等效于管道控制和输入/输出管道的Paramiko [英] Paramiko equvalent of pipeline controls and input/output pipes

问题描述

我需要一种使用轻量级 SSH2 服务器( dropbear )，它不支持 SFTP .有没有一种方法可以实现猫和重定向样式文件的传输，例如:

I need a method of paramiko based file transfer with a lightweight SSH2 server (dropbear) which has no support for SCP or SFTP. Is there a way of achieving a cat and redirect style file transfer, such as:

ssh server "cat remote_file" > local_file

具有 paramiko 频道吗?

paramiko.Transport.open_channel()或Message()可以完成这项工作吗?我不确定如何进行.

Can paramiko.Transport.open_channel() or Message() do the job? I am unsure of how to proceed.

推荐答案

以下内容可能作为起点(例如./sshpipe主机命令"):

The following may be useful as a starting point (e.g. ./sshpipe host "command"):

#! /usr/bin/env python

import sys
import paramiko

def sshpipe(host, line) :
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(host)
    stdin, stdout, stderr = client.exec_command(line)
    output = stdout.read()
    sys.stdout.write(output)
    stdin.close()
    stdout.close()
    stderr.close()
    client.close()

sshpipe(sys.argv[1], sys.argv[2])
