Free proxy definition software for linux

Proxy Detector is a PHP class that can detect HTTP requests via proxy. This class can detect if a visitor uses a proxy server by scanning the headers returned by the user client.
When the user uses a proxy server, most of the proxy servers alter the header. The header is returned to PHP in the array $_SERVER.
Enhancements:
- This is the first release of the class and implementation example.

Proxy Applet is a GNOME tray applet for changing your network proxy configuration with a single click, in a manner similar to Galeon 1.x.
Galeon used to have a single click Network Proxy selector in their menu, which I used frequently. In a discussion with Epiphany developers about this same functionality (using GConf) they argued that you could already move the Proxy Network capplet to your taskbar.
But that doesnt offer all the functionality Im looking for. What I think would be neat is:
- An applet that gives you a list of preset configurations upon a single click.
- Each configuration is called a location and could either mean:
No proxy
Manually configured proxy
Proxy Auto Configuration (PAC)
A remote URL, eg. http://pac.isp.net/path/file.pac
A local URI, eg. file:///home/user/pacs/location.pac
- When you select another location, the applet should replace your GConf settings accordingly. (GConf key: /system/http_proxy)
- A preferences dialog should allow to manage locations and even test a location (see if proxy works or check PAC syntax ?).
- In a later phase there might even be an automatic selection based on eg. the network-configuration (ip-address, network, gateway, ??). So the applet has to monitor the network configuration for changes.
- When using tsocks or dante lib, we could have a dialog to socksify the complete system. (Add it to /etc/ld.so.preload or run /etc/init.d/tsocks)

phpWebPROXY provides a simple Web proxy written in PHP.

It allows you to run your Web surfing through your own Web server and bypass filters which may be between you and what you want to see.

It supports cookies, and its Web-based location bar lets you move around the Web easily.

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.

Blitzed Open Proxy Monitor or BOPM, is an open source open proxy monitor, designed for use with hybrid-based ircds, although it can be used with slight modification on any server which has the ability to show connects to opers and that supports KLINEs.
BOPM is known to work without modification on the following ircds:
- Bahamut (tested with 1.4.28, 1.4.30)
- Hybrid (tested with 2.8/hybrid-5.3p8, ircd-hybrid-6.3 and ircd-hybrid-7)
- ircd-ratbox (tested with > 2.1.8)
- charybdis (tested with > 2.0.0)
- Unreal (tested with 3.1.2 and 3.2)
- Dancer (tested with 1.0.31)
- TR-IRCD
- IRCu
- Ultimate (tested with UltimateIRCd 2.8.8 and 3.0.0.b3) - please note, earlier versions of Ultimate IRCD are not supported
- LiquidIRCd (tested with 1.0.4)
- InspIRCd (known to work with 1.0 and 1.1 version branches - instructions are given here)
Please note that BOPM will not work with older versions of Unreal without modifying Unreal to send the clients IP address in a connection notice. Patches are also available for download. On the latest versions of Unreal this is no longer needed. Remember for all Unreal versions you must set the perform line correctly (documented in the config file).
How does it work?
When a client connects to the IRC server, BOPM scans the client for open proxies. It then determines whether they are really open by using them to connect back to the server.
How does BOPM improve on first generation scanners (wgmon, tcm, oomon)?
It extends them by adding support for SOCKS4, SOCKS5, WinGate, HTTP proxies, insecure Cisco routers, simultaneous connections, and a more scalable model (written in C). BOPM also has support for a DNS blacklist, similar to MAPS RBL+ or Visi RSL
BOPM is in use without issue on servers receiving over 400 connections per minute during normal real-world operation (as in, regular client load excluding bursts and attacks). That is 7 user connections per second, enough for even the largest of IRC servers.
Additionally, BOPM contains the ability to match hosts against a DNS blacklist such as DroneBL or your own custom list, it can also submit new proxies that are found via email if the list accepts them.
Enhancements:
- This version was fixed to work with GCC 4 and various other cleanups.

The Zaval Proxy Suite is an easy-to-use solution that allows monitoring TCP-based protocols, such as HTTP, NNTP and others. It is extremely useful in software development and can be used as a debug tool. Another area of appliance is multiple connections logging with proxy facilities. As soon as its a pure java solution it can be used almost everywhere.

The Zaval Proxy functions as a proxy and transfers data between the server and the client writing incoming and outgoing traffic into log files. So you can see these raw data as is.

On start the Zaval Proxy Suite goes through configuration file and creates the specified number of proxy servers and the shutdown server.

"Proxy server" is a server socket listening on the specified port. When the client is connected proxy connects to the target server and transfers data between them logging entire traffic. On each connection 2 files are created - xxx-input (request data from the client) and xxx-output (response data from the server). The "xxx" means here the sequential number of the connection for the proxy server. The traffic is logged into the separate directory for each proxy.

Shutdown server is needed to close all open connections correctly and close the program.

So, in the particular case you should specify address of proxy server in client application (web browser, for example) and address of the target server in the proxy configuration file. You can create any number of proxy servers that run at the same time, however, they should use different port numbers.

FSP Proxy provides a proxy server for FSP to HTTP protocol translation.
FSP Proxy is a proxy server for FSP to HTTP/1.0 protocol translation. It also accepts gopher:// URLs as an alias for fsp://. You can set it up as a gopher proxy in your browser, and easily access FSP sites.
This proxy supports HTTP/1.1 on output side and FSP v2 on input side. Subrange byte requests are supported, resume works nicely. Simply FSP v2 over HTTP/1.1. This proxy do not caches anything.
This proxy makes playing with FSP very easy for newcommers, there is no need to learn classic fsp command line interface tools. Everybody who can handle downloads in browser, can now play with FSP sites available through Internet.
