Hello, I am trying to configure a single CentOS 5 machine as a server
for two unrelated websites:
example.eu
example.de
The server has four IP addresses assigned to it:
1.1.1.136
1.1.1.171
1.1.1.172
1.1.1.188
I plan on hosting example.eu on this server with these two IP
addresses for its name servers:
1.1.1.136 - ns1.example.eu
1.1.1.188 - ns2.example.eu
Likewise, I plan on hosting example.de on this server with these two
IP addresses for its name servers:
1.1.1.171 - ns1.example.de
1.1.1.172 - ns2.example.de
These are my relevant configuration files:
[r...@centos-55-32-minimal ~]# cat /etc/named.conf
options {
directory "/etc";
pid-file "/var/run/named/named.pid";
listen-on {
any;
};
};
zone "." {
type hint;
file "/etc/db.cache";
};
zone "example.de" {
type master;
file "/var/named/example.de.hosts";
};
zone "example.eu" {
type master;
file "/var/named/example.eu.hosts";
};
[r...@centos-55-32-minimal ~]# cat /var/named/example.eu.hosts
$ORIGIN example.eu.
$TTL 86400
example.eu. IN SOA ns1.example.eu. ns2.example.eu. (
5; Serial - increment me
10800
3600
604800
38400 )
IN NS ns1.example.eu.
IN NS ns2.example.eu.
IN A 1.1.1.136
IN A 1.1.1.188
www IN A 1.1.1.136
www IN A 1.1.1.188
ns1 IN A 1.1.1.136
ns2 IN A 1.1.1.188
[r...@centos-55-32-minimal ~]# cat /var/named/example.de.hosts
$ORIGIN example.de.
$TTL 86400
example.de. IN SOA ns1.example.de. ns2.example.de. (
5; Serial - increment me
10800
3600
604800
38400 )
IN NS ns1.example.de.
IN NS ns2.example.de.
IN A 1.1.1.171
IN A 1.1.1.172
www IN A 1.1.1.171
www IN A 1.1.1.172
ns1 IN A 1.1.1.171
ns2 IN A 1.1.1.172
In BIND and in the registrar control panel for example.eu I had set
the IP addresses originally to 1.1.1.171 and to 1.1.1.172, however due
to a technical problem with the .de domain I later changed the
configuration to 1.1.1.136 and 1.1.1.188 (because it turns out that
.de domains cannot have the two nameservers on the same C block, and
only the 171 and 172 addresses I can swap for another address).
However, even though the registrar control panel is set to
ns1.example.eu as 1.1.1.136 and ns2.example.eu as 1.1.1.188, I still
see this in whois:
[r...@centos-55-32-minimal ~]# whois example.eu
// snip irrelevant lines
Nameservers:
ns1.example.eu (1.1.1.171)
ns2.example.eu (1.1.1.172)
I last made changes to the BIND configuration and to the registrar
control panel on Friday, 2010-9-24 which was three days ago. Therefore
I do not suspect that DNS propagation time is the issue here. Of
course, I also increased the serial line in the zone files when those
files changed. What am I missing, or what might I have done wrong?
Thank you in advance.
