setUID problem

jcadam007

As I just want to test the function of setUID , i wrote a script named "test.sh" following with root:

#!/bin/bash
mkdir /root/Test

setUID: chmod +x test.sh
the mode of the file now
   -rwsr-x-r-x
it will do the trick when i use it with root but failed with the other user.
Display
"Creating /root/Test Pemission Deny"
What the matter??? Why???
I puzzled.

兄弟能找找资料说下如何才能让setuid的脚本可用吗?

我一直以为是像楼主那样做.请指点

另外,脚本setuid是很危险的其中缘由可参看下面这个链接:

Linux doesn't support this since it is insecure.  It works with perl
scripts only, because Perl does some extra checks and explicit handling to
make it work.

To get a setuid shell script you have to write a C wrapper program for it
or let the user execute it with sudo.

呵呵，和我找到的资料说法是一样的，在Linux这样和系统setuid是不起作用的，但在一些UNIX系统则可以起作用，此时要非常注意安全
