DNS - Service Record .. ?

What is the use of Service Records, and wich service records do we have .. ?
I have set up my three servers with DNS but not using any Service Records.
Do i need to use them or not .. ?

John,
Your direction was helpful, but at this point unable to locate the entry to edit.  Attached is a screen shot.  Can you suggest a folder that may contain the entry?

  • 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.

  • 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.

  • 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.

  • 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

  • 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.
    Peter C. Hesse Network/Systems Administrator

    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 -autounlock -enable Driveletter:

  • Unable to run the application via DNS CName record.

    I have  Windows Server 2008R2 running an application that connects to a database via a DNS CNAME record. The application was working fine until after yesterday when it could no longer
    connect to the database. The database server is up and running without any issues. You have verified remote connectivity to the database server from your workstation.
    How would you troubleshoot the issue and what are the steps to resolve it?

    It might be that the application does not support using aliases for DNS resolution. You will need to contact your application developer/vendor for assistance.
    To make sure that DNS resolution works properly from the infrastructure level, you can simply use
    nslookup and make sure that the resolution is done properly.

  • 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.

  • DHCP Reservation Sync and DNS Host record sync etc shown in IPAM GUI

    Hello all,
    I am aware of the scripts in the TechNet script center to sync DHCP leases etc to IPAM, however my question is about something else -
    If you highlight an IP address (IP address inventory->select an IP), You can see fields that say: "DHCP reservation sync", "DNS PTR record sync" and "DNS host record sync" as below:
    I was curious as to what these are for. Is there some built-in sync functionality for these that I perhaps have not enabled? (Don't see such options any where..)
    thanks,
    -Ravi

    Hi  Ravi ,
    The three columns tell us the information of the synchronization between IPAM server and DNS server (or DHCP server) .
    Here is the detailed guide for using IPAM :
    Using the IPAM Client Console :
    https://technet.microsoft.com/en-us/library/jj878351.aspx#inventory
    IPAM can sync DNS and DHCP records .
    The IPAM database is separate from DHCP and DNS servers on our network ,and full synchronization of hosts and IP addresses between IPAM and managed DNS or DHCP servers does not occur automatically
    unless we have configured automated tasks to perform this synchronization .
    For detailed information ,see
    DNS and DHCP record synchronization chapter in the following link :

  • DNS "A" Record Preventing Networked Users from Seeing Own Website

    I just set up a DNS "a" record in Server Admin to point "mail.xyz.com" to my server's internal ip (10.0.1.1).
    I did this so users could stay on the network with sending and receiving mail, as opposing to going out onto the web to do so. (I have MX records on Network Solutions point "mail.xyz.com" to my server's external ip.) All of their mail clients list "mail.xyz.com" as the mail server, instead of the server's internal ip.
    Trouble is, when users on the network try to access our website, "xyz.com," their browsers now return an error, saying they cannot find the server.
    Any idea?
    Lost count   Mac OS X (10.4.9)  

    Steve and David --
    This works. I am using Server Admin. To reiterate, I
    added a zone "mysite.com" and a primary server "mail"
    and pointed it at my server's internal ip so my users
    can stay "inside" while checking mail.
    Then, to follow your suggestion, I added a machine
    named "www" to zone "mysite.com" pointed to my
    server's external ip.
    Some questions: How can I be sure the client's
    machines are going interally to the server for mail?
    (When I dig it in terminal, "mail.mysite.com" returns
    an "a" record for the server's internal ip -- I
    suppose that is sufficient.)
    Yep!
    Should the primary name server for the zone be "mail"
    with "www" as an added machine, or vice versa?
    The primary name server just identifies the machine which is responsible for holding records for that zone (domain). Add www as a 'machine' - think of each 'machine' as a specific IP address which identifies a host, hence IP / Name partnership. Any other hostname on same IP is an 'alias' (which becomes a CNAME record in the dns file).
    You say I have to do this with "any record hosted in
    my public dns as a mirror." I am running three
    websites from my server, all with public dns pointed
    at my server. (I use the same mail
    server--mail.mysite.com--for all three.) Do I need to
    set up a "www" record for each website? I have no
    problem accessing the sites from internal client
    machines.
    the basic issue is that any zone (domain) defined in your own dns becomes 'authoritative' for that domain. So when clients ask your internal dns about any zone (domain) which is defined in it, and your server does not have that record, it will respond with "no such record" and your clients must take that on face value.
    Therefore, you only need to mirror records for domains which you have defined in your own dns. If you have external www.domain1.com and www.domain2.com but only have domain1.com established on your internal dns, then you only need that domain's www record mirrored. Your server will therefore not be authoritative for domain2.com and will pass all requests out to whichever external dns is authoritative for it.

    Okay, so you think we should try putting "mail.ndhc.org" into that section (Hostname/DNS "A Record" name field) instead of what we currently have "ndhc.org"
    But that error doesn't sound like it's related to DNS. It much more
    sounds like you're really blacklisted for sending spam. If it's really
    the hostname, then their system is giving out extremely stupid result

    I know when we first setup the system we were having an issue with the GWIA relaying, but that has since been rectified, they are the only ones that are blacklisting us, because I have checked on other sites (blacklisting websites that is) and there is nothing about our site being blacklisted. I think basically the people that are trying to receive the messages respond back saying that they never received emails from the people here at ndhc. If memory serves they have been emailed from other accounts and those go through because Bellsouth.net is not blocking those accounts, like yahoo, gmail, etc.

  • Running DNS service for SCAN in the openfiler VM

    Grid version     : 11.2.0.3
    Guest OS     : Oracle Enterprise Linux 6.3
    Host OS          : Windows 7 (64-bit ) with 16gb Physical RAM
    Hypervisor : Virtual Box 4.2.6
    Openfiler version : 2.99
    Using virtualBox, I am setting up a 2-node RAC node on Oracle Linux.
    I have a 3rd VM which runs openfiler ( NAS )
    For using SCAN feauture, I would like to run a DNS service as mentioned in the article below
    http://www.oracle-base.com/articles/linux/dns-configuration-for-scan.php
    I don't want to run the DNS service in any of the two RAC nodes. Instead of creating a separate VM just for the DNS , I am thinking of running it in the Openfiler VM.
    Openfiler is running in a Linux Distro called rPath. I am not sure if the packages mentioned in the above oracle-base.com article is available in this distro. Has anyone run a similair DNS service in the Openfiler OS ?

    I doubt it.  OpenFiler is a "stripped-down" OS.
    But Wait ! A Google search returned this : http://www.denbraber.org/?p=4

  • 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.
