A Fluke Network tester is unable to get a DHCP lease on a given
network and keeps declining every lease offered to it by
dhcpd3.3.1. If everybody was declining leases, I would think we
had a rogue dhcp server, but a sniffer capture shows there is
none. The message reads:
dhcpd: DHCPDECLINE of 18.104.22.168 from 00:c0:17:b6:1a:06 via em0: not found
On a different subnet, we saw an Iphone decline one
lease which was reported "abandoned" afterward and it did
successfully obtain a lease on the next try so I don't think
that is the same problem.
Interestingly enough, the Fluke did obtain a lease on
one of the other subnets but it absolutely refuses to take any
lease I offer it when talking directly through the interface.
Other systems in the same subnet as the actual em0 interface
