Where is My DNS Service Originating

We have an OS X.4.8 Server that is configured to be a DNS forwarder. 15-20 machines are using it for DNS even as I write this.
Today, a network issue arose and while I was investigating I noticed that the "forward" entry in the servers's /etc/named.conf was gone!
Since the computers using this machine are not having any DNS issues, I assumed that Server must be pulling the "real" DNS server addresses that would ordinarily be in the Forward section of Named.conf from the servers Network control panel.
I went to the Network Control panel and found that the the DNS entry is set to: 127.0.0.1.
So to what servers are DNS requests being sent? Especially if there are no entries in Named.conf AND nothing in the DNS section of the unit's Network control panel?
Thanks,

It is possible I suppose that DNS was not restarted when the config file was changed so is still operating under the previous config.
I have a hunch you're right: the named.conf file got munged somehow (Server Admin bug -- this is ringing a bell with me) and we just haven't been slapped by it since DNS hasn't been restarted recently. The server itself has been up 111+ days.
If true, then all I can say is: "Wow, that was close."

It looks like your database is using automatic service registration (most do these days) in which case entries in the listener.ora aren't generally needed.

Windows Server 2008 R2 DNS service issue with BitLocker

I recently installed BitLocker on a Windows Server 2008 Platform. I did not encrypt the boot partition because the server hardware BIOS did not have the necessary requirements to encrypt the system drive.
The Server roles are ADSM, DC and File Server. For DC operation I am also running the DNS service.
When I installed the DNS role I was prompted to install the Log files on a different volume than the OS. I did this, but unfortunately, it was the same volume that was encrypted.
Since I could not encrypt the system disk, the encrypted volume must be unlocked via password in order to mount. Here in lise my problem.
When I do a full reboot of the server, I get to the point in the boot process where my mouse is visible and operational (this would be just before the Windows OS logo displays, I believe), then the server reboots. On the next boot up I am given the diagonstics
and recovery dialog because the OS failed to boot.
I believe the failure is the DNS service trying to launch, but because the log files are on the encrypted drive and it has not been unlocked, the system sees this as a security problem and reboots
Does this make sense? If it does, is there a way to boot 2008 R2 with the DNS service disabled, say with the original install disk in recovery mode?
Any help would be greatly appreciated as this system cannot be booted in its current state.

Hi,
I believe you mean the Active Directory Logs not the DNS logs, because these are necessary to startup a domain controller, because the AD database depends on these logs.
So if you have AD logs on a different partition and that is encrypted with Bitlocker you could probably automatically unlock it.
So you did not encrypt OS partition because the server does not have a TPM fully compliant chip ?
manage-bde /?
manage-bde -autounlock -enable Driveletter:
But you have to be able to boot server normal mode I am not sure if the command can be used in DSRM mode.

Lion Server DNS service not working for locally created zones. Caching working fine.

OS Lion Server DNS service not working for local zones. Was fine under Snow leopard server but Lion server upgrade has severely broken my DNS and web sites. Zones look fine under Server Admin but keep getting "query failed (SERVFAIL) for xxxx at /SourceCache/bind9/bind9-42/bind9/bin/named/query.c:3921" in the logs. BTW - Server Admin cant seem to see the log file either.
Surely someone actually tested that DNS still worked on Lion?

