Free flavor of the week software for linux

John the Ripper is a fast password cracker, currently available for many flavors of Unix (11 are officially supported, not counting different architectures), DOS, Win32, BeOS, and OpenVMS.
It supports several crypt(3) password hash types which are most commonly found on various Unix flavors, as well as Kerberos AFS and Windows NT/2000/XP LM hashes.
Several other hash types are added with contributed patches.
Enhancements:
- Bitslice DES code for x86-64 that makes use of the 64-bit mode extended SSE2 with 16 XMM registers has been added for better performance at DES-based crypt(3) hashes with x86-64 builds on AMD processors.
- A new make target for FreeBSD/x86-64 has been added.

Pivot is a web-based tool to help you maintain dynamic sites, like weblogs or online journals.

Pivot Weblog is written in PHP, and does not require additional libraries or databases to function.

Pivot is easy to setup, easier to maintain, and even easier to work with. It is template based and fully adaptable to your wishes. Language packs are supported.

It is easy to upload and include pictures with your log entries. There is a comment system that remembers your visitors.

Automagic archiving can be done by week or month. Stylesheets are used extensively. All data is stored in flat files, so no databases are required.

Slicetime is a program that helps you track time you spend on projects. Slicetime is designed to make it easy to switch between different projects, the main window is in the shape of vertical sidebar that makes it convenient to keep it always visible on the side of the screen. In short, continuous tracking of time taken on projects is made as effortless as possible.
The purpose of the program is to make you aware of which tasks take more time, and which take less; it can also be used to keep track and charge time if youre working for someone on hourly basis. The advantage of the program is that it lets you switch back and forth very easily, letting you keep a very accurate account of how much a task took even if you have to stop it frequently and work on something else.
The results can be very surprising, something may feel like it took only a few minutes whereas it took almost an hour in real time; the reverse is sometimes true although not as often.
Slicetime main window is a vertical bar with a row of buttons, each button representing a project. When the button is pressed in, the project is active, the rest of projects are inactive. Each project button shows the time taken on the project today. At 12 oclock the daily time is reset and new days count is started.
Time is kept for current day, week, month and total. Example: I may have a slicetime project that has 3:59 time today, 8:00 this week (including today), 17:00 this month (including this week) and 125:00 total time, which may have been accumulated over years.
Slicetime makes it easy to change project time for current day if you forgot to check in or check out. Menu command (add or subtract project time) will add or subtract the time for today. Another command will set all times for total, month, week and day.
Slicetime as of now has two report options, it can report by time taken for each project on a daily, weekly, montly and total basis and the same by percentage. For example, it will show that today project A was 60%, project B - 30% and C - 10%, and will do the same for current week, month and total.
Note that Slicetime does not keep separate time accounting from previous week, month, day, etc. It will not tell you that you spend 5 hours last saturday. It will only tell you total time, time taken on current month, week and day; but it makes perfect sense to keep this data as well, and I will almost certainly add it.
Functionality:
- Add project
- Remove project (deletes all data and button, irrecoverable, use sparingly!)
- Report by time
- Report by percentage
- Set project time
- Add or subtract project time
Version restrictions:
- Number of project buttons is effectively limited by vertical size of screen. On a common 1024 res, you can fit in around 42 projects, which should be enough for anyone, but I will add an option of hiding projects from main window if requested.
- Latest version not tested in Unix, but will most likely work. I will test it soon & fix if needed.
- Could keep time for each past day, week, month, year. Most likely will be added eventually.
Enhancements:
- Several bugs were fixed.
- The interface was changed to be more user friendly.
- Autosave functionality was added to make up for some stability problems on WinXP.

The Data Mine is a search engine designed to give users an unusually powerful interface. It is designed around human-computer intelligent interaction (making the computer a tool so humans can use their intelligence).

The project divides the screen into two halves: one lets you find all the instances of your querys keywords, and the other lets you look through a highlighted version of the results you choose.

Installation:

Basics

To install, run "./install" and answer the questions provided. This will run a Unix-flavor install-style script and should create a working, out-of-the-box installation when supplied appropriate values.

See USAGE below if are curions about how to use the Data Mine.

Setup and Customization

The Configure link at the bottom of the Data Mine search page provides a menu you can use to customize the data mine.

