Dimdim is a cool new open source meeting service that lets you share your desktop, presentations, audio and video. Its also web based, and needs no installing. On top of all this, it works on Mac, Linux and even Windows! Its still alpha at the moment, but definately useable. Heres how to install it on Ubuntu server 6.06 or {insert your distro here}. The readme that comes with the tarball is very good, so have a look at that as well, but here are the basics: Install Ubuntu base system Just boot the ubuntu server cd and choose INSTALL TO HARD DISK. Install java sudo aptitude install sun-java5-jre Download dimdim from http://sourceforge.net/project/showfiles.php?group_id=176809 and move it to /usr/local/dimdim tar zxvf dimdim_160_Alpha_080307.tar.gz #The version number is likely to be different
sudo mv dimdim /usr/local/ Configure dimdim cd /usr/local/dimdim Edit server.xml vi server.xml Edit the port definition, 80 is probably the easiest, but change it to taste <!-- Define a non-SSL HTTP/1.1 Connector on port 8080 -->
<Connector port="DIMDIM_PORT_NUMBER" maxHttpHeaderSize="8192"
maxThreads="1500" minSpareThreads="250" maxSpareThreads="750"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
<!-- Note : To disable connection timeouts, set connectionTimeout value
to 0 -->
Change to

maxThreads="1500" minSpareThreads="250" maxSpareThreads="750"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />
<!-- Note : To disable connection timeouts, set connectionTimeout value

Edit dimdim.properties
Edit the following parameters: vi dimdim.properties dimdim.serverAddress # should be your server url, ie dimdim.mydomain.com
dimdim.serverPortNumber=80 # change if you use a different port and lastly the email config email.server=<smtp server address>
email.user=<smtp user name>
email.password=<smtp user password>
email.sender=<full email address of the above user>
email.PORT=<smtp port number> Now edit the wrapper.conf for the java path: vi ConferenceServer/apache-tomcat-5.5.17/conf/wrapper.conf # Java Application #wrapper.java.command=DIMDIM_JAVA_HOME/bin/java wrapper.java.command=/usr/bin/java # add this line for ubuntu, or change according to where java is on your system All done, now just start the beast sudo /usr/local/dimdim/dimdim start If that all works, you can now go to http://your.server.address and start using dimdim Add service links dimdim comes with a service wrapper, which makes it pretty easy to put into your *nix system. First we add a soft link to /etc/init.d/, then make sure it starts up when the server reboots. sudo ln -s /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/bin/dimdim /etc/init.d/ sudo update-rc.d dimdim defaults Restrict presenter access You may want to restrict the users that can start a presentation. At the moment, there is a very basic way to do this: Edit /usr/local/dimdim/ConferenceServer/apache-tomcat-5.5.17/webapps/dimdim/WEB-INF/dimdimPresenters.txt and add the email addresses allowed to start a presentation. No, theres no authentication. Edit /usr/local/dimdim/dimdim.properties and set dimdim.authenticationPolicy=CHECK_EMAIL Restart dimdim _____________________________________________________________________________ Thanks to http://techgurulive.com/2008/11/12/how-to-install-dimdim-on-ubuntu-linux/
