Free easy to use tool software for linux

Network Query Tool is a one-stop solution for obtaining information about a domain name or an IP address.
Instead of manually using a variety of shell commands, or visiting numerous websites to investigate a host, just load Network Query Tool in your browser and enter the hostname or IP. NQT does the rest, as is evidenced by this sample output.
Main features:
- Reverse lookup - resolves an IP address to a hostname (if one exists) or vice versa
- DNS query - aka Dig, requires a dig binary on your system
- Whois (WWW) - gets domain registration information. Now supporting just about every known TLD, gTLD, and ccTLD.
- Whois (IP) - gets IP owner information. Supports all IP blocks maintained by ARIN (US), RIPE (Europe), JPNIC (Japan), APNIC (China/Asia-Pacific), BRNIC (Brazil), LACNIC (Latin America), AFRINIC (Africa), and KRNIC (Korea).
- Check port - Determine whether or not a port on the target host is open. Defaults to port 80.
- Ping - performs a 5-packet ping to the target, requires a ping binary.
- Traceroute - performs a traceroute to the target, requires a traceroute binary.

Easy SVN is a subversion browser via the Web. Easy SVN Browser is easy because only a command line svn program and Perl are required to run it; no extra software needs to be installed. After configuring the Perl script as cgi-bin program, SVN repositories can be navigated, and entries viewed for contents, history, and diffs.
Installation:
Follow these steps for a quick installation of web-svn-view:
1. Log in as the user who is running the webserver (e.g., www).
2. As this user, make sure you have read-access on your repository. Issue an svn command to make sure that if necessary, you are prompted for a username and password. Once the viewer is running, logins must take place automatically.
3. Obtain web-svn-view by getting the archive http://public.e-tunity.com/web-svn-view/web-svn-view-latest.tar.gz . Save the archive on your disk as e.g.
/tmp/web-svn-view-latest.tar.gz.
4. Change-dir to a directory where the webserver will run the viewer.
5. Unpack, using tar xzf /tmp/web-svn-view-latest.tar.gz. Note the full paths to the contained directories cgi-bin, css and img. In the following example well assume that the base directory is /Users/e/src/e.
6. Edit cgi-bin/web-svn-view and modify the configuration variables at the top of the file. The variables are documented in the script.
7. Edit the servers configuration file. E.g, for Apache, edit httpd.conf and add the following lines:
ScriptAlias /svnbin /Users/e/src/e/web-svn-view/cgi-bin
Alias /svncss /Users/e/src/e/web-svn-view/css
Alias /svnimg /Users/e/src/e/web-svn-view/img
< Location / >
Order deny,allow
Deny from all
< /Location >
< Location /svnbin >
Order allow,deny
Allow from all
< /Location >
< Location /svncss >
Order allow,deny
Allow from all
< /Location >
< Location /svnimg >
Order allow,deny
Allow from all
< /Location >
You will need to supply the right directories for your system.
8. Restart the webserver.
9. Point your browser to http://yoursite/svnbin/web-svn-view.
Enhancements:
- The configuration settings in cgi-bin/web-svn-view can now be overridden by environment variables.
- That makes it possible to re-use the same SVN browser to view many repositories, based on environment variables passed by the Web server.
- The documentation was updated with an example.

The 3dfx TV Out Tool tries to be the well-known TV Tool for the 3dfx VooDoo3 cards. It might work on other cards based on the bt869 chip, since it uses the bt869 lm_sensors module.

Simply typing make or make all should get you started and create an executable 3dfx_tvtool which you simply run AFTER you loaded the appropiate modules (if you built it into the kernel (which isnt a bad idea if you use your tv-out a whole lot) then you dont have to load the modules again). ALSO!! Patch your lm_sensors. In the extra dir I included 2 patches for lm_sensors package, youll need those patched or you wont get luma (brightness) and chroma (color) control at all. (The buttons will simply dissapear) If you have a rescent CVS version it MIGHT be in there allready. Just load the modules and see if there exists a luma and a chroma entry in /proc.


Colorbars On/Off: Enables/Disables the colorbars. TV Out: Enabled/disabled Enables/disables the TV-out function. TSC/PAL: put the system on NSTC/PAL mode.
Re-apply: update the kernel with your settings in case you did it too fast. Save: Saves your current kernel settings (all of them) to the default save file. Load: Loades your default file and applies its settings to the kernel. Quit: Quits the application.

