Kea Messages Manual

Kea Messages Manual

This is the messages manual for Kea version 0.9.1-beta.

Abstract

This is the messages manual for Kea version 0.9.1-beta. The most up-to-date version of this document, along with other documents for Kea, can be found at http://kea.isc.org/docs.


Chapter 1. Introduction

This document lists each message that can be logged by the programs in the Kea package. Each entry in this manual is of the form:

IDENTIFICATION message-text

... where "IDENTIFICATION" is the message identification included in each message logged and "message-text" is the accompanying message text. The "message-text" may include placeholders of the form "%1", "%2" etc.; these parameters are replaced by relevant values when the message is logged.

Each entry is also accompanied by a description giving more information about the circumstances that result in the message being logged.

For information on configuring and using Kea logging, refer to the Kea Guide.

Chapter 2. Kea Log Messages

ASIODNS_FD_ADD_TCP adding a new TCP server by opened fd %1

A debug message informing about installing a file descriptor as a server. The file descriptor number is noted.

ASIODNS_FD_ADD_UDP adding a new UDP server by opened fd %1

A debug message informing about installing a file descriptor as a server. The file descriptor number is noted.

ASIODNS_FETCH_COMPLETED upstream fetch to %1(%2) has now completed

A debug message, this records that the upstream fetch (a query made by the resolver on behalf of its client) to the specified address has completed.

ASIODNS_FETCH_STOPPED upstream fetch to %1(%2) has been stopped

An external component has requested the halting of an upstream fetch. This is an allowed operation, and the message should only appear if debug is enabled.

ASIODNS_OPEN_SOCKET error %1 opening %2 socket to %3(%4)

The asynchronous I/O code encountered an error when trying to open a socket of the specified protocol in order to send a message to the target address. The number of the system error that caused the problem is given in the message.

ASIODNS_READ_DATA error %1 reading %2 data from %3(%4)

The asynchronous I/O code encountered an error when trying to read data from the specified address on the given protocol. The number of the system error that caused the problem is given in the message.

ASIODNS_READ_TIMEOUT receive timeout while waiting for data from %1(%2)

An upstream fetch from the specified address timed out. This may happen for any number of reasons and is most probably a problem at the remote server or a problem on the network. The message will only appear if debug is enabled.

ASIODNS_SEND_DATA error %1 sending data using %2 to %3(%4)

The asynchronous I/O code encountered an error when trying to send data to the specified address on the given protocol. The number of the system error that caused the problem is given in the message.

ASIODNS_SYNC_UDP_CLOSE_FAIL failed to close a DNS/UDP socket: %1

This is the same to ASIODNS_UDP_CLOSE_FAIL but happens on the "synchronous UDP server", mainly used for the authoritative DNS server daemon.

ASIODNS_TCP_ACCEPT_FAIL failed to accept TCP DNS connection: %1

Accepting a TCP connection from a DNS client failed due to an error that could happen but should be rare. The reason for the error is included in the log message. The server still keeps accepting new connections, so unless it happens often it's probably okay to ignore this error. If the shown error indicates something like "too many open files", it's probably because the run time environment is too restrictive on this limitation, so consider adjusting the limit using a tool such as ulimit. If you see other types of errors too often, there may be something overlooked; please file a bug report in that case.

ASIODNS_TCP_CLEANUP_CLOSE_FAIL failed to close a DNS/TCP socket on port cleanup: %1

A TCP DNS server tried to close a TCP socket (one created on accepting a new connection or is already unused) as a step of cleaning up the corresponding listening port, but it failed to do that. This is generally an unexpected event and so is logged as an error. See also the description of ASIODNS_TCP_CLOSE_ACCEPTOR_FAIL.

ASIODNS_TCP_CLOSE_ACCEPTOR_FAIL failed to close listening TCP socket: %1

A TCP DNS server tried to close a listening TCP socket (for accepting new connections) as a step of cleaning up the corresponding listening port (e.g., on server shutdown or updating port configuration), but it failed to do that. This is generally an unexpected event and so is logged as an error. See ASIODNS_TCP_CLOSE_FAIL on the implication of related system resources.

ASIODNS_TCP_CLOSE_FAIL failed to close DNS/TCP socket with a client: %1

A TCP DNS server tried to close a TCP socket used to communicate with a client, but it failed to do that. While closing a socket should normally be an error-free operation, there have been known cases where this happened with a "connection reset by peer" error. This might be because of some odd client behavior, such as sending a TCP RST after establishing the connection and before the server closes the socket, but how exactly this could happen seems to be system dependent (i.e, it's not part of the standard socket API), so it's difficult to provide a general explanation. In any case, it is believed that an error on closing a socket doesn't mean leaking system resources (the kernel should clean up any internal resource related to the socket, just reporting an error detected in the close call), but, again, it seems to be system dependent. This message is logged at a debug level as it's known to happen and could be triggered by a remote node and it would be better to not be too verbose, but you might want to increase the log level and make sure there's no resource leak or other system level troubles when it's logged.

ASIODNS_TCP_CLOSE_NORESP_FAIL failed to close DNS/TCP socket with a client: %1

A TCP DNS server tried to close a TCP socket used to communicate with a client without returning an answer (which normally happens for zone transfer requests), but it failed to do that. See ASIODNS_TCP_CLOSE_FAIL for more details.

ASIODNS_TCP_GETREMOTE_FAIL failed to get remote address of a DNS TCP connection: %1

A TCP DNS server tried to get the address and port of a remote client on a connected socket but failed. It's expected to be rare but can still happen. See also ASIODNS_TCP_READLEN_FAIL.

ASIODNS_TCP_READDATA_FAIL failed to get DNS data on a TCP socket: %1

A TCP DNS server tried to read a DNS message (that follows a 2-byte length field) but failed. It's expected to be rare but can still happen. See also ASIODNS_TCP_READLEN_FAIL.

ASIODNS_TCP_READLEN_FAIL failed to get DNS data length on a TCP socket: %1

A TCP DNS server tried to get the length field of a DNS message (the first 2 bytes of a new chunk of data) but failed. This is generally expected to be rare but can still happen, e.g, due to an unexpected reset of the connection. A specific reason for the failure is included in the log message.

