求助"vsftpd匿名访问问题"

shihaoknox

vsftpd用匿名可以进入...也可以下载...但不可以下传和删除改名...我看了看配置文件应该没什么问题...请大家帮我看看...谢谢...上传的时间有提示...


# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are very paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
#
# Allow anonymous FTP?
anonymous_enable=yes
anon_root=/root/tmp
#
# 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=022
file_open_mode=0666
#
# 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
anon_other_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 vsFTPd 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=no
# (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

guest_enable=yes
guest_username=shihao
user_config_dir=/etc/vsftpd/userconf
pam_service_name=vsftpd
userlist_enable=yes
userlist_deny=yes
#enable for standalone mode
listen=YES
#tcp_wrappers=YES

都没人回答吗?

ll /root/tmp
你看清楚是否有写权限。
把匿名ftp目录放在root下，超级高明。
vsftp是跟文件系统配合控制用户的。

shihaoknox

如果没有怎么改权限呀....偶是初学者....帮帮忙谢谢....这是我在x windows下的tmp文件夹属性...请帮我看看....哪里不对...

1． 匿名服务器的连接（独立的服务器）
在/etc/vsftpd/vsftpd.conf配置文件中添加如下几项：
Anonymous_enable=yes (允许匿名登陆)
Dirmessage_enable=yes （切换目录时，显示目录下.message的内容）
Local_umask=022 (FTP上本地的文件权限，默认是077)
Connect_form_port_20=yes （启用FTP数据端口的数据连接）*
Xferlog_enable=yes （激活上传和下传的日志）
Xferlog_std_format=yes (使用标准的日志格式)
Ftpd_banner=XXXXX （欢迎信息）
Pam_service_name=vsftpd （验证方式）*
Listen=yes （独立的VSFTPD服务器）*
功能：只能连接FTP服务器，不能上传和下传
注：其中所有和日志欢迎信息相关连的都是可选项,打了星号的无论什么帐户都要添加，是属于FTP的基本选项

2． 开启匿名FTP服务器上传权限
在配置文件中添加以下的信息即可：
Anon_upload_enable=yes (开放上传权限)
Anon_mkdir_write_enable=yes （可创建目录的同时可以在此目录中上传文件）
Write_enable=yes (开放本地用户写的权限)
Anon_other_write_enable=yes (匿名帐号可以有删除的权限)

3． 开启匿名服务器下传的权限
在配置文件中添加如下信息即可：
Anon_world_readable_only=no
注：要注意文件夹的属性，匿名帐户是其它（other）用户要开启它的读写执行的权限
（R）读-----下传 （W）写----上传 （X）执行----如果不开FTP的目录都进不去

shihaoknox

我照你的方法做了...我想可能是匿名对tmp文件夹读写执行权限不够吧...我把tmp文件夹中的other全都打上勾了...还是不行....现在连匿名登入都进不出了.....

shihaoknox

没人回答吗?

shihaoknox

我照上面的意思把tmp文件属性权限改了....我在flashftp中运行时...出现refusing to run with writable anonymous root 现在连anonymous也连不上了...这个是怎么回事呀...

shihaoknox

这么大一个论坛竞然没一个人回答....

你最好把目录放到别的地方，不然放在root里会给你带来很多不必要的麻烦的。
还有你先找一本linux文件系统和用户管理方面的书看一下。
等你知道了文件系统是如何面对用户的你就知道该怎么做了