Bugreports should go to oliver@are-b.org aswell as any other feedback. Oh one more thing, if you like this program, contributions can be sent to me aswell.

Thanks go out to all members of the Collective, but mostly mrfloppy, for beeing a good friend, phirox for helping me with my basic programming skill and last but not least mastex and thehatter wassup dudes.

The EDDIE Tool is a system monitoring, security and performance analysis agent developed entirely in Python. It runs standalone on a system and performs checks and other actions as defined by an extensible configuration.
The EDDIE Tool can perform all basic system monitoring checks, such as: filesystem; processes; system load; and network configuration.
It can also perform such network monitoring tasks as: ping checks; HTTP checks; POP3 tests; SNMP queries; RADIUS authentication tests; and customized TCP port checks.
Finally, a few checks lend themselves to security monitoring: watching files for changes; and scanning logfiles.
The EDDIE Tool can also send any collected statistic to RRD files to be displayed graphically by any standard RRD tool.
No need to run multiple monitoring and data collection agents. Monitoring rules are just like Python expressions and can be as simple or as complex as needed. Advanced alert control functionality such as exponential back-off and dependencies are also standard.
Enhancements:
- Support for two new platforms: FreeBSD and Microsoft Windows. Solaris 10 support.
- Better support for Linux kernel 2.6.
- SMTP response time monitoring.
- The FILE directive can show diffs when monitored files are modified.
- Disk/filesystem throughput measuring on Solaris.
- Many more enhancements and bugfixes.

Sudoku Tool is a sudoku game that helps you to solve sudoku puzzles. Sudoku Tool can generate puzzles randomly or puzzles can be entered manually.

Some of the features include random puzzle generation, pencil marks, and the ability to save games.

To have a game randomly generated for you, click the Setup New Game button. A new window pops up asking you to select either "Manual" or "Random". Select "random" and a new game will appear.

To build, use:

make -f Makefile.[system]

KJam is a build tool like make. It uses a syntax similar to Jam, with more powerful features than the original Jam.
It has built-in very fast dependency scanning, per-target viewpathing, and C-like control flow. It is optimized for multi-processor machines. It can accelerate building by launching build actions on a distributed peer to peer network of build servers.
KJam Build Tool is designed to support large projects with thousands of targets, or projects requiring building on many target architectures.
KJam is designed to be:
Unintrusive and clean KJam is small. It has negligible CPU overhead, and it doesnt create or leave behind temporary files.
Scalable KJam is able to build large projects spread across many directories in a single pass and can manage and distribute build steps to multiple processors on one or more networked machines.
Highly portable KJam currently runs only on Windows, but it is designed to be easily portable. Ports to Linux and OSX are planned.
Multiplatform Platform independent rules and platform specific actions can be defined separately from dependency rules.
Customizable Developers can enhance and extend KJam by creating user defined rules to utilize other built-in directives.
Language KJam includes flow-control statements, variables, and a few other features of general purpose languages.
Automatic Dependencies KJam computes dependencies for its targets during building. There is no need for a separate off-line make depend step.
Enhancements:
- A new "immediate" action modifier keyword was added, which causes actions to be run as soon as they are parsed, instead of during the command phase.
- Output formatting was improved.
- Several bugs were fixed.

Audio Tag Tool is a program to manage the information fields in MP3 and Ogg Vorbis files, commonly called tags. It is available under the GNU General Public Licence (GPL).
Please send me any comments or bugs you find (email at the bottom)
Tag Tool can be used to edit tags one by one, but the most useful features are the ability to easily tag or rename hundreds of files at once, in any desired format.
The interface is arranged into two sections, with the list of available files on the left and a set of tabs on the right.
Each tab corresponds to one of the main operations Audio Tag Tool can do:
Tag Editor
- Lets you edit the tags individually.
Tag Multiple Files
- Here you can set the tags of multiple files at once. The tag fields can be set to a fixed value, filled in automatically from the files name, or left alone.
Clear Tags
- Allows you to remove the tags from multiple files at once. For MP3 files it lets you choose to remove only ID3v1 or ID3v2 tags.
Move/Rename Multiple Files
- Here you can rename multiple files at once and/or organize them into directories. File names can be based on the contents of the tag.
Create Playlists
- Generates playlists. Playlists can be sorted by file name or by any tag field.