The main engine is intended for anyone to be able to use; the setup pages are written for techies. If you arent sure what a regular expression is, for instance, ask someone whos more technical.

Security

The present release of the Data Mine has not been closely scrutinized for security, and should be treated as such by security-conscious administrators. If you discover a vulnerability, please contact the author.

You are strongly encouraged to change the password in /usr/share/datamine/password.

The default installation sets /usr/share/datamine and contents to a relatively permissive mode. Administrators are encouraged to set directory and contents to mode 700, owned by the effective user ID that CGI scripts will be running under. This is usually apache or nobody.

Usage:

The Data Mine is designed to be run as a straightforward web application, with much administrative activity performed on-web.

Once it is set up via the Configure link, just explore.

http://[your hostname]/cgi-bin/datamine

(That is the location provided by RPM installation and the default for the provided installer. The provided installer allows you to specify another location; if you specified another location, substitute that for "/cgi-bin/furball".)

ImSafe (Immune Security For your Enterprise) is a host-based intrusion detection tool. After a learning phase, it is able to detect changes in processes behavior, to detect buffer overflows, etc. It is implemented through a device driver (as a kernel patch) for the Linux kernel, but can also be run on other UNIX systems by using a "sensor" built on strace base.
Main features:
- Anomaly detection by analysing audit trails of system calls
- Fast detection of Buffer Overflow Attacks through our call origin heuristic mecanism
- GTK based graphical user interface
- Created for Linux systems but works on almost every UNIX flavor
- Monitor multiple processes of one single application at a time (its enough for testing purposes)
- React in real-time to an attack by executing the script of your choices

stic bundles a few Linux tools which are intended to support the task of collecting an unreasonable amount of pictures (preferrably in JPEG format).
similar
a program for detecting duplicate or very similar images. It maintains a
database of characteristic color samples which it compares with submitted
pictures. similar depends on libjpeg and ImageMagick s convert (on a
modern Linux desktop system these components should already be present).
Storage medium may be a usual filesystem or a MySQL database. There
also is a MySQL UDF extension to compare image samples within SQL queries.
similar contains the communications module described at sagent.
simv
a core program to perform file management tasks on an image collection.
Its main purpose is to coordinate file movements with the content of
similars database. This applies to importing new files which get tested
against the existent collection, as well as to inform similar about moving
and deleting files within the collection.
simv depends on an external image viewer like ImageMagick s display
(should already be present on a modern Linux desktop system) or John
Bradleys xv (quite a fast one).
simv contains the communications module described at sagent.
sagent
a standalone version of the communications module used in simv and
similar. This software receives input from its start terminal and multiple
clients, distributes several types of output back to them, and is also
able to act itself as such a client.
Since communications mainly use TCP/IP there is an encryption layer
(Blowfish with 128 bit keys) which provides user authentication. Any
single activity of such a user may be particularly permitted or denied.
Secure connections should be possible that way as long as one can defend
the keyfiles and programs on client and server host against foreign
access.
Front-end connection software is available in C, Tcl/Tk and PHP3 to build
custom clients. In the most primitive case even telnet can act as a
client.
The standalone program sagent may be used as communications node in a tree
of clients. Another purpose is to be a shell frontend which sends commands
to a server and receives its replies.
snntpbatch
a command line based NNTP (newsgroups) client. It is mainly intended for
automatic download of images by use of a filter language. Nevertheless it
also downloads the message texts and converts them to HTML code which
includes the downloaded images. Also, it is capable of automatically
posting sets of images to the newsgroups.
The tools are designed to be very independent of the system flavor. On an
average Linux desktop there should be no need to update existing system
components. Actually one could use stic without having display equipment for
graphics.
Any program activity which is possible in dialog may also be performed in
batch runs. Therefore the tools are quite suitable for users who like to get
boring tasks automated and manual tasks simplified.
All tools code is open source and distributed under BSD license.

Enhancements:
- The new encrypted protocol version 0.2 is standard now : SHA-1 seal, 256 bit keys, variable chaining initialization vector.
- The protocol of a connection is chosen by the client and may or may not be accepted by the server.
- See sagent command -security options clientprotocol , serverprotocol.
