SFTP - 连接被中止（C#）答案

【问题标题】：SFTP - connection was aborted (C#)SFTP - 连接被中止（C#）
【发布时间】：2016-06-20 18:01:09
【问题描述】：

我有从 sftp 下载文件的工具。该工具工作了 2 年，但现在停止工作。收到的错误是：

An established connection was aborted by the software in your host machine.

主机在客户站点上，从主机获取任何日志非常复杂。我想问你可能的原因是什么。

这是来自我的工具的日志：

对于 sftp 连接使用 Renci.SshNet (version 2013.4.7)

【问题讨论】：

您是否尝试过在本地运行代码/调试它..？如果您不显示与实际问题相关的代码，我们怎么能看到发生了什么..？
您可能还包括用于实现 SFTP 的库，因为它在 .Net 中不支持“开箱即用”的东西，除非您自己实现了一些东西。
我的本地测试工作 - 工具停止在客户端工作，这是我的黑匣子。无法连接客户环境。或托管哪个客户使用。我不认为我们可以仅使用此信息找到解决方案。我想知道有一些清单失败的可能性。

【解决方案1】：

问题出在 Renci.SshNet（版本 2013.4.7）中。此版本能够与 SSH-2.0-OpenSSH_6.7 通信，但不能与 SSH-2.0-OpenSSH_7.2 通信。

实际版本的 Renci.SshNet 解决了这个问题。
