<title>DESCRIPTION</title>
<para>This VFS module is part of the
<citerefentry><refentrytitle>samba</refentrytitle>
<manvolnum>7</manvolnum></citerefentry> suite.</para>
<para>The <command>vfs_smb_traffic_analyzer</command> 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/
</para>
<para><command>vfs_smb_traffic_analyzer</command> currently is aware
of the following VFS operations:</para>
<simplelist>
<member>write</member>
<member>pwrite</member>
<member>read</member>
<member>pread</member>
</simplelist>
<para><command>vfs_smb_traffic_analyzer</command> sends the following data
in a fixed format seperated by a comma through either an internet or a
unix domain socket:</para>
<programlisting>
BYTES|USER|DOMAIN|READ/WRITE|SHARE|FILENAME|TIMESTAMP
</programlisting>
<para>Description of the records:
<itemizedlist>
<listitem><para><command>BYTES</command> - the length in bytes of the VFS operation</para></listitem>
<listitem><para><command>USER</command> - the user who initiated the operation</para></listitem>
<listitem><para><command>DOMAIN</command> - the domain of the user</para></listitem>
<listitem><para><command>READ/WRITE</command> - either "W" for a write operation or "R" for read</para></listitem>
<listitem><para><command>SHARE</command> - the name of the share on which the VFS operation occured</para></listitem>
<listitem><para><command>FILENAME</command> - the name of the file that was used by the VFS operation</para></listitem>
<listitem><para><command>TIMESTAMP</command> - a timestamp, formatted as "yyyy-mm-dd hh-mm-ss.ms" indicating when the VFS operation occured</para></listitem>

<title>OPTIONS</title>
<variablelist>
<varlistentry>
<term>smb_traffic_analyzer:mode = STRING</term>
<listitem>
<para>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.</para>
</listitem>
</varlistentry>
<varlistentry>
<term>smb_traffic_analyzer:host = STRING</term>
<listitem>
<para>The module will send the data to the system named with
the hostname STRING.</para>
</listitem>
</varlistentry>
<varlistentry>
<term>smb_traffic_analyzer:port = STRING</term>
<listitem>
<para>The module will send the data using the TCP port given
in STRING.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>smb_traffic_analyzer:anonymize_prefix = STRING</term>
<listitem>
<para>The module will replace the user names with a prefix
given by STRING and a simple hash number.
</para>
</listitem>
</varlistentry>
<varlistentry>
<term>smb_traffic_analyzer:total_anonymization = STRING</term>
<listitem>
<para>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.</para>
