我将vsftpd移植到在Linux 3.0.8内核下运行的基于ARM的主板上。
当我尝试使用Filezilla（3.7.3）建立与主板的ftp连接时，出现以下错误：
Status: Connecting to XXX.XXX.XXX.XXX:21
Status: Connection established, waiting for welcome message...
Response: 220 (vsFTPd 3.0.2)

Command: PASV

我的服务器使用的配置如下：
listen=YES
max_clients=2
max_per_ip=4
# Access rights
anonymous_enable=YES
local_enable=NO
write_enable=NO
anon_upload_enable=NO
anon_mkdir_write_enable=NO
anon_other_write_enable=NO

pasv_min_port=0
pasv_max_port=0
# Features

ls_recurse_enable=NO

async_abor_enable=YES
# Performance
one_process_model=YES
idle_session_timeout=120
data_connection_timeout=300
accept_timeout=60
connect_timeout=60
anon_max_rate=50000
pam_service_name=vsftpd
port_enable=YES
log_ftp_protocol=YES
我的主板上没有安装防火墙。
当我强制ftp连接模式进入ACTIVE模式时，我可以连接到服务器，检索数据，上传文件......
我试过几个ftp服务器，但我总是遇到同样的问题。
知道可能是什么问题吗？
可能是因为缺少某些内核模块？
