DynaDNS Bonjour and DNS Service Discovery

Ok I have been useing the Time Capsule from the time it came out I am exspanding my home network and am trying to do it as layed out in this link
http://dyn.com/support/airport-time-capsule-with-dynamic-dns/ and http://dyn.com/support/bonjour-and-dns-discovery/ but I can not find the settings shown in the screen shots I have firmware 7.6.1 and airport utility 6.1 can I roll back the firmware or get an older copy of the utility so this can be set up? or is it just hidden in a difrent spot.

To follow along with the screen shots, you will need v5.6 of the AirPort Utility. You can download it directly from Apple here.

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.

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...

I have DHCPand DNS services in a router and I want to install domain controller

Hello
I have a sonic wall router managing the DHCP and DNS services for a my network and wanna keep it doing this.
I have a computer running windows server 2012 standard and installed active directory along with DNS. I also went to the DNS manager of these server and forwarded the DNS addresses of my router. For some reason I'm not able to join a client computer
into the DC.
I got this error:
An Active directory domain controller (AD DC) for the domain "mydomain.ca" could not be contacted.
Is it possible to configure active directory using the DNS and DHCP services of my router? or Am I doing something wrong?
Can somebody helping me with this matter?
Thanks.

Hello,
if the DNS server on your router is able to provide all required zones, SRV records and options that the DCs require there is no problem using 3rd party DNS servers.
But I would recommend that you u se the DC as DNS server also and just run the installation during the promotion process.
All clients MUST use the domain internal DNS servers on the NIC NONE else otherwise you will run into trouble. Internet access will be done via the FORWARDERS on the DNS server properties in the DNS management console on the Windows Server.

Creating a versatile DNS and redirection service on Snow Leopard Server

For the few of us who use Snow Leopard Server as a main DNS for our small network, the following is a workflow that I would like to share with the board for creating redirection services to not just sites found on the locally hosted apache but also external sites.
+IF you are adding a second domain name, the reverse domain lookup will not appear and you will need to add a Machine/A record with the fully qualified domain "domainname.com." (don't forget the . at the end) into the new zone and it will point to the "server" Machine/A record ip address.+
*DNS Portion* : (ServerAdmin > DNS > Zones >
Add Zone > Primary > Create a fully Qualified Domain name and dns "server" in the Machine / A Record
Create the (add Record > Alias/ CNAME) subdomain pointing to the server.domainname.com e.g. (library)
*Web / Apache Portion :*
Create a new site (ServerAdmin > Web > Sites > Plus button)
With General > host name exactly as spelled in above subdomain in full (library.domainname.com)
Select Web Folder where the site is hosted
If you are creating a redirection, create a folder on the server, add an index.php (with the script below)
Add Alias with the same subdomain as number 2
_PHP script :_
<?php
$location = "http://example.net";
header("Location: ".$location, "301 Moved Permanently");
?>
// Edit the "http://example.net" to which ever e.g. "http://apple.com"
_Alternatively you can also mask the page with :_
<html>
<head>
<title>Same Title As Your Homepage</title>
<script type="text/javascript">
function changeTitle()
if (top.frames['main'].document.title)
top.document.title=top.frames['main'].document.title;
</script>
</head>
<frameset>
<frame name="main" src="http://actual-url.anotherhost.com/page.html"scrolling="auto" target="main" ONLOAD="changeTitle();">
<noframes>
<body>
Place a suitable message here for people with browsers that can't read frames.

Ok, local DNS services (unicast DNS) are typically straightforward to set up, very useful to have, and can be necessary for various modern network services, so I'm unsure why this is even particularly an open question. Which leads me to wonder what other factors might be under consideration here; of what I'm missing.
The Bonjour mDNS stuff is certainly very nice, too. But not everything around supports Bonjour, unfortunately.
As for being authoritative, the self-hosted out-of-the-box DNS server is authoritative for its own zone. That's how DNS works for this stuff.
And as for querying other DNS servers from that local DNS server (or, if you decide to reconfigure it and deploy and start using DNS services on your LAN), then that's how DNS servers work.
And yes, the caching of DNS responses both within the DNS clients and within the local DNS server is typical. This also means that there is need no references to ISP or other DNS servers on your LAN for frequent translations; no other caching servers and no other forwarding servers are required.

Using DNS Services on an internal network and still using an outside DNS

I have just started using Mac OSX Server for the first time and I am trying to set up an internal DNS server so I can set up an LDAP Directory master and replica. However, I am running into some problems in setting up the DNS server on our network.
This is where it gets a little confusing to me here and i have to explain some things. We have a shared web hosting ISP, which means that our mail services and web hosting services are not hosted on site. To access our mail services using a FQDN I would point Outlook to mail.xxx-xxx.net. However, I want to use that domain, xxx-xxx.net, as our internal network as well because it is the name of our company.
I can get all of the DNS names to propogate to their assigned IP's on the internal network and can ping everything using fully qualified domain names, but whenever I go to use services such as mail., it cannot find the server which is hosting that service because it is obviously not on our internal network. This makes sense that I cannot ping it, but how do I set up the alias mail.xxx-xxx.net to point to the ip address of the mail servers hosted by our ISP instead of something hosted on our internal network?
Sorry I can't clarify better, I'll try some cliff's instead;
1) Trying to set up internal dns server so I can use LDAP Directory Master and Replica Services.
2) The domain, xxx-xxx.net is currently being used for web hosting and mail services not hosted at our site.
3) Want to use the domain xxx-xxx.net as our internal domain because it is the name of our company, and eventually we will be hosting our own content.
4) Can set up internal DNS server and get all IP's to propagate just fine, but services such as mail.xxx-xxx.net cannot be used because they are not hosted on the internal network.
5) How do I set up DNS to point certain services to point to an external DNS servers, or to the IP address of the server itself so I don't have to use the ip address i.e. mail.216.256.33.24?