ASIODNS_TCP_WRITE_FAIL failed to send DNS message over a TCP socket: %1

A TCP DNS server tried to send a DNS message to a remote client but failed. It's expected to be rare but can still happen. See also ASIODNS_TCP_READLEN_FAIL.

ASIODNS_UDP_ASYNC_SEND_FAIL Error sending UDP packet to %1: %2

The low-level ASIO library reported an error when trying to send a UDP packet in asynchronous UDP mode. This can be any error reported by send_to(), and can indicate problems such as too high a load on the network, or a problem in the underlying library or system. This packet is dropped and will not be sent, but service should resume normally. If you see a single occurrence of this message, it probably does not indicate any significant problem, but if it is logged often, it is probably a good idea to inspect your network traffic.

ASIODNS_UDP_CLOSE_FAIL failed to close a DNS/UDP socket: %1

A UDP DNS server tried to close its UDP socket, but failed to do that. This is generally an unexpected event and so is logged as an error.

ASIODNS_UDP_RECEIVE_FAIL failed to receive UDP DNS packet: %1

Receiving a UDP packet from a DNS client failed due to an error that could happen but should be very rare. The server still keeps receiving UDP packets on this socket. The reason for the error is included in the log message. This log message is basically not expected to appear at all in practice; if it does, there may be some system level failure and other system logs may have to be checked.

ASIODNS_UDP_SYNC_RECEIVE_FAIL failed to receive UDP DNS packet: %1

This is the same to ASIODNS_UDP_RECEIVE_FAIL but happens on the "synchronous UDP server", mainly used for the authoritative DNS server daemon.

ASIODNS_UDP_SYNC_SEND_FAIL Error sending UDP packet to %1: %2

The low-level ASIO library reported an error when trying to send a UDP packet in synchronous UDP mode. See ASIODNS_UDP_ASYNC_SEND_FAIL for more information.

ASIODNS_UNKNOWN_ORIGIN unknown origin for ASIO error code %1 (protocol: %2, address %3)

An internal consistency check on the origin of a message from the asynchronous I/O module failed. This may indicate an internal error; please submit a bug report.

ASIODNS_UNKNOWN_RESULT unknown result (%1) when IOFetch::stop() was executed for I/O to %2(%3)

An internal error indicating that the termination method of the resolver's upstream fetch class was called with an unknown result code (which is given in the message). Please submit a bug report.

CC_ASYNC_READ_FAILED asynchronous read failed (error code = %1)

This marks a low level error, we tried to read data from the message queue daemon asynchronously, but the ASIO library returned an error.

CC_CONN_ERROR error connecting to message queue (%1)

It is impossible to reach the message queue daemon for the reason given. It is unlikely there'll be reason for whatever program this currently is to continue running, as the communication with the rest of Kea is vital for the components.

CC_DISCONNECT disconnecting from message queue daemon

The library is disconnecting from the message queue daemon. This debug message indicates that the program is trying to shut down gracefully.

CC_ESTABLISH trying to establish connection with message queue daemon at %1

This debug message indicates that the command channel library is about to connect to the message queue daemon, which should be listening on the UNIX-domain socket listed in the output.

CC_ESTABLISHED successfully connected to message queue daemon

This debug message indicates that the connection was successfully made, this should follow CC_ESTABLISH.

CC_GROUP_RECEIVE trying to receive a message with seq %1

Debug message, noting that a message is expected to come over the command channel.

CC_GROUP_RECEIVED message arrived ('%1', '%2')

Debug message, noting that we successfully received a message (its envelope and payload listed). This follows CC_GROUP_RECEIVE, but might happen some time later, depending if we waited for it or just polled.

CC_GROUP_SEND sending message '%1' to group '%2'

Debug message, we're about to send a message over the command channel.

CC_INVALID_LENGTHS invalid length parameters (%1, %2)

This happens when garbage comes over the command channel or some kind of confusion happens in the program. The data received from the socket make no sense if we interpret it as lengths of message. The first one is total length of the message; the second is the length of the header. The header and its length (2 bytes) is counted in the total length.

CC_LENGTH_NOT_READY length not ready

There should be data representing the length of message on the socket, but it is not there.

CC_LNAME_RECEIVED received local name: %1

Debug message: the local module received its unique identifier (name) from msgq on completion of establishing the session with msgq.

CC_NO_MESSAGE no message ready to be received yet

The program polled for incoming messages, but there was no message waiting. This is a debug message which may happen only after CC_GROUP_RECEIVE.

CC_NO_MSGQ unable to connect to message queue (%1)

It isn't possible to connect to the message queue daemon, for reason listed. It is unlikely any program will be able continue without the communication.

CC_READ_ERROR error reading data from command channel (%1)

A low level error happened when the library tried to read data from the command channel socket. The reason is listed.

CC_READ_EXCEPTION error reading data from command channel (%1)

We received an exception while trying to read data from the command channel socket. The reason is listed.

CC_REPLY replying to message from '%1' with '%2'

Debug message, noting we're sending a response to the original message with the given envelope.

CC_SET_TIMEOUT setting timeout to %1ms

Debug message. A timeout for which the program is willing to wait for a reply is being set.

CC_START_READ starting asynchronous read

Debug message. From now on, when a message (or command) comes, it'll wake the program and the library will automatically pass it over to correct place.

CC_SUBSCRIBE subscribing to communication group %1

Debug message. The program wants to receive messages addressed to this group.

CC_TIMEOUT timeout reading data from command channel

The program waited too long for data from the command channel (usually when it sent a query to different program and it didn't answer for whatever reason).

CC_UNSUBSCRIBE unsubscribing from communication group %1

Debug message. The program no longer wants to receive messages addressed to this group.

CC_WRITE_ERROR error writing data to command channel (%1)

A low level error happened when the library tried to write data to the command channel socket.

CC_ZERO_LENGTH invalid message length (0)

The library received a message length being zero, which makes no sense, since all messages must contain at least the envelope.

