I want to transfer files between two Ubuntu Servers using scp, i have tested scp between the two systems and it worked perfectly fine.So i dont want to execute the command everytime i need to get files so i want to write a python script which automatically downloads files from other host using scp.
While searching online i found this Paramiko module and i have trouble installing this and i have rectified this using module cryptography.Now the real trouble is explained with the terminal below.
>>> from paramiko import SSHClient
>>> from scp import SCPClient
>>> ssh = SSHClient()
>>> ssh
<paramiko.client.SSHClient object at 0x1a41c90>
>>> ssh.load_system_host_keys()
>>> ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
>>> ssh.connect('[email protected]')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/paramiko/client.py", line 296, in c onnect
to_try = list(self._families_and_addresses(hostname, port))

>>> ssh.connect('192.168.100.100')

raise SSHException('Server %r not found in known_hosts' % hostname)
paramiko.ssh_exception.SSHException: Server '192.168.100.100' not found in known_hos ts
I have changed the ip and username for safe use somename is replaced but i have tried with original username.So i tried this several times but i still getting the same error.
Any suggestions on this problem?Please Help.

A Paramiko SSH Example: Connect to Your Server Using a Password. This section shows you how to authenticate to a remote server with a username and password. To begin, create a new file named first_experiment.py and add the contents of the example file. Ensure that you update the file with your own Linode's details.
Paramiko does not itself leverage OpenSSH-style config file directives, but it does implement a parser for the format, which users can honor themselves (and is used by higher-level libraries, such as Fabric).
Answer #1: This is indeed a duplicate of paramiko SSH exec_command(shell script) returns before completion, but the answer there is not terribly detailed. So… As you noticed, exec_command is a non-blocking call.
The python package paramiko was scanned for known vulnerabilities and missing license, and no issues were found. Thus the package was deemed as safe to use.
Maybe you are missing the missing_host_key_policy
What about this one:
proxy = None
client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(host['hostname'], username=host['user'], sock=proxy)

For me the solution was:
client = SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(AutoAddPolicy())
client.connect(host, username=user,password=password)
