers and order networking 13 00:01:12,610 --> 00:01:20,530 devices Cisco devices are genuinely expensive and can not invest in them to test and learn different 14 00:01:20,530 --> 00:01:22,400 topic of networking. 15 00:01:22,480 --> 00:01:29,860 And so you while you downloading it so it's better when you are going to learn sheet to turn off your 16 00:01:29,860 --> 00:01:38,310 Internet connection otherwise you have to look again to net Academy account so that you can proceed. 17 00:01:38,320 --> 00:01:44,810 So we would require to First thing first when you get out range your Cisco packet. 18 00:01:44,860 --> 00:01:52,440 So you have to disconnect from the Internet so that you can continue practicing offline. 19 00:01:52,450 --> 00:01:53,380 All right. 20 00:01:53,380 --> 00:02:00,220 First of all you need to in all in this Cisco certified network associate Academy program to download 21 00:02:00,220 --> 00:02:07,750 it for free of course but since August 2017 everyone can download Cisco packets and that is very very 22 00:02:07,750 --> 00:02:09,250 very nice. 23 00:02:09,250 --> 00:02:13,720 So it is a very powerful software from Cisco. 24 00:02:13,720 --> 00:02:20,350 It is a network simulation software helping student as I said earlier two choice packets and test the 25 00:02:20,350 --> 00:02:24,730 multiple test cases without using any external hardware. 26 00:02:24,820 --> 00:02:31,440 For example here we use different computers from a point B we to go. 27 00:02:31,480 --> 00:02:38,560 So a screech and then we connect and wrote a piece in this piece is this specific P.C. which used for 28 00:02:38,560 --> 00:02:45,730 this settlement for a base of the firewall which has all the properties of the firewall. 29 00:02:45,730 --> 00:02:51,410 So that's why we connect it with the firewall with a new keyboard that cable can find it. 30 00:02:51,850 --> 00:02:54,970 And then it's called consort keyboard. 31 00:02:54,970 --> 00:02:55,360 All right. 32 00:02:55,360 --> 00:03:03,880 So when all B.S. here they are going to this switch they have to go form the switch one and then connected 33 00:03:03,880 --> 00:03:07,200 to the server and then go here I. 34 00:03:07,330 --> 00:03:11,530 If we delay or if we used this connection they will go to the firewall. 35 00:03:11,560 --> 00:03:14,140 So here we have two words. 36 00:03:14,200 --> 00:03:21,010 I mean two ways so that they can go either they go straight forward coming here to you and to the window 37 00:03:21,100 --> 00:03:21,820 is you will. 38 00:03:21,980 --> 00:03:23,560 All they can cohere. 39 00:03:23,980 --> 00:03:31,060 But what we can do we can try to erase distilling and put it away. 40 00:03:31,060 --> 00:03:37,270 So now our computer we will have only one way to go to this whether it is from the firewall. 41 00:03:37,270 --> 00:03:37,770 All right. 42 00:03:37,930 --> 00:03:39,310 So let's go. 43 00:03:39,610 --> 00:03:42,700 It is also helpful for network administrator. 44 00:03:43,080 --> 00:03:43,750 All right. 45 00:03:43,750 --> 00:03:51,190 You need to continue as a guest if you want to download it or if you don't want if you have a net kind 46 00:03:51,190 --> 00:03:58,270 of cut any account you can arrange it while you are online while your internet is who is tweeting is 47 00:03:58,360 --> 00:03:59,350 switching on. 48 00:03:59,860 --> 00:04:00,390 OK. 49 00:04:00,610 --> 00:04:08,330 So some features of it the features of Cisco Packet Tracer letters vision you have precision time protocol 50 00:04:08,350 --> 00:04:16,370 P2P and ADP airspeed a and always in an Internet protocol and Internet of Things. 51 00:04:16,780 --> 00:04:17,800 Internet of Things. 52 00:04:17,830 --> 00:04:21,520 I already put Of course I did need I did. 53 00:04:21,520 --> 00:04:31,540 Improved support for the programming tab added in I O E configuration box javascript and CSA as support 54 00:04:31,810 --> 00:04:33,610 added for Cisco TTP server. 55 00:04:33,610 --> 00:04:34,670 That's very cool. 56 00:04:35,770 --> 00:04:40,430 That's very cool poverty and Cisco packets transfers the following application. 57 00:04:40,420 --> 00:04:44,430 That's what a core manager the HCV. 58 00:04:44,500 --> 00:04:46,100 We will show you DNS. 59 00:04:46,100 --> 00:04:58,600 We will show you an issue TB and or a P O P T N T P S M P S S H telnet or loose guy supported by the 60 00:04:58,600 --> 00:05:00,190 Cisco packet choice. 61 00:05:00,370 --> 00:05:07,180 So you will have Y and downloading that you will have a very good tool for networking penetration in 62 00:05:07,630 --> 00:05:14,950 networking testing or simulation to try to configure your firewall configure your server your computer 63 00:05:14,980 --> 00:05:18,400 without needed any kind of external devices. 64 00:05:18,970 --> 00:05:30,160 Okay so now let's let's just let's go to the practical part just we will not start with with D with 65 00:05:30,160 --> 00:05:31,000 you of course not. 66 00:05:31,000 --> 00:05:36,020 We will go step by step it's this step by step process how how you can do it. 67 00:05:36,700 --> 00:05:38,120 Oh right here. 68 00:05:38,170 --> 00:05:46,510 Just for a quick overview we are on we are timed so as usual when you launch your Cisco packet tracer 69 00:05:47,470 --> 00:05:55,690 you have you would have these things here you have to click on the Smart will like that so that you 70 00:05:55,690 --> 00:05:58,040 have a discrete upgrade to abuse you. 71 00:05:58,060 --> 00:06:02,220 So now here we are going to check all on network. 72 00:06:02,560 --> 00:06:05,130 So we have to network. 73 00:06:05,140 --> 00:06:15,250 This is one network and this this this is one network one network and the waters ease and order network 74 00:06:16,000 --> 00:06:20,660 and d point B is the third network. 75 00:06:20,660 --> 00:06:21,440 All right. 76 00:06:21,490 --> 00:06:30,100 So we click here on this icon message as simple PD you click on it we click on any computer from the 77 00:06:30,250 --> 00:06:37,920 eight planed and then we click on any computer from the B point to see if it will be successful. 78 00:06:38,200 --> 00:06:48,640 Here we are successful sometimes after trying you might see that it is failed at the first time. 79 00:06:48,940 --> 00:06:54,360 Don't be so unaware or don't be so my vote would be so sad. 80 00:06:54,370 --> 00:07:01,720 Just try it again go again cricket and click on any click on any so that it would all. 81 00:07:01,780 --> 00:07:04,740 Sometimes it doesn't work according to the network. 82 00:07:05,150 --> 00:07:15,750 OK so it is simulation how the message get transferred from the a point to the B point is here as simulation. 83 00:07:15,940 --> 00:07:18,430 We are going to try it out and we click here. 84 00:07:19,120 --> 00:07:21,330 So let's see. 85 00:07:22,060 --> 00:07:38,460 So it's not working kids that are working it doesn't block doesn't book by 80 by any by a anything all 86 00:07:38,640 --> 00:07:39,630 right. 87 00:07:39,690 --> 00:07:41,250 So this is how it works. 88 00:07:41,670 --> 00:07:47,840 OK now let's switch over and let's let's start a new project. 89 00:07:47,970 --> 00:07:53,330 You have to click new anyone save okay. 90 00:07:53,350 --> 00:07:53,750 Are you sure. 91 00:07:53,760 --> 00:07:55,490 No I don't want. 92 00:07:55,550 --> 00:07:59,270 All right okay. 93 00:07:59,330 --> 00:08:03,600 Now you have a blank page in front of you. 94 00:08:03,620 --> 00:08:12,850 What you have to do down the page you will see some icons and click on the desktop computer in devices. 95 00:08:12,920 --> 00:08:16,780 Here are those icon and then you will click. 96 00:08:16,990 --> 00:08:20,240 So a disease network devices. 97 00:08:20,240 --> 00:08:21,320 What we don't need this. 98 00:08:21,400 --> 00:08:23,980 We need this one in devices. 99 00:08:24,110 --> 00:08:25,920 So we click on it like that. 100 00:08:26,330 --> 00:08:28,560 And then here you can choose. 