Re: some permission problem?

["SB CH" <chulmin2 () hotmail com>]

Thanks again for all your kind answer.

But there is another way like some other user's file include /etc/passwd, 
like dbconn.inc which contains a username and password of the db(like 
mysql. oracle...)  in web hosting server.

As a matter of fact, anyone can read these files easily using fileopen() 
like perl or php function by web. 
Is there any method against this attack?


Thanks again.
