Re: Secondary DNS

[Erich Schroeder <erich@museum.state.il.us>]

In your note you said that the secondary server was not getting updates, 
by that do you mean that you have been adding new entries to a 
/etc/named.data file on the primary server? If that is the case, do you 
update the serial number in the SOA record of the zone file? The SOA 
record of our primary server looks like this:

;*******************************************************
;  /etc/darwin.named.data
;
;  Zone file for the domain. Host to Address mappings.

@       IN      SOA     museum.state.il.us. erich.museum.state.il.us. (
                        1998071601      ;serial number(yyyymmddnn)
                        3600            ;refresh
                        3600            ;retry after 1 hour
                        3600000         ;expire after 1000 hours
                        2592000         ;default ttl
                        )

This is under AIX. When I add a record, I change the serial number, and 
then restart named. It then takes a while to get propagated throughout 
the world. The nameserver at Texas A&M gets it in an hour or so, UIUC may 
take a week.
