|
| Ted, you disappoint me. :)))
|
| When the slave transfers the zone file, AND loads it (I´ve never heard of
| the two operations NOT occurring in conjunction, have you?), named will log
| the name of the zone and the new serial number as it loads into
| authoritative memory. Can´t get much better guarantee than that.
|
| >The very best way to test that the secondary is in operation WITHOUT

|
| you´re having a bad day, Ted!! :))
|
| After looking in the slave´s named.run log file to confirm the zone has
| transferred and loaded, doubting Thomases can do this:
|
| dig @slave.dns zone.in.question SOA
|
| and see immediately if the SOA s/n is same as on the master. Using the
| "readable" ccyymmddxx format for the serial number facilitates checking.
^^^^^^^^^^
What is the cc in this case. I must have missed that in the book. My
serial numbers are of the format yymmddxx only ;-)
And to get more into this mix, I found this in my logs:
26-Aug-2001 12:32:38.622 MAXQUERIES exceeded, possible data loop in
resolving (www.symantec.com)
What the heck is MAXQUERIES and why is it being exceeded?
Thank you gurus!!
