HB3 / Dynamic DNS Update time

Does anyone know;
1. What the default update time is on the dymanic DNS settings and
2. is it possible to amend it?
thank you

If you mean can you alter when your IP changes no I don't think you can. I have had one for 6 weeks and the next for a few days. A

How to Configure bootpd to Perform Dynamic DNS Updates

I have been able to get bootpd configured to function as a basic DHCP server. I would now like to configure it to dynamically update DNS forward and reverse zones when leases are assigned, released, or expired.
Does anyone have an example of a bootpd.plist file to configure bootpd for dynamic DNS updates?

Hi,
I am not sure what you are attempting to configure here.
But what the NAT configuration above does is do a Dynamic PAT for all the servers on the "firewall-dmz" to a single IP address towards the "firewall-outbound"
This Dynamic translation doesnt however enable connections to be initiated from behind the "firewall-outbound" interface. When your hosting a server which needs a NAT towards the users then the NAT type has to be Static NAT or Static PAT.
Static NAT will essentially use up one public IP address for just the single local host/server.
Static PAT will do a Port Forward from the public IP address and public port to the local IP and local port. And this is most commonly used with environments which only public IP address is the one that the ASA holds in its WAN interface.
A typical Static NAT configuration is this
static (inside,outside) 1.1.1.1 10.10.10.10 netmask 255.255.255.255
Where
inside = is the interface behind which the host is
outside = is the interface towards which the host is NATed
1.1.1.1 = is the public NAT IP address for the host
10.10.10.10 = is the local IP address of the host
A typical Static PAT configuration is this
static (inside,outside) tcp interface 80 10.10.10.10 80 netmask 255.255.255.255
Where
tcp = specifies the protocol for which the Static PAT configured
interface = specifies that we will be using the public IP address of the destination interface "outside" as the public IP address for this single Port Forward.
80 = first "80" specifies the public port visible to users behind the destination interface
80 = second "80" specifies the actual local port on which the local host is listening on
Hope this helps

DHCP dynamic dns updates for Chromebooks fail

Hi all,
We're having a bit of a problem here. We have a domain here, domain.local, that has approximately 260 Windows Machines (XP, Win7, various MS Servers) and we also have users that bring in iOS devices, Kindles, Androids and so-forth. The domain controller
runs dhcp, dns, wsus, and is a file server. We only have a single dhcp server and a single dns server on a Windows Server 2008 R2 box.
We have a wireless network by Aruba that has three SSID's on it. One is secure, two are firewalled and open. You can ping the chromebooks on either of the wireless networks. the DHCP server works find on all of these.
We started off getting bad_address entries from the chromebooks when they went on our network back in September. Creating a dhcp lease solved most but not all. We are still getting dozens of entries in the dhcp log that specify bad_address. We have the dhcp
server testing twice before issuing. Once in a great, great while, we might get something on an Android, but that is it.
Funny thing is, Chromebooks are being handed IPs (horray) and we can see the leases in the dhcp server. Well that really isnt funny, but what is, dynamic updates to dns are not happening. They exist nowhere in the forward zone or as a reverse pointer.
Kindles, iOS machines, Androids, Windows machines and everything else work flawlessly.
So two things... bad_address in the dhcp area and the dhcp dynamic updates are not happening for the Chromebooks.
Dns is set to "Always dynamically update DNS A and PTR records.
Discard A & PTR records when lease is deleted is checked.
Dynamically update DNS A and PTR records for DHCP clients that do not request updates is also checked.
Name protection is turned off as of today.
Any Ideas?
Thanks!
Steve

The chromebooks are not joined to the domain. They are not designed to do so.
DNS Suffix is fine.
We have intermittent issues with Androids and an occassional iOS device, but never Windows machines.
Here is part of the log from yesterday. Only two bad_addresses happened today. See what I mean by it's intermittant?
Thanks!

RW215W Dynamic DNS update interval

Hi,
I have a RW215W Router. Using a mobile broadband dongle for internet connection and the public ip changes every time the dongle is connected. I´m using a ddns service. I need update the new ip to the ddns service more frequent or when ip changes. Is this possible? any suggestions?

Hi,
Please check if your multiple DHCP has joint the group DnsUpdateProxy or not. To do this, you can refer to:
DNS Record Ownership and the DnsUpdateProxy Group:
http://technet.microsoft.com/en-us/library/dd334715(WS.10).aspx
Also check if the client service “DNS client service" is running fine.
Meanwhile, please refer to these articles:

Dynamic DNS updates and issues with re-imaged / replaced machines with the same computer name

Our AD team gets asked frequently to delete bad DNS entries because a computer was replaced or VDI was re-created, and when it was joined to the domain it had the same computer name but different SID, so the DNS entry for that computer can no longer be updated
to a new IP address because the new computer doesn't have rights to update that object in DNS.
I recently saw a resolution to this was to set the security for DNS to allow updates from "Domain Computers" as described in the KB below.
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2005210
Has anyone done this? Any negative implications from this?
Thanks

Granting all domain computers write access to all records in the dns zone does solve the problem. On the negative side, DNS security is reduced significantly. For example, any user with admin rights locally on his/her computer will be able to sabotage
services in your domain by deleting or changing host records of domain controllers, servers or other client computers.
A more secure solution in this case will be configuring DHCP servers to update DNS on behalf of the client and granting DHCP servers appropriate access to DNS zone. Take a look at
Configuring Secure Dynamic Update for more info.

