488Part IVRunning ApplicationsVideoconferencing with GnomeMeetingThe GnomeMeeting window lets you communicate with other people over a net- work through video, audio, and typed messages. Because GnomeMeeting supportsthe H323 protocol (a standard for multimedia communications), you can use it tocommunicate with people using other popular videoconferencing clients, such asMicrosoft NetMeeting, Cu-SeeMe, and Intel VideoPhone. GnomeMeeting does not support the NetMeeting shared whiteboard functions, just videoconferencing. To be able to send video, you need a Webcam that is supported in Linux you llfind a few dozen models from which to choose. The following sections show youhow to set up your Webcam and use GnomeMeeting for videoconferencing. Getting a Supported WebcamAs with support for TV capture cards, Webcam support is provided through thevideo4linux interface. To see if your Webcam is supported, check the /usr/src/ linux*/Documentationdirectory. A few parallel-port video cameras are describedin the video4linuxsubdirectory; however, the bulk of the supported cameras arelisted in the usbdirectory. After doing some research, I purchased a Logitech QuickCam Pro 3000. The driverfor this Webcam was made for a Philips USB Webcam, but it also works forWebcams from Logitech, Samsung, Creative Labs, and Askey. Before making thepurchase, I checked out the driver s description at www.smcc.demon.nl/webcam. Supported USB cameras should be autodetected, so that when you plug them in, the necessary modules are loaded automatically. Just start up GnomeMeeting(gnomemeetingcommand), and you should see video from your Webcam on yourLinux desktop. You can check to see that your Webcam is working properly by typing the following: # lsmodpwc 43392 1videodev 5120 2 [pwc] usbcore 59072 1 [audio pwc usb-uhci] The output from lsmodshows that the pwc driver is loaded and associated with thevideodev module and usbcore module. Opening Your Firewall for GnomeMeetingYou need to open a variety of ports in your firewall to use GnomeMeeting. In partic- ular, you need to open TCP port 1720 and TCP port range 30000 to 30010. For UDPports, you must open ports 5000 through 5007 and ports 5010 through 5013. Examples of exact iptables settings you can use to open these ports are containedin the GnomeMeeting FAQ (www.gnomemeeting.org/index.php?rub=3). TipNote27_
