Testing DNS settings
Hello
Am 99% sure I finally have DNS set up and working correctly on my Snow Leopard server which is using an airport express as a router, which is in turn connected to an ADSL modem in bridge mode.
changeip -checkhostname returns succesful results - nothing to change.
But before I get out the bunting, I want to make 100% - no 110% sure it is working correctly then ban myself from going anywhere near it.
Are there any other checks I can run? How about a test from one of the clients?
Talking of clients - I assume they should have my DNS serving server listed as a dns server in their network preferences?
Many thanks
Andrew
Hi
+"Talking of clients - I assume they should have my DNS serving server listed as a dns server in their network preferences?"+
Assuming you want to use names rather than IP addresses yes. From a client any of the usual command line utilities should do?: host, dig, nslookup or even ping. If your server's hostname is server.domain.com issuing "host server.domain.com" should return server.domain.com has address 123.123.123.123. As we know it's just as important if not more o to query the reverse pointer. Issue host 123.123.123.123 and it should return 123.123.123.123.in-addr.arpa domain name pointer server.domain.com. Issuing host -a domain.com should return records associated with that domain. For example:
host -a microsoft.com
Trying "microsoft.com"

Any of the others should return similar information. For usage consult the manual pages: man host; man nslookup; man dig. Other utilities you could use are scutil and ipconfig. Not forgetting using any of the web browsers or mail specific applications. If they can work using the name and then the address that's a fairly good sign things are OK.
Others may chime in with more?
I only ever issue the changeip -checkhostname command after I've tested DNS Services first. The command itself is not a 'guarantee' that everything is as it should be. I've known some DNS misconfigs that are not necessarily 'caught' by the command.

Dear All,
I need your help in order to resolve issue i got. I have domain controller, and additional domain controller in production and both were working fine untill i restore image on 'Domain Controller' and after that i was not able to browse 'AD'. I checked and
came to know that NETLOGIN service was PAUSED. i fixed that issue but when i went to Additional Domain, that machine was not able to find Dmain. i realise that DNS/LDAP is not working. I run the command "DCDIAG /TEST:DNS" just to check the connetivy,
and found DNS connectivity sissue on Main Domain controller. Please help me with the issue.

DNS settings for Airport Extreme Base Station
This month's MacWorld suggests that changing the DNS setting of the wireless device might increase the speed of the connection. What setting should my Airport Extreme Base Station use.
The Computer system says 10.0.1.1 and it works. When I entered the numbers they suggested I get no connection.
Any suggestions?To change DNS setup on the Airport you need to put in the DNS change on the Internet tab. The Airport will always place itself as the main DNS server to the network clients that connect by DHCP, unless you set the Airport to static IP.. and it will use your ISP DNS server by default.. you can change them if you want. Just type in the new DNS you want to use.
This month's MacWorld suggests that changing the DNS setting of the wireless device might increase the speed of the connection.
http://www.macworld.com/article/2824564/slow-internet-edit-your-dns-settings.htm l
In most cases this is really so minimal as to be insignificant. The airport should cache the regularly used DNS addresses and you can test it by ping to your local DNS or the DNS recommended by MacWorld??.. but honestly a few ms is not going to change the world. To the clients the local network addressing should be still using the Airport as the main DNS.. you can setup manually in each device a different DNS but that can give local network issues as it then has to find local clients by broadcast.
I have a complex dns setup for other reasons.. getting past geolocks..
If I ping my local ISP dns I get

