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

any help??? Tnx
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.
