VFS_FULL_AUDIT(8)

NAME
vfs_full_audit - record Samba VFS operations in the system log

SYNOPSIS

vfs objects = full_audit

DESCRIPTION

This VFS module is part of thesamba(7) suite.

The vfs_full_audit VFS module records selected client operations to the system log usingsyslog(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.

If an unknown operation name is used (for example an operation name is miss-spelled), the module will fail to load and clients will be refused connections to a share using this module.

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

full_audit:prefix = STRING
    Prepend audit messages with STRING. STRING is processed for standard substitution variables listed insmb.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.

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
