vsftpd2.0.3上传多层目录时出现550 failed to change directory如何解决?

twceng

我用vsftpd建的FTP，在客户端上传多重目录时提示550 failed to change directory 但是狂按确定后，查看上传的文件是完整的！这问题搜遍各大BBS都没有解决，那位高人路人帮个忙解决一下。以下是我的vsftpd.conf文件：
# 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.
#
# 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=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
#
# 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
listen=YES
charset_filter_enable=YES
charset_client=GB2312
charset_server=UTF8
anon_umask=000
anon_world_readable_only=NO
anon_other_write_enable=YES

其中vsftpd.chroot_list为空。上传目录PUB权限777
SLED10
uname -r

Lssac

有进vsftpd 很怪的~~~有时明明设置 没有 错误可就是不行。。。
你试试重新安装。。。下次先备份vsftpd.conf
不行再重新来一次试试看。

我昨天自己建了一个多层目录：
/Desktop/untitled folder/
../
untitled folder/
Thunder.sh
xmms.sh

如上共三层如上，每层一样，在看上传详细日志时发现了如下问题

主要是上传文件是要修改UTIME和chmod权限两个文件属性时发生权限不够(write_enable=yes)，然后我看了ps -aux 看到连进来的是vsftpd子进程的属主是nobody，我是用的root启动的vsftpd，怎么别人进来是nobody的属主，那会不会因为这个进来时修改文件属性权限不够，我找到了问题但不知道怎么解决。。。。。

权老实

我也遇到过，后来忘记怎么解决了。
主要还是权限问题
你可以试一下，先在FTP建个目录，有读写（当然也有执行）权限。
再试试上传到这个目录？？？

晨想

nobody 的话，那么相应的目录 nobody 也要能写入啊。

我测试了，没问题的说。