CONFIG_CCSESSION_MSG error in CC session message: %1

There was a problem with an incoming message on the command and control channel. The message does not appear to be a valid command, and is missing a required element or contains an unknown data format. This most likely means that another Kea module is sending a bad message. The message itself is ignored by this module.

CONFIG_CCSESSION_MSG_INTERNAL error handling CC session message: %1

There was an internal problem handling an incoming message on the command and control channel. An unexpected exception was thrown, details of which are appended to the message. The module will continue to run, but will not send back an answer.

The most likely cause of this error is a programming error. Please raise a bug report.

CONFIG_CCSESSION_STOPPING error sending stopping message: %1

There was a problem when sending a message signaling that the module using this CCSession is stopping. This message is sent so that the rest of the system is aware that the module is no longer running. Apart from logging this message, the error itself is ignored, and the ModuleCCSession is still stopped. The specific exception message is printed.

CONFIG_CCSESSION_STOPPING_UNKNOWN unknown error sending stopping message

Similar to CONFIG_CCSESSION_STOPPING, but in this case the exception that is seen is not a standard exception, and further information is unknown. This is a bug.

CONFIG_GET_FAIL error getting configuration from cfgmgr: %1

The configuration manager returned an error when this module requested the configuration. The full error message answer from the configuration manager is appended to the log error. The most likely cause is that the module is of a different (command specification) version than the running configuration manager.

CONFIG_JSON_PARSE JSON parse error in %1: %2

There was an error parsing the JSON file. The given file does not appear to be in valid JSON format. Please verify that the filename is correct and that the contents are valid JSON.

CONFIG_LOG_EXPLICIT will use logging configuration for explicitly-named logger %1

This is a debug message. When processing the "loggers" part of the configuration file, the configuration library found an entry for the named logger that matches the logger specification for the program. The logging configuration for the program will be updated with the information.

CONFIG_LOG_IGNORE_EXPLICIT ignoring logging configuration for explicitly-named logger %1

This is a debug message. When processing the "loggers" part of the configuration file, the configuration library found an entry for the named logger. As this does not match the logger specification for the program, it has been ignored.

CONFIG_LOG_IGNORE_WILD ignoring logging configuration for wildcard logger %1

This is a debug message. When processing the "loggers" part of the configuration file, the configuration library found the named wildcard entry (one containing the "*" character) that matched a logger already matched by an explicitly named entry. The configuration is ignored.

CONFIG_LOG_WILD_MATCH will use logging configuration for wildcard logger %1

This is a debug message. When processing the "loggers" part of the configuration file, the configuration library found the named wildcard entry (one containing the "*" character) that matches a logger specification in the program. The logging configuration for the program will be updated with the information.

CONFIG_MOD_SPEC_FORMAT module specification error in %1: %2

The given file does not appear to be a valid specification file: details are included in the message. Please verify that the filename is correct and that its contents are a valid Kea module specification.

CONFIG_MOD_SPEC_REJECT module specification rejected by cfgmgr: %1

The specification file for this module was rejected by the configuration manager. The full error message answer from the configuration manager is appended to the log error. The most likely cause is that the module is of a different (specification file) version than the running configuration manager.

CONFIG_OPEN_FAIL error opening %1: %2

There was an error opening the given file. The reason for the failure is included in the message.

CONFIG_RPC_SEQ RPC call %1 to %2 with seq %3

Debug message, saying there's a RPC call of given command to given module. It has internal sequence number as listed in the message.

This critical error message indicates that the initial application configuration has failed. The service will start, but will not process requests until the configuration has been corrected.

DCTL_CONFIG_START parsing new configuration: %1

A debug message indicating that the application process has received an updated configuration and has passed it to its configuration manager for parsing.

DCTL_CONFIG_STUB %1 configuration stub handler called

This debug message is issued when the dummy handler for configuration events is called. This only happens during initial startup.

DCTL_CONFIG_UPDATE %1 updated configuration received: %2

A debug message indicating that the controller has received an updated configuration from the Kea configuration system.

DCTL_DISCONNECT_FAIL %1 controller failed to end session with Bundy: %2

This message indicates that while shutting down, the DHCP-DDNS controller encountered an error terminating communication with the Bundy configuration system. The service will still exit. While theoretically possible, this situation is rather unlikely.

DCTL_INIT_PROCESS %1 initializing the application

This debug message is issued just before the controller attempts to create and initialize its application instance.

DCTL_INIT_PROCESS_FAIL %1 application initialization failed: %2

This error message is issued if the controller could not initialize the application and will exit.

DCTL_NOT_RUNNING %1 application instance is not running

A warning message is issued when an attempt is made to shut down the application when it is not running.

DCTL_PARSER_FAIL : %1

On receipt of a new configuration, the server failed to create a parser to decode the contents of the named configuration element, or the creation succeeded but the parsing actions and committal of changes failed. The reason for the failure is given in the message.

DCTL_PROCESS_FAILED %1 application execution failed: %2

The controller has encountered a fatal error while running the application and is terminating. The reason for the failure is included in the message.

DCTL_RUN_PROCESS %1 starting application event loop

This debug message is issued just before the controller invokes the application run method.

DCTL_SESSION_FAIL %1 controller failed to establish Kea session: %1

The controller has failed to establish communication with the rest of Kea and will exit.

DCTL_STANDALONE %1 skipping message queue, running standalone

This is a debug message indicating that the controller is running in the application in standalone mode. This means it will not connected to the Kea message queue. Standalone mode is only useful during program development, and should not be used in a production environment.

DHCP4_ACTIVATE_INTERFACE activating interface %1

This message is printed when DHCPv4 server enabled an interface to be used to receive DHCPv4 traffic. IPv4 socket on this interface will be opened once Interface Manager starts up procedure of opening sockets.

DHCP4_CCSESSION_STARTED control channel session started on socket %1

A debug message issued during startup after the DHCPv4 server has successfully established a session with the Kea control channel.

DHCP4_CCSESSION_STARTING starting control channel session, specfile: %1

This debug message is issued just before the DHCPv4 server attempts to establish a session with the Kea control channel.

