Yes, I can confirm your finding. Namely these 88.* belonging to Turk Telecom and bunched into their subnets. Just as much as they fly in, as well they disappear. Just a note. The monlist can trace only 600 clients at any instant. Very useful are the scripts written by Wayn Schlitt. However, their load is a few times higher than that of the ntpd itself. -- Karel Sandler _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
