[Bug 1274499] Re: dhcp lease rollover causes loss of access to managment IP

[Gavin Panella]

This appears to have happened in the Garage MAAS. Attached is the leases
file, which contains 141 static host maps, and references 145 different
hardware addresses. Below is a snippet from the dhcpd.conf file that was
being used at the time:

subnet 192.168.9.0 netmask 255.255.255.0 {
       filename "pxelinux.0";
       ignore-client-uids true;
       option subnet-mask 255.255.255.0;
       option broadcast-address 192.168.9.255;
       option domain-name-servers 192.168.1.25;
       option domain-name "cloud.mallards";
       option routers 192.168.9.1;
       option ntp-servers 91.189.94.4;
       range dynamic-bootp 192.168.9.10 192.168.9.150;
       class "PXE" {
          match if substring (option vendor-class-identifier, 0, 3) = "PXE";
          default-lease-time 30;
          max-lease-time 30;
       }
}
