无法通过以太网从Ubuntu ping Beaglebone Black
我刚从盒子里打开了BBB，它的eMMC卡上安装了操作系统。我可以通过串行连接读取控制台输出。我用以太网电缆将我的Ubuntu机器与BBB连接起来。两者位于同一网络，但仍无法ping。BB侧ifconfig的输出无法通过以太网从Ubuntu ping Beaglebone Black,ubuntu,networking,ip,beagleboneblack,Ubuntu,Networking,Ip,Beagleboneblack,我刚从盒子里打开了BBB，它的eMMC卡上安装了操作系统。我可以通过串行连接读取控制台输出。我用以太网电缆将我的Ubuntu机器与BBB连接起来。两者位于同一网络，但仍无法ping。BB侧ifconfig的输出 root@beaglebone:~# ifconfig eth0 Link encap:Ethernet HWaddr 98:84:e3:b8:ad:e3 inet6 addr: fe80::9a84:e3ff:feb8:ade3/64 Scope:L

有人知道为什么无法ping吗？如果您想通过以太网和IPv4与BBB通话，则需要在其连接的LAN上提供DHCPv4服务器或配置静态IPv4地址。仅仅通过直连电缆将BBB连接到Ubuntu机器是行不通的，因为它至少需要在一侧或两侧进行进一步的配置 一种选择是将两台机器连接到具有DHCPv4服务器（在大多数情况下是路由器）的LAN。在您的情况下，只有BBB需要通过以太网连接到它，因为您的PC似乎已经通过WiFi连接到它 注意：IPv6本地链路已成为可能：
- BBB地址：
fe80:：9a84:e3ff:feb8:ade3 - 电脑地址：
fe80:：4d23:a284:24c1:91b5
- 从BBB:
ping6 fe80:：9a84:e3ff:feb8:ade3%eth0 - 从PC:
ping6 fe80:：4d23:a284:24c1:91b5%eno2
