On my home network, I have my firewall providing NTP and in turn connecting to a public NTP server. I access my firewall NTP server by host name, which will return both IPv4 and IPv6 addresses. In watching the NTP traffic between my desktop computer and firewall, I see both IPv4 and IPv6 addresses alternately being used. Is this the way the NTP client normally works? I could understand it trying multiple addresses, if that is what I provided, but I only provide a single host name, that returns both IPv4 and IPv6 addresses. Normally, with other apps, IPv6 is preferred over IPv4. I have never looked at the traffic, only at the output of 'ntpq -pn' - sometime I see ipv4, some times I see ipv6.
I have also noticed sometimes I get 2 IPv6 requests in a row, but haven't seen 2 IPv4 yet. It's not a problem, but I am curious as to why it happens, when normally IPv6 is preferred. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
