Fortunately, Linux isn't Windows......you are going to find lots of Windows "standard" protocols that aren't documented nor supported by anyone else. > Did I miss something? Well, Microsoft did.....there is RFC2131 that describes how you are supposed to use an ARP to respond to a duplicate IPv4 used on the network. It is commonly used to ensure you don't have systems manually configured or not honoring leases when DHCP is handing out dynamic IP addresses. Everyone else seems to implement this properly. > I did not find an kernel option saying something about ARP... That's because it implements the standard protocols by default. > Any ideas? Run DHCP or properly manually configure your Linux system. I don't know how old your Linux kernel is for the 8xx, but this support for RFC2131 has been in Linux for a very long time.
