问题描述
我在建立一个FTP东西的基础上，我注意到
它只会在我有效的情况下工作chmod文件夹777，我想要记住
正确，以前在另一个网站chmod 744就够了，
现在它不是。
$ b $我错了，它应该永远是777吗？并且不是chmodded
777文件夹更容易受到攻击？

Hi,
I am at the base of an FTP thingy i''m building, and i noticed that
it would only work if i chmod the folder 777, i thought to remember
correctly that previously on another site chmod 744 was enough,
now it isn''t.
Am i mistaking, and should it always be 777 ? And isn''t a chmodded
777 folder much more vulnerable?
