NAME

mdnsd - Multicast DNS daemon

SYNOPSIS

mdnsd {-debug}

DESCRIPTION


     mdnsd is the daemon program for Multicast DNS and DNS Service
     Discovery.

     The mdnsd daemon listens on UDP port 5353 for Multicast  DNS
     Query  packets.  When it receives a query for which it knows
     an answer, mDNSResponder issues  the  appropriate  Multicast
     DNS Reply packet.

     The mdnsd daemon also  performs  Multicast  DNS  Queries  on
     behalf  of  client  processes,  and maintains a cache of the
     replies.

     The mdnsd daemon has no user-specifiable command-line  argu-
     ment,  and  users  should  not run mdnsd manually. The mdnsd
     daemon should be managed by the Solaris Management  Facility
     (SMF)  and  should be administered by the svcadm(1M) command
     using the following  fault  management  resource  identifier
     (FMRI):

       svc:/network/dns/multicast:default

     To examine mdnsd internal state, for debugging and diagnostic
     purposes, send it a SIGUSR1 signal, and it will then log a 
     snapshot summary of its internal state using the syslog(3C)
     facility. mdnsd uses the syslog facility code daemon and info
     priority level.

OPTIONS

The mdnsd daemon recognizes the following option:


     -debug  Debug mode. The mdnsd daemon  sends  output  to  the
             standard  error, and does not run in the background.
             This option only intended for debugging the daemon.

CONFIGURATION


     Multicast  DNS can  be used to lookup  hostnames  and  host 
     addresses  by  specifying  mdns  as  a source for hosts and 
     ipnodes  in  the  name  service  switch  configuration file 
     nsswitch.conf(4).  The  configuration  options for hostname 
     and host address queries using Multicast  DNS are stored in
     the SMF repository.  This configuration can be  modified by 
     the   svcccfg(1M)   command   using  the   following  fault 
     management resouce identfier (FMRI):

       svc:/network/mdns:default

     The  configuration  options for  hostname  and host address
     queries using Multicast DNS are stored in a property  group
     named nss_mdns_config.  The  properties  that make  up  the
     configuration options are as follows:

     search		A list of search  domains for  host name 
     			lookup. By default,  no  search  domains 
			are included in the  configuration.  The
			search list is  currently limited to six
			domains.

     valid		A list of valid domains  checked  before
    			Multicast DNS is used to lookup the host 
			name  or  host  address  for  a  domain.  
			Domains specified in the search list are
			always  included  in the valid list. The 
			valid  domain  list is currently limited 
			to ten domains.

     Please  note  the  above configuration options are Volatile 
     and may change in a future release.