101 00:08:28,700 --> 00:08:30,500 We can try to win this thing out. 102 00:08:30,540 --> 00:08:30,970 OK. 103 00:08:31,160 --> 00:08:37,880 So you are going to choose the piece in this top if you want or if you want laptop servers the thing 104 00:08:37,880 --> 00:08:38,530 that you want. 105 00:08:38,540 --> 00:08:40,350 You just choose it. 106 00:08:41,050 --> 00:08:41,620 Okay. 107 00:08:41,690 --> 00:08:43,700 And click on the blank page. 108 00:08:43,910 --> 00:08:51,500 We are to win you there do the same thing to win as many as this time you would want your network to 109 00:08:51,500 --> 00:08:52,040 have. 110 00:08:56,260 --> 00:08:56,780 OK. 111 00:08:56,900 --> 00:08:58,510 To do with the cue. 112 00:08:58,740 --> 00:09:05,150 We could kill again you can click. 113 00:09:05,150 --> 00:09:07,540 You can choose as many as you want. 114 00:09:07,560 --> 00:09:11,030 So let's choose this one. 115 00:09:11,030 --> 00:09:11,860 It should be enough. 116 00:09:11,900 --> 00:09:13,360 Okay. 117 00:09:13,520 --> 00:09:13,810 Yeah. 118 00:09:14,540 --> 00:09:15,700 Okay. 119 00:09:15,740 --> 00:09:22,060 So the next step now next to the end device is icon here. 120 00:09:22,060 --> 00:09:25,040 Here you will find an icon. 121 00:09:25,220 --> 00:09:27,260 Which name is it network devices. 122 00:09:27,260 --> 00:09:29,290 This one as I showed earlier. 123 00:09:29,390 --> 00:09:34,200 Choose it and choose switches on switches. 124 00:09:34,220 --> 00:09:35,310 Exactly. 125 00:09:35,450 --> 00:09:36,450 This one. 126 00:09:36,480 --> 00:09:40,630 So then we will pick up a switch. 127 00:09:40,640 --> 00:09:43,880 Twenty nine sixty. 128 00:09:44,100 --> 00:09:44,980 All right. 129 00:09:45,020 --> 00:09:47,610 So we put an a switch here. 130 00:09:47,740 --> 00:09:53,190 Now arguably you see from this starting point would have to connect the Internet. 131 00:09:53,190 --> 00:09:57,660 Campbell Cooper straight through would be found from the connection. 132 00:09:57,910 --> 00:10:02,520 Okay so let's go to the connection and let's try to Cooper Street. 133 00:10:02,540 --> 00:10:03,950 Look at this one. 134 00:10:04,160 --> 00:10:14,990 Now you're going to win or win all of your stuff here when you did women do. 135 00:10:16,720 --> 00:10:17,180 Ok. 136 00:10:19,530 --> 00:10:26,020 Fast internet which was fast internet and then we're winning it here which is any one of them. 137 00:10:26,030 --> 00:10:28,940 What if only we do it step by step. 138 00:10:29,010 --> 00:10:29,610 Again 139 00:10:32,230 --> 00:10:33,010 fast internet. 140 00:10:33,010 --> 00:10:36,010 They will win it here. 141 00:10:36,010 --> 00:10:39,030 The second one no step by step. 142 00:10:39,310 --> 00:10:46,950 We chose it first and then zero again going to switch move on which was this one. 143 00:10:46,960 --> 00:10:47,470 All right. 144 00:10:47,470 --> 00:10:48,310 So far so good. 145 00:10:48,940 --> 00:10:57,470 I think we do it is just click and drag and you can delete them delayed them. 146 00:10:57,470 --> 00:10:58,460 Yeah. 147 00:10:58,820 --> 00:10:59,430 All right. 148 00:10:59,470 --> 00:11:02,140 So you go now. 149 00:11:02,370 --> 00:11:09,390 The third option is you would have the clinic each switch to a particular router. 150 00:11:09,610 --> 00:11:13,210 Let's say that you have one starting point and one destination. 151 00:11:13,600 --> 00:11:17,110 So you have to have then two switches and two orders. 152 00:11:17,170 --> 00:11:21,270 If every you would want wanted to have its happen. 153 00:11:21,890 --> 00:11:32,560 Okay this busy again swishes here switches it here again. 154 00:11:32,600 --> 00:11:35,430 Same is true the same switch. 155 00:11:35,490 --> 00:11:39,130 Here again we connect them as we did earlier. 156 00:11:39,130 --> 00:11:56,770 Forty point a plus in Tunisia will you will one gain let's return it to the will graphic. 157 00:11:56,840 --> 00:11:58,860 All right so here we go. 158 00:11:59,000 --> 00:12:09,040 Now we have to do switches and we're going to choose also to routers where we can find the waters again 159 00:12:09,050 --> 00:12:10,050 we go to here. 160 00:12:10,530 --> 00:12:14,640 Let's see if we own routers so we can choose this one. 161 00:12:15,080 --> 00:12:21,290 And they could do it or you can eat it but again and again. 162 00:12:21,610 --> 00:12:26,590 And only water will be altered to put it here. 163 00:12:26,600 --> 00:12:27,370 All right. 164 00:12:27,410 --> 00:12:29,060 So far so good. 165 00:12:29,490 --> 00:12:37,030 Then click on your order one to change its property slide with two fingers to right side of the salad 166 00:12:37,370 --> 00:12:44,000 page in the physical tab you will see yellow the green light in a mixer click on it to turn it off. 167 00:12:44,000 --> 00:12:49,280 Then choose from the left side which say W I see. 168 00:12:49,460 --> 00:12:53,220 Let's let's just showing you click on here. 169 00:12:53,480 --> 00:12:55,900 We still later say that this is green. 170 00:12:55,970 --> 00:12:58,340 We have to turn it off turn it off. 171 00:12:58,880 --> 00:13:00,680 Now let's go here. 172 00:13:00,850 --> 00:13:02,020 Oh I. 173 00:13:02,120 --> 00:13:06,520 This one one deed that I see one. 174 00:13:06,590 --> 00:13:07,250 Click here. 175 00:13:08,120 --> 00:13:16,170 And we we need he therefore we can again put it on. 176 00:13:16,170 --> 00:13:16,740 All right. 177 00:13:16,950 --> 00:13:20,510 So do the same thing for the second quarter. 178 00:13:20,660 --> 00:13:27,660 We click and we say to Dwight we turn it off. 179 00:13:27,660 --> 00:13:28,070 Go. 180 00:13:28,080 --> 00:13:32,870 Here we choose this one. 181 00:13:33,470 --> 00:13:34,910 So we need air. 182 00:13:35,320 --> 00:13:39,780 And the black page and black oh yea. 183 00:13:39,970 --> 00:13:41,370 And we need it. 184 00:13:41,400 --> 00:13:41,870 Turn it off. 185 00:13:41,870 --> 00:13:42,730 So we turn it on. 186 00:13:43,280 --> 00:13:43,630 OK. 187 00:13:43,650 --> 00:13:44,930 Now it's a green preference. 188 00:13:45,530 --> 00:13:45,950 All right. 189 00:13:47,270 --> 00:13:54,740 So click the mixer icon again to turn the light on as we have just the wow. 190 00:13:54,940 --> 00:13:55,770 OK. 191 00:13:56,180 --> 00:14:05,150 So now you can connect you to what rose by choosing the CEO DC a cable and single 0 0 when clicking 192 00:14:05,150 --> 00:14:07,670 on your computer to put that cable. 193 00:14:07,670 --> 00:14:08,490 All right. 194 00:14:08,570 --> 00:14:16,150 Since we need a quote We have to go into quotation because it Campbell is a connection that joined to 195 00:14:16,160 --> 00:14:18,890 point a and b. 196 00:14:19,160 --> 00:14:24,420 Which one we have to choose the one that said singular DC is this one. 197 00:14:24,410 --> 00:14:24,880 No. 198 00:14:24,920 --> 00:14:25,540 Is this one. 199 00:14:25,540 --> 00:14:25,840 No. 200 00:14:25,850 --> 00:14:26,590 This one no. 201 00:14:26,600 --> 00:14:27,490 Is this one. 202 00:14:27,500 --> 00:14:28,610 No. 203 00:14:28,610 --> 00:14:29,120 Is this one. 204 00:14:29,130 --> 00:14:29,360 No. 205 00:14:29,390 --> 00:14:30,410 This one no. 206 00:14:30,470 --> 00:14:32,070 You know every thing. 207 00:14:32,100 --> 00:14:32,490 Oh. 208 00:14:32,730 --> 00:14:36,530 Oh then they have do names like Eagle beetle. 209 00:14:36,560 --> 00:14:38,210 So this is a good step. 210 00:14:38,780 --> 00:14:43,070 So we'll tweak it and then we click you. 211 00:14:43,610 --> 00:14:48,730 What we have to choose now not fast internet zero because it's a order. 212 00:14:48,800 --> 00:14:55,040 We need to just choose sealed order and then click and wait here. 213 00:14:55,220 --> 00:14:56,800 Oh I see your. 214 00:14:56,970 --> 00:14:58,770 All right. 