00:00:00,570 --> 00:00:06,930
Hello and welcome to the official start cop killer Linux Certified Pen Tester Course.

2
00:00:06,930 --> 00:00:10,050
This is the chapter one intro to calling Linux

3
00:00:14,280 --> 00:00:16,890
for going to talk about many different topics here.

4
00:00:16,890 --> 00:00:21,180
This is our table of contents or outline we're going to get into what is Linux.

5
00:00:21,480 --> 00:00:24,780
We'll look at Windows versus the Linux operating system.

6
00:00:25,140 --> 00:00:28,800
We'll look at different components of Linux operating systems.

7
00:00:29,250 --> 00:00:31,560
We'll look at what exactly is a Linux distro.

8
00:00:33,060 --> 00:00:36,180
We'll look at the ethical hacking distribution of Kali Linux.

9
00:00:36,180 --> 00:00:41,280
We'll look at some of the different features and how to choose the right version and download of Kelly

10
00:00:41,280 --> 00:00:41,790
Linux.

11
00:00:42,450 --> 00:00:47,010
We'll also get into the installation of Kelly Linux, whether it's a physical installation on a hard

12
00:00:47,010 --> 00:00:51,570
drive or a virtual installation in VirtualBox software.

13
00:00:54,030 --> 00:00:55,170
So this is the chapter flow.

14
00:00:55,180 --> 00:00:56,370
So what is Linux?

15
00:00:57,330 --> 00:00:58,260
We're in the first part here.

16
00:00:58,260 --> 00:01:04,710
Then we'll get into the differences between Windows and Linux as a whole and why you should choose calling

17
00:01:04,710 --> 00:01:07,920
Linux and then how to download and install it.

18
00:01:13,260 --> 00:01:14,130
So what is Linux?

19
00:01:14,130 --> 00:01:16,380
Just like Windows XP, Windows seven.

20
00:01:16,800 --> 00:01:17,550
Windows eight.

21
00:01:18,210 --> 00:01:19,450
Microsoft Windows ten.

22
00:01:19,450 --> 00:01:21,590
And even Mac OS X.

23
00:01:22,140 --> 00:01:23,550
Linux is an operating system.

24
00:01:24,240 --> 00:01:28,680
It's just all of the software that runs on top of your hardware.

25
00:01:32,050 --> 00:01:38,800
Linux functions much like other operating systems, that it has a toolbar and task bars and can run

26
00:01:38,800 --> 00:01:39,520
programs.

27
00:01:39,850 --> 00:01:41,470
But it's a different underlying architecture.

28
00:01:41,500 --> 00:01:48,790
Linux has been around since the nineties and has since been modified.

29
00:01:50,080 --> 00:01:58,660
Redistributed, retooled and released to where it runs on many, many devices, including your phones,

30
00:01:58,660 --> 00:02:04,270
your car, refrigerators, Roku devices, streaming devices.

31
00:02:04,540 --> 00:02:06,340
It also powers most of the Internet.

32
00:02:06,700 --> 00:02:11,920
Most people don't know that every time you watch Netflix, you're using Linux based servers, most likely

33
00:02:11,920 --> 00:02:12,610
in the cloud.

34
00:02:14,110 --> 00:02:20,950
Linux runs many of the great supercomputers that are making scientific breakthroughs and also the world

35
00:02:20,950 --> 00:02:21,870
stock exchanges.

36
00:02:21,880 --> 00:02:25,240
It's truly an open source operating system.

37
00:02:29,100 --> 00:02:31,830
So how does Windows differ from Linux?

38
00:02:31,830 --> 00:02:34,830
While Linux is a completely open source project?

39
00:02:35,550 --> 00:02:41,330
Linux has various distributions which are highly customizable by the user to suit their needs.

40
00:02:41,340 --> 00:02:45,990
So you can have Linux that runs on really old hardware or really high performing hardware.

41
00:02:47,640 --> 00:02:51,710
Linux is also licensed under the GM new general public license.

42
00:02:51,720 --> 00:02:58,620
So it's free and redistributable as long as it conforms with the terms of the GPL.

43
00:02:59,190 --> 00:03:05,100
Now it is generally considered to be more secure than Windows, as its operating system and components

44
00:03:05,100 --> 00:03:06,990
are not as susceptible to attacks.

45
00:03:07,350 --> 00:03:13,290
It's not that there's not security considerations, but there's just less malware written for Linux.

46
00:03:13,740 --> 00:03:18,540
Linux also supports a wide variety of free software and other benefits to Linux.

47
00:03:18,540 --> 00:03:21,990
Is that the software and the operating system code based?

48
00:03:22,380 --> 00:03:29,530
Because it's open source, it's largely reviewed and vulnerabilities are quickly found and tested amongst

49
00:03:29,550 --> 00:03:36,000
a buzzing community of developers, security practitioners and industry professionals.

50
00:03:37,140 --> 00:03:38,880
Contrasted with Microsoft Windows.

51
00:03:39,210 --> 00:03:41,070
Windows is a closed source software.

52
00:03:41,070 --> 00:03:42,420
It's Microsoft Proprietary.

53
00:03:42,750 --> 00:03:49,020
You either have to purchase a license and they have limited distributions to it went from in the last

54
00:03:49,020 --> 00:03:55,710
iteration of Windows ten, they went down from 5 to 3 different variations of Windows and it cannot

55
00:03:55,710 --> 00:03:57,210
be customized easily.

56
00:03:57,630 --> 00:04:02,040
The windows can do some functionality with respect to Linux.

57
00:04:02,700 --> 00:04:06,570
Windows also requires a license key from Microsoft.

58
00:04:08,170 --> 00:04:16,360
And because Windows is the de facto standard as far as desktop operating systems, it has become a much

59
00:04:16,360 --> 00:04:23,740
bigger target of malware developers because of how easy it is to write malware or to get a reverse shell

60
00:04:23,740 --> 00:04:24,970
from that operating system.

61
00:04:25,930 --> 00:04:28,900
Windows is also very popular amongst gamers.

62
00:04:29,170 --> 00:04:34,960
For example, Valve's Steam platform runs on top of windows, though it does run on Linux.

63
00:04:35,200 --> 00:04:41,560
There are just less games available for it, so it's often a target or more popular choice with respect

64
00:04:41,560 --> 00:04:42,730
to the gaming industry.

65
00:04:48,640 --> 00:04:52,540
So let's talk about some of the components of the Linux OS.

66
00:04:52,780 --> 00:04:54,190
We first have the bootloader.

