browsable_dirs " (string, default=no)"

If "yes", then amd's top-level mount points will be browsable to readdir(3) calls.  This means you could run for example ls(3) and see what keys are available to mount in that directory.  Not all entries are made visible to readdir(3) : the "/default" entry, wildcard entries, and those with a "/" in them are not included.  If you specify "full" to this option, all but "/default" will be visible. Note that if you run a command which will attempt to stat(2) the entries, such as often done by "ls -l" or "ls -F", amd will attempt to mount every entry in that map.  This is often called a ``mount storm''.

map_options " (string, default no options)"

This option is the same as specifying map options on the command line to amd, such as "cache:=all".

map_type " (string, default search all map types)"

If specified, amd will initialize the map only for the type given.  This is useful to avoid the default map search type used by amd which takes longer and can have undesired side-effects such as initializing NIS even if not used.  Possible values are

file      plain files
hesiod    Hesiod name service from MIT
ldap      Lightweight Directory Access Protocol
ndbm      (New) dbm style hash files
nis       Network Information Services (version 2)
nisplus   Network Information Services Plus (version 3)
passwd    local password files
union     union maps

mount_type " (string, default=nfs)"

All amd mount types must be NFS.  That is, amd is an NFS server on the map mount points, for the local host it is running on.  If "autofs" is specified, amd will log an error and convert it to NFS.

search_path " (string, default no search path)"

This provides a (colon-delimited) search path for file maps.  Using a search path, sites can allow for local map customizations and overrides, and can distributed maps in several locations as needed.

arch " (string, default to compiled in value)"

Allows you to override the value of the arch amd variable.

auto_dir " (string, default=/a)"

Same as the -a option to amd.  This sets the private directory where amd will create sub-directories for its real mount points.

cache_duration " (numeric, default=300)"

Same as the -c option to amd.  Sets the duration in seconds that looked up map entries remain in the cache.

cluster " (string, default no cluster)"

Same as the -C option to amd.  Specifies the alternate HP-UX cluster to use.

debug_options " (string, default no debug options)"

Same as the -D option to amd.  Specify any debugging options for amd.  Works only if am-utils was configured for debugging using the --enable-debug option.  The "mem" option, as well as all other options, can be turned on via --enable-debug=mem.  Otherwise debugging options are ignored.  Options are comma delimited, and can be preceded by the string "no" to negate their meaning.  You can get the list of supported debugging options by running amd -H.  Possible values are:

all       all options
amq       register for amq
daemon    enter daemon mode
fork      fork server
full      program trace
hrtime    print high resolution time stamps (only if syslog(3) is not used)
info      info service specific debugging (hesiod, nis, etc.)
mem       trace memory allocations
mtab      use local "./mtab" file
readdir   show browsable_dirs progress
str       debug string munging
test      full debug but no daemon
trace     trace protocol and NFS mount arguments
xdrtrace  trace XDR routines

dismount_interval " (numeric, default=120)"

Same as the -w option to amd.  Specify in seconds, the time between attempts to dismount file systems that have exceeded their cached times.

full_os " (string, default to compiled in value)"

The full name of the operating system, along with its version.  Allows you to override the compiled-in full name and version of the operating system. Useful when the compiled-in name is not desired.  For example, the full operating system name on linux comes up as ``linux'', but you can override it to ``linux-2.2.5.''

fully_qualified_hosts " (string, default=no)"

If "yes", Amd will perform RPC authentication using fully-qualified host names.  This is necessary for some systems, and especially when performing cross-domain mounting.  For this function to work, the Amd variable ${hostd} is used, requiring that ${domain} not be null.

hesiod_base " (string, default=automount)"

Specify the base name for hesiod maps.

karch " (string, default to karch of the system)"

Same as the -k option to amd.  Allows you to override the kernel-architecture of your system.  Useful for example on Sun (Sparc) machines, where you can build one amd binary, and run it on multiple machines, yet you want each one to get the correct karch variable set (for example, sun4c, sun4m, sun4u, etc.)  Note that if not specified, amd will use uname(2) to figure out the kernel architecture of the machine.

ldap_base " (string, default not set)"

Specify the base name for LDAP.  This often includes LDAP-specific values such as country and organization.

ldap_cache_maxmem " (numeric, default=131072)"

Specify the maximum memory amd should use to cache LDAP entries.

ldap_cache_seconds " (numeric, default=0)"

Specify the number of seconds to keep entries in the cache.

ldap_hostports " (string, default not set)"

Specify the LDAP host and port values.

local_domain " (string, default no sub-domain)"

Same as the -d option to amd.  Specify the local domain name.  If this option is not given the domain name is determined from the hostname, by removing the first component of the fully-qualified host name.

log_file " (string, default=/dev/stderr)"

Same as the -l option to amd.  Specify a file name to log amd events to. If the string /dev/stderr is specified, amd will send its events to the standard error file descriptor. If the string syslog is given, amd will record its events with the system logger syslogd(8) . The default syslog facility used is LOG_DAEMON.  If you wish to change it, append its name to the log file name, delimited by a single colon.  For example, if logfile is the string syslog:local7 then amd will log messages via syslog(3) using the LOG_LOCAL7 facility (if it exists on the system).

log_options " (string, default no logging options)"

Same as the -x option to amd.  Specify any logging options for amd.  Options are comma delimited, and can be preceded by the string "no" to negate their meaning. The "debug" logging option is only available if am-utils was configured with --enable-debug.  You can get the list of supported debugging and logging options by running amd -H.  Possible values are:

all       all messages
debug     debug messages
error     non-fatal system errors
fatal     fatal errors
info      information
map       map errors
stats     additional statistical information
user      non-fatal user errors
warn      warnings
warning   warnings

nfs_vers " (numeric, default to trying version 3 then 2)"

