vsftpd.conf file

# Example config file /etc/vsftpd.conf
   #
   # The default compiled in settings are fairly paranoid. This sample file
   # loosens things up a bit, to make the ftp daemon more usable.
   # Please see vsftpd.conf for all compiled in defaults.
   #
   # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
   # Please read the vsftpd.conf manual page to get a full idea of vsftpd's
   # capabilities.
  #
  #
  # Run standalone?  vsftpd can run either from an inetd or as a standalone
  # daemon started from an initscript.
  listen=NO
  #
  # This directive enables listening on IPv6 sockets. By default, listening
  # on the IPv6 "any" address (::) will accept connections from both IPv6
  # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
  # sockets. If you want that (perhaps because you want to listen on specific
  # addresses) then you must run two copies of vsftpd with two configuration
  # files.
  listen_ipv6=YES
  #
  # Allow anonymous FTP? (Disabled by default).
  anonymous_enable=YES
 
  no_anon_password=YES
 
  ftp_username=ftp
  anon_root=/var/ftp
 
  #
  # Uncomment this to allow local users to log in.
  local_enable=YES
  #
  # Uncomment this to enable any form of FTP write command.
  write_enable=YES
  #
  # Default umask for local users is  You may wish to change this to ,
  # if your users expect that ( is used by most other ftpd's)
  #local_umask=
  #
  # Uncomment this to allow the anonymous FTP user to upload files. This only
  # has an effect if the above global write enable is activated. Also, you will
  # obviously need to create a directory writable by the FTP user.
  anon_upload_enable=YES
 
  anon_world_readable_only=YES
  #
  # Uncomment this if you want the anonymous FTP user to be able to create
  # new directories.
  anon_mkdir_write_enable=YES
 
  anon_other_write_enable=YES
  #
  # Activate directory messages - messages given to remote users when they
  # go into a certain directory.
  dirmessage_enable=YES
  #
  # 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.
  use_localtime=YES
  #
  # Activate logging of uploads/downloads.
  xferlog_enable=YES
  #
  # Make sure PORT transfer connections originate from port  (ftp-data).
  connect_from_port_20=YES
  #
  # If you want, you can arrange for uploaded anonymous files to be owned by
  # a different user. Note! Using "root" for uploaded files is not
  # recommended!
  #chown_uploads=YES
  chown_username=ftp
 
  anon_umask=
  #
  # You may override where the log file goes if you like. The default is shown
  # below.
  #xferlog_file=/var/log/vsftpd.log
  #
  # If you want, you can have your log file in standard ftpd xferlog format.
  # Note that the default log file location is /var/log/xferlog in this case.
  #xferlog_std_format=YES
  #
  # You may change the default value for timing out an idle session.
  #idle_session_timeout=
  #
  # You may change the default value for timing out a data connection.
  #data_connection_timeout=
  #
  # It is recommended that you define on your system a unique user which the
  # ftp server can use as a totally isolated and unprivileged user.
  #nopriv_user=ftpsecure
  #
  # Enable this and the server will recognise asynchronous ABOR requests. Not
  # recommended for security (the code is non-trivial). Not enabling it,
 # however, may confuse older FTP clients.
 #async_abor_enable=YES
 #
 # By default the server will pretend to allow ASCII mode but in fact ignore
 # the request. Turn on the below options to have the server actually do ASCII
 # mangling on files when in ASCII mode.
 # Beware that on some FTP servers, ASCII support allows a denial of service
 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
 # predicted this attack and has always been safe, reporting the size of the
 # raw file.
 # ASCII mangling is a horrible feature of the protocol.
 ascii_upload_enable=YES
 ascii_download_enable=YES
 #
 # You may fully customise the login banner string:
 ftpd_banner=Welcome to blah FTP service.
 #
 # You may specify a file of disallowed anonymous e-mail addresses. Apparently
 # useful for combatting certain DoS attacks.
 #deny_email_enable=YES
 # (default follows)
 #banned_email_file=/etc/vsftpd.banned_emails
 #
 # You may restrict local users to their home directories.  See the FAQ for
 # the possible risks in this before using chroot_local_user or
 # chroot_list_enable below.
 #chroot_local_user=YES
 #
 # You may specify an explicit list of local users to chroot() to their home
 # directory. If chroot_local_user is YES, then this list becomes a list of
 # users to NOT chroot().
 # (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
 # the user does not have write access to the top level directory within the
 # chroot)
 #local_root=/var/ftp
 allow_writeable_chroot=YES
 chroot_local_user=YES
 chroot_list_enable=NO
 # (default follows)
 chroot_list_file=/etc/vsftpd.chroot_list
 #
 # You may activate the "-R" option to the builtin ls. This is disabled by
 # default to avoid remote users being able to cause excessive I/O on large
 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
 # the presence of the "-R" option, so there is a strong case for enabling it.
 #ls_recurse_enable=YES
 #
 # Customization
 #
 # Some of vsftpd's settings don't fit the filesystem layout by
 # default.
 #
 # 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.
 secure_chroot_dir=/var/run/vsftpd/empty
 #
 # This string is the name of the PAM service vsftpd will use.
 pam_service_name=vsftpd
 #
 # This option specifies the location of the RSA certificate to use for SSL
 # encrypted connections.
 rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
 rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
 ssl_enable=NO

 #
 # Uncomment this to indicate that vsftpd use a utf8 filesystem.
 #utf8_filesystem=YES
