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

RPC
protocol description.
CAVEATS
The
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.conf5
option is set to
``yes
''
then
amd(8)
will verify that the host running
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
