问题描述
今天我在命令行中使用 ssh 从远程服务器转发端口,使用中间服务器到我的本地机器.
Today I am using ssh in command line to forward ports from a remote server, using an intermediate server to my local machine.
这是我在 shell 中使用的命令:
This is the command I am using in shell:
ssh user@remote_server -L 2443:localhost:433
这个 ssh 会话使用 ssh 配置文件来发出多跳:
This ssh session uses the ssh config file to issue the multi hop:
Host intermediate_server
IdentityFile "google_compute_engine"
Host remote_server
ProxyCommand ssh user@intermediate_server -W %h:%p
ssh 命令需要为中间服务器(使用计算引擎密钥)和远程服务器(不同的密码)输入密码输入密码后,此代码有效:
The ssh command requires entering a password both for the intermediate server (using a compute engine key) and the remote server (different passwords)After entering the passwords, this code works:
import requests
import pandas as pd
from requests.auth import HTTPBasicAuth
url = 'https://localhost:2443/my_site'
my_ds = requests.get(url, auth=HTTPBasicAuth('user', 'password'), verify=False)
print pd.read_json(my_ds.content)
但是,我只能在命令行中使用手动 ssh 隧道使其工作.
However, I could only get it to work using the manual ssh tunnel in the command line.
如何在python中使用密钥、用户名和密码启动双隧道?我尝试使用 sshtunnel 包,但它只能帮助我进行一个端口转发,而不是双端口转发.
How do I initiate a double tunnel with a key, a username and a password in python?I tried to use the sshtunnel package, but it only helps me with one port forwarding and not a double.
推荐答案
你可以试试这个例子:https://github.com/pahaz/sshtunnel#example-4
import sshtunnel
import requests
import pandas as pd
from requests.auth import HTTPBasicAuth
with sshtunnel.open_tunnel(
ssh_address_or_host=('remote_server', 22),
ssh_username="user",
remote_bind_address=('intermediate_server', 22),
block_on_close=False
) as tunnel1:
print('Connection to tunnel1 (intermediate_server) OK...')
with sshtunnel.open_tunnel(
ssh_address_or_host=('127.0.0.1', tunnel1.local_bind_port),
remote_bind_address=('127.0.0.1', 2443),
ssh_username='user',
ssh_password='intermediate_server_pwd',
block_on_close=False
) as tunnel2:
url = 'https://localhost:'+tunnel2.local_bind_port+'/my_site'
my_ds = requests.get(url, auth=HTTPBasicAuth('user', 'password'), verify=False)
print(my_ds.content)
