1 00:00:00,300 --> 00:00:04,530 So, guys, this lecture is going to be very interesting because in this lecture we are going to change 2 00:00:04,530 --> 00:00:05,880 some network information. 3 00:00:06,480 --> 00:00:13,050 OK, so being able to change your IP address and other network information is a useful skill because 4 00:00:13,050 --> 00:00:18,690 it will help you to access other networks while appearing as a trusted device on those networks. 5 00:00:19,080 --> 00:00:26,610 So, for example, in denial of service attack, you can spoof your IP so that the attack appears to 6 00:00:26,610 --> 00:00:28,030 come from another source. 7 00:00:28,530 --> 00:00:33,630 So simply does helping you invade an IP captain and doing forensic analysis. 8 00:00:33,660 --> 00:00:38,820 So this is relatively simple task in Linux and it is done with the IF config command. 9 00:00:39,300 --> 00:00:42,900 So first of all, we are going to learn how to change the IP address. 10 00:00:42,940 --> 00:00:48,810 OK, so before going to gene IP address, let's check what is the current IP address of this particular 11 00:00:49,110 --> 00:00:50,820 interface that is at zero. 12 00:00:50,820 --> 00:00:53,770 So current IP addresses tend towards zero or 2.8. 13 00:00:54,240 --> 00:00:56,100 So this is IP address that we have here. 14 00:00:56,460 --> 00:01:01,100 OK, so to change your IP address, simply enter if config. 15 00:01:01,110 --> 00:01:01,680 Come on. 16 00:01:01,920 --> 00:01:07,230 Followed by interface you want to represent and the new IP address you want to assign to that interface. 17 00:01:07,530 --> 00:01:09,690 OK, so now let's clear this. 18 00:01:10,630 --> 00:01:12,720 OK, if confect come on. 19 00:01:13,290 --> 00:01:20,320 Followed by the interface that is at zero and then the IP address that you want to allow to it. 20 00:01:20,340 --> 00:01:24,790 So I want to alert 192 one sixty eight one eight one like one one five. 21 00:01:24,810 --> 00:01:26,230 So this is I better than I want to. 22 00:01:26,920 --> 00:01:29,040 OK, so when you do this correctly. 23 00:01:30,560 --> 00:01:32,230 OK, operations, operations are. 24 00:01:32,630 --> 00:01:36,420 OK, so currently we are not the router user, we are not the road user. 25 00:01:36,440 --> 00:01:39,920 That is why we need to add sudo and the starting, OK? 26 00:01:43,590 --> 00:01:49,610 Pseudo now suit will ask for a password, simply give password Karley and enter softly enter. 27 00:01:49,680 --> 00:01:55,750 If you've done everything correctly, then clinics will simply return the command prompt and say nothing. 28 00:01:56,040 --> 00:01:57,200 So this is a good thing. 29 00:01:57,810 --> 00:02:02,640 OK, so when you simply agentic your network connection with if config. 30 00:02:04,900 --> 00:02:15,070 So here you can check that your I.P. address is now changed, which is 192 168 dot a one eight one one 31 00:02:15,070 --> 00:02:17,770 one five, which is same as this one. 32 00:02:17,800 --> 00:02:20,230 OK, so this is how you can change the iapetus. 33 00:02:20,260 --> 00:02:22,390 Now it's time to see how to change them. 34 00:02:22,660 --> 00:02:25,890 Net mosquitoes, which is here, and the broadcast. 35 00:02:26,200 --> 00:02:31,090 So you need to check what does the network and what does the broadcasters does that we have here? 36 00:02:31,120 --> 00:02:36,040 OK, so now let's learn how we can change both of these addresses. 37 00:02:36,310 --> 00:02:43,600 OK, so first of all, clear this and in order to change, but this particular addresses, you need 38 00:02:43,600 --> 00:02:49,360 to again use if config followed by the interface, which is at zero. 39 00:02:52,030 --> 00:03:01,510 IP address, this is IP doesn't simply net mass, so which is very easy to change and give the new net 40 00:03:01,510 --> 00:03:02,440 MUSKETT dressier. 41 00:03:04,050 --> 00:03:10,170 So this was a new address, and if you want to change the broadcast address and simply type broadcast 42 00:03:11,550 --> 00:03:16,920 followed with the new address, which is 190, 160, it got five. 43 00:03:19,340 --> 00:03:23,440 So this is a dessert I want to allot, OK, simple and soft. 44 00:03:23,690 --> 00:03:25,670 And as you can see, that this is not permitted. 45 00:03:25,700 --> 00:03:30,430 OK, so how you can do it, you are very smart. 46 00:03:30,440 --> 00:03:33,740 Now you all know how to do it simply at pseudo. 47 00:03:35,840 --> 00:03:37,940 Enter now, galley's. 48 00:03:39,020 --> 00:03:40,170 Is doing nothing here. 49 00:03:40,640 --> 00:03:43,340 So this means that everything is being changed. 50 00:03:43,460 --> 00:03:50,150 OK, so now let's type if config and hit enter soft hitting enter. 51 00:03:50,750 --> 00:03:57,110 You can check the I.P. address that we have here is 192 168 dot one eight one dot. 52 00:03:57,110 --> 00:03:57,590 WOMAN five. 53 00:03:57,830 --> 00:03:59,240 Yes, it is correct. 54 00:03:59,270 --> 00:04:01,730 OK, then let's check Namaskar address. 55 00:04:02,030 --> 00:04:02,410 OK. 56 00:04:02,970 --> 00:04:07,850 Earlier it was something else, but this time it is having two five 5.5. 57 00:04:08,320 --> 00:04:09,170 Was it a dot one. 58 00:04:09,620 --> 00:04:11,810 And then let's shake broadcasters. 59 00:04:11,900 --> 00:04:14,140 So broadcaster does this again see. 60 00:04:14,540 --> 00:04:19,730 So this is how you can change the network information using if conflict. 61 00:04:19,730 --> 00:04:24,350 Come on in the next lecture we are going to see how to spoof your Mac address. 62 00:04:24,950 --> 00:04:28,830 So it will be going to very interesting how to change your Mac address. 63 00:04:29,060 --> 00:04:30,740 OK, so this is all for this lecture. 64 00:04:30,740 --> 00:04:31,030 This.
