NAME
       amq - automounter query tool

SYNOPSIS
       amq [ -fmpsvwHTU ] [ -h hostname ] [ -l log_file ] [ -x log_options ] [
       -D debug_options ] [ -P program_number ] [[ -u ] directory ...  ]

DESCRIPTION
       Amq provides a simple way of determining the current state of amd  pro‐
       gram.  Communication is by RPC.	Three modes of operation are supported
       by the current protocol.	 By default a list of mount points  and	 auto-
       mounted	filesystems  is	 output.  An alternative host can be specified
       using the -h option.

       If directory names are given, as output by default, then per-filesystem
       information is displayed.

OPTIONS
       -f     Ask  the automounter to flush the internal caches and reload all
	      the maps.

       -h hostname
	      Specify an alternate host to query.  By default the  local  host
	      is  used.	  In  an  HP-UX cluster, the root server is queried by
	      default, since that is the system on which  the  automounter  is
	      normally run.

       -l log_file
	      Tell  amd	 to  use  log_file as the log file name.  For security
	      reasons, this must be the same log  file	which  amd  used  when
	      started.	 This option is therefore only useful to refresh amd's
	      open file handle on the log file, so that it can be rotated  and
	      compressed via daily cron jobs.

       -m     Ask  the	automounter  to provide a list of mounted filesystems,
	      including the number of references to each  filesystem  and  any
	      error which occurred while mounting.

       -p     Return  the  process  ID	of  the remote or locally running amd.
	      Useful when you need to send a signal to the local amd  process,
	      and  would  rather not have to search through the process table.
	      This option is used in the ctl-amd script.

       -s     Ask the automounter to provide system-wide mount statistics.

       -u     Ask the automounter to unmount the filesystems named  in	direc‐
	      tory  instead of providing information about them.  Unmounts are
	      requested, not forced.  They merely cause the mounted filesystem
	      to timeout, which will be picked up by amd's main scheduler thus
	      causing the normal timeout action to be taken.

       -v     Ask the automounter for its version information.	This is a sub‐
	      set of the information output by amd's -v option.

       -w     Translate	 a full pathname as returned by getpwd(3) into a short
	      Amd pathname that goes through its mount points.	  This	option
	      requires that Amd is running.

       -x log_options
	      Ask  the	automounter  to	 use  the logging options specified in
	      log_options from now on.

       -D log_options
	      Ask the automounter to use the debugging	options	 specified  in
	      debug_options from now on.

       -H     Display short usage message.

       -P program_number
	      Contact an alternate running amd that had registered itself on a
	      different RPC program_number and apply all other	operations  to
	      that  instance  of the automounter.  This is useful when you run
	      multiple copies of amd, and need to manage each one  separately.
	      If  not  specified,  amq will use the default program number for
	      amd, 300019.  For security reasons, the only  alternate  program
	      numbers amd can use range from 300019 to 300029, inclusive.

       -T     Contact amd using the TCP transport only.	 Normally amq will try
	      TCP, and if that failed, will try UDP.

       -U     Contact amd using UDP (connectionless) transport only.  Normally
	      amq will try TCP, and if that failed, will try UDP.

CAVEATS
       Amq uses a Sun registered RPC program number (300019 decimal) which may
       not be in the /etc/rpc database.

       If the TCP wrappers  library  is	 available,  and  the  use_tcpwrappers
       global amd.conf option is set to ``yes'', then amd will verify that the
       host running amq is authorized to connect.  The amd service  name  must
       used  in	 the /etc/hosts.allow and /etc/hosts.deny files.  For example,
       to  allow  only	localhost  to  connect	to  amd,  add  this  line   to
       /etc/hosts.allow:

	      amd: localhost

       and this line to /etc/hosts.deny:

	      amd: ALL
