Question

我用Banana Pro板的yocto项目构建了一个图像。我试图通过ssh root@10.1.80.x连接端口，但我不能。

Ssh始终挂在Entering interactive session阶段。当我运行ssh -v参数时，我捕获了以下日志：

我试图更改MTU，但它没有用。

我该如何解决这个问题？

Answer 1

问题纯粹是偶然解决的。我不知道为什么。

通常情况下，我在连接以太网电缆启动后手动运行modprobe sunxi-gmac和/etc/init.d/networking restart命令。但是这次，不小心，我忘了事先插上电缆，但在/etc/init.d/networking restart命令运行期间插入（发送发现阶段）。令我惊讶的是，ssh连接已经实现！这种行为是确定性的（足够尝试）。

任何人都可以解释这种奇怪的情况吗？为什么我应该在网络重启期间插入以太网电缆而不是之前？

SSH挂起“进入交互式会话”阶段
