.SH DESCRIPTION
|
|
.B Amq
|
|
provides a simple way of determining the current state of
|
|
.B amd
|
|
program.
|
|
Communication is by
|
|
.SM 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
|
|
.I \-h
|
|
option.
|
|
.LP
|
|
If
|
|
.I directory
|
|
names are given, as output by default, then per-filesystem
|
|
information is displayed.
|
|
.SH OPTIONS
|
|
|
|
.TP
|
|
.B \-f
|
|
Ask the automounter to flush the internal caches.
|
|
|
|
.TP
|
|
.BI \-h " hostname"
|
|
Specify an alternate host to query. By default the local host is used. In
|
|
an
|
|
.SM HP-UX
|
|
cluster, the root server is queried by default, since that is the system on
|
|
which the automounter is normally run.
|
|
|
|
.TP
|
|
.BI \-l " log_file"
|
|
Tell amd to use
|
|
.I 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.
|
|
|
|
.TP
|
|
.B \-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.
|
|
|
|
.TP
|
|
.B \-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
|
|
.I ctl-amd
|
|
script.
|
|
|
|
.TP
|
|
.B \-s
|
|
Ask the automounter to provide system-wide mount statistics.
|
|
|
|
.TP
|
|
.B \-u
|
|
Ask the automounter to unmount the filesystems named in
|
|
.I directory
|
|
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
|
|
.BR amd 's
|
|
main scheduler thus causing the normal timeout action to be taken.
|
|
|
|
.TP
|
|
.B \-v
|
|
Ask the automounter for its version information. This is a subset of the
|
|
information output by
|
|
.BR amd 's
|
|
.I -v
|
|
option.
|
|
|
|
.TP
|
|
.BI \-x " log_options"
|
|
Ask the automounter to use the logging options specified in
|
|
.I log_options
|
|
from now on.
|
|
|
|
.TP
|
|
.BI \-D " log_options"
|
|
Ask the automounter to use the debugging options specified in
|
|
.I debug_options
|
|
from now on.
|
|
|
|
.TP
|
|
.BI \-M " map_ent"
|
|
Pass a mount map entry to
|
|
.B amd
|
|
and wait for it to be evaluated, possible causing a mount. This option is
|
|
highly insecure. By default, amd and amq do not support it. You have to
|
|
configure am-utils with
|
|
.I \-\-enable\-amq\-mount
|
|
to enable this option.
|
|
|
|
.TP
|
|
.BI \-P " program_number"
|
|
Contact an alternate running amd that had registered itself on a different
|
|
RPC
|
|
.I 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.
|
|
|
|
.TP
|
|
.B \-T
|
|
Contact
|
|
.B amd
|
|
using the TCP transport only. Normally
|
|
.B amq
|
|
will try TCP, and if that failed, will try UDP.
|
|
|
|
.TP
|
|
.B \-U
|
|
Contact
|
|
.B amd
|
|
using UDP (connectionless) transport only. Normally
|
|
.B amq
|
|
will try TCP, and if that failed, will try UDP.
