| By default, Cassandra uses 7000 for cluster communication (7001 if SSL is enabled), | |
| 9042 for native protocol clients, and 7199 for JMX. | |
| The internode communication and native protocol ports are configurable in the Cassandra Configuration File. The JMX port is configurable in cassandra-env.sh (through JVM options). All ports are TCP. | |
| 127.0.0.1:9042 | |
| nc -vz 127.0.0.1 9042 | |

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.
ssh, ssh-add and ssh-keygen on most computers
