MacTechGrp Meeting Wednesday Dec 5, 2007 7-9PM
           Room 315 Bldg E51 MIT Sloan School

Next Meeting:

Manage your daemons & logs too!

Mac OS X introduces some elegant improvements to some of the
traditional Unix services. Steve Sisak will give a talk introducing 2
of them: launchd and asl (Apple System Log) and demonstrate some
techniques for debugging daemons and interprocess communication.

In Mac OS X v10.4 Tiger, Apple introduced a new system startup
program called launchd. The launchd daemon takes over many tasks from
cron, xinetd, mach_init, and init, which are UNIX programs that
traditionally have handled system initialization, called systems
scripts, run startup items, and generally prepared the system for the
user.

The Apple System Log facility comprises the asl(3) API, a new syslogd
server, and the syslog(1) command-line utility.  The system supports
structured and extensible messages, permitting advanced message
browsing and management through search APIs and other components of
the Apple system log facility.
