DNS Config

[Nash Computer Technology]

Hello

Following on from previous posts, I'm trying to configure a primary - slave
DNS. I've discovered that the SCO documentation doesn't cover OpenServer
5.0.5 which uses /etc/named.conf. However, even after looking through the
new sample files in /etc/named.d, I haven't a clue what to do. Is there
somewhere that describes what to do? I want my server to provide local DNS
services, then to use my ISP's DNS for external Names.

Thanks again

You can follow the instruction in many books out there, two come to mind:
DNS and BIND, TCP/IP both by O'Reilly (excellent books)

Then you can run the shell script provided with SCO 5.0.5 in the
/etc/named.d directory, it will generate the named.conf file for you

Hope this helps

Such a simple thing to want, yet such a pain to set up...

I will post my DNS files, and which you can then bastardise them as you see
fit. You might also want to get a copy of nslint, which is a DNS file checker,
and is quite handy for picking up typos!

; /etc/resolv.conf
hostresorder local bind
domain yourdomain.com
nameserver 127.0.0.1

;
; /etc/named.boot
;
directory /etc/named.d
cache . root.cache
primary yourdomain.com named.hosts
; replace the following with whatever local IP network address you're using
primary 1.168.192.in-addr.arpa named.rev
primary 0.0.127.in-addr.arpa named.local
; replace the following with each and very DNS server your ISP has
forwarders 0.0.0.0 0.0.0.0

Don't do anything with the root.cache file. That's happy.

; /etc/named.d/named.soa
@ IN SOA yourdomain.com. root.yourdomain.com. (
19991005; Serial
10800 ; Refresh
1800 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS dns-server.yourdomain.com.

Obviously replace root.yourdomain.com with the mail address of whoever is
maintaining the DNS (I think, but don't quote me), and dns-server with
whatever the DNS is. This may be a "real" machine name, or an alias which is
what I have done. Nslint does whinge about too many aliases. You'll need to
change serial everytime you make a change to any of the files in /etc/named.d.

; /etc/named.d/named.local

$INCLUDE named.soa
1 IN PTR localhost.

; /etc/named.d/named.hosts

$INCLUDE named.soa

localhost. IN A 127.0.0.1
yourserver IN A 192.168.1.3
alias IN CNAME yourserver
yourserver IN MX 0 mailrelay
yourdoamin.com. IN MX 0 mailrelay

Obviously mailrelay should be a machine!

; /etc/named.d/named.rev

$INCLUDE named.soa

3 IN PTR yourserver.yourdomain.com.

Add other machines into named.hosts and named.rev as you see fit! Enjoy!
