avahi-autoipd 命令

常用示例

说明

avahi-autoipd implements IPv4LL (_Dynamic Configuration of IPv4 Link-Local Addresses_), a protocol defined in IETF RFC3927 for automatic IP address configuration from the link-local 169.254.0.0/16 range without requiring a central server. Primarily intended for ad-hoc networks which lack a DHCP server, it serves as a core component of the Zeroconf stack. The daemon can operate standalone or integrate with DHCP clients as a fallback mechanism when DHCP is unavailable. When started, avahi-autoipd probes the network for address conflicts, acquires an available link-local address, and continuously monitors for conflicts. Upon successful acquisition, it executes /etc/avahi/avahi-autoipd.action script to configure the network interface. The daemon responds to signals: SIGINT and SIGTERM trigger shutdown, while SIGHUP forces re-announcement of the current IP address.

-S, --start=_address_

Acquire the specified IPv4LL address

-w, --wait
