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 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:

       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
