This document, current as of TftpdNT v1.3, describes all of the log file
entries which TftpdNT can produce.  Each log file entry is preceeded by a
timestamp including the date, time and the thread id.
----------

LEVEL 1 CONDITION
TftpdNT was unable to initialise or condition the network socket (fatal)

LOGFILE ENTRIES
Aborting on create socket
Aborting on bind socket
Aborting on define timeout for socket
----------

LEVEL 6 CONDITION
TftpdNT was unable to initialise or condition the network socket (fatal)

LOGFILE ENTRY
Aborting on create socket
Aborting on bind socket
----------

LEVEL 0 CONDITION
TftpdNT was unable to determine which port to use.  Your "services" file,
which should reside in one of the Windows directories, has no entry for
tftp.  This is an operating system problem. (fatal)

LOGFILE ENTRY
tftp: udp/tftp: unknown service
----------

LEVEL 1 CONDITION
Connection established with client but TftpdNT was unable to determine its
hostname.  This may indicate a misconfigured DNS (No in-addr.arpa entry
for the ip address) which can only be corrected by the organisation that
administers the TFTP client host. (warning)

LOGFILE ENTRY
Cannot obtain client hostname (<ip address>)
----------

LEVEL 1 CONDITION
Connction established with client (information)

LOGFILE ENTRY
Client: <name> (<ip address>)
----------

LEVEL 9 CONDITION
Dump of received packet (diagnostic)

LOGFILE ENTRY
Packet dump: <hex output>
----------

LEVEL 1 CONDITION
The TFTP client reported some error (information)

LOGFILE ENTRY
ERROR message from client site:'<text of error>'
Error Message: '<text of error>'
----------

LEVEL 1 CONDITION
A malformed TFTP message was sent by the TFTP client.  This indicates a
problem with the TFTP client. (warning)

LOGFILE ENTRY
Packet dump: <hex output>
----------

LEVEL 1 CONDITION
An incoming TFTP request has been received. (information)

LOGFILE ENTRIES
Read request. File name: '<filename>' Mode: 'netascii'
Read request. File name: '<filename>' Mode: 'octet'
Write request. File name: '<filename>' Mode: 'netascii'
Write request. File name: '<filename>' Mode: 'octet'
----------

LEVEL 1 CONDITION
Unable to send data to, or receive from, TFTP client.  This could be a
network problem, but is more likely to be an operating system problem.
(aborts current transmission)

LOGFILE ENTRIES
Sendto Error.  LastError=<number>, LastSockError=<number>
Recvfrom Error.  LastError=<number>, LastSockError=<number>
----------

LEVEL 9 CONDITION
Sent data to, or received data from, TFTP client. (information)

LOGFILE ENTRY
Sent DATA Block=<block number>, <number> bytes
Received DATA Block=<block number>, <number> bytes
----------

LEVEL 9 CONDITION
Packet acknowledgement (information)

LOGFILE ENTRY
Received ACK Block=<block number>
Sent ACK Block=<block number>
----------

LEVEL 6 CONDITION
An acknowledgement has been received for a different data block than
expected.  TftpdNT resynchronises based on the acknowledged block. (warning)

LOGFILE ENTRY
Re-synchronize. Sent 'DATA' Block=<block number>. Received 'ACK' Block=<block number>
Re-synchronize. Received 'DATA' Block=<block number>. Received 'ACK' Block=<block number>
----------

LEVEL 1 CONDITION
File transmission complete (information)

LOGFILE ENTRY
File has been sent. <number> bytes (<number> blocks)
File has been received. <number> bytes (<number> blocks)
----------

LEVEL 1 CONDITION
A packet has been sent five times without being acknowledged by the client.
(aborts current transmission)

LOGFILE ENTRY
Total transmission timeout. Aborted sending file
----------

LEVEL 2 CONDITION
A packet that was sent has not been acknowledged by the client within the
timeout period (defaults to five seconds.) (warning)

LOGFILE ENTRY
Per-packet retransmission timeout
----------

LEVEL 1 CONDITION
Unable to set the timeout for socket receives.  This message occurs when
transmission has completed (or already been aborted) and so is a warning
despite indicating an serious problem (probably at the operating system)
(aborts current transmission)

LOGFILE ENTRY
Aborting on define infinite timeout for socket
----------

LEVEL 1 CONDITION
Error sending negative acknowledgement to client.  Probably due to a
network or operating system problem. (warning)

LOGFILE ENTRY
Nak Error.  LastError=<number>, LastSockError=<number>
----------

LEVEL 6 CONDITION
