+ * where the fields are (note that the client sends requests, the server
+ * responses):
+ *
+ * Response Bit: This packet is a response (if clear, packet is a request).
+ *
+ * More Bit: Set for all packets but the last in a response which
+ * requires more than one packet.
+ *
+ * Version Number: 2 for current version
+ *
+ * Mode: Always 7
+ *
+ * Authenticated bit: If set, this packet is authenticated.
+ *
+ * Sequence number: For a multipacket response, contains the sequence
+ * number of this packet. 0 is the first in the sequence,
+ * 127 (or less) is the last. The More Bit must be set in
+ * all packets but the last.
+ *
+ * Implementation number: The number of the implementation this request code
+ * is defined by. An implementation number of zero is used
+ * for requst codes/data formats which all implementations
+ * agree on. Implementation number 255 is reserved (for
+ * extensions, in case we run out).
+ *
+ * Request code: An implementation-specific code which specifies the
+ * operation to be (which has been) performed and/or the
+ * format and semantics of the data included in the packet.
+ *
+ * Err: Must be 0 for a request. For a response, holds an error
+ * code relating to the request. If nonzero, the operation
+ * requested wasn't performed.
+ *
+ * 0 - no error
+ * 1 - incompatable implementation number
+ * 2 - unimplemented request code
+ * 3 - format error (wrong data items, data size, packet size etc.)
+ * 4 - no data available (e.g. request for details on unknown peer)
+ * 5-6 I don't know
+ * 7 - authentication failure (i.e. permission denied)
+ *
+ * Number of data items: number of data items in packet. 0 to 500
+ *
+ * MBZ: A reserved data field, must be zero in requests and responses.
+ *
+ * Size of data item: size of each data item in packet. 0 to 500
+ *
+ * Data: Variable sized area containing request/response data. For
+ * requests and responses the size in octets must be greater
+ * than or equal to the product of the number of data items
+ * and the size of a data item. For requests the data area
+ * must be exactly 40 octets in length. For responses the
+ * data area may be any length between 0 and 500 octets
+ * inclusive.
+ *
+ * Message Authentication Code: Same as NTP spec, in definition and function.
+ * May optionally be included in requests which require
+ * authentication, is never included in responses.
+ *
+ * The version number, mode and keyid have the same function and are
+ * in the same location as a standard NTP packet. The request packet
+ * is the same size as a standard NTP packet to ease receive buffer
+ * management, and to allow the same encryption procedure to be used
+ * both on mode 7 and standard NTP packets. The mac is included when
+ * it is required that a request be authenticated, the keyid should be
+ * zero in requests in which the mac is not included.
+ *
+ * The data format depends on the implementation number/request code pair
+ * and whether the packet is a request or a response. The only requirement
+ * is that data items start in the octet immediately following the size
+ * word and that data items be concatenated without padding between (i.e.
+ * if the data area is larger than data_items*size, all padding is at
+ * the end). Padding is ignored, other than for encryption purposes.
+ * Implementations using encryption might want to include a time stamp
+ * or other data in the request packet padding. The key used for requests
+ * is implementation defined, but key 15 is suggested as a default.
