VSFTPD的非常有用的权限控制语句
也许在使用FTP的过程中，可能是有一些权限控制的不如意，那下面我给大家提供的希望能对大家有用！
我们首先来看看下面的几个例子：
1、只能上传。不能下载、删除、重命名。
cmds_allowed＝FEAT,REST,CWD,LIST,MDTM,MKD,NLST,PASS,PASV,PORT,PWD,QUIT,RMD,SIZE,STOR,TYPE,USER,ACCT,APPE,CDUP,HELP,MODE,NOOP,REIN,STAT,STOU,STRU,SYST
2、只能下载。不能上传、删除、重命名。write_enable=NO
3、只能上传、删除、重命名。不能下载。download_enable＝NO
4、只能下载、删除、重命名。不能上传。
cmds_allowed=FEAT,REST,CWD,LIST,MDTM,MKD,NLST,PASS,PASV,PORT,PWD,QUIT,RMD,RNFR,RNTO,RETR,DELE,SIZE,TYPE,USER,ACCT,APPE,CDUP,HELP,MODE,NOOP,REIN,STAT,STOU,STRU,SYST
以上的2、3两点好控制，可是1和4就不是那么好控制了！
我给出了1和4的方法，当然，大家也可以说说自己是如何实现1和4的控制的，我们相互交流！
下面我就把具体的一些参数来和大家说说！
CWD - change working directory 更改目录
LIST - list remote files 列目录
MKD - make a remote directory 新建文件夹
NLST - name list of remote directory
PWD - print working directory 显示当前工作目录
RETR - retrieve a remote file 下载文件
STOR - store a file on the remote host 上传文件
DELE - delete a remote file 删除文件
RMD - remove a remote directory 删除目录
RNFR - rename from 重命名
RNTO - rename to 重命名
以上是常用的一些参数，大家对照学习一下！下面是列也的全部参数，供大家参考！
