XHR Chat is a demonstration type chat script I wrote when experimenting with xmlHttpRequest. It never refreshes, keeps an infinite post log, and checks for new posts once a second.

XHR Chat will degrade gracefully if the browser doesnt support xmlHttpRequest, just so long it still has javascript enabled.

Small Telnet Chat provides a chat server to which you can connect via a telnet client.

No special installation procedure is required. Simply unpack the archive into a directory and run it.

The configuration file (config.xml) has to be in the same directory as the server.

For those who want to put the server to place where executables usually reside (/usr/local/bin, etc.), a .jar file is provided.

Running

To run the chatserver, cd into the directory into which you have copied the files.

Run the server by typing:
java stc

ARSC Really Simple Chat is a Web chat system that uses PHP and MySQL.
ARSC Really Simple Chat project works with every browser in existence, even text-based ones, and it uses the server push technique or, if possible, its own socket server.
It is very simple to install and use ARSC. It includes some important features, such as operators, kick-ing, whispering, and more.
Multiple rooms and different languages are available. To run ARSC on your site, you need a Web server that understands PHP, and can connect to a MySQL database.
Main features:
- very easy installation
- multiple languages supported
- multiple browsers/platforms supported (even text-based ones)
- comfortable administration interface
- private rooms
- two-leveled moderation system with message queue and Moderator/VIP roles
- graphical smilies
- freely definable layouts, with different layouts possible for individual rooms and/or users
- ID-Cards for registered users, with individual guestbooks on every ID-Card
- text-browser interface even allows chatting with braille screen readers
- security: uses sha1 hashes for passwords and sessionids, and every single user input is checked against a regular expression of allowed values
- works with PHP 4 and PHP 5
- works with safe_mode = On and register_globals = Off
Once installed on your webserver, ARSC provides a chat interface to the visitors of your site. Your visitors need no special plugins or additional software to chat, only their webbrowser. ARSC is licensed under the GPL, which means it is free (like in "free speech"). It also comes at no cost (like in "free beer"). You may even use it in your own software projects.
Chatting with ARSC is very comfortable. If you have a modern browser with frame support and JavaScript support enabled, ARSC makes use of these technologies. If you have an older browser, or you have JavaScript disabled, or even if you have a browser that does not support frames, you can still chat with ARSC. Let me say it this way: With ARSC, chatting on a webpage is possible with every known browser under the sun that is still in use nowadays.
In contrary to many other PHP/MySQL webchats, ARSC can be run using a non-forking socketserver to handle all message transport. Other chats use the httpd process to handle the message transport, what causes a big overhead, while the socketserver of ARSC works very ressource-friendly and can handle way more users. The server is completely written in PHP and thus does not need any special requirements besides a cgi-bin installation of PHP 4.1.0 or above. Current versions of PHP (4.3.x) have been tested and work. If you are not able to compile a cgi-bin version of PHP or you may not start a socketserver on your machine, ARSC still offers the traditional message handling via the httpd process or even via meta refresh.
Enhancements:
- A bug that broke the installation routine was fixed.