HT1925 I cannot uninstall Bonjour and Quicktime so I can do a complete reinstall of iTunes. I get an error message stating that both are older versions and to contact technical support. I am running Windows XP Professional Service Pack 3.

I am trying to update iTunes on my desktop (running Windows XP Professional Service Pack 3) and I continue to receive an error message stating that the update cannot continue because Bonjour and Quicktime are older versions and to contact technical support. I have tried repairing both and tried to uninstall iTunes and all of it's componants and still receive the same message. Any help getting this issue resolved as soon as possible will be much appreciated.

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any Bonjour entries and click "Remove", as per the following screenshot:
Next, select any QuickTime entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

DNS required for NAT and DHCP services?

I have a 10.6.2 server with a static IP, domain name, working as a gateway (I have my reasons) as well as providing some services inside and outside. My ISP has a PTR setup so the domain points to the static IP.
My question is, do I need the DNS service running on the server? Based on some of the docs it tells me to put my ISPs DNS servers in both of my servers ethernet port settings, as well as in the DHCP profile to give out to clients on the network. When I do this, clients cannot resolve names. I can ping IPs from the client, I can even ping my ISPs DNS servers from clients, but I can't resolve names. When I try to dig anything it just hangs there with a blinky cursor.
When I have the DNS service running it's all happy. The only thing is, clients on the LAN experience some serious lag when accessing services on the server, UNLESS I configure the DNS for my domain on the server with both internal and external IP addresses. Is that how it is supposed to be?

In the server zone files, the dedicated IP address should point to the machine name, as in name.someserver.com. The local IP address should point to name.local. If you have more than one domain name, the zone files should show their network IP address, not the dedicated IP address, which should only point to the machine name.
As a side note, I strongly advise against connecting a server directly to the Internet. It should be behind a router with DMZ/NAT/firewall capabilities. By the time you realize why, it will be too late.

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.

Does apple have a dedicatrd DNS server?
I read a couple of articles stating that the google DNS servers like 8.8.8.8 and 8.8.4.4 slow down apple and facebook services.
Did a couple of tests like iTunes streaming and found out that its true in some cases.

Not always!

EA2700 Bonjour / Multicast DNS problem

I've just updated from a Linksys E2500 to an EA2700. The new software features are great, however multicast DNS (aka zeroconf / bonjour) service discovery is not working between wired and wireless connections. (Wireless to wireless is fine, just not to wired).
The last time I saw this problem was a crappy Dlink router about 10 years ago, and I have never seen it on a Linksys produce before now (3 previous modems/routers).
I have no issues connecting to the internet, or connect to devices by their IP addresses. The problem is the service discovery, which is used for things such as Airplay video mirroring, Time Machine backups (and file sharing), iTunes music sharing and more.
Has anyone else has any issues with bonjour service discovery from wired to wireless connections on the EA2700? Or, even better, found a solution?

Hi mattconnolly ,
Most of these Linksys Routers use DLNA/UPnP for network discovery. Zeroconf creates a local domain, so devices are discoverable through names like my router.local or canon printer. local instead of its local IP address. This has been implemented on new Linksys Smart Wifi line but only for accessing it's setup page (myrouter. local) - and there were times that it breaks.
You can try to turn off/on your router, but it doesn't really fix/resolves it. You can try also to update your device's firmware. The firmware latest release update is dated 11/19/2012 (1.1.39 Build 145204) and based on the release notes, there's a Fix for Multicast traffic issue on it's release version 1.0.14 (Build 129982). Other than this, you might want to check on a much more flexible operator - WRT1900AC.
Good luck!

Appreciate any help. Thanks.

This error message is telling you that SGD failed to find any site objects in your AD tree. This should not stop users from logging in, it will just mean that SGD will not be able to work out which AD site is local to the SGD server.
If you are not using sites in your AD setup, then you do not need to worry about this.
Hope this helps,

Do I have to run DNS service?

