+
==Analyst Desktop==
−
Truxton is made up of different kinds of processes running in the ETL layer.
+
One of the things to turn off is the automatic <code>ANALYZE</code> when the desktop starts.
−
Some processes makes sense to have many instances of while others only require a single instance.
+
This is controlled by the <code>skip_update_db_stats_on_boot</code> desktop setting.
 +
Edit the <code>%localappdata%\probity\truxton\client.settings</code> file.
 +
Search for <code>skip_update_db_stats_on_boot</code> value.
 +
It should look like this:
 +
<pre>
 +
  "skip_update_db_stats_on_boot": {
 +
    "OriginalType": "System.Boolean, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e",
 +
    "Data": "false"
 +
  },
 +
</pre>
 +
 
 +
Change the <code>Data</code> field to <code>true</code>
 +
<pre>
 +
  "skip_update_db_stats_on_boot": {
 +
    "OriginalType": "System.Boolean, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e",
 +
    "Data": "true"
 +
  },
 +
</pre>
 +
 
 +
==Server Architectures==
 +
With seven machines dedicated to forensic processing, we have a flexible platform to configure in a variety of ways.
 +
 
 +
===Laptop===
 +
The "laptop" architecture uses the servers as seven individual machines.
 +
Each server hosts everything needed to run Truxton.
 +
The disadvantage of this configuration is that the other machines in the rack cannot help to process the data being loaded.
 +
 
 +
===2x5===
 +
This configuration will dedicate two machines to database and message bus.
 +
The remaining 5 machines cooperate in exploiting the media being loaded.

There should be only one [[Les]] on the rack and the [[Truxton_Status|Truxton Status Monitor tray application]] is something for a human to look at.

# Make sure FIPS mode is off
+
# Make sure FIPS mode is off. [https://en.wikipedia.org/wiki/FIPS_140 FIPS] is a standard for secure computing. When Windows FIPS mode is on, it makes sure that only approved cryptographic algorithms are used for high level tasks like signing documents or encrypting files. Specifically, Windows will disable the use of non-approved algorithms. The problem is, Microsoft gave developers a [https://en.wikipedia.org/wiki/Microsoft_CryptoAPI Crypto API] that provided a common approach to low level tasks such as hashing. Other libraries (like [https://en.wikipedia.org/wiki/.NET_Framework .Net]) depend on the Crypto API for performing [https://en.wikipedia.org/wiki/MD5 MD5] hashing. When FIPS mode is on, MD5 is no longer part of the Crypto API and any code that relied on the Crypto API is now broken. This can lead to many hours of developer hilarity figuring out why programs stop working...

==Useful Batch Files==
+
==Rack Management==
−
When working on the rack, life is made easier through the use of scripts.
+
There is a folder in the clustered storage named <code>Rack Management</code> which contains scripts and configuration files to ease the management of the rack.
  
−
===Remove Permissions===
+
===Configurations===
−
Here's the Powershell script to remove security from a folder.
+
This sub-folder is home to the customized versions of <code>[[TruxtonService.xml]]</code> and <code>TruxtonSettings.xml</code> for each node.
−
<syntaxhighlight lang="powershell">
+
The naming convention for the files is the rack address, underscore, last octet of the server's IP address, underscore, and XML filename.
−
$folder_path = "D:\Temp"
+
For example, the <code>TruxtonSettings.xml</code> file to be used on the U01 machine at 10.10.182.131 will be named <code>U01_131_TruxtonSettings.xml</code>
−
$security_descriptor = Get-Acl -Path $folder_path
 
  
−
# This is the SDDL for a NULL DACL
+
Create a new sub-folder for each configuration you want the rack to use.
−
$sddl_for_a_null_dacl = ""
+
The default configuration is in a sub-folder named <code>Nodes</code>
  
−
$security_descriptor.SetSecurityDescriptorSddlForm($sddl_for_a_null_dacl)
+
===Installing Truxton===
−
Set-Acl -Path $folder_path -AclObject $security_descriptor
+
The <code>InstallTruxton.cmd</code> batch file will install the latest version of Truxton onto the machines in the rack.
−
</syntaxhighlight>
+
It assumes that Truxton is not running on the rack.
 +
You can stop Truxton by using the <code>[[#Stopping Truxton|StopTruxton.cmd]]</code> batch file.

Some pointers on tuning loader machines.

Single Machine

Also known as a "laptop" configuration.

