Hi!
Regarding the previous thread about the DNS problems. I seem to
suffer (I think) the same configuration problems.
# nslookup myhost.dyndns.org
Server: localhost
Address: 127.0.0.1
Non-authoritative answer:
Name: myhost.dyndns.org
Address: 207.162.101.21
# nslookup localhost
Server: localhost
Address: 127.0.0.1
Name: localhost.dyndns.org
Address: 127.0.0.1
#
The fact that I have a dynamic IP, and that I use dyndns.org services
sure gives me trouble, but there's surely a way to get over this.
Is there some good DNS tutorial or doc out there?
I have the following relevant config in named and such:
/etc/resolv.conf:
nameserver 127.0.0.1
/etc/namedb/named.conf:
options {
directory "/var/namedb";
};
zone "." {
type hint;
file "named.root";
};
zone "0.0.127.IN-ADDR.ARPA" {
type master;
file "localhost.rev";
};
logging {
channel sys_secure {
syslog auth;
severity info;
};
category default { default_syslog; default_debug; };
category security { sys_secure; default_syslog; default_debug; };
};
/var/namedb/localhost.rev:
; From: @(#)localhost.rev 5.1 (Berkeley) 6/30/90
; $FreeBSD: src/etc/namedb/PROTO.localhost.rev,v 1.4.2.1 1999/08/29 14:19:29 pet

@ IN SOA myhost.dyndns.org. root.myhost.dyndns.org. (

1 IN PTR localhost.
root IN CNAME localhost
localhost. IN A 127.0.0.1
oh... and:
/etc/host.conf
# $FreeBSD: src/etc/host.conf,v 1.5.2.1 1999/08/29 14:18:44 peter Exp $
# First try the /etc/hosts file
hosts
# Now try the nameserver next.
bind
# If you have YP/NIS configured, uncomment the next line
# nis
/etc/hosts
# $FreeBSD: src/etc/hosts,v 1.9.2.1 1999/08/29 14:18:44 peter Exp $
127.0.0.1 myhost.dyndns.org localhost
For the time being, I have disabled named (partly because of the
latest security concerns about it) and put my ISP's nameservers in
/etc/resolv.conf
However, I'm still wondering which 'domain' to put into
/etc/resolv.conf, since "myhost.dyndns.org" gives me:
$ nslookup localhost
Server: my.isp.org
Address: 123.456.789.123
*** my.isp.org can't find localhost: Non-existent host/domain
$
Thanks for any input or redirection.
AnarCat.
