local-unbound(8)	      local-unbound 1.8.1	      local-unbound(8)

NAME
       unbound - Local-unbound DNS validating resolver 1.8.1.

SYNOPSIS
       unbound [-h] [-d] [-p] [-v] [-c cfgfile]

DESCRIPTION
       Unbound is a caching DNS	resolver.

       It  uses	a built	in list	of authoritative nameservers for the root zone
       (.), the	so called root hints.  On receiving a DNS query	 it  will  ask
       the root	nameservers for	an answer and will in almost all cases receive
       a delegation to a top level domain (TLD)	authoritative nameserver.   It
       will  then ask that nameserver for an answer.  It will recursively con-
       tinue until an answer is	found or no answer  is	available  (NXDOMAIN).
       For performance and efficiency reasons that answer is cached for	a cer-
       tain time (the answer's time-to-live or TTL).  A	second query  for  the
       same name will then be answered from the	cache.	Local-unbound can also
       do DNSSEC validation.

       To use a	locally	running	Unbound	for resolving put

	     nameserver	127.0.0.1

       into resolv.conf(5).

       If authoritative	DNS is needed as well using nsd(8), careful  setup  is
       required	 because authoritative nameservers and resolvers are using the
       same port number	(53).

       The available options are:

       -h     Show the version and commandline option help.

       -c cfgfile
	      Set the config file with	settings  for  local-unbound  to  read
	      instead	of   reading   the   file  at  the  default  location,
	      /var/unbound/unbound.conf.   The	 syntax	  is   described    in
	      unbound.conf(5).

       -d     Debug  flag:  do not fork	into the background, but stay attached
	      to the console.  This flag will also delay writing  to  the  log
	      file  until the thread-spawn time, so that most config and setup
	      errors appear on stderr. If given	twice or  more,	 logging  does
	      not  switch  to  the log file or to syslog, but the log messages
	      are printed to stderr all	the time.

       -p     Don't use	a pidfile.  This  argument  should  only  be  used  by
	      supervision  systems  which can ensure that only one instance of
	      local-unbound will run concurrently.

       -v     Increase verbosity. If given multiple times, more	information is
	      logged.	This is	in addition to the verbosity (if any) from the
	      config file.

       tion.
