SSHClient paramiko Python?

Question

I use this method to send file to remote server:

def runSendArchive(host, port, username, password, remote_directory, archive):
    try:
        s = paramiko.SSHClient()
        s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        s.connect(host, username, password, port)

        sftp = s.open_sftp()
        sftp.put(archive, remote_directory)
        print "3 - The file was uploaded via SSH!"

    except (BadHostKeyException, AuthenticationException, SSHException, socket.error) as e:
        print "4 - Error! The file was not uploaded: ", e

It returns me an exception:

 except (BadHostKeyException, AuthenticationException, SSHException, socket.error) as e: NameError: global name 

'BadHostKeyException' is not defined

How to use this library right?

Now I get the following error:

File "run.py", line 65, in runSendArchive
    sftp.put(archive, remote_directory)
  File "C:\Python27\lib\site-packages\paramiko\sftp_client.py", line 721, in put
    return self.putfo(fl, remotepath, file_size, callback, confirm)
  File "C:\Python27\lib\site-packages\paramiko\sftp_client.py", line 677, in putfo
    with self.file(remotepath, 'wb') as fr:

    t, msg = self._request(CMD_OPEN, filename, imode, attrblock)

  File "C:\Python27\lib\site-packages\paramiko\sftp_client.py", line 859, in _convert_status
    raise IOError(text)
IOError: Failure

65 line is sftp.put(archive, remote_directory)

Judging from the line

paramiko.SSHClient()

you are calling import paramiko

Since BadHostKeyException is in paramiko.ssh_exception , you need to add an

from paramiko.ssh_exception import BadHostKeyException, AuthenticationException, SSHException

See http://docs.paramiko.org/en/2.3/api/ssh_exception.html

• paramiko.ssh_exception.BadHostKeyException
• paramiko.ssh_exception.AuthenticationException
• paramiko.ssh_exception.SSHException

reside in that module.

For your example code snippet you would need to add the following before the runSendArchive function

import socket
import paramiko
from paramiko.ssh_exception import BadHostKeyException, AuthenticationException, SSHException
