Free extract data from website software for linux

Check Website is a performance monitoring and uptime notification tool. Check Website will check if a Website is up, and check the response time of the site.
The administrator can then choose to receive an email notification if the site is down, or if the site response time is too slow. All results are also written to a daily log file.
Enhancements:
- This release fixes some small bugs that caused hang ups in the program when checking Web sites.

libextractor is a library that is used to extract meta-data from files of arbitrary type. It is designed to use helper-libraries to perform the actual extraction, and to be trivially extendable by linking against external extractors for additional file types. libextractor is part of the GNU project. Our official GNU website can be found at http://www.gnu.org/software/libextractor/. libextractor can be downloaded from this site or the GNU mirrors.
The goal is to provide developers of file-sharing networks or WWW-indexing bots with a universal library to obtain simple keywords to match against queries. libextractor contains a shell-command "extract" that, similar to the well-known "file" command, can extract meta-data from a file an print the results to stdout.
Currently, libextractor supports the following formats: HTML, PDF, PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI, MAN, MP3 (ID3v1 and ID3v2), OGG, WAV, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), ZIP, ELF, REAL, RIFF (AVI), MPEG, QT and ASF.
Also, various additional MIME types are detected.
libextractor is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
Enhancements:
- This release fixes various build problems and a crash with recent versions of libgsf.
vAn incomplete manual was added.

wavextract is a program for extracting embedded audio data from JPEG images. wavextract project is useful if you have a digital camera that can record audio notes and embed them in photos (e.g. HP, Kodak, Fujifilm, Canon, etc.)

Wavextract is written in Python and is tested on Linux (but it should probably
work also on other operating systems).

You must have Python 2.4 (maybe it will work also with Python 2.3, but I didnt
test it) and Python Imaging Library (PIL) installed.

DOG Data Organizer provides a bookmark organizer for various bookmark types.

DOG is a personal knowledge manager based on topic maps. It currently specializes in managing bookmarks.

It imports and exports Netscape, Mozilla, and KDE2 (XBEL) bookmark files, and it imports KDE1 bookmarks and Windows IE Favorites.

The layer extract plug-in is a Gimp plug-in that creates a new image/film by periodically extracting layers from another image.

It takes one interval (number of sequent layers) every period. The number of periods can be limited.

Joshs Website Framework is a CMS framework for PHP Web developers. Joshs Website Framework consists of various subcomponents you can extract and use individually. SaxInterface provides an OO wrapper for SAX XML parsing.

The Auth Engine provides both level-based permissions (e.g., must be level 100 to access this page) and name-based permissions (e.g., must be in "editor" group to access this page).

Utilities include Mutex and SharedData classes (for interprocess communication), site-wide custom error handling, and the ability to take a site offline for maintenance.

THC-ManipulateData can search data on a harddisk/partition/file, extract the part you are interested in, and write it back after you modified it.
Useful to find and modify really all unencrypted Logfiles on a system. Does everything in RAW mode, and hence does not tamper a/m/ctimes.
It comes with 4 tools:
Syntax of search_data: ./search_data [-i] [-d] blockdevice searchstring
-i - the only parameter which is optional. This does the
search case insensitive.
-d - dump the found occasions in hex
blockdevice - a blockdevice you want to search for data. It need
not to be a blockdevice, it can be anything, but normaly
you use it on these.
searchstring - a string you want to search for
The blockdevice is searched for the occurance of searchstring, which are printed with location when found.
Example: ./search_data -i /dev/hda3 "connect from 10.0.0.1"
Output looks like:
found at 234600: connect from 10.0.0.1/unresolved (UNKNOWN)
Syntax of read_data: ./read_data blockdevice start_address no_of_bytes
blockdevice - a blockdevice you want to get your data from. It need not to be a blockdevice, it can be anything, but normaly you use it on these.
start_address - from which offset of the blockdevice you want to extract data from
no_of_bytes - how many bytes of data starting at the start_address you want to extract in a file.
The output filename is always START_ADDRESS.NO_OF_BYTES
Example: ./read_data /dev/hda3 234653 1024
writes 1024 bytes of data from /dev/hda3 starting from offset 234653 to the file "234653.1024"
Syntax of write_data: ./write_data blockdevice filename
blockdevice - a blockdevice you want to write your data to. It need not to be a blockdevice, it can be anything, but normaly you use it on these.
filename - the data you want to write to the blockdevice. For error protection, the location where it is put it gathered from the filename - as you can see above from read_data. If you modified the data extracted with read_data into the file, it may not have a different size than defined in the filename! The data in filename is written to the blockdevice
Example: ./write_data /dev/hda3 234653.1024
writes 1024 bytes of data to /dev/hda3 starting at offset 234653 with the
data read from the file "234653.1024"
Syntax of replace_data: ./replace_data [-i] blockdevice searchstring replacestring
-i - the only parameter which is optional. This does the search case insensitive.
blockdevice - a blockdevice you want to search for data. It need not to be a blockdevice, it can be anything, but normaly you use it on these.
searchstring - a string you want to search for
replacestring - the string you want to replace the found entries with
The blockdevice is searched for the occurance of searchstring, and is then replaced.
Example: ./replace_data -i /dev/hda3 "connect from 1.0.0.1" "Remap table failure "
Output looks like:
found at 234600 - replaced
Enhancements:
- fixed a bug in read/write_data, seeks over 2gb now succeed
- added -d for hexdump display of occasions found in search_data
