python paramiko Issue while closing the connection

我的未来我决定 提交于 2019-12-04 19:32:24
I have just been trying ssh connection with paramiko . Everything looks fine, but in the final step, when calling the close() method to disconnect the client. Here is my script: #!/usr/bin/python import paramiko import os ssh = paramiko.SSHClient() private_key = os.path.expanduser('~/.ssh/id_dsa') mkey = paramiko.DSSKey.from_private_key_file(private_key,password='JacquiKoala') ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('monitor', username='probert', pkey = mkey) stdin, stdout, stderr = ssh.exec_command('whoami') print stdout.readlines() ssh.close The shell just hangs

Does paramiko close ssh connection on a non-paramiko exception

心已入冬 提交于 2019-12-04 19:23:16
问题 I'm debugging some code, which is going to result in me constantly logging in / out of some external sftp servers. Does anyone know if paramiko automatically closes a ssh / sftp session on the external server if a non-paramiko exception is raised in the code? I can't find it in the docs and as the connections have to be made fairly early in each iteration I don't want to end up with 20 open connections. 回答1: No, paramiko will not automatically close the ssh / sftp session. It doesn't matter

Do not download empty folders while downloading from SFTP server using Python

I got a code to download files recursively in Python on this site. This code also downloads empty directories on server also. Please help me to modify this code so that it does not download empty directories from the server. Code I have (based on Python pysftp get_r from Linux works fine on Linux but not on Windows ): import os import pysftp from stat import S_IMODE, S_ISDIR, S_ISREG cnopts = pysftp.CnOpts() cnopts.hostkeys = None sftp=pysftp.Connection('192.168.X.X', username='username',password='password',cnopts=cnopts) def get_r_portable(sftp, remotedir, localdir, preserve_mtime=False): for

“ping” isn't allowed to be executed

When I try to use Paramiko to exec any command I get "[COMMAND]" isn't allowed to be executed. But If I do that by using Putty it works fine, any idea what can be causing this? Paramiko: >>>ssh.connect('server',port=22,username='user',password='pass' >>>stdin,stdout,stderr = ssh.exec_command('ping 8.8.8.8 -c 2') >>>output = stdout.readlines() >>>print output [] >>>error = stderr.readlines() >>>print error >>>u'"ping" isn\'t allowed to be executed.\n' Putty: user@server:~$ ping 8.8.8.8 -c 2 PING 8.8.8.8 (8.8.8.8): 56 data bytes 64 bytes from 8.8.8.8: seq=0 ttl=57 time=15.928 ms 64 bytes from 8

Paramiko SSH Tunnel Shutdown Issue

淺唱寂寞╮ 提交于 2019-12-04 13:17:07
问题 I'm working on a python script to query a few remote databases over an established ssh tunnel every so often. I'm fairly familiar with the paramiko library, so that was my choice of route. I'd prefer to keep this in complete python so I can use paramiko to deal with key issues, as well as uses python to start, control, and shutdown the ssh tunnels. There have been a few related questions around here about this topic, but most of them seemed incomplete in answers. My solution below is a hacked

Paramiko equvalent of pipeline controls and input/output pipes

泄露秘密 提交于 2019-12-04 13:04:00
I need a method of paramiko based file transfer with a lightweight SSH2 server ( dropbear ) which has no support for SCP or SFTP . Is there a way of achieving a cat and redirect style file transfer, such as: ssh server "cat remote_file" > local_file with paramiko channels? Can paramiko.Transport.open_channel() or Message() do the job? I am unsure of how to proceed. The following may be useful as a starting point (e.g. ./sshpipe host "command"): #! /usr/bin/env python import sys import paramiko def sshpipe(host, line) : client = paramiko.SSHClient() client.set_missing_host_key_policy(paramiko

DSA key forwarding using Paramiko?

☆樱花仙子☆ 提交于 2019-12-04 12:37:52
I'm using Paramiko to execute bash scripts on a remote server. In some of these scripts, there are ssh connections to other servers. If I use bash only, no Python, my DSA key is forwarded and used by the bash script on the first remote server to connect to the second remote server. When I use Paramiko it's not the case. Bash example: Jean@mydesktop:~ & ssh root@firstserver root@firstserver:~ # ssh root@secondserver hostname secondserver.mydomain.org Using Paramiko: #!/usr/bin/python3 # -*- coding: utf-8 -*- import paramiko class SSHSession: def __init__(self, server_address, user='root', port

pysftp — paramiko SSHException, Bad host key from server

我的未来我决定 提交于 2019-12-04 12:36:56
I'm trying to connect to a remote host via pysftp : try: with pysftp.Connection(inventory[0], username='transit', private_key='~/.ssh/id_rsa.sftp', port=8055) as sftp: sftp.put('/home/me/test.file') except Exception, err: print sys.exc_info() print err However, I get a weird exception raised that I can't find much detail on. (<class 'paramiko.ssh_exception.SSHException'>, SSHException('Bad host key from server',), <traceback object at 0x7fa76269c5a8>) Bad host key from server I found a related question that suggested I run ssh-keygen -R [host] to replace the key in my known_hosts file -- once

Connecting to MySQL database via SSH

问题 I am trying to connect my python program to a remote MySQL Database via SSH. I am using Paramiko for SSH and SQLAlchemy. Here is what I have so far: import paramiko from sqlalchemy import create_engine ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('host', port=port, username='user', password='pass') engine = create_engine('mysql+mysqldb://user:pass@host/db') I am getting an error: sqlalchemy.exc.OperationalError: (_mysql_exceptions

Python Paramiko (Client) Multifactor Authentication

微笑、不失礼 提交于 2019-12-04 09:39:40
I'm attempting to use Paramiko (on Python 2.7) to connect to a host that uses multifactor authentication (username + password + one-time-password). The transport.auth_interactive function seems to be the way to do this (based on what I'm understanding from the documentation), but execution never reaches that point - the authentication fails on the client.connect line. I seem to be missing something. This is the code: #!/usr/bin/env python import paramiko import getpass import os import logging user = "" pw = "" mfa = "" def inter_handler(title, instructions, prompt_list): resp = [] for pr in
