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.  (
                                19991025        ; Serial
                                3600    ; Refresh
                                900     ; Retry
                                3600000 ; Expire
                                3600 )  ; Minimum
        IN      NS      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.
