- Graphical grub2 Configuration Manager - Grub Customizer

The goal of Grub Customizer is to create a complete and intuitive graphical grub2/burg configuration interface. The main feature is the boot entry list configuration - but not simply by modified the grub.cfg: to keep the dynamical configuration, this application will only edit the script order and generate proxies (script output filter), if required. To get more information about how it works, look here: https://answers.launchpad.net/grub-customizer/+faq/1355.
Version 2.0 introduces the ability to change the grub2/burg setting like the default entry, timeouts, menu visibility, screen resolution, background image and colors (grub2 only) and much more.

Since version 1.5 you can use it to repair and configure grub2/burg using a live cd (and Grub Customizer, which has to be installed as usual at the live system before using it). All the required partitions will be automatically mounted when choosing the root partition and some sub partitions on the "partition chooser" (a dialog which pops up, when you start Grub Customizer inside a live system).

- How to Hide data (Steganography) into MP3 file - mp3stego

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, suspects the existence of the message, a form of security through obscurity

MP3Stego will hide information in MP3 files during the compression process. The data is first compressed, encrypted and then hidden in the MP3 bit stream. Although MP3Stego has been written with steganographic applications in mind it might be used as a copyright marking system for MP3 files (weak but still much better than the MPEG copyright flag defined by the standard). Any opponent can uncompress the bit stream and recompress it; this will delete the hidden information – actually this is the only attack we know yet – but at the expense of severe quality loss.

- Install Many Linux Distributions from one disk - NetbootCD

NetbootCD is a GNU/Linux live CD based on Tiny Core Linux. The live CD allows the user to download and run one of several Linux netboot installers, which can install a full GNU/Linux system with only a hard drive and Internet connection.

Several of the distributions supported by NetbootCD are prerelease distributions (such as Debian testing) or development distributions (openSUSE Factory, Fedora Rawhide, Debian sid.) Because NetbootCD downloads the latest installer, which in turn downloads the latest system components, you can install a fully up-to-date system without burning a new CD.

- Testing Cross Site Scripting Vulnerability - XSSer

Cross-site scripting (XSS) is a type of computer security vulnerability typically found in Web applications that enables attackers to inject client-side script into Web pages viewed by other users.

A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same origin policy. Cross-site scripting carried out on websites accounted for roughly 80% of all security vulnerabilities documented by Symantec as of 2007. Their effect may range from a petty nuisance to a significant security risk, depending on the sensitivity of the data handled by the vulnerable site and the nature of any security mitigation implemented by the site's owner.

XSSer is an open source penetration testing tool that automates the process of detecting and exploiting XSS injections against different applications.

It contains several options to try to bypass certain filters, and various special techniques of code injection.

XSSer Features
 * Added “final remote injections” option
 * Cross Flash Attack!
 * Cross Frame Scripting
 * Data Control Protocol Injections
 * Base64 (rfc2397) PoC
 * OnMouseMove PoC
 * Browser launcher
 * New options menu
 * Pre-check system
 * Crawler spidering clones
 * More advanced statistics system
 * “Mana” ouput results

- Load / Performance Testing Web Application - Httperf

Httperf is a tool for measuring web server performance. It provides a flexible facility for generating various HTTP workloads and for measuring server performance.

The focus of httperf is not on implementing one particular benchmark but on providing a robust, high-performance tool that facilitates the construction of both micro- and macro-level benchmarks. The three distinguishing characteristics of httperf are its  ...
 * Robustness, which includes the ability to generate and sustain server overload
 * Support for the HTTP/1.1 and SSL protocols
 * Extensibility to new workload generators and performance measurements.

The purpose of httperf is to help answer a number of complex or otherwise hard to investigate questions. For instance, it is usually desirable when designing and programming a website to be interested in how well it will perform under a variety of circumstances.  When investigating whether or not to invest in faster equipment, many people want to know the limits to which their current hardware can perform. This is what httperf is designed to help answer.

