Hi, Each node needs two ports to be fully functional - one for discovery and one for communication.
Both TcpDiscoverySpi and TcpCommunicationSpi have two configuration properties: localPort and localPortRange. When choosing a port to bind to, each of these SPIs starts from the localPort and then successively tries others until it finds an available one. By default, local port for discovery is 47500 and 47100 for communication. Default range is 100. So with these settings a node can bind to any port in range 47500-47600 and 47100-47200, but you can tweak this by changing the properties mentioned above. Does this make sense for you? -Val -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/list-of-ports-used-tp737p740.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
