NAME

       vfs_catia - translate illegal characters in Catia filenames

SYNOPSIS

       vfs objects = catia

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       The Catia CAD package commonly creates filenames that use characters that are illegal in CIFS filenames. The vfs_catia VFS module
       implements a character mapping so that these files can be shared with CIFS clients.

       This module is stackable.

       The parameter "catia:mappings" specifies the mapping on a per-character basis, see below.

OPTIONS

       catia:mappings = SERVER_HEX_CHAR:CLIENT_HEX_CHAR
	   SERVER_HEX_CHAR specifies a 0x prefixed hexedecimal character code that, when included in a Samba server-side filename, will be mapped
	   to CLIENT_HEX_CHAR for the CIFS client.

	   The same mapping occurs in the opposite direction. Multiple character mappings are separated by a comma.

EXAMPLES

       Map server-side quotation-marks (") to client-side diaeresis (") on filenames in the [CAD] share:

		   [CAD]
		path = /data/cad
		vfs objects = catia
		catia:mappings = 0x22:0xa8

       Perform comprehensive mapping of common Catia filename characters:

		   [CAD]
		path = /data/cad
		vfs objects = catia
		catia:mappings = 0x22:0xa8,0x2a:0xa4,0x2f:0xf8,0x3a:0xf7,0x3c:0xab,0x3e:0xbb,0x3f:0xbf,0x5c:0xff,0x7c:0xa6

       Server-side filename to be translated (Note that the path delimiter "/" is not used here):

       aa:a*a?a"a<a>a|a

       Resulting filename, as seen by the client:

       aya-:-axaca"a<<a>>a|a

CAVEATS

       Character mapping must work in BOTH directions (server -> client and client -> server) to get unique and existing file names!

       A NOT working example:

		   [CAD]
		path = /data/cad
		vfs objects = catia
		catia:mappings = 0x3a:0x5f

       Here the colon ":" is mapped to the underscore "_".

       Assuming a server-side filename "a:should_work", which is translated to "a_should_work" for the client.

       BUT the reverse mapping from client "a_should_work" to server will result in "a:should:work" - something like "file not found" will be
       returned.

NAME

       vfs_readahead - pre-load the kernel buffer cache

SYNOPSIS

       vfs objects = readahead

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       This vfs_readahead VFS module detects read requests at multiples of a given offset (hex 0x80000 by default) and then tells the kernel via
       either the readahead system call (on Linux) or the posix_fadvise system call to pre-fetch this data into the buffer cache.

       This module is useful for Windows Vista clients reading data using the Windows Explorer program, which asynchronously does multiple file
       read requests at offset boundaries of 0x80000 bytes.

       The offset multiple used is given by the readahead:offset option, which defaults to 0x80000.

       The size of the disk read operations performed by vfs_readahead is determined by the readahead:length option. By default this is set to the
       same value as the readahead:offset option and if not set explicitly will use the current value of readahead:offset.

       This module is stackable.

OPTIONS

       readahead:offset = BYTES
	   The offset multiple that causes readahead to be requested of the kernel buffer cache.

       readahead:length = BYTES
	   The number of bytes requested to be read into the kernel buffer cache on each readahead call.

       The following suffixes may be applied to BYTES:

       o   K - BYTES is a number of kilobytes

       o   M - BYTES is a number of megabytes

       o   G - BYTES is a number of gigabytes

EXAMPLES

		[hypothetical]
		vfs objects = readahead

       This man page is correct for version 3.0.25 of the Samba suite.
