WEBVTT 00:09.110 --> 00:10.680 Offense will come back. 00:10.700 --> 00:14.780 Now it's time to install and configure your own DNS server. 00:15.230 --> 00:18.360 In our previous lesson we learned the tropical part of it. 00:18.560 --> 00:24.120 Now in this lesson I'm going to show you how to install configure and do your own DNS server. 00:24.280 --> 00:24.760 OK. 00:24.890 --> 00:26.590 So let's see practically. 00:26.780 --> 00:27.210 OK. 00:27.320 --> 00:33.630 There are a number of things that you need to do in order to install your own DNS servers successfully. 00:33.950 --> 00:39.650 OK so first of all you need to install the package OK which is necessary for a DNS server. 00:39.650 --> 00:43.430 So I'm going to show the whole install by nine. 00:43.460 --> 00:46.680 OK it is world famous your DNS software package. 00:46.700 --> 00:52.360 Ok so to install lact just do Sudipta Kate install by nine. 00:52.700 --> 00:57.160 Ok this will install the Byne package on your server. 00:57.470 --> 00:57.890 OK. 00:58.100 --> 01:03.350 And after installation of this you need to set up static IP address hoki. 01:03.440 --> 01:09.650 If you are really hearing static IP address please send the static IP address according to did set things 01:09.690 --> 01:12.030 OK and remove any extrinsically. 01:12.110 --> 01:18.680 OK so far that just opens a clock faces. 01:18.680 --> 01:19.170 OK. 01:19.210 --> 01:20.980 Check out the settings. 01:21.050 --> 01:25.050 Set everything correctly according to the settings. 01:25.240 --> 01:30.370 OK of setting up your own static IP address. 01:30.380 --> 01:34.570 The third thing that we need to do is we need set up our own. 01:34.990 --> 01:37.650 And that is fully qualified domain name. 01:37.760 --> 01:38.320 OK. 01:38.630 --> 01:41.830 And for that you need to know your host name. 01:41.870 --> 01:45.020 So just type the command hostname. 01:45.070 --> 01:46.690 This is my current host name. 01:46.940 --> 01:54.770 You can see your current hostname with this command to set up your own skilly and just open all the 01:55.340 --> 01:58.910 PC ports here. 01:59.060 --> 02:03.970 What you need to do is just come into this line here. 02:04.040 --> 02:08.870 What is most striking libraries 10.0 dot dot 16. 02:09.200 --> 02:09.860 OK. 02:10.130 --> 02:14.770 And here you need to sort of force the hostname code of light. 02:14.910 --> 02:21.060 It is the current hostname and I want to set up a domain name called off line dot com. 02:21.200 --> 02:28.440 OK you can set up any domain that you want but the format is same that means you need to stick to hostname 02:28.510 --> 02:30.790 and Dogon could last longer. 02:31.120 --> 02:31.720 OK. 02:31.920 --> 02:47.600 Of this again hostname sort of like this is over 2D and via certain god you got 16 years of phone call. 02:48.110 --> 02:48.780 OK. 02:51.410 --> 02:59.620 OK after writing this bestower hostname and of Goudey and stuff Gideon just type f and here you can 02:59.620 --> 03:02.150 see code off line got cut off line dot com. 03:02.180 --> 03:04.280 Now it is out of Guderian. 03:04.420 --> 03:05.080 OK. 03:05.660 --> 03:11.490 So the next thing that you need to do is you need to set up this DNS server. 03:11.690 --> 03:14.050 Ok as you were DNS server. 03:14.330 --> 03:14.660 OK. 03:14.660 --> 03:18.300 So for that what you need to do is just open the file. 03:18.390 --> 03:21.530 It is the result of gone. 03:22.130 --> 03:22.370 OK. 03:22.370 --> 03:26.780 Here you can see this is the good DNS server. 03:26.790 --> 03:34.010 So comment on this and here just type name so and add your own names over here. 03:34.060 --> 03:42.820 You got 16 and then each each line dot com. 03:43.120 --> 03:44.150 OK. 03:44.440 --> 03:44.690 Good. 03:44.740 --> 03:48.220 This is right this data. 03:48.310 --> 03:48.780 OK. 03:48.790 --> 03:55.430 Now if the setting does DNS so the next thing you need to do is you need to add forwarders means in 03:55.470 --> 04:01.410 case you set or fail to respond to a query then that queries transferred to forwards. 04:01.430 --> 04:09.870 OK so here I'm going to send Congress public DNS so as forwarder to get so sick forwarders unit to go 04:11.370 --> 04:17.820 see mine yes and he said you need to do the file name call option. 