Renumbering: resolver not working? still points to 212.x, instead of 85.y on >=1 machine

Hi all,
thanks for everyone's response to my wiki proposal. I hadn't intended a flame
war, and may respond selectively at a future date, when for instance, I am not faced with
a puzzle, as follows.
dig returns the correct value 85.y on my VPS.
dig returns the old address 212.x elsewhere (at work).
Should I be concerned? I must access the ethernet address to my VPS--not the name--from
'elsewhere'. I changed bind at least 24h ago. Is the 'expire' time* of 7
days (current setting) responsible for this, or is my problem more insidious?
*the third entry after the 'serial number' in a bind config
Thanks for any/all replies.
Cheers,
Max

When querying what host name?

That isn't what "expire" controls; TTL controls this. It may be the
TTL or it may be something else.
*the third entry after the 'serial number' in
a bind config
The TTL appears as the first line in a BIND-compatible zone file:
http://www.zytrax.com/books/dns/apa/ttl.html
You can also override TTL on a per-record basis. Records without an
explicit TTL use the value as above. But as I say it may not be
that. We can check once we know what host name you are querying.
Cheers,
Andy

Two things you can look at: dig tells you the TTL remaining on any
entry when you query it. For example:
hrm@ruthven:~ $ dig oxfordflutes.co.uk
; <<>> DiG 9.7.3 <<>> oxfordflutes.co.uk
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 52296
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;; QUESTION SECTION:
;oxfordflutes.co.uk. IN A
;; ANSWER SECTION:
oxfordflutes.co.uk. 86397 IN A 85.119.82.48
;; Query time: 0 msec
;; SERVER: 10.0.0.10#53(10.0.0.10)
;; WHEN: Tue Feb 7 21:50:55 2012
;; MSG SIZE rcvd: 52
The "86397" in the ANSWER SECTION is the TTL, and shows that I've
got a few seconds short of 24 hours left for this entry in the cache.
This value will count down to zero, at which point the cache expires
and a new authoritative entry (hopefully the right one) will be
retrieved.
The other thing is to use "@servername" in your dig query, which
will explicitly bypass the locally configured resolvers, and query the
named DNS server.
hrm@ruthven:~ $ dig @ns1.bb-online.net. oxfordflutes.co.uk
[...]
In this case, I'm querying one of the definitive servers for
oxfordflutes.net, and so should get the results that I've asked them
to publish. You can check whether the DNS servers under your control
(usually the primary and one or more secondaries) are sending the
right answers. If they are, then you should simply have to wait until
the TTL in the previous query reaches zero. If not, then you have some
kind of misconfiguration of your servers.
Oh, and you should be able to get the definitive list of
nameservers by issuing an NS query:
hrm@ruthven:~ $ dig NS oxfordflutes.co.uk
; <<>> DiG 9.7.3 <<>> NS oxfordflutes.co.uk
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 43912

;; ANSWER SECTION:
oxfordflutes.co.uk. 86400 IN NS brain.bb-online.co.uk.
oxfordflutes.co.uk. 86400 IN NS ns1.bb-online.net.
oxfordflutes.co.uk. 86400 IN NS ns2.bb-online.net.

;; SERVER: 10.0.0.10#53(10.0.0.10)
;; WHEN: Tue Feb 7 21:54:55 2012
;; MSG SIZE rcvd: 115
So here my definitive nameservers are brain, ns1 and
ns2.bb-online.net. Check the data returned by all of the servers
(with the @server syntax above) for the NS query, just to see if one
is out of sync with the others.

Hi,
For your domain I get:

This looks like an old IP. Have you updated your DNS at zen?
I have done so earlier, I'd forgotten that Andy had mentioned this need
in one of his very early emails about re-numbering but found it when I
looked.
It is just going to take time for the change to propagate. One odd
thing is that I can now access the databases from my linux system but
my wife cannot as yet from her WinXP system despite both of us being on
the same local network here at home.
At the moment she is more concerned that the URL for her database is
all over facebook and can be found by googling when she was hoping it
wouldn't get spread worldwide. Trying to explain to her that nothing
can be kept secret for long on the WWW isn't easy. But at least that
has taken her mind of the fact she cannot access her database to edit
it.

That'll be due to local caching by the OS. To clear it on WinXP open up a
command prompt and run ipconfig /flushdns
You may also wish to close/restart whatever app she is using to access the
database in case it is also caching the old result.

Thanks for that tip. I've never been a widows user so had no idea that
command existed.

