Here's a sanitized dhcpd.conf:
Things in ALL CAPS and MAC addresses of all zeros are the bits that have
been changed. Also, sections of duplicated information have been reduced
to one example followed by a comment saying "More similar entries...".
I did some further testing to clarify my understanding of the "no
available billing" error. Initially, I thought this "lease limit reached
in all matching classes" was a more specific type of the "no available
billing" error (which is what we saw in previous versions), but that
doesn't seem to be the case.
We have a default lease limit of 2 for DSL customers. If they try to get
more than two leases, we see a log message for that customer of "no
available billing: lease limit reached in all matching classes". This is
The abnormal behavior is that we sporadically hit periods where we'll
see massive numbers of the same "no available billing: lease limit
reached in all matching classes" error for the wireless subnets or the
office subnet. None of these networks are configured with a lease limit
Here's an example of a log message in the abnormal situation:
May 4 19:14:01 peach dhcpd: DHCPREQUEST for 184.108.40.206 from 00:00:00:00:00:00 (USERNAME) via eth0: no available billing: lease limit reached in all matching classes
That IP is in a pool that should not be subject to a lease limit.
