NAME

       vsftpd.conf - config file for vsftpd

DESCRIPTION

       vsftpd.conf  may  be  used  to  control  various  aspects  of  vsftpd’s
       behaviour. By default, vsftpd looks  for  this  file  at  the  location
       /etc/vsftpd.conf.   However,  you  may  override  this  by specifying a
       command line argument to vsftpd.  The  command  line  argument  is  the
       pathname of the configuration file for vsftpd. This behaviour is useful
       because you may wish to use an advanced inetd such as xinetd to  launch
       vsftpd  with different configuration files on a per virtual host basis.

FORMAT

       The format of vsftpd.conf is very simple. Each line is either a comment
       or  a  directive.  Comment  lines  start  with  a  # and are ignored. A
       directive line has the format:

       option=value

       It is important to note that it is an error to put  any  space  between
       the option, = and value.

       Each  setting  has  a  compiled in default which may be modified in the
       configuration file.

BOOLEAN OPTIONS

       Below is a list of boolean options. The value for a boolean option  may
       be set to YES or NO.

       allow_anon_ssl
              Only  applies  if ssl_enable is active. If set to YES, anonymous
              users will be allowed to use secured SSL connections.

              Default: NO

       anon_mkdir_write_enable
              If set to YES, anonymous users will be permitted to  create  new
              directories  under  certain  conditions.  For  this to work, the
              option write_enable must be activated,  and  the  anonymous  ftp
              user must have write permission on the parent directory.

              Default: NO

       anon_other_write_enable
              If  set  to  YES,  anonymous  users will be permitted to perform
              write operations other than upload and create directory, such as
              deletion  and  renaming.  This  is generally not recommended but
              included for completeness.

              Default: NO

       anon_upload_enable
              If set to YES, anonymous users will be permitted to upload files
              under   certain   conditions.  For  this  to  work,  the  option
              write_enable must be activated, and the anonymous ftp user  must
              have  write permission on desired upload locations. This setting
              is also required  for  virtual  users  to  upload;  by  default,
              virtual   users  are  treated  with  anonymous  (i.e.  maximally
              restricted) privilege.

              Default: NO

       anon_world_readable_only
              When enabled, anonymous users will only be allowed  to  download
              files which are world readable. This is recognising that the ftp
              user may own files, especially in the presence of uploads.

              Default: YES

       anonymous_enable
              Controls whether anonymous  logins  are  permitted  or  not.  If
              enabled,  both the usernames ftp and anonymous are recognised as
              anonymous logins.

              Default: YES

       ascii_download_enable
              When enabled, ASCII mode data  transfers  will  be  honoured  on
              downloads.

              Default: NO

       ascii_upload_enable
              When  enabled,  ASCII  mode  data  transfers will be honoured on
              uploads.

              Default: NO

       async_abor_enable
              When enabled, a special FTP command known as "async  ABOR"  will
              be enabled.  Only ill advised FTP clients will use this feature.
              Additionally, this feature  is  awkward  to  handle,  so  it  is
              disabled  by  default. Unfortunately, some FTP clients will hang
              when cancelling a transfer unless this feature is available,  so
              you may wish to enable it.

              Default: NO

       background
              When  enabled,  and  vsftpd  is started in "listen" mode, vsftpd
              will  background  the  listener  process.  i.e.   control   will
              immediately be returned to the shell which launched vsftpd.

              Default: NO

       check_shell
              Note!  This  option  only  has  an  effect for non-PAM builds of
              vsftpd. If disabled, vsftpd will not  check  /etc/shells  for  a
              valid user shell for local logins.

              Default: YES

       chmod_enable
              When  enables,  allows use of the SITE CHMOD command. NOTE! This
              only applies to local users. Anonymous users never  get  to  use
              SITE CHMOD.

              Default: YES

       chown_uploads
              If  enabled,  all  anonymously  uploaded  files  will  have  the
              ownership  changed  to  the  user  specified  in   the   setting
              chown_username.   This  is  useful  from  an administrative, and
              perhaps security, standpoint.

