WEBVTT 00:00.080 --> 00:03.020 Great you have successfully installed the Raspberry Pi OS. 00:03.050 --> 00:09.050 You have configured the Wi-Fi and you know the IP address of the Raspberry Pi in the network. 00:09.050 --> 00:15.260 What we can do now is to use SSH to take control over the Pi and really get access to it. 00:15.260 --> 00:21.770 This will provide you with command line access in a terminal, which we will use just in the next lesson 00:21.770 --> 00:25.700 to install VNC and get access to the Raspberry Pi desktop. 00:25.700 --> 00:30.440 And don't worry too much about understanding command lines and how a terminal works here. 00:30.440 --> 00:34.070 We will come back to it in a future section of this course. 00:34.070 --> 00:39.350 For now, this is just a required step of the configuration, so please follow every instruction one 00:39.350 --> 00:40.070 by one. 00:40.070 --> 00:46.010 And the first thing we are going to do just to make sure that we don't have an error later on you can 00:46.010 --> 00:48.170 open a file manager. 00:48.680 --> 00:53.750 So let's open a file manager on your computer and just browse to this PC. 00:54.110 --> 01:00.470 And then you basically want to go in there and go to users and just find your user okay. 01:00.500 --> 01:06.260 So just go to basically what we can call the home directory in Linux or in Mac OS. 01:06.290 --> 01:09.850 It's going to be where you place the folder where you have your user. 01:09.970 --> 01:15.670 And in this you will find a folder named dot ssh. 01:15.700 --> 01:19.840 If you don't see this one, maybe it's probably because it's hidden somewhere. 01:19.840 --> 01:25.960 So you can click on view and show show hidden items. 01:25.990 --> 01:27.010 Okay something like that. 01:27.010 --> 01:35.980 So if you find dot ssh folder in the directory for your main user, you go in there and you have a file 01:36.010 --> 01:38.170 named Knownhosts. 01:38.260 --> 01:39.670 I also have that one too. 01:39.670 --> 01:41.290 And I'm just going to remove those. 01:41.320 --> 01:41.560 Okay. 01:41.590 --> 01:45.130 So you just remove those files and that's it. 01:45.340 --> 01:49.930 If you really can't find this folder I guess it's okay if you don't have an error later on. 01:49.930 --> 01:50.770 That's fine. 01:50.770 --> 01:53.140 This is kind of a preventive step. 01:53.200 --> 01:53.410 Okay. 01:53.440 --> 01:57.850 So now we can close this and we will need to open a terminal. 01:57.850 --> 02:00.010 So how to open a terminal on windows. 02:00.010 --> 02:06.670 Just go to the search bar or press the windows key and type something like cmd okay command prompt. 02:06.670 --> 02:12.370 You can open that okay I guess on macOS is going to be similar. 02:12.410 --> 02:16.760 and well, if you are using Linux, you probably know how to open a terminal already. 02:16.760 --> 02:22.040 So just open a terminal and the command is going to be the same for windows, macOS and Linux. 02:22.070 --> 02:25.340 Okay, we are going to use the SSH command. 02:25.340 --> 02:30.620 So if you press SSH and enter you should have this kind of message okay. 02:30.650 --> 02:32.570 Usage ssh. 02:32.570 --> 02:34.970 That means that the SSH command exists. 02:35.000 --> 02:39.020 In some older versions of windows you might not have SSH. 02:39.020 --> 02:41.300 In this case you can use some putting on the screen. 02:41.300 --> 02:44.420 Here you can use a software called putty okay. 02:44.450 --> 02:50.660 You can download it install it and just provide the IP address, the username and the password to connect 02:50.660 --> 02:51.770 to SSH. 02:51.770 --> 02:59.150 But I guess that for most of you watching this video, you should be able to have the SSH command installed 02:59.150 --> 03:00.140 on your computer. 03:00.140 --> 03:01.460 So now what do we need to do? 03:01.460 --> 03:05.210 Well we will write SSH and space. 03:05.210 --> 03:10.220 And then you need to put which user will you want to connect as on the Raspberry Pi. 03:10.220 --> 03:14.990 And if you remember we have created a user with the name Pi okay. 03:14.990 --> 03:18.290 So if you have used a different name change it here. 03:18.310 --> 03:23.110 But if you just follow the video exactly as I did, you should have the user pi. 03:23.140 --> 03:27.910 Then you put the At and we will need to put the IP address of the Raspberry Pi. 03:27.910 --> 03:29.350 So what's the IP address? 03:29.350 --> 03:31.780 This is the one we have found right here. 03:31.870 --> 03:41.500 So for me it's 192 dot 168 .203. 222. 03:41.530 --> 03:42.790 So don't just copy this. 03:42.820 --> 03:46.540 Of course your IP address is going to be different. 03:46.900 --> 03:55.720 Now I can press enter and if everything worked well you should see a message like this okay the authenticity 03:55.720 --> 03:57.610 of host etc. etc.. 03:57.640 --> 04:00.490 Basically the question is are you sure you want to continue? 04:00.520 --> 04:01.750 Yes or no? 04:01.750 --> 04:05.530 And you just put yes and you press enter. 04:05.950 --> 04:10.360 And now it should ask you for the password of the pi user. 04:10.390 --> 04:11.080 Okay. 04:11.110 --> 04:17.170 If you didn't get that, if you got an error with this known host thingy, then you need to go back 04:17.170 --> 04:21.100 and remove this known host file like I just showed you in the beginning of the video. 04:21.100 --> 04:23.500 But if you see the password like this, all fine. 04:23.530 --> 04:27.590 You just put the password that you have provided during the setup. 04:27.590 --> 04:32.750 So when you flashed the operating system and here you can see when I type something it doesn't show. 04:32.750 --> 04:36.050 So you just type the password and you press enter. 04:36.050 --> 04:38.480 If you provided the correct password. 04:38.510 --> 04:43.370 Now you can see that we are actually inside the Raspberry Pi okay. 04:43.400 --> 04:45.920 It's not this anymore. 04:45.920 --> 04:48.440 So we are not operating from windows. 04:48.470 --> 04:55.790 Now you can see we have Pi at Raspberry Pi and we have a command line from inside the Raspberry Pi. 04:55.790 --> 05:00.800 And well, if you have an error with the password, it is simply because this is the wrong password. 05:00.830 --> 05:01.370 Okay. 05:01.400 --> 05:05.780 If you manage to get the and the password doesn't work, make sure you don't have a typo. 05:05.810 --> 05:10.940 Also, make sure that maybe your keyboard is configured the same and you type exactly the same thing 05:10.940 --> 05:13.760 that you typed when you set up the Raspberry Pi. 05:13.760 --> 05:18.560 And maybe you made a mistake, and maybe you need to flash the operating system again if you provided 05:18.590 --> 05:19.940 a wrong password. 05:19.970 --> 05:20.330 Okay. 05:20.360 --> 05:23.120 And now great, we are on the Raspberry Pi. 05:23.150 --> 05:25.700 So we have internal access to the Raspberry Pi. 05:25.730 --> 05:31.070 The next thing we can do is to set up VNC so we can have access to the desktop.