215 00:14:58,830 --> 00:15:09,750 Okay so Craig now on a P.C. choose the desktop tab and a B continuation let's step by step desktop IP 216 00:15:09,960 --> 00:15:19,800 configuration so that makes them few changes and what we have to do we have to make our IP address. 217 00:15:19,800 --> 00:15:27,210 We have to take any IP not any IP address but it might be good to put it in a specific range. 218 00:15:27,630 --> 00:15:28,000 All right. 219 00:15:28,000 --> 00:15:34,860 Put something like 1 9 2 1 6 8 and so on and so so that you keep it as static. 220 00:15:35,310 --> 00:15:35,750 All right. 221 00:15:35,750 --> 00:15:36,660 So let's go. 222 00:15:36,780 --> 00:15:49,150 We put 1 1 6 8 1 9 2 1 6 8 and then we can take and then say oh we start from 4 4. 223 00:15:49,510 --> 00:15:50,230 All. 224 00:15:50,750 --> 00:15:53,260 So where do we put. 225 00:15:53,310 --> 00:15:56,170 We don't put one because we just leave it. 226 00:15:56,250 --> 00:16:01,550 We just leave it for a default gateway for what did we. 227 00:16:01,890 --> 00:16:03,690 I mean for the seed. 228 00:16:03,690 --> 00:16:11,160 So as you might see so we can just copy in control C or come and see anybody that be okay. 229 00:16:11,190 --> 00:16:14,200 This is an invalid IP whites that invalid. 230 00:16:14,240 --> 00:16:15,120 Okay. 231 00:16:15,240 --> 00:16:20,230 We we know I should be dead from then. 232 00:16:20,610 --> 00:16:21,070 All right. 233 00:16:21,070 --> 00:16:21,420 It's good. 234 00:16:21,420 --> 00:16:32,510 No one told me this is the scene one one's copy that we make those changes. 235 00:16:32,550 --> 00:16:33,060 Is great. 236 00:16:33,200 --> 00:16:36,960 Now if we have a server we can put the server name here. 237 00:16:37,030 --> 00:16:40,840 But as we are not going into the server for now. 238 00:16:40,840 --> 00:16:42,020 So we lead it. 239 00:16:42,100 --> 00:16:43,560 We let it as a default. 240 00:16:43,740 --> 00:16:44,240 Okay. 241 00:16:44,250 --> 00:16:52,170 So click here and close to do the same thing for all of your pieces. 242 00:16:52,450 --> 00:16:59,210 Again they stop IP configuration and type copying bass. 243 00:16:59,490 --> 00:17:08,980 So we were at folks or would you automatically get it has this subclass and plus the default get right 244 00:17:08,990 --> 00:17:10,320 here. 245 00:17:10,410 --> 00:17:12,090 Great control. 246 00:17:12,390 --> 00:17:14,490 The same again and again. 247 00:17:20,150 --> 00:17:20,690 Six 248 00:17:25,570 --> 00:17:26,300 one. 249 00:17:26,320 --> 00:17:26,850 Okay. 250 00:17:26,920 --> 00:17:29,850 Close go here. 251 00:17:31,670 --> 00:17:31,960 So 252 00:17:40,570 --> 00:17:52,720 now as we we we are now at the B point try because scenes this part is a block of computers. 253 00:17:52,850 --> 00:17:54,890 And then this part is a go of computer. 254 00:17:54,890 --> 00:17:57,940 So let's say that they are not in the same range. 255 00:17:58,070 --> 00:18:04,790 So we can put it e now like instead of one. 256 00:18:04,820 --> 00:18:06,350 So we can board. 257 00:18:06,460 --> 00:18:15,680 That's a DCD then and we start again at full C form. 258 00:18:15,940 --> 00:18:16,430 Okay. 259 00:18:17,710 --> 00:18:20,980 So the scene now is the only one. 260 00:18:22,360 --> 00:18:25,740 So it would ten days is exactly how it would look. 261 00:18:25,740 --> 00:18:26,130 All right. 262 00:18:26,530 --> 00:18:33,260 So we copy the seed because we really need it for the contribution of the next device. 263 00:18:34,270 --> 00:18:35,250 So we go here. 264 00:18:36,620 --> 00:18:39,800 This thing direction. 265 00:18:40,750 --> 00:18:42,100 Yeah. 266 00:18:42,150 --> 00:18:45,490 And I use that as well. 267 00:18:46,140 --> 00:18:48,570 Okay. 268 00:18:48,660 --> 00:18:49,200 Copy. 269 00:18:49,860 --> 00:18:50,130 Yeah. 270 00:18:50,550 --> 00:18:55,220 So we cross it now very good 271 00:19:01,310 --> 00:19:08,270 when you are done with your P.C. with all of them click on a router then choose the commentary tab. 272 00:19:08,960 --> 00:19:11,260 So when I try to click here 273 00:19:13,960 --> 00:19:14,950 OK. 274 00:19:15,090 --> 00:19:16,750 Now we click on conflict tab. 275 00:19:17,580 --> 00:19:28,460 Then right after we have to go to the CBO numbers you see our number you see our number is is 1 0 2 276 00:19:28,460 --> 00:19:28,910 0. 277 00:19:29,120 --> 00:19:29,850 Okay. 278 00:19:29,990 --> 00:19:37,910 Now put the clock weight to something like let's say let's say that it is on 2 million. 279 00:19:38,120 --> 00:19:39,330 If I'm seeing it right. 280 00:19:39,360 --> 00:19:39,780 Okay. 281 00:19:39,780 --> 00:19:41,340 So we put it like 282 00:19:44,580 --> 00:19:48,620 one hundred twenty eight dollars. 283 00:19:48,810 --> 00:19:51,170 Anything like that. 284 00:19:52,150 --> 00:19:58,920 And so where and then is IP address mostly different as the computer's address. 285 00:19:58,920 --> 00:19:59,530 All right. 286 00:19:59,580 --> 00:20:01,890 So put it like something. 287 00:20:01,890 --> 00:20:10,770 1 1 9 2 let's say 1 9 2 1 9 2 1 6 8. 288 00:20:10,810 --> 00:20:21,170 And it's neat to see on which side we have this anybody that I know I could feel it yet. 289 00:20:22,090 --> 00:20:22,730 OK. 290 00:20:23,020 --> 00:20:26,330 Let's see 1 4. 291 00:20:26,420 --> 00:20:29,390 It was 1 OK. 292 00:20:29,860 --> 00:20:31,270 So we can put it like 293 00:20:35,990 --> 00:20:53,410 one 1 these days and then let's say it's see on to an unexpected three in here. 294 00:21:04,530 --> 00:21:09,430 Then one one day. 295 00:21:09,760 --> 00:21:14,830 And had to do this that was one that was on. 296 00:21:15,250 --> 00:21:20,440 Okay so and close it do the same thing for all of your photos. 297 00:21:20,450 --> 00:21:25,460 It depends on how many waters you you have put on your network. 298 00:21:25,460 --> 00:21:33,050 So we have only to do so we have to go and do something for you on it for the owner and for the only 299 00:21:33,050 --> 00:21:33,320 one. 300 00:21:33,920 --> 00:21:34,270 All right. 301 00:21:35,060 --> 00:21:37,650 So let's check again output OCD. 302 00:21:37,770 --> 00:21:47,410 OCD one do all of us Ed you used to be do. 303 00:21:47,960 --> 00:21:48,680 All right. 304 00:21:48,890 --> 00:21:53,720 You're gonna say take in a good moment. 305 00:21:54,180 --> 00:21:56,550 We have to check this one. 306 00:21:56,610 --> 00:21:59,970 I need you Stan. 307 00:22:00,000 --> 00:22:00,390 Okay. 308 00:22:02,280 --> 00:22:05,100 Then let's go back. 309 00:22:05,210 --> 00:22:15,170 You know or convened that go here do the same thing. 310 00:22:16,010 --> 00:22:18,980 So what kind of theme I put there. 311 00:22:19,520 --> 00:22:28,980 You would not try to put it on one me eight injuries one to one saves. 312 00:22:29,300 --> 00:22:32,620 It has been on three. 313 00:22:32,640 --> 00:22:34,420 Now let's put it this on the phone. 314 00:22:35,510 --> 00:22:38,840 Okay now let's go here. 315 00:22:40,420 --> 00:22:43,660 So IP address on the seed. 316 00:22:44,100 --> 00:22:45,300 This it was 317 00:22:48,010 --> 00:22:48,370 Seed 318 00:22:51,030 --> 00:22:58,580 1 1. 319 00:23:01,500 --> 00:23:02,110 Okay. 320 00:23:02,180 --> 00:23:10,620 So and what the was click on great Exelon and close it right. 321 00:23:11,080 --> 00:23:14,040 Okay next things you have to do. 322 00:23:14,170 --> 00:23:21,730 So you have to click on on your orders so a different order after clicking on it you're going to try 323 00:23:21,730 --> 00:23:29,500 to go to the common line interface and and type in it to leave the E config. 324 00:23:29,500 --> 00:23:38,220 So let's go right here we've got to go online indifference so here we are. 325 00:23:38,340 --> 00:23:44,980 We are in the global configuration mode since we have config. 326 00:23:45,050 --> 00:23:50,020 And if so we have to take it so that we will leave it. 327 00:23:50,040 --> 00:23:50,940 All right. 328 00:23:50,940 --> 00:24:04,290 So now we have to take IP would IP would be 0 0 0 0 0 0 0 0. 