NAME

     taskgated -- task_for_pid access control daemon

SYNOPSIS

     taskgated [-ps] [-t timeout] [-i pid]

DESCRIPTION

     taskgated is a system daemon that implements a policy for the task_for_pid system service.  When the kernel is asked for the task port of a
     process, and preliminary access control checks pass, it invokes this daemon (via launchd) to make the decision.

OPTIONS

     -p       Accepts the old (Tiger) convention that a process with a primary effective group of procmod or procview is allowed to get task
	      ports. Without this option, this legacy mode is not supported.

     -s       Allow signed applications marked as "safe" to have free access to task ports, without having to pass an authorization check. Note
	      that such callers must be marked both allowed and safe.

     -t timeout
	      The daemon will quit after that many seconds of inactivity. It will be relaunched by launchd as needed. A timeout of zero can be
	      specified to make the daemon quit after servicing each request, but a small positive timeout is better for performance.

     -i pid   Inject the service port of taskgated into the process with the given pid, rather than relying on launchd to install it system-wide.
	      This is for testing only, and requires the launchd configuration for taskgated to be removed.

AUTHORIZATION RIGHTS

     system.privilege.taskport	Authorization right used to check access of allowed (but not safe) callers.

INFO KEYS

     SecTaskAccess  A value of "allowed" is required for any program that wants access to task ports. A value of "safe" bypasses authorization
		    checks if so configured.  Code must be signed by any system-trusted signing authority.

FILES

     /etc/authorization  to configure the authorization used.
     /System/Library/LaunchDaemons/com.apple.taskgated
			 startup configuration file for taskgated

HISTORY

     taskgated was first introduced in Mac OS 10.5 (Leopard).

     Certain software updates of Mac OS 10.4 (Tiger) introduced the convention requiring membership in the procmod or procview groups to control
     task port access. Before that, any process could obtain the task port of any other process with the same user-id.

NAME

     pcastctl -- Podcast Producer daemons control interface

SYNOPSIS

     pcastctl status target on|off|start|stop|restart

OPTIONS

     The available options are as follows:

     status			    print status of running daemons

     target			    affect agent or server daemon

     start|stop|restart 	    explicitly start/stop/restart daemon.  Note that 'restart' will kill all instances of a given daemon, as will
				    'stop' if none is specified in the pid file.

RETURN VALUES

     0 Completed succesfully.

     1 Action failed

     10 Not run as root.

     50 Target not recognized: use 'a', or 's'.

     51 Action not recognized: use start|stop|restart

     52 Executables not found; may need to reinstall Podcast Producer.

     53 Process directory not found; may need to reinstall Mac OS X.

     54 Timeout waiting for action to complete.

     55 Launchd manipulation failure.

FILES

     /usr/libexec/podcastproducer/pcastagentd
	     Podcast Producer agent daemon

     /usr/share/podcastproducer/pcastserverd
	     Podcast Producer server daemon

     /var/run/pcastagentd.pid
	     Podcast Producer agent process ID

     /var/run/pcastserverd.pid
	     Podcast Producer server process ID

     /System/Library/LaunchDaemons/com.apple.pcastagentd.plist
	     Launchd agent daemon control file

     /System/Library/LaunchDaemons/com.apple.pcastserverd.plist
	     Launchd server daemon control file

EXAMPLES

     status of Podcast Producer agent daemon

	   $ pcastctl agent status

     edit launchd configuration to launch server on system startup

	   $ pcastctl server on

DIAGNOSTICS

     Warning: Warning: ## copies of (pcastagentd|pcastserverd) already running

     Trying to launch another daemon when one or more already running; will usually succeed, but may cause unpredictable behavior.
     See also RETURN VALUES, above.

ERRORS

     Error: failed to launch (executable)

     Tried to start/restart a give daemon, but failed.

     Error: process 'executable' not currently running

     Tried to kill a process which did not exist.

SEE ALSO

HISTORY

     This program was first introduced in Mac OS X 10.5 "Leopard".  It was inspired by xgridctl(8).

BUGS

     pcastctl(8) uses kill -TERM to allow the daemons a chance to die gracefully; there is currently no way to force a kill -KILL.