04:17.860 --> 04:18.980 So slow. 04:19.260 --> 04:23.800 I got one got options. 04:24.210 --> 04:31.060 OK here you need to remove these comment lines here. 04:31.610 --> 04:32.050 You are. 04:32.100 --> 04:36.320 Own forward us you can set up the IP addresses. 04:36.450 --> 04:40.670 And according to gyse but I like Google's public Dionysos 04:45.310 --> 04:49.960 it got a lot for not for. 04:51.270 --> 04:57.690 I did the forwarders and now it's time to test our followers again. 04:57.850 --> 05:01.810 So for that just restart your DNA. 05:01.810 --> 05:08.130 So so far that is my nine restart 05:10.970 --> 05:12.010 OK. 05:13.160 --> 05:16.400 Clear this green will get this day forward. 05:16.400 --> 05:26.270 So just to be able to not call OK now here you can see a time in millisecond skeery time and again the 05:26.270 --> 05:28.020 same domain. 05:28.550 --> 05:32.980 OK now the time is reduced to just milliseconds. 05:33.120 --> 05:36.820 OK so all four of those are working correctly here. 05:36.830 --> 05:40.180 Again the meaning of it is that. 05:40.630 --> 05:46.270 So after adding the forwarders notes time to carry it forward and we will look zone. 05:46.530 --> 05:50.690 OK so you cleared that you just need to go. 05:50.710 --> 05:56.240 It is mine and you need to open the file name back call the local. 05:56.370 --> 05:56.850 OK. 05:57.200 --> 06:03.390 So you just open that pseudo name. 06:04.750 --> 06:13.040 And here we're going to add the zone information or you can see me going on hear the zone names with 06:13.150 --> 06:14.420 the file locations. 06:14.480 --> 06:19.250 So you can create any zone according to your domain here. 06:19.520 --> 06:25.920 Just type of line dot com 06:29.620 --> 06:39.850 get in today's paper our paper is mustardy And so we're primarily and so on here you know the database 06:39.850 --> 06:43.290 location OK the zone database location. 06:43.300 --> 06:52.940 So file it is the vine just Callier of line Gocong got divi OK. 06:52.960 --> 06:55.220 This file is not present there currently. 06:55.280 --> 06:57.700 Are we going to create that file. 06:58.090 --> 06:58.500 OK. 06:58.540 --> 07:03.440 At this location and add the data according to our current settings. 07:03.530 --> 07:06.360 OK. 07:06.790 --> 07:10.740 Now this is the forward Likud's on ugly and I've put this forward lookup. 07:10.750 --> 07:13.600 So you just created he was absorbed. 07:13.740 --> 07:19.030 Agreed that he was Look-Up zone uniquely will see what I purchase like this. 07:19.060 --> 07:22.910 That is to dot zero dot. 07:23.160 --> 07:27.010 Then again you need to set your IP address in three words zone. 07:27.010 --> 07:43.920 In this way and in Italy are not a be and hear it again five Mosteller say location. 07:44.800 --> 07:55.690 It is the vine and here for me was file with a name it adds dot and OK you can name your database file 07:55.700 --> 07:57.260 what you want. 07:57.340 --> 07:59.710 It has nothing to do with your domain name. 07:59.850 --> 08:00.440 OK. 08:00.670 --> 08:05.810 So after writing this forward and we will look zone this. 08:05.930 --> 08:06.350 Right. 08:06.350 --> 08:07.310 Really good. 08:07.420 --> 08:08.060 OK. 08:08.120 --> 08:11.040 And now it's time to create our database files. 08:11.230 --> 08:14.230 So far that you create the file. 08:14.320 --> 08:16.590 I'm going to just copy here. 08:16.750 --> 08:20.300 I'm going to copy the DBI doc local file. 08:20.380 --> 08:21.040 OK. 08:21.420 --> 08:24.410 And just what EDV got the local 08:27.140 --> 08:34.480 quote off line because I'm not the we just do this with Sudol. 08:35.470 --> 08:38.550 OK wireman copying this because our. 08:38.620 --> 08:44.080 I'm OK our the time to have some information. 08:44.080 --> 08:48.540 So often this is pseudo why it did or did it I was fine. 08:48.580 --> 08:49.200 OK. 08:49.750 --> 08:56.840 So just start to insert a little bit of this here. 08:56.890 --> 09:02.830 You need to replace this localhost with our current domain. 09:03.090 --> 09:03.490 OK. 09:03.550 --> 09:05.930 So this guy called off the line. 09:05.940 --> 09:12.360 He said they couldn't call of thing got called off line dot com. 09:12.400 --> 09:17.380 And at the end had to get that dog group. 