329 00:24:04,310 --> 00:24:06,330 Space we have to put space here. 330 00:24:06,380 --> 00:24:15,650 So we were put into it and then now 1 9 2 1 6 8. 331 00:24:16,400 --> 00:24:22,880 What kind of what kind of seed we had for this one. 332 00:24:23,000 --> 00:24:23,480 It's good. 333 00:24:23,480 --> 00:24:24,190 It is. 334 00:24:24,200 --> 00:24:26,060 Copy. 335 00:24:26,070 --> 00:24:30,320 Copy it is received. 336 00:24:30,360 --> 00:24:42,040 Will you visit yet check it see this see the windows too. 337 00:24:42,130 --> 00:24:42,820 All right. 338 00:24:43,260 --> 00:24:52,100 So let's pass it on so we get an 339 00:24:55,270 --> 00:24:55,950 was it one. 340 00:24:56,870 --> 00:25:00,280 Yep yep yep yep yep. 341 00:25:03,220 --> 00:25:09,920 Good us then me. 342 00:25:10,390 --> 00:25:17,130 And then when I put under invalid input detected in marker. 343 00:25:17,520 --> 00:25:18,580 All right. 344 00:25:18,590 --> 00:25:18,820 Yeah. 345 00:25:18,890 --> 00:25:26,580 So it's not one we have is we these wounds will. 346 00:25:26,630 --> 00:25:27,380 Exactly. 347 00:25:27,460 --> 00:25:28,660 So any any. 348 00:25:28,830 --> 00:25:31,460 And then the IP address. 349 00:25:31,500 --> 00:25:33,030 So this will do it 350 00:25:36,040 --> 00:25:36,720 invalid. 351 00:25:36,730 --> 00:25:37,840 Okay. 352 00:25:37,980 --> 00:25:41,890 Take this one because this is the world. 353 00:25:41,920 --> 00:25:45,580 So we cannot put the same IP wood for it. 354 00:25:45,580 --> 00:25:46,140 Exactly. 355 00:25:46,160 --> 00:25:49,120 So now it's okay. 356 00:25:49,270 --> 00:25:51,420 And then typing it too easy. 357 00:25:52,600 --> 00:25:58,270 So we went into console no default default for a. 358 00:25:58,330 --> 00:25:59,590 What they mean. 359 00:25:59,590 --> 00:26:09,360 They mean that any IP address from the a point from the a planed and then the first the first for the 360 00:26:09,370 --> 00:26:19,340 second for ze will means that any IP address addresses form the second plane in IP address from the 361 00:26:19,340 --> 00:26:24,170 second point being let's say this is B and this is a point all right. 362 00:26:24,440 --> 00:26:28,170 So that's how it is. 363 00:26:28,770 --> 00:26:37,380 Likewise we do the same thing for the single do with the IP would it present the days the seed on which 364 00:26:37,480 --> 00:26:40,070 they would do one or two would do. 365 00:26:40,470 --> 00:26:42,420 He was on. 366 00:26:42,470 --> 00:26:42,910 Okay. 367 00:26:45,680 --> 00:26:48,530 Now you have put it on 3 1. 368 00:26:48,530 --> 00:26:49,650 So this is the base. 369 00:26:49,670 --> 00:26:50,180 All right. 370 00:26:50,240 --> 00:26:57,280 So let's leave the shell now going to the same thing for the two. 371 00:26:57,300 --> 00:26:58,710 So when I go to here. 372 00:26:59,600 --> 00:27:05,420 So first thing first let's check on how it was for 10. 373 00:27:05,420 --> 00:27:08,510 So that means it would be for 1 0. 374 00:27:08,780 --> 00:27:18,930 So we type we to during the global contribution what is it now we can type IP would say it's just past 375 00:27:18,950 --> 00:27:26,890 the comment we have compiled before and here the book for one. 376 00:27:27,030 --> 00:27:28,890 Oh yes. 377 00:27:29,110 --> 00:27:33,970 Is this is this is is your knowledge of be it. 378 00:27:33,970 --> 00:27:35,410 One two three four. 379 00:27:36,440 --> 00:27:38,170 One two. 380 00:27:38,650 --> 00:27:38,970 Okay. 381 00:27:38,980 --> 00:27:39,330 What now. 382 00:27:39,350 --> 00:27:39,680 Each one. 383 00:27:39,710 --> 00:27:40,570 Okay. 384 00:27:40,620 --> 00:27:42,380 All right area. 385 00:27:42,400 --> 00:27:43,820 Here we go. 386 00:27:43,830 --> 00:27:44,460 Perfect. 387 00:27:45,340 --> 00:27:46,440 So we close it. 388 00:27:47,770 --> 00:27:57,280 Get very good now why do we need to do can we test it now. 389 00:27:57,440 --> 00:27:58,710 Absolutely not. 390 00:27:58,760 --> 00:28:05,310 Because the water should have to communicate wheat or sweet cheese. 391 00:28:05,360 --> 00:28:06,990 And this one and this one. 392 00:28:07,070 --> 00:28:14,690 If you had only one would do so and we did so you wouldn't have to connect the switch with the water 393 00:28:14,990 --> 00:28:24,260 and say if I want this switch to communicate with this dress or a click here icon and corporate steward 394 00:28:24,280 --> 00:28:28,140 too and I click on it and I do do I need to hear. 395 00:28:28,400 --> 00:28:32,630 But if I want this switch to belong to this water and this to this water. 396 00:28:32,720 --> 00:28:41,980 So when I have to do is the same is clicking and I create a safety net and don't get here. 397 00:28:42,750 --> 00:28:43,880 Right. 398 00:28:44,420 --> 00:28:54,700 Now when we are at this point what we have to do is Tuesdays came with the same thing 399 00:29:02,150 --> 00:29:02,540 or 400 00:29:06,690 --> 00:29:09,970 when I called well. 401 00:29:10,460 --> 00:29:19,910 So don't forget the gate we here should be the IP the first Internet IP of that order and then the first 402 00:29:19,930 --> 00:29:23,380 etude IP of that would it should be the gateway of these two. 403 00:29:24,140 --> 00:29:24,630 Let's. 404 00:29:24,650 --> 00:29:25,100 Over. 405 00:29:25,090 --> 00:29:25,800 Over. 406 00:29:25,890 --> 00:29:29,440 Amount was a hail. 407 00:29:29,700 --> 00:29:30,960 Let's try it. 408 00:29:31,060 --> 00:29:31,980 Okay. 409 00:29:32,100 --> 00:29:34,790 We see the gateway is. 410 00:29:35,090 --> 00:29:37,430 One is then one. 411 00:29:37,440 --> 00:29:38,300 Okay. 412 00:29:38,550 --> 00:29:41,820 We're going to check it out Internet. 413 00:29:41,910 --> 00:29:43,220 It's 10 1. 414 00:29:43,230 --> 00:29:44,030 Exactly. 415 00:29:44,420 --> 00:29:46,910 Oh if you want you can just over a mouse. 416 00:29:47,390 --> 00:29:54,880 And then you would see it then one IP address 1 9 2 1 6 8 10 1 slash 24. 417 00:29:54,900 --> 00:29:57,150 So let's take this one. 418 00:29:57,390 --> 00:30:03,570 The gateway is 1 1 1 1 1 1 should be the same. 419 00:30:03,610 --> 00:30:04,780 1 1. 420 00:30:04,910 --> 00:30:06,690 This should be the same of course. 421 00:30:07,620 --> 00:30:10,230 The Gateway in one way. 422 00:30:10,490 --> 00:30:11,240 Then one. 423 00:30:11,290 --> 00:30:11,890 Perfect. 424 00:30:11,900 --> 00:30:14,990 So 1 1 2 will behave as 1 1. 425 00:30:14,990 --> 00:30:15,530 Exactly. 426 00:30:15,560 --> 00:30:22,360 So let's click on it to make sure it's wide. 427 00:30:22,420 --> 00:30:22,840 All right. 428 00:30:22,840 --> 00:30:24,290 1 1 1. 429 00:30:24,560 --> 00:30:31,390 Now you can try to test your network to see if the connection will match. 430 00:30:31,530 --> 00:30:40,710 So OK let's try to do the connection click here to send messages. 431 00:30:41,650 --> 00:30:53,170 I mean you go to this computer this computer to see we have to check this first successful. 432 00:30:53,350 --> 00:31:04,000 It's chicken only one this one is one success one you do the last one because we don't have many. 433 00:31:04,050 --> 00:31:14,560 So it's a complex view we should all again successful. 434 00:31:14,830 --> 00:31:18,720 So what about to make the connection to the order. 435 00:31:18,790 --> 00:31:20,390 So let's try it out again. 436 00:31:20,470 --> 00:31:21,220 So let's first 437 00:31:26,280 --> 00:31:30,540 this computer do it successful. 438 00:31:31,040 --> 00:31:33,370 So now we might ask. 439 00:31:33,620 --> 00:31:40,390 I want this network to connect these from the a point to connect to the big point to point B. 440 00:31:40,390 --> 00:31:45,310 So okay so it trade but. 441 00:31:45,520 --> 00:31:46,190 What. 442 00:31:46,340 --> 00:31:55,000 OK let's do it for the purpose of this video and then we click on its core here you see. 443 00:31:55,650 --> 00:31:59,610 It's terrific in here. 444 00:31:59,630 --> 00:32:12,290 Put it in think the reason behind this is that these computer cannot which due to this part of the network 445 00:32:12,770 --> 00:32:19,880 because these orders they don't know how to get how to switch to each other you know. 446 00:32:20,510 --> 00:32:30,020 So when the connection start from here and fluently softly it goes to two or switch to here easily. 