How to Enable SSH in Ubuntu 16.04 LTS April 22, 2016 Here’s how to enable Secure Shell (SSH) service in Ubuntu 16.04 Xenial Xerus, the new LTS release, to allow secure remote login and other network communications. Group policies (GPO) allows you to configure BitLocker so that backups of BitLocker keys and recovery keys are stored in computer object in the Active Directory. Each BitLocker recovery object has unique name and contains a globally unique identifier for the recovery password and optionally a package containing the key.
DIY: Immobilizer Hacking for Lost Keys or Swapped ECUHere's how to reprogram your car's engine immobilizer to program new keys in the invent of lost keys or a swapped ECU.DIY Video:Disclaimer:The engine immobilizer is a security device. Use the information provided here in a legal and appropriate manner.Introduction:Modern Toyota and Lexus vehicles use a key with an embedded RFID chip as an added means of theft prevention. The key is read by the computer and if it matches, it will enable all systems to start the car. If the key does not match, the car will only crank but not start.This engine immobilizer system presents a barrier to many owners when it comes time to swap out a bad ECU, or if you’ve lost all the master keys and can't program new keys.While taking the car to a dealership or locksmith is an option, it could get expensive because you are at their mercy. What follows is a cheaper method you can do yourself to “virginize” your ECU to accept new keys. Here’s an overview on how the immobilizer system works on older Toyota and Lexus vehicles.When you insert the key, a coil near the ignition ring picks up the RFID signal from your key and sends it to an amplifier. The amplifier then decrypts it and sends it to the ECU.
Inside the ECU is a 93C56 EEPROM chip (IC900) that stores the key values. If the key code matches the stored values, the engine will start.On newer Toyota and Lexus vehicles, the transponder ECU is a separate unit and it’s housed under the dashboard.The reason for separating the Transponder ECU with the EEPROM storing the keys is that in the invent of lost keys, it would be cheaper for a dealership to replace the Transponder ECU than the Engine Control Unit. However its location under the dash means you will have to remove the entire dash pad. The procedure for reprogramming is similar, however you will have to short two wires on the OBDII port to perform a hand-shaking procedure between the ECUs to program new keys. This is where you need to get a programmer to connect the chip to your PC. You can either buy a USB programmer from eBay or make your own to communicate to the serial port.
In my case, I made my own, using this EEPROM circuit.The components required are fairly basic, three 4.7K ohm resistors, three 5V zener diodes, and a computer with a serial port. To connect the 8-pin EEPROM chip to the computer you'll either have to solder hook-up wires to the pins or get a Test Clip for onboard programming.Note: This is the same circuit for programming the odometer’s EEPROM:Using a test clip helped a lot during prototyping.However the clip doesn’t have a good grip on the SMD chip so I chose to solder wires directly to the leads of the chip.If you do have problems reading and writing from the chip, you have to short the crystal on the board.Here’s the setup, with the computer connected to the ECU via the EEPROM circuit on a prototype breadboard. PonyProg, a free serial device programmer was the software used to read information from the serial port and 'dump' the EEPROM's contents.
First go to setup under options.Select SI Prog I/O, COM 1 and then press Probe to check that the reader is communicating to the software.Then select the device as 93C56 MicroWire EEPROM.Click Read Device to dump the EEPROM’s contents.The content should appear as an array of HEX characters. Each key has a unique 8 digit HEX code. There are also bits to indicate key count, enable programming mode and valet lockout. Here’s a breakdown of an EEPROM dump. After a lot of experimentation, it was observed that there are three distinct keys. Each key is an 8 digit HEX value, repeated three times. It is split across two groups of four, but there is symmetry in their positioning within the dump.With 8 digits and 16 HEX characters, there are 4.2 billion different key combinations.Looking on the right side of the EEPROM dump, there are three noteworthy HEX clusters.The Valet Lockout should be kept as is, FB DF 5A 69.
