.PP

:ETCDIR:/AppleVolumes\&.system
and one of
:ETCDIR:/AppleVolumes\&.default,
~/AppleVolumes,
~/\&.AppleVolumes,
~/applevolumes, or
~/\&.applevolumes
are the configuration files used by
\fBafpd\fR
to determine what portions of the file system will be shared via Apple Filing Protocol, as well as their behaviour\&.
.PP
Any line not prefixed with # is interpreted\&. Newline escaping is supported\&. The configuration lines are composed like:
.PP
path
\fI[ volume name ] [ options ]\fR
.PP
\&.extension
\fI[ type [ creator ] ]\fR
.PP
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\&.
.PP
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

.SH "CNID BACKENDS"
.PP
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\&.
.PP
cdb
.RS 4
"Concurrent database", backend is based on Sleepycat\'s Berkely DB\&. With this backend several
\fBafpd\fR
deamons access the CNID database directly\&. Berkeley DB locking is used to synchronize access, if more than one
\fBafpd\fR
process is active for a volume\&. The drawback is, that the crash of a single
\fBafpd\fR
process might corrupt the database\&.
.RE
.PP
dbd
.RS 4
Access to the CNID database is restricted to the
\fBcnid_metad\fR
daemon process\&.
\fBafpd\fR
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
\fBcdb\fR
.RE
.PP
last
.RS 4
This backend is an exception, in terms of ID persistency\&. ID\'s are only valid for the current session\&. This is basically what
\fBafpd\fR
did in the 1\&.5 (and 1\&.6) versions\&. This backend is still available, as it is useful for e\&.g\&. sharing cdroms\&.
.sp
\fBWarning\fR: It is
\fINOT\fR
recommended to use this backend for volumes anymore, as
\fBafpd\fR
now relies heavily on a persistent ID database\&. Aliases will likely not work and filename mangling is not supported\&.
.RE
.PP
Even though
\fB\&./configure \-\-help\fR
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\&.
.SH "CHARSET OPTIONS"
.PP
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\&.
.PP
\fBafpd\fR
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
\fB\-usedots\fR
is not specified, a leading dot \'\&.\' will be encoded as
:2e\&.
.PP
This version now uses UTF\-8 as the default encoding for names\&. Special characters, like \'/\' and a leading \'\&.\' will still be CAP style encoded \&.
.PP
The
\fB\-volcharset\fR
option will allow you to select another volume encoding\&. E\&.g\&. for western users another useful setting could be \-volcharset ISO\-8859\-15\&.
\fBapfd\fR
will accept any
\fBiconv\fR(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,
\fBafpd\fR
will convert the UTF\-8
character to
\fB\-maccharset\fR
first\&. If this conversion fails, you\'ll receive a \-50 error on the mac\&.
.PP
\fINote\fR: Whenever you can, please stick with the default UTF\-8 volume format\&.
.SH "COMPATIBILITY WITH EARLIER VERSIONS"
.PP
To use a volume created with an earlier
\fBafpd\fR
version, you\'ll have to specify the following options:
.PP
\fBExample.\ \&use a 1.x style volume\fR
.sp
.if n \{\
.RS 4
.\}
.nf
/path/to/volume "Volname" adouble:v1 volcharset:ASCII
.fi
.if n \{\
.RE
.\}
.PP
In case you used an NLS you could try using a compatible iconv charset for
\fB\-volcharset\fR\&.
.PP
\fBExample.\ \&use a 1.x style volume, created with maccode.iso8859-1\fR
.sp
.if n \{\
.RS 4
.\}
.nf
/path/to/volume "Volname" adouble:v1 volcharset:ISO\-8859\-1
.fi
.if n \{\
.RE
.\}
.PP
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\&.
.PP
\fINote\fR: Using above example options will allow you to downgrade to 1\&.x netatalk again\&.
.PP
\fINote\fR: 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\&.
.SH "ADVANCED OPTIONS"

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

.RE
.PP
crlf
.RS 4
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\&.
