Rogue Wave® Server provides a logical mapper, named tcpd, which must run on each machine that runs a server or a named component (for example, if you give a name to a component using the -ilsn command line option).

This logical mapper stores associations between named servers and the TCP ports they are using. The component connects to the server as follows:

By default the Rogue Wave Server logical mapper is designed to listen on the TCP port 8000, but you can change this default value by setting the environment variable ILS_TCPD_LISTEN_PORT on the machine running the daemon and on the client machine. You can also use the command line option
