avahi-daemon 命令

常用示例

说明

avahi-daemon implements Apple's Zeroconf architecture (also known as Rendezvous or Bonjour) on Linux and other Unix-like systems. It registers local IP addresses and static services using mDNS (Multicast DNS) and DNS-SD (DNS Service Discovery) protocols. The daemon provides service discovery functionality, allowing applications and devices on a local network to automatically discover each other without requiring manual configuration or a central DNS server. It publishes services and responds to service discovery queries from other hosts. At startup, avahi-daemon reads its configuration from /etc/avahi/avahi-daemon.conf and loads XML service definitions from **/etc/avahi/services/\*.service. When enabled, it also processes /etc/resolv.conf for unicast DNS server information. The daemon provides two IPC APIs: a simple protocol used by avahi-dnsconfd and nss-mdns, plus a comprehensive D-Bus interface for application integration. Signal handling: SIGINT and SIGTERM trigger shutdown, SIGHUP reloads DNS server data and service definitions, and SIGUSR1** dumps cached resource records to syslog for debugging.
