Cali fundamentals lesson. 1 00:00:03.800 --> 00:00:06.900 I'm very excited to be here with you today. So 2 00:00:06.900 --> 00:00:09.400 what we're getting ready to jump into and what 3 00:00:09.400 --> 00:00:12.500 we're getting ready to discuss is how did you manage users in 4 00:00:12.500 --> 00:00:15.100 Cali? And so you may be asking yourself? You know, I know 5 00:00:15.100 --> 00:00:18.200 that I come in as root. I know that that's the default user. What 6 00:00:18.200 --> 00:00:21.100 if I want to add a user for day-to-day use or what if I 7 00:00:21.100 --> 00:00:24.400 want to add a user for testing purposes. Well, 8 00:00:24.400 --> 00:00:27.500 now's the time to discuss that so our lessons 9 00:00:27.500 --> 00:00:30.300 lesson objectives today is to walk away 10 00:00:30.300 --> 00:00:33.200 with a high level ability to check current users and groups. 11 00:00:33.200 --> 00:00:36.100 And so again, you know, we just want to know what's on the 12 00:00:36.100 --> 00:00:39.600 system and then the ability to add and delete users. So 13 00:00:39.600 --> 00:00:42.300 this isn't a long lesson and we've just got some high points 14 00:00:42.300 --> 00:00:44.500 to touch on. So, let's Jump Right In 15 00:00:45.300 --> 00:00:48.400 So when we're wanting to check users and groups and and as 16 00:00:48.400 --> 00:00:51.100 they are in the Cali distribution, you're essentially going to 17 00:00:51.100 --> 00:00:54.200 be going to this Etsy password file. So you'll 18 00:00:54.200 --> 00:00:57.900 go to the Etsy directory and there's a file there called past WD 19 00:00:57.900 --> 00:01:00.900 and what you can do is you can run concatenate against 20 00:01:00.900 --> 00:01:03.800 that or the group file and 21 00:01:03.800 --> 00:01:06.600 it'll give you these outputs here. So you'll notice on this 22 00:01:06.600 --> 00:01:09.600 end. We went to the Etsy directory using 23 00:01:09.600 --> 00:01:12.300 that CD command. And then from there what you'll 24 00:01:12.300 --> 00:01:15.400 do is you'll notice that we ran cap password. Now, if 25 00:01:15.400 --> 00:01:18.800 you look over to the left of this line You'll see 26 00:01:18.800 --> 00:01:21.100 that we've got sis and Ben and Damon and 27 00:01:21.100 --> 00:01:24.300 root. These are all users on the system 28 00:01:24.300 --> 00:01:27.200 and some of these are running, you know in some of 29 00:01:27.200 --> 00:01:30.700 these areas with no login permissions as it states over here and 30 00:01:30.700 --> 00:01:33.300 so we can't log into those users. So they're they're really 31 00:01:33.300 --> 00:01:36.600 for service purpose or some other purpose. And then when 32 00:01:36.600 --> 00:01:39.200 we did the same thing with the group file, you'll notice here. 33 00:01:39.200 --> 00:01:42.200 We ran Kat against group in that same Etsy 34 00:01:42.200 --> 00:01:45.200 folder. It shows us again the current 35 00:01:45.300 --> 00:01:49.000 Groups that are in our distribution so not 36 00:01:48.300 --> 00:01:51.000 a lot there. It's really just, you know 37 00:01:51.300 --> 00:01:54.300 going to that particular file and being able to see what's on the 38 00:01:54.300 --> 00:01:55.600 system. So as you continue 39 00:01:56.200 --> 00:01:59.300 to Linux or if you use it day to day and you feel 40 00:01:59.300 --> 00:02:02.400 maybe there's a user on the system that you need to check into 41 00:02:02.400 --> 00:02:05.800 or that you may not have been aware of or if you just check regularly, you 42 00:02:05.800 --> 00:02:09.100 can use these two locations to give you a better idea of 43 00:02:08.100 --> 00:02:11.300 you know, what's going on in your distribution or 44 00:02:11.300 --> 00:02:14.600 to ensure that you've you know added a 45 00:02:14.600 --> 00:02:17.100 user correctly. So let's go ahead and talk about that for a 46 00:02:17.100 --> 00:02:20.800 moment as well. So when we look at adding and deleting users, which 