67
00:04:54,640 --> 00:04:57,490
This is the software that manages the boot process of your computer.

68
00:04:57,940 --> 00:05:00,640
This tells the computer what operating system to boot.

69
00:05:02,320 --> 00:05:03,490
Then we have the kernel.

70
00:05:03,910 --> 00:05:09,320
The kernel is the core of the system, manages the CPU, the memory, and any peripherals that are connected.

71
00:05:09,340 --> 00:05:13,900
The kernel is essentially the lowest level of the operating system.

72
00:05:15,600 --> 00:05:17,820
Then you have the demons or demons.

73
00:05:18,090 --> 00:05:23,940
These are background services, things like printer demons, web servers, scheduling demons, anything

74
00:05:23,940 --> 00:05:30,900
that starts up during boot or once you log in to the desktop and then you have the shell.

75
00:05:31,200 --> 00:05:36,420
This is a command process that allows you to control the computer via the commands typed into the text

76
00:05:36,420 --> 00:05:43,200
interface as a similar to a command prompt on Windows, but it's called the terminal in most Linux distributions.

77
00:05:44,460 --> 00:05:46,740
Then you have the desktop environment.

78
00:05:46,740 --> 00:05:49,920
There are many different desktop environments to interact with.

79
00:05:50,610 --> 00:05:57,530
Some of these are unity, genome, cinnamon, KDE and many others.

80
00:05:57,570 --> 00:06:05,190
So just like Windows and Mac, Linux offers thousands upon thousands of high quality software titles

81
00:06:05,520 --> 00:06:11,730
that can easily be found and installed from various other app stores or repositories.

82
00:06:14,950 --> 00:06:18,340
So Linux has many different versions to suit the different needs.

83
00:06:18,340 --> 00:06:26,530
So whether you're a hardcore user to a new person, you'll find a flavor of Linux that matches your

84
00:06:26,530 --> 00:06:26,950
needs.

85
00:06:27,250 --> 00:06:30,580
These are called distributions or in the short term, distro.

86
00:06:32,170 --> 00:06:36,640
Nearly every version of Linux can be downloaded for free and burned onto a disc.

87
00:06:36,640 --> 00:06:39,400
Some of the prominent Linux letters are listed below.

88
00:06:39,580 --> 00:06:45,570
We have a arslan x db in meant to say.

89
00:06:45,580 --> 00:06:51,760
Of course Red Hat is a commercial version of Linux that does require licensing for the technical support.

90
00:06:52,840 --> 00:06:58,090
There's Santo where someone two and even lightweight distributions of Ubuntu.

91
00:07:08,260 --> 00:07:09,430
So what does Kelly Lennox.

92
00:07:09,430 --> 00:07:13,090
Kelly Lennox was released back on March 2013 as a.

93
00:07:14,540 --> 00:07:19,880
Ground up rebuild of the old backtrack clinics, which is completely division based.

94
00:07:20,360 --> 00:07:21,060
What does that mean?

95
00:07:21,230 --> 00:07:30,830
It DB been based on standards and it's aimed at more advanced penetration testing and security auditing.

96
00:07:31,400 --> 00:07:35,270
So it's been based much like other distros like Ubuntu.

97
00:07:36,020 --> 00:07:37,880
That was a get into the package.

98
00:07:37,880 --> 00:07:42,560
Management will see how that is important for us to understand.

99
00:07:44,660 --> 00:07:49,790
So Kali Linux is also specifically tailored to the needs of penetration testing professionals and therefore

100
00:07:49,790 --> 00:07:55,700
all the documentation assumes that you have some familiarity with the Linux operating system in general.

101
00:07:59,870 --> 00:08:05,000
So some of the key features of Kelley Linux or that it's free software, completely free of charge.

102
00:08:07,910 --> 00:08:10,730
It has an open source git tree, which just means that.

103
00:08:13,490 --> 00:08:20,780
The software updates are delivered via open source and anybody can look at the original source code.

104
00:08:21,950 --> 00:08:24,620
It also has wide ranging wireless device support.

105
00:08:24,620 --> 00:08:31,580
So in the past, LTS distributions have had problems supporting certain types of wireless interfaces

106
00:08:31,580 --> 00:08:33,170
and wireless network cards.

107
00:08:33,920 --> 00:08:37,130
That has largely been a thing of the past recently.

108
00:08:38,000 --> 00:08:43,970
It also has what is known as GPG sign packages in repositories.

109
00:08:44,330 --> 00:08:53,000
This is the new privacy guard, which is a pjp pretty good privacy based encryption system, which means

110
00:08:53,000 --> 00:08:59,450
that all the packages and repositories are signed by the developer and the packages that are inside

111
00:08:59,450 --> 00:09:00,980
of them will be signed as well.

112
00:09:02,030 --> 00:09:07,760
So Kiwi Linux does have multi-language support though many of the tools tend to be written in English.

113
00:09:09,650 --> 00:09:13,850
There are more than 400 pen testing tools listed in the operating system.

114
00:09:17,330 --> 00:09:19,460
You can see here the Kelly Lennox website.

115
00:09:21,260 --> 00:09:26,720
You can look at the latest and greatest news if you want to look at the documentation.

116
00:09:28,310 --> 00:09:30,200
You can see introduction, installation.

117
00:09:30,200 --> 00:09:31,460
There's lots of different options.

118
00:09:32,060 --> 00:09:40,280
If you go to the tools that are inside of Kelly, there are many, many different tools that are out

119
00:09:40,280 --> 00:09:40,580
there.

120
00:09:42,920 --> 00:09:52,070
And Kelly Lennox regularly updates the tools and they sort them by various different functionality.

121
00:09:52,070 --> 00:09:58,400
So if they're a tool built for information gathering or vulnerability analysis, they're sorted into

122
00:09:58,400 --> 00:09:59,420
those categories.

123
00:09:59,750 --> 00:10:03,170
Then you have some tools that are specifically for wireless attacks.

124
00:10:03,920 --> 00:10:10,970
Other tools might be for forensics, password cracking, spoofing, and even reverse engineering.

125
00:10:15,300 --> 00:10:16,680
So what's different about Kelly Olynyk?

126
00:10:16,770 --> 00:10:21,510
Well, it's specifically geared to meet the requirements of professional penetration testing and security

127
00:10:21,510 --> 00:10:21,930
auditing.

128
00:10:23,700 --> 00:10:28,800
So because of the nature of security audits, Kelly Lennox is usually designed to be used in a single

129
00:10:28,800 --> 00:10:30,120
route user scenario.