- Large-Scale File Distribution Application - Zsync

Zsync is a file transfer program. It allows you to download a file from a remote server, where you have a copy of an older version of the file on your computer already. zsync downloads only the new parts of the file. It uses the same algorithm as rsync. However, where rsync is designed for synchronizing data from one computer to another within an organization, zsync is designed for file distribution, with one file on a server to be distributed to thousands of down-loaders. zsync requires no special server software just a web server to host the files and imposes no extra load on the server, making it ideal for large scale file distribution.

Advantages of zsync
zsync fills a gap in the technology available for large-scale file distribution. Three key points explain why zsync provides a genuinely new technique for file distribution:

 * Client-side rsync: zsync uses the rsync algorithm, but runs it on the client side, thus avoiding the high server load associated with rsync.
 * Rsync over HTTP: zsync provides transfers that are nearly as efficient as rsync -z or cvsup, without the need to run a special server application. All that is needed is an HTTP/1.1-compliant web server. So it works through firewalls and on shared hosting accounts, and gives less security worries.
 * Handling for compressed files: rsync is ineffective on compressed files, unless they are compressed with a patched version of gzip. zsync has special handling for gzipped files, which enables update transfers of files which are distributed in compressed form.

- HTML Syntax Checker and Reformatter - Tidy

When editing HTML it's easy to make mistakes. Wouldn't it be nice if there was a simple way to fix these mistakes automatically and tidy up sloppy editing into nicely layed out markup? Well now there is! Dave Raggett's HTML TIDY is a free utility for doing just that. It also works great on the atrociously hard to read markup generated by specialized HTML editors and conversion tools, and can help you identify where you need to pay further attention on making your pages more accessible to people with disabilities.

Tidy is able to fix up a wide range of problems and to bring to your attention things that you need to work on yourself. Each item found is listed with the line number and column so that you can see where the problem lies in your markup. Tidy won't generate a cleaned up version when there are problems that it can't be sure of how to handle. These are logged as "errors" rather than "warnings".

- How To Setup Streaming Music Server - Zeya

Zeya is a lightweight music streamer. It's written in Python and Javascript which means it does not require as much resources as Java based streamers would need. Zeya uses about 10-20MB ram idle. When there is music streamed from the server to you there is a trans-coding process which uses also a tad of ram, but don't expect it to hit above the 80MB ram.

To play music from your server you need a browser which supports HTML5. The browsers which are known to work with Zeya are:
 * Mozilla Firefox 3.5 or later
 * Google Chrome or Chromium
 * Internet Explorer 6, 7 and 8 on Windows with the Google Chrome Frame plugin

The client runs in any browser that supports a certain subset of the HTML 5 technologies— no Flash needed. No Silverlight, no applets, no plugins, no external players.

- Tool for Detecting Memory Management Problems in Programs - Valgrind

Valgrind is a powerful tool for detecting memory management problems in programs. The kinds of problems it can detect are often very difficult to find by other means and often cause difficult to diagnose crashes. Valgrind can be used with existing executables without recompiling or relinking, although the output it produces will be much more useful if you have compiled with the -g flag.

Valgrind Capabilities
Valgrind is basically an x86 emulator that checks all reads and writes of memory, intercepts all calls to allocate and deallocate memory. The memcheck tool of valgrind (which is the main tool and the only one covered in this chapter) can detect the following:

 * Use of uninitialized memory
 * Reading/writing memory after it has been free'd
 * Reading/writing off the end of malloc'd blocks
 * Reading/writing inappropriate areas below the stack.
 * Memory leaks
 * Mismatched use of malloc/new/new[] vs free/delete/delete[]
 * Overlapping src and dst pointers in memcpy() and related functions
 * Doubly freed memory
 * Passing unaddressable bytes to a system call

- Multimedia (MP3, MPEG-4, AVI, DiVX, etc.) support in Ubuntu 11.10 (Oneiric Ocelot)

Why doesn’t Ubuntu support MP3 ‘out of the box’?

