1 00:00:00,180 --> 00:00:02,490 ‫So the second step is to install COMMI. 2 00:00:02,940 --> 00:00:08,040 ‫Well, since will use the ovei file, it would be better to say import for this step. 3 00:00:09,040 --> 00:00:12,580 ‫And the downloads finished it under the download folder. 4 00:00:13,270 --> 00:00:15,580 ‫Now I'll open a virtual box interface. 5 00:00:16,060 --> 00:00:17,080 ‫Choose Import. 6 00:00:18,240 --> 00:00:23,490 ‫And choose the over file under the download folder and click Continue. 7 00:00:25,440 --> 00:00:31,170 ‫So as you can see, there are the suggested settings of virtual box for the imported virtual machine. 8 00:00:32,590 --> 00:00:34,510 ‫RAM is two gigs by default. 9 00:00:36,360 --> 00:00:41,250 ‫Now, just click import and agree to the license agreement in order to continue. 10 00:00:45,510 --> 00:00:48,600 ‫And it starts to import and may take a couple of minutes. 11 00:00:49,530 --> 00:00:53,550 ‫So I want to look at the size of the empty space on my host. 12 00:00:56,950 --> 00:01:05,350 ‫Def Command simply displays the free disk space and Dash eight parameter makes the result human readable. 13 00:01:06,400 --> 00:01:12,580 ‫Now I have 140 gigabytes of free space, and that should be plenty for this insulation. 14 00:01:23,480 --> 00:01:30,470 ‫Installations finished, and this is a summary of the the RAM is two gigabytes by default. 15 00:01:31,550 --> 00:01:35,420 ‫And if you have enough RAM on your whole system, I suggest you increase it. 16 00:01:36,650 --> 00:01:39,050 ‫Networking is not just as I want. 17 00:01:40,860 --> 00:01:42,510 ‫Now, just click on the Start button. 18 00:01:44,370 --> 00:01:44,730 ‫OK. 19 00:01:44,760 --> 00:01:50,880 ‫The virtual machine could not be started, so I wonder about the details of this error. 20 00:01:50,910 --> 00:01:51,360 ‫Don't you? 21 00:01:52,900 --> 00:02:00,460 ‫OK, then, so to fix this problem, we'll need to install the Oracle VM VirtualBox extension pack. 22 00:02:01,580 --> 00:02:05,360 ‫So I copy this part and I'll just search on the Web. 23 00:02:07,030 --> 00:02:10,390 ‫So now let's look at the official site of VirtualBox. 24 00:02:12,040 --> 00:02:16,840 ‫We can download it under the title of Oracle VM VirtualBox extension pack. 25 00:02:18,340 --> 00:02:20,770 ‫Total, just click on this link and save the file. 26 00:02:22,470 --> 00:02:23,940 ‫And it quickly downloads. 27 00:02:25,960 --> 00:02:28,120 ‫So let's open the file and click install. 28 00:02:30,340 --> 00:02:35,770 ‫And again, I'll accept the virtual license agreement and finally enter the password to complete the 29 00:02:35,770 --> 00:02:36,490 ‫installation. 30 00:02:40,700 --> 00:02:42,740 ‫And now it's been installed successfully. 31 00:02:44,460 --> 00:02:49,620 ‫So now I'd like to go to the preferences and double check the extension packages. 32 00:02:53,620 --> 00:02:57,850 ‫And everything is OK, good, so now we can start again. 33 00:03:02,810 --> 00:03:05,830 ‫OK, so our Kelly is booting for the first time. 34 00:03:07,070 --> 00:03:10,160 ‫Quick switch for the full screen mode. 35 00:03:18,870 --> 00:03:20,910 ‫And here we are at the login screen. 36 00:03:21,920 --> 00:03:27,320 ‫Now, in addition to the changes that I mentioned in the previous lecture, there is another important 37 00:03:27,320 --> 00:03:36,320 ‫change in this county 2020. to release the default user account is now a standard unprivileged user. 38 00:03:37,190 --> 00:03:42,620 ‫Callie is no longer using this super user account route by default, right? 39 00:03:42,950 --> 00:03:47,630 ‫So the new default credentials are calling and calling. 40 00:03:51,890 --> 00:03:55,010 ‫And welcome to Carly 2020. to. 41 00:03:56,510 --> 00:04:02,270 ‫Now, normally, the screen resolution automatically fits your particular screen, but if you have any 42 00:04:02,270 --> 00:04:08,690 ‫resolution problems like I appear to be having, you can change the scale for your screen. 43 00:04:09,590 --> 00:04:12,800 ‫So first, I'll just open up the display settings. 44 00:04:14,980 --> 00:04:21,760 ‫And I can choose the resolution value to be 1920 by 1200 and click the apply button. 45 00:04:25,690 --> 00:04:26,770 ‫Now go to preferences. 46 00:04:27,710 --> 00:04:31,460 ‫And under the Display tab, you can change the scale factor. 47 00:04:32,470 --> 00:04:35,950 ‫So I'll set this value to be 190 percent of my screen. 48 00:04:36,980 --> 00:04:41,300 ‫And you can change it whatever you want and just try different values for your screen. 49 00:04:42,500 --> 00:04:43,970 ‫All right, so I'll click OK. 50 00:04:44,390 --> 00:04:45,770 ‫Now let's look at the changes. 51 00:04:53,630 --> 00:04:54,710 ‫Yeah, that's pretty good. 52 00:04:59,620 --> 00:05:03,130 ‫So let's open a terminal screen and check the network connection. 53 00:05:05,670 --> 00:05:12,240 ‫When I run the if config command with standard user privileges, I will get an error because they have 54 00:05:12,240 --> 00:05:16,920 ‫config command is under the Espin folder and requires root privileges. 55 00:05:18,030 --> 00:05:20,790 ‫So why don't we have a look inside that has been folder? 56 00:05:22,700 --> 00:05:30,050 ‫As you can see, I can run this CD, P, W, D and the last commands without pseudo, these commands 57 00:05:30,050 --> 00:05:31,940 ‫do not require root privileges. 58 00:05:32,690 --> 00:05:36,590 ‫However, their commands that are under the s been folder must be run with pseudo. 59 00:05:37,510 --> 00:05:38,530 ‫If config is here. 60 00:05:39,700 --> 00:05:41,560 ‫And let's run this command with pseudo. 61 00:05:47,690 --> 00:05:48,710 ‫And it's OK now. 62 00:05:50,690 --> 00:05:53,580 ‫Of course, there is a more practical solution. 63 00:05:54,550 --> 00:06:00,220 ‫You can always switch the user to root, so we don't have to write pseudo for every command that requires 64 00:06:00,220 --> 00:06:01,000 ‫root privileges. 65 00:06:02,160 --> 00:06:04,500 ‫So let's run sudo su. 66 00:06:05,920 --> 00:06:11,800 ‫OK, so I'm I'm right now, and I'll double check that with the WHO am I command? 67 00:06:13,710 --> 00:06:19,320 ‫Well, now I can run any command which requires superuser privileges without pseudo. 68 00:06:21,410 --> 00:06:29,630 ‫And this is my IP address, if if config didn't obtain an IP address, that means that you have a problem 69 00:06:29,630 --> 00:06:33,590 ‫with your network configuration, it's not a problem. 70 00:06:33,950 --> 00:06:40,760 ‫Problems do occur and I certainly will give you some solutions to fix any possible network problems 71 00:06:41,060 --> 00:06:42,020 ‫in the next lecture.
