I currently have an application running on Ultrix which uses TCP/IP. Each machine in the network has a server running on it. The server is opened in passive mode and listens at a known port for traffic. Under Ultrix this "known port" is defined by adding an entry for my server into the file /etc/services. How is this done under VMS? How are the well-known ports defined? Or does this depend on the TCP/IP software you have?

On MultiNet you add an entry to a text file which gets compiled into a binary database and loaded into a global section for fast access. On WINS/TCP I believe that you add an entry to the etc:[000000]services file just like under Unix. Well known ports don't HAVE to be defined in these files, it just makes it convenient because your code can reference the port by name instead of number. Kenneth Adelman TGV
