Créer un serveur VSFTPD avec un accès anonyme
Je souhaite configurer un serveur FTP sous Ubuntu 14.04 J'ai un accès complet au serveur et aucun tutoriel trouvé en ligne ne me dit exactement comment y accéder.
J'utilise VSFTPD à cause de nombreuses suggestions.
Cependant, il ne répond toujours pas tout à fait à la question d'utiliser un FTP pour l'accès au serveur, car cela devrait permettre aux personnes anonymes de télécharger à partir de celui-ci.
Toute aide serait appréciée
(Il a acheté le site FTP de mon ami) http://uje.dev9.org/etmain/
Ce serait un exemple de quelque chose que je veux mettre en place. N'importe quoi, même proche de cela fonctionnerait, je veux juste pouvoir télécharger anonymement à partir de ça.
EDIT
Certains paramètres ont été modifiés à cause d'un autre thread askubuntu.
anonymous_enable=YES
local_enable=NO
write_enable=NO
anon_root=/srv/ftp
anon_max_rate=2048000
xferlog_enable=YES
listen=YES
Mon dernier problème est que, même lorsque j'essaie de me connecter anonymement, il me demande toujours un mot de passe. Comment puis-je résoudre ce problème?
Ma config est:
# 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.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.
#
#
# Run standalone? vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
listen=YES
anon_root=/src/ftp
anon_max_rate=2048000
#
# Run standalone with 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.
#listen_ipv6=YES
#
# Allow anonymous FTP? (Disabled by default)
anonymous_enable=YES
#
# Uncomment this to allow local users to log in.
local_enable=NO
#
# Uncomment this to enable any form of FTP write command.
write_enable=NO
#
# 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.
#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
#
# 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.
ferlog_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
#chown_username=whoever
#
# 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=600
#
# You may change the default value for timing out a data connection.
#data_connection_timeout=120
#
# 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)
#chroot_local_user=YES
#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.
#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
# This option specifies the location of the RSA key to use for SSL
# encrypted connections.
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
Ajoutez ceci à votre config:
no_anon_password=YES
De vsftpd.conf (5):
no_anon_password
When enabled, this prevents vsftpd from asking for an anonymous password - the anonymous user will
log straight in.
Default: NO
Je préfère vsftpd dans Ubuntu. Ils ont un guide avec la configuration d'accès anonyme. Ceci est pris de https://help.ubuntu.com/10.04/serverguide/ftp-server.html
Par défaut, vsftpd est configuré pour autoriser uniquement le téléchargement anonyme. Lors de l'installation, un utilisateur ftp est créé avec un répertoire personnel/home/ftp. C'est le répertoire FTP par défaut.
Si vous souhaitez modifier cet emplacement, par exemple en/srv/ftp, créez simplement un répertoire à un autre emplacement et modifiez le répertoire de base de l'utilisateur ftp:
Sudo mkdir /srv/ftp
Sudo usermod -d /srv/ftp ftp
Après avoir effectué le changement, redémarrez vsftpd:
Sudo /etc/init.d/vsftpd restart
Enfin, copiez tous les fichiers et répertoires que vous souhaitez rendre disponibles via FTP anonyme vers/srv/ftp.
