# This is a basic ProFTPD configuration file (rename it to
# 'proftpd.conf' for actual use.  It establishes a single server
# and a single anonymous login.  It assumes that you have a user/group
# "nobody" and "ftp" for normal operation and anon.

我想起的作用：tester用户在/data/system/ftp/test目录下只能上传，不允许删除，改名，下载，但实际情况是可以上传，删除，下载，等同于这个限制不起作用，不知哪里出现了语法错误。请指点。
