Bom dia !


Estou com um problema no vsftpd, os usuários estão conseguindo se conectar sem colocar a senha, colocando somente o usuário ele já abre o ftp, alguem de vocês ja passaram por isso no aguardo.

OBS: Estou usando o Fedora 8.

Vou te passar como está a minha configuração. Estou usando "chroot list", nesse arquivo estão os usuários que podem se conectar, qualquer outro usuário é negado.

# Allow anonymous FTP? (Beware - allowed by default if you comment this out).

anonymous_enable=NO

#

# 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=000

#

# 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

#

# Activate logging of uploads/downloads.

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

#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

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 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_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 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.

#ls_recurse_enable=YES



pam_service_name=vsftpd

#userlist_enable=YES



#enable for standalone mode

listen=YES

tcp_wrappers=YES



# Esconder UID e GID real, mostrando somente ftp/ftp

hide_ids=YES
