       AppleVolumes.default, AppleVolumes.system, AppleVolumes - Configuration file used by
       afpd(8) to determine the shares made available through AFP and specify file name extension




       /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

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

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

           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:

           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.

               adouble:osx cannot be treated normally any longer. Its only aim was to temporarely
               share e.g. 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.  IMPORTANT: This is an approximated calculation taking
           into accout the contents of TM sparsebundle images. Therefor you MUST NOT use this
           volume to store other content when using this option, because it would NOT be
           accounted. The calculation works by reading the band size from the Info.plist XML file
           of the sparsebundle, reading the bands/ directory counting the number of band files,
           and then multiplying one with the other.

           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

           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:,,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,,2001:db8::1428:57ab

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

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

           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

           Specify how Extended Attributes are stored.  auto is the default.

               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 appropriate.

               Use filesystem Extended Attributes.

               Use files in .AppleDouble directories.

               No Extended Attributes support.

           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.

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

               Use fast CNID database namesearch instead of slow recursive filesystem search.
               Relies on a consistent CNID database, i.e. Samba or local filesystem access lead
               to inaccurate or wrong results. Works only for "dbd" CNID db volumes.

               Enable Time Machine suport for this volume.

               Use with usedots: make dot files invisible.

               Try to force ACL unawareness on the client.

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

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

               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

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

               use AFP3 unix privileges. This should be set for OS X clients. Starting with
               Netatalk 2.1 it's part of the default config :DEFAULT: line. See also:

               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.

               Follow symlinks on the server.

           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).

           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

           set perm mask. Use with options:upriv.

       veto:[vetoed names]
           hide files and directories,where the path matches one of the '/' delimited vetoed
           names. The veto string must always be terminated with a '/', e.g. "veto1/",

       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

       The variables which can be used for substitutions are:


           client's ip or appletalk address

           volume pathname on server

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

           group name


           client's ip, without port

           server name (this can be the hostname)

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

           volume name (either ADEID_NAME or basename of path)

           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.


       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.

           "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.

           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

           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.


       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.


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

       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.


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

           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.

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

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

               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.

               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.

               same as "dropbox".

               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.

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

               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

               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.

               If set afpd doesn't store the ID information in AppleDouble V2 header files. As
               these IDs are used for caching and as a database backup, this option normally
               shouldn't be set.

               always use 0 for device number, helps when the device number is not constant
               across a reboot, cluster, ...

               don't advertise createfileid, resolveid, deleteid calls.

               Disables :hex translations for anything except dot files. This option makes the
               '/' character illegal.

               don't stat volume path when enumerating volumes list, useful for automounting or
               volumes created by a preexec script.

               Provides compatibility with Apple II clients. (legacy)
