2
00:00:02,300 --> 00:00:06,200
Friends, here our concept is, how to transfer a file from local server to

3
00:00:06,200 --> 00:00:10,200
remote server and vice versa, using paramiko of Python.

4
00:00:10,200 --> 00:00:13,400
See, simply you're having one local server and you're

5
00:00:13,400 --> 00:00:15,500
having one remote server, just assume that.

6
00:00:15,500 --> 00:00:18,400
Now, suppose some file is there on your local server,

7
00:00:18,400 --> 00:00:20,800
I need to transfer this file to your remote server,

8
00:00:20,800 --> 00:00:23,000
or some file is there on your remote server and I need

9
00:00:23,000 --> 00:00:25,400
I need to download that file to your local server.

10
00:00:25,400 --> 00:00:27,800
And these all actions I want to perform with the

11
00:00:27,800 --> 00:00:30,000
help of paramiko of your Python,

12
00:00:30,000 --> 00:00:32,200
or simply Paramiko Module.

13
00:00:32,200 --> 00:00:35,500
Right. Let me explain this, with simply a simple code.

14
00:00:35,500 --> 00:00:39,000
So, friends already we know how your Paramiko Module

15
00:00:39,000 --> 00:00:41,000
is going to work from our previous video.

16
00:00:41,000 --> 00:00:46,700
Your Paramiko Module is going to work, by creating a SSH client, right?

17
00:00:46,700 --> 00:00:49,400
Anyway, you are using paramiko,

18
00:00:49,400 --> 00:00:52,100
that's why first of all you need to import that module.

19
00:00:52,100 --> 00:00:55,800
Then, you need to create SSH client, right?

20
00:00:55,800 --> 00:00:57,700
See, you know how to create SSH Client.

21
00:00:57,700 --> 00:00:59,394
There is a simple syntax for that.

22
00:00:59,300 --> 00:01:03,100
Then after that you need to add 'AutoAddPolicy'.

23
00:01:03,100 --> 00:01:11,000
This is just to avoid asking yes or no confirmation

24
00:01:11,000 --> 00:01:13,500
while connecting with your remote server at the very first time,

25
00:01:13,500 --> 00:01:18,200
or simply it is going to add to your known host on your local server.

26
00:01:18,200 --> 00:01:19,410
That's fine.

27
00:01:19,400 --> 00:01:22,500
Then after that, let me try to connect with your server.

28
00:01:22,500 --> 00:01:24,910
So you know how to connect with your server.

29
00:01:24,900 --> 00:01:29,600
So simply, using this SSH we created a connection with your

30
00:01:29,600 --> 00:01:33,200
remote server and whatever the connection we establish that

31
00:01:33,200 --> 00:01:38,500
will be pointed with the help of SSH object or SSH client.

32
00:01:38,500 --> 00:01:41,400
That's it. Now suppose,

33
00:01:41,400 --> 00:01:45,100
guys actually, I forgot to give this point in your previous video.

34
00:01:45,100 --> 00:01:49,500
That is once if your work is done with the help of your SSH client,

35
00:01:49,500 --> 00:01:52,600
finally you can also close your SSH client connection.

36
00:01:52,600 --> 00:01:56,800
Even though if you don't close, by default, it will be closed after some time.

37
00:01:56,800 --> 00:01:59,700
But it is better practice to close your SSH client

38
00:01:59,700 --> 00:02:03,300
once your work is done with your SSH client. That's fine.

39
00:02:04,100 --> 00:02:08,000
So using this SSH client you can execute some commands,

40
00:02:08,000 --> 00:02:11,600
but here our requirement is, we need to transfer a file to your

41
00:02:11,600 --> 00:02:14,900
remote server, or we need to download a file from your remote server.

42
00:02:14,900 --> 00:02:18,800
So for that you need to create from this SSH client

43
00:02:18,800 --> 00:02:23,300
one 'sftp' object or 'sftp' connection.

44
00:02:23,300 --> 00:02:26,200
So for that we have a simple syntax. See that.

45
00:02:26,200 --> 00:02:28,600
[no audio]

46
00:02:28,600 --> 00:02:29,800
Let me open my code.

47
00:02:29,800 --> 00:02:34,100
So, guys here I am going to write simply, 'sftp_client' object,

48
00:02:34,100 --> 00:02:36,578
or simply connection with the help of 'sftp'.

