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

In addition to these operations, vfs_full_audit recognizes the
special operation names "all" and "none ", which refer
to all the VFS operations and none of the VFS operations respectively.
vfs_full_audit records operations in fixed format consisting of
fields separated by '|' characters. The format is:
smbd_audit: PREFIX|OPERATION|RESULT|FILE
The record fields are:
•PREFIX - the result of the full_audit:prefix
string after variable substitutions
•OPERATION - the name of the VFS operation
•RESULT - whether the operation succeeded or
failed
•FILE - the name of the file or directory the
operation was performed on
This module is stackable.
full_audit:prefix = STRING
Prepend audit messages with STRING. STRING is processed
for standard substitution variables listed in smb.conf(5). The default
prefix is "%u|%I".
full_audit:success = LIST
LIST is a list of VFS operations that should be recorded
if they succeed. Operations are specified using the names listed above.
Operations can be unset by prefixing the names with "!". The default
is none operations.
full_audit:failure = LIST
LIST is a list of VFS operations that should be recorded
if they failed. Operations are specified using the names listed above.
Operations can be unset by prefixing the names with "!". The default
is none operations.
full_audit:facility = FACILITY
Log messages to the named syslog(3)
facility.
full_audit:priority = PRIORITY
Log messages with the named syslog(3)
priority.
full_audit:syslog = true/false
Log messages to syslog (default) or as a debug level 1
message.
full_audit:log_secdesc = true/false
Log an sddl form of the security descriptor coming in
when a client sets an acl. Defaults to false.
Log file and directory open operations on the [records] share using the LOCAL7
facility and ALERT priority, including the username and IP address. Logging
excludes the open VFS function on failures:
[records]
path = /data/records
vfs objects = full_audit
full_audit:prefix = %u|%I
full_audit:success = open opendir
full_audit:failure = all !open
full_audit:facility = LOCAL7
full_audit:priority = ALERT
This man page is part of version 4.13.17 of the Samba suite.
The original Samba software and related utilities were created by Andrew
Tridgell. Samba is now developed by the Samba Team as an Open Source project
similar to the way the Linux kernel is developed.