130
00:10:32,490 --> 00:10:39,210
And many of the network services are disabled by default in order to provide a more secure system by

131
00:10:39,210 --> 00:10:40,710
which to do security audits.

132
00:10:43,170 --> 00:10:49,410
Kelly Lennox has a custom kernel, which is also patched for wireless injection.

133
00:10:49,890 --> 00:10:57,780
And there are many flavors of Kelly, which some are more mental minimalistic and have a trusted set

134
00:10:57,780 --> 00:10:58,890
of repositories.

135
00:10:59,370 --> 00:11:05,250
So the main goal is maintaining the integrity of the software in the system that's installed as a whole

136
00:11:05,490 --> 00:11:12,990
and starting from a known secure baseline is particularly important to security professionals.

137
00:11:15,480 --> 00:11:17,220
So how do we download Kelly Lennox?

138
00:11:17,970 --> 00:11:23,130
Well, the only official source of downloading Kelly ISO images are from the downloads section of Kelly

139
00:11:23,130 --> 00:11:23,760
Borg.

140
00:11:27,490 --> 00:11:28,720
So if you click on the.

141
00:11:32,580 --> 00:11:35,910
If you go back to Kelly's homepage and you go to.

142
00:11:39,100 --> 00:11:40,390
The Download section.

143
00:11:46,370 --> 00:11:53,360
You can see a lot of different options here from native installers to live distributions to over the

144
00:11:53,360 --> 00:11:57,530
network installers and then even the virtualized solutions down here.

145
00:11:58,130 --> 00:12:04,280
There's also some even some weekly builds or some experimental builds that are included in this page

146
00:12:04,280 --> 00:12:04,820
as well.

147
00:12:06,710 --> 00:12:12,200
So depending on your hardware, you can download the flavor of Kelli Lennox to support your needs.

148
00:12:12,560 --> 00:12:19,790
Most of the images will be either 32 or 64 bit suitable for most CPU's, though most computers these

149
00:12:19,790 --> 00:12:27,740
days are becoming 64 bit because of the ability of 64 bit operating systems to handle more than four

150
00:12:27,740 --> 00:12:29,330
gigabytes of memory.

151
00:12:30,350 --> 00:12:38,510
There are some versions of Kali that can be installed on smartphones, Chromebooks or other devices

152
00:12:38,990 --> 00:12:40,430
having an ARM processor.

153
00:12:40,430 --> 00:12:44,750
So you have to use the arm images if you're installing on that particular hardware.

154
00:12:46,920 --> 00:12:51,300
So first of all, we can look at some things to verify integrity.

155
00:12:52,920 --> 00:12:59,490
So when we download our Kelly ISO, we want to make sure that we download a copy that has not been tampered

156
00:12:59,490 --> 00:12:59,820
with.

157
00:13:00,450 --> 00:13:07,050
We can see here that using the SHA256 some utility, we can validate that information now.

158
00:13:07,380 --> 00:13:09,270
This could be done a couple of different ways.

159
00:13:12,320 --> 00:13:18,470
Once you download your ISO, it's important to check and make sure that it's the same matches.

160
00:13:18,470 --> 00:13:19,460
What is on the website.

161
00:13:23,270 --> 00:13:29,060
So my case here, I'm going to scroll back up and I'm going to go get the 64 bit installer and I'm going

162
00:13:29,060 --> 00:13:33,530
to highlight this SHA256 sum.

163
00:13:34,670 --> 00:13:36,280
I'm going to go ahead and download this.

164
00:13:38,000 --> 00:13:43,040
To make sure I have the latest and greatest version and put it on my drive.

165
00:13:45,550 --> 00:13:48,160
I'm going to make a new folder called.

166
00:13:50,890 --> 00:13:51,880
Tally ISO.

167
00:13:54,010 --> 00:13:56,290
I'm going to open that folder and click Save.

168
00:13:58,810 --> 00:14:00,500
And so that'll take a little while to download it.

169
00:14:00,500 --> 00:14:02,930
So it's a little bit less than four gigabytes.

170
00:14:02,930 --> 00:14:09,170
So depending on your Internet connection, you'll have a quick download or a longer download.

171
00:14:09,170 --> 00:14:13,910
You want to make sure that you have if you're putting it on a thumb drive to install that, you have

172
00:14:13,910 --> 00:14:16,630
at least four gigabytes of space on there.

173
00:14:16,640 --> 00:14:22,400
Ideally, eight gigabytes is better because you may need more room for other things.

174
00:14:26,080 --> 00:14:26,320
All right.

175
00:14:26,320 --> 00:14:27,900
Now we've got our ISO downloaded.

176
00:14:27,910 --> 00:14:35,230
I'm going to go ahead and open up a command prompt in Windows, which I already happen to have a version

177
00:14:35,230 --> 00:14:43,930
of Linux installed on here so I can verify my SHA256 sum to make sure my hash is good.

178
00:14:49,630 --> 00:14:50,680
Course it's going to be different.

179
00:14:50,680 --> 00:14:57,940
If you're doing this on Linux, you can just type in the command SHA256 sum and then the file name and

180
00:14:57,940 --> 00:14:58,780
you'll be good to go.

181
00:15:10,840 --> 00:15:12,310
Are we going to see here?

182
00:15:12,310 --> 00:15:18,730
We do the last command and we can see that we have our Kali Linux installer ISO Downloader, so we're

183
00:15:18,730 --> 00:15:24,130
going to do SHA256 some in the name of the file.

184
00:15:26,300 --> 00:15:28,340
And we're going to make sure that it matches.

185
00:15:48,530 --> 00:15:55,280
Are we going to see here that, in fact, that this is our SHA256, some hash right here, starting

186
00:15:55,280 --> 00:15:57,980
with 89 and ending in 87.

187
00:15:58,400 --> 00:15:59,960
So we can see that we do have a match.

188
00:15:59,960 --> 00:16:08,150
So we know we got a correct download so that first we verified the integrity of our image and now we're

189
00:16:08,150 --> 00:16:08,750
good to go.

190
00:16:16,510 --> 00:16:19,540
So how do we make a calculated executable thumb drive?

191
00:16:19,990 --> 00:16:24,610
Well, of course, you need a verified copy of the ISO, which we just obtained.

192
00:16:24,910 --> 00:16:30,820
If you're running on a windows, you need to download some type of Windows imaging utility.

193
00:16:31,120 --> 00:16:36,280
There are many other options there, and you typically need a thumb drive, at least four gigabytes

194
00:16:36,280 --> 00:16:37,000
or larger.

195
00:16:38,170 --> 00:16:42,520
Now we're going to go ahead and make that bootable USB drive.

