% DHCP4_HOOK_PACKET_RCVD_SKIP received DHCPv4 packet was dropped, because a callout set the skip flag.
This debug message is printed when a callout installed on the pkt4_receive
hook point sets the skip flag. For this particular hook point, the
setting of the flag instructs the server to drop the packet.

% DHCP4_HOOK_PACKET_SEND_SKIP prepared DHCPv6 response was not sent, because a callout set skip flag.
This debug message is printed when a callout installed on the pkt4_send
hook point sets the skip flag. For this particular hook point, the setting
of the flag instructs the server to drop the packet. This means that
the client will not get any response, even though the server processed
client's request and acted on it (e.g. possibly allocated a lease).

% DHCP4_HOOK_SUBNET4_SELECT_SKIP no subnet was selected, because a callout set skip flag.
This debug message is printed when a callout installed on the
subnet4_select hook point sets the skip flag. For this particular hook
point, the setting of the flag instructs the server not to choose a
subnet, an action that severely limits further processing; the server
will be only able to offer global options - no addresses will be assigned.

261

262
% DHCP4_PARSER_EXCEPTION failed to create or run parser for configuration element %1
263
On receipt of message containing details to a change of its configuration,
264
the DHCPv4 server failed to create a parser to decode the contents of
265 266
the named configuration element, or the creation succeeded but the parsing
actions and committal of changes failed.  The message has been output in
267 268 269
response to a non-BIND 10 exception being raised.  Additional messages
may give further information.

270 271
% DHCP4_PARSER_FAIL failed to create or run parser for configuration element %1: %2
On receipt of message containing details to a change of its configuration,
272

287 288 289
This debug message indicates that an address was released properly. It
is a normal operation during client shutdown.

290
% DHCP4_RELEASE_EXCEPTION exception %1 while trying to release address %2
291 292 293 294 295
This message is output when an error was encountered during an attempt
to process a RELEASE message. The error will not affect the client,
which does not expect any response from the server for RELEASE
messages. Depending on the nature of problem, it may affect future
server operation.
296

297
% DHCP4_RELEASE_FAIL failed to remove lease for address %1 for duid %2, hwaddr %3
298 299 300 301 302 303 304
This error message indicates that the software failed to remove a
lease from the lease database. It is probably due to an error during a
database operation: resolution will most likely require administrator
intervention (e.g. check if DHCP process has sufficient privileges to
update the database). It may also be triggered if a lease was manually
removed from the database during RELEASE message processing.

305
% DHCP4_RELEASE_FAIL_NO_LEASE client (client-id %1, hwaddr %2) tried to release address, %3, but there is no such lease.
306
This warning message is printed when client attempts to release a lease,
307
but no such lease is known to the server.
308

309
% DHCP4_RELEASE_FAIL_WRONG_CLIENT_ID client (client-id %2) tried to release address %1, but it belongs to client (client-id %3)
310 311 312 313 314 315
This warning message indicates that client tried to release an address
that belongs to a different client. This should not happen in normal
circumstances and may indicate a misconfiguration of the client.  However,
since the client releasing the address will stop using it anyway, there
is a good chance that the situation will correct itself.

316
% DHCP4_RELEASE_FAIL_WRONG_HWADDR client (client-id %2) tried to release address %1, but sent from a wrong hardware address (%3)
317
This warning message indicates that client tried to release an address
318 319 320 321
that does belong to it, but the lease information was associated with
a different hardware address. One possible reason for using different
hardware address is that a cloned virtual machine was not updated and
both clones use the same client-id.
322

323
% DHCP4_RESPONSE_DATA responding with packet type %1, data is <%2>
324 325
A debug message listing the data returned to the client.

53 is unrecognized by the server. The valid message types are listed
on the IANA website: http://www.iana.org/assignments/bootp-dhcp-parameters/bootp-dhcp-parameters.xhtml#message-type-53.
The message will not be processed by the server.

% DHCP4_UNSUPPORTED_RCVD_PACKET_TYPE received message (transaction id %1), having type %2 is not supported
This debug message indicates that the message type carried in DHCPv4 option
53 is valid but the message will not be processed by the server. This includes
messages being normally sent by the server to the client, such as Offer, ACK,
NAK etc.
