is the Very Secure File Transfer Protocol Daemon. The server  can
     be  launched  via  a  such  as  or  Alternatively,  vsftpd can be
     launched in standalone mode, in which  case  vsftpd  itself  will
     listen  on  the  network.  This latter mode is easier to use, and
     recommended. It is activated by setting in  Direct  execution  of
     the  binary  will then launch the FTP service ready for immediate
     client connections.  An optional configuration file or files  may
     be  given  on the command line. These files must be owned as root
     if running as root. Any command line option not starting  with  a
     "-"  character  is  treated as a config file that will be loaded.
     Note that config files are loaded in the strict order  that  they
     are  encountered  on  the  command  line.  If no config files are
     specified, the default configuration  file  of  will  be  loaded,
     after  all  other  command line options are processed.  Supported
     options are: Print the version  information  and  exit,  even  if
     other  options  are encountered.  Set a single option, value pair
     as per the format in the config file.  Multiple  -o  options  are
     supported, and they are applied in strict order relative to their
     appearance on the  command  line,  including  intermingling  with
     loading  of  config  files.   vsftpd -olisten=NO /etc/vsftpd.conf
     -oftpd_banner=blah  That  example  overrides  vsftpd's   built-in
     default  for  the  "listen"  option  to  be  NO,  but  then loads
     /etc/vsftpd.conf which may override that  setting.  Finally,  the
     "ftpd_banner"  setting  is  set  to  "blah",  which overrides any
     default vsftpd setting and any identical setting that was in  the
     config file.