              Default: NO

       chroot_list_enable
              If activated, you may provide a list  of  local  users  who  are
              placed  in  a  chroot() jail in their home directory upon login.
              The meaning is slightly different if chroot_local_user is set to
              YES.  In  this  case, the list becomes a list of users which are
              NOT to be placed in a  chroot()  jail.   By  default,  the  file
              containing  this  list  is  /etc/vsftpd.chroot_list, but you may
              override this with the chroot_list_file setting.

              Default: NO

       chroot_local_user
              If set to YES, local users will be  (by  default)  placed  in  a
              chroot()  jail  in  their  home directory after login.  Warning:
              This option has security implications, especially if  the  users
              have upload permission, or shell access. Only enable if you know
              what you are doing.  Note that these security  implications  are
              not  vsftpd  specific. They apply to all FTP daemons which offer
              to put local users in chroot() jails.

              Default: NO

       connect_from_port_20
              This controls whether PORT style data connections  use  port  20
              (ftp-data)  on  the  server  machine. For security reasons, some
              clients may insist that this is the case. Conversely,  disabling
              this  option enables vsftpd to run with slightly less privilege.

              Default: NO (but the sample config file enables it)

       debug_ssl
              If true, OpenSSL connection diagnostics are dumped to the vsftpd
              log file.  (Added in v2.0.6).

              Default: NO

       delete_failed_uploads
              If  true,  any  failed  upload  files  are  deleted.   (Added in
              v2.0.7).

              Default: NO

       deny_email_enable
              If activated, you may provide a list of  anonymous  password  e-
              mail  responses  which cause login to be denied. By default, the
              file containing this list is /etc/vsftpd.banned_emails, but  you
              may override this with the banned_email_file setting.

              Default: NO

       dirlist_enable
              If  set  to NO, all directory list commands will give permission
              denied.

              Default: YES

       dirmessage_enable
              If enabled, users of the FTP server can be shown  messages  when
              they  first  enter  a  new directory. By default, a directory is
              scanned for the file .message, but that may be  overridden  with
              the configuration setting message_file.

              Default: NO (but the sample config file enables it)

       download_enable
              If set to NO, all download requests will give permission denied.

              Default: YES

       dual_log_enable
              If enabled, two log files are generated in  parallel,  going  by
              default to /var/log/xferlog and /var/log/vsftpd.log.  The former
              is a wu-ftpd style transfer log, parseable  by  standard  tools.
              The latter is vsftpd’s own style log.

              Default: NO

       force_dot_files
              If  activated,  files  and  directories  starting with . will be
              shown in directory listings even if the "a" flag was not used by
              the client. This override excludes the "." and ".." entries.

              Default: NO

       force_anon_data_ssl
              Only  applies  if  ssl_enable  is  activated.  If activated, all
              anonymous logins are forced to use a secure  SSL  connection  in
              order to send and receive data on data connections.

              Default: NO

       force_anon_logins_ssl
              Only  applies  if  ssl_enable  is  activated.  If activated, all
              anonymous logins are forced to use a secure  SSL  connection  in
              order to send the password.

              Default: NO

       force_local_data_ssl
              Only  applies if ssl_enable is activated. If activated, all non-
              anonymous logins are forced to use a secure  SSL  connection  in
              order to send and receive data on data connections.

              Default: YES

       force_local_logins_ssl
              Only  applies if ssl_enable is activated. If activated, all non-
              anonymous logins are forced to use a secure  SSL  connection  in
              order to send the password.

              Default: YES

       guest_enable
              If  enabled,  all  non-anonymous  logins  are classed as "guest"
              logins. A guest login is remapped to the user specified  in  the
              guest_username setting.

              Default: NO

       hide_ids
              If enabled, all user and group information in directory listings
              will be displayed as "ftp".

              Default: NO

       listen If enabled, vsftpd will run in standalone mode. This means  that
              vsftpd  must not be run from an inetd of some kind. Instead, the
              vsftpd executable is run once directly. vsftpd itself will  then
              take care of listening for and handling incoming connections.

              Default: NO

       listen_ipv6
              Like  the listen parameter, except vsftpd will listen on an IPv6
              socket instead of an IPv4 one. This  parameter  and  the  listen
              parameter are mutually exclusive.

