paramiko

问题 I have been running Hadoop MapReduce jobs by logging into SSH via PuTTy which requires that I enter Host Name/IP address, Login name and password into PuTTY in order to get the SSH command line window. Once in the SSH console window, I then provide the appropriate MR commands, such as: hadoop jar /usr/lib/hadoop-0.20-mapreduce/contrib/streaming/hadoop-streaming-2.0.0-mr1-cdh4.0.1.jar -file /nfs_home/appers/user1/mapper.py -file /nfs_home/appers/user1/reducer.py -mapper '/usr/lib/python_2.7.3

问题 Running on a windows machine python 2.7, whenever I try to run my script using the command line I receive the following error. import winrandom ImportError: DLL load failed: The specified module could not be found. But this error does not happen when I run my script through a python IDE 回答1: Make sure your PATH correctly includes your python2.7 and python2.7\Scripts directories.

问题 I have to write a script that executes some commands on a remote machine using SSH. I had used paramiko for this and everything worked as long as I used IPv4 addressing. I had to switch IPv6 addressing and I can't seem to get Paramiko client to connect. import paramiko s = paramiko.SSHClient() ip6_addr = 'fe80::1112:bcde:789a:1234' s.connect (ip6_addr, username='foo', password='bar') Error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.6/site

问题 I had a working code, which now I am unable to run due to some issues. I am facing the following issues: I am prompted for password, as I run the file using python /path/to/file.py Even if I use fab -l, this file is invoked and I am again prompted for password. Just to let you know, I have a lot of .py (including fabfile.py) files in the directory which are using fabric and other libraries. Here is a snippet of my code: from fabric.api import * env.key_filename = /path/to/my/pem/file def mem

问题 I've followed the steps here http://jessenoller.com/2009/02/05/ssh-programming-with-paramiko-completely-different/ to connect to my server with ssh via Python. I can connect fine and send commands. When I run stderr.readlines(), however, it shows me the error message below every time, even if the command seems to have executed correctly. I've closed the connection and restarted Python, and still the same result. Here's a Python sample: >>> stdin, stdout, stderr = myssh.exec_command("xyz") >>>

问题 I have a code snippet something like this: ssh = paramiko.SSHClient() ssh.load_system_host_keys() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(ip,port=Port, username=usr,password=Psw) stdin, stdout, stderr= ssh.exec_command("watch -n1 ps") print stdout.read(),stderr.read() The problem here is I have to run watch or any infinitely running command for 10 seconds and after that I should send SIGINT (Ctrl + c) and print the status. How do I do that? 回答1: One way to get

问题 I am trying to tail a log file, and it works. But I need to also be able to analyze the output and log for errors and such. I am using the base example on the Paramiko-expect github page and I can not figure out how to do this. import traceback import paramiko from paramikoe import SSHClientInteraction def main(): # Set login credentials and the server prompt hostname = 'server' username = 'username' password = 'xxxxxxxx' port = 22 # Use SSH client to login try: # Create a new SSH client

问题 I installed PyCrypto and Paramiko (in their respective directories) with python3 setup.py install and both were installed successfully. However, when I try import paramiko in the 3.2.5 interpreter, I get this error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Frameworks/Python.framework/Versions/3.2/lib/python3.2/site-packages/paramiko/__init__.py", line 64, in <module> from transport import SecurityOptions, Transport ImportError: No module named

问题 I am writing some functions, using paramiko, to execute commands and create files on a remote host. I would like to write some unit tests for them, but I don't know what would be the simplest way to achieve this? This is what I envisage as being an example outline of my code: import os import paramiko import pytest def my_function(hostname, relpath='.', **kwargs): ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(hostname, **kwargs) sftp = ssh

问题 I want to write a method that takes an IP, username, and password, and returns an open SFTP connection to that server. Here's the code I have, using paramiko : def open_sftp_connection(ip, user, passwd): ssh = SSHClient() ssh.load_system_host_keys() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(ip, 22, user, passwd) assert ssh.get_transport().is_active(), 'Failed to connect to server' sftp = ssh.open_sftp() return sftp If I execute this code directly in a python shell,
