Now that you've seen that you might be thinking wow that was too easy.

2

That's all it takes to install and remove packages of Linux.

3

I don't even have to go to the Internet and find them.

4

Just find them for me.

5

Yes.

6

Is that something that you might notice wondering but what do these packages come from.

7

How does candy or anything else for that matter know where to go and look for these packages.

8

They look in something called depositories and depositories are storage locations from which your software

9

packages can be retrieved and installed.

10

So Gadi for example or Debian or anything else for that matter it would have the most storage location

11

once you issue the ABT get command your Linux box will go into that location try and find the package

12

and if it does it will download it and install it for you.

13

However sometimes you try to install the baggage and Kelly can't find it and the default repositories.

14

So what do you do first let's have a look at what these things look like.

15

They're usually on the EDC slash AP

16

and these are the two you are as are the two locations where you can go and find the packages that I

17

want to install.

18

You could actually master this using your web browser.

19

Let's say I want to update my system.

20

I can do that using the EPG get update.

21

Now that will take once or just speed things up a bit.

22

Now ever want to do a full distribution upgrades I can do that.

23

Apt get upgrade.

24

See all of that.

25

These are all software packages that will be upgraded if I continue with these commands.

26

Is poor exploitation of the compromise Linux host.

27

Chances are that you won't get non-truth access and you want to find a vulnerability that will give

28

you access.

29

This usually involves finding and exploiting vulnerable software.

30

You might also come across situations where the Linux box you broke into is not connected to the Internet.

31

Let's say you're unethical engagement for.

32

I don't know a bank.

33

They invite you to come in and plug into their internal network as an employee and see if you can hack

34

anything on that internal network.

35

You managed to get into a Linux box and you find out that it's not the next to the Internet when you

36

still want to use it as a stepping stone to try and get to other systems.

37

To do that you need to install some packages on it but it's not connect to the Internet that's off line.

38

So what do you do in this case for both situations.

39

You could use the package commands and this is useful in multiple situations.

40

Sometimes software cannot be found in depositories Nessus for example if you try to install it using

41

the ABC get commands you will not be able to find it.

42

You'll find that on the Nessus website and you'll notice that it ends with a thought that the the the

43

extension which means that software for Linux Debian unlike FBD However we need to know that the package

44

does not take care of the penances for us.

45

So if a package needs and dependencies we'll have to take care of that ourselves to get back to the

46

Xenogears that we've discussed in our both exploitation to find versions of installed applications and

47

hope that you are going to want an all out dated vulnerable one.

48

You can do that using the deep package minus and commands to install the package.

49

Let's say I want to install Nessus for example.

50

After downloading it I can do that using the package minus my commands.

51

And to remove the baggage.

52

You can do that using the package minus commands.

53

Now you might be wondering what I just said that the Linux system was off line.

54

And how am I saying that I can install Nessus after downloading it.

55

That's going to be for another chapter in another chapter we're going to be learning how to download

56

stuff on our Candy machine.

57

And then how we can use our Gadi machine as a server to upload stuff from our galley to the victim machine.

58

Now let's not worry too much about it let's just assume that you somehow managed to get the Nessus package

59

on the victim machine.

60

And you can use that package command to install and remove it.

61

Now remember these are all situations that happen in ethical hacking engagements.

62

Having said that and I think that having an agent you want to make sure that you have the permission

63

to install and remove softer off your clothing on the machine.

64

So mission for the section on your Gadi machine install files ilah on your Windows machine activate

65

FTB.

66

If you don't know how to do that.

67

We explain that in our hacking for beginners course go there and he knew that section on hacking for

68

beginners and using structures on those videos activate FTB on your Windows machine.

69

Then from an open file Zilah and next year is over on Windows.

70

So I had to upload and download some files.

71

Then on your candy machine download and install Nessus.

72

Once you're done we can move onto the next section.
