SYNOPSIS

       /etc/netatalk/AppleVolumes.default
                                                                                                                                     /etc/netatalk/AppleVolumes.system
                                                                                                                                     ~/AppleVolumes
                                                                                                                                     ~/.AppleVolumes
                                                                                                                                     ~/applevolumes
                                                                                                                                     ~/.applevolumes

DESCRIPTION

       /etc/netatalk/AppleVolumes.system and one of
       /etc/netatalk/AppleVolumes.default, ~/AppleVolumes, ~/.AppleVolumes,
       ~/applevolumes, or ~/.applevolumes are the configuration files used by
       afpd to determine what portions of the file system will be shared via
       Apple Filing Protocol, as well as their behaviour.

       Any line not prefixed with # is interpreted. Newline escaping is
       supported. The configuration lines are composed like:

       path [ volume name ] [ options ]

       .extension [ type [ creator ] ]

       The path name must be a fully qualified path name, or a path name using
       either the ~ shell shorthand or any of the substitution variables,
       which are listed below.

       The volume name is the name that appears in the Chooser ot the "connect
       to server" dialog on Macintoshes to represent the appropriate share. If
       volumename is unspecified, the last component of pathname is used. No
       two volumes may have the same name. If there are spaces in the name, it
       should be in quotes (i.e. "File Share"). The volume name cannot contain
       the ´:´ character. The volume name is mangled if it is very long. Mac
       codepage volume name is limited to 27 characters. UTF8-MAC volume name
       is limited to -volnamelen parameter in afpd.conf

           Note
           Each volume has to be configured on a single line. Though newline
           escaping is supported.

       The leading-dot lines specify file name extension mappings. The
       extension ´.´ sets the default creator and type for otherwise untyped
       Unix files.

           Note
           File name extension mapping is useful for Mac OS 9 and earlier. But
           it should not use for Mac OS X.

       It is possible to specify default options for all volumes with a
       :DEFAULT: line preceeding these volume definitions:

       Example. :DEFAULT: configuration line

           :DEFAULT: options:upriv,usedots dbpath:/var/dbd/AppleDB/$v dperm:0775 fperm:0664

       The possible options and their meanings are:

       adouble:[v1|v2|osx]
           Specify the format of the metadata files, which are used for saving
           Mac resource fork as well. Earlier versions used AppleDouble V1,
           the new default format is V2. Starting with Netatalk 2.0, the
           scheme MacOS X 10.3.x uses, is also supported.

               Note
               adouble:osx cannot be treated normally any longer. Its only aim
               was to temporarely share eg. FAT32 formatted FireWire
               harddrives written on a Macintosh with afpd. Apple´s metadata
               scheme lacks several essential features, so using it on the
               server´s side will break both CNIDs and MacOS 9 compatibility.
               AppleDouble file of Mac OS X 10.6 is incompatible to V1 and V2.

       volsizelimit:size in MiB
           Useful for TimeMachine: limits the reported volume size, thus
           preventing TM from using the whole real disk space for backup.
           Example: "volsizelimit:1000" would limit the reported disk space to
           1 GB.

       allow:[users/groups]
           The allow option allows the users and groups that access a share to
           be specified. Users and groups are specified, delimited by commas.
           Groups are designated by a @ prefix. Example:
           allow:user1,user2,@group

       deny:[users/groups]
           The deny option specifies users and groups who are not allowed
           access to the share. It follows the same format as the allow
           option.

       allowed_hosts:[IP host address/IP netmask bits[, ... ]]
           Only listed hosts and networks are allowed, all others are
           rejected. The network address may be specified either in
           dotted-decimal format for IPv4 or in hexadecimal format for IPv6.

           Example: allowed_hosts:10.1.0.0/16,10.2.1.100,2001:0db8:1234::/48

       denied_hosts:[IP host address/IP netmask bits[, ...]]
           Listed hosts and nets are rejected, all others are allowed.

           Example: denied_hosts: 192.168.100/24,10.1.1.1,2001:db8::1428:57ab

       cnidscheme:[backend]
           set the CNID backend to be used for the volume, default is [dbd]
           available schemes: [dbd last tdb]

       dbpath:[path]
           Sets the database information to be stored in path. You have to
           specifiy a writable location, even if the volume is read only.

       cnidserver:[fqdn|IP[:port]]
           Query this servername or IP address (default:localhost) and port
           (default: 4700) for CNIDs. Only used with CNID backend "dbd". This
           option here overrides any setting from afpd.conf:cnidserver.

       ea:[none|auto|sys|ad]
           Specify how Extended Attributes are stored.  auto is the default.

           auto
               Try sys (by setting an EA on the shared directory itself),
               fallback to ad. Requires writeable volume for perfoming test.
               options:ro overwrites auto with none. Use explicit ea:sys|ad
               for read-only volumes where appropiate.

           sys
               Use filesystem Extended Attributes.

           ad
               Use files in .AppleDouble directories.

           none
               No Extended Attributes support.

       maccharset:[charset]
           specifies the mac client codepage for this Volume, e.g.
           "MAC_ROMAN", "MAC_CYRILLIC". If not specified the setting from
           afpd.conf is inherited. This setting is only required if you need
           volumes, where the mac codepage differs from the one globally set
           in afpd.conf.