DHCP4_CLASS_ASSIGNED client packet has been assigned to the following class(es): %1

This debug message informs that incoming packet has been assigned to specified class or classes. This is a normal behavior and indicates successful operation.

DHCP4_CLASS_PROCESSING_FAILED client class specific processing failed

This debug message means that the server processing that is unique for each client class has reported a failure. The response packet will not be sent.

DHCP4_CLIENT_NAME_PROC_FAIL failed to process the fqdn or hostname sent by a client: %1

This debug message is issued when the DHCP server was unable to process the FQDN or Hostname option sent by a client. This is likely because the client's name was malformed or due to internal server error.

DHCP4_COMMAND_RECEIVED received command %1, arguments: %2

A debug message listing the command (and possible arguments) received from the Kea control system by the DHCPv4 server.

DHCP4_CONFIG_COMPLETE DHCPv4 server has completed configuration: %1

This is an informational message announcing the successful processing of a new configuration. It is output during server startup, and when an updated configuration is committed by the administrator. Additional information may be provided.

DHCP4_CONFIG_LOAD_FAIL configuration error using file: %1, reason: %2

This error message indicates that the DHCPv4 configuration has failed. If this is an initial configuration (during server's startup) the server will fail to start. If this is a dynamic reconfiguration attempt the server will continue to use an old configuration.

DHCP4_CONFIG_NEW_SUBNET a new subnet has been added to configuration: %1

This is an informational message reporting that the configuration has been extended to include the specified IPv4 subnet.

DHCP4_CONFIG_OPTION_DUPLICATE multiple options with the code %1 added to the subnet %2

This warning message is issued on an attempt to configure multiple options with the same option code for a particular subnet. Adding multiple options is uncommon for DHCPv4, but is not prohibited.

DHCP4_CONFIG_RECEIVED received configuration %1

A debug message listing the configuration received by the DHCPv4 server. The source of that configuration depends on used configuration backend.

DHCP4_CONFIG_START DHCPv4 server is processing the following configuration: %1

This is a debug message that is issued every time the server receives a configuration. That happens at start up and also when a server configuration change is committed by the administrator.

DHCP4_CONFIG_UPDATE updated configuration received: %1

A debug message indicating that the DHCPv4 server has received an updated configuration from the Kea configuration system.

DHCP4_DDNS_REQUEST_SEND_FAILED failed sending a request to kea-dhcp-ddns, error: %1, ncr: %2

This error message indicates that DHCP4 server attempted to send a DDNS update request to the DHCP-DDNS server. This is most likely a configuration or networking error.

DHCP4_DEACTIVATE_INTERFACE deactivate interface %1

This message is printed when DHCPv4 server disables an interface from being used to receive DHCPv4 traffic. Sockets on this interface will not be opened by the Interface Manager until interface is enabled.

DHCP4_DHCID_COMPUTE_ERROR failed to compute the DHCID for lease: %1, reason: %2

This error message is logged when the attempt to compute DHCID for a specified lease has failed. The lease details and reason for failure is logged in the message.

DHCP4_DYNAMIC_RECONFIGURATION initiate server reconfiguration using file: %1, after receiving SIGHUP signal

This is the info message logged when the DHCPv4 server starts reconfiguration as a result of receiving SIGHUP signal.

DHCP4_DYNAMIC_RECONFIGURATION_FAIL dynamic server reconfiguration failed with file: %1

This is an error message logged when the dynamic reconfiguration of the DHCP server failed.

DHCP4_EMPTY_HOSTNAME received empty hostname from the client, skipping processing of this option

This debug message is issued when the server received an empty Hostname option from a client. Server does not process empty Hostname options and therefore option is skipped.

DHCP4_HOOKS_LIBS_RELOAD_FAIL reload of hooks libraries failed

A "libreload" command was issued to reload the hooks libraries but for some reason the reload failed. Other error messages issued from the hooks framework will indicate the nature of the problem.

DHCP4_HOOK_BUFFER_RCVD_SKIP received DHCPv4 buffer was dropped because a callout set the skip flag.

This debug message is printed when a callout installed on buffer4_receive hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to drop the packet.

DHCP4_HOOK_BUFFER_SEND_SKIP prepared DHCPv4 response was dropped because a callout set the skip flag.

This debug message is printed when a callout installed on buffer4_send hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to drop the packet. Server completed all the processing (e.g. may have assigned, updated or released leases), but the response will not be send to the client.

DHCP4_HOOK_LEASE4_RELEASE_SKIP DHCPv4 lease was not released because a callout set the skip flag.

This debug message is printed when a callout installed on lease4_release hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to not release a lease.

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.

DHCP4_INIT_FAIL failed to initialize Kea server: %1

The server has failed to initialize. This may be because the configuration was not successful, or it encountered any other critical error on startup. Attached error message provides more details about the issue.

DHCP4_INVALID_ADDRESS_INIT_REBOOT invalid address %1 requested by INIT-REBOOT client (id: %2, hwaddr: %3)

This debug message is issued when the client being in the INIT-REBOOT state requested an address which is not assigned to him. The server will respond to this client with DHCPNAK.

DHCP4_INVALID_RELAY_INFO malformed packet received from client-id %1, hwaddr %2: %3

This message is logged when the client sends invalid combination of values in the giaddr and hops fields. If the packet is relayed it should contain non-zero values in both fields. If the packet is sent from the directly connected client, both values should be set to zero. All other combinations are invalid and trigger packet drop.

DHCP4_LEASE_ADVERT lease %1 advertised (client client-id %2, hwaddr %3)

This debug message indicates that the server successfully advertised a lease. It is up to the client to choose one server out of other advertised and continue allocation with that server. This is a normal behavior and indicates successful operation.

DHCP4_LEASE_ADVERT_FAIL failed to advertise a lease for client client-id %1, hwaddr %2, client sent yiaddr %3

This message indicates that the server has failed to offer a lease to the specified client after receiving a DISCOVER message from it. There are many possible reasons for such a failure.

