Webcam test in the IGEL Linux

Tuesday, May 22nd, 2012

If you want to check if a webcam works in general in the IGEL Linux, create a terminal session and start the session. Log in as root and type in/execute ls /dev/video* , the result should look like /dev/video0.

If you got no result the webcam will not work, if you got /dev/video0 type in: gst-launch-0.10 v4l2src device=/dev/video0 ! ‘video/x-raw-yuv,width=640,height=480,framerate=30/1’ ! xvimagesink and execute the command. If you have /dev/video1 or similar just change the command parameter to the right value. After the command is executed you should see the video picture from your webcam. Please note: this don’t mean the camera will work with Citrix, VMWare or whatever. This still needs to be tested but it’s a good indicator if the camera will work in general. If this fails, you can still try/use USB redirection of course.

Tip: IGEL Thin Clients don’t refresh there status in the UMS Console or don’t get a new configuration

Setup a DHCP Option 224 as string field or a DNS hostname “igelrmserver” which points to the management server. If using the DNS hostname make sure that the name can be resolved…

Make sure that the client-server communication port’s are open, see also http://www.papershare.com/app/paper.aspx?id=1617&o=3736

If using Linux based IGEL Thin Clients you can create a terminal session (IGEL Setup->Accessories) and after you start the terminal session use “ping igelrmserver” and “probeport +server name/ip+ 30001” to verify a working UMS connection. If using the DHCP option type in “cat /wfs/dhclient.leases.eth0”, you should now see the options provided by your DHCP incl. “option igelrmserver “+servername/ip+”;. If you can not read the servername/ip you have not used the string type for the DHCP Option 224 and you need to fix this in your DHCP Server configuration.