196
00:16:44,680 --> 00:16:44,890
All right.

197
00:16:44,890 --> 00:16:50,800
Now that I got my USB drive plugged in, I'm going to go ahead and download this 132 disk imager.

198
00:16:51,190 --> 00:16:54,280
You can also use another program I recommend called Unit Boot.

199
00:16:54,280 --> 00:17:00,880
And it's the nice thing about it is you don't have to actually download the software.

200
00:17:01,900 --> 00:17:06,520
ISO first, you can actually have the program, do the work for you.

201
00:17:07,120 --> 00:17:10,510
So it works on multiple operating systems.

202
00:17:10,510 --> 00:17:16,570
But we'll go ahead and download the 132 disk imager and also download you now boot n so you can see

203
00:17:16,570 --> 00:17:24,310
here this works on Windows, Linux and or Mac as well and it will download any type of distribution

204
00:17:24,310 --> 00:17:27,640
that you want or you can supply the ISO yourself.

205
00:17:32,980 --> 00:17:34,030
So we'll go ahead and.

206
00:17:39,780 --> 00:17:44,370
Double check your you want to double check the thumb drive and make sure that you don't have anything

207
00:17:44,370 --> 00:17:51,930
on it that you care about, or at least make a backup of it first because you're going to be overwriting

208
00:17:52,530 --> 00:17:55,980
this drive when you create a bootable thumb drive.

209
00:18:08,230 --> 00:18:08,710
I know that.

210
00:18:08,710 --> 00:18:10,240
I've already cleared out my thumb drive.

211
00:18:14,050 --> 00:18:17,860
Going to go ahead and click on the 132 Disk Imager program.

212
00:18:19,540 --> 00:18:21,940
And of course, because I'm on windows, it's going to prompt me to.

213
00:18:23,730 --> 00:18:27,090
That I'm installing an application outside of the Microsoft Store.

214
00:18:27,390 --> 00:18:28,020
That's fine.

215
00:18:28,020 --> 00:18:29,370
Go ahead and click on Install.

216
00:18:31,310 --> 00:18:36,050
And in a moment, you'll go through the prompts of the disk imager software.

217
00:18:37,900 --> 00:18:40,750
And this is also under the new GPL license.

218
00:18:43,230 --> 00:18:44,620
So you have to accept the agreement.

219
00:18:44,650 --> 00:18:46,620
Give it a place where you want it to install.

220
00:18:47,790 --> 00:18:49,860
And I'm not just going to follow the prompts through it.

221
00:18:49,860 --> 00:18:56,520
I'm going to let that install and I'm not going to give you the read me for the purposes of this demo,

222
00:18:56,520 --> 00:18:58,260
and we're going to go ahead and run the program.

223
00:18:59,760 --> 00:19:02,580
It's going to make it a little bit bigger so I can actually see what we're doing here.

224
00:19:03,180 --> 00:19:04,410
And we're going to.

225
00:19:06,930 --> 00:19:09,030
Open up the ISO we just downloaded.

226
00:19:37,680 --> 00:19:40,230
We actually generate a SHA256 hash.

227
00:19:43,960 --> 00:19:45,250
So these are the basic steps.

228
00:19:45,250 --> 00:19:50,650
You plug in a USB drive, make sure you remember the drive letter, which it was connected to, and

229
00:19:50,650 --> 00:19:51,820
choose the ISO file.

230
00:19:51,820 --> 00:19:54,970
And once you click on that, you'll click on the right button.

231
00:19:55,720 --> 00:20:01,870
And once you've burned your image, you want to go ahead and safely eject the USB drive.

232
00:20:11,990 --> 00:20:17,180
I'm going to do mine and you not burden because I just want to show some variety here.

233
00:20:18,380 --> 00:20:19,760
Go ahead and install that.

234
00:20:20,910 --> 00:20:21,380
Right click.

235
00:20:21,380 --> 00:20:21,980
Yes.

236
00:20:24,410 --> 00:20:28,940
And we're going to click on the right place.

237
00:20:28,940 --> 00:20:30,290
We have the disk image.

238
00:20:32,950 --> 00:20:34,780
Which in my case is on the drive.

239
00:20:35,140 --> 00:20:40,120
Just make sure you wherever you save it out, you remember where it is and click open.

240
00:20:40,480 --> 00:20:42,610
And then I'm going to.

241
00:20:43,980 --> 00:20:46,020
Burn that to the USB drive.

242
00:20:50,160 --> 00:20:51,060
That I connected.

243
00:20:53,540 --> 00:20:59,240
Keep in mind, if you're using a USB hub, you may have some issues with the drive.

244
00:21:00,080 --> 00:21:01,280
So make sure that your.

245
00:21:03,100 --> 00:21:04,420
Burning to the right drive.

246
00:21:04,420 --> 00:21:04,720
See you.

247
00:21:04,720 --> 00:21:07,480
Avoid messing up your workstation.

248
00:21:15,700 --> 00:21:21,160
Now we've got our image selected and the correct drive letter selected will select.

249
00:21:21,160 --> 00:21:26,410
Okay, and it will go through some process of downloading the files if it needed to.

250
00:21:26,680 --> 00:21:29,650
Or in this case, it's just going to extract and copy the files.

251
00:21:29,980 --> 00:21:35,170
It's going to install the bootloader, and we'll come back when it's complete.

252
00:21:41,760 --> 00:21:44,880
Keep in mind, the installation to a thumb drive will take some time.

253
00:21:45,540 --> 00:21:53,910
You can also install it to a CD or DVD if needed, but the thumb drive will be the much faster option

254
00:21:54,780 --> 00:21:59,430
and is the recommended option as well by the Coward Linux team.

255
00:22:02,390 --> 00:22:10,790
So if you want to do the same thing on Linux, you'll have to go into the D d command and you'll have

256
00:22:10,790 --> 00:22:13,790
to be running as route to be able to execute that command with sudo.

257
00:22:15,110 --> 00:22:16,670
You can do this from.

258
00:22:17,940 --> 00:22:20,590
Mac OS or another one X distribution.

259
00:22:21,190 --> 00:22:28,510
You'll have to use the disk command to figure out which disks you have available to make sure that you

260
00:22:28,960 --> 00:22:33,550
pick the correct partition so you'll get an output similar to the one below.

261
00:22:40,500 --> 00:22:47,370
So once you're going to do it with Kali Linux or any other Linux distribution, you can do the.

262
00:22:48,610 --> 00:22:52,750
You plug in the drive and you'll have to enter the pseudo AV disk command one more time.

