我在vsftpd.conf中修改配置

`chroot_local_user=YES
allow_writeable_chroot=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list`

创建一个账号。不管是把该账号添加到chroot_list还是不添加,这个账号都可以通过FTP工具访问所有的目录并且可以拉去文件到本地。这个到底怎么回事。
我想要的是这个账号只能在其家目录中,不能访问到其它目录
按照网上的修改的。

vsftpd.conf

#vsftpd version 3.0.2

# Example config file etcvsftpdvsftpd.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.
#
# Allow anonymous FTP (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
# When SELinux is enforcing check for SE bool ftp_home_dir
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=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.
# When SELinux is enforcing check for SE bool allow_ftpd_anon_write, allow_ftpd_full_access
#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 uploadsdownloads.
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=varlogxferlog
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is varlogxferlog 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. The vsftpd.conf(5) man page explains
# the behaviour when these options are disabled.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command SIZE bigfile 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=etcvsftpdbanned_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().
# (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=etcvsftpdchroot_list

userlist_enable=YES
userlist_deny=NO
userlist_file=etcvsftpduser_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 IO 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=NO
#
# This directive enables listening on IPv6 sockets. By default, listening
# on the IPv6 any address () will accept connections from both IPv6
# and IPv4 clients. It is not necessary to listen on both IPv4 and IPv6
# sockets. If you want that (perhaps because you want to listen on specific
# addresses) then you must run two copies of vsftpd with two configuration
# files.
# Make sure, that one of the listen options is commented !!
listen_ipv6=YES

pam_service_name=vsftpd
userlist_enable=YES

我也想知道。

配置

chroot_list_enable=YES
chroot_list_file=/etc/vsftpd.chroot_list
chroot_local_user=YES

ftp 帐号不能添加到 vsftpd.chroot_list 文件,加了就不受限制。

改完配置记得重启服务。


你的配置有部分重复,路径似乎都少了斜杠。
这是整理之后的

allow_writeable_chroot=YES
anonymous_enable=NO
ascii_download_enable=YES
ascii_upload_enable=YES
chroot_list_enable=YES
chroot_list_file=/etc/vsftpd/chroot_list
chroot_local_user=YES
connect_from_port_20=YES
dirmessage_enable=YES
listen_ipv6=YES
listen=NO
local_enable=YES
local_umask=022
pam_service_name=vsftpd
tcp_wrappers=YES
userlist_deny=NO
userlist_enable=YES
userlist_file=/etc/vsftpd/user_list
write_enable=YES
xferlog_enable=YES
xferlog_std_format=YES

我测试环境

  1. 系统 centos7,vsftpd 3.0.2
  2. user_list 文件只有一行 guest
  3. chroot_list 文件是空的
  4. 创建测试用户 useradd -m guest

guest 登录 ftp 后,只能访问自己的目录,并不能访问系统其他目录。
