we have been running each school in our district (each one with its
own Mac OS X Server running Bind) as their own private DNS domain
(all forwarding to our network provider for public DNS):
You're running each school as a separate zone? Why not run one big
zone for all schools?
Because these schools were not connected together in any way until this month.
Forwarding to your network provider for what exactly? Zones not local?
Forwarding to their DNS servers for resolving all public domain
names. I know this is not necessarily the best way to do this, but
originally we did not want to have to worry about updating a bunch of
separate server's root hints files, so we set them all up as
forwarding servers, which is described as being acceptable in DNS &
Bind.
school.lan 10.10.1.0/24
school2.lan 10.10.2.0/24
etc.
Now the schools are connected in a WAN, but each still with the
same private subnet 10.10.X.0/24.
What's the best way to approach sharing the DNS info across these
domains, so that a lookup for ns.school2.lan is resolved on any
other schoolX.lan subnet?
Use zone transfers. Maybe use Views like you should be.
Wouldn't this mean that we would have to setup a separate zone for
each school domain on every server?
One master DNS server with a forward and reverse zone for each
domain, with a slave at each school?
Maybe, if you're a control freak and like to have central control.
You could just have them each do zone transfers tpo each other and
leave control for each zone local to each of these "schools".
Ok. I think that clarifies my last question. So setup each server to
do zone tranfers for it's own domain to every other server?
Of course why bother to have a DNS server in each school, sounds
like you just need one on your network that holds all the zones and
everything using it as
Again, just because we started with separate domains, so we currently
have ns.school1.lan and ns.school2.lan, etc. So if we change to one
domain, we would have to change each server's host name (not that
difficult, since there aren't that many static dns records anyway).
So, I take it you would recommend changing to one domain, and
changing some of the other servers to domain slaves for redundancy,
instead of doing zone tranfers with the multiple domains?
