vfs_catia - Man Page

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):

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

Resulting filename, as seen by the client:

aÿa÷a¤a¿a¨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​.