I upgraded from Snow Leopard Server to Lion Server on day 01. I hit the same issue where, after the upgrade, my Lion Server stopped serving names for my private local domain.
I finally took a few minutes to figure out what was wrong. After turning on debug logging and looking through the logs, I found my particular issue, now resolved.
The issue I had was, when the domain initially was setup when I installed Snow Leopard Server, for some reason it created a zone just for the server (in my case, something like zone "s-01.mydomain.priv"), and a separate zone for all the other machines (zone "mydomain.priv", containing all the private IPs for my local domain). I never messed with it because it worked, but generally I would have put all of them in the same zone.
My zone "mydomain.priv" had a nameserver and mail exchanger entry for my server, s-01.mydomain.priv. I could see this in the Server Admin app on the DNS bubble, Zones tab, mydomain.priv selected, and the General Info panel. This was fine in Snow Leopard. This was failing the zone load in the updated bind for Lion Server, though. The issue was that the "mydomain.priv" zone was referencing the s-01.mydomain.priv server, which was not defined in the "mydomain.priv" zone but rather in the "s-01.mydomain.priv" zone.
My fix:
1. In Server Admin, add the server to the zone "mydomain.priv". I put an A record (Add Machine) in the "mydomain.priv" zone for my server named s-01.mydomain.priv.
2. shut down DNS on the OS X Lion Server (hit the Stop DNS button on Server Admin).
3. edit /etc/named.conf by hand, removing the specialized zones that contianed just the server. In this case, it would be the section titled 'zone "s-01.mydomain.priv"' and the section titled 'zone "3.10.1.10.in-addr.arpa"'. Your in-addr.arpa zone name will change based on whatever your server IP address was. My internal one happened to have s-01.mydomain.priv mapped to 10.1.10.3.
4. Once the specialized zones for just the server were removed, I started the DNS up again. Instead of serving four zones as it had in OS X Snow Leopard Server, it now servers two zones. And, now, it is resolving my local machines for the mydomain.priv zone.
YMMV. I did note that it wasn't totally necessary to do step 3, but I never really understood the need for the specialized domain, and keeping it around would have a copy of data that would just confuse things.
Hope that helps. That's been the only hiccup I've noticed updating to OS X Lion Server thus far.

Servermgrd: Where to specify DNS for server?

Been having a lot of trouble with Mac OS X Server 10.4.11 (running on PowerMac G5, 2 GHz, 2.5 Gb of RAM) the last few days. Some recurring log items I see are:
Jun 26 07:40:55 GBG-Server servermgrd: servermgr_dns: no name available via DNS for 172.16.1.64
Jun 26 07:40:55 GBG-Server servermgrd: servermgr_dns: no reverse DNS entry for server, various services may not function properly
I am not using the DNS service within OS X Server, it's a standalone that hosts a few databases and afp:// file sharing. Where does a person specify the "DNS" referred to in the log entries above??

Hi
Leif is absolutely correct in what he says, however if all you want the Server to do is host AFP and/or SMB shares you don't need internal DNS services. Admittedly things do work better with them but if you can ignore the warnings in the log it should not affect anything.
If the Server is supposed to be or may want to be an OD Master then you really must address the problem otherwise you don't really have an LDAP Server and it will cause you problems.
If you are not having any problems and things are working as they should be, ignore the logs and leave things as they are. Think of it a bit like going out on a sunny day and being warned by everyone you meet that it may rain later on and to take an umbrella with you. Not a great analogy I know but you get the point?

Is a Dynamic DNS Service included in my FiOS Bundle?

I have the FiOS TV, Phone & Internet Bundle (internet upgraded for $5 extra for faster speeds) and switched from Cable.
I know that Cable provided all of their Boost internet premium speed customers with a bundle of goodies, including a Dynamic DNS service.
Does Verizon offer Dynamic DNS service included as well?
If not, which is easiest to use (I have a Mac running OS X 10.5.7)
I noticed that my FiOS Router Firmware has Dynamic DNS section, but it's very unclear as to if it is meant for a Verizon specific service or a third party service.
Please advise; thanks!

That screen you captured is where you would enter your dyndns.org account info and thereby get dynamic dns running on your setup.
It's not really accurate to say the service is 'included' in the bundle, it's just that the router is capable of talking with this 3rd party service - most routers can do so nowadays.

Providing DNS Service

Hello,
I am come across some RFPs for Internet service where one of the requirements is for the ISP to provide DNS service to the customer. Is this something as simple as giving them the IP address of a DNS server to use or could it be something more?
Thanks in advance. All replies rated.

