Is there a simple way to get rid of junk values that come when you SSH using Python's Paramiko library and fetch output from CLI of a remote machine?

I am using Python's Paramiko library to SSH a remote machine and fetch some output from command-line. I see a lot of junk printing along with the actual output. How to get rid of this? chan1.send("ls\n") output = chan1.recv(1024).decode("utf-8") print(output) [u'Last login: Wed Oct 21 18:08:53 2015 from 172.16.200.77\r', u'\x1b[2J\x1b[1;1H[local]cli@BENU>enable', u'[local]cli@BENU#Configure', I want to eliminate, [2J\x1b[1;1H and u from the output. They are junk. It's not a junk. These are ANSI escape codes that are normally interpreted by a terminal client to pretty print the output. If the

Paramiko: calling “cd” command with exec_command does nothing

I have the following program using Paramiko: #!/usr/bin/env python import paramiko hostname = '192.168.1.12' port = 22 username = 'root' password = 'whatl0ol' if __name__ == "__main__": paramiko.util.log_to_file('paramiko.log') ssh = paramiko.SSHClient() ssh.load_system_host_keys() ssh.connect(hostname, port, username, password) while True: pick = raw_input("sshpy: ") stdin, stdout, stderr = ssh.exec_command(pick) print stdout.readlines() But when I connect and try to use cd , it doesn't work. How can I fix this? It looks like you are implementing some kind of interactive program that allows

“OSError: size mismatch in get!” when retrieving files via SFTP using python

由 耗尽温柔 提交于 2019-12-08 13:24:52
问题 I wrote a python script to download files from SFTP server using python using multithreading so that it could connect to multiple servers at a time and download files from them parallelly. It works fine for up to 10 connections but if there are 25 connections then this error shows up suppose there are 5000 files of size 130mb(almost) on each server to be downloaded The code often works successfully on subsequent tries or will run successfully for the first few files in the date range and then

paramiko recv() returning multiple echos of command

I am trying to talk to a WIN10 machine (with OpenSSH installed). For most part it works but when i send a command (via send) and use read channel(via recv), the data i get back has some strange echos for command i sent. Seems like channel has the full command and then it goes to server byte by byte. And all these stages are logged in recv. Below is is a sample code PS: Issue not seen if i talk to a Linux machine isession = paramiko.SSHClient() isession.set_missing_host_key_policy(paramiko.AutoAddPolicy()) isession.connect(ip, username=user, password=pwd) ishell = isession.invoke_shell() ishell

Paramiko Sessions Closes Transport in the Child Process

由 回眸只為那壹抹淺笑 提交于 2019-12-08 13:14:59
问题 We are using paramiko to make a connection library which heavily uses its get_pty or invoke_shell features. Our library uses these channels for interacting with the target device. But whenever we use multiprocessing library, we are not able to use paramiko connection handles in the child process. The transport gets closed in the child process. Is there a way to tell paramiko not to close the connection/channel at fork. This is the sample program for reproducing the problem from paramiko

Output of command executed with paramiko invoke_shell() is paginated (getting “--more--” in recv)

问题 I have a command XYZ sent over a channel using the sendall() channel = ssh.invoke_shell() channel.sendall('XYZ\n') response = channel.recv(2000) I should have the entire output right there, but then I notice that in the last line of the output that I do receive, there is a "--more--" at the end. Like the one that you get when you use the 'less' command. As a result, the channel is still waiting for more output because the buffer is not empty (more output is expected) and the command is

Download files from FTP server: Exception: Error reading SSH protocol banner

问题 I want to download files from an FTP server (I have installed a test vsftpd server on Linux 14.04 lts, Python version 2.7.13, Paramiko version 2.2.1) using the following code (I'm not posting all of it, only where the exception is raised) import datetime import socket import paramiko import os import shutil today = datetime.date.today() - datetime.timedelta(days=3) formattedtime = today.strftime('%Y%m%d') destination = '/home/path/TestDir-%s' % formattedtime if not os.path.exists(destination)

Passing a Paramiko connection SFTPFile as input to a dask.dataframe.read_parquet

由 徘徊边缘 提交于 2019-12-08 08:10:38
问题 I tried to pass class paramiko.sftp_file.SFTPFile instead of file URL for pandas.read_parquet and it worked fine. But when I tried the same with Dask, it threw an error. Below is the code I tried to run and the error I get. How can I make this work? import dask.dataframe as dd import parmiko ssh=paramiko.SSHClient() sftp_client = ssh.open_sftp() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) source_file=sftp_client.open(str(parquet_file),'rb') full_df = dd.read_parquet(source_file

Pass Python variable inside command with Paramiko

问题 With this command, I want to save an output of the smartctl command of the sda drive. Now, since I use RAID, I have multiple drives, not just sda. The following command works fine: stdin, stdout, stderr = ssh.exec_command('/bin/su root -c "smartctl -a /dev/sda > /tmp/smartctl_output1"', get_pty=True) # ORIGINAL I want to achieve that I pass local Python variable "DISK" containing sda, sdb, sdc and so on instead only static value. The following line produces error: stdin, stdout, stderr = ssh

File upload through SFTP (Paramiko) in Python gives IOError: Failure

问题 Aim: I am trying to use SFTP through Paramiko in Python to upload files on server pc. What I've done: To test that functionality, I am using my localhost (127.0.0.1) IP. To achieve that I created the following code with the help of Stack Overflow suggestions. Problem: The moment I run this code and enter the file name, I get the "IOError : Failure", despite handling that error. Here's a snapshot of the error: import paramiko as pk import os userName = "sk" ip = "127.0.0.1" pwd = "1234" client
