[SOLVED] Force update of DNS records?

kikinovak · 10-28-2015, 08:38 AM

Hi,

I'm currently installing a website for a client. The system is running Slackware64 14.1 on a public root server. The client has bought the domain name "jouelacommewarren.com" at the french registrar OVH. Until now, DNS records have been managed by OVH's DNS servers.

First thing I did was to configure and activate BIND on the public root server, because I prefer managing DNS this way. Here's what /var/named/zone.jouelacommewarren.com looks like:

Code:

; /var/named/zone.jouelacommewarren.com
$TTL 86400
$ORIGIN jouelacommewarren.com.
@ IN SOA ns.jouelacommewarren.com. hostmaster.jouelacommewarren.com. (
   2015102801   ; sn
        10800   ; refresh (3 heures)
          600   ; retry (10 minutes)
      1814400   ; expiry (3 semaines)
        10800 ) ; minimum (3 heures)
        IN             NS      ns.jouelacommewarren.com.
        IN             NS      nssec.online.net.
        IN             MX      10 redirect.ovh.net.
jouelacommewarren.com. A       62.210.236.71
ns      IN             A       62.210.236.71
mail    IN             A       62.210.236.71
www     CNAME                  jouelacommewarren.com.
ftp     CNAME                  jouelacommewarren.com.

Here's a funny thing. When I connect to two different public servers that I manage, the new DNS records show up correctly on these two machines. Here's the first server:

Code:

[root@sd-48975:~] # hostname --fqdn
sd-48975.dedibox.fr
[root@sd-48975:~] # host jouelacommewarren.com
jouelacommewarren.com has address 62.210.236.71
jouelacommewarren.com mail is handled by 10 redirect.ovh.net.

Here's the second server:

Code:

[root@sd-41893:~] # hostname --fqdn
sd-41893.dedibox.fr
[root@sd-41893:~] # host jouelacommewarren.com
jouelacommewarren.com has address 62.210.236.71
jouelacommewarren.com mail is handled by 10 redirect.ovh.net.

But on the workstation on my local network, I still get the old record:

Code:

[kikinovak@alphamule:~] $ hostname --fqdn
alphamule.microlinux.lan
[kikinovak@alphamule:~] $ host jouelacommewarren.com
jouelacommewarren.com has address 213.186.33.5
jouelacommewarren.com mail is handled by 10 redirect.ovh.net.

Now I made sure to empty all local caches on the server, both Dnsmasq and Squid, but I still get the old DNS records. The local server is querying my ISP's DNS servers:

Code:

# /etc/dnsmasq.conf
domain-needed
bogus-priv
interface=eth1
dhcp-range=192.168.2.100,192.168.2.200,24h
local=/microlinux.lan/
domain=microlinux.lan
expand-hosts
no-resolv
# Nerim
server=195.5.209.150
server=194.79.128.150
...

Question to the DNS gurus: is there a way to force updating of the DNS records here? Or do I have to wait for a few hours or maybe days until this gets eventually done?

Cheers,

Niki

Problem solved automagically after a few hours.
