1 00:00:05,320 --> 00:00:10,090 Welcome back, everyone, to this lecture on the state's connection or secure shell connection. 2 00:00:10,240 --> 00:00:15,760 Now we're going to perform in order to connect our computers local terminal to the terminal at your 3 00:00:15,760 --> 00:00:16,690 actual linoleum. 4 00:00:17,680 --> 00:00:23,650 So S.H. or secure shell allows us to securely connect to the Lennart server that's hosting our jingo 5 00:00:23,650 --> 00:00:24,220 project. 6 00:00:24,610 --> 00:00:29,290 And we don't just want anybody to be able to visit this computer and start editing our jingo project 7 00:00:29,290 --> 00:00:30,340 files without permission. 8 00:00:30,760 --> 00:00:36,730 So what we do is we use an S-H or secure cell connection, which is going to require the password you 9 00:00:36,730 --> 00:00:39,920 set up during the Lynott setup process and the previous lecture. 10 00:00:39,940 --> 00:00:43,960 That's why it's so important to remember that password in order to actually connect to the actual out 11 00:00:43,960 --> 00:00:44,530 later on. 12 00:00:45,910 --> 00:00:51,280 Now, keep in mind, S.H. can actually be really intimidating for first time users, but in reality, 13 00:00:51,280 --> 00:00:52,110 it's pretty simple. 14 00:00:52,120 --> 00:00:56,620 It's just a way of connecting your computer to another computer through the internet securely. 15 00:00:56,980 --> 00:01:01,720 All we need to actually do is just say, Hey, I want to connect to this computer at this IP address 16 00:01:01,930 --> 00:01:05,530 and then in order to confirm permission, you pass in the password. 17 00:01:05,620 --> 00:01:12,760 Thus, the secure shell and what we end up resulting in is having an actual shell or terminal access 18 00:01:12,760 --> 00:01:16,570 to the computer that is right now for us living in Dallas, Texas. 19 00:01:17,980 --> 00:01:22,840 Now, once we connect through SS H, we're going to again have access to the Debian Linux shell that's 20 00:01:22,840 --> 00:01:28,150 located at the Linux server, which allows us to then use Linux commands at the terminal for installations 21 00:01:28,150 --> 00:01:32,590 and setups, much like we have access to our local command line. 22 00:01:34,130 --> 00:01:39,680 Now, a couple of important notes, Lenovo itself actually provides really great documentation on connecting 23 00:01:39,680 --> 00:01:41,710 on Leno through speech. 24 00:01:42,050 --> 00:01:46,820 So in case you're actually interested in that, you can just go to Lynda.com for stock sports guides. 25 00:01:47,090 --> 00:01:52,820 And there's multiple guides, whether you're on putty, Linux, Windows, Mac OS, it's actually just 26 00:01:52,820 --> 00:01:56,840 go to guides, connect a server over, switch on and then Mac Windows. 27 00:01:56,840 --> 00:02:00,710 And there's actually a little dropdown that allows you to select for different operating systems in 28 00:02:00,710 --> 00:02:03,260 case you want a more step by step written guide. 29 00:02:04,310 --> 00:02:10,310 OK, so if you're a Mac OS or Linux user, you have a little more luck in this because this is already 30 00:02:10,310 --> 00:02:14,750 coming with the ability to connect through speech and essentially all you need to do is copy and paste 31 00:02:14,750 --> 00:02:19,880 the message command from the little panel at the terminal, which if you remember, it was right next 32 00:02:19,880 --> 00:02:21,700 to the IP address information. 33 00:02:21,710 --> 00:02:23,120 And there's essentially two parts of this. 34 00:02:23,450 --> 00:02:28,430 There's speech, which is the actual command line prompt, saying, Hey, I want to securely connect 35 00:02:28,430 --> 00:02:29,270 to a shell. 36 00:02:29,540 --> 00:02:33,520 And then you say, I want to do it at the root node at this IP address. 37 00:02:33,530 --> 00:02:36,200 Obviously, your IP address is going to be different than mine. 38 00:02:36,410 --> 00:02:40,270 And then once you do that, it may ask you a question of Are you sure you want to connect? 39 00:02:40,280 --> 00:02:41,690 I can't verify the fingerprint. 40 00:02:41,930 --> 00:02:45,860 That's essentially your computer telling you, Hey, are you sure this isn't some hackers telling you 41 00:02:45,860 --> 00:02:46,960 to visit this IP address? 42 00:02:46,970 --> 00:02:50,000 You're going to say Yes, it's OK, and then I'll ask you for the password. 43 00:02:51,330 --> 00:02:56,460 Now, if you're on windows, it's going to be a little extra steps because windows by default don't 44 00:02:56,460 --> 00:02:58,470 actually have S.H. typically. 