[jira-272] This script is to check whether the ports required to run SEBA services are already being used by other application before installation of SEBA. If no ports that we require are already used then this script will reserve all the required ports on the OS, so that these ports will not be assigned by the OS to any other services later. If ports we need are already used, then execution of make will be terminated with error code 255.
