I run my own NTP server, which can be reached with both IPv4 and IPv6. However, when I check with Wireshark, I see NTP requests going not only to my server, but also to an IPv4 address on the Internet. This happens with both my desktop system and ThinkPad, but they have different external addresses, in addition to my server. I use the host name for the server address in NTP Configuration.
Any idea where that other address comes from?
Are you running chrony or ntpd? Check /etc/ntp.conf or /etc/chrony/chrony.conf. Also check in /etc/chrony/chrony.conf.d because files in there are automatically included in chronyd's list of sources by default. If you're running systemd-timesyncd, then you'll have to check its default config files, and I've really no idea where they live. I disable/uninstall that and install chrony on all the machines I manage at work or at home. Hope this helps. -- ============================================================================== ============================ Rodney Baker rodney.baker@outlook.com.au ============================================================================== ============================