263
00:22:53,830 --> 00:22:56,260
Because it doesn't update in real time.

264
00:22:57,640 --> 00:23:00,100
And this is the command below that you'll type.

265
00:23:00,100 --> 00:23:06,160
If you want to create a bootable thumb drive, you'll use the DVD.

266
00:23:06,370 --> 00:23:08,020
The DVD command.

267
00:23:08,800 --> 00:23:15,100
I asked, is the input file, which equals the name of the file that you downloaded or the ISO OS is

268
00:23:15,100 --> 00:23:21,940
the output file and this is the path the slash DV slash SDB two.

269
00:23:21,940 --> 00:23:24,370
Or it might be something different in your case.

270
00:23:24,370 --> 00:23:28,660
And then BZ stands for the block size that you wanted to write to.

271
00:23:29,530 --> 00:23:34,300
You can leave it to 512 K and that should be just fine.

272
00:23:40,580 --> 00:23:48,800
So once you're going to start booting your system or your Kelly Linux system on a hard drive, you'll

273
00:23:48,800 --> 00:23:56,630
either have to have a bootable DVD or a USB and you have to go into the BIOS while booting.

274
00:23:57,770 --> 00:24:04,610
Or you might also have it called the UFC and it may be depending on the type of machine you're working

275
00:24:04,610 --> 00:24:09,440
on your press, either the F2 or the an F9 key to go into the bios.

276
00:24:09,800 --> 00:24:16,730
So the BIOS or the EFI on the newer machines handles all the boot process and it can be configured through

277
00:24:17,390 --> 00:24:22,370
the setup software so you can change which version you want to boot into.

278
00:24:23,090 --> 00:24:25,310
You'll notice some different options in the menu here.

279
00:24:25,640 --> 00:24:32,000
It can be either live mode or live USB with persistence, even encrypted persistence.

280
00:24:32,870 --> 00:24:36,970
You could also do the install or the graphical install options as well.

281
00:24:43,240 --> 00:24:43,450
All right.

282
00:24:43,450 --> 00:24:49,460
Now let's talk about another way to install Kali Linux, which is done through something called VirtualBox.

283
00:24:49,860 --> 00:24:58,360
VirtualBox software is from Oracle and it also requires something called Intel virtualization software

284
00:24:58,360 --> 00:24:59,800
or Intel VHD.

285
00:25:00,370 --> 00:25:09,610
If you have an Intel based machine or CPU, you can typically install VirtualBox without any problems

286
00:25:09,610 --> 00:25:13,870
and be able to virtualize your Kali Linux installation.

287
00:25:20,750 --> 00:25:23,030
So let's go over to the virtual box website.

288
00:25:31,660 --> 00:25:33,190
And we can see we're redirected to.

289
00:25:34,340 --> 00:25:35,030
Oracle.

290
00:25:35,030 --> 00:25:38,210
And there are some prebuilt virtual machines.

291
00:25:38,210 --> 00:25:42,470
If you're working in other areas or one X, you want to click on the blue button here and you want to

292
00:25:42,470 --> 00:25:43,340
click Download.

293
00:25:43,670 --> 00:25:45,380
VirtualBox 6.1.

294
00:25:45,380 --> 00:25:51,560
Now you'll want to choose the particular distribution or the particular download for your type of architecture.

295
00:25:51,860 --> 00:25:57,650
Now, if you're running on Windows, you'll click on Windows, OSX, obviously, or OSX, and then you'll

296
00:25:57,650 --> 00:25:59,120
have your Linux distributions.

297
00:25:59,480 --> 00:26:03,860
And they also include SHA256 check sums as well.

298
00:26:04,640 --> 00:26:05,690
Now one more thing.

299
00:26:05,990 --> 00:26:10,790
Depending on your hardware, you may need this VirtualBox extension pack.

300
00:26:11,180 --> 00:26:17,870
So if you have if you want to be able to add USB devices to your virtual machines as well as have newer

301
00:26:17,870 --> 00:26:25,520
machines such as that have nvme drives the nonvolatile disks.

302
00:26:25,520 --> 00:26:31,640
So you want to make sure that you have whatever you need and they also have the user manual as well.

303
00:26:32,000 --> 00:26:34,220
So I'm going to go ahead and click on the download.

304
00:26:36,380 --> 00:26:38,510
And we'll go ahead and save this virtual box.

305
00:26:38,510 --> 00:26:44,710
6.1.1, though, once you have it installed, you'll be able to update it just fine.

306
00:26:44,720 --> 00:26:46,340
I happen to have it already installed.

307
00:26:53,300 --> 00:26:54,850
We're going to go ahead and start menu.

308
00:26:55,120 --> 00:26:58,510
And once you're installed, you can type in VirtualBox.

309
00:26:59,770 --> 00:27:00,820
In the search for.

310
00:27:02,240 --> 00:27:04,550
And you'll get something like this, your main screen.

311
00:27:04,850 --> 00:27:08,270
If you've not installed it before, you won't have any virtual machines.

312
00:27:08,270 --> 00:27:09,440
You'll have a blank screen.

313
00:27:11,540 --> 00:27:14,420
In my case, I have several other virtual machines already installed,

314
00:27:18,050 --> 00:27:21,400
so I have many more things here than you will at the start.

315
00:27:21,410 --> 00:27:25,700
So we'll notice I have clients already running, but if I want to

316
00:27:28,370 --> 00:27:34,070
look at some things like the Help File there's about Virtual Box, I can see what version I have installed.

317
00:27:34,520 --> 00:27:36,350
So I have 6.1.8.

318
00:27:36,350 --> 00:27:41,660
So you might want to update depending on the type of virtual machine or Linux that you're trying to

319
00:27:41,660 --> 00:27:42,110
run.

320
00:27:42,890 --> 00:27:48,320
You can do file check for updates and it will tell me that I'm already running in the most recent version

321
00:27:48,320 --> 00:27:49,370
of VirtualBox.

322
00:27:53,740 --> 00:27:57,310
So once I've installed it, then the main screen is going to like look like this.

323
00:27:57,670 --> 00:28:01,060
I'm going to click on the new option.

324
00:28:04,220 --> 00:28:09,260
Another machine, and I'm going to say new and I'm going to give it a name.

325
00:28:10,010 --> 00:28:11,600
I'm going to call it Kali Linux.

326
00:28:15,470 --> 00:28:19,640
We'll call it 2020 and you give it a path to the virtual machine.

