Apache::ReverseProxy is an Apache mod_perl reverse proxy.

SYNOPSIS

# In Apache config file
< Location / >
SetHandler perl-script
PerlHandler Apache::ReverseProxy
PerlSetVar ReverseProxyConfig /usr/local/apache/conf/rproxy.conf
< /Location >
# In rproxy.conf / http://www.cpan.org/

This is a reverse proxy module for Apache with mod_perl. It is intended to replace Apache::ProxyPass. Given a list of URI mappings, this module will translate an incoming URI, retrieve the contents for the translated URI, and return the contents to the original requestor. This module allows you to specify exact matching (instead of regular expression matching) and handles query string translations.

CONFIGURATION

You will need to set the ReverseProxyConfig perl variable in Apache to the path of the reverse proxy mapping file. For example:

< Location / >
SetHandler perl-script
PerlHandler Apache::ReverseProxy
PerlSetVar ReverseProxyConfig /usr/local/apache/conf/rproxy.conf

# Optional configuration items:
#PerlSetVar ReverseProxyChain http://proxy.mycompany.com:8888/
#PerlSetVar ReverseProxyNoChain mycompany.com
< /Location >

ReverseProxyChain specifies a proxy server to use. This is sometimes called proxy chaining when one proxy server uses another proxy server. The ReverseProxyNoChain directive can specify a domain to not use proxy chaining on.

Reverse proxy configuration files have three fields, each separated by white space. The first field is the uri to look for, the second field is the replacement uri, and the third field is optional and allows you to specify comma separated options for the mapping. The only option that is currently supported is the exact parameter, which will make the reverse proxy use exact matching for the first parameter instead of using regular expressions. This feature is convenient when the first parameter contains characters that may need to be escaped or quotemetaed. Exact options are evaluated first. If there isnt an exact match, regular expression matches are performed. Configuration files may contain comments, which start with a pound sign. For example:

/news/ http://www.news.com/
/ http://www.perl.com/
/stats http://localhost/stats exact
# /stats maps exactly to http://localhost/stats
# /stats/b maps to http://www.perl.com/stats/b
/french/news http://www.news.com/?language=french
# /french/news/index -> http://www.news.com/index?language=french
# /french/news/index?a=b -> http://www.news.com/index?language=french&a=b

Vulture is an HTTP reverse proxy. It does many security checks (authentication, rewriting, filtering) before proxying request from Internet to your web applications. With authentication enabled, vulture will open flows only to authenticated users.
VultureNG also allows to your users to use only one password to access many different applications by learning and forwarding their different accounts.
Main features:
- Authentication (SSL, LDAP/AD, SQL, Radius)
- Authentication forwarding (SSO)
- Headers modification on the fly
- Flow encryption
- Content filtering
- URL Rewriting
- Load balancing
Enhancements:
- AJAX in the administration interface (process restart).
- PKI authentication (for ACL syncro).
- ModSecurity2.
- An Oeufdure patch and a mimine patch.

File Beamer is an easy to use file transfer tool. The programm is platform independent. That means it runs with Windows 98/ME/2000/XP, Linux, Unix and MacOS X.

This is made possible by using Trolltechs Qt Library which provides an easy to use GUI toolkit, networking functions and a lot more.

File Beamer is free open source software and was released under the GPL license.

Usage:

Receiving files:

Click the "Receive" tab
If the receiver is behind a firewall or router, check "reverse connection" and enter the senders IP or host name. *
Click the "listen" button. The client can now receive files
When receving a file, a "Save as" dialog appears. Choose a place to safe the file.

Sending files:

Click the "Send" tab
If the receiver is behind a firewall or router check "reverse connection" *
Else input the target IP address or host name and port
Select a file to send either by typing the path or by clicking the "..." button
Click the "Send" button (target must be in listen mode)

VNC Reflector project is a specialized VNC proxy server.

VNC Reflector is a specialized VNC server which acts as a proxy between a real VNC server (a host) and a number of VNC clients.

It was designed to work efficiently with large number of clients. It can switch between different hosts on the fly, preserving client connections.

It supports reverse host-to-reflector connections, it can save host sessions on disk, and it also has other unique features.

This library defines set of data types and artithmetic operators, which can be used to code procedures with the intent to produce binary code which is difficult to analyse and reverse engineer.
This is achieved by moving all the calculations to yet another layer, which produces messy binary code being difficult to read and figure out, what calculations are actually performed and on which data.
Usage
The library provides arithmetic and logic operators to work with those data types. For example, addition performed in OBCODE would be coded as follows:
#include "obcode.h"
struct obyte ob1;
struct obyte ob2;
struct obyte obsum;
unsigned char sum;
obcode_init(0); /* Initialise obyte random */
obyte_set(&ob1, 12); /* Normal number 12 to obyte */
obyte_set(&ob2, 33); /* Normal number 33 to obyte */
obyte_add(&ob1, &ob2, &obsum); /* Perform OBCODE addition */
sum = obyte_get(&obsum); /* Return to normal world */
obcode_finish();
If those numbers were already encoded as obytes, people reverse engineering the code would never see 12 and 33, only messy operations on long, random looking data streams, eventually giving the product of 45.
Version restrictions:
- This library is still work in progress. It contains bugs and the operators set is very limited. Suggestions and improvements are welcome.
Enhancements:
- Code and documentation cleanups.
