Nameserver software version issue
« on: 2013-02-18, 23:15:57 »
When I try DNS Report on http://www.dnsstuff.com, I get WARN about "Nameserver software version"
Quote from: "http://www.dnsstuff.com"
One or more nameservers responded to version queries. This can be considered a breach of security. If a malicious person or program had access to a version-specific exploit for your DNS server, displaying the version info openly will make their attack much easier. This should be removed or obscured. The nameservers that responded to version queries are:

xxx.xxx.xxx.xxx responded with "9.9.2-P1-RedHat-9.9.2-2.P1.el6"
(On official kloxo display "LxCenter-1.0" instead "9.9.2-P1-RedHat-9.9.2-2.P1.el6")

It's the same trick in my servers but this features not ready on current Kloxo-MR.

In next release, I want remove djbdns and change too powerdns. Other features are Kloxo-MR as secondary dns server dan options for recursive.

Powerdns more faster, less memory usage dan not need reload for add/delete/mod domains.

I mean have an option as 'As secondary dns' so it's make Kloxo-MR able as secondary dns for other servers (using Kloxo-MR or other panels).

Yes, maybe you can offer 'secondary dns' as free or payed service.

I do it but djbdns stopped on my services.

I try follow but do not affect:
Code: [Select]
# sh /script/fixweb
# service nginx restart
# reboot

If your problem is dns server (djbdns), restart web server will not impact.

Because djbdns issue, change to bind/named for dns server.

Sorry for djbdns. I will change this djbdns to powerdns. On your issue, change djbdns to bind/named via 'switch applications'

When I add below lines on named.conf according this instruction, It appears that recursive dns issue is solved but after server reboot bind stops!
Code: [Select]
options
{
  version "CHISPUM";
  allow-recursion {
127.0.0.1;
xxx.xxx.xxx.xxx
xxx.xxx.xxx.xxx
  };
};

What's about:
Code: [Select]
options
{
  version "CHISPUM";
  allow-recursion {
   127.0.0.1;
   xxx.xxx.xxx.xxx;
   xxx.xxx.xxx.xxx;
  };
};
