DESCRIPTION

12       This VFS module is part of the samba(7) suite.
13
14       The vfs_full_audit VFS module records selected client operations to the
15       system log using syslog(3).
16
17       vfs_full_audit is able to record the complete set of Samba VFS
18       operations:

125
126       In addition to these operations, vfs_full_audit recognizes the special
127       operation names "all" and "none ", which refer to all the VFS
128       operations and none of the VFS operations respectively.
129
130       If an unknown operation name is used (for example an operation name is
131       miss-spelled), the module will fail to load and clients will be refused
132       connections to a share using this module.
133
134       vfs_full_audit records operations in fixed format consisting of fields
135       separated by '|' characters. The format is:
136
137                     smbd_audit: PREFIX|OPERATION|RESULT|FILE
138
139
140       The record fields are:
141
142              •   PREFIX - the result of the full_audit:prefix string after
143                  variable substitutions
144
145              •   OPERATION - the name of the VFS operation
146
147              •   RESULT - whether the operation succeeded or failed
148
149              •   FILE - the name of the file or directory the operation was
150                  performed on
151
152
153       This module is stackable.
154

OPTIONS

156       full_audit:prefix = STRING
157           Prepend audit messages with STRING. STRING is processed for
158           standard substitution variables listed in smb.conf(5). The default
159           prefix is "%u|%I".
160
161       full_audit:success = LIST
162           LIST is a list of VFS operations that should be recorded if they
163           succeed. Operations are specified using the names listed above.
164           Operations can be unset by prefixing the names with "!". The
165           default is none operations.
166
167       full_audit:failure = LIST
168           LIST is a list of VFS operations that should be recorded if they
169           failed. Operations are specified using the names listed above.
170           Operations can be unset by prefixing the names with "!". The
171           default is none operations.
172
173       full_audit:facility = FACILITY
174           Log messages to the named syslog(3) facility.
175
176       full_audit:priority = PRIORITY
177           Log messages with the named syslog(3) priority.
178
179       full_audit:syslog = true/false
180           Log messages to syslog (default) or as a debug level 1 message.
181
182       full_audit:log_secdesc = true/false
183           Log an sddl form of the security descriptor coming in when a client
184           sets an acl. Defaults to false.
185

EXAMPLES

187       Log file and directory open operations on the [records] share using the
188       LOCAL7 facility and ALERT priority, including the username and IP
189       address. Logging excludes the open VFS function on failures:
190
191                   [records]
192                path = /data/records
193                vfs objects = full_audit
194                full_audit:prefix = %u|%I
195                full_audit:success = open opendir
196                full_audit:failure = all !open
197                full_audit:facility = LOCAL7
198                full_audit:priority = ALERT
