Cassandra port overview:
Public port.
22 SSH port
Cassandra inter-node ports.
7000 Cassandra inter-node cluster communication.
7001 Cassandra SSL inter-node cluster communication.
7199 Cassandra JMX monitoring port.
Cassandra client ports.
9042 Cassandra client port.
9160 Cassandra client port (Thrift).
9142 Default for native_transport_port_ssl, useful when both encrypted and unencrypted connections are required
Likely the port you are looking for is port 7000.
