开源的web会议(installing dimdim on ubuntu linux)

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 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

maxThreads="1500" minSpareThreads="250" maxSpareThreads="750"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />

Change to

maxThreads="1500" minSpareThreads="250" maxSpareThreads="750"
enableLookups="false" redirectPort="8443" acceptCount="100"
connectionTimeout="20000" disableUploadTimeout="true" />

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= 
email.user=
email.password=
email.sender= 
email.PORT=

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 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

Obviously this is not an ideal way to restrict it, but it seems to be being worked on.
