我一直使用 PuTTY 和 WinSCP SSH 连接到 EC2。我最近Commands > Open in PuTTY在 WinSCP 中发现了该功能，但它似乎不起作用。连接时我收到此错误（PuTTY）：
网络错误：连接被拒绝
这是 PuTTY 事件日志中的错误：

知道为什么连接::1来自 WinSCP 而不是正确的 IP 地址吗？
当我按住Ctrl+Shift并单击时，Open in PuTTY这是剪贴板的内容：
"C:\Program Files\PuTTY\putty.exe" -load aws-ubuntu
aws-ubuntu是 WinSCP 中配置/站点的名称。
答案1
当您在 PuTTY 中存储的会话与 WinSCP 中当前站点的名称匹配时，WinSCP 将指示 PuTTY 使用该会话，而不是将 WinSCP 设置传递给 PuTTY。
看https://winscp.net/eng/docs/integration_putty#session_configuration
你的情况就是这样的（-load aws-ubuntu）。
看来您aws-ubuntu在 PuTTY 中的会话配置与 WinSCP 站点的配置不一样aws-ubuntu。
删除或修复aws-ubuntuPuTTY 中的会话。