Ubuntu cannot include support for MP3 or DVD video playback or recording. MP3 formats are patented, and the patent holders have not provided the necessary licenses. Ubuntu also excludes other multimedia software due to patent, copyright, or license restrictions, such as Adobe Flash Player and RealNetworks RealPlayer.

That doesn’t mean you can’t play .mp3 files in Ubuntu , it just takes a bit of work (not much).

Follow these instructions to get mp3 and other multimedia support on your Ubuntu 11.10.

- Extracting Images from PDF files - Pdfimages

Pdfimages is an open source command-line utility for extracting images from PDF files. It is freely available as part of poppler-utils and xpdf-utils, and included by default with many Linux distributions.

Pdfimages saves images from a Portable Document Format  (PDF)  file  as Portable Pixmap (PPM), Portable Bitmap (PBM), or JPEG files. Pdfimages  reads  the  PDF file, scans one or more pages, PDF-file, and writes one PPM, PBM, or JPEG file for each  image,  image-root-nnn.xxx, where  nnn  is  the image number and xxx is the image type (.ppm, .pbm,.jpg).

NB: pdfimages extracts the raw image data from the  PDF  file,  without performing  any  additional  transforms.  Any rotation, clipping, color inversion, etc. done by the PDF content stream is ignored.

Tomahawk is build to solve below mentioned problems:
 * Why can't I easily listen to all the music I have scattered across multiple computers, at multiple locations, from a single interface?
 * Why can I stream my home iTunes library to my laptop when I am at home, but I can't when I am somewhere else?
 * Conversely, how come I can stream my co-worker's iTunes library when we are both at the office, but only if we are on the same wireless network (or subnet)?
 * When I am reading a website that talks about a song, and I own that song, why can't I play my copy directly from that page?
 * Why can't I subscribe to, and import, playlist metadata from all over the web - and then have that resolve against any/all songs that I have access to?
 * Why do I have to listen to songs I have on my hard drive, and songs from services I subscribe to, in totally different user experience silos?
 * If I am a music subscription service provider, why do I need to incur the costs of streaming you content you already have locally?

- Text Based Password Manager using the Blowfish Encryption - YAPET

YAPET is a text based password manager using the Blowfish encryption algorithm to store password and associated information encrypted on disk. Its primary aim is to provide a safe way to store passwords in a file on disk while having a small footprint, and compiling and running under today's most popular Unix Systems.

YAPET does not impose a limit of password records per file and the number of files the passwords are stored in, although YAPET is only able to display password records of one file at a time. For convenience, YAPET provides a search function for password records of the currently displayed password file.

The password records are protected by a master password. The master password is used to encrypt and decrypt the password records.

YAPET relies on OpenSSL for encrypting and decrypting password records. The cipher for encryption and decryption is Blowfish with a 448 bits key.

- openSUSE 12.1 Released

openSUSE 12.1
This release represents more than eight months of work by international community.
Awesome improvements include the latest GNOME 3.2 desktop as well as the newest from KDE, XFCE and LXDE; your ownCloud made easy with mirall; Snapper-shots of your file system; and much, much more.

Desktops:
openSUSE 12.1 comes with the new GNOME Shell 3.2.
Notifications are much nicer, you can now configure your online accounts in one place and Shell handles multiple-screen setups better.

Among the features is color management, something GNOME shares with KDE where openSUSE is the first to integrate the Oyranos color management system. Also new from KDE is Apper, an easier-to-use PackageKit front end.

Cloud:
It is 2011, and most of us use ‘cloud’ technology like having our files on Dropbox, friends on Facebook and music on Spotify. But these technologies are arguably dangerous from a security and privacy point of view. While not solving all problems yet, ownCloud aims to bring these services back under your control.

