Depending on what firewall software you have installed/available, you should be able to block the outgoing port and depending on how your firewall is setup it should just drop the connection request packet. No connection request, no connection, timeout ensues. This would probably work better if it was implemented at a router level (they tend to drop packets instead of sending resets, or whatever the equivalent is for the situation) but there's bound to be a software package that'd do the trick too.

我经常用来模拟随机连接超时的技术是使用ssh本地端口转发。

ssh -L 12345:realserver.com:80 localhost

这将把localhost:12345上的流量转发到realserver.com:80 如果你想，你也可以在你自己的本地机器上循环这个:

ssh -L 12345:localhost:8080 localhost

因此，您可以将应用程序指向本地主机和自定义端口，并且流量将被路由到目标主机:端口。然后你可以退出这个shell(你可能还需要在退出后ctrl+c shell)，它会杀死转发，导致你的应用程序看到连接丢失。

有很多好的答案，但最干净的解决方案似乎是这项服务

您可以配置超时时间(最多230秒)和最终返回代码。

您可以安装Microsoft Loopback驱动程序，它将为您创建一个单独的接口。然后，您可以在它上连接到您的某些服务(您自己的主机)。然后在网络连接中，你可以禁用/启用这样的接口…

您可以尝试在外部端口(例如200)上连接到一个知名的Web站点。大多数防火墙都在DROP模式下工作，它会为你模拟超时。
