Hi Mike, Was this capture taken at the endpoint or at the gk? If at the gk, the broadcast GRQs seem to be getting through; just enable the normal response to them and you should be fine without using multicast. If at the endpoint, well, it isn't sending out any multicast GRQs, so gnugk won't receive any ;) Perhaps you should ask QTI or the OpenH323 folks. --Stewart ----- Original Message ----- From: "Michael Ditum" <mrskensington@xxxxxxxxx> To: <openh323gk-users@xxxxxxxxxxxxxxxxxxxxx> Sent: Thursday, April 28, 2005 9:38 AM Subject: Multicast Discovery I'm trying to get multicast discovery to work as our system will have to be used on networks with switches that don't pass on broadcast traffic. But I'm having trouble getting it to work. I'm using openphone configured to "Discover Automatically" the gatekeeper but it just comes up with a message saying "Could not find the gatekeeper on LAN" I've tried examining whats happening using ethereal... I confiigured it with filter "igmp && h225" you can view the ethereal dump at http://leary.csoft.net/~mjd/ethereal.dump and the text version at http://leary.csoft.net/~mjd/server.txt I ran gnugk with the following command line gnugk -ttttt -o /var/log/gnugk.log -c /etc/gnugk/gnugk.ini there was no output after i started openphone so it appears that gnugk isn't handling the discovery. you can view the log at... http://leary.csoft.net/~mjd/gatekeeper.log You can view my gatekeeper.ini at http://leary.csoft.net/~mjd/gatekeeper.ini does anyone have any ideas why it may not be working??? thanks Mike ------------------------------------------------------- SF.Net email is sponsored by: Tell us your software development plans!
