samba on port 445 too?

We run smbd out of inetd, listening on port 139. Should we also have
inetd start smbd for connections on port 445?

It depends. Port 139 is used for SMB using the old NetBIOS over TCP/IP
protocols. This is used by Windows 9x/Me, DOS, OS/2, and various older SMB
implementations, as well as by newer systems for compatibility. Newer
systems, including Windows XP/200x and recent versions of Samba, can use
either NetBIOS over TCP/IP on port 139, or they can optionally use a more
direct method of connection using port 445. If you're using older clients
exclusively, then there's no point to activating port 445 access. If
you've got newer clients, then providing both enables the client to choose
which method to use. The port 445 method enables some additional features,
which are mostly performance-related. I don't know of any benchmarks
testing the speed of these methods, though, so I don't know how important
these features are in improving performance.

139 is a NetBIOS port (Used for NetBIOS name resolution)

445 is SMB (Server Message Blocks) itself.
