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

       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_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

       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 encrpyted 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
