今天,我在命令行中使用ssh从中间服务器到本地计算机的远程服务器转发端口。
这是我在shell中使用的命令:
ssh user@remote_server -L 2443:localhost:433
此ssh会话使用ssh配置文件发出多跳:
Host intermediate_server
IdentityFile "google_compute_engine"
Host remote_server
ProxyCommand ssh user@intermediate_server -W %h:%p
ssh命令需要输入中间服务器(使用计算引擎密钥)和远程服务器(不同的密码)的密码 输入密码后,此代码有效:
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隧道来使其工作。
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软件包,但它仅对一个端口转发有帮助,而对双端口转发没有帮助。
谢谢。

您可以尝试以下示例: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)