              Default: NO

       local_enable
              Controls  whether local logins are permitted or not. If enabled,
              normal user accounts in /etc/passwd (or wherever your PAM config
              references)  may  be used to log in. This must be enable for any
              non-anonymous login to work, including virtual users.

              Default: NO

       lock_upload_files
              When enabled, all uploads proceed  with  a  write  lock  on  the
              upload  file.  All  downloads proceed with a shared read lock on
              the download file. WARNING!  Before enabling this, be aware that
              malicious readers could starve a writer wanting to e.g. append a
              file.

              Default: YES

       log_ftp_protocol
              When  enabled,  all  FTP  requests  and  responses  are  logged,
              providing  the  option xferlog_std_format is not enabled. Useful
              for debugging.

              Default: NO

       ls_recurse_enable
              When enabled, this setting will allow the use of "ls  -R".  This
              is  a minor security risk, because a ls -R at the top level of a
              large site may consume a lot of resources.

              Default: NO

       mdtm_write
              When  enabled,  this  setting  will  allow  MDTM  to  set   file
              modification times (subject to the usual access checks).

              Default: YES

       no_anon_password
              When  enabled, this prevents vsftpd from asking for an anonymous
              password - the anonymous user will log straight in.

              Default: NO

       no_log_lock
              When enabled, this prevents vsftpd from taking a file lock  when
              writing  to  log  files.  This  option  should  generally not be
              enabled. It exists to workaround operating system bugs  such  as
              the  Solaris  /  Veritas  filesystem  combination which has been
              observed to sometimes exhibit hangs trying to lock log files.

              Default: NO

       one_process_model
              If you have a  Linux  2.4  kernel,  it  is  possible  to  use  a
              different  security  model  which  only  uses  one  process  per
              connection. It is a less pure  security  model,  but  gains  you
              performance.  You  really  don’t  want to enable this unless you
              know what you are doing, and your site supports huge numbers  of
              simultaneously connected users.

              Default: NO

       passwd_chroot_enable
              If  enabled, along with chroot_local_user , then a chroot() jail
              location may be specified on a per-user basis. Each user’s  jail
              is  derived from their home directory string in /etc/passwd. The
              occurrence of /./ in the home directory string denotes that  the
              jail is at that particular location in the path.

              Default: NO

       pasv_addr_resolve
              Set  to  YES  if  you  want  to use a hostname (as opposed to IP
              address) in the pasv_address option.

              Default: NO

       pasv_enable
              Set to NO if you want to disallow the PASV method of obtaining a
              data connection.

              Default: YES

       pasv_promiscuous
              Set  to  YES if you want to disable the PASV security check that
              ensures the data connection originates from the same IP  address
              as the control connection.  Only enable if you know what you are
              doing! The only legitimate use for  this  is  in  some  form  of
              secure  tunnelling scheme, or perhaps to facilitate FXP support.

              Default: NO

       port_enable
              Set to NO if you want to disallow the PORT method of obtaining a
              data connection.

              Default: YES

       port_promiscuous
              Set  to  YES if you want to disable the PORT security check that
              ensures that outgoing data connections can only connect  to  the
              client. Only enable if you know what you are doing!

              Default: NO

       require_cert
              If  set  to  yes,  all  SSL  client  connections are required to
              present a client certificate. The degree of  validation  applied
              to  this  certificate  is  controlled by validate_cert (Added in
              v2.0.6).

              Default: NO

       run_as_launching_user
              Set to YES if you want vsftpd to run as the user which  launched
              vsftpd.  This  is  useful  where  root  access is not available.
              MASSIVE WARNING! Do NOT enable this option  unless  you  totally
              know  what you are doing, as naive use of this option can create
              massive security  problems.  Specifically,  vsftpd  does  not  /
              cannot  use  chroot technology to restrict file access when this
              option is set (even if launched  by  root).  A  poor  substitute
              could  be  to use a deny_file setting such as {/*,*..*}, but the
              reliability of this cannot compare to chroot, and should not  be
              relied  on.   If  using  this option, many restrictions on other
              options apply. For example, options requiring privilege such  as
              non-anonymous logins, upload ownership changing, connecting from
              port 20 and listen ports less than  1024  are  not  expected  to
              work. Other options may be impacted.

