All possibilities = 9! 
possibilities that harry sits at an end = 8! + 8! 
possibilities that harry doesn't sit at an end = 9! - 8! -8!

List of all possibilities, without restrictions (ie Harry can sit in any of the 9 seats): 9!
List of all possibilities where Harry sits on either end: 2 \cdot 8!

Hence, list of all possibilities where Harry doesn't sit on either end: 9! - 2 \cdot 8! = 282,240 ways.
