README for Samba Virtual File System (VFS) Examples
===================================================
This directory contains some sample code to demonstrate VFS
construction. The following VFS modules are given:
skel
A skeleton VFS module. When used, this module simply
passes all requests back to the disk functions (i.e it
operates as a passthrough filter). It should be
useful as a starting point for developing new VFS
modules.
audit
A simple module to audit file access to the syslog
facility. The following operations are logged: share
connect/disconnect, directory opens/create/remove,
file open/close/rename/unlink/chmod.
recycle
A recycle-bin like modules. When used any unlink call
will be intercepted and files moved to the recycle
directory nstead of beeing deleted.
block
A simple module to block access to certain mount points or
directories. This module only hides the specified directories
and all directories beneath them. It should NOT be used to
secure directories. If the name of a file in one of those
directories is known, the file can still be opened.
netatalk
A netatalk module, that will ease co-existence of samba and
netatalk file sharing services.
Looka t the README for more informations.
You may have problems to compile these modules, as shared libraries are
compiled and linked in different ways on different systems.
I currently tested them against GNU/linux and IRIX.
To use the VFS modules, create a share similar to the one below. The
important parameter is the 'vfs object' parameter which must point to
the exact pathname of the shared library object.
[audit]
comment = Audited /data directory
path = /data
vfs object = /path/to/audit.so
writeable = yes
browseable = yes
Further documentation on writing VFS modules for Samba can be found in
docs directory of the Samba source distribution.