447 00:32:30,170 --> 00:32:31,640 What we need is here. 448 00:32:31,760 --> 00:32:36,780 This water doesn't know how to call heat because they are not on the same network. 449 00:32:36,780 --> 00:32:41,130 You see they don't know how to get to each other. 450 00:32:41,180 --> 00:32:47,440 What we need to do we have to configure the IP world so that the IP world. 451 00:32:47,510 --> 00:32:50,270 When we say dogs now do we know. 452 00:32:50,270 --> 00:32:51,200 Aha. 453 00:32:51,230 --> 00:32:52,880 I have to go to this world. 454 00:32:52,940 --> 00:32:54,470 I have to go this way. 455 00:32:54,470 --> 00:32:55,190 All right. 456 00:32:55,190 --> 00:32:58,580 So now let's let's start and make it. 457 00:32:58,910 --> 00:33:02,500 We have to click now on the order one. 458 00:33:02,510 --> 00:33:03,680 This is all. 459 00:33:04,130 --> 00:33:12,030 This is always and we have to go to the common light interface see it I away. 460 00:33:12,090 --> 00:33:15,970 So now automatically we are in the global configuration. 461 00:33:16,020 --> 00:33:19,280 This is the global configuration modem. 462 00:33:19,620 --> 00:33:26,790 So we have to exhibit that we can exist existing prisoner preferred. 463 00:33:27,000 --> 00:33:35,430 So now we can type what we want to type in the IP world IP wallet and 0 0 0 0. 464 00:33:35,460 --> 00:33:42,340 As we have said earlier the zoo is a computer it is any computer. 465 00:33:42,550 --> 00:33:53,920 The starting point between space 0 0 0 0 that means a computer from the destination point. 466 00:33:53,950 --> 00:33:56,370 Now we're going to set. 467 00:33:56,440 --> 00:34:00,350 So now we can set the IP of the wonder. 468 00:34:00,570 --> 00:34:08,230 So the IP of the 12 is 1 9 2 0 1 6 8. 469 00:34:09,660 --> 00:34:12,240 And then what next. 470 00:34:12,240 --> 00:34:18,160 The IP of the audit is 1 9 2 1 3 1. 471 00:34:18,190 --> 00:34:23,820 So deceived by the new presenter O K incident 472 00:34:27,270 --> 00:34:28,660 a mistake. 473 00:34:28,810 --> 00:34:37,090 Some students always do or even some potential is by forgetting to put teams in order. 474 00:34:37,180 --> 00:34:41,980 For example they can forget the seed of D and how things are working. 475 00:34:42,200 --> 00:34:42,670 OK. 476 00:34:43,690 --> 00:34:49,110 Let's put things in order for you here. 477 00:34:49,330 --> 00:34:50,560 We have order. 478 00:34:50,560 --> 00:34:53,680 So let's consider it as the first order. 479 00:34:53,680 --> 00:34:54,010 All right. 480 00:34:54,940 --> 00:34:56,830 So what do you do here. 481 00:34:57,220 --> 00:35:00,270 This is represented for us as the first order. 482 00:35:00,280 --> 00:35:00,760 All right. 483 00:35:00,760 --> 00:35:12,560 And then Campbell he might contain in a b d D1 to the order it contains a b b c your IP okay. 484 00:35:13,230 --> 00:35:16,210 So you see your IP 485 00:35:18,960 --> 00:35:20,790 Yeah this one. 486 00:35:21,250 --> 00:35:26,460 And he goes to the router D is an IP address. 487 00:35:26,470 --> 00:35:30,500 This is an IP address and he near who the switch as well. 488 00:35:30,820 --> 00:35:31,360 And here. 489 00:35:31,420 --> 00:35:31,890 OK. 490 00:35:32,240 --> 00:35:40,150 Now every thing that is connected easily keyed to an IP address. 491 00:35:40,170 --> 00:35:42,750 So let's let's type it. 492 00:35:42,960 --> 00:35:48,250 And so Joy we we expand how things is working. 493 00:35:48,560 --> 00:35:50,870 Please say not OK let's do it here. 494 00:35:52,510 --> 00:35:53,480 All right. 495 00:35:53,550 --> 00:35:57,550 So he is 0 to 1 1. 496 00:35:57,770 --> 00:35:59,130 It has an IP address. 497 00:36:00,120 --> 00:36:01,490 Okay. 498 00:36:01,800 --> 00:36:13,310 Now you we have is this silly are you single part of that who do one of your buddies that see young 499 00:36:14,510 --> 00:36:23,430 of the world to see 0 1 0 4 to 1. 500 00:36:27,040 --> 00:36:36,860 And the first internet connection fast internet connection is a wall or who do one food to one. 501 00:36:37,350 --> 00:36:39,790 It's a good one. 502 00:36:39,850 --> 00:36:46,080 One one do it again. 503 00:36:46,100 --> 00:36:55,540 So my future is now on the switch as an IP address. 504 00:36:55,540 --> 00:36:57,110 He right here. 505 00:36:57,600 --> 00:37:09,000 So it is to be switch IP address switch switch switch 506 00:37:12,450 --> 00:37:17,680 and heal from the switch to the P.C. zero. 507 00:37:17,750 --> 00:37:20,920 It has gone out to the edges of the switch. 508 00:37:21,430 --> 00:37:27,510 One is from the switch again and the P.C. to these. 509 00:37:27,800 --> 00:37:33,720 He has an IP address and the cable. 510 00:37:34,860 --> 00:37:41,520 Likewise the third one and the PCC will be seen zero has an IP address you see two 511 00:37:44,270 --> 00:37:55,980 pieces to this one that has an IP address on it put it under NBC do you see two that's an IP address. 512 00:37:55,980 --> 00:38:00,860 OK this is all that we have here. 513 00:38:01,920 --> 00:38:08,760 So far so good but if we want this serial number we can put it away. 514 00:38:08,850 --> 00:38:16,070 Let's control it so that we make this step by step process. 515 00:38:16,090 --> 00:38:16,480 All right. 516 00:38:16,650 --> 00:38:22,770 Now this is our first network now and this again network is to be here again. 517 00:38:22,850 --> 00:38:23,370 What is it. 518 00:38:24,180 --> 00:38:25,890 It is the water serial number now. 519 00:38:26,020 --> 00:38:28,710 Listen closely to it. 520 00:38:28,810 --> 00:38:31,310 You know right. 521 00:38:31,460 --> 00:38:32,520 So let's click here. 522 00:38:32,870 --> 00:38:42,040 So what can be for going into the dip in the water one we can call it the network one. 523 00:38:42,830 --> 00:38:51,000 Just like network one is in order to know it these days forward without this problem. 524 00:38:51,240 --> 00:38:51,710 All right. 525 00:38:52,340 --> 00:39:09,670 So now let's do the same thing for it to do so the CEO has an IP address. 526 00:39:09,810 --> 00:39:13,030 So this is silly on its the 527 00:39:16,580 --> 00:39:24,150 do you do go one on someone produce. 528 00:39:24,870 --> 00:39:29,250 Do you get an IP address. 529 00:39:29,350 --> 00:39:29,910 Wide 530 00:39:34,630 --> 00:39:36,260 look in here. 531 00:39:36,370 --> 00:39:40,600 Again it might have something like 532 00:39:43,840 --> 00:39:55,820 something like what the do you see or hear. 533 00:39:56,440 --> 00:40:02,030 You have something like to do. 534 00:40:04,100 --> 00:40:07,570 You can put it to 50 55. 535 00:40:07,890 --> 00:40:09,250 Oh OK. 536 00:40:09,290 --> 00:40:10,230 Now 55 537 00:40:14,740 --> 00:40:20,990 215 to be doo doo doo doo doo doo. 538 00:40:21,130 --> 00:40:21,700 OK. 539 00:40:22,100 --> 00:40:26,240 So now and this part is to be what you would like. 540 00:40:26,410 --> 00:40:27,280 Okay. 541 00:40:27,380 --> 00:40:31,470 Now what a network with network. 542 00:40:32,260 --> 00:40:36,820 We do the same thing for all network in 543 00:40:49,890 --> 00:40:50,260 right. 544 00:40:50,720 --> 00:41:02,830 So we have order let's say Luke and Nick order is would go to more. 545 00:41:02,910 --> 00:41:03,470 First. 546 00:41:03,560 --> 00:41:11,050 You can try to buy these people it's 547 00:41:14,930 --> 00:41:17,550 work well. 548 00:41:18,510 --> 00:41:26,070 So 0 2 2 what he does it has. 549 00:41:26,210 --> 00:41:37,890 First the first e the last but you good to do it. 550 00:41:37,920 --> 00:41:39,420 It has an IP address. 