45 00:02:58,830 --> 00:03:04,050 So you can use the PowerShell to connect, but you actually have to first install the Open H client, 46 00:03:04,350 --> 00:03:07,050 which is done through manage optional features on windows. 47 00:03:07,980 --> 00:03:11,880 So what we're going to do because I'm going to Windows Machine and actually most people are usually 48 00:03:11,880 --> 00:03:12,720 on Windows machines. 49 00:03:13,050 --> 00:03:18,840 Even though Mac OS is quite popular with programmers, the vast majority of users are actually still 50 00:03:18,840 --> 00:03:19,380 on Windows. 51 00:03:19,410 --> 00:03:24,060 So what we're going to do is I'm going to show you how to quickly install the open SSA client on a Windows 52 00:03:24,060 --> 00:03:24,480 machine. 53 00:03:24,720 --> 00:03:30,060 That way, we can get some access and then all users can then follow along at the Debian terminal with 54 00:03:30,060 --> 00:03:30,840 the same commands. 55 00:03:30,960 --> 00:03:33,750 So if you're a Mac OS or Linux, you can check out that link. 56 00:03:33,750 --> 00:03:38,640 I posted it in the documentation, which pretty much just says copy and paste that SSA command from 57 00:03:38,640 --> 00:03:40,350 the Lennart panel and you're good to go. 58 00:03:40,650 --> 00:03:43,260 If you're on windows, I'll walk you through those extra steps now. 59 00:03:43,590 --> 00:03:43,830 OK? 60 00:03:44,190 --> 00:03:45,330 Let me head to my computer. 61 00:03:45,720 --> 00:03:48,210 All right, so here I am inside a visual studio code. 62 00:03:48,240 --> 00:03:53,550 Remember, we can hit Terminal to create a new terminal, and the default terminal should be PowerShell. 63 00:03:53,760 --> 00:03:58,800 Remember, you can always hear on this little dropdown arrow and open up a new PowerShell instance. 64 00:03:59,370 --> 00:04:04,620 Now, if you are on a Mac OS or Linux computer, you should have been able to just open up your terminal. 65 00:04:04,620 --> 00:04:07,350 It would have just been a normal terminal, not a Windows PowerShell. 66 00:04:07,620 --> 00:04:13,500 And then all you need to do is come again to your Leonard page here and then just copy and paste the 67 00:04:13,620 --> 00:04:14,750 same access. 68 00:04:14,760 --> 00:04:17,820 So you just need to copy this command, so make sure it's copied. 69 00:04:18,209 --> 00:04:18,810 Come here. 70 00:04:18,839 --> 00:04:22,530 Then you should be able to just right click and or copy paste and you have it here. 71 00:04:22,560 --> 00:04:31,410 Basically, what the saying is S.H. or securely connect using Shell to this root node at this IP address, 72 00:04:31,870 --> 00:04:32,850 then you can hit Enter. 73 00:04:33,800 --> 00:04:38,000 And if you're a Mac OS or Linux that should have worked for you right now, you can see on my Windows 74 00:04:38,000 --> 00:04:42,620 computer it says it doesn't actually recognize the term as some sort of command or function. 75 00:04:43,840 --> 00:04:49,300 So we need to do is make sure that we're at the correct location inside of PowerShell to actually run 76 00:04:49,300 --> 00:04:55,480 this command S-H, and that we have our open SSA client installed as a quick note, as I mentioned in 77 00:04:55,480 --> 00:04:56,020 the slides. 78 00:04:56,350 --> 00:05:00,160 There's actually directions step by step on how to do this on Lennart itself. 79 00:05:00,160 --> 00:05:03,820 If you go to their guides on how to connect to a remote server over SSA. 80 00:05:04,390 --> 00:05:10,630 You can see here I'm specifically on windows, but there's lots of dropdown options like Mac instructions 81 00:05:10,630 --> 00:05:12,820 or Linux instructions, et cetera. 82 00:05:13,150 --> 00:05:16,780 So we're going to do is follow along with the Windows instructions, and what we have to do is check 83 00:05:17,020 --> 00:05:20,080 our manage optional features on actual windows. 84 00:05:20,380 --> 00:05:27,310 So click your Windows key and then check out Manage Optional Features, click on Manage Optional Features 85 00:05:27,490 --> 00:05:31,250 and then check if you have the open access. 86 00:05:31,270 --> 00:05:33,970 Each client already installed on your computer. 87 00:05:34,420 --> 00:05:36,580 If you do have it installed already, then you're good to go. 88 00:05:36,880 --> 00:05:42,610 If not, click on Add feature here and then add open source each client. 89 00:05:42,790 --> 00:05:45,610 You can see here if openness is each client and for good measure. 