Free switch software for linux

kproxyswitch is a simple bash script, which makes setting the proxy server easier. The setting applies to Konqueror and all other applications that use the global proxy setting.
If you have to change proxies from time to time - or switch the proxy off and on again.
Youll like the possibilty to bind this script to a keyboard/menu/... shortcut and thus be able to switch the proxy faster than going through the menus of Konqueror or KDE Control Center.
Enhancements:
- Small changes: added two apps (randr, nspluginviewer) to blacklist, made output more verbose.

pvswitch is a very tiny program which makes it possible to use different program installations on one machine flawlessly.
Its flexibility is intended for people who need to run programs against different interpreter versions.
But it can also be used for different purposes like switching the version of a compiler, text editor, mail reader, browser, whatever.
It is most useful for developers of interpreter based programs which are started via a hash-bang line (#!).
The following example explains the usage for perl programs, but the very same is true for all other interpreter languages.
If you install two or more different perl versions on your machine, you could just call the respective perl binary you want to use..
perl myscript.pl
/path/to/another/perl myscript.pl
This works fine, although it isnt very convenient. However if you are starting your program using the hash-bang line like
#! /usr/bin/perl
and then just start it by
./myscript.pl
you would need to change the file itself to use another perl version. Again it is possible, but not very convenient.
And here comes pvswitch: its purpose is to make such situations convenient. Further it solve some problems which come up if multiple people want to use different perl versions. pvswitch allows even to run one program in two shells with different perl versions.
This is possible because pvswitch uses a environment variable to select the interpreter version to use. This environment variable can be set in different sessions independently.
pvswitch is installed as new program binary (e.g. perl) the old one will be renamed to program.pvswitch.
Now every time you execute a this program (e.g. perl), pvswitch is executed. It doesnt matter how you start the program...
perl myscript.pl
./myscript.pl # if it has a hash-bang #! /usr/bin/perl
for both cases the pvswitch binary will be executed, pvswitch will than check for the environment variable PVSWITCH_PERL_BINARY (if you are running perl), if it is found it tries to find this key in the configuration file pvswitch.conf and execute the program which is configured for the version configured set in the environment variable (e.g. perl.pvswitch).
So it just executes the real program (e.g. perl interpreter). Depending on the environment a different version might be selected.
There are some convenient tools (e.g. perlver, pvconfig) to configure this.
Enhancements:
- Fixed a bug which could cause segmentation violation.

Linux Layer7 Switchings main goal is to provide a performant framework for Layer7 switching. Layer7 switching is driving a low-level engine using networking design to speed-up forwarding of data stream. Implementation in this project is split into a userspace daemon and a low-level kernelspace forwarding engine.
Userspace daemon is responsible for scheduling and switching decisions. Kernelspace forwarding engine is responsible for forwarding stream and using TCP-Splicing scheme.
TCP-Splicing is the postponement of the connection between the client and the server in order to obtain sufficient information to make a routing decision. This project is close to Linux Virtual Server project since lot of discusions on this topics have been made online and offline LVS project.
Why using L7SW ?
This project will provide you a way to switch incoming clients requests using pattern matching. A quick example is to drive a web server farm by locating specific content on dedicated servers (video, audio, images, ...) while virtual server exported to end user is uniq.
Enhancements:
- The kernel module was backported to Linux version 2.4.
- The Linux 2.6 kernel module was extended to support kernel versions lower than 2.6.19.
- libtcpsplice has been extended to export more helpers.
- A locking issue has been fixed while splicing sockets.
- HAProxy has been extended to support tcp_splicing module.

Linux Multilayer Switch is part of a larger project that aims at building a Linux-based Layer 2 and 3 switching appliance.
We hope this will be integrated into the official Linux kernel someday, but first our code must reach maturity and then we must prove the kernel team that its ok.
This is not just a standalone module, but also a bunch of minor patches for the kernel networking code. We had to hook into the packet reception code. Theres also a hook in the socket ioctl code to implement "deviceless" ioctls on sockets.
This subproject also includes a user space tool to manage the various features of the kernel module.
Linux Multilayer Switch implements ethernet layer 2 switching with VLAN (802.1q) support and VLAN virtual interfaces for inter-VLAN routing.
Enhancements:
- This release adds Cisco Discovery Protocol.
- There are bugfixes to the userspace and kernel code.
- This release has been updated to 2.6.17.

Usplash Switcher is a small utility that allows you to easily switch your usplash (boot theme).

It is useful only if you have installed multiple usplash-artwork packages.

SwitchProxy Tool is a Firefox extension which lets you manage and switch between multiple proxy configurations quickly and easily.

You can also use it as an anonymizer to protect your computer from prying eyes.

NOTE: In Firefox you can use the toolbar element to save space

OpenWrt is a Linux distribution made for wireless routers. Instead of trying to cram every possible feature into one firmware, OpenWrt provides only a minimal firmware with support for add-on packages.
For users this means the ability to custom tune features, removing unwanted packages to make room for other packages and for developers this means being able to focus on packages without having to test and release an entire firmware.
Enhancements:
- Countless bugfixes, various security patches, improved Failsafe, faster installation (new firstboot script), a multilingual Web interface (Cesky, Deutsch, Dansk, Eesti, Espanol, Francais, Italiano, Norsk, and Polski), and ethernet switch configuration (/proc/switch).
