第二步：配置incoming子目录的权限

　　打开proftpd.conf，在和段之间添加如下设置：




　Order allow,deny
　Allow from 10.0.8.
　Deny from all




　　表示在incoming这个子目录下，从10.0.8这个网段登录的客户端有写入“WRITE”权限，其它人对该目录的写如权限都是被禁止的。如果要对所有的用户开放写入权限，只要把和之间的内容换成“Allowall“。

四、FTP服务器相关命令

1、ftpshut:关闭FTP服务，并在/etc下生成文件shutmsg。要重新开放FTP服务，把/etc/shutmsg删除。
2、ftpcout:FTP服务器在线人数信息显示。
3、ftpwho:FTP服务器在线人员名单。


附录：Proftpd.conf全文及解释

# 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 "MY REDHAT LINUX FTP" #设定FTP服务器的名称

ServerType standalone #设置FTP以Standalone模式运行，而不是以dameon模式

DefaultServer on #默认FTP服务器工作

# Port 21 is the standard FTP port.

Port 21 #FTP服务默认占用的端口

# Umask 022 is a good standard umask to prevent new dirs and files

# from being group and world writable.
Umask 022 #默认

RequireValidShell off #保证匿名用户正常登录，不要更改

ServerIdent off #不显示ftp服务器版本信息，以增强安全性

# 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 that the server normally runs at.

User nobody #设置FTP服务以nobody运行

Group nobody #注意：原来是“Group nobody”，一定要改为“Group nobody”

# Normally, we want files to be overwriteable.

　AllowOverwrite on


# A basic anonymous configuration, no upload directories.下面一段就是匿名服务的设置。


User ftp #匿名登录使用ftp用户

Group ftp #匿名登录使用ftp组

# We want clients to be able to login with "anonymous" as well as "ftp"

UserAlias anonymous guest #给ftp用户anonymous的别名，使得anonymous登录就是ftp用户登录。

# Limit the maximum number of anonymous logins

MaxClients 10 #最多10个匿名用户同时在线

# We want 'welcome.msg' displayed at login, and '.message' displayed

# in each newly chdired directory.

DisplayLogin welcome.msg #登录FTP显示的欢迎信息。放在FTP的根目录下。

DisplayFirstChdir .message

# Limit WRITE everywhere in the anonymous chroot

#说明看正文。


Order allow,deny
Allow from 10.0.8.
Deny from all
