Making mini.dandyserver.us a public DNS

Hello out there,
fairly new to DNS and server config. I have the registered domain dandyserver.us, with godaddy.
My Mac mini server is behind an extreme and connected to comcast ISP. What I want to do is have the server accessible to WAN. SO I suppose my question is how do I setup the server, or godaddy, to make it public?
As it stands, mini.dandyserver.us resolves to 10.0.1.199.
thanks.

You have no public DNS translations.
There is no A (machine) record for mini.dandyserver.us presently listed in the public DNS; I just checked that with a dig command, as described in some of the troubleshooting documentation I've linked to.
You're likely getting an unknown-host error for attempted accesses from outside your LAN.
Kindly re-read the web pages I've previously referenced. If that material does not make sense, please (and so that I might improve it) indicate specifically what's confusing you.
And your ISP may or may not allow inbound server-oriented connections.

Internal and Public DNS conflict breaks mail

History:
We set up a new Mac Mini Server to replace our existing Server. The Mac Mini Server is setup behind a Time Capsule, which acts as our router and DHCP server. It also acts as our firewall on the public IP address and forwards mail to our internal server. Our situation is almost identical to the example situation on page 18 to 19 in the 'Getting Started' guide.
Our ISP acts as our DNS server and they host our public website. They also used to host our mail, but we have now moved the mail to our new in-house server. We asked our ISP to update their MX records to point to our static public IP address. Public DNS records for server.mydomain.com also resolve to this IP address.
When we originally set up the new mac mini server, the ISP had not yet updated the MX records. I am wondering if this affects how the Server sets up DNS on the local server machine?
Issue:
The local server machine on the local LAN is called server.mydomain.com, which resolves via local DNS (hosted by our server) to the server's internal IP address. (The local DNS server was setup automatically by the Server during initial installation / setup.) This conflicts with with public DNS records which identify server.mydomain.com with our public IP address at 205.200.19.225. This somehow causes confusion for the server which consequently seemingly randomly resets our domain (mydomain.com) and host name (server.mydomain.com) settings under Mail settings - which breaks our mail service. (We then edit these to the correct settings and all works again.)
I spoke to an Apple tech and they advised that we reinstall the Server operating system, using a local server name that differs from the public name. e.g. server.mydomain.lan (local) vs. server.mydomain.com (public).
*This may seem like a dumb question*: Would it be easier to keep our local host and DNS set up to server.mydomain.com and then rather have our ISP change the records for our public address / IP to mail.mydomain.com or public.mydomain.com? If we could make the change via the ISP's records versus our own, then it would save us a lot of work.
*A second potentially dumb question:* Since we rely on our ISP for DNS name servers, could we delete / stop the local DNS server for the local network and just use straight IP addresses instead?
*Plan of Action:*
Assuming that there is not an easy fix via the ISP's DNS records, then I'll reinstall the operating system and use server.mydomain.lan as the local machine and domain name. If I do this, then what should I be using as the domain and host name settings in mail? .com or .lan?
Should there be any need to manually configure DNS settings to make Mail work?

