/*
 *	This command enables a user to break a connection that
 *	that has been made by 'log'.
 *	Also could be used to stop 'watchers' !!
 *	The argument to this command is merely the name of either
 *	special file that was involved in the redirection.
 *	This command like log must also be set-uid to root so that
 *	the connect system call will work.