327
00:28:19,640 --> 00:28:24,920
So in my case, I'm going to change something other than the default because I want to make sure that

328
00:28:24,920 --> 00:28:29,390
I have plenty of space on my system or the virtual machine.

329
00:28:33,890 --> 00:28:35,750
And I'm going to use this folder right here.

330
00:28:37,310 --> 00:28:42,170
And you want to pick the you can also pick your version of one X that you're running.

331
00:28:44,950 --> 00:28:45,530
My case.

332
00:28:45,530 --> 00:28:47,030
I want to get the latest kernel.

333
00:28:47,030 --> 00:28:50,360
So I'm going to go with the 2.6 and I hit next.

334
00:28:55,040 --> 00:29:00,290
So you can select the version as in 64 bit.

335
00:29:00,300 --> 00:29:01,700
It doesn't really matter at this point.

336
00:29:02,300 --> 00:29:08,850
You're going to load the ISO anyway, so the recommended amount of RAM is four gigabytes, of course.

337
00:29:09,440 --> 00:29:13,940
VirtualBox may say, you know, 768 or one gig is fine.

338
00:29:14,840 --> 00:29:15,380
So I'm going to.

339
00:29:15,440 --> 00:29:19,850
It gives me by default 1024 so I'm going to give it a little bit more RAM.

340
00:29:27,180 --> 00:29:28,860
So I'll bump it up to four gigs here.

341
00:29:28,860 --> 00:29:30,000
I'm moving the slider.

342
00:29:37,760 --> 00:29:41,870
Or you can alternatively type it in in the box on the right hand side.

343
00:29:42,920 --> 00:29:44,150
So four gigs are am.

344
00:29:46,230 --> 00:29:47,490
And then after that.

345
00:29:48,940 --> 00:29:54,580
I'm going to create a virtual hard disk because the space that carry Linux is actually going to consume

346
00:29:55,030 --> 00:29:55,870
on the system.

347
00:29:57,550 --> 00:29:58,930
And I'm going to create.

348
00:30:01,360 --> 00:30:03,670
And recommended size is eight gigabytes.

349
00:30:03,700 --> 00:30:09,610
I would say give it a little bit more, but I'll leave it the default version.

350
00:30:09,610 --> 00:30:16,660
And the nice thing about a virtual machine is they can dynamically allocate space as your hard drive

351
00:30:16,660 --> 00:30:17,290
fills up.

352
00:30:21,240 --> 00:30:23,460
So VDI is the default virtual box.

353
00:30:23,610 --> 00:30:30,600
If you're using VMware, it's VMD, K or Curium you if you're doing it on Linux or planning on moving

354
00:30:30,600 --> 00:30:31,140
it to a Linux.

355
00:30:31,140 --> 00:30:34,050
So we want it to be dynamic because we don't want to waste space.

356
00:30:34,050 --> 00:30:38,130
So it'll scale up and scale down the storage as needed.

357
00:30:46,990 --> 00:30:51,070
So then once we've created the virtual machine, you'll see this type of image.

358
00:30:51,100 --> 00:30:58,150
Let's go ahead and finish out the tutorial here and we'll leave it at eight gigabytes and we'll click

359
00:30:58,150 --> 00:31:00,580
Create and there we go.

360
00:31:00,610 --> 00:31:02,920
Now this, our newly created VM is right here.

361
00:31:07,110 --> 00:31:14,940
So now we've got our Kelly one X virtual box set up and we have our thumb drive selected.

362
00:31:15,390 --> 00:31:22,620
We're going to go ahead and go back to virtual box and we're going to click on.

363
00:31:30,080 --> 00:31:34,820
The Settings menu and we're going to go down to the storage tab and the storage tab.

364
00:31:34,820 --> 00:31:38,750
We're going to have to pick the file that we just created.

365
00:31:39,290 --> 00:31:42,680
So we're going to click Choose Virtual Optical, this file.

366
00:31:47,060 --> 00:31:52,910
When I click on the system tab and we want to make sure that the optical drive boots up first if we're

367
00:31:52,910 --> 00:31:54,110
doing it on a

368
00:31:56,990 --> 00:31:57,890
from the ISO.

369
00:32:05,970 --> 00:32:07,110
Go to settings.

370
00:32:12,700 --> 00:32:22,600
Go down to storage and we're going to in this case, going to choose or create the optical this file

371
00:32:22,660 --> 00:32:26,440
or to add a new one from the call we just downloaded.

372
00:32:28,450 --> 00:32:34,090
And there's the ISO and we're going to choose it and hit.

373
00:32:34,090 --> 00:32:34,570
Okay.

374
00:32:40,320 --> 00:32:44,000
And we want to make sure that we have the obstacle to boot first.

375
00:32:45,170 --> 00:32:47,630
So we'll go over to set back to settings.

376
00:32:52,150 --> 00:32:57,940
It is system and the optical is first after the floppy which you can disable the floppy if you want

377
00:32:57,940 --> 00:32:58,240
to.

378
00:32:58,720 --> 00:32:59,890
Really does not matter.

379
00:33:00,100 --> 00:33:03,970
Most of the rest of these options you can leave out the fault processor.

380
00:33:04,780 --> 00:33:10,030
We can give it more cores if you want it to run a little bit snappier depending on your hardware.

381
00:33:18,530 --> 00:33:21,380
So once we're going to install it, we can pick the.

382
00:33:24,120 --> 00:33:26,820
We can configure a lot of different parameters like network card.

383
00:33:27,120 --> 00:33:30,180
We're not going to do that here because we just want to go ahead and power it on.

384
00:33:30,630 --> 00:33:32,070
We're going to click Normal Start.

385
00:33:33,460 --> 00:33:35,080
And it's going to take a little bit of time.

386
00:33:36,650 --> 00:33:37,850
And then our live.

387
00:33:39,190 --> 00:33:40,840
Our boot menu should be coming up.

388
00:33:42,610 --> 00:33:43,970
It says session spawning.

389
00:33:44,600 --> 00:33:46,790
I'm going to go ahead and maximize the screen here.

390
00:33:47,330 --> 00:33:48,920
So starting a virtual machine.

391
00:33:50,600 --> 00:33:53,750
And this is the bias mode.

392
00:33:54,410 --> 00:33:57,020
You can do a graphical install or install.

393
00:34:00,590 --> 00:34:02,960
And there's even some advanced options.

394
00:34:07,600 --> 00:34:11,650
So we'll go ahead and do the graphical install in this case.

395
00:34:13,710 --> 00:34:20,310
I want to go ahead and make this a little bigger so it's a little bit easier to see.