90 00:05:45,610 --> 00:05:52,510 We're also going to add an install open SSL server, so install there and let it install into your computer 91 00:05:52,810 --> 00:05:56,170 so you have open associates, clients and open SSL server. 92 00:05:56,500 --> 00:05:59,320 Technically speaking, for what we're showing here, you only need the client. 93 00:05:59,320 --> 00:06:03,130 So if you have a client already to go, that should be enough for our applications. 94 00:06:03,370 --> 00:06:05,020 Let's head back now to PowerShell. 95 00:06:05,860 --> 00:06:06,250 All right. 96 00:06:06,280 --> 00:06:08,560 Now here I am back inside PowerShell. 97 00:06:08,740 --> 00:06:11,350 I'm going to make sure to actually restart a new instance a PowerShell. 98 00:06:11,350 --> 00:06:12,520 So those changes take effect. 99 00:06:12,820 --> 00:06:14,200 I'll go ahead and delete this one. 100 00:06:14,570 --> 00:06:17,860 Hit terminal new terminal and open up a fresh PowerShell. 101 00:06:18,220 --> 00:06:23,440 The other thing I want to do is actually see them into where open SSL, which is so I can see. 102 00:06:24,280 --> 00:06:26,830 And then two dots to go back up a directory. 103 00:06:27,190 --> 00:06:29,920 You're going to want to go all the way back up to C drive. 104 00:06:29,950 --> 00:06:36,700 So CD thought that goes back up a directory, CD data backup, another directory CD that that so changed 105 00:06:36,700 --> 00:06:37,630 directory backup. 106 00:06:37,630 --> 00:06:38,860 And now I'm on C drive. 107 00:06:39,250 --> 00:06:44,650 Next thing I want to do is go to under Windows System32 were open source H.S. 108 00:06:44,740 --> 00:06:50,560 So we're going to CD into Windows CD into system. 109 00:06:51,190 --> 00:06:55,480 Thirty two should be able to use Tab to autocomplete these just in case you are having trouble finding 110 00:06:55,480 --> 00:06:55,690 them. 111 00:06:56,140 --> 00:07:02,380 And then after that, you can CD into open access h and it's actually s h or capital there. 112 00:07:02,890 --> 00:07:03,190 OK. 113 00:07:03,490 --> 00:07:09,280 So I can see how I went back up the directory all the way to C and then went back down into open source 114 00:07:09,280 --> 00:07:09,620 h. 115 00:07:10,090 --> 00:07:14,580 Now, if you copy and paste this command, you may still get an error. 116 00:07:14,590 --> 00:07:18,190 It's going to report something like, Hey, PowerShell is not allowed to run this, so I'm going to 117 00:07:18,190 --> 00:07:19,750 actually show you what that looks like. 118 00:07:20,170 --> 00:07:23,470 So if you hit this, it's going to say the same errors before. 119 00:07:23,680 --> 00:07:29,650 But then I'll also give you this nice suggestion saying that the command SSA wasn't found, but that 120 00:07:29,660 --> 00:07:36,370 specific command does exist in the current location and it's asking us, hey, instead type out this 121 00:07:36,370 --> 00:07:37,990 in order to actually run the command. 122 00:07:38,470 --> 00:07:44,380 So we're going to run the exact same line of code, except now it's going to be dark backslash se h 123 00:07:44,710 --> 00:07:46,900 and then your actual IP address. 124 00:07:46,900 --> 00:07:55,000 So essentially same thing here, except is going to be back or dot backslash as h and then root out 125 00:07:55,480 --> 00:07:59,350 and then that particular IP address or whatever your IP addresses. 126 00:08:00,160 --> 00:08:03,280 So I'm going to say dot backslash SDH. 127 00:08:03,290 --> 00:08:10,660 So again, just to make it clear here the backslash s h and then I'm going to paste in that route. 128 00:08:11,350 --> 00:08:15,780 Enter and now it's going to ask you, Hey, it can't actually authenticate this. 129 00:08:15,790 --> 00:08:16,480 Are you sure? 130 00:08:16,840 --> 00:08:19,630 And then you're going to say yes to continue. 131 00:08:21,300 --> 00:08:23,190 And then it's going to ask you for the password. 132 00:08:23,370 --> 00:08:24,420 So I'm going to pass that in. 133 00:08:27,960 --> 00:08:29,520 Note the password is invisible. 134 00:08:31,430 --> 00:08:32,570 And then here we are. 135 00:08:32,809 --> 00:08:39,919 So now I have successfully connected through SE h onto my Linux server that's in Dallas, Texas, and 136 00:08:39,919 --> 00:08:45,110 essentially right now, what I'm doing is I'm at the command line on that computer that's being hosted 137 00:08:45,110 --> 00:08:48,140 somewhere else in the next lecture will go ahead and set up. 138 00:08:48,140 --> 00:08:48,560 Get. 139 00:08:48,830 --> 00:08:49,400 I'll see you there.