551 00:41:39,720 --> 00:41:52,050 This port is this port put a switch has an IP address to switch that's an IP address and you switch 552 00:41:52,140 --> 00:41:55,080 who you do this for you. 553 00:41:55,080 --> 00:42:04,340 It has an IP address days or so switch one an IP address and from here. 554 00:42:04,360 --> 00:42:17,330 Do you also switch to now AC to me maybe it's silly for an IP address. 555 00:42:17,330 --> 00:42:35,050 All right let's settle on at work you let's say we will put an IP it's the base 1 in 2 and 1 1 6 8 1 556 00:42:36,580 --> 00:42:37,050 0. 557 00:42:37,340 --> 00:42:39,810 Okay because it's to be the first. 558 00:42:39,940 --> 00:42:40,620 All right. 559 00:42:40,620 --> 00:42:41,530 And it's good on 560 00:42:46,070 --> 00:42:47,020 before. 561 00:42:47,280 --> 00:42:52,810 Each one on this which is all you do is also recorded. 562 00:42:52,840 --> 00:42:57,080 So each one because it is the first one but it's also never mind. 563 00:42:57,560 --> 00:42:57,910 Okay. 564 00:42:57,980 --> 00:43:05,500 So when you just copying past me and then you could tweak it's good I think that's the best thing you 565 00:43:05,710 --> 00:43:11,870 bought for we put. 566 00:43:11,920 --> 00:43:13,230 Here we are. 567 00:43:13,230 --> 00:43:21,730 So this is the 1 2 1 2 1 4 1 5. 568 00:43:21,750 --> 00:43:29,070 Now we are here therefore species 0 is 6 6. 569 00:43:29,080 --> 00:43:30,110 Let's go. 570 00:43:30,110 --> 00:43:32,350 You see two is 7. 571 00:43:32,360 --> 00:43:38,260 This one I mean you seem to use 8 Excellent. 572 00:43:38,890 --> 00:43:43,710 Now it is the same thing for wanted to on it with 2 of course. 573 00:43:44,010 --> 00:43:44,850 It has an IP. 574 00:43:44,880 --> 00:43:53,880 So the IP address can make can be 1 9 2 1 2 8 575 00:43:57,140 --> 00:43:57,970 2. 576 00:43:58,010 --> 00:44:01,240 Now in this law. 577 00:44:01,360 --> 00:44:08,990 All right because here we are on the second network so that's why we put two so that we put them in 578 00:44:09,110 --> 00:44:09,530 order. 579 00:44:09,560 --> 00:44:11,300 So this is exactly all good. 580 00:44:12,320 --> 00:44:13,300 Okay. 581 00:44:13,370 --> 00:44:16,820 So now we are going to copy again and pass it here. 582 00:44:17,180 --> 00:44:22,220 But instead of one we change all bases. 583 00:44:22,430 --> 00:44:26,610 I mean Oh see here we put it like two. 584 00:44:26,630 --> 00:44:33,790 So now we can put these one these these serial of what is this one. 585 00:44:33,950 --> 00:44:35,080 Exactly. 586 00:44:35,120 --> 00:44:40,760 This is 1 9 2 1 6 8 2 1. 587 00:44:40,800 --> 00:44:41,460 Okay. 588 00:44:41,520 --> 00:44:42,000 It would. 589 00:44:42,000 --> 00:44:43,830 It's base here. 590 00:44:44,230 --> 00:44:45,070 All right. 591 00:44:45,080 --> 00:44:47,090 So now we go here. 592 00:44:47,760 --> 00:45:00,080 But again we're going to change this scene from one to two and then now it it is to be to these one. 593 00:45:00,120 --> 00:45:03,190 Okay now let's go to our network here 594 00:45:07,400 --> 00:45:09,750 in on network. 595 00:45:10,040 --> 00:45:20,140 We might be quite the same again but instead of to see we would put a seed is 1 3 and 0. 596 00:45:20,740 --> 00:45:27,880 So we could eat copy so that we don't have to chain you yet again and again. 597 00:45:28,010 --> 00:45:34,280 Right know we're gonna have just copied and pasted it here and change it all when. 598 00:45:34,310 --> 00:45:42,800 But before that we forget to do the basic things we have to save it is if by accident you have to save 599 00:45:42,800 --> 00:45:43,190 it. 600 00:45:43,650 --> 00:45:46,550 Let's going to an S any. 601 00:45:46,880 --> 00:45:50,440 Oh let's try trade. 602 00:45:50,760 --> 00:45:54,110 Try it or let's put it together. 603 00:45:54,110 --> 00:45:56,320 Try it save 604 00:46:02,050 --> 00:46:10,530 it copy paste it you know it used to be one in order to get. 605 00:46:11,020 --> 00:46:18,670 Now we are here in this switch this part so we copy it and then it will be done. 606 00:46:18,740 --> 00:46:32,660 We copy and it do to go down again copy it instead of food we eat again look you see this one is for 607 00:46:32,660 --> 00:46:37,880 this is W and from here to E. 608 00:46:38,090 --> 00:46:44,660 This part is as the very one and here is as we do too. 609 00:46:45,050 --> 00:46:50,520 So when I could get a copy again and their weekly form. 610 00:46:50,620 --> 00:47:01,020 So this is to yeah to to in full this one. 611 00:47:01,030 --> 00:47:02,770 Now P.C. tree. 612 00:47:02,920 --> 00:47:09,530 Oh I know a b is 5 and 6. 613 00:47:09,570 --> 00:47:19,760 So this is exactly how we can configure in a sine and nine feet address for each of your devices. 614 00:47:19,830 --> 00:47:21,330 Note that. 615 00:47:21,360 --> 00:47:24,610 Let me check it for you. 616 00:47:25,300 --> 00:47:28,860 Let's say not Let's put it here. 617 00:47:29,060 --> 00:47:38,140 No know that note that the IBM Joyce that we settle for. 618 00:47:38,470 --> 00:47:45,230 Or would there form he we will be represented for us the gateway. 619 00:47:45,350 --> 00:48:00,460 So I mean the f 0 0 0 1 represent for also presents as the gateway Gateway IP. 620 00:48:00,740 --> 00:48:03,060 It would be accurate. 621 00:48:03,310 --> 00:48:09,290 So this is just we will see that we understand how it is. 622 00:48:09,700 --> 00:48:10,300 All right. 623 00:48:10,300 --> 00:48:16,400 So now let's just make a few configurations so it's not difficult at all. 624 00:48:16,640 --> 00:48:19,660 So okay if we go here 625 00:48:23,250 --> 00:48:33,070 we'll do it okay so we can go to see I I make it all we can what exactly. 626 00:48:33,200 --> 00:48:43,910 So here we are in due to freeze again now since we have setting up everything in order everything that 627 00:48:43,910 --> 00:48:46,380 we have done before was okay. 628 00:48:46,400 --> 00:48:49,600 It was alright but chose to avoid any confusion. 629 00:48:49,610 --> 00:48:53,930 And if fruit you or we could go so that you understand exactly what we meant. 630 00:48:53,990 --> 00:49:02,660 So we're going to make those changes that we have made from what we did to these ones. 631 00:49:02,660 --> 00:49:03,190 All right. 632 00:49:03,200 --> 00:49:13,110 So to do so you're going to click on author so you click on it and either you can choose your command 633 00:49:13,170 --> 00:49:19,080 line interface to write it or you can just go to the configuration it's like it's a problem and then 634 00:49:19,170 --> 00:49:21,260 you're going to make some changes. 635 00:49:21,360 --> 00:49:21,960 Okay. 636 00:49:22,020 --> 00:49:23,880 This is all old news. 637 00:49:23,910 --> 00:49:27,460 So we can change this one to two to one. 638 00:49:28,060 --> 00:49:30,380 Okay. 639 00:49:30,450 --> 00:49:31,850 Now what are we going to do. 640 00:49:31,890 --> 00:49:33,980 We are going to see one. 641 00:49:34,050 --> 00:49:34,690 OK. 642 00:49:34,740 --> 00:49:43,780 Now we are going to change the IP Joyce the first Internet IP address to what we have sitting on. 643 00:49:44,070 --> 00:49:45,140 So what was it. 644 00:49:45,150 --> 00:49:48,000 It was 1 1 1. 645 00:49:48,010 --> 00:49:50,110 Okay so no changes they did. 646 00:49:50,110 --> 00:49:52,180 No we put it on. 647 00:49:52,280 --> 00:49:52,840 Perfect. 648 00:49:53,130 --> 00:50:01,710 So now let's go to or senior or silly all of the way to one. 649 00:50:01,710 --> 00:50:07,290 So this earlier was that CEO of order one is two one. 650 00:50:08,000 --> 00:50:10,670 This one is this. 651 00:50:10,740 --> 00:50:12,950 Here two one. 652 00:50:12,960 --> 00:50:13,670 All right. 653 00:50:13,680 --> 00:50:19,350 So when I'm gone I would see your when this changes. 654 00:50:19,390 --> 00:50:21,850 One two. 655 00:50:22,360 --> 00:50:22,850 Okay. 656 00:50:22,870 --> 00:50:27,480 So we put it on on your seat and I. 657 00:50:27,700 --> 00:50:31,030 You should type no shutdown or no shot. 658 00:50:31,060 --> 00:50:31,780 All right. 