Geneweb databases are accessed via a web browser URL, so cleared the
cache and history in Opera
That seems to have done the trick and have just been able to access
her database.
Many thanks

That's because the DNS record for that domain (startx.co.uk) still uses

You need to change the IP at which the A record startx.co.uk points. It
looks like this is hosted with Zen:
% host -t NS startx.co.uk
startx.co.uk name server ns0.zen.co.uk.
startx.co.uk name server ns1.zen.co.uk.
Try there.

It's now live on the Zen DNS servers.
So a maximum of 24 hours, with any luck.
Any *new* [1] visitors will get the new IP. E.g. from our VPS
'dig' returns the new IP.

Yes, because it's pointing at the wrong IP address right now.
I can ssh johnlewis(a)85.119.82.129

/etc/resolvconf has

nameserver 85.119.80.232
which are the Bitfolk DNS addresses I think
If you do:
$ dig @ns0.zen.co.uk startx.co.uk.
$ dig @ns1.zen.co.uk startx.co.uk.
then you will see that you're still publishing 212.13.194.129 as the
IP address for your domain from your autoritative servers
(ns0.zen.co.uk and ns1.zen.co.uk). You need to fix this -- probably
via some kind of control panel app at Zen. Approximately 24 hours
after you fix the records at Zen, everyone should have got the right
records again.

John,
Essentially, your domain names mapping to the right IP address are being controlled by
zen, not bitfolk.
You must login to your zen control panel, and change all the old IP address mappings to
the new IP.

I can ssh johnlewis(a)85.119.82.129

so could reboot if need be.
I can access my websites by using IP addresses rather than domain names
and have advised my regular users to do so for now but "casual"

Can I assume that the domain names will get resolved in a few hours or
thereabouts or do I need to do something else to get this working.

nameserver 85.119.80.232
which are the Bitfolk DNS addresses I think

New subject: Renumbering: resolver not working? still points to 212.x, instead of 85.y on >=1 machine
I have just checked, using nslookup, through the google public DNS
(8.8.8.8) Your new IP is now showing. However, when I go through BT
nameservers, it's still the old one. It's gradually filtering through

John,
Essentially, your domain names mapping to the right IP address are being
controlled by zen, not bitfolk.
You must login to your zen control panel, and change all the old IP
address mappings to the new IP.

Thanks to all who replied. I decided to wait out the 48hrs left on the local nameserver
(Hugo's tip) and then the problem sorted itself. :)
Valuable tips might like these ought to be compiled into a sysadmin pocketbook:
'wisdom from bitfolk'.
Cheers!

dig returns the correct value 85.y on my VPS.
dig returns the old address 212.x elsewhere (at work).
Two things you can look at: dig tells you the TTL remaining on any
entry when you query it. For example:
hrm@ruthven:~ $ dig oxfordflutes.co.uk
; <<>> DiG 9.7.3 <<>> oxfordflutes.co.uk

oxfordflutes.co.uk. 86397 IN A 85.119.82.48

The "86397" in the ANSWER SECTION is the TTL, and shows that I've
got a few seconds short of 24 hours left for this entry in the cache.
This value will count down to zero, at which point the cache expires
and a new authoritative entry (hopefully the right one) will be
retrieved.
The other thing is to use "@servername" in your dig query, which
will explicitly bypass the locally configured resolvers, and query the
named DNS server.
hrm@ruthven:~ $ dig @ns1.bb-online.net. oxfordflutes.co.uk
[...]
In this case, I'm querying one of the definitive servers for
oxfordflutes.net, and so should get the results that I've asked them
to publish. You can check whether the DNS servers under your control
(usually the primary and one or more secondaries) are sending the
right answers. If they are, then you should simply have to wait until
the TTL in the previous query reaches zero. If not, then you have some
kind of misconfiguration of your servers.
Oh, and you should be able to get the definitive list of
nameservers by issuing an NS query:
hrm@ruthven:~ $ dig NS oxfordflutes.co.uk
; <<>> DiG 9.7.3 <<>> NS oxfordflutes.co.uk
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 43912

;; QUESTION SECTION:
;oxfordflutes.co.uk. IN NS
;; ANSWER SECTION:
oxfordflutes.co.uk. 86400 IN NS brain.bb-online.co.uk.
oxfordflutes.co.uk. 86400 IN NS ns1.bb-online.net.
oxfordflutes.co.uk. 86400 IN NS ns2.bb-online.net.
;; Query time: 48 msec

;; WHEN: Tue Feb 7 21:54:55 2012
;; MSG SIZE rcvd: 115
So here my definitive nameservers are brain, ns1 and
ns2.bb-online.net. Check the data returned by all of the servers
(with the @server syntax above) for the NS query, just to see if one
is out of sync with the others.
Hugo.