- How To Set the Disk IO Priority For a Process on Linux - ionice

ionice program sets or gets the io scheduling class and priority for a program. If no arguments or just -p is given, ionice will query the current io scheduling class and priority for that process.

A process can be in one of three scheduling classes:
Idle
A program running with idle io priority will only get disk time when no other program has asked for disk io for a defined grace period. The impact of idle io processes on normal system activity should be zero. This scheduling class does not take a priority argument. This scheduling class is permitted for an ordinary user (since kernel 2.6.25).
Best effort
This is the effective scheduling class for any process that has not asked for a specific io priority. This class takes a priority argument from 0-7, with lower number being higher priority. Programs running at the same best effort priority are served in a round-robin fashion.

The  checksecurity  command scans the mounted files systems (subject to the filter defined in /etc/checksecurity.conf) and compares the list of setuid  programs  to  the list created on the previous run. Any changes are printed to standard output. Also, it generates a list  of  nfs  and afs  filesystems that are mounted insecurely (i.e. they are missing the nodev and either the noexec or nosuid flags).

checksecurity is run by cron on a daily basis, and the output stored in /var/log/setuid/setuid.changes.

Checksecurity Installation:
Under Ubuntu Linux, open the terminal and type following command to install checksecurity:
sudo apt-get install checksecurity

- Automatic SQL Injection Exploitation Tool - TheMole

Author is not responsible for any damage or illegal actions caused by the use of this program.
Use on your own risk!

SQL injection is yet another common vulnerability that is the result of lax input validation. Unlike cross-site scripting vulnerabilities that are ultimately directed at your site’s visitors, SQL injection is an attack on the site itself—in particular its database. The goal of SQL injection is to insert arbitrary data, most often a database query, into a string that’s eventually executed by the database. The insidious query may attempt any number of actions, from retrieving alternate data, to modifying or removing information from the database.

TheMole is an automatic SQL Injection exploitation tool. Only by providing a vulnerable URL and a valid string on the site it can detect the injection and exploit it, either by using the union technique or a boolean query based technique.

TheMole Features
 * Support for injections using Mysql, SQL Server, Postgres and Oracle databases.
 * Command line interface. Different commands trigger different actions.
 * Auto-completion for commands, command arguments and database, table and columns names.
 * Support for query filters, in order to bypass certain IPS/IDS rules using generic filters, and the  possibility of creating new ones easily.
 * Developed in python 3.

- How to Change the Network MAC Address on Ubuntu Linux - macchanger

A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used for numerous network technologies. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model.

MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card's read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address. A network node may have multiple NICs and will then have one unique MAC address per NIC.

MACChanger is a GNU/Linux utility for viewing/manipulating the MAC addresses of network interfaces. It can set specific, random, vendor-based (with a 6600+ vendor list), and device-type-based MACs.

- A Fast Web Server Log Analyzer - Visitors

Visitors is a very fast web log analyzer for Linux, Windows, and other Unix-like operating systems. It takes as input a web server log file, and outputs statistics in form of different reports. The design principles are very different compared to other software of the same type:

* Designed to be executed by the command line, output html and text reports. The text report can be used in pipe to less to check web stats from ssh.
 * Support for real time statistics with the Visitors Stream Mode.
 * To specify the log format is not needed at all. Works out of box with apache and most other web servers with a standard log format.
 * It's a portable C program, can be compiled on many different systems.
 * The produced html report doesn't contain images or external CSS, is self-contained, you can send it by email to users.
 * Visitors is free software (and of course, freeware), under the terms of the GPL license.

Visitors Reports information
Visitors reports contain a number of useful information and statistics:
 * Requested pages.
 * Requested images.
 * Referrers by hits and age.
 * Unique visitors in each day.
 * Page views per visit.
 * Pages accessed by the Google crawler (and the date of google's last access on every page).
 * Percentage of visits originated from Google searches for every day.
 * User's navigation patterns (web trails).
 * Key phrases used in Google searches.