659 00:50:31,840 --> 00:50:34,840 So since you click on the here. 660 00:50:34,900 --> 00:50:35,920 So that's it. 661 00:50:35,920 --> 00:50:36,820 And then. 662 00:50:36,820 --> 00:50:37,330 Perfect. 663 00:50:37,750 --> 00:50:41,820 So now we can try to do the same thing for we will do a tool. 664 00:50:42,760 --> 00:50:46,790 OK. 665 00:50:47,160 --> 00:50:51,090 So I work toward Twitter to do that. 666 00:50:51,280 --> 00:50:57,130 So Sylvia King is going to want to tool. 667 00:50:57,310 --> 00:50:58,230 But first thing first. 668 00:50:58,300 --> 00:51:06,020 Let's see if we didn't have some some evil mistakes. 669 00:51:06,060 --> 00:51:06,660 Exactly. 670 00:51:06,870 --> 00:51:09,620 So you know here we go. 671 00:51:09,630 --> 00:51:15,070 So this subnet mask should be fully Syrian. 672 00:51:15,350 --> 00:51:21,530 This alternate is this one to 673 00:51:24,270 --> 00:51:24,500 do 674 00:51:27,330 --> 00:51:31,110 two ups. 675 00:51:32,250 --> 00:51:34,100 Let's see how it's set up. 676 00:51:34,190 --> 00:51:34,860 Okay. 677 00:51:34,910 --> 00:51:40,450 All right. 678 00:51:40,730 --> 00:51:44,680 So now we click on water here. 679 00:51:44,950 --> 00:51:46,670 So we go to config. 680 00:51:46,910 --> 00:51:54,190 Why do you see it on so config. 681 00:51:54,850 --> 00:51:58,550 No Hobson then we're going to put it. 682 00:51:58,860 --> 00:52:06,100 Let's put it like a do do do do. 683 00:52:06,760 --> 00:52:11,100 So this is all hostname and first Internet. 684 00:52:11,180 --> 00:52:13,100 What do so here. 685 00:52:13,130 --> 00:52:14,670 Are we going to do the same thing. 686 00:52:15,150 --> 00:52:22,840 Okay so we are in order to do what you do has to do to as IP address to me. 687 00:52:24,230 --> 00:52:25,930 1 Okay. 688 00:52:27,100 --> 00:52:34,830 Great one this is what we have to change tween 1. 689 00:52:35,240 --> 00:52:38,330 This is for first internet of what you do first. 690 00:52:39,430 --> 00:52:45,040 Lexington N.C. war a war of water 2 excellent 2 1 1. 691 00:52:45,230 --> 00:52:53,000 So you must use these 1 good we say later on that means no shutdown. 692 00:52:53,450 --> 00:52:59,050 Right now we're going to go to our senior Jake Dad. 693 00:52:59,750 --> 00:53:04,090 Why would I be a choice of CEO. 694 00:53:04,170 --> 00:53:05,390 What was it. 695 00:53:05,470 --> 00:53:11,260 Sylvia who do two to do that and she needed to hear it like that. 696 00:53:11,510 --> 00:53:15,120 To do that I changed my game. 697 00:53:16,240 --> 00:53:34,000 And so must was what to too deep to sell and included on it was pretty darn it so we can try to move 698 00:53:34,110 --> 00:53:45,120 again read the news on Oh so you can do and you know it's Gigi's one minute it. 699 00:53:45,440 --> 00:53:46,350 It's it's one 700 00:53:49,570 --> 00:53:50,070 on. 701 00:53:50,180 --> 00:54:01,210 Okay so now we've finished zero order is this but now it's time to just configure this one as we did 702 00:54:01,270 --> 00:54:08,130 it earlier but now it should be much this order so that we can try to be quality 703 00:54:10,860 --> 00:54:27,920 in on its own feet as we configure them so here they stole config PCC walls and go on open season. 704 00:54:28,030 --> 00:54:33,310 Obviously she's a war logs 705 00:54:41,080 --> 00:54:42,010 as see it. 706 00:54:42,070 --> 00:54:57,620 All right so IP address of peace war was one six okay so default gateway one one of course is yes it's 707 00:54:57,650 --> 00:54:59,740 one was good. 708 00:55:00,200 --> 00:55:00,730 Yeah. 709 00:55:00,900 --> 00:55:01,290 One on 710 00:55:06,540 --> 00:55:07,570 equality is 711 00:55:10,870 --> 00:55:12,240 all right. 712 00:55:13,880 --> 00:55:15,730 Same thing though. 713 00:55:16,990 --> 00:55:35,570 Can think address of two towards eight. 714 00:55:35,880 --> 00:55:41,680 Let's try to find this one in Mm mm mm mm mm mm mm mm mm. 715 00:55:41,920 --> 00:55:47,660 Well see we didn't put it this easy. 716 00:55:50,510 --> 00:55:55,480 We meet in busted tail light and change it to five 717 00:56:00,580 --> 00:56:09,720 no known to a six year it's been six oh six Oh 718 00:56:12,710 --> 00:56:13,890 yeah. 719 00:56:14,220 --> 00:56:20,610 Oh you is no one one in seven. 720 00:56:20,750 --> 00:56:23,660 It's chicken yeah. 721 00:56:23,710 --> 00:56:39,700 It's even so still you say one 7 x let's go. 722 00:56:40,330 --> 00:56:42,260 So you do the same thing. 723 00:56:42,310 --> 00:56:49,980 You still confirming and being poor. 724 00:56:50,090 --> 00:57:12,920 You see food see who was 6 2 6 we got six eggs cause in here they stole configure. 725 00:57:14,080 --> 00:57:17,040 You see Queen was funny 726 00:57:21,860 --> 00:57:22,920 to do it. 727 00:57:25,910 --> 00:57:27,470 Here you go. 728 00:57:28,110 -->

740 00:57:57,740 --> 00:58:01,670 The war is due 1 6. 741 00:58:01,690 --> 00:58:02,000 Okay. 742 00:58:02,040 --> 00:58:04,200 Perfect score. 743 00:58:04,280 --> 00:58:05,820 I'll close. 744 00:58:06,210 --> 00:58:07,550 Close. 745 00:58:07,680 --> 00:58:13,830 You see one is wanted in this one once again. 746 00:58:13,980 --> 00:58:15,760 Let's check in once proof. 747 00:58:18,030 --> 00:58:21,510 You see 2 is 1 8 2 8 748 00:58:25,050 --> 00:58:26,700 1 8. 749 00:58:26,960 --> 00:58:29,120 Default Wait wait wait. 750 00:58:29,200 --> 00:58:30,030 1 1. 751 00:58:30,230 --> 00:58:32,900 Good game. 752 00:58:32,940 --> 00:58:48,730 Now you see for all of these you see for 3 6 6 2 6 different gateway or no no. 753 00:58:49,190 --> 00:58:55,640 If one gateway is 2 1 the same as the order. 754 00:58:57,950 --> 00:58:58,570 6. 755 00:58:58,770 --> 00:59:04,280 Okay okay 2 1 2 1. 756 00:59:04,470 --> 00:59:08,050 Say so. 757 00:59:08,390 --> 00:59:15,220 Check it again see you get to 1 before you gateways. 758 00:59:17,320 --> 00:59:25,620 So this one now for me to be tied to 1. 759 00:59:26,520 --> 00:59:30,990 Okay so now the Constitution is complete. 760 00:59:31,080 --> 00:59:41,340 We can try no 2 2 test or picture or network by clicking on this message icon and from here to here 761 00:59:42,170 --> 00:59:43,980 you have to check this. 762 00:59:44,040 --> 00:59:49,770 I want to see if it's successful it is what let's delete it so that we can try again that we can see 763 00:59:50,730 --> 00:59:56,450 again from this computer this computer successful IT STRAIGHT. 764 59:56.460 --> 1:00:01.980 NOW THIS COMPUTER again because we have made in the configuration guys. 765 1:00:02.040 --> 1:00:04.580 So that's why we check it again and again. 766 1:00:05.040 --> 1:00:14.330 And in these two here obviously successful and and is to do it you know because it isn't there would 767 1:00:14.690 --> 1:00:15.170 fail. 768 1:00:15.330 --> 1:00:17.730 All right so so far so good from now. 769 1:00:17.930 --> 1:00:23.510 So we're going to just have to configure the IP world so let's try these first. 770 1:00:23.530 --> 1:00:24.930 The last name. 771 1:00:27.370 --> 1:00:33.360 It was B so this is one and one time here too. 772 1:00:33.380 --> 1:00:37.320 It shouldn't be success one should we find it. 773 1:00:37.380 --> 1:00:37.740 OK. 774 1:00:37.770 --> 1:00:39.750 Delete them OK now. 775 1:00:39.930 --> 1:00:47.150 Now then the task is we have to make your way so that we we see 2 Disorder. 776 1:00:47.150 --> 1:00:49.880 Hey your wallet. 777 1:00:50.160 --> 1:00:55.230 So in that you send the weakest of the messages or the connection to here. 778 1:00:55.270 --> 1:00:57.580 It must be this way. 779 1:00:57.610 --> 1:01:06.700 Well as we have seen earlier because we don't set it up the IP world off of this network. 780 1:01:06.910 --> 1:01:16.090 So if this computer cannot reach this computer so it can just only be here and be here and from here 781 1:01:16.120 --> 1:01:18.330 to here from here to here. 782 1:01:18.340 --> 1:01:21.850 But they get close because they don't know yet they won't. 783 1:01:21.850 --> 1:01:25.430 So as we have seen that weed control squeak. 