AMQ(8)                  FreeBSD System Manager's Manual                 AMQ(8)

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
     The amq utility provides a simple way of determining the current state of
     the amd(8) program.  Communication is by RPC.  Three modes of operation
     are supported by the current protocol.  By default a list of mount points
     and auto-mounted file systems is output.  An alternative host can be
     specified using the -h option.

     If directory names are given, as output by default, then per file system
     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(8) to use log_file as the log file name.  For security
             reasons, this must be the same log file which amd(8) 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 file systems,
             including the number of references to each file system and any
             error which occurred while mounting.

     -p      Return the process ID of the remote or locally running amd(8).
             Useful when you need to send a signal to the local amd(8)
             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 file systems named in
             directory instead of providing information about them.  Unmounts
             are requested, not forced.  They merely cause the mounted file
             system 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
             subset of the information output by amd(8)'s -v option.

     -w      Translate a full pathname as returned by getcwd(3) into a short
             amd(8) pathname that goes through its mount points.  This option
             requires that amd(8) is running.

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

     -D debug_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(8) 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(8), and need to manage each one
             separately.  If not specified, amq will use the default program
             number for amd(8), 300019.  For security reasons, the only
             alternate program numbers amd(8) can use range from 300019 to
             300029, inclusive.

     -T      Contact amd(8) using the TCP transport only.  Normally amq will
             try TCP, and if that failed, will try UDP.

     -U      Contact amd(8) using UDP (connectionless) transport only.
             Normally amq will try TCP, and if that failed, will try UDP.

CAVEATS
     The amq utility uses a Sun registered RPC program number (300019 decimal)
     which may not be in the rpc(5) database.

     If the TCP wrappers library is available, and the use_tcpwrappers global
     amd.conf(5) option is set to ``yes'', then amd(8) will verify that the
     host running amq is authorized to connect.  The ``amd'' service name must
     be used in the /etc/hosts.allow and /etc/hosts.deny files.  For example,
     to allow only localhost to connect to amd(8), add this line to
     /etc/hosts.allow:

           amd: localhost

     and this line to /etc/hosts.deny:

           amd: ALL