09:17.550 --> 09:23.670 OK and then here again rubab called off line. 09:26.940 --> 09:36.280 It this route got called off and come will be the Serwer our mail server for this zone our domain and 09:36.550 --> 09:38.230 this is the SUV. 09:38.390 --> 09:38.880 OK. 09:39.130 --> 09:43.300 And here you can see this DTL. 09:43.780 --> 09:47.520 You can see this deal according to your choice. 09:47.530 --> 09:52.620 OK here the serial number the serial number should be changed. 09:52.620 --> 09:52.890 OK. 09:52.960 --> 09:59.680 According to the zone I mean so when you create Nexus zone for another moment then this serial number 09:59.680 --> 10:03.880 should be increased by one or all you can said what do you want. 10:03.880 --> 10:05.920 But this should not be the same. 10:06.040 --> 10:06.330 OK. 10:06.340 --> 10:07.780 This is the refresh rate. 10:07.960 --> 10:11.080 This is retrack expire he needed to catch DTL. 10:11.130 --> 10:11.440 OK. 10:11.650 --> 10:13.910 All the settings are for the war zone. 10:13.990 --> 10:14.390 OK. 10:14.500 --> 10:17.450 This is the refresh rate for an expiry date. 10:17.470 --> 10:17.810 OK. 10:17.830 --> 10:20.700 All this information for you on. 10:21.080 --> 10:21.780 Here. 10:22.210 --> 10:28.500 What you need to do is you need to be addressed in order to got to got 16. 10:29.410 --> 10:35.910 And here early or only four or three lines of code. 10:35.950 --> 10:47.650 And at the end of the loop and here w w d you recall if what I agree Souci that we have learned in the 10:47.650 --> 10:55.820 previous lesson different records and loans you know to got 60 to get the first recall here is antithetical. 10:55.860 --> 10:57.350 We are winning here. 10:57.450 --> 11:08.040 Gura of course and this can be this W.W. means it is a web server of this sort I don't do it. 11:08.720 --> 11:09.430 OK. 11:09.790 --> 11:16.200 Now after writing this data the next thing we need to do is we need to create a database for lookup 11:16.200 --> 11:17.140 zone. 11:17.200 --> 11:26.440 So for that not this time copied the code of number com got DBI to deal with Doc and because we have 11:26.450 --> 11:30.080 said this name in Plaut forward look observe and file. 11:30.280 --> 11:33.760 So we just copied pogey and opened 11:38.790 --> 11:39.380 OK. 11:39.660 --> 11:43.740 No he had to make some changes. 11:46.180 --> 11:54.020 OK here's what you need to do is replace this android with your IP address and. 11:54.150 --> 11:58.140 16 is the end of day IP of this machine. 11:58.800 --> 12:02.280 And here just replace it as 12:06.620 --> 12:13.130 well out of line on is this PDA. 12:13.160 --> 12:14.680 That is the point record. 12:14.840 --> 12:19.760 It is used for a reverse lookup zone and in his foreign names there were no good. 12:20.030 --> 12:24.010 No just run down this tape. 12:26.210 --> 12:27.640 Clear. 12:28.070 --> 12:29.360 Now what do you need to do. 12:29.390 --> 12:35.010 So this by nine days start 12:39.650 --> 12:42.720 it takes Koslov. 12:43.690 --> 12:44.140 OK. 12:44.150 --> 12:49.220 Here you can see our bind 9 service is back and running again. 12:49.400 --> 12:53.640 So good looking forward lookup Zaur look observe. 12:53.840 --> 12:56.210 We have a database for it. 12:56.270 --> 12:56.790 OK. 12:56.990 --> 13:02.200 And after that now it's time to check all our DNS server. 13:02.450 --> 13:03.040 OK. 13:03.490 --> 13:07.930 So instead I'm going to do this look up windows so. 13:08.360 --> 13:08.890 OK. 13:09.150 --> 13:11.050 So look at that. 13:11.130 --> 13:17.460 I equal any I'm going to test any record and we've already learned how to block with the DNS so. 13:17.510 --> 13:17.900 OK. 13:17.990 --> 13:21.330 So just to sort of like go home. 13:21.560 --> 13:22.110 OK. 13:22.250 --> 13:32.690 I know it's ruling elite here or that we how it now good was look up Guri just type IP address. 13:32.960 --> 13:33.280 OK. 13:33.410 --> 13:34.450 Like this. 13:34.700 --> 13:35.390 OK. 13:35.410 --> 13:44.060 Now this means we have successfully configured our DNS server OK how this coalition is successful in 13:44.060 --> 13:46.960 this field you can create your own DNS server. 13:47.030 --> 13:53.270 You can use Cornie we're a local network if you want to make it public like Google's DNS server you 13:53.270 --> 13:56.000 need to register them online. 13:56.120 --> 13:56.420 Maggie.
