Download the proper archive and extract it to a temporary folder. The only difference between Linux and Windows distributions is the compression format used. There is also a start/stop utility named 'realchat' in the Linux distribution.
Copy the contents of the /server
folder to a folder where you
want your chat server to live.
For example:
/home/username/rcs/
Set the permissions of the start/stop script realchat
to be executable.chmod a+x ./realchat
Copy the contents of the /client
folder to a folder inside your
web server's document tree.
For example:
/home/user/public_html/chat/
If needed set file and folder permissions, so they can be readable.
chmod a+r *
You need to modify the 'Config section' of the script to match your system configuration:
Sample 'realchat' script here.SERVERDIR="/home/username/rcs" JAVADIR="/usr/lib/jdk1.1/bin" TTY=null