Dynamic dns update client for archbox behind router?

I tried ez-ipupdate but i found out it cant work if youre behind router....anyone know any i can dload that do? :oops:

RahJiggah wrote:I tried ez-ipupdate but i found out it cant work if youre behind router....anyone know any i can dload that do? :oops:
Yeah, that one just don't cut the mustard. Try "ddclient". I started a thread a long time ago comparing different dyndns clients, and found "ddclient" had the richest feature set, including a lot of support for you router folk.
Try this thread.

OS X 10.6.1: bootpd, named, and dynamic DNS zone updates

I have OS X 10.6.1 installed on a Mac Pro. It is configured to be the name server and DHCP server for my home network, i.e. /etc/named.conf and /etc/bootpd.plist have been modified to provide these services.
I've encountered no problems with either the name server or the DHCP component of bootpd after upgrading to OS X 10.6(.1); however, one thing that continues to bug me is how to configure bootpd to dynamically update the DNS zone files whenever a lease is issued, released, or expires.
At work, I use the Internet System Consortium's DHCP software and have it configured to dynamically update DNS whenever leases change state. I would really like to have DNS done the same way at home.
What changes need to be made to /etc/bootpd.plist that would allow dynamic DNS updates to occur?

Did you ever get an answer to this? Would rather not change the DHCP server in Snow Leopard....
Thanks

Dynamic DNS (via DHCP) out of the box?

Greetings!
I was just wondering... Does OS X support Dynamic DNS updates out of the box?
I can't seem to find any confirmation if 10.5 uses bootpd (which I think it does), and if bootpd supports dynamic DNS updates with the named service built into Leopard Server. There don't seem to be any options in Server Admin to enable this... So I'm a little hazy as how to enable dynamic DNS without compiling my own version of ISC-DHCP.
Just for clarification here; what I'm looking for is the ability to update a DNS zone with a PTR/A record(s) of machines that send a hostname as a part of retrieving a IP address from a DDNS-enabled DHCP server. Ie, "mybox" requests IP from DHCP server, DHCP server updates "mydomain.tld" with a record for "mybox", so that "mybox.mydomain.tld" is resolvable afterwards by the machines on this subnet.
Cheers,
-SC

This is a strange topic because implementing Dynamic DNS on Mac OS X Server looks like it should be child's play... so why hasn't Apple done it? Could it simply be that Apple sees no need for it at this time? Mac OS X clients don't need it to sit happy with a Mac OS X Server. Neither do Windows clients using a Mac OS X Server PDC.
Apple has implemented Dynamic DNS client support into the Active Directory Plug-in in Leopard. In this environment, of course, the client's DNS server is most likely to be an Active Directory-integrated DNS server which happily support DDNS. Unfortunately this Dynamic DNS facility is not immediately available to those not using the Active Directory plug-in.

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

DNS update automatic

Dear all
I have one server running Windows Server 2008 R2 and that is part of our AD domain. This server is getting 2 network interface with IP addresses in 2 different VLANs. We would like to have only one IP address added to our AD DNS but unfortunately, every
day the DNS server is adding 2 entries for the 2 different IP addresses of that server.
I have unselected the value "Register this connection´s addresses in DNS" for the 2 network interfaces. This has not prevent the DNS update the next day.
I have created an entry DisableDynamicUpdate in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters and put a value of 1. This has not prevent the DNS update the next day.
Do you know what else could be done to fix this issue? Having the 2 entries is making some other applications failing.
Thanks in advance
Best regards
Yann

Hi,
Did you have DHCP server in domain?
Dynamic DNS registration relies on the Dynamic Host Configuration Protocol (DHCP) client service to perform dynamic updates. When you disable or set the DHCP client service to start manually, it prevents dynamic DNS updates from occurring.

How can i configure a dynamic dns at a time machine

Hi All,
I have a time machine at home, with Airport Utility version 6.1.
I'm currently trying to configure a dynamic dns at the airport itself but I don't have any luck in finding the functionality to do so. Couple of questions:
1) Do I really have to install the previous versions 5.6 Airport Utility to configure DDNS?
2) I assume if I can't use the previous versions of Airport Utility then I would need to use a Dynamic Update Client. My No-IP Dynamic Update Client doesn't seem to be running on MAC OS X Mountain Lion. Is there any other developers that provides a domain for free and the DUC is actually working on OS X Mountain Lion? (E.g. I heard that DysDNS doesn't provide an entirely free service anymore)

I think you mean Time Capsule not time machine.. TC is the hardware .. TM is the software backup program in the computer and has nought to do with DDNS.
There is no DDNS client in the TC.. never has been. Apple must have some private system for icloud to work.. but no access is allowed to it by users. As with all things apple it is designed to ensure you are able to use icloud or nothing.
I am not on ML or even Lion.. good old SL is fine to me.. and far better networking.
I presume some of the dyndns providers will offer a client for ML now..
All of the free services are trying to sell you something.. and constantly harras you.. no free lunch in this world.
The easiest method and to escape the upgrade cycle.. just get another router.. almost every router in the world provides several dyndns clients built in. The router is where this should be done. so the computer can stay off. Just bridge the TC and port forward to it. Simple and cheap.