- Hardening Ubuntu Linux using Bastille Linux

The Bastille Hardening program "locks down" an operating system, proactively configuring the system for increased security and decreasing its susceptibility to compromise. Bastille can also assess a system's current state of hardening, granular reporting on each of the security settings with which it works.

Bastille currently supports the Red Hat (Fedora Core, Enterprise, and Numbered/Classic), SUSE, Debian, Gentoo, and Mandrake distributions, along with HP-UX. Bastille's focuses on letting the system's user/administrator choose exactly how to harden the operating system. In its default hardening mode, it interactively asks the user questions, explains the topics of those questions, and builds a policy based on the user's answers. It then applies the policy to the system. In its assessment mode, it builds a report intended to teach the user about available security settings as well as inform the user as to which settings have been tightened.

- Block Brute-Force Attempts on Ubuntu Linux - Fail2Ban

Fail2ban operates by blocking selected IP addresses that may belong to hosts that are trying to breach the system's security. It determines the hosts to be blocked by monitoring log files (e.g. /var/log/pwdfail, /var/log/auth.log, etc.) and bans any host IP that makes too many login attempts or performs any other unwanted action within a time frame defined by the administrator.

Fail2ban is typically set up to unban a blocked host within a certain period, so as to not "lock out" any genuine connections that may have been temporarily misconfigured. However, an unban time of several minutes is usually enough to stop a network connection being flooded by malicious connections, as well as reducing the likelihood of a successful dictionary attack.

Fail2ban can perform multiple actions whenever an abusive IP is detected: update Netfilter/iptables firewall rules, or alternatively TCP Wrapper's hosts.deny table, to reject an abuser's IP address; email notifications; or any user-defined action that can be carried out by a Python script. The standard configuration ships with filters for Apache, Lighttpd, sshd, vsftpd, qmail, Postfix and Courier Mail Server.

- Secure Proxy to Surf the Web Anonymously on Linux - Anon-Proxy

Anon-Proxy contains the JAP client which acts as a local proxy between your browser and the insecure Internet. All requests for web pages are handled by JAP and are encrypted several times. The encrypted messages are sent through a chain of intermediate servers (named Mixes) to the final destination on the Internet.

Multiple layers of encryption protect all messages. A Mix collects messages in a batch, totally changes their appearance (removes one layer of encryption) and forwards them all at the same time, but in a different order. An adversary may observe all communication links, however he cannot determine a relation between incoming and outgoing packets. A surfer remains anonymous within the group of all users of the service.

Demonstrably, the Anon-Proxy protects your privacy as long as the Mix works correctly. Each message passes through several Mixes and the entire chain of Mixes has to be corrupt to successfully observe the user's activities. The chaining effectively prevents single Mixes from observing. This is the meaning of strong anonymity: Even the anonymity service itself cannot spy on its users.

- Metadata Injector for FLV Video Files - Flvmeta

The information that composes an FLV file is the data, and the metadata is information about that video. The length of the video (duration), the number of frames per second that the video displays (frame rate), and the number of kilobytes of data transferred per second when the video plays (video and audio data rates, where applicable) are all examples of video metadata. Additionally, the codec used to encode the video is also available.

Importance of FLV Metadata
Most FLV players read the metadata first to know the duration of the video file. After that it initializes or synchronizes the video file with its timeline or seekbar. If there is no metadata the seekbar will not progress with the video. Secondly, for more intelligent FLV players that serve the video or rather buffer the video dynamically, depending on the user’s internet speed, the FLV players read the FLV video bitrate from the FLV metadata and then sets the buffer accordingly.

- Flash Video (flv) Metadata / Cue Point Injector and Cutting Tool - Flvtool2

FLVTool2 calculates various meta data and inserts a onMetaData tag in the video. It cuts FLV files and adds cue Points (onCuePoint). A debug command shows the inside of a FLV file and the print command gives meta data information in XML or YAML format.

