First in /var/log/messages: Mar 9 11:09:09 c7tst ntpd[8238]: Listen and drop on 0 v4wildcard 0.0.0.0 UDP 123 ¿¿???? And second: ss output shows an "UNCONN", that means "unconnected" .... Uhmmm, and I don't understand why .... There is no firewall or blocking gateway between this C7 vm and Internet ...
