vsftpd.conf file

  1 # Example config file /etc/vsftpd.conf
  2 #
  3 # The default compiled in settings are fairly paranoid. This sample file
  4 # loosens things up a bit, to make the ftp daemon more usable.
  5 # Please see vsftpd.conf.5 for all compiled in defaults.
  6 #
  7 # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
  8 # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
  9 # capabilities.
 10 #
 11 #
 12 # Run standalone?  vsftpd can run either from an inetd or as a standalone
 13 # daemon started from an initscript.
 14 listen=NO
 15 #
 16 # This directive enables listening on IPv6 sockets. By default, listening
 17 # on the IPv6 "any" address (::) will accept connections from both IPv6
 18 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6
 19 # sockets. If you want that (perhaps because you want to listen on specific
 20 # addresses) then you must run two copies of vsftpd with two configuration
 21 # files.
 22 listen_ipv6=YES
 23 #
 24 # Allow anonymous FTP? (Disabled by default).
 25 anonymous_enable=YES

 35 #
 36 # Uncomment this to enable any form of FTP write command.
 37 write_enable=YES
 38 #
 39 # Default umask for local users is 077. You may wish to change this to 022,
 40 # if your users expect that (022 is used by most other ftpd's)
 41 #local_umask=002
 42 #
 43 # Uncomment this to allow the anonymous FTP user to upload files. This only
 44 # has an effect if the above global write enable is activated. Also, you will
 45 # obviously need to create a directory writable by the FTP user.
 46 anon_upload_enable=YES
 47
 48 anon_world_readable_only=YES
 49 #
 50 # Uncomment this if you want the anonymous FTP user to be able to create

 58 dirmessage_enable=YES
 59 #
 60 # If enabled, vsftpd will display directory listings with the time
 61 # in  your  local  time  zone.  The default is to display GMT. The
 62 # times returned by the MDTM FTP command are also affected by this
 63 # option.

 83 #
 84 # If you want, you can have your log file in standard ftpd xferlog format.

 88 # You may change the default value for timing out an idle session.

 95 # ftp server can use as a totally isolated and unprivileged user.
 96 #nopriv_user=ftpsecure
 97 #
 98 # Enable this and the server will recognise asynchronous ABOR requests. Not
 99 # recommended for security (the code is non-trivial). Not enabling it,
100 # however, may confuse older FTP clients.
101 #async_abor_enable=YES
102 #
103 # By default the server will pretend to allow ASCII mode but in fact ignore
104 # the request. Turn on the below options to have the server actually do ASCII
105 # mangling on files when in ASCII mode.
106 # Beware that on some FTP servers, ASCII support allows a denial of service
107 # attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
108 # predicted this attack and has always been safe, reporting the size of the
109 # raw file.
110 # ASCII mangling is a horrible feature of the protocol.

113 #
114 # You may fully customise the login banner string:

122 #
123 # You may restrict local users to their home directories.  See the FAQ for

126 #chroot_local_user=YES
127 #
128 # You may specify an explicit list of local users to chroot() to their home
129 # directory. If chroot_local_user is YES, then this list becomes a list of
130 # users to NOT chroot().
131 # (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
132 # the user does not have write access to the top level directory within the

140 #
141 # You may activate the "-R" option to the builtin ls. This is disabled by
142 # default to avoid remote users being able to cause excessive I/O on large
143 # sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
144 # the presence of the "-R" option, so there is a strong case for enabling it.

147 # Customization
148 #
149 # Some of vsftpd's settings don't fit the filesystem layout by
150 # default.
151 #
152 # This option should be the name of a directory which is empty.  Also, the
153 # directory should not be writable by the ftp user. This directory is used
154 # as a secure chroot() jail at times vsftpd does not require filesystem
155 # access.
