我的ftp为什么不能匿名登陆？

大虾们，搞不定啊！
proftpd.conf  文件
# 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

# Allow FTP resuming.
# Remember to set to off if you have an incoming ftp for upload.
AllowStoreRestart                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                                nobody
Group                                nogroup

# Normally, we want files to be overwriteable.
<Directory />
  AllowOverwrite                on
</Directory>

# Needed for NIS.
PersistentPasswd                off

# Default root can be used to put users in a chroot environment.
# As an example if you have a user foo and you want to put foo in /home/foo
# chroot environment you would do this:
#
# DefaultRoot /home/foo foo


#<drakwizard>
<Global>
  <Limit LOGIN>
    Order allow,deny
    Allow from all
    Deny from all
  </Limit>
</Global>
#</drakwizard>
Include                        /etc/proftpd-anonymous.conf

proftpd-anonymous.conf   文件
# A basic anonymous configuration, no upload directories.
<Anonymous ~ftp>
  User                                nobody
  Group                                nogroup
  # We want clients to be able to login with "anonymous" as well as "ftp"
  UserAlias                        anonymous nobody

  # Limit the maximum number of anonymous logins
  MaxClients                        10

  # Don't make it require a valid password or shell.
  RequireValidShell                off
  AnonRequirePassword                off

  # We want 'welcome.msg' displayed at login, and '.message' displayed
  # in each newly chdired directory.
  DisplayLogin                        welcome.msg
  DisplayFirstChdir                .message

  # Limit WRITE everywhere in the anonymous chroot
  <Limit WRITE>
    DenyAll
  </Limit>
  #设置匿名用户只有读取权限
  <Limit READ>
    AllowAll

UserAlias anonymous nobody

应该是
UserAlias anonymous ftp
而且要确定ftp用户的存在 /etc/passwd

(1)    系统里的nobody和ftp用户是怎么来的？nobody是系统自带的吗？ftp是安装了proftpd后软件自动增加的吗？

(2)    UserAlias anonymous ftp后，是否也应该把
# A basic anonymous configuration, no upload directories.
<Anonymous ~ftp>
User nobody
Group nogroup
和
# Set the user and group under which the server will run.
User nobody
Group nogroup
这两个地方的nobody用户改成ftp?是否这样一来nobody用户就没有用了，我可以把它删除了？

(3)      论坛上很多文章说要
# Set the user and group under which the server will run.
User nobody
Group nobody
我想问nobody用户应该是nogroup组里的,为什么要改成nobody？而且系统里没有预设nobody这样的组？

(4)      我的ftp用户的shell是/bin/false，那不是就不能登陆了？