49
00:02:36,500 --> 00:02:40,600
'ssh.open_sftp()'. That's it.

50
00:02:40,698 --> 00:02:42,200
[No audio]

51
00:02:42,200 --> 00:02:45,700
Now, with the help of this fifth line, we are opening

52
00:02:45,700 --> 00:02:48,000
'sftp' connection with your remote server.

53
00:02:48,000 --> 00:02:51,600
Now using this 'sftp_client' object, or connection

54
00:02:51,600 --> 00:02:56,500
we can transfer a file, or we can download a file from your remote server.

55
00:02:56,500 --> 00:02:59,000
Now, see that. I am listing the operations which are

56
00:02:59,000 --> 00:03:00,800
there with your 'sftp_client'.

57
00:03:00,800 --> 00:03:03,800
[No audio]

58
00:03:03,800 --> 00:03:05,800
So, you are having different types of operations.

59
00:03:05,800 --> 00:03:07,800
Suppose if you want to change the ownership of a

60
00:03:07,800 --> 00:03:09,200
file on your remote server,

61
00:03:09,200 --> 00:03:14,000
then you can use 'sftp_client.changeownership'.

62
00:03:14,000 --> 00:03:19,000
Right. Likewise we have, suppose, current working directory. Right.

63
00:03:19,300 --> 00:03:21,000
Now see that? Let me go and show you that.

64
00:03:21,000 --> 00:03:22,300
And one more thing, here also

65
00:03:22,300 --> 00:03:25,300
once if your work is done with your 'sftp_client',

66
00:03:25,300 --> 00:03:29,100
you can also close this 'sftp' connection or session.

67
00:03:29,500 --> 00:03:32,900
So be clear, before 'sftp_client' don't close SSH,

68
00:03:32,900 --> 00:03:37,600
because your 'sftp' is depending on your SSH client object or connection.

69
00:03:38,200 --> 00:03:42,100
Right. See. Now, what I am doing is, first let me open my remote server.

70
00:03:42,100 --> 00:03:43,900
This is my remote server. Here

71
00:03:43,900 --> 00:03:44,900
I have some files.

72
00:03:44,900 --> 00:03:48,400
Let's say I'm having a file called, 'paramiko_download.txt'.

73
00:03:48,400 --> 00:03:49,800
In this we have some content.

74
00:03:49,800 --> 00:03:54,600
I need to download this file on my local server with the help of Python paramiko

75
00:03:54,600 --> 00:03:58,660
Then simply syntax is, see that, 'sftp_client.get',

76
00:03:58,660 --> 00:04:01,900
your remote server file with complete path.

77
00:04:01,900 --> 00:04:03,300
Actually, that is a good practice.

78
00:04:03,300 --> 00:04:07,310
Now, let me take complete path. '/home/ec2-user',

79
00:04:07,300 --> 00:04:08,600
then this file name, right?

80
00:04:08,600 --> 00:04:13,800
See that how I am going to write, source is, 'ec2-user/', your file.

81
00:04:13,800 --> 00:04:15,800
Then on the local host,

82
00:04:15,800 --> 00:04:19,500
so for 'get' you have a source file and then destination.

83
00:04:19,500 --> 00:04:22,736
'get' means downloading a file from remote server.

84
00:04:22,736 --> 00:04:24,300
Now suppose,

85
00:04:24,300 --> 00:04:34,400
I am directly giving, 'paramiko_downloaded_file.txt'

86
00:04:34,400 --> 00:04:37,500
See, I'm not giving complete path. Just I am giving the file name

87
00:04:37,500 --> 00:04:40,100
in which you want to store this remote file content.

88
00:04:41,100 --> 00:04:42,895
So, whenever if you run your Python script,

89
00:04:42,800 --> 00:04:45,000
in which location this Python script is there,

90
00:04:45,000 --> 00:04:46,610
there it is going to download.

91
00:04:46,600 --> 00:04:49,700
Instead of that if you want to store in any required path,

92
00:04:49,700 --> 00:04:52,200
then you have to provide complete path on your Windows Server.

93
00:04:52,200 --> 00:04:55,700
Anyway, as of now I am running this code from my Windows server.

