Hello and welcome to this Callie Fundamentals video. I'm very excited to work with you today.
00:05
So if you're wondering, how do I get started with using Callie? I want to get it downloaded, get it working, but I want to do it securely. Great questions. So those are some of the objectives that we're going to be touching on here soon? How to safely now mode, Callie, and validate that. It is in fact, secure some basic,
00:23
you know, use of a hyper visor and how to find one and what that is.
00:26
And knowing that a high level of the differences between, ah, full installation versus a life boot of Callie. So let's go ahead and jump into where we can get Callie from.
00:36
So using your Web browser, you can navigate to Callie, not ord slash downloads. Now there's a lot of different distributions, but we're going to focus on the 64 bit or 32 bit variants of that. We did a quick click over here to download the flavor of choice, and you'll notice that's happening, that there's a check some over here to the right,
00:54
so keep that in mind will touch on that here in a moment,
00:57
and I'll show you how that check some could be valuable in ensuring that your tools are secure. So let's go ahead and top at a high level about hyper visor and what that is, and you know how that's gonna help us to run Kallie. So I did a quick search for one of my favorite hyper visors, being where workstation player. So
01:17
you can click on the downloads link over here,
01:19
and this will bring you to a page that looks similar to this. At the time being, where 15 workstation player was the current version, I went ahead and downloaded that for Windows. Now
01:30
you can use a different hyper visor to run this system. Essentially, what this is doing is you have at the base your current operating system, and this hyper visor is going to allow you to run what's called a guest or a guest operating system. On top of that, so this will be Callie or
01:48
any other thing you want to run. It's kind of like conception into dream within a dream.
01:53
This is just a operating system within an operating system. You don't have to do a boot or do anything of that nature. You can just run it with your current hardware, and resource is it makes it a little bit more convenient. So remember we talked about that, check some in what we were gonna do with it. Let's touch on that at a high level as well.
02:09
So they check some is a way that we can validate the integrity of a file. So in this case, we look at this shot to 56. Check some Mike here, and those were with her over here to the right. So if you take this file, do a check some using shot 2 56 those numbers should mash.
02:27
So I used a tool that's online. It's called online MD five dot com was the site
02:31
and you get a window that looks like this on the main page. I simply selected my downloaded version of Callie and selected the shot to 56. Check some type, so it ran, and it provided me with this output. So what I did is I took the output and I compared it with the number that I had here. And lo and behold, we had a match.
02:52
So what that tells me is that my tool
02:53
should not have been altered, and it should be in a safe state. You always want to check your tools in. That just ensures that you don't give him the infections or bad guys on your systems.
03:02
So speaking of check sons and checking those, let's do a quick check on learning
03:07
a tool that allows you to run a virtual machine is known as so. We use this word a couple times. Hardware? Definitely not. So hardware allows you to run tools without hardware. You really can't. But in this case, we're talking about the specific tool, not hardware. We didn't mention hyper terminals
03:24
or using a hyper terminal that's typically used for configuring devices and things of that nature.
03:30
Not in this case, isn't allowing us to run virtual machines, so the likely choice here is a hyper visor, Remember? Ah, hyper visor allows us to run an operating system within an operating system, so let's go ahead and prepare for takeoff. You should go ahead and install your hyper visor of choice. In this case, you're going to be looking at
03:50
VM Wear Player and how we set Callie up from here.
03:53
So once you get Veum, where player installed or your hyper visor of choice. In my instance, I've already got several machines here, but you're going to go ahead and create a new virtual machine using the ice so that you've downloaded. So once you create a new virtual machine, it's going to give you this option
04:11
and ask you to point to the file.
04:13
So what you'll do is I downloaded my copy of county to a thumb drive, selected it and bam, There we go. It gives me this out of this new option here. Now, you may know that the ram is a little bit lower on your machine. If you want to make an adjustment and change a few things with how
04:30
resource is there going to be allocated to this virtual machine,
04:33
then you can edit those settings here. When you click edit settings. You've got a couple options under hardware, at least in the V M, where player
04:43
hyper visor. And from there
04:46
I went ahead and selective memory
04:48
bumped up the volume a little bit on that. And now I've got two gigs to you. So when you're ready to get started. You can go ahead and click the play button here in this case, and you should get something that looks like this. Now.
05:01
In this instance, we're going to be using live boot and talking about that at a high level. Lifeboat essentially allows me to not have to install Callie, and it essentially just starts running. Allows me to jump right in and start working with some commands and some tools and doing some things. But it's not persistent meaning. If I
05:19
reboot the system, lose the system, have to power down. For some reason,
05:25
I lose all my work and information. But for the sake of the lessons will be doing, lifeboat is going to be the quickest and easiest way to get started. If you want to do a full install, which is going to have persistence, it will maintain information between reboots. It'll allow you to do Cem customization things of that nature. By all means. Go ahead and do a graphic installing work with it from there.
05:45
But once you live boot into the Cali environment,
05:47
you'll be ready to go and should just have a desktop in, and you can run and gun from there and the continued lessons and follow along with us there.
05:55
So with those things in mind, let's do a quick check of learning, and we just talked about this. So keep that in mind. What is the primary difference between, like boot and a full installation based on the options here? Well, we didn't talk about this, but live brute is definitely not faster with the boot time. So you know that is not a benefit of life boot.
06:15
There's not a greater amount of tools or less amount of tools available based on one or the other.
06:18
You can add tools to the installation if you do a full install. But if you do that in my boot and then reboot, you lose that. And that comes to our answer here that there's no persistence between reboots with lab boots. So that's a very, very major difference between a full installation in life boot. Now I wanna point out some additional resource is that you can use
06:39
for those of you that have access to the lambs and things of that nature.
06:43
I used the host data integrity based lining lamp, and they have a copy of Cali Lennox under the machines that you can use if you're not looking too down, little high provides her and do an installation on your system, and you would just rather jump right in and be able to work with some commands and start navigating the environment.
07:01
This is a good lab and virtual machine used to keep in mind.
07:05
As we discussed previously. You may see some differences in some areas of this version versus the version you may see me using in our navigation videos and things of that nature. The command should still be the same, and again, the team is always updating tools, updating what they use. So you may see some differences, but don't fret.
07:24
The underlying commands that will use they're gonna remain the same
07:28
now. In summary, we went over Callie and a hyper visor and gave you some tips and tricks on how to ensure that those things were secure and safe when you're using them. We did some high level differences between life boot in a full installation, and I gave you a few additional resource is that you could use
07:44
instead of having to install everything and just jump right in and start working some commands.
07:48
So I thank you for your time today, and I look forward to working with you again soon.
