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

131 In addition to these operations, vfs_full_audit recognizes the special
133 operation names "all" and "none ", which refer to all the VFS
134 operations and none of the VFS operations respectively.
135 vfs_full_audit records operations in fixed format consisting of fields
137 separated by '|' characters. The format is:
138 smbd_audit: PREFIX|OPERATION|RESULT|FILE
140 The record fields are:
143 · PREFIX - the result of the full_audit:prefix string after
145 variable substitutions
146 · OPERATION - the name of the VFS operation
148 · RESULT - whether the operation succeeded or failed
150 · FILE - the name of the file or directory the operation was
152 performed on
153 This module is stackable.
156
158 full_audit:prefix = STRING
159 Prepend audit messages with STRING. STRING is processed for
160 standard substitution variables listed in smb.conf(5). The default
161 prefix is "%u|%I".
162 full_audit:success = LIST
164 LIST is a list of VFS operations that should be recorded if they
165 succeed. Operations are specified using the names listed above.
166 Operations can be unset by prefixing the names with "!". The
167 default is none operations.
168 full_audit:failure = LIST
170 LIST is a list of VFS operations that should be recorded if they
171 failed. Operations are specified using the names listed above.
172 Operations can be unset by prefixing the names with "!". The
173 default is none operations.
174 full_audit:facility = FACILITY
176 Log messages to the named syslog(3) facility.
177 full_audit:priority = PRIORITY
179 Log messages with the named syslog(3) priority.
180 full_audit:syslog = true/false
182 Log messages to syslog (default) or as a debug level 1 message.
183 full_audit:log_secdesc = true/false
185 Log an sddl form of the security descriptor coming in when a client
186 sets an acl. Defaults to false.
187
189 Log file and directory open operations on the [records] share using the
190 LOCAL7 facility and ALERT priority, including the username and IP
191 address. Logging excludes the open VFS function on failures:
192 [records]
194 path = /data/records
195 vfs objects = full_audit
196 full_audit:prefix = %u|%I
197 full_audit:success = open opendir
198 full_audit:failure = all !open
199 full_audit:facility = LOCAL7
200 full_audit:priority = ALERT

206 The original Samba software and related utilities were created by
207 Andrew Tridgell. Samba is now developed by the Samba Team as an Open
208 Source project similar to the way the Linux kernel is developed.
