nmap reports as expected when scanning the actual ip address, but when run
against localhost various open ports show up.

Any ideas ?

Starting nmap V. 2.54BETA29 ( www.insecure.org/nmap/ )
Interesting ports on localhost (127.0.0.1):
(The 1540 ports scanned but not shown below are in state: closed)
Port       State       Service
21/tcp     open        ftp
22/tcp     open        ssh
53/tcp     open        domain
80/tcp     open        http
443/tcp    open        https
1669/tcp   open        netview-aix-9
