To clarify: prior to 4.2.0 ntptrace was a C program which used the time messages. 4.2.0 introduced the perl script because using the time messages doesn't work with upstream IPv6 servers -- you can't tell whether the refid in a time message is an IPv4 address or a mashed IPv6 address. _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
