Web Ping is a program for testing your internet connection.

Web Ping is a simple application to test an internet connection to a perticular site. I created this application after my work moved locations and half our network stayed in the old building and the other half moved with us to the new location.

A flaky (significant point) VPN was set up to keep the two connected. Since a couple of the unmoved servers were of interest to me, I keeped checking to see if they were still accessable with the ping command before doing any serious work with them.

A quick and pathetic Google resulted in no other program that meet my needes, so I wrote one.

Insted of doing an actual network ping, Web Ping tests a connection by downloading a web page on a given server. The size of the page and time are stored in memory and the times are graphed. In this way, sites that block network a ping can still be tracked.

Web Ping also keeps track of the largest and smallest download times per session and also tracks the max and min values currently on the graph. Times of interest are graphed in a color which represents if it is a max or a min. (see figure one). The history tab also lists all the max values as they have been recevied.

A running average is also calculated with each download. The files downloaded are not processed or stored in any way. This prevents any security problems that can normaly happen in a web browser enviroment. The only two pecies of information retained about a downloaded file is the size and time.

Usage:

There are two ways to use Web Ping, GUI or CLI mode. The simplest of the two modes is CLI. Web Ping can be started in CLI mode by passing a url to the jar file in a command line interface like this: "java -jar WebPing.jar http://localhost". Web Ping will automaticly start getting statistics on the requested url, printing results to the screnn.

To quite, press q and then then ENTER key. CLI allows the user to Most people will probably want to use the GUI mode which has a history graph and allows the user to start and stop the session.

The best way to run Web Ping is in GUI mode. GUI mode allows the user start and stop the ping process at will and to change the site that is pinged. Users can also see more information about about the history of the pings and view max values and min values easily. There are three tabs on the top of the page, the first is the application, second is the history list, and the last give information about the application.

fBuilder project is a web-based utility for building and configuring your iptables or ipchains based Linux firewall. Written by the author of fwconfig, our fBuilder product line brings you many new and exciting features that will fit your firewall creation needs.
InnerTek Software currently offers two versions of fBuilder: fBuilder Lite - a free, ipchains only version of fBuilder that includes a standard set of features and fBuilder Plus - includes edit, insert, and delete capabilities for firewall rules, automatic back traffic rule creation, log reporting and export capabilities.
Our fBuilder products are also great for administering existing firewalls. When started, fBuilder will detect your running firewall and allow you to save it to a file. From that point, you can modify your firewall with the expert add utility or by using the edit/insert capabilities of fBuilder Plus.
Main features:
- Authentication
- User administration
- An enhanced firewall creation utility (known as the wizard)
- Much stronger scripts that add:
- SYN flood protection
- Spoof protection
- Disabling source-routed packets
- More...
- An expert add utility to allow users to build an entire firewall from scratch with much more control than allowed by the wizard including full support for:
- ICMP types
- SYN/ACK conditionals
- TOS bit manipulation
- Packet logging
- The invert option
- fBuilder ships with a pre-configured version of the boa web server, so there is no need to deal with Apache configuration files.

Porcupine is a web application server that provides an object oriented framework for developing web applications rapidly.

Many of the tasks required for building web applications as you know them, are either eliminated or simplified. For instance, when developing a Porcupine application you dont have to design a relational database. You only have to design and implement your business objects as classes, using the building blocks provided by the framework (datatypes). Porcupine integrates a native object database, no mapping required.

Another tedious task for web applications is the interface design, and the constraints imposed by HTML. QuiX, the servers integrated XUL motor, simplifies the interface design process. All you have to do is describe your applications interface in XML and write the appropriate event handlers. You dont have to waste time and money on widget implementations. QuiX comes with a variety of ready to use widgets, accelerating the development process.

Generally, every Porcupine application consists of three distinct layers. The first is the business layer consisting of the business objects which encapsulate the business logic.
The second layer binds the HTTP protocol with the first layers business objects. This layer is implemented using Python Server Pages or Servlets. If using XML-RPC, one common approach is to directly map an XML-RPC method to a business objects method.
The third layer, the presentation layer, usually consists of XML UI definitions and JavaScript event handlers.

The first two layers are executed server side and the third layer is executed on the client (browser).

SVN::Web provides a Web interface to Subversion repositories.
You can browse the tree, view history of a directory or a file, see whats changed in a specific revision, track changes with RSS, and also view diffs.
SVN::Web also tracks the branching feature (node copy) of Subversion, so you can easily see the relationship between branches.
Enhancements:
- The "reposparent" functionality was inadvertently broken in 0.50.
- This release fixes it.

Bigtop::Docs::Tutorial is a simple case study of building a web app with bigtop.
Note on What to Read
This document explains how to build an app of moderate complexity by typing in a bigtop file. Since it was written, tentmaker has come along. It is a browser delivered editor for bigtop files, see Bigtop::Docs::TentTut for details.
If you need a simpler example than the one shown here, consider the one table address book example in Gantry::Docs::Tutorial.
Driving Idea
Many (not all) applications are mostly data managers. That is, they are really intermediaries between users and various tables in a database. A bigtop file is meant to be a single place to describe all (or practically all) facits of the data in an application. This includes at least:
The name and special features of each controller.
- The name of each table in the database.
- A description of each column (field) in each table in the database. This includes at least:
its name and SQL type
- the label the user sees for it when it appears on the screen
- what type of html form element the user uses to enter or update it
- how the data is validated and filtered on its way into and out of the database (filtering not yet supported)
- which table the field refers to if it is a foreign key
- etc.
All of these things, and more, are described in a Bigtop file. That file can be given to bigtop to build the application. Once it is built, it can be safely rebuilt so that only the generated bits are changed (this is accomplished by maintaining a clean separation between generated and hand edited files, and by config options in the bigtop file).
Notice that nothing in the above has committed you or me to any particular web application framework, data modeling scheme, templating system, or web server. Bigtop is neutral (think big tent), at least for Perl apps delivered via the web.
