NAME AppleVolumes.default, AppleVolumes.system, AppleVolumes - Configuration file used by afpd(8) to determine the shares made available through AFP and specify file name extension mappings. 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 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. 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 appropriate. 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: searchdb 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. tm Enable Time Machine suport for this volume. invisibledots Use with usedots: make dot files invisible. nonetids Try to force ACL unawareness on the client. 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. This should be set for OS X clients. Starting with Netatalk 2.1 it's part of the default config :DEFAULT: line. 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. followsymlinks Follow symlinks on the server. 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 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/", "veto1/veto2/". 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 database backup, this option normally shouldn't be set. nodev always use 0 for device number, helps when the device number is not constant across a reboot, cluster, ... nofileid don't advertise createfileid, resolveid, deleteid calls. nohex Disables :hex translations for anything except dot files. This option makes the '/' character illegal. nostat don't stat volume path when enumerating volumes list, useful for automounting or volumes created by a preexec script. prodos Provides compatibility with Apple II clients. (legacy) FILE NAME EXTENSION MAPPINGS Example. Extension is jpg. Type is "JPEG". Creator is "ogle". .jpg "JPEG" "ogle" Example. Extension is lzh. Type is "LHA ".
