Photorec

PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its ‘Photo Recovery’ name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media’s filesystem has been severely damaged or re-formatted.

PhotoRec is free, this open source multi-platform application is distributed under GNU Public License. PhotoRec is a companion program to TestDisk, an app for recovering lost partitions on a wide variety of filesystems and making non-bootable disks bootable again.

Partedmagic

Parted Magic is a Linux LiveCD/USB/PXE with its elemental purpose being to partition hard drives and is not designed to be a “Rescue CD” nor is it based on another Distribution.

Optimized at approximately 45MB, the Parted Magic OS employs core programs of GParted and Parted to handle partitioning tasks with ease, while featuring other useful programs (e.g. Partition Image, TestDisk, fdisk, sfdisk, dd, ddrescue, etc.) and an excellent set of documentation to benefit the user. An extensive collection of fileystem tools are also included, as Parted Magic supports the following: ext2, ext3, ext4, fat16, fat32, hfs, hfs+, jfs, linux-swap, ntfs, reiserfs, reiser4, and xfs.

The latest version is updated with: Linux 2.6.24.3, Parted 1.8.8, ntfsprogs-2.0.0, ntfs-3g-1.2506, and GParted-0.3.7.

Parted Magic uses Busybox for basic Unix commands and networking, the Dropbear SSH server and client, and Firefox to surf the web.

The current Xserver is xorg-server-1.4.0.90 with the following drivers: apm, ark, ati, chips, cirrus, cyrix, glint, i128, i740, i810, mga, neomagic, nv, r128, riva128, radeon, rendition, s3, s3virge, savage, siliconmotion, sis, tdfx, tga, trident, tseng, vesa, vmware, and voodoo.

The mini Xserver, Xvesa, is also available.

TestDisk

TestDisk is a powerful free data recovery software! It was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally deleting a Partition Table). Partition table recovery using TestDisk is really easy.

Foremost

Foremost is a console program to recover files based on their headers, footers, and internal data structures. This process is commonly referred to as data carving. Foremost can work on image files, such as those generated by dd, Safeback, Encase, etc, or directly on a drive. The headers and footers can be specified by a configuration file or you can use command line switches to specify built-in file types. These built-in types look at the data structures of a given file format allowing for a more reliable and faster recovery.

Scalpel

Scalpel is a fast file carver that reads a database of header and footer definitions and extracts matching files from a set of image files or raw device files. Scalpel is filesystem-independent and will carve files from FATx, NTFS, ext2/3, or raw partitions. It is useful for both digital forensics investigation and file recovery. Scalpel resulted from a complete rewrite of foremost 0.69, a popular open source file carver, to enhance performance and decrease memory usage.

The Sleuth Kit

The Sleuth Kit (previously known as TASK) is a collection of UNIX-based command line file and volume system forensic analysis tools. The file system tools allow you to examine file systems of a suspect computer in a non-intrusive fashion. Because the tools do not rely on the operating system to process the file systems, deleted and hidden content is shown.

The volume system (media management) tools allow you to examine the layout of disks and other media. The Sleuth Kit supports DOS partitions, BSD partitions (disk labels), Mac partitions, Sun slices (Volume Table of Contents), and GPT disks. With these tools, you can identify where partitions are located and extract them so that they can be analyzed with file system analysis tools.

When performing a complete analysis of a system, we all know that command line tools can become tedious. The Autopsy Forensic Browser is a graphical interface to the tools in The Sleuth Kit, which allows you to more easily conduct an investigation. Autopsy provides case management, image integrity, keyword searching, and other automated operations.

Provides a host of functions for recovering data from damaged file systems of all kinds http://www.partitionsupport.com/utilities.htm

lately I have been experiencing problems with .NET, specifically problems uninstalling .NET 2 and 3. Below is a great tool used to uninstall all instances of .NET

http://www.malwaredomainlist.com/ is a good site to go to if you want to check if a certain site is known to have malware present.

I figured it out here is what i did:

<?php
$fn = “file.txt”;
$file = fopen($fn, “a+”);
$size = filesize($fn);
$space.= “\n”;
if($_POST[’addition’]) fwrite($file, $_POST[’addition’]);

$text = fread($file, $size);
fwrite ($file, $space);
fclose($file);
?>
<form action=”<?=$PHP_SELF?>” method=”post”>
<input type=”text” name=”addition”/><br/>
<input type=”submit”/>
</form>

file is the text file that you will add to

If you want to force a heart beat on an ISS G200 issue the following command while you have an ssh connection and logged in as root:

service iss-spa doheartbeat

If you are having whitespace issues in bash look at this link:

I checked my logs in windows 2003 R2 Standard Edition and received the following error:

Automatic certificate enrollment for local system failed to enroll for one Domain Controller certificate (0×80070005).  Access is denied.

To solve this error i did the following:

gave system and administrators full control of:
C:\Documents and Settings\All Users\Application Data\Microsoft\Crypto\RSA\MachineKeys

added domain controllers to CERTSVC_DCOM_ACCESS
This seemed to fix the problem for me

If you installed the default Proventia Server 2.0 install you will notice that many of the features are locked down. For instance you cant restart
services or uninstall the program. If you need to restart the service issue the following command:

RapApp -ap

To do this open up cmd and browse to c:\program files\ISS\Proventia Server\

once you are there issue “rapapp -ap” without the quotes

If you need to deploy printers in an AD environment and have Windows 2003 R2 here is a great article:

http://www.windowsnetworking.com/articles_tutorials/Deploying-Printers-Group-Policy-Windows-R2.html

This will give you all the details necessary to deploy printers remotely.  Also the print manager is needed and can be installed through windows add/remove programs.  You will need the 2nd install CD of Windows 2003 R2

if you ever want to check the link speed for linux the easiest way is to issue the following command:

dmesg | grep 100

this will bring up anything with 100mb or higher so if you have a 10mb NIC or think you do change it to 10 instead of 100.