DHCP4_LEASE_ALLOC lease %1 has been allocated for client-id %2, hwaddr %3

This debug message indicates that the server successfully granted a lease in response to client's REQUEST message. This is a normal behavior and indicates successful operation.

DHCP4_LEASE_ALLOC_FAIL failed to grant a lease for client-id %1, hwaddr %2, client sent yiaddr %3

This message indicates that the server failed to grant a lease to the specified client after receiving a REQUEST message from it. There are many possible reasons for such a failure. Additional messages will indicate the reason.

DHCP4_LEASE_DATABASE_TIMERS_EXEC_FAIL failed to execute timer-based functions for lease database: %1

A warning message executed when a server process is unable to execute the periodic actions for the lease database. An example of the periodic action is a Lease File Cleanup. One of the reasons for the failure is a misconfiguration of the lease database, whereby the lease database hasn't been selected.

DHCP4_NAME_GEN_UPDATE_FAIL failed to update the lease after generating name for a client: %1

This message indicates the failure when trying to update the lease and/or options in the server's response with the hostname generated by the server from the acquired address. The message argument indicates the reason for the failure.

DHCP4_NCR_CREATION_FAILED failed to generate name change requests for DNS: %1

This message indicates that server was unable to generate NameChangeRequests which should be sent to the kea-dhcp_ddns module to create new DNS records for the lease being acquired or to update existing records for the renewed lease. The reason for the failure is printed in the logged message.

DHCP4_NOT_RUNNING DHCPv4 server is not running

A warning message is issued when an attempt is made to shut down the DHCPv4 server but it is not running.

DHCP4_NO_LEASE_INIT_REBOOT no lease for address %1 requested by INIT-REBOOT client (id: %2, hwaddr: %3)

This debug message is issued when the client being in the INIT-REBOOT state requested an address but this client is unknown. The server will not respond.

DHCP4_NO_SOCKETS_OPEN no interface configured to listen to DHCP traffic

This warning message is issued when current server configuration specifies no interfaces that server should listen on, or specified interfaces are not configured to receive the traffic.

DHCP4_NO_SUBNET_FOR_DIRECT_CLIENT no suitable subnet configured for a direct client sending packet with transaction id %1, on interface %2, received message is dropped

This info message is logged when received a message from a directly connected client but there is no suitable subnet configured for the interface on which this message has been received. The IPv4 address assigned on this interface must belong to one of the configured subnets. Otherwise received message is dropped.

DHCP4_OPEN_SOCKET opening sockets on port %1

A debug message issued during startup, this indicates that the DHCPv4 server is about to open sockets on the specified port.

DHCP4_OPEN_SOCKET_FAIL failed to open socket: %1

A warning message issued when IfaceMgr fails to open and bind a socket. The reason for the failure is appended as an argument of the log message.

DHCP4_PACKET_DROP_NO_TYPE packet received on interface %1 dropped, because of missing msg-type option

This is a debug message informing that incoming DHCPv4 packet did not have mandatory DHCP message type option and thus was dropped.

DHCP4_PACKET_NOT_FOR_US received DHCPv4 message (transid=%1, iface=%2) dropped because it contains foreign server identifier

This debug message is issued when received DHCPv4 message is dropped because it is addressed to a different server, i.e. a server identifier held by this message doesn't match the identifier used by our server. The arguments of this message hold the name of the transaction id and interface on which the message has been received.

DHCP4_PACKET_PARSE_FAIL failed to parse incoming packet: %1

The DHCPv4 server has received a packet that it is unable to interpret. The reason why the packet is invalid is included in the message.

DHCP4_PACKET_PROCESS_FAIL failed to process packet received from %1: %2

DHCP6_EXTEND_LEASE_SUBNET_SELECT_FAILED failed to select a subnet for received %1: src=%2 type=%3

This warning message is output when a Renew or Rebind was received from a subnet for which the DHCPv6 server has not been configured. The cause is most likely due to a misconfiguration of the server. The packet processing will continue, but the response will only contain generic configuration parameters and no addresses or prefixes.

DHCP6_EXTEND_NA_UNKNOWN received unknown IA_NA from client (duid=%1, iaid=%2) in subnet %3

This warning message is printed when client attempts to extend the lease for the address (in the IA_NA option) but no such lease is known by the server. It typically means that client has attempted to use its lease past its lifetime: causes of this include a adjustment of the client's date/time setting or poor support on the client for sleep/recovery. A properly implemented client will recover from such a situation by restarting the lease allocation process after receiving a negative reply from the server.

An alternative cause could be that the server has lost its database recently and does not recognize its well-behaving clients. This is more probable if you see many such messages. Clients will recover from this, but they will most likely get a different IP addresses and experience a brief service interruption.

DHCP6_EXTEND_NA_UNKNOWN_SUBNET %1 message received from client on unknown subnet (duid=%2, iaid=%3)

A warning message indicating that a client is attempting to extend lease lifetime for the address, but the server does not have any information about the subnet this client belongs to. This may mean that faulty the mobile client changed its location and is trying to renew its old address (client is supposed to send confirm, not renew in such cases, according to RFC3315) or the server configuration has changed and information about existing subnet was removed. Note that in a sense this is worse case of DHCP6_EXTEND_NA_UNKNOWN, as not only the lease is unknown, but also the subnet is. Depending on the reasons of this condition, it may or may not correct on its own.

DHCP6_EXTEND_PD_NO_BINDING client sent a %1 message to extend lifetimes of prefixes for an unknown binding: duid=%2, iaid=%3, subnet=%4

This warning message is logged when a client attempts to extend the lifetime of the prefix it is using, but the server was unable to find the binding to which this lease belongs. This error condition has different implications for the Renew and Rebind messages. For the former, the server will respond with NoBinding status code. For the latter, the server will discard the message.

DHCP6_EXTEND_PD_UNKNOWN_SUBNET %1 message received from client on unknown subnet (duid=%2, iaid=%3)

A warning message indicating that a client is attempting to extend lease lifetime for the prefix, but the server doesn't have any information about the subnet this client belongs to.

