sudo log files

folks;
I just did setup sudo on Solaris 10 through "sudoer" file.
Now, i try to look at the log files to see any user activities under /var/log/syslog & all i see if someone try to run "sudo -u root tcsh" & got an error or was successful. But i don't see any activities, for example:
if a user used: sudo chmod 755 /etc/passwd
and he was successful, i don't see any logs for this activities any where.

Any help?

NAME
mDNSResponder -- Multicast and Unicast DNS daemon SYNOPSIS
mDNSResponder DESCRIPTION
mDNSResponder (also known as 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), mDNSResponder is also the system-wide Unicast DNS Resolver. mDNSResponder 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. mDNSResponder also performs Unicast and Multicast DNS Queries on behalf of client processes, and maintains a cache of the replies. mDNSResponder has no user-specifiable command-line argument, and users should not run mDNSResponder manually. LOGGING
There are several methods with which to examine mDNSResponder's internal state for debugging and diagnostic purposes. The syslog(1) logging levels map as follows: Error - Error messages Warning - Client-initiated operations Notice - Sleep proxy operations Info - Informational messages By default, only log level Error is logged. A SIGUSR1 signal toggles additional logging, with Warning and Notice enabled by default: % sudo killall -USR1 mDNSResponder Once this logging is enabled, users can additionally use syslog(1) to change the log filter for the process. For example, to enable log lev- els Emergency - Debug: % sudo syslog -c mDNSResponder -d A SIGUSR2 signal toggles packet logging: % sudo killall -USR2 mDNSResponder A SIGINFO signal will dump a snapshot summary of the internal state to /var/log/system.log: % sudo killall -INFO mDNSResponder FILES
/usr/sbin/mDNSResponder INFO
For information on Multicast DNS, see http://www.multicastdns.org/ For information on DNS Service Discovery, see http://www.dns-sd.org/ For information on how to use the Multicast DNS and the DNS Service Discovery APIs on Mac OS X and other platforms, see http://developer.apple.com/bonjour/ For the source code to mDNSResponder, see http://developer.apple.com/darwin/projects/bonjour/ BUGS
mDNSResponder bugs are tracked in Apple Radar component "mDNSResponder". HISTORY
The mDNSResponder daemon first appeared in Mac OS X 10.2 (Jaguar). Also available from the Darwin open source repository (though not officially supported by Apple) are mDNSResponder daemons for other plat- forms, including Mac OS 9, Microsoft Windows, Linux, FreeBSD, NetBSD, Solaris, and other POSIX systems.
