[Bug 1665264] Re: isc-dhcp-server 4.3.3-5ubuntu12.6 BOOTREPLY to wrong MAC address

I have tried this, too. I added the option "ignore-client-uids on;" and deleted the lease file. After restarting the server I could boot several targets. I also don't know if this is a bug or not. -- 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
[Bug 1665264] Re: isc-dhcp-server 4.3.3-5ubuntu12.6 BOOTREPLY to wrong MAC address
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
[Bug 1665264] Re: isc-dhcp-server 4.3.3-5ubuntu12.6 BOOTREPLY to wrong MAC address
I can confirm the bug description.
Ubuntu 16.04.2 LTS
isc-dhcp-server 4.3.3-5ubuntu12.6
dhcpd.conf used:
subnet 192.168.255.0 netmask 255.255.255.0
{
range dynamic-bootp 192.168.255.2 192.168.255.99;
allow bootp;
if substring (option vendor-class-identifier, 0, 10) = "AM335x ROM"
{
filename "barebox-mlo.img";
}
elsif substring (option vendor-class-identifier, 0, 10) = "am335x bar"
{
filename "barebox.img";
}
range 192.168.255.100 192.168.255.199;
}
Trying to boot the second target sends the BOOTREPLY to the MAC of the first
target:
