  - fw log :
  -         -f select current log file
  -         -t tail file
  -         -n use ip instead of name
  -         -p use port number instead of name

  -            Use of -l changes log format slightly
  -
  -         -g without : and ; delimiters
  -            use of -g significantly changes log format
  -            this decoder is incompatible with -g
