- # Example config file /etc/vsftpd/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.5 for all compiled in defaults.
- #
- # READ THIS: This example file is NOT an exhaustive list of vsftpd options.
- # Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
- # capabilities.
- #listen_ipv6=YES

- # Allow anonymous FTP? (Beware - allowed by default if you comment this out).
- anonymous_enable=YES
- #
- # 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 077. You may wish to change this to 022,
- # if your users expect that (022 is used by most other ftpd's)
- #local_umask=077
- #
- # 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
- #
- # Uncomment this if you want the anonymous FTP user to be able to create
- # new directories.
- anon_mkdir_write_enable=YES
- #
- # Activate directory messages - messages given to remote users when they
- # go into a certain directory.
- dirmessage_enable=YES
- use_localtime=YES
- # The target log file can be vsftpd_log_file or xferlog_file.
- # This depends on setting xferlog_std_format parameter
- xferlog_enable=YES
- #
- # Make sure PORT transfer connections originate from port 20 (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

- # 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:

- # You may specify a file of disallowed anonymous e-mail addresses. Apparently
- # useful for combatting certain DoS attacks.

- # (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_local_user=YES
- #chroot_list_enable=YES
- # (default follows)
- #chroot_list_file=/etc/vsftpd/chroot_list
- #secure_chroot_dir=/var/run/vsftpd/empty
- #
- # 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
- #
- # When "listen" directive is enabled, vsftpd runs in standalone mode and
- # listens on IPv4 sockets. This directive cannot be used in conjunction
- # with the listen_ipv6 directive.
- listen=YES
- #
- # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
- # sockets, you must run two copies of vsftpd with two configuration files.
- # Make sure, that one of the listen options is commented !!
