1

00:00:00,729  -->  00:00:05,571
In the previous video, we have done
creating a topology like this.

2

00:00:05,778  -->  00:00:13,675
So here we have ubuntu server inside virtualbox.
This ubuntu server is connected to internet,

3

00:00:13,919  -->  00:00:20,950
connected to router inside gns3, and
also connected to host os or our laptop.

4

00:00:21,575  -->  00:00:30,933
If you remember, we also able to remote the ubuntu
server from our laptop using ssh. Let’s check it,

5

00:00:32,650  -->  00:00:36,002
here, we are in the mac os terminal,

6

00:00:36,085  -->  00:00:43,717
but this is the ubuntu prompt. This is means
that we remote the ubuntu server from our laptop.

7

00:00:44,148  -->  00:00:48,442
This ubuntu server will used
to do network automation.

8

00:00:48,736  -->  00:00:53,607
we will write a network automation
script here in the ubuntu server.

9

00:00:54,193  -->  00:00:59,538
So we need to make sure that python
is installed in the ubuntu server.

10

00:01:00,079  -->  00:01:07,436
Let’s type pyt and then tab. Here we
can see that we already have python3.

11

00:01:07,919  -->  00:01:16,196
Let’s enter here, okay this is
python version 3.8.2. Let’s exit.

12

00:01:17,370  -->  00:01:25,878
To write the python script, we have multiple
way. First, we can use text editor from ubuntu,

13

00:01:25,878  -->  00:01:35,784
which is nano. Let’s try, nano and then
the file name, let’s say script1.py.

14

00:01:37,113  -->  00:01:46,431
Okay we are in the nano text editor, let’s write
python script here, let’s say print hello python.

15

00:01:47,930  -->  00:01:50,916
Print hello world, and others.

16

00:01:53,353  -->  00:02:06,247
Save this, ctrl + x, y, enter. Let’s ls here,
here we can see that we have script1.py,

17

00:02:06,662  -->  00:02:08,379
let’s run this script.

18

00:02:08,593  -->  00:02:17,179
Python script1.py. here we can see that
we get hello python and hello world.

19

00:02:17,638  -->  00:02:25,447
Another way, we can use sublime text.
Sublime text is a desktop text editor,

20

00:02:25,718  -->  00:02:32,859
this is means that the sublime text is
running on host os, not in the guest os,

21

00:02:33,359  -->  00:02:40,768
because the ubuntu server is cli, so we can
not install sublime in the ubuntu server.

22

00:02:41,731  -->  00:02:47,856
So now the question is, how we
can edit the script on our laptop,

23

00:02:47,856  -->  00:02:51,979
but the script will also
saved on the ubuntu server.

24

00:02:52,684  -->  00:02:57,938
This is what we are going to learn
in this video, let’s just start.

25

00:02:58,364  -->  00:03:03,582
To do that, we need to install
additional package in sublime text.

26

00:03:04,753  -->  00:03:10,768
Here in the sublime text, type ctrl + shift + p.

27

00:03:11,513  -->  00:03:19,925
Or if you use mac, you need to type command
+ shift + p. But in the windows or linux,

28

00:03:19,925  -->  00:03:24,043
we need to type ctrl + shift + p.

29

00:03:26,284  -->  00:03:32,288
Here let’s type install and then
choose install package control.

30

00:03:32,851  -->  00:03:35,870
You can click here or just enter.

31

00:03:36,490  -->  00:03:44,179
Wait for a minute. Okay here we get a message that
package control was successfully installed.

32

00:03:45,798  -->  00:03:53,545
Ctrl + shift + p again, here let’s
choose package control: install package.

33

00:03:56,451  -->  00:04:00,944
Here we can see some package that
we can install in sublime text.

34

00:04:03,947  -->  00:04:12,238
Let’s search for sftp. This is the package
that we are going to install. Click here.

35

00:04:15,582  -->  00:04:20,796
Okay here we get a message that
sftp is successfully installed.

36

00:04:21,536  -->  00:04:29,711
Now let’s setup the sftp. First, we need
to open empty folder in the sublime.

37

00:04:32,295  -->  00:04:39,032
File open, and here we can
choose the empty folder.

38

00:04:56,267  -->  00:05:05,413
Right click here, here we have a choice
sftp or ftp. Choose map to remote.

39

00:05:05,828  -->  00:05:10,185
Here we need to define the
information about ubuntu server.

40

00:05:10,993  -->  00:05:20,185
So the host is the ip address of
ubuntu server, which is 192.168.56.2.

41

00:05:23,175  -->  00:05:31,305
and then the username is ubuntu, and then
here for the password, let’s remove the slash.

42

00:05:31,690  -->  00:05:38,825
This slash means comment. And then here
let’s type the password of ubuntu server.

43

00:05:39,175  -->  00:05:42,797
I will change the password of ubuntu server first.