Erasing this will only allow you to program one Valet key, and then you’re stuck.The virginize keys are values that are “10” in the original dump but must be changed to “00” to tell the computer to go into auto-programming mode.The Key counter is a number count, in inverse HEX, of how many keys are currently stored in the ECU. This must be zeroed as well.Here’s a look-up table to invert HEX. It’s pretty much 0 to F and F to 0 backward. Key Programming:When reconnected to the car, the ECU will be in auto-programming mode and will accept new keys as per the procedure below:1. Briefly insert any key into ignition lock cylinder and remove immediately. The security light should illuminate and remain on.2.
Insert the first transponder key into ignition lock cylinder for registration DO NOT TURN ON. The Security light may blink indicating it has accepted the key.
After 3-5 seconds remove the first key from the ignition. Security light should remain on indicating you're still in programming mode.3. Insert the second transponder key into ignition lock cylinder for registration DO NOT TURN ON. The Security light may blink indicating it has accepted the key. After 3-5 seconds remove the second key from ignition.
Security light should remain on indicating you're still in programming mode.4. Insert third transponder key into ignition lock cylinder for registration DO NOT TURN ON.
After security light goes off remove third key from ignition. The security light should extinguish and then commence to blink regularly.5. Wait 30 seconds for the programming cycle and programming mode to close.The first two keys are internally (inside the ECU) designated as MASTER keys and the 3rd key inserted will be internally designated as the VALET key.As a test, when you insert a MASTER key, the security light should stop blinking right away. If you insert a VALET key, the security light will remain solid for 2 seconds and then go out. If the security light does not stop blinking, that key is not programmed to the car. CompatibilityThis procedure should work on many Toyota and Lexus vehicles from the 1990's to early 2000's. Newer Toyota/Lexus/Scion cars have a separate transponder ECU under the dashboard instead of having the EEPROM store key info in the ECU.
The procedure is similar, though a hand-shaking procedure must be performed between the Transponder ECU and Engine Control Unit before key programming by shorting two wires on the OBDII port for 30 minutes.Reference material:ToyotaNation DIY Writeup:Full PDF download of the procedure. That 8 pins Immobilizer chip. Is there a way clone it? I plan to make a spare ECU for my car. Which in this case.
I'm planning to have 2 different ECU for my car. 1 ecu as backup ready to be swapped incase I brick my ecu. I had my ecu brick on last aug18, It took me months to get it sorted.
After few attempt with incorrect person. Finally I got it done by someone really far away from my country. That is why I want to have spare ecu. Btw my car is 2012 Legacy GT EJ25 Turbo 5EAT tranny with keyless immobiliser.
In corporate segment one of the advantages of BitLocker Drive Encryption technology is the ability to store the Bitlocker recovery keys for encrypted drives in the Active Directory Domain Services (AD DS).BitLocker recovery key is a 48 and/or 256-bit sequence, which is generated during BitLocker installation. When number of the computers in company network is not very large, Administrator can monitor the keys and passwords manually.

But in case when number of machines on the network is more than 100, this task becomes much more complicated. Configure Active Directory to Store BitLocker Recovery KeysGroup policies (GPO) allows you to configure BitLocker so that backups of BitLocker keys and recovery keys are stored in computer object in the Active Directory. Each BitLocker recovery object has unique name and contains a globally unique identifier for the recovery password and optionally a package containing the key. If computer object in Active Directory stores several recovery passwords, the name of data object will contain the date of the creation of a password. Name of the BitLocker recovery object is limited to 64 characters, so the original should be allowed a 48-bit password. Starting from 2008, this extension is available by default, it is still require additional configuration for further functioning.
In schema version of Windows Server 2012 and higher, this functionality works “out of the box”. The same is applicable on the computers running following versions of Windows Server 2016.Let us consider how to configure Active Directory to store BitLocker recovery information.Tip. In Windows Server 2012/2008 BitLocker appears as a BitLocker Drive Encryption feature (not like the client OS).