DHCP6_HOOK_BUFFER_SEND_SKIP prepared DHCPv6 response was dropped because a callout set the skip flag

This debug message is printed when a callout installed on buffer6_send hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to drop the packet. Server completed all the processing (e.g. may have assigned, updated or released leases), but the response will not be send to the client.

DHCP6_HOOK_LEASE6_EXTEND_SKIP DHCPv6 lease lifetime was not extended because a callout set the skip flag for message %1

or lease6_rebind hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to not extend the lifetime for a lease. If client requested renewal of multiples leases (by sending multiple IA options), the server will skip the renewal of the one in question and will proceed with other renewals as usual.

DHCP6_HOOK_LEASE6_RELEASE_NA_SKIP DHCPv6 address lease was not released because a callout set the skip flag

This debug message is printed when a callout installed on the lease6_release hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to not release a lease. If a client requested the release of multiples leases (by sending multiple IA options), the server will retain this particular lease and proceed with other releases as usual.

DHCP6_HOOK_LEASE6_RELEASE_PD_SKIP DHCPv6 prefix lease was not released because a callout set the skip flag

This debug message is printed when a callout installed on lease6_release hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to not release a lease. If client requested release of multiples leases (by sending multiple IA options), the server will retains this particular lease and will proceed with other renewals as usual.

DHCP6_HOOK_LEASE6_RENEW_SKIP DHCPv6 lease was not renewed because a callout set the skip flag

This debug message is printed when a callout installed on lease6_renew hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to not renew a lease. If client requested renewal of multiples leases (by sending multiple IA options), the server will skip the renewal of the one in question and will proceed with other renewals as usual.

DHCP6_HOOK_PACKET_RCVD_SKIP received DHCPv6 packet was dropped because a callout set the skip flag

This debug message is printed when a callout installed on the pkt6_receive hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to drop the packet.

DHCP6_HOOK_PACKET_SEND_SKIP prepared DHCPv6 response was not sent because a callout set the skip flag

This debug message is printed when a callout installed on the pkt6_send hook point set the skip flag. For this particular hook point, the setting of the flag by a callout instructs the server to drop the packet. This effectively 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).

DHCP6_HOOK_SUBNET6_SELECT_SKIP no subnet was selected because a callout set the skip flag

This debug message is printed when a callout installed on the subnet6_select hook point set 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 or prefixes will be assigned.

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

DHCP6_RELEASE_NA_FAIL failed to remove address lease for address %1 for duid=%2, iaid=%3

This error message indicates that the software failed to remove an address lease from the lease database. It 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.

DHCP6_RELEASE_NA_FAIL_WRONG_DUID client (duid=%1) tried to release address %2, but it belongs to another client (duid=%3)

This warning message indicates that a 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.

DHCP6_RELEASE_NA_FAIL_WRONG_IAID client (duid=%1) tried to release address %2, but it used wrong IAID (expected %3, but got %4)

This warning message indicates that client tried to release an address that does belong to it, but the address was expected to be in a different IA (identity association) container. This probably means that the client's support for multiple addresses is flawed.

It may also be triggered if a lease was manually removed from the database during RELEASE message processing.

DHCP6_RELEASE_PD_FAIL_WRONG_DUID client (duid=%1) tried to release prefix %2, but it belongs to another client (duid=%3)

This warning message indicates that client tried to release a prefix 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 prefix will stop using it anyway, there is a good chance that the situation will correct itself.

DHCP6_RELEASE_PD_FAIL_WRONG_IAID client (duid=%1) tried to release prefix %2, but it used wrong IAID (expected %3, but got %4)

This warning message indicates that client tried to release a prefix that does belong to it, but the address was expected to be in a different IA (identity association) container. This probably means that the client's support for multiple prefixes is flawed.

DHCP6_REQUIRED_OPTIONS_CHECK_FAIL %1 message received from %2 failed the following check: %3

This message indicates that received DHCPv6 packet is invalid. This may be due to a number of reasons, e.g. the mandatory client-id option is missing, the server-id forbidden in that particular type of message is present, there is more than one instance of client-id or server-id present, etc. The exact reason for rejecting the packet is included in the message.

Kea has failed to close the named hook library for the stated reason. Although this is an error, this should not affect the running system other than as a loss of resources. If this error persists, you should restart Kea.

HOOKS_HOOK_LIST_RESET the list of hooks has been reset

This is a message indicating that the list of hooks has been reset. While this is usual when running the Kea test suite, it should not be seen when running Kea in a production environment. If this appears, please report a bug through the usual channels.

HOOKS_INCORRECT_VERSION hook library %1 is at version %2, require version %3

Kea has detected that the named hook library has been built against a version of Kea that is incompatible with the version of Kea running on your system. It has not loaded the library.

This is most likely due to the installation of a new version of Kea without rebuilding the hook library. A rebuild and re-install of the library should fix the problem in most cases.

HOOKS_LIBRARY_LOADED hooks library %1 successfully loaded

This information message is issued when a user-supplied hooks library has been successfully loaded.

HOOKS_LIBRARY_LOADING loading hooks library %1

This is a debug message output just before the specified library is loaded. If the action is successfully, it will be followed by the HOOKS_LIBRARY_LOADED informational message.

HOOKS_LIBRARY_UNLOADED hooks library %1 successfully unloaded

This information message is issued when a user-supplied hooks library has been successfully unloaded.

HOOKS_LIBRARY_UNLOADING unloading library %1

This is a debug message called when the specified library is being unloaded. If all is successful, it will be followed by the HOOKS_LIBRARY_UNLOADED informational message.

HOOKS_LIBRARY_VERSION hooks library %1 reports its version as %2

A debug message issued when the version check on the hooks library has succeeded.

HOOKS_LOAD_ERROR 'load' function in hook library %1 returned error %2

A "load" function was found in the library named in the message and was called. The function returned a non-zero status (also given in the message) which was interpreted as an error. The library has been unloaded and no callouts from it will be installed.

HOOKS_LOAD_EXCEPTION 'load' function in hook library %1 threw an exception

A "load" function was found in the library named in the message and was called. The function threw an exception (an error indication) during execution, which is an error condition. The library has been unloaded and no callouts from it will be installed.

