我在python的sshtunnel模块中使用SSHTunnelForwarder。
给出下一个代码:
server = SSHTunnelForwarder(
(sshServer, sshPort),
ssh_username=sshUsername,
ssh_password=sshPassword,
remote_bind_address=(imapServer, imapPort),
local_bind_address=('127.0.0.1', localPort)
)
print('STARTING')
server.start()
print(server.is_active)
有时会花费很长时间,也许要花几分钟,然后我会收到错误消息:
2019-04-22 22:25:54,365| ERROR | Could not connect to gateway ip..... : 110
Traceback (most recent call last):
File "PYTHON_TUNNEL.py", line 24, in <module>

sshtunnel.BaseSSHTunnelForwarderError: Could not establish session to SSH gateway
Ubuntu 18.04,Python 2.7
是否可以为建立隧道设置超时时间?
答案 0 :(得分:1)
在SSH_TIMEOUT
上设置了socket used to create the transport常量,并且在{{1}中设置了默认值None
,然后再对其调用sshtunnel.py
。
不幸的是,我自己无法测试,但是您可以在启动隧道转发器之前尝试修补该常量:
connect
还有一个TUNNEL_TIMEOUT
常量,但这似乎用于checks if the tunnel is already established和open_channel
上的underlying Paramiko Transport instance调用。此外,import sshtunnel
sshtunnel.SSH_TIMEOUT = 5.0
server = sshtunnel.SSHTunnelForwarder([...])
server.start()
默认设置为一秒,并且TUNNEL_TIMEOUT
在server.start()
上会经历一分钟的延迟,而在隧道创建过程中似乎没有作用。 BaseSSHTunnelForwarderError
被提出,这个常数似乎不太可能与您的问题的解决方案相关。
