parker可以正常使用，但有的FTP搜索不了，请教

skyone

我的parker安装正常，且也能搜到东西，但为什么有的FTP它搜不到东西？我在etc/Parker_Hosts加入了肯定存在并支持匿名的几个FTP，执行bin/NewDate后，从屏幕的回显来看，有的能搜到东西，有的又不能， 请教是怎么回事？下面是一个正常的匿名FTP，NewDate数据更新时显示的结果，

我看到这几行是正常FTP没有的
550 ls-lR: The system cannot find the file specified.
550 /pub: The system cannot find the file specified.
550 /pub: The system cannot find the file specified.
550 /pub: The system cannot find the file specified

但我用ftp命令登陆到这个FTP，可以执行ls -lR,且可以正常返回文件清单