       options:[option]
           This allows multiple options to be specified in a comma delimited
           format. The available options are:

           acls
               Enable ACLs on this volume. Requires a NFSv4 ACLs compatible
               filesystem (e.g. ZFS) and an ACL API compatible to *Solaris. In
               other words: this requires Solaris, Opensolaris or a derived
               distribution.

           tm
               Enable Time Machine suport for this volume.

           invisibledots
               Use with usedots: make dot files invisible.

           limitsize
               Limit disk size reporting to 2GB. This can be used for older
               Macintoshes using newer Appleshare clients.

           preexec_close
               a non-zero return code from preexec close the volume being
               immediately, preventing clients to mount/see the volume in
               question.

           ro
               Specifies the share as being read only for all users. The
               .AppleDB directory has to be writeable, you can use the -dbpath
               option to relocate it. Overwrites ea:auto with ea:none

           root_preexec_close
               a non-zero return code from root_preexec closes the volume
               immediately, preventing clients to mount/see the volume in
               question.

           upriv
               use AFP3 unix privileges. Become familiar with the new "unix
               privileges" AFP permissions concepts in MacOS X before using
               this option. See also: perm|fperm|dperm.

           usedots
               Don´t do :hex translation for dot files. note: when this option
               gets set, certain file names become illegal. These are .Parent
               and anything that starts with .Apple. See also invisibledots.

       password:[password]
           This option allows you to set a volume password, which can be a
           maximum of 8 characters long (using ASCII strongly recommended at
           the time of this writing).

       perm|fperm|dperm:[mode]
           Add(or) with the client requested permissions: perm affects files
           and directories, fperm is for files only, dperm is for directories
           only. Use with options:upriv.

           Example. Volume for a collaborative workgroup

               /path/to/volume "Workgroup" options:upriv dperm:0770 fperm:0660

       umask:[mode]
           set perm mask. Use with options:upriv.

       preexec:[command]
           command to be run when the volume is mounted, ignored for user
           defined volumes

       postexec:[command]
           command to be run when the volume is closed, ignored for user
           defined volumes

       root_preexec:[command]
           command to be run as root when the volume is mounted, ignored for
           user defined volumes

       root_postexec:[command]
           command to be run as root when the volume is closed, ignored for
           user defined volumes

       rolist:[users/groups]
           Allows certain users and groups to have read-only access to a
           share. This follows the allow option format.

       rwlist:[users/groups]
           Allows certain users and groups to have read/write access to a
           share. This follows the allow option format.

       veto:[vetoed name]
           hide files and directories,where the path matches one of the ´/´
           delimited vetoed names. Matches are partial, e.g. path is
           /abc/def/file and veto:/abc/ will hide the file.

       volcharset:[charset]
           specifies the volume codepage, e.g. "UTF8", "UTF8-MAC",
           "ISO-8859-15". Defaults to "UTF8".

VARIABLE SUBSTITUTIONS

       You can use variables in both volume path and volume name.

        1. if you specify an unknown variable, it will not get converted.

        2. if you specify a known variable, but that variable doesn´t have a
           value, it will get ignored.

       The variables which can be used for substitutions are:

       $b
           basename

       $c
           client´s ip or appletalk address

       $d
           volume pathname on server

       $f
           full name (contents of the gecos field in the passwd file)

       $g
           group name

       $h
           hostname

       $i
           client´s ip, without port

       $s
           server name (this can be the hostname)

       $u
           user name (if guest, it is the user that guest is running as)

       $v
           volume name (either ADEID_NAME or basename of path)

       $z
           appletalk zone (may not exist)

       $$
           prints dollar sign ($)

       Example. Using variable substitution when defining volumes

           /home/groups/$g "Groupdir for $g"
           ~ "$f is the best one"

       We define "groupdirs" for each primary group and use a personalized
       server name for homedir shares.

CNID BACKENDS

       The AFP protocol mostly refers to files and directories by ID and not
       by name. Netatalk needs a way to store these ID´s in a persistent way,
       to achieve this several different CNID backends are available. The CNID
       Databases are by default located in the .AppleDB folder in the volume
       root.

       cdb
           "Concurrent database", backend is based on Sleepycat´s Berkely DB.
           With this backend several afpd deamons access the CNID database
           directly. Berkeley DB locking is used to synchronize access, if
           more than one afpd process is active for a volume. The drawback is,
           that the crash of a single afpd process might corrupt the database.

       dbd
           Access to the CNID database is restricted to the cnid_metad daemon
           process.  afpd processes communicate with the daemon for database
           reads and updates. If built with Berkeley DB transactions the
           probability for database corruption is practically zero, but
           performance can be slower than with cdb

       last
           This backend is an exception, in terms of ID persistency. ID´s are
           only valid for the current session. This is basically what afpd did
           in the 1.5 (and 1.6) versions. This backend is still available, as
           it is useful for e.g. sharing cdroms.

           Warning: It is NOT recommended to use this backend for volumes
           anymore, as afpd now relies heavily on a persistent ID database.
           Aliases will likely not work and filename mangling is not
           supported.