Install

We recommend you install Truxton on each loader node as follows:

  1. On the D: drive, make the following folders:
    1. Hashsets
    2. Temp
    3. Truxton Data\Search (this is actually two folders)
  2. Run the PostgreSQL installer (postgresql-12.4.1-windows-x64.exe in the Prerequisites folder of the installation media). Use the following settings:
    1. Data Directory: D:\Truxton Data\data
    2. Password: Truxton4n6
    3. Locale to be used: C
  3. Run Truxton_Installer.exe, do not use the defaults
    1. Change the "Depot Data Directory" to D:\Truxton Data

Temporary Folder

The tempdir setting controls the folder where Truxton ETLs will write their temporary files. In the case of PST files, this can be huge. Choose a fast drive to hold this.

Hashsets

The hashsetdir setting controls the folder where hashsets are stored. Any ETL process that produces files will need fast access to the files in this folder. Many reads will be performed on these files so this folder should be on a fast drive.

Truxton Forensic Rack

The Truxton Forensic Rack is a 7 foot tall rack populated with hardware dedicated to forensic processing. It has a Yellowbrick database appliance, seven dedicated loader/exploitation machines and 1PB of usable depot storage. With everything separated, it gives us many ways to configure processing.

Hardware

Here's how the hardware is stacked:

U42 Network Switch
U27 Yellowbrick
U26 Yellowbrick Manager 0
U25 Yellowbrick Manager 1
U23 KVM Server
U22 Keyboard and Monitor
U13 Loader Node 7
U11 Loader Node 6
U09 Loader Node 5
U07 Loader Node 4
U05 Loader Node 3
U03 Loader Node 2
U01 Loader Node 1

Analyst Desktop

One of the things to turn off is the automatic ANALYZE when the desktop starts. This is controlled by the skip_update_db_stats_on_boot desktop setting. Edit the %localappdata%\probity\truxton\client.settings file. Search for skip_update_db_stats_on_boot value. It should look like this: 

  "skip_update_db_stats_on_boot": {
    "OriginalType": "System.Boolean, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e",
    "Data": "false"
  },

Change the Data field to true 

  "skip_update_db_stats_on_boot": {
    "OriginalType": "System.Boolean, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e",
    "Data": "true"
  },

Server Architectures

With seven machines dedicated to forensic processing, we have a flexible platform to configure in a variety of ways.

Laptop

The "laptop" architecture uses the servers as seven individual machines. Each server hosts everything needed to run Truxton. The disadvantage of this configuration is that the other machines in the rack cannot help to process the data being loaded.

2x5

This configuration will dedicate two machines to database and message bus. The remaining 5 machines cooperate in exploiting the media being loaded.

Loader Node 1 (U01)

This machine hosts the singleton processes and low-volume processes.

  1. Load Status Monitor
  2. Message Bus
  3. SOLR Server
  4. Alert
  5. Identify
  6. Poly
  7. Report
  8. SOLR
  9. SOLRFile

Loader Node 2 (U03)

  1. Postgres Database Server - Configured for 1,000 connections
  2. Finished

Loader Nodes 3-7 (U05-U13)

These are the machines with lots to do. They host:

  1. Expand
  2. Poly File Expander
  3. Archives
  4. File Carver
  5. Video Contact Sheet
  6. EMail Parsing
  7. Load

Maintenance

Steps to Update Truxton on a Loader Node

  1. Stop the Truxton Service 
    net stop truxton
  2. Uninstall Truxton
  3. Install new Truxton
  4. Stop Les 
    net stop les
  5. Stop the Truxton Service 
    net stop truxton
  6. Click on the Truxton Status Monitor icon in the Windows Status Bar and select "Exit"
  7. Validate that TruxtonService.xml and TruxtonSettings.xml are correct
  8. In the Services application, select the properties of "Truxton Monitor (Les)" and change the Startup Type to "Disabled"
  9. Start the Truxton Service 
    net start truxton

There should be only one Les on the rack and the Truxton Status Monitor tray application is something for a human to look at.

Machine IDs

Normally the machine identifier is derived from the operating system but in a rack situation we sacrifice some entropy to provide system administrators assistance. The Machine ID for rack configurations are made up of the following fields:

Field Length Meaning
Rack 2 bytes 5452 TR for Truxton Rack
Rack Serial Number 2 bytes The serial number of the rack in hex encoded decimal
Rack Address Indicator 1 byte 55 U
Rack Address 1 byte Unit address in the rack of the machine
Logical Processors 2 bytes The number of logical CPUs in the machine
RAM 2 bytes The number of gigabytes of RAM in the machine
IP Address 6 bytes The IP address of the machine

For Example a Rack Machine ID of 54520001-5501-0072-0191-010010182131 tells us:

Bytes Meaning
5452 ASCII TR, this is a Rack Machine ID
0001 Serial Number 1
55 Unit Address
01 The machine is in slot U01 in the rack
0072 The machine has 72 logical processors
0191 The machine has 191GB of RAM
010010182131 The IP address of the machine is 10.10.182.131

The Machine ID corresponds to the [MachineID] column of the [Statistics] table. This allows you to see how the different machines perform their loads. Rack serial numbers in the 9000 range are development racks where new configurations are tested.

