我在虚拟机里安装了fedora 9,按照坛子里的文章架设了FTP，并把/var/ftp/pub目录的权限设置为了777，但是，匿名用户只能上传，删除和重命名，无法下载：（
仔细看了一下，是因为上传的文档（如TXT或PDF）没有执行权限，请问一下，我已经在vsftp.conf里将chown_upload = YES anon_umask = 777，为什么上传的文件还是不带执行权限呢？？
感谢

初学LINUX，给大家添麻烦了 感谢先，我现在实现下载的办法是：想下载哪个文件，先到linux下去chmod 777 XXX [XXX代表此文件名]
但是，不可能每个接入端都事先告诉我他要下载哪个文件吧：（
能否在上传时就让此文件有被下载的权限？

将我的vsftpd.conf 附上# Example config file /etc/vsftpd/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
anon_other_write_enable=YES

# Activate directory messages - messages given to remote users when they
# go into a certain directory.

#
# 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
anon_umask=777
file_open_mode=0777
#chown_username=
#
# 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.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" 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=/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
#
# 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=YES
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd whith two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
pam_service_name=vsftpd
userlist_enable=YES
tcp_wrappers=YES
另有var/ftp/pub目录下的权限抓图

感谢感谢，但不知anon_umask设置为多少才能让/var/ftp/pub下同时支持匿名的上传，删除，下载，重名等所有权限？（我改为077也不行）
比如我现在有上传了一个文件，想不在Linux下去再改权限就能直接下载
感谢感谢，

好久没用ftp了，支持一下！
txwsqk 于 2009-05-17 10:08:02发表:
楼主可以 man 5 vsftpd.conf 看下这个配置文件的详细说明
说明下 对文件有r的权限 那么就可以下载 而不是 x权限
楼主知道umask的意思 这是遮罩 你设置 anon_umask = 777 那么这个文件最后就会变成 000的权限你当然不能下载了

您的意思是，在LINUX下手动为每个文件进行权限设置？？
那每新增一个需要下载的文件时我都得到虚拟机里去设置？
如果一个新上传的文件需要马上被人下载，也需要我马上去设置这个文件权限？？
那样的话，一个LINUX FTP不是得时时刻刻有人来看着？？
希望我理解的是错误的，可否告之我在终端下如何完成您所说的设置，谢谢