It is very obvious the best ping is the ISP dns because the route path is shorter..
Google is very good but still takes longer and of course dns in another country is much worse. -
Do DNS settings on Airport Extreme propagate to computers
I changed my DNS settings on AE ac. Are these settings supposed to change the settings on every computer on the LAN? If so, what conditions must prevail (e.g. Sys Pred>Network>Advanced must be unlocked)?
I've got clients on Ethernet (6) and WiFi (15). (Oh, this is a home.).
I know what it is like.. my router tells me I have 25 clients at the moment.. it is almost unbelievable in modern homes we have that much IP stuff connected.
I might otherwise have thought it was a business though.
I have double checked just now.. by using a test setup.
This is on a newly reconfigured airport (happens to be gen4 but that is not relevant).
In dhcp Internet mode.. and doing NAT and DHCP the default DNS server passed to the clients is the Apple router itself.
I have done these tests before but it is good to be reminded.
So I have this setup.
And was hoping the DHCP would see the DNS and would pass 8.8.4.4 to the clients. No such luck. Although the AE itself should use 8.8.4.4 and whatever secondary DNS you set.
There is no place to actually set this up DNS server to the clients in the network tab.. it is typical apple minimalist.. DHCP Range being the only possible thing to set..
So when I check the ethernet on the computer I get
So the AE has substituted itself as the main DNS server in the clients. there is no check box to force ISP dns or any other dns values.
This is pretty much default on any router.. that it will use itself as a dns cache instead of directing clients to the internet directly.
The actual dns value used by the AE for lookups will be the one set in the internet tab though.. so it does not need to be set to ISP..
Is that going to work for you.. ??
If not you can force the clients to accept the DNS values via dhcp from the Airport router but only if you use static IP.
Now the rub.. you cannot use static IP on the main router, plugged into a cable router. .you must use DHCP so that will not work.
What you need is a different primary router.. or use one of your express in a different mode. ie doing Static IP.
I have posted the details of the setup a few times.
See Re: airport time capsule keeps disconnecting
I have suggested it for a situation here bridge was unreliable.. but I use this method to assign static IP and special DNS values to clients in my network that require access to US for TV don't you know. -
Hi all,
I have recently got my VPN to work working however I need to get works DNS in. I have configured these in the interface manually and it just ignores the settings and gets standard ones. Is their a way i can either:
1) Assign the DNS of work on my local machine
OR
2) Force it to read this setting?
I have upgraded to the latest firmware and I can ping my router from my work machine, just not the other way round.
Cheers
MatHi… Are you able to ping to the WAN IP address at the office? If not, then you office router does not allow you to ping. You need to check that out with Network Admin at your Office. About the DNS servers, Once your VPN is established, your DNS settings will come into picture and you would then be able to test if the router is able to communicate with this DNS or not. Without the VPN connection, assigning a DNS server would have no effect whatsoever. If you assign a DNS server in the Static DNS settings on the router it should work. If not you can simply assign a DNS server on your PC. In that case you would need to assign one DNS server from ISP and second one be the work DNS.

Can not receive Mac mail -error Outlook cannot find the server. Verify the server information is entered correctly in the Account Settings, and that your DNS settings in the Network pane of System Preferences are correct. Account name: "MacMail"
What are the correct mail account settings and more importantly the correct DNS settings
Thank you for any help you may be able to provide
Cheers
Chris (iMac i7)Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
• Server name: imap.mail.me.com
• SSL Required: Yes
• Port: 993
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
SMTP (outgoing mail server) information:
• Server name: smtp.mail.me.com
• SSL Required: Yes
• Port: 587
• SMTP Authentication Required: Yes
• Username: [email protected] (use your @me.com address from your iCloud account)
• Password: Your iCloud password
Also, you must upgrade your password to meet the new criteria: 8 characters, including upper and lower case and numbers. If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message. Go to http://appleid.apple.com then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.

Hello,
here are few posts (quite some time ago) telling the same trouble:
The VPN Client does *NOT* restore the original DNS settings.
Upon BM3.8.2 Massimo told, that this is a bug in that version of the VPN
client. I face this issue with 3.8.16 and nwclient 4.91.4 with or without
the three currently available hotfixes [1]
Anybody else facing this trouble with the current VPN client release?
May be an older one works better, any experiences?
This trouble is fact even after clean disconnects. But it happens only now and then,
I might need to try it 50 times to see it once.
a followup in CMD boxes with ipconfig /all does show, that the times
to restore the original DNS settings vary from 2 to 30 seconds. Mostly about 5 seconds.
Massimo also told, that a "VPN-down" due to a Win-Shutdown can cause this: So is
there a possibility to trigger a "clean-VPN down" in the Win-shutdown sequence?
As a workaround I packed this line into all users "run" key:
netsh int ip set dns name="LAN-Verbindung" source=dhcp
so at least after a reboot it's corrected.
Any suggestions appreciated,

[VPN Client sometimes doesn't restore DNS settings after disconnecting]
e.g. TID 10096552 is telling such a trouble, that should be fixed with
BM VPN Client 3.8.10