Mr Hoffman and Corbywan - thanks for the interesting and educational discussion. I must admit that I am still a bit confused and would appreciate any further help in understanding this issue!
*My situation:*
- Server on a LAN, which sits behind a Time Capsule router.
- The Time Capsule router serves DHCP and Internet to the LAN and sits on our public static IP Address.
- Our ISP has set up MX and domain records to forward public requests for our domain to our static IP address.
- Time Capsule acts as our firewall and forwards Mail and other incoming services to our internal server via port forwarding.
- Local DNS service is provided by the local server so that it can provide services to the local network. Non local requests are forwarded to the ISP DNS service.
*The problem*
We seem to have established that Snow Leopard Server breaks when the internal domain name matches the public domain name, because of conflict between the internal and public DNS which resolve to different IP addresses for the same domain.
*The solution*
I am looking for the easiest and most basic way to fix this problem. My understanding is that the simplest would be to reinstall our Snow Leopard Server to a new and different local domain name.
I am thinking of using server.example.lan for our local LAN domain name - which would be resolved to our private IP address via local DNS on the local server. I would be keeping server.example.com for our public domain name - which would be resolved to our public IP address, which would be forwarded from the Time Capsule to the internal server.
Now where I start getting confused is this: If Snow Leopard Server requires a Fully Qualified Domain Name to do things like send mail, then do I need to register my internal domain name? And how would this resolve from a public DNS server to the internal private IP address? Or is it more an issue where as long as the internal (albeit 'fake') domain name does not conflict with an existing public domain name?
*Other items:*
After setup, I will verify that Snow Leopard Server has setup our local DNS correctly for local DNS service.
If I understand correctly, I would set up Mail Settings - 'Domain Name' as the local domain name: i.e. example.lan and I would set up the Host Name as server.example.lan - is this correct? Would this work if these are not FQDN?
How does the mail server reconcile these local domain names with the public domain names? I assume that I need to check the box at Mail - Settings - Advanced - Hosting: "Include server's domain as local host alias" ? Or would I manually add an alias to the Local Host Aliases under the same tab?
Thanks!

Use of Public DNS Server

I have an iMac, Mac Mini and a Macbook Pro connected to a Airport Extreme Base Station. I normally use a Public DNS Server and I am not sure where to put the DNS URLs. Do I put them on the individual computers or is there somewhere in the Airport Extreme Base Station that they go? where ever they belong please provide location and instructions. Thanks.

Configuring the AirPort Extreme with the DNS makes it so that you do not have to configure each individual computer on the WLAN, the DNS settings will be handed down to the devices when they are given their internal IPs, but as long as the base station does not have a competing/conflicting DNS setup, configuring each individual device, as suggested by Carolyn, works also.
However, something strange can happen sometimes when you use a public DNS setup. I use the one Carolyn suggests, OpenDNS, but I cannot access any of the webpages of my ISP with this configuration. I have Todo en Uno (All in One), a service that provides cable, telephone and internet service from my local cable company, CableVisión. So with the OpenDNS setup I cannot configure the digital options for my telephone service, such as blocking and unblocking Int'l long Distance calls. I have to remove the OpenDNS setting to do so. But I created a work around using Locations in the Network settings. I have one Location with my ISP's DNS settings and another Location with OpenDNS settings. I can quickly switch between the two when I need to access my ISP's website.

How to configure Exchange 2010 to use a certain MX record that is unavailable with public DNS

Dear all,
as for TLS encryption I'm required to send emails destined for a certain domain via a dedicated send connector that has TLS encryption enabled/enforced. Thing is that the recipient's corresponding domain MX records cannot be resolved using public DNS. As soon
as I verify MX records for the recipient's domain using nslookup I only receive MX records that do not accept TLS. In order for TLS to work I'm required to send all outgoing emails to that specific domain via a certain predefined host, i.e. MX record, that
is known to me and Exchange needs to know as well. But how can I configure Exchange to use a certain MX record (that resolves to mxtls.<domain>.com instead of mx.<domain>.com without being available in public DNS?
Editing the hosts file directly on the Exchange server? Not an option, right?
Messing with my ADS integrated DNS not an option, too, as I then have to add all sorts of entries for that zone, e.g. www and stuff like that, to make it work?
I'm lost here, any help would be greatly appreciated.

Well, I figured it out by myself. I just had to add the corresponding server, i.e. mxtls.<domain>.com, to the Smarthost configuration for the corresponding Send Connector and set its RequireTLS setting to $True.

Exchange 2013 CAS DNS Round robin Public DNS Record

Dear All,
If I am going to use DNS round robin as CAS redundancy. How should I map the public DNS record? Do I need to map 2 public IP for 2 CAS server to the mail domain? THanks
Best Regards,
Elroy

Dear Elroy
I am not sure about the success rate of your implementations but yes if it is round robin what you require you need add 2 ip addresses.
Suggestion:
Why don't you implement a CAS with a load balancer and then you can map the Public IP to the one IP on the Load Balancer.
Good Luck.

