Hmm. Lots of view, no replies.
What I have learned so far is that at a minimum the dns has to support queries via host. That is, if the domain name of server is yourname.com you should be able to the following on a computer on your network using terminal:
Last login: Sun Jul 30 10:42:22 on console
Welcome to Darwin!
Hollands-Computer:~ steve$ host yourname.com
yourname.com has address 10.0.1.234
Hollands-Computer:~ steve$ host 10.0.1.234
47.1.0.10.in-addr.arpa domain name pointer dns.yourname.com.
Hollands-Computer:~ steve$
The above assumes the dns sever is named dns.
If there are opther tests of the DNS I’d appreciate hearing about them.
