Well in advance of the change, set your TTLs very low. tinydns can dynamically adjust TTLs and automatically switch between two IP addresses at a specified time. This will help eliminate down time, but won't work for everything, as some DNS caches do not respect low TTLs. The only solution is to have the affected services operating on both sets of IP addresses during the transition period. This can be difficult, but it is a requirement. You normally have no way to control the TTLs on your name server glue records. Your procedure is overly complex because you should not have to rename your name servers. Setup name service on both sets of IP addresses. Serve the old addresses from the old name servers and new addresses from the new name servers. Then simply update the IP addresses of the name servers with your registrar (which updates these glue records with the registry). -- David Phillips <david at acz.org> http://david.acz.org/ _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
