ProFTPd 14.04 - 503 错误

配置文件很简单，我对 ProFTPd 的要求不是太多，而且已经设置了所需的参数。

    ServerName          “uk.domain.com"
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                nobody
Group               nogroup

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

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

用户已设置 /bin/bash shell。ProFTPd 默认为 nobody、nogroup 等。端口 TDP 和 UDP 在 21 上打开，入站和出站。任何帮助都将不胜感激！！

您的配置中没有定义任何指令。您需要创建一些供 Proftp 使用的指令。手册页将帮助您完成此操作。

这是您正在寻找的配置：

## Includes required DSO modules. This is mandatory in proftpd 1.3
# Include /etc/proftpd/modules.conf

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

AuthPam on    # Uses unix authentication.
