[cobalt-users] Cube3 DNS problem

["Steve Groom" <steve.groom@xxxxxxxxxx>]

Hello,
I have been struggling with DNS problems for the past few weeks. I have a
Qube3 (dns1.mep.ch) and a Qube2 (dns2.mep.ch).

Most of the config seems to be working, we receive e-mails and can serve
pages to the internet. I am working through DNS & BIND from O'Reilly but it
does not seem to help my little problem. (btw this book doesn't seem to
address the issues of virtual hosts)

I can ping www.mep.ch and mail.mep.ch but I cannot ping mep.ch

Some information:

dns1.mep.ch/etc/named/db.mep.ch
; db.mep.ch
;
; This file was automatically generated by dns_generate.pl.  Do not
; edit this file directly.  If you need to make additions to this
; file that CCE does not support, add your extra records to the
; db.mep.ch.include file.

        3600 ; retry
        604800 ; expire
        86400 ; ttl
        )

The RaQ4 chraq001 hosts steve.mep.ch and www.mep.ch The mail server is not a
Cobalt device.

These were created in the Qube3 GUI as this:

chraq001 . mep.ch              A     194.148.6.210
194.148.6.210/255.255.255.0    PTR   chraq001 . mep.ch

I checked it on IPPlus and it returns no errors / warnings:

No errors found in "mep.ch"
No warnings found in "mep.ch"

But it still does not work :(

from dns1 telnet:

[root named]# nslookup - dns1.mep.ch
Default Server:  dns1.mep.ch
Address:  194.148.6.242

> mep.ch
Server:  dns1.mep.ch
Address:  194.148.6.242

*** dns1.mep.ch can't find mep.ch: Non-existent host/domain

This results in two real problems:
  internally dns1 cannot send e-mail to cobalt@xxxxxx
  and externally if I try to open web page mep.ch I get host not found and
not www.mep.ch

Sorry for a long mail, I'm trying not to forget anything.

best regards
