+.Sh SYNOPSIS
+.Nm
+.\"
+.Sh DESCRIPTION
+.Nm
+(also known as
+.Nm mdnsd
+on some systems)
+is a daemon invoked at boot time to implement Multicast DNS and DNS Service Discovery. On
+Mac OS X 10.6 (Snow Leopard), 
+.Nm 
+is also the system-wide Unicast DNS Resolver.
+.Pp
+.Nm
+listens on UDP port 5353 for Multicast DNS Query packets.
+When it receives a query for which it knows an answer,
+.Nm
+issues the appropriate Multicast DNS Reply packet.
+.Pp
+.Nm
+also performs Unicast and Multicast DNS Queries on behalf of client processes, and 
+maintains a cache of the replies.
+.Pp
+.Nm
+has no user-specifiable command-line argument, and users should not run
+.Nm
+manually.
+.Pp
+.Ss LOGGING
+There are several methods with which to examine 
+.Nm Ns 's internal state for debugging and diagnostic purposes. The syslog(1)
+logging levels map as follows:
+.Pp
+.Dl Error - Error messages
+.Dl Warning - Client-initiated operations
+.Dl Notice - Sleep proxy operations
+.Dl Info - Informational messages
+.Pp
+By default, only log level Error is logged.
+.Pp
+A SIGUSR1 signal toggles additional logging, with Warning and Notice
+enabled by default:
+.Pp
+.Dl % sudo killall -USR1 mDNSResponder
+.Pp
+Once this logging is enabled, users can additionally use syslog(1)
+to change the log filter for the process. For example, to enable log levels Emergency - Debug:
+.Pp
+.Dl % sudo syslog -c mDNSResponder -d
+.Pp
+A SIGUSR2 signal toggles packet logging:
+.Pp
+.Dl % sudo killall -USR2 mDNSResponder
+.Pp
+A SIGINFO signal will dump a snapshot summary of the internal state to 
+.Pa /var/log/system.log Ns :
+.Pp
+.Dl % sudo killall -INFO mDNSResponder

+daemons for other platforms, including Mac OS 9, Microsoft Windows,
+Linux, FreeBSD, NetBSD, Solaris, and other POSIX systems.
