NAME
       radns - Resolving DNS Server Client for IPv6.

SYNOPSIS
       radns [ -v [ -v ] [ -v ]	] [ -f path to resolv file ] [ -l maximum num-
       ber of domain suffixes in search	list ] [ -m maximum number of resolver
       addresses ] [ -u	user ] [ -s path to script ] [ -p path to pidfile ]

DESCRIPTION
       radns  listens  for  IPv6  Router Advertisements	with the Recursive DNS
       Server (RDNSS) option and stores	the address(es)	in a file in the  same
       syntax  as  resolv.conf(5).  It	optionally starts a script when	it re-
       ceives a	Router Advertisement.

OPTIONS
       -V     prints version information and quits the program.

       -v     turns on verbose mode and	gives more debug  output.  Also	 stops
	      the  process  from becoming a daemon. Repeated -v	increases ver-
	      bosity.

       -f path to resolv file
	      specifies	the filename to	write the IPv6 addresses  to.  Default
	      is "./resolv.conf".

       Note  that  the radns user needs	write access to	the directory since it
       will create a temporary working file and	 rename	 it  to	 whatever  you
       specify	 as   the  resolv  file.  Typically  you  use  something  like
       /etc/radns/ra-resolv.conf as the	 resolv	 file  with  /etc/radns	 being
       writable	by the radns user.

       If  radns  is  run on an	IPv6-only machine, with	no dual-stack, you may
       want to make /etc/resolv.conf  a	 symbolic  link	 to  /etc/radns/ra-re-
       solv.conf.

       -l maximum number of domain suffixes in search list specifies
	      the  number of domain suffixes to	store after the	search keyword
	      in the resolv.conf file. 0 is a special case meaning  an	unlim-
	      ited number. The default is 6.

       -m maximum number of resolver addresses
	      specifies	 the  number of	resolver addresses to store in the re-
	      solv.conf	file. 0	is a special case meaning an unlimited number.
	      The default is 3.

       -u username
	      specifies	the user to drop privileges to.	Default	is radns.

       -s path to script
	      specifies	 a program to run after	receiving new addresses	to DNS
	      resolvers. Default is not	to run a script.

       -p path to pidfile
	      specifies	a path to a file to write  the	process	 ID  into  for
	      process management purposes. Default is "/var/run/radns.pid".
