Q. InterMapper Flows displays a list with columns for Client and Server. How does it determine which host is which?

A. InterMapper Flows uses a heuristic rule to determine whether a host is operating as a client or server:

* There is a built-in list of common Server ports. If a host is using an entry in the list, it is treated as the server.
* If there is no match with a common Server port, the lower-numbered port is treated as a server.
