The router service entry in the /etc/services file has the following syntax:
router_service router_port/tcp # commentThe optimal /etc/services router service entry is:
ccm7.2_router 5412/tcp # Rational Synergy router port
The first column is the service name, which must be ccm7.2_router. The second column starts with the port number, which can be any deallocated, unreserved port. On most systems, port numbers in the range of 0 to 1023 are reserved (privileged). If port 5412 is not in use, use it because it is reserved for Rational Synergy by the Internet Assigned Number Authority (IANA).
You need this information during installation. If you do not have a dedicated port defined when you install Rational Synergy, the installation program prompts you to choose one.