By default, amd tries version 3 and then version 2.  This option forces the overall NFS protocol used to version 3 or 2.  It overrides what is in the amd maps, and is useful when amd is compiled with NFSv3 support that may not be stable.  With this option you can turn off the complete usage of NFSv3 dynamically (without having to recompile amd) until such time as NFSv3 support is desired again.

nfs_retransmit_counter " (numeric, default=11)"

Same as the retransmit part of the -t timeout.retransmit option to amd. Specifies the number of NFS retransmissions that the kernel will use to communicate with amd.

nfs_retry_interval " (numeric, default=8)"

Same as the timeout part of the -t timeout.retransmit option to amd.  Specifies the NFS timeout interval, in tenths of seconds, between NFS/RPC retries (for UDP only). This is the value that the kernel will use to communicate with amd.
Amd relies on the kernel RPC retransmit mechanism to trigger mount retries. The values of the nfs_retransmit_counter and the nfs_retry_interval parameters change the overall retry interval.  Too long an interval gives poor interactive response; too short an interval causes excessive retries.

nfs_proto " (string, default to trying version tcp then udp)"

By default, amd tries TCP and then UDP.  This option forces the overall NFS protocol used to TCP or UDP.  It overrides what is in the amd maps, and is useful when amd is compiled with NFSv3 support that may not be stable.  With this option you can turn off the complete usage of NFSv3 dynamically (without having to recompile amd) until such time as NFSv3 support is desired again.

nis_domain " (string, default to local NIS domain name)"

Same as the -y option to amd.  Specify an alternative NIS domain from which to fetch the NIS maps.  The default is the system domain name.  This option is ignored if NIS support is not available.

normalize_hostnames " (boolean, default=no)"

Same as the -n option to amd.  If "yes", then the name refereed to by ${rhost} is normalized relative to the host database before being used.  The effect is to translate aliases into ``official'' names.

os " (string, default to compiled in value)"

Same as the -O option to amd.  Allows you to override the compiled-in name of the operating system.  Useful when the built-in name is not desired for backward compatibility reasons.  For example, if the build in name is ``sunos5'', you can override it to ``sos5'', and use older maps which were written with the latter in mind.

osver " (string, default to compiled in value)"

Same as the -o option to amd.  Overrides the compiled-in version number of the operating system.  Useful when the built in version is not desired for backward compatibility reasons.  For example, if the build in version is ``2.5.1'', you can override it to ``5.5.1'', and use older maps that were written with the latter in mind.

pid_file " (string, default=/dev/stdout)"

Specify a file to store the process ID of the running daemon into.  If not specified, amd will print its process id onto the standard output.  Useful for killing amd after it had run.  Note that the PID of a running amd can also be retrieved via amq -p . This file is used only if the print_pid option is on.

plock " (boolean, default=yes)"

Same as the -S option to amd. If "yes", lock the running executable pages of amd into memory.  To improve amd's performance, systems that support the plock(3) call can lock the amd process into memory.  This way there is less chance it the operating system will schedule, page out, and swap the amd process as needed.  This improves amd's performance, at the cost of reserving the memory used by the amd process (making it unavailable for other processes).

portmap_program " (numeric, default=300019)"

Specify an alternate Port-mapper RPC program number, other than the official number.  This is useful when running multiple amd processes.  For example, you can run another amd in "test" mode, without affecting the primary amd process in any way.  For safety reasons, the alternate program numbers that can be specified must be in the range 300019-300029, inclusive. amq has an option -P which can be used to specify an alternate program number of an amd to contact.  In this way, amq can fully control any number of amd processes running on the same host.

print_pid " (boolean, default=no)"

Same as the -p option to amd.  If "yes", amd will print its process ID upon starting.

print_version " (boolean, default=no)"

Same as the -v option to amd, but the version prints and amd continues to run.  If "yes", amd will print its version information string, which includes some configuration and compilation values.

restart_mounts " (boolean, default=no)"

Same as the -r option to amd.  If "yes" amd will scan the mount table to determine which file systems are currently mounted.  Whenever one of these would have been auto-mounted, amd inherits it.

selectors_in_defaults " (boolean, default=no)"

If "yes", then the /defaults entry of maps will search for and process any selectors before setting defaults for all other keys in that map.  Useful when you want to set different options for a complete map based on some parameters.  For example, you may want to better the NFS performance over slow slip-based networks as follows:

/defaults \
    wire==slip-net;opts:=intr,rsize=1024,wsize=1024 \
    wire!=slip-net;opts:=intr,rsize=8192,wsize=8192

Deprecated form: selectors_on_default

show_statfs_entries " (boolean), default=no)"

If "yes", then all maps which are browsable will also show the number of entries (keys) they have when "df" runs. (This is accomplished by returning non-zero values to the statfs(2) system call).

unmount_on_exit " (boolean), default=no)"

If "yes", then amd will attempt to unmount all file systems which it knows about.  Normally amd leaves all (esp. NFS) mounted file systems intact. Note that amd does not know about file systems mounted before it starts up, unless the restart_mounts option or -r flag are used.

vendor " (string, default to compiled in value)"

The name of the vendor of the operating system.  Overrides the compiled-in vendor name.  Useful when the compiled-in name is not desired.  For example, most Intel based systems set the vendor name to ``unknown'', but you can set it to ``redhat.''

map_name " (string, must be specified)"

Name of the map where the keys are located.

tag " (string, default no tag)"

Each map entry in the configuration file can be tagged.  If no tag is specified, that map section will always be processed by amd.  If it is specified, then amd will process the map if the -T option was given to amd, and the value given to that command-line option matches that in the map section.
