Red Hat Summit1.5. Predefined firewalld services
Predefined firewalld services offer an abstraction layer for low-level firewall rules. They map common network services, such as SSH or HTTP, to their specific ports and protocols, simplifying firewall management and reducing errors by using a named service instead of manual configuration.
To see available predefined services:
# firewall-cmd --get-services RH-Satellite-6 RH-Satellite-6-capsule afp amanda-client amanda-k5-client amqp amqps apcupsd audit ausweisapp2 bacula bacula-client bareos-director bareos-filedaemon bareos-storage bb bgp bitcoin bitcoin-rpc bitcoin-testnet bitcoin-testnet-rpc bittorrent-lsd ceph ceph-exporter ceph-mon cfengine checkmk-agent cockpit collectd condor-collector cratedb ctdb dds...To further inspect a particular predefined service:
# sudo firewall-cmd --info-service=RH-Satellite-6 RH-Satellite-6 ports: 5000/tcp 5646-5647/tcp 5671/tcp 8000/tcp 8080/tcp 9090/tcp protocols: source-ports: modules: destination: includes: foreman helpers:The example output shows that the
RH-Satellite-6predefined service listens on ports 5000/tcp 5646-5647/tcp 5671/tcp 8000/tcp 8080/tcp 9090/tcp. Additionally,RH-Satellite-6inherits rules from another predefined service. In this caseforeman.
Each predefined service is stored as an XML file with the same name in the /usr/lib/firewalld/services/ directory.
