# vfs\_catia(8)

translate illegal characters in Catia filenames

## NAME

vfs\_catia - translate illegal characters in Catia filenames

## SYNOPSIS

vfs objects = catia

## DESCRIPTION

This VFS module is part of the [**samba**(7)](/samba/7.md) 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÷aa¿a¨a«a»aa

## 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.