784 1:01:25.570 --> 1:01:35.260 Or it was already just click here and well we can even see fate so well now we're going to configure 785 1:01:35.330 --> 1:01:35.890 it. 786 1:01:35.890 --> 1:01:38.560 So what we can do it's deleted. 787 1:01:38.770 --> 1:01:45.050 We have to go to war to one and we have to say to him hey you know what man. 788 1:01:45.370 --> 1:01:49.480 I want to go to this destination. 789 1:01:49.480 --> 1:01:53.560 Please make some house so that we can go to it. 790 1:01:53.830 --> 1:02:00.810 So we are in configuration mode so we can take AP Road and stick it out again. 791 1:02:00.830 --> 1:02:01.230 Okay. 792 1:02:01.270 --> 1:02:02.650 And Cupid comments on it. 793 1:02:02.910 --> 1:02:06.450 That means that we are in a good path of tuna. 794 1:02:06.520 --> 1:02:10.880 So we take AP World and then where we want to go. 795 1:02:11.170 --> 1:02:16.790 We want to go to D to a distant network. 796 1:02:16.840 --> 1:02:23.320 So we did did this scene or disconnect with is the network is is the is the third one. 797 1:02:23.350 --> 1:02:25.590 This one is the third one so too easy. 798 1:02:26.080 --> 1:02:29.390 So we're going to stay or we just copy first. 799 1:02:29.490 --> 1:02:44.200 I had it before or wide to zero and then did subnet was 255 255 255 and easy war and clear but we we 800 1:02:44.200 --> 1:02:47.620 need to go to disagree Ah. 801 1:02:47.680 --> 1:02:49.820 So this number was 4. 802 1:02:49.840 --> 1:02:51.370 So we are off to 2. 803 1:02:51.700 --> 1:02:55.630 So euro food 2 was 2 1 not 2 2. 804 1:02:55.630 --> 1:03:02.080 So we placed this again to do and we have to take 2 and then 2. 805 1:03:02.620 --> 1:03:09.080 So now 10 percent of Excel and so where you are now we are really doing the same thing for the water 806 1:03:09.090 --> 1:03:10.280 tool. 807 1:03:10.470 --> 1:03:11.190 Okay. 808 1:03:11.300 --> 1:03:11.980 Close it. 809 1:03:13.060 --> 1:03:13.480 Okay. 810 1:03:13.480 --> 1:03:15.030 Now we click on this will do now. 811 1:03:16.600 --> 1:03:20.040 Creek and we'll go to sea. 812 1:03:20.130 --> 1:03:28.890 I was endure a so that we go to the canoe so that we go to the global configuration. 813 1:03:28.890 --> 1:03:32.960 We take a finger on a finger in case. 814 1:03:32.960 --> 1:03:33.860 Well now we are here. 815 1:03:33.900 --> 1:03:35.230 Now we can contribute. 816 1:03:35.760 --> 1:03:41.340 Now when we are in water to here we need to go to this network. 817 1:03:41.340 --> 1:03:46.920 So we take IP world IP wood and then this network. 818 1:03:46.920 --> 1:03:52.860 This network is so we can just pass it again first instead of one. 819 1:03:52.980 --> 1:03:57.450 It will be one dud. 820 1:03:57.770 --> 1:03:58.860 Zero. 821 1:03:58.900 --> 1:04:01.740 So okay let's check it. 822 1:04:01.860 --> 1:04:03.460 Network 1 0. 823 1:04:03.480 --> 1:04:04.890 Network was 1 0. 824 1:04:04.890 --> 1:04:05.380 Perfect. 825 1:04:05.410 --> 1:04:06.460 Excellent. 826 1:04:06.510 --> 1:04:14.520 So now we want to put the subnet to 5 5 as it was into 1 2 5 5 2 5 5 5 5. 827 1:04:14.520 --> 1:04:16.960 Do not do that as war. 828 1:04:17.380 --> 1:04:24.190 And we are going to since we are here in the world at all we are going to groups to disillusion this 829 1:04:24.190 --> 1:04:25.580 scenario of 4. 830 1:04:25.620 --> 1:04:29.850 One was what it was 2 1. 831 1:04:29.850 --> 1:04:32.000 Okay so now let's just copy. 832 1:04:32.040 --> 1:04:37.080 Let's just play it again and just more if it is 1 2. 833 1:04:37.450 --> 1:04:38.710 Okay now we can present them. 834 1:04:39.190 --> 1:04:44.590 So now your your network must be able to be connected. 835 1:04:44.610 --> 1:04:47.840 So let's close it and got to trade outward. 836 1:04:47.880 --> 1:04:50.180 All right all right. 837 1:04:50.190 --> 1:04:59.850 Now if everything was done properly quickly as we have changed or step by step process we made them 838 1:04:59.940 --> 1:05:07.140 in order so that you understand where is the IP one what is the IP what is there before 6 7 8 and so 839 1:05:07.140 --> 1:05:07.560 on. 840 1:05:07.560 --> 1:05:16.580 So as usual we start from the water then we take the bass as the water it is someone rebranded to see 841 1:05:16.590 --> 1:05:24.330 war and then the next coalition is won the next coalition is 2 3 4 and stuff in stuff like that and 842 1:05:24.370 --> 1:05:25.230 going on. 843 1:05:25.560 --> 1:05:26.640 So that's how we made it. 844 1:05:26.670 --> 1:05:33.220 So now let's let's send a message from the world to what we know to one. 845 1:05:33.300 --> 1:05:39.660 I mean the first B.C. he would click here. 846 1:05:41.070 --> 1:05:43.450 And now we're going to try to say it. 847 1:05:43.920 --> 1:05:46.260 Let's see if you wanna see you 848 1:05:49.290 --> 1:05:51.020 click successful. 849 1:05:51.090 --> 1:05:52.110 Excellent. 850 1:05:52.110 --> 1:05:52.820 Let's try. 851 1:05:52.820 --> 1:05:55.320 Phone on the phone. 852 1:05:55.350 --> 1:05:56.850 Busy too. 853 1:05:57.000 --> 1:06:00.430 And let me put it you know Excel and again. 854 1:06:00.460 --> 1:06:04.090 So now let's meet the communication in reverse. 855 1:06:04.090 --> 1:06:04.960 Obviously. 856 1:06:05.420 --> 1:06:08.800 Let's see if you see one successful exam. 857 1:06:08.840 --> 1:06:10.300 So this is how it works. 858 1:06:10.370 --> 1:06:19.520 So if you want you can go to simulation and you can just get started so that you see how the progress 859 1:06:20.390 --> 1:06:21.110 is made. 860 1:06:21.110 --> 1:06:22.910 You know just wait a little bit. 861 1:06:23.360 --> 1:06:24.080 That's it. 862 1:06:24.200 --> 1:06:33.890 But okay now what if I want to put a password on my order to put passwords so that if you want to paying 863 1:06:33.920 --> 1:06:36.810 someone if you want to go you have to try. 864 1:06:37.100 --> 1:06:38.890 You have to know the password. 865 1:06:38.920 --> 1:06:45.270 So now it's secure or network but before that we are going to show you how you can just ping them in 866 1:06:45.300 --> 1:06:45.980 a timely note. 867 1:06:46.010 --> 1:06:47.730 So yeah. 868 1:06:47.830 --> 1:06:48.190 All right. 869 1:06:48.640 --> 1:06:49.180 All right. 870 1:06:49.180 --> 1:07:01.110 So now we can try to just been one of these computers it's here league and stop common bond so let's 871 1:07:01.230 --> 1:07:10.390 say that we will not try to B know which one okay one this is more easy. 872 1:07:10.760 --> 1:07:11.290 Easy one. 873 1:07:11.300 --> 1:07:15.040 OK. 874 1:07:15.320 --> 1:07:25.190 1 9 2 1 1 6 8 1 1 7. 875 1:07:25.270 --> 1:07:30.050 All right okay. 876 1:07:30.140 --> 1:07:31.010 The connection is made. 877 1:07:31.020 --> 1:07:36.930 It's not it's tried to to being b 878 1:07:41.410 --> 1:07:45.950 0 3 5 879 1:07:55.230 --> 1:07:56.660 0 right. 880 1:07:56.730 --> 1:08:00.290 So it is connected to it. 881 1:08:00.360 --> 1:08:05.940 So let's try again because we think that it is time you know we just a mistake. 882 1:08:06.020 --> 1:08:06.960 Okay. 883 1:08:07.050 --> 1:08:08.430 It is okay. 884 1:08:08.730 --> 1:08:15.540 So we can try to being P.C. for it's a and now. 885 1:08:15.540 --> 1:08:16.080 All right. 886 1:08:16.110 --> 1:08:18.210 So this is how it works. 887 1:08:18.300 --> 1:08:24.900 So now we are going to to empower or network I mean to secure it. 888 1:08:24.990 --> 1:08:33.180 So because when your network is opened to any kind of computers it's in that way of course it's in central 889 1:08:33.180 --> 1:08:33.540 core. 890 1:08:33.570 --> 1:08:38.180 So we have seen you know this IP address so that the network knows about them. 891 1:08:38.190 --> 1:08:46.200 But what happens if an attacker added his computer and configure it exactly the same way. 892 1:08:46.320 --> 1:08:48.670 Of course you're going to get the communication too. 893 1:08:49.200 --> 1:08:49.780 OK. 894 1:08:49.800 --> 1:08:55.640 So we have to secure or network so get sick you need.
