mDNS:mDNS avahi on debian 12

Published

avahi-daemon 是一种Linux操作系统上运行在客户机上实施查找基于网络的Zeroconf service的服务守护进程。 该服务可以为Zeroconf网络实现DNS服务发现及DNS组播规范。 用户程序通过Linux D-Bus信息传递接收发现到网络服务和资源的通知。 该守护进程配合缓存用户程序的答复,以帮助减少因答复而产生的网络流量。

sudo apt-get install avahi-daemon

 

安装 avahi-tools 之后,才能使用 avahi-browse 命令。

可以查看局域网内所有的mdns服务,命令如下:
