使用 Paramiko 进行端口转发 [英] Port forwarding with Paramiko

问题描述

我正在尝试使用 Paramiko 从 Python 应用程序进行一些端口转发.我可以很好地设置 SSH 连接，但我对如何使用 paramiko.Transport 有点困惑.我已经找到 这个文件，但我不知道里面发生了什么.从查看 paramiko.Transport 文档，似乎是使用 open_channel 函数的一行，但我不知道如何实现它.我正在尝试复制一个简单的 ssh -L 8000:localhost:8000.

I'm trying to do some port forwarding from a python app using Paramiko. I can set up the SSH connection just fine, but I'm a bit stumped as to how to use paramiko.Transport. I've already found this file, but I can't work out what's going on in it. From looking at the paramiko.Transport docs, it seems that a single line using the open_channel function, but I can't work out how to implement that. I'm trying to replicate a simple ssh -L 8000:localhost:8000.

有人可以帮我吗?

推荐答案

请使用 paramiko-1.7.7.1、pycrypto-2.6 和 找到一些代码="https://github.com/paramiko/paramiko/blob/master/demos/forward.py" rel="noreferrer">forward.py 脚本，我确实从中删除了第 115 行的代码到结束(以避免选项解析).

Please find some code using paramiko-1.7.7.1, pycrypto-2.6 and the forward.py script from which I did remove code from the line 115 to the end (to avoid options parsing).

import paramiko, sys
from forward import forward_tunnel

remote_host = "target_host"
remote_port = 8000
local_port  = 8000
ssh_host    = "my_ssh_host"
ssh_port    = 22

user     = "login"
password = "s3cr3t"

transport = paramiko.Transport((ssh_host, ssh_port))

# Command for paramiko-1.7.7.1
transport.connect(hostkey  = None,
                  username = user,
                  password = password,
                  pkey     = None)

try:
    forward_tunnel(local_port, remote_host, remote_port, transport)
except KeyboardInterrupt:
    print 'Port forwarding stopped.'
    sys.exit(0)

我已经在 Windows 工作站上成功测试了它，使用 Red Hat 下的 ssh 服务器并指向第三台服务器.(我使用的是 Python 2.7.2)

I've tested it successfully from a Windows station, using a ssh server under Red Hat and pointing to a 3rd server. (I'm using Python 2.7.2)