       Even though ./configure --help might show that there are other CNID
       backends available, be warned those are likely broken or mainly used
       for testing. Don´t use them unless you know what you´re doing, they may
       be removed without further notice from future versions.

CHARSET OPTIONS

       With OS X Apple introduced the AFP3 protocol. One of the most important
       changes was that AFP3 uses unicode names encoded as UTF-8 decomposed.
       Previous AFP/OS versions used codepages, like MacRoman,
       MacCentralEurope, etc.

       afpd needs a way to preserve extended macintosh characters, or
       characters illegal in unix filenames, when saving files on a unix
       filesystem. Earlier versions used the the so called CAP encoding. An
       extended character (>0x7F) would be converted to a :xx sequence, e.g.
       the Apple Logo (MacRoman: 0XF0) was saved as :f0. Some special
       characters will be converted as to :xx notation as well. ´/´ will be
       encoded to :2f, if -usedots is not specified, a leading dot ´.´ will be
       encoded as :2e.

       This version now uses UTF-8 as the default encoding for names. Special
       characters, like ´/´ and a leading ´.´ will still be CAP style encoded
       .

       The -volcharset option will allow you to select another volume
       encoding. E.g. for western users another useful setting could be
       -volcharset ISO-8859-15.  apfd will accept any iconv(1) provided
       charset. If a character cannot be converted from the mac codepage to
       the selected volcharset, afpd will save it as a CAP encoded character.
       For AFP3 clients, afpd will convert the UTF-8 character to -maccharset
       first. If this conversion fails, you´ll receive a -50 error on the mac.

       Note: Whenever you can, please stick with the default UTF-8 volume
       format.

COMPATIBILITY WITH EARLIER VERSIONS

       To use a volume created with an earlier afpd version, you´ll have to
       specify the following options:

       Example. use a 1.x style volume

           /path/to/volume "Volname" adouble:v1 volcharset:ASCII

       In case you used an NLS you could try using a compatible iconv charset
       for -volcharset.

       Example. use a 1.x style volume, created with maccode.iso8859-1

           /path/to/volume "Volname" adouble:v1 volcharset:ISO-8859-1

       You should consider converting old style volumes to the new UTF-8/AD2
       format. The safest way to do this, is to create a new volume with the
       default options and copy the files between this volumes with a mac.

       Note: Using above example options will allow you to downgrade to 1.x
       netatalk again.

       Note: Some 1.x NLS files used non standard mappings, e.g.
       maccode.iso8859-1.adapted. Three 1.x CAP double-byte maccharsets are
       incompatible to netatalk 2.x; "MAC_CHINESE_TRAD", "MAC_JAPANESE" and
       "MAC_KOREAN". These are not supported anymore. You´ll have to copy the
       contents of those volumes files to a Mac and then back to the netatalk
       server, preferably to an UTF-8 volume.

ADVANCED OPTIONS

       The following options should only be used after serious consideration.
       Be sure you fully understood the, sometimes complex, consequences,
       before using them.

       casefold:[option]
           The casefold option handles, if the case of filenames should be
           changed. The available options are:

           tolower - Lowercases names in both directions.

           toupper - Uppercases names in both directions.

           xlatelower - Client sees lowercase, server sees uppercase.

           xlateupper - Client sees uppercase, server sees lowercase.

       options:[option]
           This allows multiple options to be specified in a comma delimited
           format. The available options are:

           caseinsensitive
               The underlying filesystem is case insensitive (only tested with
               JFS in OS2 mode).

           crlf
               Enables crlf translation for TEXT files, automatically
               converting macintosh line breaks into Unix ones. Use of this
               option might be dangerous since some older programs store
               binary data files as type "TEXT" when saving and switch the
               filetype in a second step.  Afpd will potentially destroy such
               files when "erroneously" changing bytes in order to do line
               break translation.

           dropbox
               Allows a volume to be declared as being a "dropbox." Note that
               netatalk must be compiled with dropkludge support for this to
               function.  Warning: This option is deprecated and might not
               work as expected.

           dropkludge
               same as "dropbox".

           mswindows
               Forces filename restrictions imposed by MS WinXX.  Warning:
               This is NOT recommened for volumes mainly used by Macs. Please
               make sure you fully understand this option before using it.

                   Warning
                   This option breaks direct saving to netatalk volumes from
                   some applications, i.e. OfficeX.

           noadouble
               Forces afpd to not create .AppleDouble directories unless
               macintosh metadata needs to be written. This option is only
               useful if you want to share files mostly used NOT by macs,
               causing afpd to not automatically create .AppleDouble subdirs
               containing AD header files in every directory it enters (which
               will it do by default).

               In case, you save or change files from mac clients, AD metadata
               files have to be written even in case you set this option. So
               you can´t avoid the creation of .AppleDouble directories and
               its contents when you give macs write access to a share and
               they make use of it.

               Try to avoid noadouble whenever possible.

           nocnidcache
               If set afpd doesn´t store the ID information in AppleDouble V2
               header files. As these IDs are used for caching and as a

               not constant across a reboot, cluster, ...
