Oh, for the record, regarding the issue discussed bellow about determining the NIC IP. When a server broadcast an UDP message, the client receiving it can fetch the server NIC IP from the result returned by the #receiveUDPDataInto: message. I only tested it on the same workstation, but I gue

I already tried the one you suggested, but it returns the loopback IP on P7. With the Henrik SSDP package, I can get the IP: SSDPParticipant new allLocalV4Addresses. However when I activate a second network interface, this last one returns an empty collection. When inactivating this second int

I think he means you can not discover all interfaces from Pharo. I have 2 network interfaces with addresses 192.168.0.4 and 192.168.56.1 Pharo only returns the first one. NetNameResolver localHostName "'thepc'". NetNameResolver localHostAddress. "#[192 168 0 4]" NetNameResolver nameForAddress: #

Hi Norbert, Just to be sure I understood correctly what you wrote regarding network interface: Do you mean it is impossible to discover the network interface IP address from the image? It is this IP the teacher Dr. Geo server needs to broadcast over UDP. Hilaire Le 08/05/2018 à 16:22, Henr
