single entry to hosted service

[Jeff Lightner]

You create a zone file that only has the entries for accounting.com.  You add that to named.conf.  

Your other zone files are still in place so you shouldn't need to forward anything else because you're saying this is internal to your network.  If a user is sitting at his desk and types:

InternalSite1.excample.com to get to one of your internal websites then goes to hosted.accounting.com then tries to go to InternalSite2.example.com then their current stub server setting should use the same resolution setting (e.g. /etc/resolv.conf on UNIX/Linux) to get to InternalSite2 as it used to get to InternalSite1.

The above assumes all your workstations etc... always ask your DNS server for any lookup first which is the normal way of doing things.

Yes I do need some kind of dns configuration.  We bought a hosted
accounting service from a company that has asked us to put a dns entry
into our dns servers so that our internal machines only can resolve
there hosted service via dns.  I guess they don't want to populate
there isp's dns servers with all of the dns entries for all of there
customers....

So with my limited knowledge of bind (using webmin to configure it) I
need to make an entry like this:

222.222.222.222  A  hosted.accounting.com

In our internal DNS servers.

I don't have any "internet side" dns, just internal.  I'm just a bit
unsure on what the best way to do this is, and I don't want to have to
append everyone's hosts file on there workstations.  I have many
master zones for our internal systems, and I have created all of the
nessesary records.  I have setup slave servers, and the whole bit.

So i'm wondering do I need to setup a master zone, and put in the
222.222.222.222 A hosted.accounting.com as an A record, and then have
the zone forward everything else?  Reason being is because our users
will still need to access other sites from the accounting company's
domain.


Thanks,
Dan.
