WEBVTT 00:00.210 --> 00:06.720 So the second step is to install Colly well, since we'll use the oveI file it, it'd be better to say 00:06.750 --> 00:08.070 import for this step. 00:09.010 --> 00:16.520 And the downloads finished it under the download folder, now I'll open a virtual box interface Chew's 00:16.540 --> 00:17.110 import. 00:18.210 --> 00:23.490 And choose the OVA file under the download folder and click continue. 00:25.440 --> 00:31.200 So as you can see, there are the suggested settings of virtual box for the imported virtual machine. 00:32.590 --> 00:34.540 RAM is two gigs by default. 00:36.330 --> 00:41.280 Now, just click import and agree to the license agreement in order to continue. 00:45.510 --> 00:51.990 And it starts to import it may take a couple of minutes, so I want to look at the size of the empty 00:51.990 --> 00:53.580 space on my host. 00:56.950 --> 01:05.350 D.F. Command simply displays the free disk space and Dash eight parameter makes the result human readable. 01:06.370 --> 01:12.610 Now I have 140 gigabytes of free space, and that should be plenty for this installation. 01:23.450 --> 01:30.500 Installations finished and this is a summary of the VM ram is two gigabytes by default. 01:31.520 --> 01:35.430 And if you have enough ram on your whole system, I suggest you increase it. 01:36.650 --> 01:39.110 Networking is not just as I want. 01:40.860 --> 01:42.540 Now, just click on the start button. 01:44.310 --> 01:51.180 OK, the virtual machine could not be started, so I wonder about the details of this error, don't 01:51.180 --> 01:51.390 you? 01:52.870 --> 02:00.460 OK, then, so to fix this problem, we'll need to install the Oracle VM virtual box extension back. 02:01.550 --> 02:05.390 So I copy this part and I'll just search on the Web. 02:07.000 --> 02:10.390 So now let's look at the official site of Virtual Box. 02:12.010 --> 02:16.870 We can download it under the title of Oracle, the virtual Xbox Extension PAC. 02:18.340 --> 02:20.800 The oldest click on this link and say the file. 02:22.440 --> 02:23.970 And it quickly downloads. 02:25.930 --> 02:28.120 So let's open the file and click install. 02:30.310 --> 02:35.800 And again, I'll accept the virtual license agreement and finally enter the password to complete the 02:35.800 --> 02:36.520 installation. 02:40.670 --> 02:42.770 And now it's been installed successfully. 02:44.430 --> 02:49.650 So now I'd like to go to the preferences and double check the extension packages. 02:53.590 --> 02:57.900 And everything is OK, good, so now we can start again. 03:02.750 --> 03:05.840 OK, so our county is booting for the first time. 03:07.070 --> 03:10.220 Click switch for the full screen mode. 03:18.870 --> 03:20.910 And here we are at the login screen. 03:21.920 --> 03:27.350 Now, in addition to the changes that I mentioned in the previous lecture, there is another important 03:27.350 --> 03:36.320 change in this county 2020 to release the default user account is now a standard unprivileged user. 03:37.190 --> 03:41.500 Caleigh is no longer using the super user account route by default. 03:42.290 --> 03:42.560 Right. 03:42.950 --> 03:47.660 So the new default credentials are Kelly and Co.. 03:51.860 --> 03:55.010 And welcome to Khaleed 2020, not to. 03:56.450 --> 04:02.270 Now, normally, the screen resolution automatically fits your particular screen, but if you have any 04:02.270 --> 04:08.720 resolution problems like I appear to be having, you can change the scale for your screen. 04:09.560 --> 04:12.830 So first, I'll just open up the display settings. 04:14.980 --> 04:21.790 And I can choose the resolution value to be 1920 by twelve hundred and click the apply button. 04:25.660 --> 04:26.800 Now go to preferences. 04:27.680 --> 04:31.460 And under the display tab, you can change the scale factor. 04:32.470 --> 04:35.980 It's also had this value to be 90 percent of my screen. 04:36.950 --> 04:41.330 And you can change it whatever you want and just try different values for your screen. 04:42.440 --> 04:45.800 All right, so I'll click, OK, now let's look at the changes. 04:53.600 --> 04:54.730 Yeah, that's pretty good. 04:59.590 --> 05:03.130 So let's open a terminal screen and check the network connection. 05:05.670 --> 05:12.250 When I run the if config command with standard user privileges, I will get an error because they have 05:12.270 --> 05:16.950 config command is under the Espin folder and requires route privileges. 05:18.040 --> 05:20.790 So why don't we have a look inside that has been folder. 05:22.670 --> 05:30.380 As you can see, I can run this CD, TWD and Alaska commands without pseudo, these commands do not 05:30.380 --> 05:31.990 require privileges. 05:32.690 --> 05:36.620 However, their commands that are under the SBN folder must be run with pseudo. 05:37.480 --> 05:38.560 If config is here. 05:39.670 --> 05:41.590 And let's run this command with pseudo. 05:47.660 --> 05:48.740 And it's OK now. 05:50.640 --> 05:53.610 Of course, there is a more practical solution. 05:54.550 --> 06:00.250 You can always switch the user to root so we don't have to write pseudo for every command that requires 06:00.250 --> 06:01.030 room privileges. 06:02.130 --> 06:04.500 So let's run pseudo asou. 06:05.860 --> 06:11.830 OK, so I'm I'm right now, and I'll double check that with the Who am I command? 06:13.710 --> 06:19.350 Well, now I can run any command which requires super user privileges without pseudo. 06:21.380 --> 06:29.660 And this is my IP address, if if Config didn't obtain an IP address, that means that you have a problem 06:29.660 --> 06:33.600 with your network configuration, it's not a problem. 06:33.950 --> 06:35.150 Problems do occur. 06:35.360 --> 06:42.050 And I certainly will give you some solutions to fix any possible network problems in the next lecture.
