CFL is a C library of useful functions that simplify systems software development on System V UNIX.
The library includes routines for memory management, string parsing, filesystem traversal, subprocess execution, I/O, as well as implementations of common data structures such as linked lists, hash tables, stacks, and queues.
CFL library also includes a high-level interface to Berkeley sockets, and an implementation of a scheduler which has functionality very similar to that of the cron daemon.
This package may not compile with older versions of gcc. Version 3.3
or later is highly recommended.
Installation:
The simplest way to compile this package is:
1. `cd to the directory containing the packages source code and type `./configure to configure the package for your system. If youre using `csh on an old version of System V, you might need to type sh ./configure instead to prevent `csh from trying to execute `configure itself.
Running `configure takes awhile. While running, it prints some messages telling which features it is checking for.
2. Type `make to compile the package.
3. Optionally, type `make check to run any self-tests that come with the package.
4. Type `make install to install the programs and any data files and documentation.
5. You can remove the program binaries and object files from the source code directory by typing `make clean. To also remove the files that `configure created (so you can compile the package for a different kind of computer), type `make distclean. There is also a `make maintainer-clean target, but that is intended mainly for the packages developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution.
Enhancements:
- Two bugs were fixed.

KAON project consists of an ontology management infrastructure targeted at business applications.

It includes a comprehensive tool suite allowing easy ontology creation and management and provides a framework for building ontology-based applications.

An important focus of KAON is scalable and efficient reasoning with ontologies.

Persistence mechanisms of KAON are based on relational databases.

Zope is an open source web application server primarily written in the Python programming language. Zope features a transactional object database which can store not only content and custom data, but also dynamic HTML templates, scripts, a search engine, and relational database (RDBMS) connections and code.

It features a strong through-the-web development model, allowing you to update your web site from anywhere in the world. To allow for this, Zope also features a tightly integrated security model. Built around the concept of "safe delegation of control", Zopes security architecture also allows you to turn control over parts of a web site to other organizations or individuals.

The transactional model applies not only to Zopes object database, but to many relational database connectors as well, allowing for strong data integrity. This transaction model happens automatically, ensuring that all data is successfully stored in connected data sources by the time a response is returned to a web browser or other client.

There are numerous products (plug-in Zope components) available for download to extend the basic set of site building tools. These products include new content objects; relational database and other external data source connectors; advanced content management tools; and full applications for e-commerce, content and document management, or bug and issue tracking.

Zope includes its own HTTP, FTP, WebDAV, and XML-RPC serving capabilities, but can also be used with the Apache or other web servers.

Zope can help you create dynamic web applications such as portal and intranet sites quickly.
Zope comes with everything you need including support for membership, search, and news.

Nagios (formerly Netsaint) is a daemon written in C that is designed to monitor networked hosts and services.
Nagios project has the ability to notify contacts (via email, pager or other methods) when problems arise and are resolved. Host and service checks are performed by external "plugins", making it easy to write custom checks in your language of choice.
Several CGIs are included in order to allow you to view the current and historical status via a Web browser, and a WAP interface is also provided to allow you to acknowlege problems and disable notifications from an internet-ready cellphone.
Main features:
- Monitoring of network services (SMTP, POP3, HTTP, NNTP, PING, etc.)
- Monitoring of host resources (processor load, disk and memory usage, running processes, log files, etc.)
- Monitoring of environmental factors such as temperature
- Simple plugin design that allows users to easily develop their own host and service checks
- Ability to define network host hierarchy, allowing detection of and distinction between hosts that are down and those that are unreachable
- Contact notifications when service or host problems occur and get resolved (via email, pager, or other user-defined method)
- Optional escalation of host and service notifications to different contact groups
- Ability to define event handlers to be run during service or host events for proactive problem resolution
- Support for implementing redundant and distributed monitoring servers
- External command interface that allows on-the-fly modifications to be made to the monitoring and notification behavior through the use of event handlers, the web interface, and third-party applications
- Retention of host and service status across program restarts
- Scheduled downtime for suppressing host and service notifications during periods of planned outages
- Ability to acknowledge problems via the web interface
- Web interface for viewing current network status, notification and problem history, log file, etc.
- Simple authorization scheme that allows you restrict what users can see and do from the web interface
Enhancements:
- Fix for incorrect performance data file write/append mode options
- Fix for current status of hosts with no host check command defined
- SIGSEGV signals should now be logged again (broken in 2.8)
- Configure script fix for no mail program found/installed on system
- Configure script option bug fixes for cygwin and embedded perl
- Command definitions and host/service plugin perfdata with HTML should now be escaped in CGIs
- Patch for incorrect time down percentage in availability CGI
- Updated init script to fix a race condition during restarts

Afick is a security tool, very close from the well known tripwire. It allows to monitor the changes on your files systems, and so can detect intrusions.

Afick is designed to be quick and portable.

Functionnalities:

portable without any change to all common operating systems (windows, unix ...)
easy install : no need to compile or to install many others tools
fast
display new/deleted/modified files
display dangling links
may be used by any user
any number of base and config
config file with exceptions and jokers
configuration file syntaxe close from aides one
command line is perfect on unix, but windows users prefer graphical interfaces, so I add a Tk interface

J2SSH provides a fully-featured Java SSH version 2 API implementation.
J2SSH is an object-orientated Java implementation of the SSH version 2 protocol. It provides a rich, powerful, and extensible SSH API that enables developers to gain access to SSH servers and to develop entire SSH client/server frameworks.
The API library provides a fully-featured SSH2 implementation specifically designed for cross-platform development. Higher level components, representing both the standard SSH client and SSH servers, are provided which implement the protocol specification for user sessions and port forwarding.
The specification currently supports public key and password authentication and a full implementation of the SFTP protocol.
Enhancements:
- This release fixes several bugs which have been pending for years.
- These include character encoding problems in sftp and problems with the rekeying code.
- This release is also the first modified release which is only available under the GPL.
