That's the precise problem: the MAC address is not fixed. Or at least any MAC address in the hardware is being ignored. So DHCP is not a viable option. If I have a half dozen PIs in a system, each connected to a different transducer, it is mainly the MAC address that I can use to configure the system so I know which transducer I am communicating with. Unless I use a fixed IP address in each card. And I have to say it is unusual to have fixed IP addresses and random MAC addresses. -- Roger Oberholtzer -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