Loader Node Configuration Files

A pair of configuration files TruxtonSettings.xml and TruxtonService.xml are created and saved to make installation easy on virgin machines. TruxtonSettings.xml identifies the loader node and where the database and depots are. TruxtonService.xml governs which ETL processes will run on that machine.

Low-Volume Host

Low-volume is defined as something that isn't used very often. When it is, there's not much impact on the performance of this host machine. A low-volume ETL won't produce very many of anything.

TruxtonService.xml

The following is a sample configuration file for low-volume host. 

<root>

Loader Node Installation Checklist

Here are the steps for installing Truxton as a loader node on the rack. We recommend that each loader node have an SSD dedicated to Truxton. This SSD, we will call it the D: drive, can be in the 200GB range or larger. Truxton will use it to host the hashsets and for temporary files. We do this because hashsets require a lot of seek and reads. If it is on an SSD, the speed will be dramatically improved over having it on a shared folder. Likewise, the temporary files folder should be on an SSD for improved IO performance.

  1. Make sure FIPS mode is off. FIPS is a standard for secure computing. When Windows FIPS mode is on, it makes sure that only approved cryptographic algorithms are used for high level tasks like signing documents or encrypting files. Specifically, Windows will disable the use of non-approved algorithms. The problem is, Microsoft gave developers a Crypto API that provided a common approach to low level tasks such as hashing. Other libraries (like .Net) depend on the Crypto API for performing MD5 hashing. When FIPS mode is on, MD5 is no longer part of the Crypto API and any code that relied on the Crypto API is now broken. This can lead to many hours of developer hilarity figuring out why programs stop working...
  2. Create C:\ProgramData\Truxton\Settings folder
  3. Copy the two configuration files into the Settings folder
  4. Modify the TruxtonSettings.xml file to set the machineid, set the rack and IP address fields
  5. Install Truxton
    1. Run Truxton_Installer.exe
    2. If asked "Should I install Java?" click the "No" button. Do not install Java
    3. If asked "Should I install PostgreSQL Database Server?" click the "No" button. Do not install PostgreSQL
    4. When asked "Would you like to use the default options when installing Truxton?" click the "Yes" button. Yes install with the default options (since we copied the settings files already)
  6. Stop the Truxton service
  7. Stop Les
  8. Set Les (Truxton Monitor) service to be Disabled from the Windows Services control panel.
  9. Create D:\Hashsets folder
  10. Create the D:\Temp folder
  11. Remove permissions from D:\Temp so the ETL processes can write to it.
  12. Copy the hashsets from the installation media to D:\Hashsets
  13. Restart the Truxton service
  14. Exit the tray app

Rack Management

There is a folder in the clustered storage named Rack Management which contains scripts and configuration files to ease the management of the rack.

Configurations

This sub-folder is home to the customized versions of TruxtonService.xml and TruxtonSettings.xml for each node. The naming convention for the files is the rack address, underscore, last octet of the server's IP address, underscore, and XML filename. For example, the TruxtonSettings.xml file to be used on the U01 machine at 10.10.182.131 will be named U01_131_TruxtonSettings.xml

Create a new sub-folder for each configuration you want the rack to use. The default configuration is in a sub-folder named Nodes

Useful Batch Files

Remove Permissions

Here's the PowerShell script to remove security from a folder. 

$folder_path = "D:\Temp"
$security_descriptor = Get-Acl -Path $folder_path

# This is the SDDL for a NULL DACL
$sddl_for_a_null_dacl = ""

$security_descriptor.SetSecurityDescriptorSddlForm($sddl_for_a_null_dacl)
Set-Acl -Path $folder_path -AclObject $security_descriptor

Storage Spaces Direct

The Truxton rack uses Microsoft's Storage Spaces Direct (aka S2D) for managing disk space.

Planning Volumes

Here is a calculator to use when planning on creating a volume.

Creating a Volume

Here's how to create a 64TB volume for depots using the Powershell command New-Volume 

New-Volume -FriendlyName "GoldCopy" -Size 250TB -ResiliencySettingName Mirror -NumberOfDataCopies 2 -FileSystem CSVFS_ReFS -StoragePoolFriendlyName S2D*

Repairing a Volume

Sometimes you may see "Needs Repair" as its status.
