flashfxp 最近连linux发现使用选项mlsd列表错误 报"[右] 500 Illegal PORT command.
[右] 列表错误"

  试了下用stat -l选项正常显示了;

   查询了命令发现:LIST

This is the normal list method.
 正常的列表命令
LIST -al
This is a normal list with additional parameters which instruct the server to include hidden files.
列出所有文件(包括隐藏的)
MLSD
MLSD is a new FTP command intended to provide detailed, standardized machine readable directory listings across different server platforms. 
Note: Most servers do not show hidden files when MLSD is selected. If MLSD is not supported FlashFXP will fall back to LIST or LIST -al.
MLSD是一个新的FTP命令 为了对跨平台的进行读取文件目录；大部分服务器使用mlsd不显示隐藏的目录。若mlsd不支持，则返回到LIST LIST -al
STAT -L
Similar to LIST above, however the directory listing is sent via the command channel. This eliminates the need for opening a data connection. This can speed up things up by a couple of seconds on a slow connection.
Note: Not very many servers support this command.

和MLSD类似，不打开数据连接.可以加速低链路连接；

估计是我的linux防火墙对数据通道连接进行了阻止。导致了数据连接不能建立；
