Sure - just step into your time machine, go back to before the master server died, and increase the SOA.expire value there so that it gets propagated to the slave(s) in time. If your disaster recovery plan doesn't include use of a time machine, then you need to set SOA.expire large enough that you will have time to execute the next stage of the plan before the copies expire - convert a slave to be master, re-incarnate the master on new (possibly virtual) hardware, or whatever. BTW, there is an interaction with DNSSEC in setting a large SOA.expire value for a signed zone. You don't want your slaves to be serving expired signatures even if the zone copy is not expired, so you should arrange that resigning occurs at least the SOA.expire period before the old signature is due to expire. With BIND's defaults of a 30-day signature validity period and resigning 3/4 of the way through that, an SOA.expire period of 1 week works out quite nicely. -- Chris Thompson Email: c...@cam.ac.uk ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

[OT] MSDN use google apps for email hosting

Issues following 9.3.5-p1 upgrade to 9.7.0-p1 Windows VMware environment
We have been running Bind 9.3.5-P1 on Windows 2003 guest in VMware ESX 3.5 environment for many years with no issues. Following an upgrade to Bind 9.7.0-p1 we are experiencing a couple of issues. No Bind configuration changes were made to config files other than the allow-query-cache, additional-from-auth and additional-from-cache statements so that queries worked in the new version. The errors are occurring on multiple Bind servers on different Vmware ESX hosts. On a regular but random basis we are getting the 2 socket error messages logged. I have not been able to determine what is causing this to occur nor reproduce at will. .\socket.c:2444: unexpected error: SOCKET_RECV: Windows error code: 1236, returning ISC error 54 We are also getting a poked timer error logged consistently soon after Bind service start and infrequently after that. *** POKED TIMER *** Any suggestions / solutions would be greatly appreciated.
