已使用以太网线将装有 Raspian OS 的 Raspberry Pi 2 Model B v1.1 连接到 Ubuntu 20.04 LTS。无法建立 SSH 连接 (ssh[电子邮件保护]）我尝试了一些方法：
- ping 10.42.0.23作品
- 远程控制[电子邮件保护]从树莓派本身工作
- 尝试将我的 ubuntu 的 MTU 从默认的 1500 设置为较小的值（1200、1400）。可以这样做wlp2s0但不是enx00e04c534458（以太网电缆连接）。3.a) iwlist 扫描说接口不支持扫描为了enx00e04c534458也洛。
以下是使用SSH-VVV[电子邮件保护]

答案1
我使用 nm-connection-editor 打开以太网共享连接，手动将 MTU 设置为 1000。现在我可以通过 ssh 进入 raspbian 了。