94
00:04:55,700 --> 00:05:00,500
Right. See in our case, local server, remote server

95
00:05:00,500 --> 00:05:02,900
and our remote server is Linux

96
00:05:02,900 --> 00:05:04,705
and local server I am taking as Windows.

97
00:05:04,700 --> 00:05:07,300
Any combination will work. Right.

98
00:05:07,300 --> 00:05:10,300
Now see that. Let me save it and run it.

99
00:05:10,324 --> 00:05:14,810
[no audio]

100
00:05:14,800 --> 00:05:19,300
It's done. Let me go to open my location where we have the server,

101
00:05:19,300 --> 00:05:22,010
I mean this script.

102
00:05:22,000 --> 00:05:24,838
'paramiko_download_file.txt'.

103
00:05:24,800 --> 00:05:27,800
'paramiko_downloaded_file.txt'.

104
00:05:27,800 --> 00:05:29,900
So, this is the file just now we downloaded.

105
00:05:29,900 --> 00:05:31,800
[No audio]

106
00:05:31,800 --> 00:05:34,050
So guys, this is the way we can download.

107
00:05:34,800 --> 00:05:37,000
Right. Now one more thing,

108
00:05:37,600 --> 00:05:42,210
I want to download this file, but without mentioning this path.

109
00:05:42,200 --> 00:05:46,900
See, sometimes you need to move into different location over 'sftp',

110
00:05:46,900 --> 00:05:49,800
then there you have to download the file without mentioning the path.

111
00:05:49,800 --> 00:05:52,300
Yes, we can do that also. Very simple. See that.

112
00:05:53,300 --> 00:05:55,800
Before going to download your file,

113
00:05:56,300 --> 00:06:00,700
what we have to do is, we need to move our 'sftp' connection,

114
00:06:00,700 --> 00:06:04,409
or we need to change the location of your 'sftp_client' object

115
00:06:04,400 --> 00:06:08,200
on your remote server by using 'chdir' operation.

116
00:06:08,100 --> 00:06:12,900
So, now I am going to suppose, '/etc' location,

117
00:06:12,900 --> 00:06:15,400
yeah, let me take simply '/home/ec2-user'.

118
00:06:17,100 --> 00:06:22,800
Right. Now, let me simply print current location pointed by your 'sftp_client'.

119
00:06:22,800 --> 00:06:26,100
So simply you can get current working directory with this syntax.

120
00:06:26,100 --> 00:06:27,300
See the output.

121
00:06:27,300 --> 00:06:30,409
[no audio]

122
00:06:30,400 --> 00:06:33,000
Now your 'sftp' is pointing to this location.

123
00:06:33,000 --> 00:06:35,900
So in this location whatever the file you are having, that file

124
00:06:35,900 --> 00:06:38,100
without mentioning complete path, you can download

125
00:06:38,100 --> 00:06:42,800
because already your 'sftp_client' object is pointing to this path,

126
00:06:42,800 --> 00:06:46,800
that's why now I am going to download 'sftp_client.get'.

127
00:06:46,800 --> 00:06:48,800
Let me take some other file here.

128
00:06:48,800 --> 00:06:52,700
So, let's say I'm having 'demo.txt' file from 'ec2-file',

129
00:06:52,700 --> 00:06:53,787
I won't to download that.

130
00:06:53,700 --> 00:06:57,700
Directly on remote server I have a file called 'demo.txt',

131
00:06:57,700 --> 00:07:02,000
that file I want to download it into let's say, desktop location.

132
00:07:02,000 --> 00:07:04,600
[No audio]

133
00:07:04,600 --> 00:07:05,900
Let me take complete path.

134
00:07:05,900 --> 00:07:09,810
[no audio]

135
00:07:09,800 --> 00:07:12,610
I want to download into desktop location.

136
00:07:12,600 --> 00:07:19,100
let's say, 'downloaded file.txt', with this file name. And

137
00:07:19,100 --> 00:07:20,900
be clear we are working with Windows,

138
00:07:20,900 --> 00:07:21,800
I mean local server.

139
00:07:21,800 --> 00:07:25,300
We are downloading our file to this Windows Server.

140
00:07:25,300 --> 00:07:27,448
That's why whenever if you are mentioning a path,

141
00:07:27,400 --> 00:07:30,000
it is always good to mention, '//' in your path

142
00:07:30,000 --> 00:07:32,200
whenever if you are providing your path manually.