Hi,
If you see the concepts of DNS in internet is when ever you want to host your web server in internet and you dont have authorative dns server with you then we ask some of the ISP's to become a authorative DNS server for your web server which is exposed to internet.so when ever a request comes for your web site the authorative DNS server's ISP will resolve and provide the ip address of your web server to users.
and if you have DNS server at you own datacenter then we ask the root DNS server in internet to redirect the traffic for your web site to your own DNS server so that it can resolve the page and provide the ip address.
Hope to Help !!

Where can I get an original x58 Pro-E IOH chipset heatsink assy?

Recently built an i7 gaming rig and like everyone else had high nb temps which I'm not very keen on.
I had a Thermalright HR-05 from another build (took it out of my old system and replaced it with the original HS and sold that PC leaving me with it) that I'll use on the nb, but covering the sb will be difficult since I'm running 2 4870 cards in the pci-e slots, covering the sb and not being able to move the cards to free space above it. I don't really want to get something too fancy for the sb (the sli version of the nb cooler) as it doesn't seem to get hot.
I was thinking along the lines of using the HR-05 for the nb, cutting up the heat-pipe of the original chip-set HS and just using it on the sb as temps and clearance will be fine. Problem of course is if ever need to rma the board, I'm screwed. I've read all the posts about issues with the hot IOH temps and solutions, and this is the way I'll think I'll go.
Currently my temps are up around 90 on load, and that's in winter! It's around 10 C in my room right now and when summer comes around with 30 C that's gonna shoot up!
Long story short, does anybody know where I can get an original X58 Pro-E IOH heatsink assy that I can keep safe in case I need it (touch wood)

I have thought about that, saw it under some suggestions to fix high temps. But they have that shoved toward the NB. My HR-05 will take care of the NB (plus some serious OC in sumemr which i want to do) I just need a HS for the southbridge , and it seems that the only HS that has enough clearance and fits into the MB with long cards in xfire or sli is the original SB HS, which leaves me wanting to cut the orginal HS up to reuse on the SB and finding another complete HS just in case.

How to resolve a host name from IP using JNDI/DNS service provider

Hi
I got two questions on JNDI/DNS service provider:
1) How to resolve a host name when i got an IP
I understand How I do it inverse.
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.dns.DnsContextFactory");
env.put(Context.PROVIDER_URL, "dns://"+server+"/"+domain);
DirContext ictx = new InitialDirContext(env);
Attributes attrs1 = ictx.getAttributes(host, new String[] {"A"});
2) This example above works when I specify the domain in the provider url.
If I am not specifing a domain but only the dns server I got an NameNotFoundException.
What should I do if I don't got the domain?
get the availible domains and loop on them?

Hi,
if your DNS server supports that, you can do a reverse DNS lookup. This works as follows:
String server = "your.dns.server";
String domain = "in-addr.arpa";
String ip = "4.3.2.1";
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.dns.DnsContextFactory");
env.put(Context.PROVIDER_URL, "dns://" + server + "/" + domain);
DirContext ictx = new InitialDirContext(env);
Attributes attrs1 = ictx.getAttributes(ip, new String[] {"PTR"});1: Use the pseudo-domain in-addr.arpa
2: Use the reverse IP address for lookup, i.e. if your host has 1.2.3.4, use 4.3.2.1!!
3: Request the PTR attribute

