In version 1.0.1, we have two libraries to access the Windows registry.

• ​http://www.opengnsys.es/browser/trunk/client/engine/Registry.lib
• ​http://www.opengnsys.es/browser/trunk/client/engine/PostConfEAC.lib

PostconfEAC.lib

To access to Windows registry, this library is oriented to manage a files importer type .reg of Windows.

• Phase 1:
  • Locate all hive (register file) of Microsoft Windows and all users hive.
  • ogLoadHiveWindows(int_disk int_partition)
  • This function exports all system variable: hiveSAM hiveSYSTEM hiveSOFTWARE with the corresponding file path hive.
  • Microsoft Windows user variable will be exported: $user=hiveUserX; hiveUserX=path_to_register_file_user(.dat)

• Phase 2:
  • Compose a file *.reg but with format chntpwd (program Linux to access to Windows registry).
  • This phase may contain all the accesses that we want, the file *.reg with format chntpwd will grown. This allow access multiple to differents hives.
  • Some functions are:
    • ogNTPolUserOn()
    • NTChangeName()
    • NTSetGroupName()
    • NTSetOwner()
    • NTAutoLogon()
    • NTStatusRatonTeclado()
    • NTRunOnceMachine()
    • NTRunUser()
    • NTStatusBootChk()
  • For example, when Windows boots run an instruction, you should call ogHiveNTRunMachine "cmd /c del c:\ogboot.* " ogcleanboot

function ogHiveNTRunMachine (path_script|instruccion idscript) {
   cat >> $TEMPhive << EOF              # Generate a *reg file with format chntpwd.
   h 2                                  # Use hive with id 2. It is corresponding to SYSTEM.
   cd \Microsoft\Windows\CurrentVersion\Run   # Go to corresponding path 
   nv 1 $2                                    # Create a new entry with the name of the parameter2 (identification) 
   ed $2                                      # Edit the entry with:
   $1                                           # Include the path to run scripts or directly the cmd command.
   EOF
}

• Phase 3:
  • Update hive in file *.reg-chntpwd.
  • ogUpdateHiveWindows()

• Example where Windows run an instruction every time it boots.