Use Google's Public DNS Server To Fix Apple TV Streaming Problems

Many people have been having a streaming problem with the Apple TV - especially with Netflix. In fact, it's often the most popular topic on this forum. After having the same problem off and on for two years, I finally figured out the following solution. It uses Google's public DNS service instead of your ISPs DNS.
1. Navigate to Settings >> General >> Network and select Configure TCP/IP.
2. Select “Manually” next to Configure IP.
3. Dont change the IP address or the Subnet Mask and Router Address. Just click "Done".
4. Set the DNS Address screen with the following: 008.008.008.008 and click “Done.”
You should now be able to stream more smoothly on your Apple TV.
This problem is probably caused by a bad streaming server somewhere on Netflix's CDN (Content Delivery Network). The DNS points your Apple TV based on location. By using Google's DNS, you get a different streaming server. That is, of course, a wild guess and is not verifiable by me. But, it makes sense so I'm going with that.
If this works for you, please buy a cup of coffee for a complete stranger or some other selfless, random act of kindness.

Welcome to the  tv Discussion Forums.
Barring interference to the network (which is probably unlikely but not totally out of the question) I'd agree that your problem seems specific to one mac. IMHO reinstalling an OS is more often than not a lazy mans way of saying they can't be bothered to look for the problem and totally unnecessary so far as I am concerned. I don't believe any version of itunes has been a problem for the tv, although there have been the usual problems posted that usually accompany any upgrade (these are more than likely due to updating over damaged files).
Reinstalling itunes will replace the application but not many of the associated preference files that are more likely to be a problem than the application itself. Rather than reinstalling itunes, I'd try creating a new user and try itunes in the new user account to see if the problem persists.
You could also create a new library in the original user account and see if you have similar problems with that library.
Check your network settings and compare them to the other macs that work OK, check for proxy servers and DNS addresses.

Lync Edge and Proxy server public DNS records port forwarding rules

Hi All
I have question in regards to port forwarding rules for port 443 of simple url.
I have 4 public ip addresses.
1 edge server (4 nics , 3 running with different ip for sip, meet and dialin in DMZ network, 1 connected to internal local network).
1 proxy server (2 nics, 1 running with an ip which is in DMZ same as edge, and 1 connected to internal local network)
1 front end (lync 2013 standard installed.) connected to internal local network
1 office web apps . connected to internal local network
The question is that I am using 3 public ip addresses respectively on public DNS records for sip, meet and dialin(av) and using port 443 which has been set on edge server. So , I can use 3 DMZ network ip address on edge for sip, meet
and dialin (av) port forwarding from 3 public ip addresses as per in Microsoft document.
However, I also have a reverse proxy .Hence, my understanding is all public DNS records except SIP and port 443 should be pointed and port forwarded to reverse proxy ip address which is in DMZ network as it would redirect 443 and 80 to 4443 and 8080 to front
end.
Now the question has been clear, if simple URLs public DNS record and port forwarding rules for port 443 should be pointed to reverse proxy server, why they need to be set on each ip address and port number in Front end server topology to edge server?
If anyone knows, please give a help how to set it correct and what is supposed to be a correct configuration for a topology lync 2013

Hi George
Thanks for your reply. Attached is my topology which could make my it bit clear. You may see the public dns host record from the image. I set sip, meet, dialin , and owa 4 host records. The first 3 records are pointed to lync edge by doing a NAT with port
443 which is the same as per you said. However my understanding is they should be pointed to reverse proxy instead as for instance, I need meet.xxx.com with port 443 to be redirected to port 4443 through reverse proxy server to the front end. So when the external
customers who do not have lync client installed to their machine then we can shoot a lync meeting and send to them via outlook and they just need to click on join lync meeting link in the email to join in such a meeting based on IE. (Is my understanding correct?)
If lync web meeting works like so , then the question is why I need to set three SAME addresses in front end topology builder for edge and make them point to edge server instead?　
１. Access Edge service (SIP.XXX.COM) ---> I understand that it is used for external login lync front end.
2. Webconf edge server(Can I set to meet.xxx.com which is the same as simple URL that points to reverse proxy?) ----> If I can set this address to be the same as simple url address that points to reverse proxy, why should it need to be NATed to edge
instead? TO BE HONEST, if I HAVE tested, if I set this url as sip.xxx.com which means to use a single FQDN and ip address with port 444 and points simple url meet.xxx.com to reverse proxy, it will still work to join lync meeting sent by
outlook.I DO NOT REALLY UNDERSTAND WHAT this URL used for at this stage.
3. AV edge --- same as webconf

