Ok, many folks have been extremely helpful. I appreciate every bit of
help, but yet things just aren't quite straight.
I am wondering if there's just something else I am missing here.
I am happy to rtfm, but after doing this and with the help, I am either
still quite confused or there's yet something issing.
I'll post all the relavent info and see if someone could still find a
problem I'm missing.
This is the most frustrating step in my education thus far and I'm loosing
what little hair I have.<G>
tnx to all.
First here is my hosts file.
First let me state that currently my n3byy domain is being done through
yi.org, but I've registered lrxms.net, it has been pointed to ns.lrxms.net
and I'll have my ISP Speakeasy do secondary.
I mention this because I don't know if the yi.org domain is part of the
problem at all so I mention it.
#
# hosts This file describes a number of hostname-to-address

zone "." {
type hint;

};
zone "0.0.127.in-addr.arpa" {

file "pz/local";
};

};
zone "20.254.216.in-addr.arpa" {
notify no;
type master;
file "pz/216.254.20.117";
};
Here is the lrxms file located in /var/named/pz:
;zone for lrxms.net
;
@ IN SOA ns.lrxms.net. hostmaster.lrxms.net. (
2000092401 ; Serial

2H ; Retry 2 hour
1W ; Expire after 1 week
1D ) ; Minimum TTL of 1 day
IN NS ns.lrxms.net.
;
localhost. IN A 127.0.0.1
ns IN A 216.254.20.117
n3byy.lrxms.net. IN A 216.254.20.117
mail IN a 216.254.20.117
pop IN A 216.254.20.117
ftp IN A 216.254.20.117
www IN A 216.254.20.117
;
; aliases
;
;wh.lrxms.net. IN CNAME lrxms.net.
;wh216.lrxms.net. IN A lrxms.net.
;
lrxms.net. IN MX 10 lrxms.net.
lrxms.net. IN MX 20 lrxms.net.
Now the local file:
; local file for lrxms.net
;
@ SOA localhost. hostmaster.localhost. (
2000092401 ; serial,today's date + today's serial
8H ;;refresh 8 hours
2H ; retry 2 hour
1W ; expire 1 week
1D ) ;minimum TTL 1 day
;
IN NS ns.lrxms.net. ; init address of name server
1 IN PTR localhost.
Lastly, the 216.254.20..117 file:
; db file for 216.254.20.117
;
@ IN SOA ns.lrxms.net. hostmaster.lrxms.net. (
2000092401 ; serial,today's date + today's serial
8H ; refresh 8 hours
2H ; retry 2 hour
1W ; expire 1 week
1D ) ;minimum TTL 1 day
;
IN NS ns.lrxms.net. ;name server
117 IN PTR n3byy.lrxms.net.
Here is my resolve.conf file
search ns.lrxms.net
search speakeasy.org
nameserver 127.0.0.1
nameserver 216.254.20.117
nameserver 216.231.41.22
nameserver 216.231.41.2
Now here is what happens if I comment out references to speakeasy and run
nslookup and look for localhost for starters and then speakeasy.net
*** localhost can't find localhost: Server failed
> speakeasy.net
Server: localhost
Address: 127.0.0.1
*** localhost can't find speakeasy.net: Non-existent host/domain

Here is the named_dump.db file:

I see several errors, but I am seriously confused as to why. I setup the
files as I thought they were suposed to be and according to the info I got
here. Its likely I've misunderstood something. I will get this figured out
yet of course with help.
Geez and I thought this was going to be fairly easy.
I've been reading the Oreilly and Associates book which is quite good, but
man I sure missed something along the way I think.
I thought I had a handle on dns, but this sure proves I don't.
