ubuntu14.04 安装VSFTPD，可以FTP下载但是FTP上传时报“550 Permission denied.”恳请各位大神求助
我把FTP主目录文件夹的权限都设置成777了，但还是不能上传（下载文件是可以的）
配置文件（/etc/vsftpd.conf)那里我是设置成用本地用户登录的；
write_enable=YES，这个东西也设置了。我已经搞了2天了，都没搞好，要崩溃了。。。。
配置脚本如下：
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
#
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=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=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.
xferlog_enable=YES
#
Make sure PORT transfer connections originate from port 20 (ftp-data).
#connect_from_port_20=YES
port_enable=NO
connetc_from_port_20=NO
#
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.
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
#wei add
seccomp_sandbox=NO
userlist_enable=YES
userlist_deny=YES
userlist_file=/etc/allowed_users
pasv_enable=YES
pasv_max_port=0
