在Python中尝试使用sshtunnel

Question

我有一个shell脚本，我想用python脚本替换它。脚本正在初始化SSH隧道以公开TCP流。。。 我想用python做同样的事情，但是我总是有一个错误。你知道吗

shell中的命令行如下所示：

ssh -l monlogin -i /home/toto/.ssh/test/id_dsa -L 10205:127.0.0.1:10205  IP

在这个命令之后，我可以在10205上执行telnet并查看数据流。你知道吗

在python中：

import time
from sshtunnel import open_tunnel
import socket

if __name__ == '__main__':

    with open_tunnel(
    ('IP', 22),
    ssh_username="monlogin",
    ssh_pkey='/home/toto/.ssh/test/id_dsa',
    ssh_private_key_password=None,
    remote_bind_address=('127.0.0.1', 10205),
    local_bind_address=('127.0.0.1', 10205),
    debug_level=10,
    #threaded=False,
    ) as server:
        time.sleep(10)
        print(server.local_bind_port)
        while True:
            # # Create a TCP/IP socket
            # sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            # # Connect the socket to the port where the server is listening
            # server_address = ('127.0.0.1', 10205)
            # sock.connect(server_address)
            # #sock.settimeout(0)
            # while True:
            #     data = sock.recv(4096).decode('ascii')
            #     if data:
            #         print(data)
            #     time.sleep(0.01)
            time.sleep(1)

    print('FINISH!')

我可以执行它，它将打印local_bind_port，但是，当我执行“telnet localhost 10205”时，我有以下错误：

我无法访问远程服务器。但有点不对劲。你知道吗？你知道吗