Non-ISP DDNS with Apple DHCP and DNS Services

I have two questions about Dynamic DNS (DDNS) as it applies to Apple's DNS and DHCP services within my home network. I am not talking about DDNS in the context of making my external-facing router available by a domain name on the Internet using the dynamically-assigned IP from my ISP.
Starting with Snow Leopard Server, I attempted to use Apple's DNS and DHCP services (I have the firmware-based DHCP service in my router turned off.) The difficulty I immediately faced was that Apple's DHCP implementation didn't update the DNS service as IPs were handed out to DHCP clients. Because of this, it wasn't possible to access hosts by their hostname, since getting a DHCP-assigned dynamic IP at boot-up didn't do anything to automagically register the hostname-to-IP mapping in DNS. Manually registering the hostname in DNS was pointless, becuase over time the client IP address can and did change. I could create static IP assignments based on the MAC address, but doing that for all of the devices on my home network sort of defeated the purpose of using dynamic IPs.
The only solution I eventually found was to go out and get an open source DHCP server, compile it for my Mac, install it, and configure it. After doing this, everything worked great; every time a new host or other device was booted it got a dynamic IP through DHCP, and then the DHCP server automatically updated Apple's DNS serive with the hostname and assigned IP. I could immediately access every device on my network by hostname. As IP addresses changed over time, the hostname-to-IP mapping in DNS was automatically updated.
Except, Apple's point upgrades kept breaking my non-Apple DHCP install. Every time I applied software updates to my server I had to go back and re-finagle DHCP to get it to automatically start and run. By the time Lion Server came out, I drank the Kool-Aid and went back to Apple's DHCP implementation. I was disappointed that it still didn't seem able to update DNS with hostnames as it assigned IPs, but I was so tired of mucking about at the command prompt to fix DHCP every time Software Updates broke it, I just lived with the inconvenience of not being able to access devices on my network by hostname.
I'm sorry to say this, but Windows Server has had this capability since at least server 2003. In fact, until I dumped my Windows Server and switched to Snow Leopard Server, I was running Microsoft's DNS and DHCP services on Server 2003 and they did exactly what I'm describing brilliantly.
Can anyone offer any advice here? Does Mountain Lion's implementation of DHCP allow for DDNS updates to the DNS service? If not, how are other people handling this? Should I go back to running Windows Server for my DNS and DHCP services? My Netgear WNDR3700 router appears to have the standard, substandard DHCP server in firmware as most home routers, and no facility for DNS at all--much less the ability to update an on-site DNS sever with IP addresess it hands out. In fact, the only appliance I know of that does this is the InfoBlox my employer uses, but that's too expensive for a home solution.
As a Post Script, I'll add that I've been VERY unhappy that I lost the ability to bind Windows clients to Open Directory under Lion Server. Since I'm starting to see articles that say this capability hasn't been added back to Mountain Lion Server, I'm seriously considering implementing a Windows Server AD master and establishing a "magic triangle" or "golden triangle". If I end up having to do that, I wonder if I might as well just go back to using Microsoft's DNS and DHCP services.

Hi,
Whether to move your DHCP to another server depends on the workload of your server. If there are too many clients on the network, you should move your DHCP to another server.
Did the record which owned by the machine generate before you configure the DnsUpdateProxy group? You can try to regenerate the record and check the result.
For more detailed information, you can view the link below.

How do I install OS 10.7 NOT 10.7.5 on a mac running Snow Leopard 6.8 i.e. where can I find the original install app for Lion OS 10.7.0?

I'm running 10.6.8 Snow Leopard fine on my MacPro1,1, Dual-Core Intel Xeon, 2.66 GHz Mac, but I need to install Lion 10.7.0 to run a program I need.How do I install OS 10.7 NOT 10.7.5, because I get this message when I try to install 10.7.5, which I've downloaded:"This update requires Mac OS X version 10.7." on a mac running Snow Leopard 10.6.8, So i need to install the original 10.7.0 over the 10.6.8 i.e. where can I find the original install app for Lion OS 10.7.0? The original Lion 10.7. is not avaialable for purchase from the App store or anywhere, even C-Net . Where can I find it to purchase?
Also it seems I cannot install Mountain Lion over 10.6.8 as advertised. When I go to purchase I get this message: "We could not complete your purchase. OS X Mountain Lion is not compatible with this computer." I think my computer can handle it (specs above) Are there any workarounds to this?

If you're getting a "This update requires Mac OS X version 10.7" message, than you have the updater and not the full installer. Go to your Purchases section of the Mac App Store and you should see the full version there. But it may be 10.7.5, though in my system is shows as being from 2011 which would appear to be the original version.
As to Mountain Lion, that's supported only on the Early 2008 Mac Pro or newer.

