I dug a little deeper and could see that in our case the devices all use the same uid in the boot request, thus receiving the same ip address via dhcp. I guess the failing bootreply comes from the still memorized mac address of the device before.
To get it working I used the option "ignore-client-uids on;" in the dhcpd.conf. I can't tell if this issue is really a bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1665264 Title: isc-dhcp-server 4.3.3-5ubuntu12.6 BOOTREPLY to wrong MAC address To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1665264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
