很多用户们在ubuntu下都不知道如何用proftpd来构建ftp服务器,接下来的我们就跟爱站小编一起去学习ubuntu下用proftpd来构建ftp服务器的方法。

1- 使用下面的命令安装proftpd:

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) :

/bin/false

新建一个 /home/FTP-shared 目录 :

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:

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:

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:

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:

sudo gedit /etc/proftpd.conf

当然你可以按你的需要编辑你自己的proftpd.conf:

# 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

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

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

# 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

# Display a message after a successful login

# 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

/home/FTP-shared/upload/>

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:

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:

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.