              Default: NO

       secure_email_list_enable
              Set to YES if you want only a specified list of e-mail passwords
              for anonymous logins to be accepted. This is useful  as  a  low-
              hassle way of restricting access to low-security content without
              needing  virtual  users.  When  enabled,  anonymous  logins  are
              prevented  unless  the  password  provided is listed in the file
              specified by the email_password_file setting. The file format is
              one password per line, no extra whitespace. The default filename
              is /etc/vsftpd.email_passwords.

              Default: NO

       session_support
              This controls whether vsftpd attempts to maintain  sessions  for
              logins.  If  vsftpd  is  maintaining  sessions,  it will try and
              update utmp and wtmp. It will also open a pam_session  if  using
              PAM  to  authenticate,  and only close this upon logout. You may
              wish to disable this if you do not need session logging, and you
              wish  to give vsftpd more opportunity to run with less processes
              and / or less privilege. NOTE - utmp and wtmp  support  is  only
              provided with PAM enabled builds.

              Default: NO

       setproctitle_enable
              If  enabled, vsftpd will try and show session status information
              in the system process listing. In other words, the reported name
              of  the  process will change to reflect what a vsftpd session is
              doing (idle, downloading etc). You probably want to  leave  this
              off for security purposes.

              Default: NO

       ssl_enable
              If enabled, and vsftpd was compiled against OpenSSL, vsftpd will
              support secure connections via SSL. This applies to the  control
              connection  (including  login) and also data connections. You’ll
              need a client with SSL support too. NOTE!!  Beware enabling this
              option.  Only  enable  it  if  you  need  it. vsftpd can make no
              guarantees about the  security  of  the  OpenSSL  libraries.  By
              enabling  this  option,  you  are  declaring  that you trust the
              security of your installed OpenSSL library.

              Default: NO

       ssl_request_cert
              If enabled, vsftpd will request (but  not  necessarily  require;

              should  not  cause any trouble at all, but IBM zOS seems to have
              issues.  (New in v2.0.7).

              Default: YES

       ssl_sslv2
              Only applies if ssl_enable is activated. If enabled, this option
              will permit SSL v2 protocol connections.  TLS v1 connections are
              preferred.

              Default: NO

       ssl_sslv3
              Only applies if ssl_enable is activated. If enabled, this option
              will permit SSL v3 protocol connections.  TLS v1 connections are
              preferred.

              Default: NO

       ssl_tlsv1
              Only applies if ssl_enable is activated. If enabled, this option
              will permit TLS v1 protocol connections.  TLS v1 connections are
              preferred.

              Default: YES

       strict_ssl_read_eof
              If enabled, SSL data uploads are required to terminate via  SSL,
              not  an  EOF  on  the socket. This option is required to be sure
              that an attacker did not terminate an upload prematurely with  a
              faked  TCP  FIN.  Unfortunately,  it  is  not enabled by default
              because so few clients get it right. (New in v2.0.7).

              Default: NO

       strict_ssl_write_shutdown
              If enabled, SSL data downloads are  required  to  terminate  via
              SSL,  not  an EOF on the socket. This is off by default as I was
              unable to find a single FTP client that does this. It is  minor.
              All  it  affects  is  our  ability  to  tell  whether the client
              confirmed full receipt of the file. Even  without  this  option,
              the  client is able to check the integrity of the download. (New
              in v2.0.7).

              Default: NO

       syslog_enable
              If enabled, then  any  log  output  which  would  have  gone  to
              /var/log/vsftpd.log  goes  to the system log instead. Logging is
              done under the FTPD facility.

              Default: NO

       tcp_wrappers
              If enabled, and vsftpd was compiled with  tcp_wrappers  support,
              incoming  connections  will  be  fed through tcp_wrappers access
              control. Furthermore, there is  a  mechanism  for  per-IP  based
              configuration.   If   tcp_wrappers   sets  the  VSFTPD_LOAD_CONF
              environment variable, then the vsftpd session will try and  load
              the vsftpd configuration file specified in this variable.

