How to realize the experiment on nosuid
 

I had two linux (Suse v10.2)
One was as a server
One was as a client
Client mounted the shared folder with suid
/etc/exports in the server was rw,sync
And there was an ls file in it with suid set
-rws------ 1 root root 79944 Sep 13 06:11 ls
So I wanted to execute ls file by ./ls
But it said no permission
Then how could I realize the experiment on suid ?
Thanks!

The default export option is root-squash, to prevent security holes; http://linux.die.net/man/5/exports