396
00:34:23,360 --> 00:34:28,820
We can see our menu and we get to our first pop up for the installation.

397
00:34:28,820 --> 00:34:33,410
If you want to exit the virtual environment, you have to hit the right control button.

398
00:34:33,410 --> 00:34:35,120
And in the case of VirtualBox.

399
00:34:39,660 --> 00:34:45,810
So California's the only place that it is official to download the ISO for Kelly.

400
00:34:45,840 --> 00:34:50,400
Don't download it from anywhere else because these sites could contain malware.

401
00:34:50,670 --> 00:34:56,340
You always want to validate the SHA256 some of your download to make sure that you have confirmed the

402
00:34:56,340 --> 00:34:58,020
integrity of your ISO.

403
00:34:58,020 --> 00:35:02,190
If this doesn't match, try downloading again or use a different source.

404
00:35:02,190 --> 00:35:02,760
Because sometimes.

405
00:35:04,610 --> 00:35:10,610
You might just have a bad download and so your your SHA256, some may not match up.

406
00:35:11,780 --> 00:35:18,650
So if you're going to boot from a physical drive, you'll, you'll configure the bios to boot to the

407
00:35:18,650 --> 00:35:20,330
correct device.

408
00:35:20,600 --> 00:35:24,650
In some cases, it may just boot to that thumb drive once you plug it in.

409
00:35:25,550 --> 00:35:31,880
But if a thumb drive is disabled or its some other device is set to boot first like a CD or DVD, you

410
00:35:31,880 --> 00:35:32,840
may have to change it.

411
00:35:35,840 --> 00:35:38,030
So now we have our Kelly Lennox running.

412
00:35:42,360 --> 00:35:42,720
Okay.

413
00:35:42,720 --> 00:35:48,090
Now that we've got our image running notice down here, we have Kelly Linux and it'll ask us some different

414
00:35:48,090 --> 00:35:50,190
options for the installation process.

415
00:35:50,550 --> 00:35:53,940
So we'll click on English in my case, or whatever language you need.

416
00:35:54,270 --> 00:36:01,050
I'm in the U.S., so you'll pick whatever country is appropriate for your installation and what language

417
00:36:01,050 --> 00:36:02,670
that you want for the keyboard.

418
00:36:05,660 --> 00:36:07,730
And it's looking for the installation media.

419
00:36:13,370 --> 00:36:16,010
And it's going to go through some loading of some different components.

420
00:36:17,430 --> 00:36:22,140
And that is we have a menu at the bottom here because I'm in a virtual machine, so I can actually change

421
00:36:22,140 --> 00:36:23,700
preferences from here as well.

422
00:36:24,990 --> 00:36:26,310
But I'm not going to worry about it.

423
00:36:26,910 --> 00:36:32,160
As I hover over this, I can see any external devices, anything I plug into it.

424
00:36:33,400 --> 00:36:39,450
If I want the clipboard to be enabled for things like drag and drop the generally you can just let this

425
00:36:39,450 --> 00:36:42,000
go and everything will work just fine.

426
00:36:43,230 --> 00:36:51,030
I wanted that to be scaled mode so you know, which will make it a little bit better for a viewing angle.

427
00:36:51,660 --> 00:36:53,070
So that's important to understand.

428
00:36:53,070 --> 00:36:53,790
So first thing.

429
00:36:54,870 --> 00:36:55,800
Give it a hostname.

430
00:36:55,800 --> 00:36:57,330
You can you can leave it as a default.

431
00:36:57,330 --> 00:36:58,020
That's fine.

432
00:36:58,470 --> 00:37:00,150
Or you can call it something else.

433
00:37:00,450 --> 00:37:02,190
On if you're part of a domain name.

434
00:37:03,150 --> 00:37:09,360
That's great, but you don't need to do that for the the installation.

435
00:37:09,960 --> 00:37:14,790
So then you want to set up the some other account other than route.

436
00:37:14,790 --> 00:37:19,290
And that's one of the things that has changed in the new version of the next 2020.

437
00:37:19,620 --> 00:37:26,610
So this could be administrator or, you know, admin or anything you want.

438
00:37:26,610 --> 00:37:27,720
In this case, we'll just.

439
00:37:31,190 --> 00:37:32,450
We'll call this admin.

440
00:37:34,480 --> 00:37:36,760
And we'll continue to keep the username ad.

441
00:37:36,780 --> 00:37:39,490
Then you can you can put your full name if you want.

442
00:37:41,680 --> 00:37:45,970
See, notice that this is a one of the things you can't actually do admin because admins reserved for

443
00:37:45,970 --> 00:37:46,570
the system.

444
00:37:46,990 --> 00:37:51,490
So all will go back and will change this to sysadmin.

445
00:37:51,490 --> 00:37:53,140
You can always set up the account later.

446
00:37:53,410 --> 00:37:54,160
That's not a problem.

447
00:37:54,160 --> 00:37:56,680
You can create different settings.

448
00:37:56,950 --> 00:38:00,820
But notice this is the Debian installer or Debian depending on how you say it.

449
00:38:01,120 --> 00:38:03,550
It's just walking through step by step by step.

450
00:38:04,120 --> 00:38:08,470
So going to click on Continue and we'll change the name to let's say sysadmin.

451
00:38:09,250 --> 00:38:10,510
That sounds reasonable, right?

452
00:38:12,640 --> 00:38:17,830
I'll say sysadmin and you want to change a password.

453
00:38:18,880 --> 00:38:21,940
You want to make sure that you don't use an easily accessible password.

454
00:38:23,620 --> 00:38:28,900
The OS will allow you to use special characters and things like that.

455
00:38:28,900 --> 00:38:32,870
So make sure if you're concerned about security, that you want to use a strong password.

456
00:38:33,760 --> 00:38:36,790
My case, I'm just using it for demonstration purposes.

457
00:38:37,390 --> 00:38:39,910
You can click on the checkbox to show the password in the clear.

458
00:38:40,240 --> 00:38:45,490
If you want to be able to see that, but you have to enter the same password twice, otherwise it won't

459
00:38:45,490 --> 00:38:46,660
get past this stage.

460
00:38:47,440 --> 00:38:50,230
Your time zone that you're in.

461
00:38:50,230 --> 00:38:52,960
And then it'll set up the clock because timing is very important.

462
00:38:53,320 --> 00:38:55,690
And when extended, this can be a consideration.

463
00:38:55,690 --> 00:38:56,650
So it's going to go through.

464
00:38:56,950 --> 00:38:58,630
It's going to partition the disks.

465
00:39:00,820 --> 00:39:01,630
And you can tell it.

