Free 7.2 software for linux

Streamline is a high-speed networking subsystem for commodity operating systems. It increases performance by moving processing tasks to the fastest location. Streamline supports in-kernel execution, but also dedicated hardware (NICs) and even remote machines. An implementation of Streamline for Linux 2.6.13 and higher is made publicly available.
The goal of Streamline is to make fast network processing viable for common tasks. Many advanced processing schemes so far fail to make it into OSes, because they are difficult to combine with the socket(..) API or only applicable in a few situations. Our goal is to integrate known as well as develop new methods that replace sockets(..). without burdening application developers and end-users. Streamline achieves this by constructing a tailored dataplane for each application at runtime from an extensible set of functions.
Applications request information streams by specifying a series of abstract functions that need to be performed on incoming data (e.g., select tcp packets for port 80, reassemble into a stream, filter out known attacks). At runtime, streamline searches for implementations of these functions. These can be found in the kernel, in the application library, or in dedicated hardware such as programmable network cards or asymmetric multicores. When all functions are found, interconnecting datapaths are setup. Paths may need to cross the PCI bus, userspace/kernelspace barrier or even LANs. Optimisation of these paths is one of the factors that contributes to Streamlines performance.
The base system comes bundled with functions for pattern matching (Aho Corasick, RegEx), accounting, filtering (among others BPF), stream reassembly, rewriting, inspection, and more. Obvious uses are intrusion detection, network address translation, media streaming and realtime (pre)processing of scientific data.
Enhancements:
- This is mostly a stabilization release, which adds support for Linux kernels up to 2.6.22 and Fedora Core installations.
- The only truly new feature is a virtual filesystem interface (like sysfs) to streamline.
- With this "netmonfs" you can inspect live datastreams as if youre reading local files.
- Setting up streams and filters is easily accomplished through mkdir, open, and other well-known tools.
- Note that netmonfs is still beta quality software.

TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.
The distribution comes with a number of tutorial and example circuits which can be loaded through the "Help" menu. The example circuits include a simple CPU, programmed to run the Animals game. TkGate is free software provided with source code under the Gnu Public License.
Main features:
Graphical circuit design
- Hierarchical design through user defined modules.
- Easy to use point-and-click user interface.
- Create hyperlinks to move about in circuit or load other files.
- Multi-lingual interface (Catalan, English, French, German, Japanese, Spanish, Welsh)
- Verilog-like save file format.
Logic simulation
- Control through the GUI or through script files.
- Suitable for simulation at transistor, gate or register transfer level.
- Six valued logic model including 0, 1, floating, unknown, "low" and "high".
- Support for custom delay models.
- Graphical display of simulation results.
- Breakpoints, single-step and clock-step simulator control.
- Static critical path analysis.
Primitive circuit elements include:
- Basic gates (AND, OR, etc.)
- Switch-level NMOS and PMOS transistors
- Tristate buffers
- Alu components (Adders, shifters, multipliers)
- Memory elements (Registers, RAMs, ROMs)
- An interactive "tty" element allows design of circuits that can interact with the user.
Support tools include a microcode/macrocode compiler to assist in creating large projects such as microprocessor designs.

ockso is a free, open-source, personal music server for everyone! Its designed to be as simple as possible so that anyone with a mouse and some mp3s can get their friends listening to their music across the internet in minutes!
Main features:
- Simple setup (up and running in seconds)
- Supports MP3s
- Easy web-interface for your friends, and a GUI for you!
- Statistics like most played, recently popular, etc...
- Drag and drop playlist creation
Enhancements:
- This release has a console mode so it can be installed, administrated, and run on servers without a GUI.
- Many bugs have been fixed after a lot of missing unit testing was implemented.

This is proxytunnel, a program that connects stdin and stdout to an origin server through HTTPS proxy.
Short guide to installing proxytunnel
On most modern unix systems, use the normal Makefile
On MAC OS X, use Makefile.darwin
If you dont have gnu-getopts, use Makefile.no-gnu-getopts
If you want to enable setproctitle functionality, add a CFLAGS define -DSETPROCTITLE (uncomment sample in Makefile)
Run make and optionally make install.
If you manually want to install, copy proxytunnel to /usr/local/bin and optionally the manual-page from the debian-subdirectory to your manpath.
Enhancements:
- Fixed buffer/malloc issue
- Clean-up usage info/help text
- Remove spurious syslog
- Added build-number to versionstring

The SME Server server and gateway is free software (also referred to as open-source software) and is freely available for anyone to download.
This software is brought to you by the community and contribs.org. Many individuals and organizations (both commercial and non-profit) use the SME Server as their primary network server and gateway.
We would like to remind you that the SME Server software is licensed under the General Public License (GPL). This means that if you alter the software and distribute the altered version, you must make the source code for your altered version freely available.
The GPL is a large part of why free software has made such an impact on the commercial scene. By restricting anyone from making proprietary modifications, the GPL ensures that improvements find their way back to the original code base, thereby creating an explosive rate of technical advance.
The difference between traditional development and GPL development is the difference between a light bulb - where output is radiated in many directions - and a laser - where output is reflected back in a coherent way to produce a greater, more focused result.
Its main design focus is simple, centralized configuration, along with security and ease of installation.
Enhancements:
- This release is based on CentOS 4.5 and all packages have been updated to the latest releases. This release contains many new features, all released updates for SME Server 7.1 and fixes for many reported problems. Upgrades will be available by CD, the Software Installer and command line. All users should upgrade to this release.
