Free irc chat rooms software for linux

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.

IoChatto is a chat client which you can use in the JXTA platform.

Its interface is similar to many IRC chat clients, but you can have presence information for every channel, and its design is fully decentralized.

IRC-Chess project is a 2-player chess game for IRC which turns a computer into an IRC chess bot.

It consists of a Java chess server, with frontend scripts to convert an IRC client into a chess bot. Players then communicate with the bot using standard IRC commands, and dont require any special software to play.

Frontend scripts are available for IRSSI and X-Chat.

The client is merely responsible for interpreting this data and displaying it. In this way, porting the system to a variety of IRC clients is very simple, since
the client script will be short, and effectively contain no code specific to the game being played.

In other words, the Java part is smart. The script is dumb and is just there to make things look pretty.

This idea works. Currently, client scripts have been designed for RSSI and XChat. Since both these programs use Perl for scripting, the scripts are practically identical, with a few client specific modifications.

Porting this script to other IRC clients shouldnt be too much of a hassle, since its just the frontend thats ported, not the chess game itself. Anyone wanting to create frontend scripts for other IRC clients, please feel free to do so.

The PROTOCOL file describes exactly what needs to be done.

Bozocas Webchat is a IRC chat applet.
Nowadays, an online chat is sometimes crucial.There are situations when your visitors dont have time to wait for an email answer. It might be because they need urgent tech support or because they need to close a deal quickly.
You might also need to offer special discounts, sales, or show to your customers information that is not provided on the web. Being able to chat to the customer online on his/her brief visit might give you the competitive advantage you need.
You need a customer service tool that allows your personnel to instantaneously communicate with your web site visitors.
With this in mind, we created Bocazas Live Support.
Main features:
- Can connect to any known IRC network (only registered versions).
- DCC Chat (Direct Connections) between users.
- Confortable environment to keep track of simultaneous private and public conversations.
- Support text colors.
- Support copy & paste.
- Support sending files between users.
- Support most of the IRC commands (map, links, mode, oper...)
- Support any language: English, Spanish, Chinese, Deutsch, Italian, Turkish... and you can add any other.

Voc is a stream-chat engine which is designed to work on high-loaded chat-servers. It is written in PHP, but uses Perl or C++ for Voc-daemon -- the special program to handle multiple user-connections. With Voc you can make a chat that will serve many conversations simultanously. And its html-based, so your chatters can use it from almost any browser.
The Voc-engine includes a lot of features so it will be interested not only for a big chat owners.
Whats so special about Voc-engine?
There are 2 classes of html-chats. Classic-type, with refreshing messages-window, And stream-type.
Refresh-type is known to everybody, so lets think about streams. What is the common way to introduce such functionality? Webmasters make cgi-script (PHP-script, jsp-srcpt, e.t.c) which checks for new messages every second (2,3...) and prints something to the client. Of course, you need one instance of the script for each client. Now calculate how many data-requests you need to process every second... At least two for each client -- get messages, get users-list.
Also dont forget about memory and CPU usage. For instance, if you have PHP-scripts and PHP is compiled as an Apache-module, be ready to spend 5 Mbytes of memory and 0.1-1% of CPU for each client (only for messages-window).Multiple it to number of users online.
Do you still want to use such scripts?
Is there any solutions? I guess, yes -- try Voodoo chat. It uses Perl- or C++-daemon which processes users-requests to a messages list. And you need just one daemon for all clients. This daemon takes approx. 10 Mbytes of memory for 100 users. CPU usage is also small (of course it depends on your CPU, i.e. for 100 users online it is 0.5% of Pentium 4 2.4 Ghz). Do you see the difference now?
Main features:
- Daemon-stream type (recommended)
- Classic-type (with refreshes)
- PHP-stream script (read text above and use this type only when you have less then 20 simultaneous visitors and cannot use daemon-type)
- JavaScript stream-emulation (refreshing hidden frame which just add text to the main message-window)
- Themes-support. You can use one of exisitng designes, or easily create your own
- rooms
- private messages
- ignoring
- you can enable to use bold, italic, underlined messages
- inline images
- personal info-page with photo for registered users
- avatars
- internal mini-mail system
- status (online/offline/not available/dont disturb)
- web-indicator (see example at the left)
- nick & string highlighing for personal messages
- anti-flood
- messages and ban/unban logging
- limits for maximum number of users and maximum number of users from one ip (anti-nick-flooding)
- graphical statistic, example
- admin-zone to manage the chat
- moderator-levels for registered users, so you can give someone permissions to ban/unban users, change rooms-info, edit/delete registered users

MOHA Chat is a chat solution which comes with a intuitive Web client and can run on most shared hosts. MOHA Chat consumes fewer resources on the server side and is fast on the client side.

The project uses AJAX to retrieve the chat messages and user status. The client polls the server at regular intervals. It currently supports only one-to-one chatting with the Web client. The Web client encrypts messages using a key unique to the client when sending a message to the server and vice versa.