I'm wondering if I have to use the DNS service on OS X Server. I understand what DNS is but I'm admittedly in over my head with DNS and how to operate it properly on the server. We always have connection issues with various services within our office network that we don't experience anywhere else (ie: when we take the same laptop out of the office and use it on another network). I'm convinced it's the DNS setup on our server, which I'm sure has gotten messed up from all the poking around. But do we even need to be running this service?
The services we use on the server are VPN, iCal, File Sharing, and Blogs/Wikis. We have an airport extreme that serves DHCP router and our ISP supplied modem serves as our internet gateway and generic firewall (default settings).
Some examples of random access/connection problems we have within our office that we don't have elsewhere:
-email/web host access problems (new sub domains often do not appear unless we kill/reboot the DNS service)
-screensharing via iChat never works within our office network (not sure if that's DNS related or not, just another one of those things that never works within the office, but works fine when we take laptops outside of the office).
Any of this DNS related? Even if it's not, do I have to have DNS service running on our server?
Thanks!!

Bogus or buggy DNS can certainly cause issues, and so can a bad Ethernet cable or WiFi interference. Could be a misconfigured network. Could be somebody's corrupted the DNS configuration. Which of these might be the trigger in this case is difficult to say.
And no, you don't need to be running local DNS. But you do need access to DNS servers somewhere upstream of your clients, and your local boxes certainly can operate with either Bonjour (mDNS) or static IP assignments. Or with your own local DNS.
What the next step depends on your intent and your budget. If you want to learn and manage DNS, then Cricket Liu's DNS and BIND book is a good resource for learning. (And the CutEdge Systems DNS Enabler package -- though with a few weirdnesses aside -- has a more capable interface.) If you have somewhat more budget and less desire to learn DNS, then getting somebody in to verify and reconfigure (and secure) DNS is a valid approach.

MDNS/Bonjour port 0 service registration broken on Solaris 11 Express

I'm using Solaris 11 Express on x86-64, and found a pretty bad bug with registering mDNS/Bonjour services. Most service registration works fine, but registering a service that uses port 0 does not work. It claims to work, but the service never gets registered, and can't be browsed for.
It's easy to reproduce: in one window, run
$ dns-sd -B test.tcp
You should see 'Browsing for test.tcp', and no services found.
Then, in another window, run
$ dns-sd -R solaris test.tcp local. 0
to register a test.tcp service on port 0. It seems to succeed, but the first window doesn't show the new service.
Now, kill the 'dns-sd -R' registration process with ctrl-c, and run
$ dns-sd -R solaris test.tcp local. 1
This time, the first window will show the service. Registering on port 1 works fine, but port 0 does not.
Port 0 service registration works fine on every other OS, and many services use port 0 by convention if they aren't advertising an actual service. For example, netatalk can register a device-info.tcp service to mimic a certain Mac model (so your Solaris server shows up with an Xserve icon). This "service" uses port 0, and doesn't work on S11 Express unless the source is changed to a non-zero port.
Can someone test this out on Solaris 11 EA and other versions, to see if it's been fixed or not?
Edited by: 887058 on Sep 22, 2011 11:57 PM

It is registering fine with port 0. You can test by trying to register the same service on another host in the local network
with the same service name and port. You will see the service name automatically renamed.
For example:
root@estrada:~# dns-sd -R solaris test.tcp local. 0
Registering Service solaris._test._tcp.local. port 0
Got a reply for solaris._test._tcp.local.: Name now registered and active
root@testz:~# dns-sd -R solaris test.tcp local. 0
Registering Service solaris._test._tcp.local. port 0
Got a reply for solaris (2)._test._tcp.local.: Name now registered and active
^C
You can also query and see the SRV record for it:
# dns-sd -Q solaris._test._tcp.local. SRV
Timestamp A/R Flags if Name T C Rdata
23:38:58.949 Add 2 2 solaris._test._tcp.local. 33 1 21 bytes: 00 00 00 00 00 00 07 65 73 74 72 61 64 61 05 6C 6F 63 61 6C 00
It appears to me the service is not seen in the service browse call. These port 0 registrations are used to indicate the service
is not available on the host so this could be by design. I have tested the same on Mac OS X 10.6.8 and observe the same
results.

Compatible Dynamic DNS Services

Does anyone know about ANY FREE Dynamic DNS service compatible with the Dynamic Global Hostname settings in Airport Extreme (MC340LL/A A1354)?
My registar/hosting (DreamHost) doesn't allow dynamic dns updates, except through local shell or perl scripts, or APIs on the web server — as far as I know. Dyndns.com only allows it with Custom DNS Zones, which are not free. And I would rather not use those silly update clients.
Oh, and I'm not willing to pay $99/yr for a MobileMe account just to have my home.owndomain.com pointed to my dynamic IP. Ain't gonna happen!
Thanks in advance!

Hi, Tesserax. Thanks for the welcome!
I've been using DynDNS with a D-Link router, but it got replaced.
Their words:

Which means it CAN be done, but only with Custom DNS. First, I think $29.95 for just a pointer is a little expensive; second, I would have to move my DNS services from my hosting. Too much ado, so I'm looking for an alternative — without success so far. I just want something that uses DNS Update protocol and TSIG security.
Meanwhile, I set up an API from my hosting and a perl script running on the boot to check if DNS is pointing to the right IP. It just works, clean and simple. But it's not a built-in solution and I cannot take advantage of wide area Bonjour, for example.
So, if does anyone know about it — a free dynamic dns service that uses DNS Update protocol and TSIG security —, please let me know.
Thanks,
Gui