              Default: NO

       text_userdb_names
              By  default,  numeric IDs are shown in the user and group fields
              of directory listings. You can get  textual  names  by  enabling
              this parameter. It is off by default for performance reasons.

              Default: NO

       tilde_user_enable
              If  enabled,  vsftpd  will  try  and  resolve  pathnames such as
              ~chris/pics, i.e. a tilde followed  by  a  username.  Note  that
              vsftpd  will  always resolve the pathnames ~ and ~/something (in
              this case the ~ resolves to the initial login  directory).  Note
              that  ~user  paths will only resolve if the file /etc/passwd may
              be found within the _current_ chroot() jail.

              Default: NO

       use_localtime
              If enabled, vsftpd will display directory listings with the time
              in  your  local  time  zone.  The default is to display GMT. The
              times returned by the MDTM FTP command are also affected by this
              option.

              Default: NO

       use_sendfile
              An  internal  setting  used  for testing the relative benefit of
              using the sendfile() system call on your platform.

              Default: YES

       userlist_deny
              This option is examined if userlist_enable is activated. If  you
              set  this  setting to NO, then users will be denied login unless
              they  are  explicitly  listed   in   the   file   specified   by
              userlist_file.   When  login  is  denied,  the  denial is issued
              before the user is asked for a password.

              Default: YES

       userlist_enable
              If enabled, vsftpd will load  a  list  of  usernames,  from  the
              filename  given  by  userlist_file.   If  a user tries to log in
              using a name in this file, they will be denied before  they  are
              asked for a password. This may be useful in preventing cleartext
              passwords being transmitted. See also userlist_deny.

              Default: NO

       validate_cert
              If set  to  yes,  all  SSL  client  certificates  received  must
              validate OK.  Self-signed certs do not constitute OK validation.
              (New in v2.0.6).

              Default: NO

       virtual_use_local_privs
              If enabled, virtual users will use the same privileges as  local
              users. By default, virtual users will use the same privileges as
              anonymous users, which tends to be more restrictive  (especially
              in terms of write access).

              Default: NO

       write_enable
              This   controls  whether  any  FTP  commands  which  change  the
              filesystem are allowed or not. These commands are:  STOR,  DELE,
              RNFR, RNTO, MKD, RMD, APPE and SITE.

              Default: NO

       xferlog_enable
              If enabled, a log file will be maintained detailling uploads and
              downloads.   By  default,  this   file   will   be   placed   at
              /var/log/vsftpd.log,  but  this location may be overridden using
              the configuration setting vsftpd_log_file.

              Default: NO (but the sample config file enables it)

       xferlog_std_format
              If enabled, the transfer log file will be  written  in  standard
              xferlog  format,  as used by wu-ftpd. This is useful because you
              can reuse existing transfer statistics generators.  The  default
              format  is more readable, however. The default location for this
              style of log file is /var/log/xferlog, but  you  may  change  it
              with the setting xferlog_file.

              Default: NO

NUMERIC OPTIONS

       Below  is  a list of numeric options. A numeric option must be set to a
       non negative integer. Octal numbers are supported, for  convenience  of
       the umask options. To specify an octal number, use 0 as the first digit
       of the number.

       accept_timeout
              The timeout, in  seconds,  for  a  remote  client  to  establish
              connection with a PASV style data connection.

              Default: 60

       anon_max_rate
              The  maximum  data transfer rate permitted, in bytes per second,
              for anonymous clients.

              Default: 0 (unlimited)

       anon_umask
              The value that the  umask  for  file  creation  is  set  to  for
              anonymous  users.  NOTE!  If  you  want to specify octal values,
              remember the "0" prefix otherwise the value will be treated as a
              base 10 integer!

              Default: 077

       chown_upload_mode
              The  file  mode to force for chown()ed anonymous uploads. (Added
              in v2.0.6).

              Default: 0600

       connect_timeout
              The timeout, in seconds, for a remote client to respond  to  our
              PORT style data connection.

