pysftp 身份验证超时

如何解决pysftp 身份验证超时

我正在尝试使用 pysftp 自动执行 sftp 传输。目前，我在使用 pysftp 说明书中的代码时遇到身份验证超时错误。这是回溯

Traceback

我也可以使用 sftp -i userid@hostname 登录到服务器，因此端口和凭据应该是正确的。

代码现在正在 VM 上运行，但可以确认相同的代码在我的本地运行。我正在使用 pyhton 3.7 和最新的 pysftp lib

有什么帮助吗？

import sys
import traceback
import pysftp
# get the arguments passed from cmd
hostname = sys.argv[1]
userid = sys.argv[2]
keyFile = sys.argv[3]
logfile = sys.argv[4]
try:
    with pysftp.Connection(hostname,username=userid,private_key = keyFile,log=logfile) as sftp:
        print ('Success')
except Exception:
    traceback.print_exc()

这里是pysftp的日志

我现在在移动设备上没有回溯的文本格式。收到后会再更新

解决方法

看起来是服务器的问题。不知何故，代码在身份验证期间超时。使用 paramiko 的 auth_timeout 参数有效。