44

00:05:52,947  -->  00:05:58,173
Let’s back to sublime text.
And type the password here.

45

00:06:01,398  -->  00:06:06,133
And then remote path, this is
the path in the ubuntu server.

46

00:06:06,507  -->  00:06:12,327
so later, the local path will be synchronize
to the path in the ubuntu server.

47

00:06:12,850  -->  00:06:17,659
Let’s say I will synchronize to the
home directory in the ubuntu server.

48

00:06:18,074  -->  00:06:24,391
Let’s type pwd here. The path is /home/ubuntu.

49

00:06:27,015  -->  00:06:30,549
So here let’s put /home/ubuntu.

50

00:06:33,735  -->  00:06:39,676
You can see the configuration here and change
some configuration that you want to change.

51

00:06:41,760  -->  00:06:45,739
In this case, I want to change this configuration,

52

00:06:46,193  -->  00:06:52,891
upload on save. This is means that the sublime
will upload the file to the ubuntu server

53

00:06:52,891  -->  00:07:00,290
when we save the file. The default is
false, let’s change this become true.

54

00:07:02,187  -->  00:07:11,466
We have done here, save this. Right
click here in the folder, sftp,

55

00:07:11,685  -->  00:07:19,333
synchronize remote to local. This is means we
synchronize from the ubuntu server to our laptop.

56

00:07:21,342  -->  00:07:29,840
Here we can see that we connect to
192.168.56.2 as ubuntu, wait for a minute.

57

00:07:35,690  -->  00:07:41,817
Here we can see some file from ubuntu
server that will synchronized to our laptop.

58

00:07:43,936  -->  00:07:51,351
Oh I am sorry, this is cancel when I
click here. Right click again, sftp,

59

00:07:51,351  -->  00:07:54,236
and then synchronize remote to local

60

00:07:54,771  -->  00:07:59,055
Here we can see some file that will
downloaded to our laptop.

61

00:07:59,589  -->  00:08:10,265
But here we can see some file that we don’t need in our
laptop, .ssh/config, .ssh/known_hosts and others.

62

00:08:10,816  -->  00:08:13,516
So in this case, I will choose no.

63

00:08:16,073  -->  00:08:24,256
Here in the sftp configuration, we have
ignore regex. We can put file or directory

64

00:08:24,256  -->  00:08:34,539
that we don’t want to synchronize here. In
this case, we want to ignore .ssh. save.

65

00:08:35,222  -->  00:08:47,676
Let’s try to synchronize again. Here we can see
that .ssh is not downloaded anymore. Yes here.

66

00:08:48,319  -->  00:08:54,893
Okay we have done, here we can
see that now we have script1.py,

67

00:08:55,285  -->  00:08:59,533
this is the script that we write
in the ubuntu server before.

68

00:09:00,000  -->  00:09:02,156
Let’s try to edit this,

69

00:09:02,673  -->  00:09:10,529
Print hello java. Save this,
here we can just cancel it.

70

00:09:12,165  -->  00:09:14,076
Back to the terminal,

71

00:09:16,771  -->  00:09:25,942
ls, here we can see that we only have script1.py,
may be some of you have a question,

72

00:09:26,200  -->  00:09:32,101
why when we synchronize in the sublime,
we get a lot of file?

73

00:09:32,677  -->  00:09:44,848
This is because, file that started by dot is hidden file, to
see hidden file in ubuntu, we can use ls -a.

74

00:09:45,724  -->  00:09:52,876
Okay here we can see many file that
started by dot, this is means hidden file.

75

00:09:53,793  -->  00:09:57,060
Okay now let’s run script1.py,

76

00:10:01,204  -->  00:10:05,494
here we can see that now we have hello java.

77

00:10:05,873  -->  00:10:10,922
Remember that we add hello java
from our laptop in the sublime text.

78

00:10:11,313  -->  00:10:19,596
So now when we edit from sublime text, the file
will be saved automatically on ubuntu server.

79

00:10:20,135  -->  00:10:27,951
Let’s try to create new file from
sublime text. Let’s say script2.py,

80

00:10:29,804  -->  00:10:40,368
write a python script here, let’s say print
hello java and then print hello python. Save.

81

00:10:40,667  -->  00:10:48,819
Now let’s go to ubuntu, ls, here
we can see that we have script2.py,

82

00:10:50,000  -->  00:10:55,294
let’s run this script, python script2.py.

83

00:10:56,073  -->  00:11:00,288
Okay here we get hello java and hello python.

84

00:11:00,879  -->  00:11:04,916
So now we can edit the script in the sublime text,

85

00:11:05,205  -->  00:11:09,881
and the script will be automatically
saved in the ubuntu server.

86

00:11:10,576  -->  00:11:15,469
I think enough for this video. In the
next video, we are going to learn

87

00:11:15,469  -->  00:11:18,575
how to install package in python.

88

00:11:18,971  -->  00:11:22,774
Thank you for watching and see you on the next video.