What is CuePoint:
A cue point is a point at which the video player dispatches a cuePoint event while a video file plays. You can add cue points to an FLV file at times that you want an action to occur for another element on the web page. Cue points allow you to receive control in your ActionScript code to synchronize points in your FLV file with other actions on the web page. 

FLVTool2 Features
 * Batch processing
 * Directory recursion
 * Command chaining
 * FLV files cutting
 * onCuePoint tag insertation via XML file
 * Custom onMetaData key-value pairs
 * Meta data printout in XML or YAML
 * Simulation mode
 * Runs on Windows, Linux and Mac OSX
 * Ideal for serverside automatic meta data injection

- Personal Full Text Search UI Application - Recoll

Recoll is a full text search application. Full text search applications let you find your data by content rather than by external attributes (like a file name). More specifically, they will let you specify words (terms) that should or should not appear in the text you are looking for, and return a list of matching documents, ordered so that the most relevant documents will appear first.

You do not need to remember in what file or email message you stored a given piece of information. You just ask for related terms, and Recoll will return a list of documents where those terms are prominent, in a similar way to Internet search engines.

Recoll uses the Xapian information retrieval library as its storage and retrieval engine. Xapian is a very mature package using a sophisticated probabilistic ranking model. Recoll provides the mechanisms and interface to get data into and out of the system.

- How to Install / Configure PostgreSQL Under Ubuntu Linux

PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) available for many platforms including Linux, FreeBSD, Solaris, MS Windows and Mac OS X. It is released under the PostgreSQL License, which is an MIT-style license, and is thus free and open source software. PostgreSQL is developed by the PostgreSQL Global Development Group, consisting of a handful of community volunteers employed and supervised by companies such as Red Hat.

It implements the majority of the SQL:2008 standard, is ACID-compliant, is fully transactional (including all DDL statements), has extensible data types, operators, and indexes, and has a large number of extensions written by third parties.

PostgreSQL Installation:
Open the terminal and type following command to install postgresql

- UI Application for Alternatives Configuration - Galternatives

update-alternatives creates, removes, maintains and  displays  information  about  the symbolic links comprising the Debian/Ubuntu alternatives system.

It is possible for several programs  fulfilling  the  same  or  similar functions  to  be  installed  on a single system at the same time.  For example, many systems have several  text  editors  installed  at  once. This gives choice to the users of a system, allowing each to use a different editor, if desired, but makes it difficult for a program to make a  good  choice for an editor to invoke if the user has not specified a particular preference.

Debian's alternatives system aims to solve  this  problem. A  generic name in the filesystem is shared by all files providing interchangeable functionality. The alternatives system and  the  system  administrator together  determine  which  actual  file  is referenced by this generic name. 

For example, if the browsers like Chrome, Firefox and Opera are installed on the system, the alternatives system will cause the generic name /usr/bin/x-www-browser to refer to /usr/bin/google-chrome by  default.  The  system administrator  can  override  this and cause it to refer to /usr/bin/firefox instead, and the alternatives system will not alter this setting  until explicitly requested to do so.

- Convert HTML pages to WML (WAP) or i-mode pages for Mobile - Html2Wml

Html2Wml converts HTML pages to WML decks, suitable for being viewed on a Wap device. The program can be launched from a shell to statically convert a set of pages, or as a CGI to convert a particular (potentially dynamic) HTML resource.

Although the result is not guarantied to be valid WML, it should be the case for most pages. Good HTML pages will most probably produce valid WML decks. To check and correct your pages, you can use W3C's software: the *HTML Validator*, available online at http://validator.w3.org and *HTML Tidy*, written by Dave Raggett.

Html2Wml provides the following features:
 * translation of the links
 * limitation of the cards size by splitting the result into several cards
 * inclusion of files (similar to the SSI)
 * compilation of the result (using the WML Tools, see the section on "LINKS")
 * a debug mode to check the result using validation functions
