autofsd(1M)							   autofsd(1M)

NAME    [Toc]    [Back]

     autofsd - autoFS mount/unmount daemon

SYNOPSIS    [Toc]    [Back]

     autofsd [ -vT ] [ -p priority ] [ -tp duration ] [	-D name=value ]
	     [-m maxthreads ]  [-E user	] [ -P tcp|udp ]

DESCRIPTION    [Toc]    [Back]

     autofsd is	an RPC server that answers filesystem mount and	unmount
     requests from the AutoFS filesystem.  It uses local files or name service
     maps to locate filesystems	to be mounted.	These maps are described with
     the autofs(1M) command.

     The autofsd daemon	is started during system initialization	from the
     /etc/init.d/network script	if the configuration flags nfs and autofs are
     set on.  Type the following commands as superuser to enable AutoFS:

	  /etc/chkconfig nfs on
	  /etc/chkconfig autofs	on

     Rebooting invokes the autofs command and start the	autofsd	daemon with
     the options contained in the file /etc/config/autofs.options.  The	autofs
     command passes mount point	configuration information found	in the file
     /etc/auto_master to autofsd.  Do not kill autofsd to change the AutoFS
     configuration.  Run the autofs command to cause changes in	the
     configuration maps	to take	affect.

OPTIONS    [Toc]    [Back]

     -v		     Verbose.  Log status messages to the console.

     -T		     Trace.  Expand each RPC call and display it on the
		     standard output.

     -p	priority     Set the priority of the daemon process.  The daemon will
		     run at the	priority specified, with a scheduling policy
		     of	SCHED_TS. The default priority is 30.

     -tp duration    Specify the duration, in seconds, that the	results	of a
		     probe of a	server's availability will remain cached.  The
		     default is	5 seconds.

     -D	name=value   Assign value to the indicated AutoFS map substitution
		     variable.	These assignments cannot be used to substitute
		     variables in the master map, auto_master.

     -m	maxthreads   Set the maximum number of threads that autofsd will
		     create to handle autofs mount or unmount requests.
		     autofsd will create the threads only when needed. At this
		     time the user cannot specify a number greater than	16 for
		     maxthreads. The default is	to run autofsd multi-threaded
		     with the maximum, 16 threads. Setting this	option to the
		     value 1 will cause	autofsd	to run as a single threaded

     -E	user	     autofsd will first	do a setuid to the specified user
		     before executing any autofs maps. This is done for
		     security reasons, to allow	the system administrator to
		     specify that autofsd should execute autofs	maps, if any,
		     as	a user who does	not have any superuser privileges.

     -P	tcp|udp	     autofsd will default to do	all nfs	mounts with the	IP
		     protocol specified	here. The user can override the
		     protocol specified	here by	using the proto=xyz mount
		     option in the autofs maps.	The currently allowed options
		     are only tcp and udp. If this (-P)	option is not used,
		     the default is to do all nfs mounts with udp. If the tcp
		     option is specified and the remote	nfs server does	not
		     support nfs over tcp, autofsd will	retry the mount	over

FILES    [Toc]    [Back]

     /etc/auto_master		  master map for AutoFS
     /etc/config/autofs.options	  options and arguments	for the	autofs command
				  and the autofsd daemon

SEE ALSO    [Toc]    [Back]

     autofs(1M), chkconfig(1M),	mount(1M), sched_setscheduler(2).

CAVEATS    [Toc]    [Back]

     For security reasons, the user should be extremely	wary using the -E
     option. It's use is deprecated. Support for executable autofs maps	may go
     away in the future.