              Default: 60

       data_connection_timeout
              The  timeout,  in  seconds, which is roughly the maximum time we
              permit data transfers to stall for  with  no  progress.  If  the
              timeout triggers, the remote client is kicked off.

              Default: 300

       delay_failed_login
              The  number  of  seconds  to  pause  prior to reporting a failed
              login.

              Default: 1

       delay_successful_login
              The number of seconds to pause prior to  allowing  a  successful
              login.

              Default: 0

       file_open_mode
              The  permissions  with  which uploaded files are created. Umasks
              are applied on top of this value. You may wish to change to 0777
              if you want uploaded files to be executable.

              Default: 0666

       ftp_data_port
              The port from which PORT style connections originate (as long as
              the poorly named connect_from_port_20 is enabled).

              Default: 20

       idle_session_timeout
              The timeout, in seconds, which is  the  maximum  time  a  remote
              client  may spend between FTP commands. If the timeout triggers,
              the remote client is kicked off.

              Default: 300

       listen_port
              If vsftpd is in standalone mode, this is the port it will listen
              on for incoming FTP connections.

              Default: 21

       local_max_rate
              The  maximum  data transfer rate permitted, in bytes per second,
              for local authenticated users.

              Default: 0 (unlimited)

       local_umask
              The value that the umask for file creation is set to  for  local
              users.  NOTE!  If you want to specify octal values, remember the
              "0" prefix otherwise the value will be  treated  as  a  base  10
              integer!

              Default: 077

       max_clients
              If  vsftpd  is in standalone mode, this is the maximum number of
              clients  which  may  be  connected.   Any   additional   clients
              connecting will get an error message.

              Default: 0 (unlimited)

       max_login_fails
              After this many login failures, the session is killed.

              Default: 3

       max_per_ip
              If  vsftpd  is in standalone mode, this is the maximum number of
              clients which may be connected from  the  same  source  internet
              address. A client will get an error message if they go over this
              limit.

              Default: 0 (unlimited)

       pasv_max_port
              The maximum port to allocate for PASV  style  data  connections.
              Can   be   used  to  specify  a  narrow  port  range  to  assist
              firewalling.

              Default: 0 (use any port)

       pasv_min_port
              The minimum port to allocate for PASV  style  data  connections.
              Can   be   used  to  specify  a  narrow  port  range  to  assist
              firewalling.

              Default: 0 (use any port)

       trans_chunk_size
              You probably don’t want to change this, but try  setting  it  to
              something like 8192 for a much smoother bandwidth limiter.

              Default: 0 (let vsftpd pick a sensible setting)

STRING OPTIONS

       Below is a list of string options.

       anon_root
              This  option  represents  a  directory  which vsftpd will try to
              change into  after  an  anonymous  login.  Failure  is  silently
              ignored.

              Default: (none)

       banned_email_file
              This option is the name of a file containing a list of anonymous
              e-mail passwords which are not permitted. This file is consulted
              if the option deny_email_enable is enabled.

              Default: /etc/vsftpd.banned_emails

       banner_file
              This  option  is  the  name of a file containing text to display
              when someone connects to the server. If set,  it  overrides  the
              banner string provided by the ftpd_banner option.

              Default: (none)

       ca_certs_file
              This  option is the name of a file to load Certificate Authority
              certs  from,  for  the  purpose  of  validating  client   certs.
              Regrettably, the default SSL CA cert paths are not used, because
              of vsftpd’s use of restricted filesystem spaces (chroot). (Added
              in v2.0.6).

              Default: (none)

       chown_username
              This  is  the  name  of  the  user  who  is  given  ownership of
              anonymously uploaded files. This  option  is  only  relevant  if
              another option, chown_uploads, is set.

              Default: root

       chroot_list_file
              The  option  is  the  name  of a file containing a list of local
              users which will be placed in a  chroot()  jail  in  their  home
              directory.   This   option   is  only  relevant  if  the  option
              chroot_list_enable is enabled. If the  option  chroot_local_user
              is  enabled,  then  the list file becomes a list of users to NOT
              place in a chroot() jail.

