我正在尝试从在 Windows 上运行的 Bash 脚本通过 mDNS 连接到 PC。虽然我能够.local在 CMD 中通过其 mDNS 地址 ping PC，但由于主机名解析问题，在 Ubuntu/Bash 窗口中执行相同操作失败。
当我尝试安装时avahi-daemon，似乎无法启动服务，因此我无法解析 mDNS 名称。

我需要做什么才能解析 mDNS 名称？除了安装 Avahi 之外，还有其他方法吗？或者我需要做其他什么才能使此包正常运行？
答案1
您有两个选择：
安装此
libnss-mdns软件包将更改您系统的解析器以.local.通过 mDNS 查询域。请注意，此软件包的大多数版本都不遵守local解析器搜索路径（请参阅这个答案) 因此您需要查找MacbookPro.local而不仅仅是MacbookPro。安装
avahi-utils软件包并使用该avahi-resolve程序进行查找。您可能还会发现此软件包中的其他工具是查找服务等的更简便的方法。
