Meeting Server Appliance bundles a product called WebHuddle that allows you to have online, browser based presentations (PowerPoint, Open Office Impress presentations), voice conferencing and even ap¬plication presentations. During a Web meeting, one can chat, ask/answer ques¬tions and host polls. All these happen in almost real time and require only a Web browser with a Java plugin. Let's jump right into the nitty-gritties of running this appliance. Login as root and change to the directory /var /webhuddle/bin and start Webhuddle as:

start oo.sh ./run.sh Wait for a minute to let WebHuddle start. Type in the URL http:/ / <ip-ad¬dress>:8080/. Substitute <ip-address> with the IP address of the appliance. Click on Accept, OK or Continue for all pop-up alerts (related to SSL certificate) you see while working on WebHuddle. You should be greeted by the main page of WebHuddle.
