Ubuntu avahi-daemon 找不到“raspberrypi.local”

我使用的是 ubuntu 16.04 LTS 笔记本电脑。我有一台 raspberry pi zero，我将 raspbian 刷入其中。我在 raspberry pi 上启用了 ssh，并将其设置为以太网小工具，以便我可以通过微型 usb 连接 ssh 进入它。我可以从朋友的 macbook ssh 进入 pi，因此 raspberry 软件配置正确。

avahi 守护进程已启动并正在运行：

但是我无法 ping raspberrypi.local 或 raspberry.local。

我不知道 172.18.94.241 地址是什么，但我可以 ping 它但不能 ssh 它，所以我不认为它是 pi。

ifconfig没有显示树莓派连接：

我尝试卸载并重新安装 avahi 守护程序，但没有效果。我做错了什么？

我使用以下方法解决了 Raspberry Pi Zero W 的问题：

网络管理器菜单 -> 编辑连接，编辑新的以太网连接（对我来说是“有线连接 2”）。IPv6 设置 -> 方法 -> 仅本地链接。

网络管理器现在应该能够建立连接。

$ ifconfig
enp0s20f0u1 Link encap:Ethernet  HWaddr 8a:dd:a1:c0:72:c0  
          inet6 addr: fe80::2f6d:7bde:ad10:d2a7/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:165 errors:0 dropped:0 overruns:0 frame:0
          TX packets:493 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:30167 (30.1 KB)  TX bytes:81949 (81.9 KB)

运行以下命令检查 avahi-daemon 是否检测到新设备：

$ avahi-resolve-host-name raspberrypi.local
raspberrypi.local   fe80::c813:143e:4bf0:7607

进而：

$ ssh -6 pi@fe80::c813:143e:4bf0:7607%enp0s20f0u1
Linux raspberrypi 4.9.59+ #1047 Sun Oct 29 11:47:10 GMT 2017 armv6l
...

不幸的是，简单的主机名解析方式不起作用：

$ ssh -6 [email protected]
ssh: Could not resolve hostname raspberrypi.local: Name or service not known
