I have a machine with Debian Linux 2.0 installed and I am trying to
configure it as a DNS server. This machine is not connected to the
Internet, for now I am only using it to create a Intranet. My LAN as a
class A address with a mask of 255.255.0.0. in order to have various
sub-networks.
The configuration file are as follow:
1. /etc/named.conf
// generated by named-bootconf.pl
options {
directory "/home/carmen/named";
forwarders {
10.70.108.250;
};
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
//
// Boot file for name server
//
// type domain source file
//
zone "." {
type hint;
file "named.root";
};
// Zone boot information and daemon options are kept in other files
// (autoincluded from boot.zones)
//
// Name server zone boot file
// See named(8) for syntax and further information
//
// type domain source file
// (autoincluded from boot.options)
//
// Options for name server
// Use `bindconfig' to automatically configure this file
//
// type domain source file
zone "localhost" {
type master;
file "named.local";
};
zone "0.0.127.in-addr.arpa." {
type master;
file "named.rev-local";
};
zone "hph.min-saude.pt" {
type master;
file "hph.hosts";
};
zone "70.10.in-addr.arpa." {
type master;
file "hph.revhosts";
};

With this configuration files I get a error message in
/var/log/daemon.log as follow:
Nov 23 15:26:06 linux named[8195]: sysquery: no addrs found for root
NS ()
Nov 23 15:26:37 linux last message repeated 4154 times
Nov 23 15:27:38 linux last message repeated 8174 times
Nov 23 15:28:39 linux last message repeated 8174 times
Nov 23 15:29:02 linux last message repeated 3198 times
How can I fix the problem in order to avoid this messages ?
I would like that you recommend me a book or some other kind of
documentation in this matter, because it is the first time I am
confronted with this problem and I have no background in this matter.
The configuration files listed in this letter were made based on a
article by Tom Yager that I collect in the Internet at
www.networkcomputing .com/unixworld for a class C network.
I wonder how I can define hosts in a sub-network different from 10.70.
Thank you for any help you can give to me,
Carmen
