NAMEvfs_full_audit - record Samba VFS operations in the system logSYNOPSISvfs objects = full_audit
DESCRIPTIONThis 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:chdir

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 •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
OPTIONSfull_audit:prefix = STRINGPrepend 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 all 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 all 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.
EXAMPLESLog 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 VERSIONThis man page is part of version 4.8.7 of the Samba suite.AUTHORThe 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.
