Yes, this is possible - you would need to write a VFS module that filters filenames and that substitutes appropriate alternate characters (or just deletes the offending character). It is not possible without writing a VFS module though. Such a module does not exist today. Samba does not write filenames, it simply passes them through to the operating system from the CIFS client. The VFS layer allows interception of system calls. The module would need to intercept the create() system call, procecss the filename, and then pass the filtered name through to the system function call. The bigger question is how this might be implemented. How do you propose to handle the undesirable characters in a manner that is portable across system locales that use multi-byte names. - John T. -- To unsubscribe from this list go to the following URL and read the instructions: https://lists.samba.org/mailman/options/samba

Ehmmm... personally I would not try to fix the name, but return an error...
