#Is simple dns plus required for my server to work software
What now?Īfter some research I find out that Microsoft DNS server can’t do forwarding without recursion and that most people recommend using Bind (which I found to be un-friendly.) I did some more searching and found a DNS server software called Simple DNS Plus and the short version is, I love it! I installed it, shut down the Microsoft DNS service on one of my DNS servers, imported DNS records from one of the other servers and it was up and running. Why is this? Well, by disabling recursion you also disable forwarding and forwarding is needed for my clients DNS requests to get answered. However, now my clients on the inside are having problems getting to websites on the internet. Ok, great, now our DNS servers are not open servers and sure enough our internet connection is working much better.

Our DNS servers are Windows Server 2003 using the built in DNS software from Microsoft. Here’s what says about open dns servers “Open DNS servers increase the chances that of cache poisoning, can degrade performance of your DNS, and can cause your DNS servers to be used in an attack.” We’ve run our own DNS servers for several years that are both authoritative for our domain as well as answering dns requests for the clients on our network. What I found was we were getting a failure on the Open DNS servers section. Then for some reason I decided to run our domain through ’s excellent domain checking website. I searched and searched and couldn’t put a finger on what was causing the problem. In our sample we select to startup the dns server during system boot.For about a week our internet connection was coming to a crawl.

If you come back to the dns server configuration once more the following screen shots should match. If you configure your dns server the first time the yast screens could be a bit different. Starting the YaST configuration moduleĪs user root start the yast dns server configuration module: yast dns-server You need the packages bind and bind-chrootenv. The dns domain names (, ) in the following steps are example values used for documentation (see also RFC 2606, Section 3).

This local dns server will be configured to serve both areas (called zones in the bind language). This can be solved by a local running dns server.

But when a name server tells that it could not solve the request the dns client does not ask any further servers. While dns clients usual could try to connect multiple name servers in sequence, they only connect to the second or third name server, if the precursor one did not reply to the dns request.

You want to have access (name resolution) for the internet and also for an internal network, but neither the name server for the internet (providers name server) nor the internal one take care of the other area. Setup a local DNS server to have access to multiple DNS zones like internet and internal net Problem:
