NAME¶
vfs_full_audit - record Samba VFS operations in the system log
SYNOPSIS¶
vfs objects = full_audit
DESCRIPTION¶
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:
aio_cancel
aio_error

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.
OPTIONS¶
vfs_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".
vfs_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 "!".
vfs_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 "!".
full_audit:facility = FACILITY
Log messages to the named
syslog(3)
facility.
full_audit:priority = PRIORITY
Log messages with the named
syslog(3)
priority.
EXAMPLES¶
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

suite.
