NAME
mdnsd - Multicast DNS daemon
SYNOPSIS
mdnsd [-debug]
DESCRIPTION
mdnsd is the daemon program for Multicast DNS and DNS Ser-
vice Discovery.The mdnsd daemon listens on UDP port 5353 for Multicast DNS
Query packets. When it receives a query for which it knowsan answer, mdnsd 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:defaultTo examine mdnsd's internal state for debugging and diagnos-
tic purposes, send it a SIGUSR1 signal, and it will then log a snapshot summary of its internal state using thesyslog(3C) facility. mdnsd uses the syslog facility code
daemon and info priority level. OPTIONSThe mdnsd daemon recognizes the following option:
-debug Debug mode. The mdnsd daemon sends output to the
standard error, and does not run in the back-
ground. This option is only intended for debugging the daemon. CONFIGURATIONSunOS 5.11 Last change: 21 Aug 2007 1

Multicast DNS can be used to look up host names 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 host name and host address queries using Multicast DNS are stored in the SMF repository. This configuration can be modified by the svccfg(1M) command using the following fault management resouce identfier (FMRI): svc:/network/dns/multicast:default The configuration options for host name and host address queries using Multicast DNS are stored in a property groupnamed "nss_mdns_config". The properties that make up the
configuration options are as follows: search A list of search domains for host name look up. By default, no search domains are included in theconfiguration. The search list is currently lim-
ited to six domains. valid A list of valid domains checked before Multicast DNS is used to look up 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. FILES/usr/lib/inet/mdnsd
