This VFS module is part of the

.PP
The
\FCvfs_smb_traffic_analyzer\F[]
VFS module logs client write and read operations on a Samba server and sends this data over a socket to a helper program, which feeds a SQL database\&. More information on the helper programs can be obtained from the homepage of the project at: http://holger123\&.wordpress\&.com/smb\-traffic\-analyzer/
.PP
\FCvfs_smb_traffic_analyzer\F[]
currently is aware of the following VFS operations:

.PP
This module is stackable\&.
.SH "OPTIONS"
.PP
smb_traffic_analyzer:mode = STRING
.RS 4
If STRING matches to "unix_domain_socket", the module will use a unix domain socket located at /var/tmp/stadsocket, if STRING contains an different string or is not defined, the module will use an internet domain socket for data transfer\&.
.RE
.PP
smb_traffic_analyzer:host = STRING
.RS 4
The module will send the data to the system named with the hostname STRING\&.
.RE
.PP
smb_traffic_analyzer:port = STRING
.RS 4
The module will send the data using the TCP port given in STRING\&.
.RE
.PP
smb_traffic_analyzer:anonymize_prefix = STRING
.RS 4
The module will replace the user names with a prefix given by STRING and a simple hash number\&.
.RE
.PP
smb_traffic_analyzer:total_anonymization = STRING
.RS 4
If STRING matches to \'yes\', the module will replace any user name with the string given by the option smb_traffic_analyzer:anonymize_prefix, without generating an additional hash number\&. This means that any transfer data will be mapped to a single user, leading to a total anonymization of user related data\&.

.SH "VERSION"
.PP
This man page is correct for version 3\&.3 of the Samba suite\&.
.SH "AUTHOR"
.PP
The 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\&.
.PP
The original version of the VFS module and the helper tools were created by Holger Hetterich\&.
