Re: no servers found
Jeremy, I did have "nameserver"and the IP in the resolv.conf file. I just found the trouble. I entered the wrong IP in the resolv.conf for my name servers. Now that I have corrected the IPs, everything seems to work OK. Thanks to everyone who replied. Thank you. Larry On Thu, Aug 21, 2014 at 11:48 AM, Jeremy C.

no servers found
HI, I am running BIND 9.6-ESV-R5-P1 on a Solaris 10 server. I can run queries without specifying a name server on my Solaris servers successfully. When I try to run a query on a Solaris 10 virtual server, I get "connection timed out; no servers could be reached" error. If I add the name servers from our main campus (or 8.8.8.8) to the virtual server's resolv.conf file, then dig will use the other name server and skip my name server to resolve the query which is successful. If i use dig and specify my master name server, then the query works fine. I do not understand why the virtual server cannot find the name servers on my campus (my building) unless I specify it.

Re: Performance tuning
Hi, My original post was about writing a report to optimize our DNS servers and the report needed to address two questions. Based on the answers I received, I will write our servers are already optimized and no further tuning is needed. Now about the two specific questions for the report. Q1 -- I don't believe the problem is DNS related. However, I have not been able to recreate the trouble so I don't know if there is any problem. As other list members have posted, they didn't have any problems with the pages rendering either. As far as asking me about the web sites staff, well, I am the technical contact for our web sites. Our Public Affairs department handles content related issues and I take of all server related things. I will double check the web server, but it shouldn't be using any rewrites for the main page. And I don't know who is complaining about the pages. This question came from my boss. Q2 -- The forwarders statement was added to our config file about six years ago. Some users complained they could not reach two or three specific web sites outside our domain. At that time, one of our network staff members told me his nslookup for the sites were timing out. I was instructed to insert the forwarder statement with the main campus servers acting as the forwarder. The time outs stopped and people stopped complaining. I don't know that adding the forwarder statement actually fixed any trouble but nslookups did not time out, people stopped complaining, and my boss was happy. (I know dig is better). Unfortunately, I don't remember which sites people were complaining about.

Re: Performance tuning
To the best of my knowledge, there are no problems with our DNS. We only host 25 domains. The report must also address these two specific questions: 1. Why does www.kentlaw.iit.edu load quicker than kentlaw.iit.edu in any browser? 2. What happens if we remove the forwarders option from named.conf? I can't duplicate the issue in Q1 and I'm trying to determine a way of testing Q2.

Performance tuning
Hi, I have been tasked with authoring a DNS report "to achieve optimal performance." The report must include: CPU usage memory usage bandwidth usage throughput latency I have found some information regarding the number of queries processed per minute but nothing of value for the above areas. Is there some documentation that discusses the above areas? We are running BIND 9.6-ESV-R5-P1, Solaris 10 on a SPARC server. My report will include the fact we must upgrade from BIND 9.6-ESV-R5-P1 Thank you in advance.

recursion and forwarding
Hi,
I am running one master server and one slave server with BIND 9.6.1-P3.
The global options section on both servers are identical.
In the options section I have,
allow-recursion { ck_domain; };
forwarders { 216.47.128.11; 216.47.128.12; 216.47.143.90; };
The ck_domain ACL contains internal IPs only.
The documentation I have read states that forwarders will forward a
client's query if the answer is not in the server's cache and the server
does not know the answer.
So when does recursion occur, before the query is forwarded or never? I
thought recursion was supposed to go looking for the answers. If
recursion does not return an answer then does the query get forwarded?
