# Allow anonymous FTP?

#
# Uncomment this to allow local users to log in.
#local_enable=YES
#
# Uncomment this to enable any form of FTP write command.

# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
#local_umask=022
#
# 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.

#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.

#
# Activate directory messages - messages given to remote users when they

#
# Make sure PORT transfer connections originate from port 20 (ftp-data).

#
# If you want, you can arrange for uploaded anonymous files to be owned by

#
# You may override where the log file goes if you like. The default is shown

# 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 turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be
# on the client anyway..

#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 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().
#chroot_list_enable=YES
# (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.

关于vsftpd.conf中一些极为重要的说明：有些是在vsftpd.conf中是没有的，我们也可以加上
.TH VSFTPD.CONF 5
.SH NAME
vsftpd.conf, the config file for vsftpd
.SH DESCRIPTION
vsftpd.conf may be used to control various aspects of vsftpd's behaviour. By
default, vsftpd looks for this file at the location
.BR /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
.BR xinetd
to launch vsftpd with different configuration files on a per virtual host
basis.
.SH 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.
.SH BOOLEAN OPTIONS
Below is a list of boolean options. The value for a boolean option may be set
to
.BR YES
or
.BR NO .
.TP
.B 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
.BR write_enable
must be activated, and the anonymous ftp user must have write permission on
the parent directory.
Default: NO
.TP
.B 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
.TP
.B anon_upload_enable
If set to YES, anonymous users will be permitted to upload files under certain
conditions. For this to work, the option
.BR write_enable
must be activated, and the anonymous ftp user must have write permission on
desired upload locations.
Default: NO
.TP
.B 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
.TP
.B anonymous_enable
Controls whether anonymous logins are permitted or not. If enabled,
both the usernames
.BR ftp
and
.BR anonymous
are recognised as anonymous logins.
Default: YES
.TP
.B ascii_download_enable
When enabled, ASCII mode data transfers will be honoured on downloads.
Default: NO
.TP
.B ascii_upload_enable
When enabled, ASCII mode data transfers will be honoured on uploads.
Default: NO
.TP
.B 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. Addtionally, 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.
