为什么 avahi-browse 在与静态配置结合使用时不列出我的链接本地地址？

给出以下配置：

auto eth0
allow-hotplug eth0
        iface eth0 inet static
        gateway 192.168.0.1
        address 192.168.0.25
        netmask 255.255.255.0
        post-up /usr/sbin/avahi-autoipd --force-bind --daemonize --wait $IFACE 2> /dev/null
        pre-down /usr/sbin/avahi-autoipd --kill $IFACE 2> /dev/null

我让机器获得一个链路本地地址，同时仍然具有静态配置（当该机器连接到 LAN 时）。问题是，目前，它不会连接到 LAN，我只想使用直接连接两台机器的网线来访问它，并通过给定的链路本地地址进行通信。连接正常，我可以通过 ssh 连接：

我的问题是我还需要让 avahi 发现工作，但可以看出，avahi-browse 没有列出链接本地地址，为什么？如何让它也列出链路本地地址，因为在这种情况下静态配置（192.168.0.25）是没有用的。

答案1

事实是我可以访问静态IP 192.168.0.25！问题是，当我的笔记本电脑连接到 192.168.0.0/24 网络内的 WiFi 时，我尝试使用直接电缆进行通信。关闭 WiFi 后我可以访问 192.168.0.25。