Public dns with Oracle AMI

Hi All,
I have created an AMI from ami-47613002. It ran fine and created an oracle database. When I logged in to EM i found following in the properties.
Oracle Home          /u01/app/oracle/product/11.2.0/db_1
Host          ec2-xx-xx-xx-xx.us-east-1.compute.amazonaws.com
Listener          LISTENER_ec2-xx-xx-xx-xx.us-east-1.compute.amazonaws.com
This means it is bound to public DNS of my amazon instance. Next time when i shutdown and start the instance, it will change the public dns. will that affect my db and listner?
Thanks

I guess.... however it is a guess.... is that ec2-xx-xx-xx-xx.us-east-1.compute.amazonaws.com is bound to your server and will not change after a reboot....
-xx-xx-xx-xx- is most likely a unique value bound to your server, so it should be fine. Please do inform us if this is the case. I am interested in your results.

Cloudflare Public DNS and Internal AD Domain DNS conflict?

I have a client whose web design team is using cloudflare for their public nameservers. At the clients location, we have an active directory domain with several servers, and we are running internal DNS for their domain (lets say "client.com" is the domain).The problem I'm seeing is that since PC's in their office need to point to internal DNS, every time CloudFlare changes the IP address of their website -- which seems to happen at least every other week, sometimes multiple times in a week, I have to manually update my internal DNS records with the new IP addresses so that the website is accessible again from within their office. Obviously those that are outside of the office have no problem since external users are looking to public DNS servers that then point to the cloudflare nameservers. But I'm not sure how to make this happen...

RRAS disable public DNS installed same Machine

Hello
last chance after reading and trying a lot of things.
A windows Server 2012 R2 with two interfaces one for public and other for internal LAN. With only DNS and Remote Services Role installed. When RRAS routing with NAT is active external queries to DNS are blocked; just really no way how to fix it.
For completeness I attach all technical information:
NIC 1: public ISP IP, with no gateway and no DNS configured, Only TCPIP/v4 enabled no other services like windows client services, shared and so on.
NIC 2: internal Lan , with ip 10.0.0.1 mask 255.255.255.0 no gateway no DNS configured. As before only tcpIP v4 configured .
RRAS configured following the wizard selecting NIC1 as internet connected and letting all the rest as "next->next".
firewall is disabled to avoid any interference.
Dns is configured with one zone for testing, just listening on the NIC 1 interface and disabled forwarding and recursive. The rest of DNS configuration is "Next Next".
Also I check that RRAS is not dropping packets executing: netsh ip routing show filter.
Please any help is much appreciated.

Hi,
You said that all these tests has been checked. So, what's the result?
Is UDP port 53 blocked? What does nslookup say?
Also, please perform a network capture on the server.
If the DNS query is received and the server doesn't reply, please check if there is any query logged in the DNS debug log. If there is nothing logged, it means that the DNS server doesn't receive the query, please check if the DNS packet is blocked by something.
If the DNS query is received and the server replies, please check the network setting.
Besides, due to both of the two NICs don't have a gateway, have you added the proper static routes?
Best Regards.

Making a family sharing calendar public

I am trying to sync my new Family Sharing iCloud calendar with Google Calendar, and am unable to do so. I've been able to make my OTHER iCloud calendars sync by creating "public" links, and then using icaltogcal.com to make the links readable by Google Calendar. however, iCloud does not allow making the "Family" calendar public, only allows sharing via email address.
Am I going to have to abandon iCloud / Family Sharing for calendar usage, and rely solely on Google Calendar?

