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

130 In addition to these operations, vfs_full_audit recognizes the special
132 operation names "all" and "none ", which refer to all the VFS
133 operations and none of the VFS operations respectively.
134 vfs_full_audit records operations in fixed format consisting of fields
136 separated by '|' characters. The format is:
137 smbd_audit: PREFIX|OPERATION|RESULT|FILE
139 The record fields are:
142 • PREFIX - the result of the full_audit:prefix string after
144 variable substitutions
145 • OPERATION - the name of the VFS operation
147 • RESULT - whether the operation succeeded or failed
149 • FILE - the name of the file or directory the operation was
151 performed on
152 This module is stackable.
155
157 full_audit:prefix = STRING
158 Prepend audit messages with STRING. STRING is processed for
159 standard substitution variables listed in smb.conf(5). The default
160 prefix is "%u|%I".
161 full_audit:success = LIST
163 LIST is a list of VFS operations that should be recorded if they
164 succeed. Operations are specified using the names listed above.
165 Operations can be unset by prefixing the names with "!". The
166 default is none operations.
167 full_audit:failure = LIST
169 LIST is a list of VFS operations that should be recorded if they
170 failed. Operations are specified using the names listed above.
171 Operations can be unset by prefixing the names with "!". The
172 default is none operations.
173 full_audit:facility = FACILITY
175 Log messages to the named syslog(3) facility.
176 full_audit:priority = PRIORITY
178 Log messages with the named syslog(3) priority.
179 full_audit:syslog = true/false
181 Log messages to syslog (default) or as a debug level 1 message.
182 full_audit:log_secdesc = true/false
184 Log an sddl form of the security descriptor coming in when a client
185 sets an acl. Defaults to false.
186
188 Log file and directory open operations on the [records] share using the
189 LOCAL7 facility and ALERT priority, including the username and IP
190 address. Logging excludes the open VFS function on failures:
191 [records]
193 path = /data/records
194 vfs objects = full_audit
195 full_audit:prefix = %u|%I
196 full_audit:success = open opendir
197 full_audit:failure = all !open
198 full_audit:facility = LOCAL7
199 full_audit:priority = ALERT

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