每当我通过代理访问几个站点后，使用 ssh 命令在 Linux 上打开 SSH 隧道时，我都会收到此信息：channel_by_id：3：坏 id：通道可用断开连接：收到不存在的通道 3 的 ieof。
在 Windows 上，我使用的隧道软件只处理通道关闭并在必要时打开新的通道。有没有客户端或方法可以在 Linux 上执行此操作？我找到了一个名为 autossh 的程序，但每次重新连接时我都需要重新输入密码，因为它会重置整个连接而不仅仅是通道。
这是使用 -v 的 ssh 的输出

答案1
事实证明，我使用的服务器违反了 SSH 协议，只需更改服务器软件就可以修复它。

答案2
当我在 Windows 10 上打开开发人员模式时，我遇到了这个问题，它启动了 Windows 原生 SSH 服务器，而不是预期的 OpenSSH 服务器。通常，请检查您尝试登录的 ssh 守护程序。
