TLD Resolving Woes

Hi folks,

I've recently migrated from an ISP that handled my DNS services to one
that does not. I've muddled my way to a semi-working configuration, but
have basically hit a roadblock, and was wondering if someone can help me
get to a proper configuration.

Basically, I want to set up primary and secondary DNS and MX for my
domain, on ns1.progressivetrail.org and ns2.progressivetrail.org.

The configuration that I have set up will resolve basically any wildcarded
second-level domains (e.g., scoobydoo.progressivetrail.org), but not the
tld, progressivetrail.org by itself.

How do I need to modify this configuration so that progressivetrail.org
will resolve?

; zone file for progressivetrail.org
;
$TTL 3D
@ IN SOA ns1.progressivetrail.org.
root.progressivetrail.org. (
200303301 ; serial#
3600 ; refresh, seconds
3600 ; retry, seconds
3600 ; expire, seconds
3600 ) ; minimum, seconds
;

NS ns1 ; Inet Address of nameserver
progressivetrail.org. MX 10 mail ; Primary Mail Exchanger ;
localhost A 127.0.0.1
jefferson A 67.19.14.187
ns2 A 67.19.14.188
mail CNAME jefferson
ns1 CNAME jefferson
www CNAME jefferson
* CNAME jefferson

See the DNS HOWTO. If you want to resolve the domain alone, add an entry
for the domain ending with trailing dot (progressivetrail.org.) pointing
to an IP.

However, you have another potential problem. Any MX record should point
to an A record. You have it pointing to a CNAME which can cause a
recursive loop (MX points to CNAME, server looks up MX for CNAME which
points back to CNAME, infinitely). So make mail an A record (pointing
more than one A record pointing at same IP is not a problem). I use
dynamic DNS (no-ip.com) and its wildcard is an A record.

IIRC one does not use a CNAME for the mail (DNS and BIND 3rd Edition -
page 97) due to the possibility of running the risk of having your mail
loop, it may bounce the mail with the error:

554 mx list for domain.com points back to relay.isp.com
554 <(E-Mail Removed)>.... Local configuration error

This replaces the quainter "I refuse to talk to myself" error. The moral
in a MX record. always use the mail exchanger's canonical name.

I do relalize that the DNS and BIND 3rd Edition is a wee bit outdated
(1998) Perhaps someone smarter than me may have some insite

you also need an "A" record for progressivetrail.org

progressivetrail.org IN A 69.19.14.xxx

I also see that you are missing the 'IN' in your above record. Here is
an example of mine.

$ttl 38400
lbcclug.org. IN SOA ns0.findmoore.com. admin.lbcclug.org. (
2004112115
10800
3600
604800
38400 )
lbcclug.org. IN NS ns0.findmoore.com.
lbcclug.org. IN NS ns1.findmoore.com.
lbcclug.org. IN MX 5 mail.lbcclug.org.
ftp.lbcclug.org. IN CNAME lbcclug.org.
lbcclug.org. IN A 69.33.241.53
www.lbcclug.org. IN A 69.33.241.53
mail.lbcclug.org. IN A 69.33.241.53
69.33.241.53.lbcclug.org. IN PTR lbcclug.org.
69.33.241.53.lbcclug.org. IN PTR www.lbcclug.org.
69.33.241.53.lbcclug.org. IN PTR mail.lbcclug.org.

Thanks to the two Davids for helping me out with this. Amazing that I
have been doing sys admin work for 7-8 years but have never had to do DNS
hosting. Always another thing to learn, I guess.
