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:

o PREFIX - the result of the full_audit:prefix string after variable substitutions

o OPERATION - the name of the VFS operation

o RESULT - whether the operation succeeded or failed

o 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.

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.

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:

[records]         path = /data/records         vfs objects = full_audit         full_audit:prefix = %u|%I         full_audit:success = open opendir         full_audit:failure = all         full_audit:facility = LOCAL7         full_audit:priority = ALERT

VERSION


This man page is correct for version 3.0.25 of the Samba suite.
