What is service mysqlx?

Why is it not mapped in /etc/services?

$ cat /etc/services | grep mysql
mysql 3306/tcp
mysql 3306/udp
mysql-proxy 6446/tcp # MySQL Proxy
mysql-proxy 6446/udp

Why is it not part of the command for the process?

$ ps -A | grep mysqlx

Is it possible that nmap can report misleading information? Do you find out the services running on the local machine not by nmap?

Thanks.

The mysqlx service on port 33060 is the MySQL X DevAPI service.

nmap does not use /etc/services, it uses its own database of services.

Note that anything listening on port 33060 will be reported as the mysqlx service, and that the name of a service does not necessarily have to be part of the name of the command providing the service (both exim and postfix may provide an smtp service, for example).

To see what's listening on port 33060 on the local machine, you may use, on a Linux system,

sudo lsof -i :33060

or

sudo fuser -v 33060/tcp
