Sprinter uses ports:
Default Ports
8080 (11.5x)
8085 (12.x and higher).
Range from 9000 to 9009. If any of these ports are unavailable in your organization, some Sprinter functionality will not work. For example, when trying to connect to a mirror machine, the error message ''Could not find the machine on the network'' will be displayed if these ports are blocked.
About ports enable HP ALM to communicate with Sprinter. It also uses ports when in Power Mode to work with your primary machine and to communicate with your secondary machines when using mirroring feature.
