How to stop ANY zone transfer

2012-04-16 Thread Chiesa Stefano
Hello all. I'm developing a web application to apply massive dns changes automatically. I have a master dns server and three slaves. To test the application I'm going to create an identical copy of the master server (in the same network too). What is scaring me is the update of the slaves. If I don

Actually, this can be done. Create a zone file for "www.google.com", not "google.com". The zone file should like this (replace THIS_HOSTNAME with the name of your nameserver: @ IN SOA localhost root@localhost. ( 2012041

This is incorrect. It is illegal to have a cname and any other record on the same name in dns. The ns and soa count as records. On Apr 16, 2012 9:41 AM, "Matthew Huff" wrote: > Actually, this can be done. > > Create a zone file for "www.google.com", not "google.com". The zone file > should like

I had forgotten that about CNAME. But you can hard-code an A record to the nosslsearch.google.com record We have to use this technique (we point the A record to a proxy) for regulatory reasons to block IM connections except through our IM proxy. Matthew Huff | 1 Manhattanville R

Split DNS and zone transfers

2012-04-16 Thread Eric Chandler
I have a situation where I need to filter out our private infrastructure from our public-facing DNS servers. This is certainly something that should have been done a long time ago, but I just recently took over the spot. Now, I've seen plenty of examples using views and separate zonefiles, but w

You can also do it by IP in views but need separate IPs for each view. You can do that with virtual IPs on the same NICs as the primary IPs. Such virtual IPs of course have to be in the same subnet as the primary and also you’d need to insure firewall (including host level if any) is opened

Test DNSSEC validation

What is the best way to log DNSSEC failures in Bind without enforcing DNSSEC validation? That is I want to see what Bind would have rejected because of failed DNSSEC validation, but I do not want to return SERVFAIL to my client. -- Augie Schwer    -    au...@schwer.us    -    http://schwer.us _

Question about forwarders statements in 9.7

I was under the impression that bind would determine the best target forwarders to use, and send queries to those forwarders, but we had a situation over the weekend where one of the servers in the forwarder list was down, and bind continued to send queries to that forwarder even though it wasn't r
