When I try to apply any permanent changes to firewalld rules I get the following:
pc services # firewall-cmd --permanent --zone home --remove-service samba-client
Error: INVALID_SERVICE: 'mdns' not among existing services


thanks

What are those rules you set? Are you trying to configure firewall with service names instead of ports?
Do you have mdns in your /etc/services?
Quote:
$ grep mdns /etc/services
mdns 5353/tcp # Multicast DNS
mdns 5353/udp
mdnsresponder 5354/tcp noclog # Multicast DNS Responder IPC
mdnsresponder 5354/udp noclog # noclogd with TCP (nocol)

that is the only rul I have tried so far:
firewall-cmd --permanent --zone home --remove-service samba-client
yes , if I use the service name:
pc tiny # firewall-cmd --add-port 8080/tcp --permanent
Error: INVALID_SERVICE: 'dhcpv6-client' not among existing services

and yes both services are in /etc/services



thanks

solved by removing the services from the public zone

firewall-cmd --zone=public --remove-service dhcpv6-client --permanent
firewall-cmd --zone=public --remove-service mdns --permanent