              Default: /etc/vsftpd.chroot_list

       cmds_allowed
              This options specifies a comma separated  list  of  allowed  FTP
              commands  (post  login.  USER,  PASS and QUIT are always allowed
              pre-login). Other commands are  rejected.  This  is  a  powerful
              method   of   really   locking  down  an  FTP  server.  Example:
              cmds_allowed=PASV,RETR,QUIT

              Default: (none)

       deny_file
              This option can be used to set  a  pattern  for  filenames  (and
              directory names etc.) which should not be accessible in any way.
              The affected items  are  not  hidden,  but  any  attempt  to  do
              anything  to  them  (download,  change  into  directory,  affect
              something within directory etc.) will be denied. This option  is
              very simple, and should not be used for serious access control -
              the filesystem’s  permissions  should  be  used  in  preference.
              However,  this  option  may  be  useful  in certain virtual user
              setups. In particular aware that if a filename is accessible  by
              a  variety  of  names  (perhaps  due  to  symbolic links or hard
              links), then care must be taken to deny access to all the names.
              Access will be denied to items if their name contains the string
              given by hide_file, or if  they  match  the  regular  expression
              specified  by  hide_file.  Note that vsftpd’s regular expression
              matching code is a simple implementation which is  a  subset  of
              full regular expression functionality. Because of this, you will
              need to carefully and exhaustively test any application of  this
              option.  And  you  are recommended to use filesystem permissions
              for  any  important  security  policies  due  to  their  greater
              reliability.  Supported  regex  syntax is any number of *, ? and
              unnested {,} operators. Regex matching is only supported on  the
              last  component  of a path, e.g. a/b/? is supported but a/?/c is
              not.  Example: deny_file={*.mp3,*.mov,.private}

              Default: (none)

       dsa_cert_file
              This option specifies the location of the DSA certificate to use
              for SSL encrypted connections.

              Default: (none - an RSA certificate suffices)

       dsa_private_key_file
              This option specifies the location of the DSA private key to use
              for SSL encrypted connections. If this option is  not  set,  the
              private  key  is  expected  to  be  in  the  same  file  as  the
              certificate.

              Default: (none)

       email_password_file
              This option can be used to provide an alternate file  for  usage
              by the secure_email_list_enable setting.

              Default: /etc/vsftpd.email_passwords

       ftp_username
              This  is the name of the user we use for handling anonymous FTP.
              The home directory of this user is the root of the anonymous FTP
              area.

              Default: ftp

       ftpd_banner
              This  string  option  allows you to override the greeting banner
              displayed by vsftpd when a connection first comes in.

              Default: (none - default vsftpd banner is displayed)

       guest_username
              See the boolean setting guest_enable for a description  of  what
              constitutes  a  guest  login.  This setting is the real username
              which guest users are mapped to.

              Default: ftp

       hide_file
              This option can be used to set  a  pattern  for  filenames  (and
              directory  names  etc.)  which  should  be hidden from directory
              listings. Despite being hidden, the files / directories etc. are
              fully accessible to clients who know what names to actually use.
              Items will be hidden if their names contain the string given  by
              hide_file,  or if they match the regular expression specified by
              hide_file. Note that vsftpd’s regular expression  matching  code
              is  a  simple  implementation  which is a subset of full regular
              expression functionality.  See deny_file for details of  exactly
              what      regex      syntax      is     supported.      Example:
              hide_file={*.mp3,.hidden,hide*,h?}

              Default: (none)

       listen_address
              If vsftpd is in standalone mode, the default listen address  (of
              all local interfaces) may be overridden by this setting. Provide
              a numeric IP address.

              Default: (none)

       listen_address6
              Like listen_address, but specifies a default listen address  for
              the  IPv6 listener (which is used if listen_ipv6 is set). Format
              is standard IPv6 address format.

              Default: (none)

       local_root
              This option represents a directory  which  vsftpd  will  try  to
              change into after a local (i.e. non-anonymous) login. Failure is
              silently ignored.

              Default: (none)

       message_file
              This option is the name of the file  we  look  for  when  a  new
              directory  is  entered. The contents are displayed to the remote
              user.   This   option   is   only   relevant   if   the   option
              dirmessage_enable is enabled.

