vsftpd.conf - config file for vsftpd 
vsftpd.conf may be used to control various aspects of vsftpd's
    behaviour. By default, vsftpd looks for this file at the location
    /usr/local/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. 
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. 
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 enabled, 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
      /usr/local/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 /usr/local/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 
   
  - implicit_ssl
 
  - If enabled, an SSL handshake is the first thing expect on all connections
      (the FTPS protocol). To support explicit SSL and/or plain text too, a
      separate vsftpd listener process should be run.
    
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 
   
  - require_ssl_reuse
 
  - If set to yes, all SSL data connections are required to exhibit SSL
      session reuse (which proves that they know the same master secret as the
      control channel). Although this is a secure default, it may break many FTP
      clients, so you may want to disable it. For a discussion of the
      consequences, see
      http://scarybeastsecurity.blogspot.com/2009/02/vsftpd-210-released.html
      (Added in v2.1.0).
    
Default: YES 
   
  - 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 /usr/local/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; see
      require_cert)acertificateonincomingSSLconnections.Normallythis
      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 v1.2+ 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 v1.2+ connections are
      preferred.
    
Default: NO 
   
  - ssl_tlsv1
 
  - Only applies if ssl_enable is activated. If enabled, this option
      will permit TLS v1.0 protocol connections. TLS v1.2+ connections are
      preferred.
    
Default: NO 
   
  - ssl_tlsv1_1
 
  - Only applies if ssl_enable is activated. If enabled, this option
      will permit TLS v1.1 protocol connections. TLS v1.2+ connections are
      preferred.
    
Default: NO 
   
  - ssl_tlsv1_2
 
  - Only applies if ssl_enable is activated. If enabled, this option
      will permit TLS v1.2 protocol connections. TLS v1.2+ connections are
      preferred.
    
Default: YES 
   
  - ssl_tlsv1_3
 
  - Only applies if ssl_enable is activated. If enabled, this option
      will permit TLS v1.3 protocol connections. TLS v1.2+ 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 
    
   
 
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) 
    
   
 
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: /usr/local/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. The loaded certs are
      also advertised to the client, to cater for TLSv1.0 clients such as the
      z/OS FTP client. 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: /usr/local/etc/vsftpd.chroot_list 
   
  - cmds_allowed
 
  - This options specifies a comma separated list of allowed FTP commands
      (post login. USER, PASS and QUIT and others 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) 
   
  - cmds_denied
 
  - This options specifies a comma separated list of denied FTP commands (post
      login. USER, PASS, QUIT and others are always allowed pre-login). If a
      command appears on both this and cmds_allowed then the denial takes
      precedence. (Added in v2.1.0).
    
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: /usr/local/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: ftp 
   
  - 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) 
   
  - pid_file
 
  - This option has efect only if background is set. It writes pid of
      running daemon to file at the specified path.
    
Default: (none) (no pidfile is created) 
   
  - 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: /usr/share/empty 
   
  - 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 
   
  - ssl_sni_hostname
 
  - If set, SSL connections will be rejected unless the SNI hostname in the
      incoming handshakes matches this value.
    
Default: (none) 
   
  - 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
      /usr/local/etc/vsftpd_user_conf and then log on as the user
      "chris", then vsftpd will apply the settings in the file
      /usr/local/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: /usr/local/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
