问题 I want to run a tail -f logfile command on a remote machine using python's paramiko module. I've been attempting it so far in the following fashion: interface = paramiko.SSHClient() #snip the connection setup portion stdin, stdout, stderr = interface.exec_command("tail -f logfile") #snip into threaded loop print stdout.readline() I'd like the command to run as long as necessary, but I have 2 problems: How do I stop this cleanly? I thought of making a Channel and then using the shutdown()

For whatever reason I cannot pass a user input from my original python program over SSH and have it fill in the bash script user input questions. main.py from tkinter import * import SSH hostname = 'xxx' username = 'xxx' password = 'xxx' class Connect: def module(self): name = input() connection = SSH.SSH(hostname, username,

问题 How do you use paramiko to transfer complete directories? I'm trying to use: sftp.put("/Folder1","/Folder2") which is giving me this error - Error : [Errno 21] Is a directory 回答1: You'll need to do this just like you would locally with python (if you weren't using shutils). Combine os.walk() , with sftp.mkdir() and sftp.put() . You may also want to check each file and directory with os.path.islink() depending on whether you want to resolve symlinks or not. 回答2: You can subclass paramiko