              Default: .message

       nopriv_user
              This  is  the  name  of  the user that is used by vsftpd when it
              wants to be totally unprivileged. Note that  this  should  be  a
              dedicated  user, rather than nobody. The user nobody tends to be
              used for rather a lot of important things on most machines.

              Default: nobody

       pam_service_name
              This string is the name of the PAM service vsftpd will use.

              Default: vsftpd

       pasv_address
              Use this option to override the  IP  address  that  vsftpd  will
              advertise  in response to the PASV command. Provide a numeric IP
              address, unless pasv_addr_resolve is enabled, in which case  you
              can  provide  a  hostname  which will be DNS resolved for you at
              startup.

              Default:  (none  -  the  address  is  taken  from  the  incoming
              connected socket)

       rsa_cert_file
              This option specifies the location of the RSA certificate to use
              for SSL encrypted connections.

              Default: /usr/share/ssl/certs/vsftpd.pem

       rsa_private_key_file
              This option specifies the location of the RSA private key to use
              for  SSL  encrypted  connections. If this option is not set, the
              private  key  is  expected  to  be  in  the  same  file  as  the
              certificate.

              Default: (none)

       secure_chroot_dir
              This  option  should  be the name of a directory which is empty.
              Also, the directory should not be writable by the ftp user. This
              directory is used as a secure chroot() jail at times vsftpd does
              not require filesystem access.

              Default: /var/run/vsftpd

       ssl_ciphers
              This option can be used to select which SSL ciphers vsftpd  will
              allow  for  encrypted  SSL connections. See the ciphers man page
              for further details. Note that  restricting  ciphers  can  be  a
              useful  security  precaution  as  it  prevents  malicious remote
              parties forcing a cipher which they have found problems with.

              Default: DES-CBC3-SHA

       user_config_dir
              This powerful option allows the override of  any  config  option
              specified  in  the  manual  page,  on a per-user basis. Usage is
              simple, and is best illustrated with  an  example.  If  you  set
              user_config_dir  to  be /etc/vsftpd_user_conf and then log on as
              the user "chris", then vsftpd will apply  the  settings  in  the
              file   /etc/vsftpd_user_conf/chris   for  the  duration  of  the
              session. The format of this file is as detailed in  this  manual
              page!  PLEASE NOTE that not all settings are effective on a per-
              user basis. For example, many settings only prior to the  user’s
              session  being  started.  Examples  of  settings  which will not
              affect any behviour on a per-user basis include  listen_address,
              banner_file, max_per_ip, max_clients, xferlog_file, etc.

              Default: (none)

       user_sub_token
              This  option  is useful is conjunction with virtual users. It is
              used to automatically generate a home directory for each virtual
              user, based on a template. For example, if the home directory of
              the    real    user    specified    via    guest_username     is
              /home/virtual/$USER,  and  user_sub_token  is set to $USER, then
              when virtual  user  fred  logs  in,  he  will  end  up  (usually
              chroot()’ed)  in  the directory /home/virtual/fred.  This option
              also takes affect if local_root contains user_sub_token.

              Default: (none)

       userlist_file
              This  option  is  the  name  of  the  file   loaded   when   the
              userlist_enable option is active.

              Default: /etc/vsftpd.user_list

       vsftpd_log_file
              This option is the name of the file to which we write the vsftpd
              style  log  file.  This  log  is  only  written  if  the  option
              xferlog_enable  is  set,  and  xferlog_std_format  is  NOT  set.
              Alternatively,  it  is  written  if  you  have  set  the  option
              dual_log_enable.   One  further  complication  - if you have set
              syslog_enable, then this file is not written and output is  sent
              to the system log instead.

              Default: /var/log/vsftpd.log

       xferlog_file
              This  option  is  the name of the file to which we write the wu-
              ftpd style transfer log. The transfer log is only written if the
              option  xferlog_enable  is  set,  along with xferlog_std_format.
              Alternatively,  it  is  written  if  you  have  set  the  option
              dual_log_enable.

              Default: /var/log/xferlog