47 00:02:20.800 --> 00:02:23.200 you've got here is the ad user command and the 48 00:02:23.200 --> 00:02:26.800 user delete command or Dell command and that here this 49 00:02:26.800 --> 00:02:29.400 is just where you replace username with 50 00:02:29.400 --> 00:02:32.200 the actual username. So as you can see here, we were still in that 51 00:02:32.500 --> 00:02:35.600 Etsy folder and we were able to execute the ad user 52 00:02:35.600 --> 00:02:38.400 command and we added a test user and it went 53 00:02:38.400 --> 00:02:41.400 through each of these areas, you know describing what 54 00:02:41.400 --> 00:02:44.800 was adding the user adding the group it created a home directories 55 00:02:44.800 --> 00:02:47.200 you can see here and then it asks us 56 00:02:47.200 --> 00:02:50.600 for a password which we just did test in this case and then 57 00:02:50.600 --> 00:02:53.300 it asks for all this information to describe the user 58 00:02:53.300 --> 00:02:56.000 and then at the end it designates whether or not it's 59 00:02:56.100 --> 00:02:59.500 Correct. And so once you go through that process and we went back 60 00:02:59.500 --> 00:03:02.800 to that past WD file and 61 00:03:02.800 --> 00:03:05.200 we did a CAT again. We'll see here at the end that we now 62 00:03:05.200 --> 00:03:08.500 have a test user. So when we then on the 63 00:03:08.500 --> 00:03:11.500 other side of that run the user Dell command and we 64 00:03:11.500 --> 00:03:15.100 put test on the end as you can see here. It 65 00:03:14.100 --> 00:03:17.400 runs. It doesn't give you any feedback. If 66 00:03:17.400 --> 00:03:20.500 the entry was correct, but then we'll see once we look in that 67 00:03:20.500 --> 00:03:23.200 past WD file again 68 00:03:23.200 --> 00:03:25.700 that the test user is no longer there. 69 00:03:26.700 --> 00:03:29.200 So with those things in mind, let's just 70 00:03:29.200 --> 00:03:32.400 do a real brief check on learning. So what is 71 00:03:32.400 --> 00:03:35.900 the name of the file containing current users? And 72 00:03:35.900 --> 00:03:38.400 so we talked about two types 73 00:03:38.400 --> 00:03:41.500 of files that had some information in them which one 74 00:03:41.500 --> 00:03:42.500 had current users. 75 00:03:45.300 --> 00:03:48.300 All right, so looking at the options that we have here 76 00:03:48.300 --> 00:03:51.500 SSH config is a config file. 77 00:03:51.500 --> 00:03:54.500 So there's definitely not user information in 78 00:03:54.500 --> 00:03:57.800 that. We didn't talk about a user's file 79 00:03:57.800 --> 00:04:00.300 or anything of that nature. We did talk 80 00:04:00.300 --> 00:04:04.500 about group. But again in this particular file, it 81 00:04:03.500 --> 00:04:06.300 has group information and the 82 00:04:06.300 --> 00:04:09.600 past WD file contained a 83 00:04:09.600 --> 00:04:12.700 lot of information to include current users. 84 00:04:12.700 --> 00:04:15.400 So if you guessed past WD you did 85 00:04:15.400 --> 00:04:18.200 an excellent job there. So again, this was 86 00:04:18.200 --> 00:04:22.100 a brief lesson. We didn't want to get too deep into, you know 87 00:04:22.100 --> 00:04:25.100 users and adding into leading users. Just really a high 88 00:04:25.100 --> 00:04:28.400 level way that you can start to manipulate users is if 89 00:04:28.400 --> 00:04:31.500 you need them for testing purpose, or if you're going to create an 90 00:04:31.500 --> 00:04:34.400 account for day-to-day purposes, and so we learn 91 00:04:34.400 --> 00:04:37.600 how to check those users in groups using that past WD and 92 00:04:37.600 --> 00:04:40.400 group files in the Etsy directory, and then 93 00:04:40.400 --> 00:04:43.500 we talked about how to add and delete users. So 94 00:04:43.500 --> 00:04:44.600 I want to thank you for 95 00:04:44.900 --> 00:04:47.400 Wanting me today, and I look forward to seeing you 96 00:04:47.400 --> 00:04:48.200 again soon.