HOOKS_LOAD_FRAMEWORK_EXCEPTION 'load' function in hook library %1 threw an exception: reason %2

A "load" function was found in the library named in the message and was called. Either the hooks framework or the function threw an exception (an error indication) during execution, which is an error condition; the cause of the exception is recorded in the message. The library has been unloaded and no callouts from it will be installed.

HOOKS_LOAD_SUCCESS 'load' function in hook library %1 returned success

This is a debug message issued when the "load" function has been found in a hook library and has been successfully called.

HOOKS_NO_LOAD no 'load' function found in hook library %1

This is a debug message saying that the specified library was loaded but no function called "load" was found in it. Providing the library contained some "standard" functions (i.e. functions with the names of the hooks for the given server), this is not an issue.

HOOKS_NO_UNLOAD no 'unload' function found in hook library %1

This is a debug message issued when the library is being unloaded. It merely states that the library did not contain an "unload" function.

HOOKS_NO_VERSION no 'version' function found in hook library %1

The shared library named in the message was found and successfully loaded, but Kea did not find a function named "version" in it. This function is required and should return the version of Kea against which the library was built. The value is used to check that the library was built against a compatible version of Kea. The library has not been loaded.

HOOKS_OPEN_ERROR failed to open hook library %1: %2

Kea failed to open the specified hook library for the stated reason. The library has not been loaded. Kea will continue to function, but without the services offered by the library.

HOOKS_STD_CALLOUT_REGISTERED hooks library %1 registered standard callout for hook %2 at address %3

This is a debug message, output when the library loading function has located a standard callout (a callout with the same name as a hook point) and registered it. The address of the callout is indicated.

HOOKS_UNLOAD_ERROR 'unload' function in hook library %1 returned error %2

During the unloading of a library, an "unload" function was found. It was called, but returned an error (non-zero) status, resulting in the issuing of this message. The unload process continued after this message and the library has been unloaded.

HOOKS_UNLOAD_EXCEPTION 'unload' function in hook library %1 threw an exception

During the unloading of a library, an "unload" function was found. It was called, but in the process generated an exception (an error indication). The unload process continued after this message and the library has been unloaded.

HOOKS_UNLOAD_FRAMEWORK_EXCEPTION 'unload' function in hook library %1 threw an exception, reason %2

During the unloading of a library, an "unload" function was found. It was called, but in the process either it or the hooks framework generated an exception (an error indication); the cause of the error is recorded in the message. The unload process continued after this message and the library has been unloaded.

HOOKS_UNLOAD_SUCCESS 'unload' function in hook library %1 returned success

This is a debug message issued when an "unload" function has been found in a hook library during the unload process, called, and returned success.

HOOKS_VERSION_EXCEPTION 'version' function in hook library %1 threw an exception

This error message is issued if the version() function in the specified hooks library was called and generated an exception. The library is considered unusable and will not be loaded.

LFC_FAIL_PID_CREATE : %1

This message is issued if LFC detected a failure when trying to create the PID file. It includes a more specifc error string.

LFC_FAIL_PID_DEL : %1

This message is issued if LFC detected a failure when trying to delete the PID file. It includes a more specifc error string.

LFC_FAIL_PROCESS : %1

This message is issued if LFC detected a failure when trying to process the files. It includes a more specifc error string.

LFC_FAIL_ROTATE : %1

This message is issued if LFC detected a failure when trying to rotate the files. It includes a more specifc error string.

LFC_PROCESSING Previous file: %1, copy file: %2

This message is issued just before LFC starts processing the lease files.

LFC_READ_STATS Leases: %1, attempts: %2, errors: %3.

This message prints out the number of leases that were read, the number of attempts to read leases and the number of errors encountered while reading.

LFC_ROTATING LFC rotating files

This message is issued just before LFC starts rotating the lease files - removing the old and replacing them with the new.

LFC_RUNNING LFC instance already running

This message is issued if LFC detects that a previous copy of LFC may still be running via the PID check.

LFC_START Starting lease file cleanup

This message is issued as the LFC process starts.

LFC_TERMINATE LFC finished processing

This message is issued when the LFC process completes. It does not indicate that the process was successful only that it has finished.

LFC_WRITE_STATS Leases: %1, attempts: %2, errors: %3.

This message prints out the number of leases that were written, the number of attempts to write leases and the number of errors encountered while writing.

LOGIMPL_ABOVE_MAX_DEBUG debug level of %1 is too high and will be set to the maximum of %2

A message from the interface to the underlying logger implementation reporting that the debug level (as set by an internally-created string DEBUGn, where n is an integer, e.g. DEBUG22) is above the maximum allowed value and has been reduced to that value. The appearance of this message may indicate a programming error - please submit a bug report.

LOGIMPL_BAD_DEBUG_STRING debug string '%1' has invalid format

A message from the interface to the underlying logger implementation reporting that an internally-created string used to set the debug level is not of the correct format (it should be of the form DEBUGn, where n is an integer, e.g. DEBUG22). The appearance of this message indicates a programming error - please submit a bug report.

LOGIMPL_BELOW_MIN_DEBUG debug level of %1 is too low and will be set to the minimum of %2

A message from the interface to the underlying logger implementation reporting that the debug level (as set by an internally-created string DEBUGn, where n is an integer, e.g. DEBUG22) is below the minimum allowed value and has been increased to that value. The appearance of this message may indicate a programming error - please submit a bug report.

LOG_BAD_DESTINATION unrecognized log destination: %1

A logger destination value was given that was not recognized. The destination should be one of "console", "file", or "syslog".

LOG_BAD_SEVERITY unrecognized log severity: %1

A logger severity value was given that was not recognized. The severity should be one of "DEBUG", "INFO", "WARN", "ERROR", "FATAL" or "NONE".

LOG_BAD_STREAM bad log console output stream: %1

Logging has been configured so that output is written to the terminal (console) but the stream on which it is to be written is not recognised. Allowed values are "stdout" and "stderr".

