	They were/are a lots of ways to break into any

	this is what Unix security is about.

: On the system in question, no terminals are marked "secure" except the

: it is of course possible.

	Hackers usually break into the system using other ways,
	Get yourself book on generic Unix security - O'Reilly
	has some, subscribe and read thru CERT advisories , 
	get rid of setuid bits in files your never use , mount users
	homes with No-SUID or No-exec , wrap up services with
	tcpwrappers, write logs to secure machine etc .

               In the world of magnets and miracles
               Our thoughts strayed constantly and without boundary
               The ringing of the division bell had begun ...
