QoS Connection Tuning HOWTO is a document which explains how to tune network connection performance.

This enables you to get the maximum benefit out of your connection without lag and loss.

JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apples OS X.

Jack audio connection kit can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin").

JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation.

Gnome Remote Connection Manager is a gnome application that stores information
about remote connections.
It gives you a GUI program to launch applications like telnet, shh, or rdesktop. It is highly configurable as to what type of applications it launches, so you are not limited to the three listed, for example I never thought of using it for ftp, but it would be easy to setup.
GRCM uses gconf to store information about connections.
Enhancements:
- Added some missing icons.
- Fixed a callback in the Connections Dialog that made the default arguments from the connection appear when selected.

dslKonnector is a Kommander script to start, stop, restart DSL connection (ppp over ethernet), using tools "pon dsl-provider" and “poff dsl-provider".

To use it you will need to have superuser privileges. dslKonnector does not configure dsl connection, so you will have to setup it using tool "pppoeconf".

I created this script because there was no graphical way to control dsl connection in Kubuntu Dapper, and I needed it sometimes, since some dynamic IPs my wife would receive from our ISP would be blocked from my IRC network.

Would that kind of app be needed? If so, how do I improve it? Suggestions welcome!

ProxyChain generates a chain of proxies which can give you greater anonymity. ProxyChain project uses HTTP/1.x proxies with CONNECT method supported.
The program supports a listen mode, which will communicate a local port through the chain, creating a brand new chain per connection.
Enhancements:
- A very confortable listen mode was added, which stays in the background (or not with the -D option) and will create a new chain with each incoming connection.
- Detection was added for unhealthy scenarios where the connection you are trying is unsafe or senseless.
- A couple of bugs with servers prematuraly closing the connection were fixed.

NetworkManager program is a network connection manager for most RPM and Debian-based distros.

Supports Ethernet, WiFi, VPN connections.

Networking on Linux should not suck like it does right now for the desktop user. The desktop user should never need to use the command-line to configure their network; it should "Just Work" as automatically as possible and intrude as little as possible into the users workflow.

The computer should use the wired network connection when its plugged in, but automatically switch to a wireless connection when the user unplugs it and walks away from the desk.

Likewise, when the user plugs the computer back in, the computer should switch back to the wired connection. The user should, most times, not even notice that their connection has has been managed for them; they should simply see uninterrupted network connectivity.

Flexible, Extendable, and Open

The most important pieces of NetworkManager are desktop-environment and distribution agnostic, functioning just as well in Gnome, KDE, Xfce, etc. across distributions like Fedora Core, Debian, Gentoo, and Slackware.

And since the NetworkManager components communicate with each other using dbus, its easy to rip out and replace any of the User Interface pieces at any time.

Application Integration

Using the awesome power and flexibility of dbus and hal, NetworkManager provides facilities for other desktop applications like browsers and email clients to be aware of the networks state and adjust their operation accordingly for features like offline operation.