466
00:39:01,630 --> 00:39:01,900
Okay.

467
00:39:01,900 --> 00:39:03,730
I want to use the entire disk now.

468
00:39:03,970 --> 00:39:08,470
Of course, you wouldn't have to go through all of this if you download the VirtualBox image, which

469
00:39:08,470 --> 00:39:10,030
we'll do in another video.

470
00:39:10,330 --> 00:39:15,730
But I'm just showing you the steps that you would go through if you were doing a bare metal install.

471
00:39:16,390 --> 00:39:17,890
So we're going to use up the whole disk.

472
00:39:17,890 --> 00:39:21,790
In this case, just it says at a virtual box, hard disk.

473
00:39:22,270 --> 00:39:25,180
It's an SD is is the numbering scheme.

474
00:39:25,690 --> 00:39:30,670
So you want to make sure that if you're doing this on a live system and not a virtual machine, be careful

475
00:39:30,670 --> 00:39:33,040
of the the drive that you select.

476
00:39:34,660 --> 00:39:40,480
So I'm going to say, okay, so you can do all files in the partition or you can do you can customize

477
00:39:42,070 --> 00:39:42,820
if you want.

478
00:39:43,810 --> 00:39:47,530
So you'll have notice in this case we have in the T for partition.

479
00:39:47,530 --> 00:39:49,600
When we get into a partitioning, this will all make sense right now.

480
00:39:49,600 --> 00:39:55,690
You can just leave it as the default and then you click continue and it's going to.

481
00:39:57,280 --> 00:39:57,690
But I would.

482
00:39:58,900 --> 00:40:00,760
Allow you to choose some more options.

483
00:40:01,510 --> 00:40:03,790
I'm going to just say, okay, I want the x-t4.

484
00:40:03,850 --> 00:40:04,570
That's fine.

485
00:40:06,950 --> 00:40:08,000
I'm going to confirm.

486
00:40:19,170 --> 00:40:21,300
I want you made your partition selections.

487
00:40:21,630 --> 00:40:27,960
You're going to tell it to write the partition to discuss, and it's going to start installing the system.

488
00:40:27,960 --> 00:40:31,590
So that'll take a little while and we'll come back when it's complete.

489
00:40:33,530 --> 00:40:33,710
All right.

490
00:40:33,710 --> 00:40:38,900
A couple more things that Kelly Wallace will ask you if you want to use a proxy to access the outside

491
00:40:38,900 --> 00:40:39,100
world.

492
00:40:39,110 --> 00:40:44,990
Of course, if you're using maybe this at work on an actual engagement, you might have to set up a

493
00:40:44,990 --> 00:40:45,620
proxy.

494
00:40:46,010 --> 00:40:47,330
We're just going to leave this blank.

495
00:40:48,610 --> 00:40:56,170
And it's going to set up the app package manager, which is what most Debian based Linux distributions

496
00:40:56,560 --> 00:40:57,400
will use.

497
00:41:00,120 --> 00:41:05,370
And then it's kind of select and install different software and we'll come back when this is done.

498
00:41:08,770 --> 00:41:09,090
Okay.

499
00:41:09,090 --> 00:41:14,410
In the next part of the software installation, you can pick out what default desktop environment you

500
00:41:14,410 --> 00:41:14,860
want.

501
00:41:15,610 --> 00:41:19,510
You can pick gundam, KDE, light weight distribution.

502
00:41:19,780 --> 00:41:21,190
What tools do you want?

503
00:41:22,570 --> 00:41:25,270
There's the large default selection plus additional to.

504
00:41:25,280 --> 00:41:29,090
Also keep in mind that will be more different space.

505
00:41:29,110 --> 00:41:35,020
Of course, in this case we'll just pick on x, f, c, which is Kelly's default desktop environment.

506
00:41:35,320 --> 00:41:39,100
You might prefer some other type of environment in context, and that's perfectly fine.

507
00:41:40,020 --> 00:41:43,870
Okay, so we'll let that go and then we'll come back when that's done.

508
00:41:45,070 --> 00:41:48,340
I want you're done with Kelly Linux installing in VirtualBox.

509
00:41:48,820 --> 00:41:52,150
You'll be able to boot into it like you will a regular operating system.

510
00:41:52,450 --> 00:41:56,890
And we'll come back in the next lesson and we'll look at Linux fundamentals.

511
00:41:56,920 --> 00:42:02,080
Now, there's one other option I wanted to cover briefly before we get into.

512
00:42:04,860 --> 00:42:10,500
The next topic and that is calling Linux virtual machine images.

513
00:42:13,160 --> 00:42:17,210
So if you don't want to go through all the setup and you just want to get up and running with Kali Linux

514
00:42:17,210 --> 00:42:24,350
very quickly, you can go back to the Kelly Lennox homepage and you can go to downloads, download common

515
00:42:24,370 --> 00:42:30,860
accents for all the way to the bottom down here where it says VMware and Virtual Boxes.

516
00:42:31,040 --> 00:42:34,160
Since we're running a virtual box, we're going to go ahead and pick the 64 bit.

517
00:42:34,580 --> 00:42:39,050
You notice the link says available on the offensive security theme download page.

518
00:42:39,320 --> 00:42:44,720
So to click on this link and notice it redirects you to the offensive security download option.

519
00:42:45,500 --> 00:42:49,480
So you can click on download prebuilt virtual box images.

520
00:42:49,490 --> 00:42:50,900
You can do it, of course, with the torrent.

521
00:42:51,140 --> 00:42:55,820
It also has Hyper-V for if you want to run it through Microsoft, but in this case will click on a virtual

522
00:42:55,820 --> 00:42:59,510
box and you click on the 64 bit download.

523
00:42:59,510 --> 00:43:08,780
Notice that it downloads it as a ova file and and be 64 over a file otherwise known as the Open Virtualization

524
00:43:08,780 --> 00:43:09,890
Format Archive.

525
00:43:10,370 --> 00:43:18,680
So this can be downloaded if you just want to download an already pre-built Kelly Linux image and you

526
00:43:18,680 --> 00:43:20,830
don't want to have to mess with any of the installation.

527
00:43:20,900 --> 00:43:23,330
This is only for in a virtual machine.

528
00:43:23,930 --> 00:43:28,730
If you want to do it through a physical machine that you install on, you'll do that with the thumb

529
00:43:28,730 --> 00:43:31,880
drive or the DVD drive or whatever have you.

530
00:43:34,670 --> 00:43:39,320
So that's it for this first chapter and we'll see you in the next one.
