It seems my problem to begin with was that my new server was not a yp server
(master or slave). SunOS 4.1.3 requires the DNS "resolver" to be a server but
there are ways around this.

1) Modify the library. This makes your system a DNS name server
and you must that configure as such. Sun provided me with the procedures to
modify but they do not support it.

2) Make your server a slave server.

3) Create a new domain and make the new server its master.

I chose option 3 and here is why;

I tried option 1, it work fine for seeing my Internet name servers but I
could not get it configure correctly so that it could see my local systems
(one usually in /etc/hosts). The sys. admin manual also indicates that for
each DNS zone there should be at least 2 name servers, a primary and a
secondary. I don`t have two servers connected to the Internet and really
I need to be is a resolver, looking in my host file or Internet name server.

I didn't want to my server to be a slave yp server to my local network for
security (firewall) reasons. I'm trying to isolate the server as much as

I ended up using option 3, which also ended up be the easiest. I created
a new domain and made the server a master on one domain and my old server
the master of my local domain.

Thanks to Phil Blanchfield (, I modified my Makefile
on the new server to include only my local hosts and "B=-b". So far
so good.

Several people suggested resolv+. If you have more info on this, I would
like to hear from you.
