SLAACD(8) FreeBSD System Manager's Manual SLAACD(8)
NAME
slaacd - Stateless Address Autoconfiguration (SLAAC) daemon
SYNOPSIS
slaacd [-dv] [-s socket]
DESCRIPTION
slaacd is a stateless address autoconfiguration (SLAAC) daemon for
clients. If an interface has the AUTOCONF6 flag set (auto configuration
is enabled), slaacd regularly sends out requests for IPv6 router
advertisement messages, such as those sent by rad(8), and uses those
messages to configure the relevant interface.
See hostname.if(5) and ifconfig(8) on how to enable auto configuration on
an interface.
slaacd monitors network interface states (interface going up or down,
auto configuration enabled or disabled, etc.) and sends router
solicitations when necessary. A running slaacd can be controlled with
the slaacctl(8) utility.
The options are as follows:
-d Do not daemonize. If this option is specified, slaacd will run
in the foreground and log to stderr.
-s socket
Use an alternate location for the default control socket.
-v Produce more verbose output. Multiple -v options increase the
verbosity.
FILES
/dev/slaacd.sock UNIX-domain socket used for communication with
slaacctl(8).
