I am using a desktop where I have connected a printer: if I enable the firewall I can connect by IP numbers and print if printer is nameofprinter@IPof desktop (the same with vinagre, i can connect by IP numbers and not by names): the only way to print (and connect by names in vinagre, and share Public Files) is to have firewall stopped. This is my firewall configuration: FedoraWorkstation (default, active) interfaces: p19p1 sources: services: dhcpv6-client dns ipp ipp-client mdns samba-client ssh ports: 1025-65535/udp 1025-65535/tcp masquerade: no forward-ports: icmp-blocks: rich rules: any help???

You have a DNS resolution issue. With the firewall enabled, as root, try: # iptables -L -n | grep :53 and make sure you see lines like: ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:53 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:53 to ensure you can do DNS. These don't normally show up under the firewall GUI. If they are NOT open on your machine, then open them in the firewall GUI and reload the firewall. Also make sure avahi-daemon and dnsmasq are running. Avahi-daemon is generally run via # systemctl start avahi-daemon.service dnsmasq is usually started by the libvirtd service if you have virtualization installed. If not, it can be started via # systemctl start dnsmasq.service If you've had to start either, then also # systemctl enable <name-of-service> to make sure they start on the next reboot as well. ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 226437340 Yahoo: origrps2 - - - - You know you've landed gear-up when it takes full power to taxi. - - -- Chuck Yeager - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
