NAME

slaacda stateless address autoconfiguration daemon

SYNOPSIS

slaacd [-dv] [-s socket]

DESCRIPTION

slaacd is a stateless address autoconfiguration (SLAAC) daemon for clients. It listens for IPv6 router advertisement messages, for example those sent by rtadvd(8), on interfaces with the AUTOCONF6 flag set. slaacd derives IPv6 addresses and default routes from received router advertisements and installs them in the kernel. 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
