Free modula 2 software for linux

mod_but is an Apache 2.x module designed to operate as reverse-proxy enhancement component. mod_but integrates with mod_rewrite, mod_replace, mod_proxy, mod_security, mod_headers and other standard modules.
Main features:
- Pre-Authentication (Login)
- Cookie based session handling between the client and the reverse-proxy. This session is referred "mod_but session"
- Cookie hiding of backend application cookies (shared memory store). This session is referred as "Backend Session"
- Session store
- Session termination (Logout)
- HttpOnly support
- FREE cookies support (which are not handled by mod_but)
- URL Authorization: Check if user is authorized requesting the desired URLs
- Restrict authentication=ok messages to backend login services

mod_view Apache 2.0 module allows for the display in plain text of the head, tail, or entire contents of a file with egrep like pattern matching.

Ideal for the remote viewing of log files when used in conjunction with the Alias, AliasMatch, or Rewrite directives. (Yes, this could have been done as a CGI script, but that wouldnt have been any fun.)

ModSecurity is an FREE and GPL lincesed software for intrusion detection and prevention engine for web applications.
Operating as an Apache Web server module, the purpose of ModSecurity is to increase web application security, protecting web applications from known and unknown attacks.
Enhancements:
- This version fixes the issue with subrequests, a problem with full-width Unicode encoding, and a few other small issues.
- It also bundles the most recent version of the Core Rules (which contains many improvements over the previous version) along with the updated documentation.

mod_backhand is an Apache module that allows seamless redirection of HTTP requests from one web server to another. This redirection can be used to target machines with under-utilized resources, thus providing fine-grained, per-request load balancing of web requests.
Backhand is a project that was initiated in class at The Johns Hopkins University in The Department of Computer Science. After a simple proof of concept, written in C++, the project was pursued as a graduate qualifier project.
A proof of concept was realized, but a deployable product was needed. In order for public use, testing and, ultimately, acceptance, we wished to provide drop-in functionality in the most popular web server on the net.
mod_backhand was born. This drop-in module for the Apache Web Server provides a turnkey solution for intra-cluster redirection of HTTP on a per-request basis. The redirection is based on various system resources available within the cluster. This service is provided seamlessly, preserving remote host information for access/authentication purposes.
As with the methodology of Apache, the redirection mechanism can be enabled or disable for individual directories.
System resources are announced by the module to the cluster via ethernet broadcasts and/or IP multicasts. These resources are made available to the decision making algorithms that drive mod_backhand.
Supporting the following platforms:
- Linux (since release 0.5)
- Solaris (since release 1.0)
- BSDI (since release 1.0.5)
- (Net|Free|Open)BSD (since release 1.0.5)
- Linux (alpha fix) (since release 1.0.7)
- FreeBSD (since release 1.0.8)
- FreeBSD-4.x (since release 1.2.0)
- Windows NT through ntbhb (see related links) (since release 1.2.1)
Enhancements:
- Fixed brown-paper-bag problem with byBusyChildren. It was internally calling byLoad.
- Add diagnostics for erroneous MulticastStats entries -- Ben Laurie
- Setting no MulticastStats is fatal -- Ben Laurie
- Mac OS X resource acquisition fix -- Marquis Logan
- Use apache notes to prevent infinite recursion in the event that failure causes local handling and local handling is backhand_redirection.
- Allow the first argument in the two argument MulticastStats form to be a hostname (rather than IP).
- Various CRLF fixes from Kevin Walters.

XMLBeans project is a technology for accessing XML by binding it to Java types. XMLBeans provides several ways to get at the XML, including:
- Through XML schema that has been compiled to generate Java types that represent schema types. In this way, you can access instances of the schema through JavaBeans-style accessors after the fashion of "getFoo" and "setFoo".
- The XMLBeans API also allows you to reflect into the XML schema itself through an XML Schema Object model.
- A cursor model through which you can traverse the full XML infoset.
- Support for XML DOM.
Start off with your own stuff:
If you want to get right to it with your own XML schema and instance, follow these basic steps:
Install XMLBeans.
Compile your schema. Use scomp to compile the schema, generating and jarring Java types. For example, to create a employeeschema.jar from an employeesschema.xsd file:
scomp -out employeeschema.jar employeeschema.xsd
Write code. With the generated JAR on your classpath, write code to bind an XML instance to the Java types representing your schema. Heres an example that would use types generated from an employees schema:
File xmlFile = new File("c:employees.xml");
// Bind the instance to the generated XMLBeans types.
EmployeesDocument empDoc =
EmployeesDocument.Factory.parse(xmlFile);
// Get and print pieces of the XML instance.
Employees emps = empDoc.getEmployees();
Employee[] empArray = emps.getEmployeeArray();
for (int i = 0; i < empArray.length; i++)
{
System.out.println(empArray[i]);
}
Enhancements:
- Updated to the latest XMLSchema.xsd - January 25, 2006
- Updated XmlBeans to work with SaxonB-8.6.1 in place of SaxonB8.1
- XQuery external variable binding support

mod_auth_shadow is an Apache module for authentication using /etc/shadow.

When performing this task one encounters one fundamental difficulty: The /etc/shadow file is supposed to be read/writeable only by root. However, the webserver is supposed to run under a non-root user, such as "nobody".

mod_auth_shadow addresses this difficulty by opening a pipe to an suid root program, validate, which does the actual validation. When there is a failure, validate writes an error message to the system log, and waits three seconds before exiting.

Wmufo is a dockable application which monitors your seti@home client statistics.

Objective Modula-2 programming language is a hybrid between Smalltalk and Modula-2 based on the object model and runtime of Objective-C.

The design is an example how native Cocoa/GNUstep support can be added to static imperative programming languages without implementing a bridge.

The projects scope encompasses the design of the Objective Modula-2 programming language and the implementation of a compiler to implement it. The initial compiler will generate Objective-C source code.
