Free proxies software for linux

GNU Proxyknife (formerly known as phc or proxy hunter customed) is a program to validate free proxies for LAN users to reach the Internet by bypassing ISP proxies with strict limits. GNU Proxyknife can be customized to change headers (such as User_Agent) in test requests sent to free proxies.
You can also customize it with your own checksite, checksite port, or checksite key, switch between the CONNECT and GET method, etc., to test and filter free proxies. It can be used to validate free socks5 proxies with a connect command, socks4 proxies with a connect command or free HTTP proxies with a GET or CONNECT method. It can validate free proxies with a TCP tunnel.
Enhancements:
- Myproxy can be a SOCKS4 tunnel.
- This release adds an option "-C", keyword "checkreqin" to enable customizable requests.
- It is possible to implement new protocols (e.g. search MSN proxy).
- Checksite is supported in other protocols (such as ftp://) for HTTP proxies with the GET method.
- This release can be invoked without a startup file.
- Configuring and invoking is simple.
- The output format has been reordered.
- The record of the final request is added to the output.
- The manual has been rewritten.
- Some advanced usages are provided.
- The Chinese translation has been updated.
- Man is integrated into proxyknife.texi.
- Some memory bugs have been fixed.

IOC::Proxy::Interfaces is a IOC::Proxy subclasss to proxy objects with a given interface.

SYNOPSIS

use IOC::Proxy::Interfaces;

my $proxy_server = IOC::Proxy->new({
interface => AnInterface,
# ... add other config values here
});

$proxy_server->wrap($object);
# our $object is now proxied, but only the
# methods which are part of the interface
# will work, all others will throw exceptions

$object->method_in_interface(); # works as normal

$object->method_not_in_interface(); # will thrown an exception

This is a subclass of IOC::Proxy which allows for the partial proxing of an object. It will only proxy the methods of a given interface, all other methods will throw a IOC::MethodNotFound exception. This could be used to (in a very weird way) emulate the concept of upcasting in Java, it is also somewhat like the idea of using interfaces with Dynamic Proxies in Java as well (see the article link in "SEE ALSO").

This proxy can be useful if you need to have an object strictly conform to a particular interface in a particular situation. The interface class is also pushed onto the proxies @ISA so that it will respond to UNIVERSAL::isa($object, Interface) correctly. Keep in mind that there is no need for the object being proxied to have the interface in its @ISA prior to being proxied. The proxy is dynamic and only requires that the object conform to the interface when it is being wraped but the proxy object.

Pxytest is a command line utility to test a host for open proxies that are vulnerable to spammer abuse.

Unsecured proxies currently are the most significant conduit of junk email. This is a particularly vexing problem, because open proxies, unlike open mail relays, hide the origin of the spam, making it impossible to trace. This utility tests a host to see if it is vulnerable to such abuse.

The following types of unsecured proxies are detected: http-connect, http-post socks4, socks5, wingate, telnet and cisco. See the manual page for descriptions of these proxy types.

If you find this utility useful, you also may be interested in its sister utility, the rlytest open relay tester.

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)

Bypass Proxy Client is the complete network privacy tool. It ensures absolute privacy wherever you maybe, preventing would-be snoopers from monitoring your surfing, email, or chatting activity.

Japt-Proxy is a JAVA based Caching Proxy for Debians APT-System. Japt-Proxy is very reliable and lightning fast. Japt-Proxy is usually used in environments where several Debian systems have to be kept up-to-date without downloading the same files over and over again from the debian mirrors. Mostly these environments are data centers, Linux-powered companies, schools, public authorities and so on.
Often Japt-Proxy is used because of small sized internet connections but it is also useful to install complete debian systems over the net (read: over the proxy). Even with high volume internet connections Japt-Proxy can dramatically reduce the time to install or update Debian on many machines.
Why Java?
I know there are people out there thinking "Hey? Why Java?". There are a bunch of reasons why people asking those questions. I have a simple answer to all those questions. The answer is, that Java enabled me to easily develop the fastest and most reliable APT-Proxy. Java and the Apache Software Foundation provides such good libraries for this job, that it wasnt very hard to bring up this tool.
If you dont trust, test it - the installation takes less than five minutes!
Doesnt a general proxy server supersede an APT-Proxy?
No, it doesnt. Japt-Proxy knows the characteristics of a Debian archive and their files. It knows, for example, that .deb files wont change, because newer files would have a new name (the version is always part of the filename), hence it wont recheck if there is a newer version of this specific file.
Furthermore you can configure the Japt-Proxy to delete old versions of a package in its cache directory - a general proxy cache would simple delete files that havent been requested for some time.
So, a general caching proxy like Squid is a perfect tool for caching "normal" internet traffic. If you need a proxy for faster APT access - Japt-Proxy is the right tool for you.
Main features:
- Caching of all apt requests from Debian archives
- Multi-threaded architecture which increases the download speed enormously when several machines are requesting packages
- Builds up a partial mirror directory automatically, with exactly the same directory structure and filenames as the original mirror
- Automatic and configurable cache cleanup (purging packages in cache if newer versions exists)
- Makes sources.list configuration easier for multiple machines - if you change your internet backend server you only have to make the change once in Japt-Proxy, instead of on all Debian machines
- Works with multiple architectures
- Backend support for HTTP and FTP
- existing .debs can be copied into the Japt-Proxy cache directory (from a CD or DVD for example) and will be used by the Proxy automatically
