使proftpd的一个用户只有上传权限,而没有其他删除之类的权限

Question

这是我的proftpd的配置文件,帮忙看一下哪有出错了!!!!

# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.

ServerName                        "roFTPD Default Installation"
ServerType                        standalone
DefaultServer                        on

# Port 21 is the standard FTP port.
Port                                21

# Umask 022 is a good standard umask to prevent new dirs and files
# from being group and world writable.
Umask                                022

# To prevent DoS attacks, set the maximum number of child processes
# to 30.  If you need to allow more than 30 concurrent connections
# at once, simply increase this value.  Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd).
MaxInstances                        30

# Set the user and group under which the server will run.
User                                skate       
Group                                skate

# To cause every FTP user to be "jailed" (chrooted) into their home
# directory, uncomment this line.
DefaultRoot ~ skate,skate

# Normally, we want files to be overwriteable.
AllowOverwrite                on

# Bar use of SITE CHMOD by default
#<Limit SITE_CHMOD>;
#  DenyAll

# A basic anonymous configuration, no upload directories.  If you do not
# want anonymous users, simply delete this entire <Anonymous>; section.
<Anonymous ~ftp>;
