Как узнать, какая служба использует порт?
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.6 (Maipo)
# netstat -natpv | grep 9090
tcp6 0 0 :::9090 :::* LISTEN 1/systemd
#
Пожалуйста, порекомендуйте.
# systemctl status cockpit.service

не идеально, но лучше тогда ничего:
# systemctl | grep listening
dm-event.socket loaded active listening Device-mapper event daemon FIFOs
iscsid.socket loaded active listening Open-iSCSI iscsid Socket
iscsiuio.socket loaded active listening Open-iSCSI iscsiuio Socket
lvm2-lvmpolld.socket loaded active listening LVM2 poll daemon socket
systemd-initctl.socket loaded active listening /dev/initctl Compatibility Named Pipe
systemd-shutdownd.socket loaded active listening Delayed Shutdown Socket
virtlockd.socket loaded active listening Virtual machine lock manager socket
virtlogd.socket loaded active listening Virtual machine log manager socket

в моем случае это было cockpit.socket (не cockpit.service)
systemctl list-sockets должно отображать точное название объекта и соответствующую услугу.