Hello Jacqui L Davies,
It sounds like you may need to change the settings for access to the Family Calendar. See if this section of the iPad User Guide applies to your situation:
Share iCloud calendars - iPad User Guide
http://help.apple.com/ipad/8/#/iPadc2a14a22
Share iCloud calendars
With Family Sharing, a calendar shared with all the members of your family is created automatically. See Family Sharing. You can also share an iCloud calendar with other iCloud users. When you share a calendar, others can see it, and you can let them add or change events. You can also share a read-only version that anyone can view.
Create an iCloud calendar. Tap Calendars, tap Edit, then tap Add Calendar in the iCloud section.
Share an iCloud calendar. Tap Calendars, tap Edit, then tap the iCloud calendar you want to share. Tap Add Person, then enter a name, or tap to browse your Contacts. Those you invite receive an email invitation to join the calendar, but they need an iCloud account in order to accept.
Change a person’s access to a shared calendar. Tap Calendars, tap Edit, tap the shared calendar, then tap the person. You can turn off their ability to edit the calendar, resend the invitation to join the calendar, or stop sharing the calendar with them.
Turn off notifications for shared calendars. When someone modifies a shared calendar, you’re notified of the change. To turn off notifications for shared calendars, go to Settings > Mail, Contacts, Calendars > Shared Calendar Alerts.
Share a read-only calendar with anyone. Tap Calendars, tap Edit, then tap the iCloud calendar you want to share. Turn on Public Calendar, then tap Share Link to copy or send the URL for your calendar. Anyone can use the URL to subscribe to the calendar using a compatible app.
Hope that helps ...

Making section of private site publicly visible

I have one section of an otherwise private iTunes U site that I would like to make visible, because it contains content from our university's radio station and student newspaper that they would like the public to be able to see.
I have set the All and Unauthenticated credentials to have download access on the main site welcome page, and then made sure that this only cascades down to that section and the course pages it contains. I have overridden this download access for All and Unauthenticated to give them no access to other sections, divisions, and course pages.
I am able to link directly to the course pages for the radio station and the newspaper and view/download content without needing to log in. However, when I access the main site welcome page without logging in, all that shows up is my header graphic and my links boxes. The section that I am trying to make public and the course pages it contains do not show up on the main site page as I think they should.
Can anyone help?

Redirect public DNS record to url

I am looking for advise as to what to do. I want to take my mail.xxxx.com record and point it to a url such as http://something.some.thing/mail
Is this possible to do? It seems like I should be able to do this somehow.
cheers

Sounds like you're getting a little confused. There is no correlation between a DNS host entry and a URL - you can't have a DNS record that points to 'http://something.somewhere.net/mail'.
What you can do is point your DNS entry to an IP address of a server that's running a web server. Now when users enter your hostname in a web browser they'll connect to this server.
You then configure the web server to automatically redirect to /mail if that's where you want the user to end up. The process would be something like:
DNS: mail.somewhere.net -> x.x.x.x
Server x.x.x.x runs a web server.
Web server redirect / requests to /mail
Now a user can enter http://mail.somewhere.net/ and end up talking to http://mail.somewhere.net/mail/ thanks to the web server, not the DNS server.
To do this you'd add a line like:
Redirect / /mail/
to your web site configuration.

Making mini DVD's

Does anyone know if DVDSP can create mini DVD's?
I have a client that would love to be able to distribute their project on mini DVD's.
Any help would be greatly appreciated, thanks.
2GHz dual G5 (rev2) Mac OS X (10.4.8)

Hi:
AFAIK a Mini DVD is just a diferent media, not a different DVD Video standard. Then, your DVDSP project will be able to be burn on a Mini DVD as far your content fits on its capacity.
The only problem could be you (or your customer) could reduce the audience because some computers could not accept MiniDVD/CD discs . . . for example some slot loading Macs.
I'm sure some other ideas will arrive here !
Hope it helps.