143
00:07:33,200 --> 00:07:34,909
Let me save it and run it.

144
00:07:34,900 --> 00:07:39,600
[No audio]

145
00:07:39,600 --> 00:07:40,909
Yes, it has been done.

146
00:07:40,900 --> 00:07:44,964
Let me go to my desktop location and see there.

147
00:07:44,900 --> 00:07:47,100
Any file called, 'downloaded_file'?

148
00:07:47,100 --> 00:07:50,000
Yeah, see that. That's it.

149
00:07:50,000 --> 00:07:53,700
So, this is the way how we can mention complete path on your local server

150
00:07:53,700 --> 00:07:56,700
or how to mention complete path on your remote server.

151
00:07:56,700 --> 00:07:58,600
Without mentioning your complete path

152
00:07:58,600 --> 00:08:00,077
if you want to download a file,

153
00:08:00,000 --> 00:08:05,200
first change your 'sftp_client' pointing path on your remote server

154
00:08:05,200 --> 00:08:07,600
by using change directory. That's it.

155
00:08:07,600 --> 00:08:09,100
[No audio]

156
00:08:09,100 --> 00:08:12,000
Right. So guys, this is the way how you can download.

157
00:08:12,000 --> 00:08:15,710
Now, I want to transfer a file from local server to remote server.

158
00:08:15,700 --> 00:08:19,100
It's very simple. Now let me comment all these things.

159
00:08:19,100 --> 00:08:24,700
[No audio]

160
00:08:24,700 --> 00:08:27,810
Suppose in the current location I have some file.

161
00:08:27,800 --> 00:08:30,990
Let me transfer our Python script itself.

162
00:08:30,900 --> 00:08:36,600
'sftp_client.put', on your remote server into this location.

163
00:08:36,600 --> 00:08:38,100
[No audio]

164
00:08:38,100 --> 00:08:41,700
Sorry, source is our local server, right.

165
00:08:41,700 --> 00:08:44,700
So, let's say some, any script name called,

166
00:08:45,700 --> 00:08:47,500
yeah, I will take this Python script only.

167
00:08:47,500 --> 00:08:49,299
[no audio]

168
00:08:49,299 --> 00:08:54,909
'transfer_files.py'. So on the current location we have this file.

169
00:08:54,900 --> 00:08:56,299
So, this I want to move,

170
00:08:56,299 --> 00:09:00,900
I mean I want to transfer to your remote server, into this location,

171
00:09:00,900 --> 00:09:06,700
let's say 'transfer_files.py'. Let me run it and

172
00:09:06,700 --> 00:09:07,700

174
00:09:10,800 --> 00:09:14,000
Done. Go to your remote server. Just list out.

175
00:09:14,000 --> 00:09:18,200
See that. We got a file to this server. That's it.

176
00:09:19,200 --> 00:09:22,000
So guys, this is the simple way to transfer your

177
00:09:22,000 --> 00:09:23,900
file from local server to remote server,

178
00:09:24,200 --> 00:09:27,800
or how to download a file from remote server to local server.

179
00:09:27,800 --> 00:09:31,100
So, the very, very important point here is, whenever if

180
00:09:31,100 --> 00:09:34,700
you are downloading your file,

181
00:09:34,700 --> 00:09:37,200
then remote server file path is the source

182
00:09:37,200 --> 00:09:39,400
and destination is on your local server.

183
00:09:39,400 --> 00:09:41,200
Whenever if you are transferring,

184
00:09:41,200 --> 00:09:45,500
then local server file is the source and remote server path is the destination.

185
00:09:45,500 --> 00:09:48,000
And one more thing, on your remote server

186
00:09:48,000 --> 00:09:51,000
if you don't want to mention complete path for your file,

187
00:09:51,000 --> 00:09:54,000
then before going to download a file from your remote server,

188
00:09:54,000 --> 00:09:58,800
try to point out your 'sftp_client' location to your required path.

189
00:09:58,800 --> 00:10:01,900
Then from there you can download your required file,

190
00:10:01,900 --> 00:10:04,564
so simply, by using 'chdir' operation.

191
00:10:04,555 --> 00:10:05,500