LOG_DUPLICATE_MESSAGE_ID duplicate message ID (%1) in compiled code

During start-up, Kea detected that the given message identification had been defined multiple times in the Kea code. This indicates a programming error; please submit a bug report.

LOG_DUPLICATE_NAMESPACE line %1: duplicate $NAMESPACE directive found

When reading a message file, more than one $NAMESPACE directive was found. (This directive is used to set a C++ namespace when generating header files during software development.) Such a condition is regarded as an error and the read will be abandoned.

LOG_INPUT_OPEN_FAIL unable to open message file %1 for input: %2

The program was not able to open the specified input message file for the reason given.

LOG_INVALID_MESSAGE_ID line %1: invalid message identification '%2'

An invalid message identification (ID) has been found during the read of a message file. Message IDs should comprise only alphanumeric characters and the underscore, and should not start with a digit.

LOG_LOCK_TEST_MESSAGE this is a test message.

This is a log message used in testing.

LOG_NAMESPACE_EXTRA_ARGS line %1: $NAMESPACE directive has too many arguments

The $NAMESPACE directive in a message file takes a single argument, a namespace in which all the generated symbol names are placed. This error is generated when the compiler finds a $NAMESPACE directive with more than one argument.

LOG_NAMESPACE_INVALID_ARG line %1: $NAMESPACE directive has an invalid argument ('%2')

The $NAMESPACE argument in a message file should be a valid C++ namespace. This message is output if the simple check on the syntax of the string carried out by the reader fails.

LOG_NAMESPACE_NO_ARGS line %1: no arguments were given to the $NAMESPACE directive

The $NAMESPACE directive in a message file takes a single argument, a C++ namespace in which all the generated symbol names are placed. This error is generated when the compiler finds a $NAMESPACE directive with no arguments.

LOG_NO_MESSAGE_ID line %1: message definition line found without a message ID

Within a message file, message are defined by lines starting with a "%". The rest of the line should comprise the message ID and text describing the message. This error indicates the message compiler found a line in the message file comprising just the "%" and nothing else.

LOG_NO_MESSAGE_TEXT line %1: line found containing a message ID ('%2') and no text

Within a message file, message are defined by lines starting with a "%". The rest of the line should comprise the message ID and text describing the message. This error indicates the message compiler found a line in the message file comprising just the "%" and message identification, but no text.

LOG_NO_SUCH_MESSAGE could not replace message text for '%1': no such message

During start-up a local message file was read. A line with the listed message identification was found in the file, but the identification is not one contained in the compiled-in message dictionary. This message may appear a number of times in the file, once for every such unknown message identification.

There may be several reasons why this message may appear:

- The message ID has been mis-spelled in the local message file.

- The program outputting the message may not use that particular message (e.g. it originates in a module not used by the program).

- The local file was written for an earlier version of the Kea software and the later version no longer generates that message.

Whatever the reason, there is no impact on the operation of Kea.

LOG_OPEN_OUTPUT_FAIL unable to open %1 for output: %2

Originating within the logging code, the program was not able to open the specified output file for the reason given.

LOG_PREFIX_EXTRA_ARGS line %1: $PREFIX directive has too many arguments

Within a message file, the $PREFIX directive takes a single argument, a prefix to be added to the symbol names when a C++ file is created. This error is generated when the compiler finds a $PREFIX directive with more than one argument.

Note: the $PREFIX directive is deprecated and will be removed in a future version of Kea.

LOG_PREFIX_INVALID_ARG line %1: $PREFIX directive has an invalid argument ('%2')

Within a message file, the $PREFIX directive takes a single argument, a prefix to be added to the symbol names when a C++ file is created. As such, it must adhere to restrictions on C++ symbol names (e.g. may only contain alphanumeric characters or underscores, and may nor start with a digit). A $PREFIX directive was found with an argument (given in the message) that violates those restrictions.

Note: the $PREFIX directive is deprecated and will be removed in a future version of Kea.

LOG_READING_LOCAL_FILE reading local message file %1

This is an informational message output by Kea when it starts to read a local message file. (A local message file may replace the text of one or more messages; the ID of the message will not be changed though.)

LOG_READ_ERROR error reading from message file %1: %2

The specified error was encountered reading from the named message file.

LOG_UNRECOGNISED_DIRECTIVE line %1: unrecognised directive '%2'

Within a message file, a line starting with a dollar symbol was found (indicating the presence of a directive) but the first word on the line (shown in the message) was not recognised.

LOG_WRITE_ERROR error writing to %1: %2

The specified error was encountered by the message compiler when writing to the named output file.

USER_CHK_HOOK_LOAD_ERROR DHCP UserCheckHook could not be loaded: %1

This is an error message issued when the DHCP UserCheckHook could not be loaded. The exact cause should be explained in the log message. User subnet selection will revert to default processing.

USER_CHK_HOOK_UNLOAD_ERROR DHCP UserCheckHook an error occurred unloading the library: %1

This is an error message issued when an error occurs while unloading the UserCheckHook library. This is unlikely to occur and normal operations of the library will likely resume when it is next loaded.

USER_CHK_SUBNET4_SELECT_ERROR DHCP UserCheckHook an unexpected error occurred in subnet4_select callout: %1

This is an error message issued when the DHCP UserCheckHook subnet4_select hook encounters an unexpected error. The message should contain a more detailed explanation.

USER_CHK_SUBNET4_SELECT_REGISTRY_NULL DHCP UserCheckHook UserRegistry has not been created.

This is an error message issued when the DHCP UserCheckHook subnet4_select hook has been invoked but the UserRegistry has not been created. This is a programmatic error and should not occur.

USER_CHK_SUBNET6_SELECT_ERROR DHCP UserCheckHook an unexpected error occurred in subnet6_select callout: %1

This is an error message issued when the DHCP UserCheckHook subnet6_select hook encounters an unexpected error. The message should contain a more detailed explanation.

USER_CHK_SUBNET6_SELECT_REGISTRY_NULL DHCP UserCheckHook UserRegistry has not been created.

This is an error message issued when the DHCP UserCheckHook subnet6_select hook has been invoked but the UserRegistry has not been created. This is a programmatic error and should not occur.
