Try disabling the "firewall" (it's actually just a packet filter) for that particular network interface, or for the entire machine if you're not connected to any hostile networks (System->Administration->Firewall->"Disable"). My understanding of the GigE camera protocol is that there's a control port which is used to negotiate a port for data transfer. The camera then tries to connect to that port on the host. The issue is that the packet filter. I've updated the Troubleshooting page to cover that. http://www.ros.org/wiki/prosilica_camera/Troubleshooting Rene -- ------------------------------------------------------------ Dipl.-Inf.
