ftp ftp.test.com 输入了用户名和密码报了错如下

ftp> ls
500 Illegal PORT command.

ftp: bind: Address already in use

然后解决如下

ftp> quote pasv
227 Entering Passive Mode (192,168,0,112,164,248).
ftp> passive
Passive mode on.

然后ls还是报错

ftp> ls
227 Entering Passive Mode (192,168,0,112,169,241).

425 Security: Bad IP connecting.

这个原因是因为服务器本身设置了两个ip地址

解决办法是

vim /etc/vsftpd/vsftpd.conf
添加：pasv_promiscuous=YES
保存后退出

重启vsftpd #service vsftpd restart

ftp> quote pasv
227 Entering Passive Mode (192,168,0,112,143,83).
ftp> passive
Passive mode on.
ftp> ls
227 Entering Passive Mode (192,168,0,112,85,218).
