firewalld: list of ports versus services

jvlbe · April 3, 2020, 3:58pm

Hi,
Is it possible to get a list of ports related to services so that I can use the services instead of ports to open up?
thanks

Hi
The services and ports are in the file /etc/services (or /usr/etc/services).

firewall-cmd --service=*service *--get-ports

If you are asking, is it possible to query which service includes given port - I do not think it is possible via command. You would need to parse service definitions directly or list all services and then for each service list ports and check whether your port matches.
