Question

我们正在使用django Web框架构建我们的应用程序。我们在申请中面临着这个非常关键的问题。我们正在尝试使用结构库连接到远程服务器。通常从命令行我们可以连接到服务器。它也可以在内置的服务器中运行，它在django中从命令行运行。命令

fab get_string -H user@10.10.10.10>>django.txt 2>&1

我们在apache中部署了代码，当应用程序在函数中遇到此命令时，应用程序会卡住。偶尔我们得到这些日志

Aborting."

因为它能够终止连接。但在大多数情况下它会卡住，我们没有任何日志可以显示。

然后我们决定将它作为Windows服务运行。我们使用附加的python文件为我们创建服务（recipe.py）。我们再次遇到与我们面对的问题相同的问题。

您可能希望查看您的连接是否因ssh凭据或类似问题而失败。如果您按照my suggestion here并让ssh / paramiko lib详细记录，您可以获得更多信息。