Java Web Start and DNS Service Provider

I have an implementation of a DNS Service Provider that works fine as an Application. But when deployed as an applet or application through Java Web Start, it is not picking up the DNS provider override
It is like this. I have a Simple Test Program
dabba#cat Test.java
import java.net.*;
import sun.net.spi.nameservice.NameService;
import sun.net.spi.nameservice.dns.DNSNameService;
public class Test {
public static void main(String args[]) throws Exception{
try {
System.setProperty("sun.net.spi.nameservice.provider.1", "dns,mine");
InetAddress ia = InetAddress.getByName(args[0]);
System.out.println(ia);
catch(Exception e) {
System.out.println("in exception handler" + e);
dabba# cat MyNameService.java
import sun.net.spi.nameservice.NameService;
import sun.net.spi.nameservice.dns.DNSNameService;
import java.net.UnknownHostException;
public class MyNameService implements NameService {
static {
//System.setProperty("sun.net.spi.nameservice.nameservers", "localhost"); // ETL
NameService ns;
public MyNameService() throws Exception {
ns = new DNSNameService();
public byte[][] lookupAllHostAddr(String host) throws UnknownHostException {
System.out.println("*** lookup host = " + host);
byte[][] a = new byte[1][4];
a[0][0]=(byte)127;
a[0][1]=0;
a[0][2]=0;
a[0][3]=(byte)1;
System.out.println("return a.length = " + a.length);
return a;
public String getHostByAddr(byte[] addr) throws UnknownHostException {
throw new Error("not implemented");
dabba#cat MyNameServiceDescriptor.java
import sun.net.spi.nameservice.*;
public final class MyNameServiceDescriptor implements NameServiceDescriptor {
public NameService createNameService() throws Exception {
return new MyNameService();
public String getProviderName() {
return "mine";
public String getType() {
return "dns";
dabba#cat META-INF/services/sun.net.spi.nameservice.NameServiceDescriptor
# dns service provider descriptor
MyNameServiceDescriptor
dabba# java -cp . Test www.sun.com
*** lookup host = www.sun.com
return a.length = 1
www.sun.com/127.0.0.1
So the above program works as intended as an application. Whatever hostname I specify, it returns localhost. Now, I'm not able to get this to work when I embed this in an Applet or Application launced through Java Web Start. Am I missing something
thanks,
Balaji

We are trying to do the same thing for a different purpose. You need to set the override sooner than WebStart lets you... It has to be on the command line.
We are trying to overide the default nameservice because it uses reverse dns which is slow at some of our sites. We need to set the parameter
sun.net.spi.nameservice.provider.1=dns,sun before the VM starts using webstart. The only way we can do this is by setting the environment variable
JAVAWS_VM_ARGS=-Dsun.net.spi.nameservice.provider.1=dns,sun on the client. This is not real easy from the server side.
Is there any way we can make the client default to this nameservice provider? There must be some file somewhere on the client I can put this property in...

What is DNS Services and why does it use so much data?

I have 300MB to use a month on my iPhone 4S (most recent iOS) and I'm normally pretty good with it because I'm connected to WiFi a lot. All of a sudden, my data usage spikes and my DNS services usage has gone up to 40MB. What is this and how do I keep it from spiking like this? It's incredibly annoying.
Also, any other tips on saving data while connected with the 3G? As mentioned before, I only have 300MB so I like to stretch it for the month.

DNS (Domain Name Service) is the Internet "address book" of web sites. Whenever you go to a site such as http://apple.com your browser must make calls to the DNS server specified in your Network Settings to translate "apple.com" into Apple's IP (Internet Protocol) address of 17.178.96.59. Any time you access any Internet resource (such as sending or receiving email, playing multi-player games, using a browser, Using any app that accesses data on the Internet such as news, weather, stocks, etc) one or more DNS lookups must be made. Many web sites have content from several different sites. Each site referenced on the page must also be looked up. Each query is small (~100 bytes), but they can add up.
