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 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 filesys
tems 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.
-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 there
fore only useful to refresh amd's open file handle
on the log file, so that it can be rotated and com
pressed 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 run
ning 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.
named in directory instead of providing information
about them. Unmounts are requested, not forced.
They merely cause the mounted filesystem to time
out, which will be picked up by amd's main sched
uler 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'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 regis
tered 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 sepa
rately. If not specified, amq will use the default
program number for amd, 300019. For security rea
sons, 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 deci
mal) which may not be in the /etc/rpc database.
