paramiko

问题 I have a problem with connecting to a remote database using SSH tunnel (now I'm trying with Paramiko). Here is my code: #!/usr/bin/env python3 import psycopg2 import paramiko import time #ssh = paramiko.SSHClient() #ssh.load_system_host_keys() #ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) #ssh.connect('pluton.kt.agh.edu.pl', 22, username='aburban', password='pass') t = paramiko.Transport(('pluton.kt.agh.edu.pl', 22)) t.connect(username="aburban", password='pass') c = paramiko

问题 I am in need of python sftp client to download files from a sftp server. I started to use Paramiko. Small files in KB works well but however when I try to download 600 MB of file, it hangs indefinitely after downloading 20 MB of file. Unable to figure out what the issue is. Increasing the window size did not solve either. Any help would be much appreciated! host = config.getsafe(section, "host") username = config.getsafe(section, "username") port = config.getsafe(section, "port") remote_dir =

问题 I intend to run several commands on remote host using paramiko, but the ssh session closed after running a command. The code listed below: from paramiko import SSHClient import paramiko ssh = SSHClient() ssh.load_system_host_keys() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(host, 22, user, passwd, timeout=3) stdin, stdout, stderr = ssh.exec_command('uname -a') So is there any way to stop the ssh session from closing? Or any alternatives for paramiko? Update : I was

问题 I'm desinging test cases in which I use paramiko for SSH connections. Test cases usually contain paramiko.exec_command() calls which I have a wrapper for (called run_command() ). Here self.ssh is an intance of paramiko.SSHClient() . I use a decorator to check the ssh connection before each call. ( self.get_ssh() negotiates the connection) def check_connections(function): ''' A decorator to check SSH connections. ''' def deco(self, *args, **kwargs): if self.ssh is None: self.ssh = self.get_ssh

问题 I am Using Pyhton paramiko and My website server has folder structure like this- 1]dir1 --dirP --dirQ 2]dir2 --dirA --file.sh --dirB 3]dir3 where i want to access file.sh from dirA inside dir2 folder I tried this- import paramiko client.connect('mysite.com', username='something', password='something') stdin, stdout, stderr = client.exec_command('cd dir2') stdin, stdout, stderr = client.exec_command('ls') for line in stdout: print('... ' + line.strip('\n')) but i get output- ...dir1 ...dir2 ..

问题 I have an issue that has been giving me a headache for a few days. I am using the Paramiko module with Python 2.7.10 and I'd like to issue multiple commands to a Brocade router, but only return output from one of the given commands like so: #!/usr/bin/env python import paramiko, time router = 'r1.test.example.com' password = 'password' username = 'testuser' ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(router, username=username, password

问题 I need to be able to upload a file through FTP and SFTP in Python but with some not so usual constraints. File MUST NOT be written in disk. The file how it is generated is by calling an API and writing the response which is in JSON to the file. There are multiple calls to the API. It is not possible to retrieve the whole result in one single call of the API. I can not store in a string variable the full result by doing the multiple calls needed and appending in each call until I have the

问题 This code is not working: def sftp_connection(self): import pysftp connection = pysftp.Connection(self.host, username=self.system_name, private_key=os.path.join(HOME, '.ssh', 'id_rsa')) # in the next lines I try to use AutoAddPolicy client = connection.sftp_client() client.load_host_keys(os.path.expanduser('~/.ssh/known_hosts')) client.set_missing_host_key_policy(paramiko.client.AutoAddPolicy) return connection This is the exception: Traceback (most recent call last): File "/home/u/src/myapp

问题 I wrote a Python script to connect to SFTP server using key authentication. It connects to server successfully but shows the following warning (see below). What does it mean and how to remove it. What changes has to made in code? My code: import os import pysftp import socket import paramiko import time import os.path import shutil IP = "127.0.X.X" myUsername = "USERNAME" port = 22 cnopts = pysftp.CnOpts() cnopts.hostkeys = None import os privatekeyfile = os.path.expanduser("C:\\Users\\Rohan\

问题 I am writing a program in Python which must communicate through SSH with a physical target, and send to this targets some commands automatically (it is for testing). I start by doing this with Paramiko and everything was perfect until I have to send several commands and when for example the second one must be execute in the context of the first (for example the first one makes cd /mytargetRep and the second one is ./executeWhatIWant ). I can't use exec_command to do so, because each exec
