阅读提示：四步介绍Ubuntu Linux 7.04系统安装并使用Proftp方法...

◆1- 使用下面的命令安装proftpd：

Code:

sudo apt-get install proftpd

◆2- 在etc/shells 加入如下代码 (sudo gedit /etc/shells to open the file)(译注:命令行模式下sudo vi /etc/shells) :

Code:

/bin/false

新建一个 /home/FTP-shared 目录 :

Code:

cd /home

sudo mkdir FTP-shared

创建一个只能用来读取ftp的用户userftp。这个用户不需要有效的shell(更安全) ,所以选择 /bin/false shell 给 userftp , /home/FTP-shared 作为主目录。

为了是这部分更清楚,我给取此操作的命令行：

Code:

sudo useradd userftp -p your_password -d /home/FTP-shared -s /bin/false

在FTP-shared 目录下新建一个download和一个upload 目录:

Code:

cd /home/FTP-shared/

sudo mkdir download

sudo mkdir upload

现在我们来给它们设置相应的权限:

Code:

cd /home

sudo chmod 755 FTP-shared

cd FTP-shared

sudo chmod 755 download

sudo chmod 777 upload

◆3- 好了,现在进入proftpd的配置文件:

Code:

sudo gedit /etc/proftpd/proftpd.conf //特别注意路径，网上以前给的是错的

当然你可以按你的需要编辑你自己的proftpd.conf:

Code:

# To really apply changes reload proftpd after modifications.
AllowOverwrite on
AuthAliasOnly on

# Choose here the user alias you want !!!!
UserAlias sauron userftp
ServerName "ChezFrodon"
ServerType standalone
DeferWelcome on
MultilineRFC2228 on
DefaultServer on
ShowSymlinks off

TimeoutNoTransfer 600
TimeoutStalled 100
TimeoutIdle 2200

DisplayFirstChdir .message
ListOptions "-l"
RequireValidShell off
TimeoutLogin 20
RootLogin off

# It's better for debug to create log files ;-)

ExtendedLog /var/log/ftp.log
TransferLog /var/log/xferlog
SystemLog /var/log/syslog.log

#DenyFilter \*.*/

# I don't choose to use /etc/ftpusers file (set inside the users you want to ban, not useful for me)
UseFtpUsers off

# Allow to restart a download
AllowStoreRestart on

# Port 21 is the standard FTP port, so don't use it for security reasons (choose here the port you want)
Port 1980

# 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 8

# Set the user and group that the server normally runs at.
User nobody
Group nogroup

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

PersistentPasswd off

MaxClients 8
MaxClientsPerHost 8
MaxClientsPerUser 8
MaxHostsPerUser 8

# Display a message after a successful login

AccessGrantMsg "welcome !!!"

# This message is displayed for each access good or not

ServerIdent on "you're at home"

# Set /home/FTP-shared directory as home directory

DefaultRoot /home/FTP-shared

# Lock all the users in home directory, ***** really important *****

DefaultRoot ~
MaxLoginAttempts 5

#VALID LOGINS

AllowUser userftp
DenyALL
Umask 022 022

AllowOverwrite off
DenyAll
Umask 022 022

AllowOverwrite off
DenyAll
Umask 022 022

AllowOverwrite on
DenyAll
AllowAll

好了,你已经完成了proftpd的配置,你的服务端口是1980,而读取的参数如下,用户:sauron,密码:你为userftp设置的那个。

◆4- 启动/停止/重启动你的服务:

Code:

sudo /etc/init.d/proftpd start
sudo /etc/init.d/proftpd stop
sudo /etc/init.d/proftpd restart

对你的proftpd进行一下语法检查:

Code:

sudo proftpd -td5

想知道谁现在连接到你的服务,用ftptop命令(使用字母"t"来转换显示频率),你也可以使用"ftpwho"命令。
