NTLM Authorization Proxy Server is a proxy software that allows you to authenticate via an MS Proxy Server using the proprietary NTLM protocol.
Since version 0.9.5 APS has an ability to behave as a standalone proxy server and authenticate http clients at web servers using NTLM method.
It can change arbitrary values in your clients request header so that those requests will look like they were created by MS IE. It is written in Python v1.5.2 language.
Main features:
- supports NTLM authentication via parent proxy server (Error 407 Proxy Authentication Required);
- supports NTLM authentication at web servers (Error 401 Access Denied/Unauthorized);
- supports translation of NTLM scheme to standard "Basic" authentication scheme;
- supports the HTTPS CONNECT method for transparent tunnelling through parent proxy server;
- has ability to change arbitrary values in clients request headers;
- supports unlimited number of client connections;
- supports connections from external hosts;
- supports HTTP 1.1 persistent connections;
- stores users credentials in config file or requests password from a console during the start time;
- supports intelligent failure detection and failover between multiple upstream proxies;
Enhancements:
- This release fixes a minor bug with Python 1.5.2 compatibility.

Firewall and Proxy Server HOWTO project is designed to describe the basics of firewall systems.

And also to give you some detail on setting up both a filtering and proxy firewall on a Linux based system.

Firewalls have gained great popularity as the ultimate in Internet Security.

Today firewalls are a part of almost every networking device. Like most hot subject they are also often misunderstood.

This HOWTO will go over the basics of what a firewall is and how to set one up.

I am using kernel 2.2.14 and RedHat 6.1 to develop this howto so the examples here are based on this distribution.

If you find differences in your distribution, please email me and Ill update this howto.

IMAP Proxy server is a caching IMAP proxy server. It was written to compensate for webmail clients that are unable to maintain persistent connections to an IMAP server. Most webmail clients need to log in to an IMAP server for nearly every single transaction.

This behaviour can cause tragic performance problems on the IMAP server. imapproxy tries to deal with this problem by leaving server connections open for a short time after a webmail client logs out.

When the webmail client connects again, imapproxy will determine if theres a cached connection available and reuse it if possible.

How does imapproxy keep track of which server connection is for which user?

Upon the first successful login to the real IMAP server (through the proxy), imapproxy fills in a little record that contains the username, an md5 digital signature of the password and the server socket descriptor thats being used.

After you log out and then log back in again, imapproxy just has to find a record that matches your username and password. These records are stored in a hash table (with the username being the hash key) in memory, so the lookups are pretty fast.

Can IMAP Proxy support multiple backend servers?

If you want IMAP Proxy to be able to proxy to multiple backend IMAP servers, you can run multiple instances of IMAP Proxy and make sure each instance is looking at a different configuration file.

Before you do this, take a look at perdition which appears to have been designed with this specific task in mind.

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.

LiteSpeed web server is an Apache interchangeable, full-featured high performance, secure HTTP server specifically engineered from the ground up with security and scalability in mind.
LiteSpeed Web Server is engineered to be Apache interchangeable, which means LiteSpeed has all the flexibilities that Apache has, but in much faster manner, such as distributed configuration .htaccess support.
The most commonly used Apache modules have been implemented in LiteSpeed with similar functionality and configuration, but completely different design and implementation.
Currently, LiteSpeed uses Apache compatible configuration for .htaccess and URL rewriting and eventually LiteSpeed will be able to use Apaches configuration file directly. This makes your switching between Apache and LiteSpeed very easy and risk free.
LiteSpeed Web Server has superb performance. Our measurements shows that it is more than 6 times faster than Apache, beating other lightweight content accelerators, such as thttpd, boa and TUX when serving static content, plus up to 50% increase in PHP performance than that of Apaches mod_php and more than doubled CGI/Fast CGI performance.
When you compare LiteSpeed Web Server to highly regarded and highly priced Zeus Web Server, you will find a lot of things in common: similar architecture and similar feature set, including some of the advanced features like web administration interface, MS FrontPage support, URL Rewriting, .htaccess and LDAP authentication. The biggest difference is that LiteSpeed is much more affordable, actually, it could cost you nothing.
LiteSpeed Web Server is also a real-world proven high performance content accelerator, compression proxy, and application security gateway leveraged by its highly scalable, low latency proxy engine.
With the combination of ease of use, tight security, outstanding performance, scalability, and reliability, LiteSpeed Web Server is the ultimate web server you ever need!
Main features:
- Backward compatible with HTTP/1.0
- Chunked Transfer Encoding
- Basic Authentication (htpasswd and LDAP backend)

Spike Proxy is an open source HTTP proxy for finding security flaws in web sites.

SPIKE Proxy is part of the Spike Application Testing Suite and supports automated SQL injection detection, web site crawling, login form brute forcing, overflow detection, and directory traversal detection.

To Use:

python spkproxy.py [ optional port argument, 8080 is default ]
Then set up your browser to use that port for both HTTP and
HTTPS proxies.

Then watch the traffic go!

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.
