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

129 In addition to these operations, vfs_full_audit recognizes the special
131 operation names "all" and "none ", which refer to all the VFS
132 operations and none of the VFS operations respectively.
133 vfs_full_audit records operations in fixed format consisting of fields
135 separated by '|' characters. The format is:
136 smbd_audit: PREFIX|OPERATION|RESULT|FILE
138 The record fields are:
141 • PREFIX - the result of the full_audit:prefix string after
143 variable substitutions
144 • OPERATION - the name of the VFS operation
146 • RESULT - whether the operation succeeded or failed
148 • FILE - the name of the file or directory the operation was
150 performed on
151 This module is stackable.
154
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 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 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 full_audit:facility = FACILITY
174 Log messages to the named syslog(3) facility.
175 full_audit:priority = PRIORITY
177 Log messages with the named syslog(3) priority.
178 full_audit:syslog = true/false
180 Log messages to syslog (default) or as a debug level 1 message.
181 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
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 [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

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