RV042 Dynamic DNS not updating automatically

I purchased 2 RV042's (h/w version 3) less than two months ago. I updated them to the latest firmware (
v4.0.4.02-tm (Jul 4 2011 13:30:56)), did a factory reset to make sure I was working with a clean slate, set up DDNS through DynDNS and a site to site VPN between the two. Everything was working great for a month, then the DynDNS accounts expired because they weren't being updated.
I reactivated the names on the DynDNS site, and started to monitor the "last updated" date and time. After 24 hours there were no updates according to the DynDNS site. I logged into one of the RV042's, and it said "Dyndns Enabled : Dynamic DNS is updated successfully." This is a stale message from 24 hours ago when I hit save.
So I went into Setup | Dynamic DNS | Edit Config and there it also says "Dynamic DNS is updated successfully." I clicked "Save", status changed to "
Dyndns Enabled : Updating..." for a few seconds, and then back to "Dyndns Enabled : Dynamic DNS is updated successfully". I refreshed the DynDNS website and it shows the current time (in eastern time, i'm pacfic) as the last time it was updated. So it works when I manually hit the "Save" button. Not making any changed, just hitting "Save".
I've let the other RV042 go over 48 hours and it still hasn't updated.
So it apears for the time being, I'll have to remember to push the "Save" button once a week to prevent my DynDNS accout from expiring.
Does anyone have DDNS working in the lastest firmware and h/w version 3? If so, what is the update frequency?
I'd like to hear any suggestions on how I might be able to fix this, or if this needs to be fixed in the next firmware release. Hopefully, I've explained my problem clearly.

Jasbryan,
I am experiencing a problem with DynDns updater too. For me it seems that the updater (after a public IP change or reboot) only tries to update once, and if it failed then gives up and never tries again.
I have to update manually (pushing the update button) which sooner or later succeeds. (Sometimes the first trial is successful, sometimes only the second or third.)
I have an RV042 (v3) with firmware at 4.1.1 and a DynDns Pro subscription.
I have a site-to-site VPN between two RV042s, both with dynamic IP. When the VPN tunnel drops, I usually detect that one of the public IPs has changed and the router for some reason failed to update DynDns. If I do it manually pushing the update button (one or more times), the tunnel comes up of course.
Again, I suspect the problem is with the updater's "strategy" and timing. Should it wait a bit more after detecting a new public IP and retrying in every 5-10 minutes after a failed update attempt it would be more reliable.

Using Airport Extreme 802.11n to update automatic IP for Dynamic DNS ???

Hello,
does anybody now if it is possible to use Airport to forward the recent IP address to DynDNS.com ? As most routers are able to forward the IP to a provider like DynDns eachtime when IP address is renewed . I have found at the Airport Configruation Utility in the manual configuration the following fields: Button Airport -> Button "Basic Station" next to the field Airport extreme name the Button "config" -> a new pop up opens and at the bottom I am able to activate "dynamic global hostname" and to fill in the user ID + password. But the IP address is not updated at DYNDNS.com
Has anybody experience with Dynamic DNS and Airport extreme ?
Thanks in advance
Stephan

You may want to try using the DynDNS update client for Macintosh. http://www.dyndns.com/support/clients/mac.html

Programming error in HH2 software: Dynamic DNS

Advanced Settings >>Broadband >> Dynamic DNS
When you try to add multiple hosts the behaviour is very erratic.
I am testing some websites I am building and need to have 3 host names in the list of multiple hosts.
The first two went in OK ... after some funny behaviour.
They have been working fine for months: keeping DynDNS informed of changing IP addresses whenever I restart my HH2.
But the third one ...
I can add it to the list of supported hosts successfully ... for a mo ... by using the text field under "hosts supported".
It gets added to the list but then it disappears as soon as the "Apply" button is clicked.
At the same time the HH2 admin program won't forget an old hostname in the "Host" text field which I have not been using for weeks; have deleted from the list of multiple hosts and have deleted from my DynDNS account.
The routing via DynDNS works fine for all 3 current hostnames, but I just can't get the HH2 to accept the third one which means that when I next restart my HH2 I'll have to go to DynDNS website and update the IP address of the 3rd host myself manually.
I've tried every thing I can think of; also tried it in several browsers: Safari, Firefox, Opera and IE8; emptying browser cache. Finally concluded that there is a programming error in the hub software (Software version 8.1.H.J - Type A) on this page.
Shame ... in all other respects the HH2 is truly a brilliant piece of equipment.

I have tried that already, as well, and it did not work. However, the error message now tells me that the cabinet file "iTunes.cab" (rather than "QuickTime.cab" as it did before) required for this installation is corrupt and cannot be used. This could indicate a network error, and error from reading the CD-ROM, or a problem with the package.