Anybody else who knows about that tool?
After doing some "teachment" to these VPN users the incidents of this
trouble didn't show up as frequent as before. So I assume, that one
reason might be this:
Scenario
VPN connect
PCA connect to host in corporate LAN
PCA full screen *SHOULD* be activated (ALT+ENTER)
working, working, working
shutdown PC in corporate LAN
close VPN tunnel
shutdown local home office PC.
When it was missed to activate PCA fullscreen without noticing this,
then the "remote" start button is not visible.
So instead of shutting down the remote PC, the local PC is shut down.
By that, the local shutdown is killing (not cleanly disconnecting)
the VPN client. When this happened (and I 100% can reproduce this)
after the next boot of the home office PC the VPN connect will *ALWAYS*
fail. After another reboot the VPN connect will succeed again without
any problems.
Is this a known issue? (I cannot find that TID I found before telling
missbehaviour when VPN connects are not disconnected clean. IIRC this
was something fixed in a VPN client version /several/ subversions ago)
Home Office PC = XPSP2+Hotfixes, VPN Client BM 3.8.16, nici from that
one first, now taken from NWClient 4.91.4, no difference.
Regards, Rudi.

How do I change the DNS settings to BC but keep the MX setting for emails?
How do I change the DNS settings to Business Catalyst but keep the MX settings for emails?
I'm basically created anew site using Muse and want to host it on BC and upgraded to the Web basics + to allow for hosting of downloadable pdf's etc.
There are up to 50+ emails address set up on the current set up and I want to just change the NDS settings for the domain to ponit to the new site/hosting an not have to worry about them chaning all the meail settings etc.
Records do I need to change in BC?
Thanks
IainHi,
You shouldn't need to do anything as long as you do not state hosting email with BC. Just ensure to check you DNS in a lookup tool that it's still referencing your external email service.
Otherwise you can set up external email set-up if the option is present.

No DNS settings when using built-in (hardwired) ethernet
Iv'e never had an issue with wireless operation, but now that a wired connection is necessary, I've run into something strange.
When connecting to a LAN with a DHCP source providing IP, router, DNS settings and more, the ibook fails to populate the DNS settings. I've got a valid IP and gateway address but no DNS servers are defined. I can put them in manually, but that would require me to change them each time I connect to a different wired network instead of relying on DHCP to do it's job.
Has anybody else seen this issue?If (as you say "is the case") this is a small, Netgear cable router...then the Netgear will be acting as DNS server. Likely the Netgear is getting a dynamic IP address from ISP, or it's been set with static values the ISP has told the homeowner to enter into the Netgear. Either way, DNS will be provided to Netgear, and the Netgear should be sending the DNS on down to the client computers.
(Do you "see" any DNS server info in the Configuration panel when you're on wireless? If so, what IP address is that DNS server?)
Why does it work wireless, but not cabled?
You really need to go into SystemPreferences>Network>Configure...and tell us what you have configured in the eth0, or built-in Ethernet section.
It might not be a bad idea to reboot the mac after you plug in ethernet...probably not needed, but we don't know enough about your network settings.
You also say you can't access sites by name. Can you hit a website using an IP address in the Safari addressBar? -
Can I connect a PS3 wirelessly via the built-in AirPort card using internet sharing from my ethernet-wired iMac? It works for my Nook e-reader, but the PS3 give a DNS error code 8070102, I've tried alternate DNS settings, but no luck.

Change DNS settings in Solaris 11
Where do I need to go to change the DNS settings on a Solaris 11 server?
I'd like to refer you to the documentation:
http://docs.oracle.com/cd/E23824_01/html/821-1455/dnsref-31.html#dnsref-36
Settings are handled through the SMF repository, using the "svccfg -s network/dns/client" command.
If this does not give you the answer you are looking for, then I recommend viewing the rest of the document.

DNS Settings have Changed with Snow Leopard Update
Before I upgraded to SL, I was able to append a DNS server to the list of servers that my MacBook Pro acquired from the DHCP server. This way, I didn't have to manually edit my DNS settings all the time when I was in the office and wanted to access our lab network by name. Now after the upgrade, I have to remove all manually entered DNS servers before it will use the DNS servers given to it by the DHCP server. Is there a way that I can always append my lab DNS server to the list given to me by DHCP?
Thanks,
JohnI am on or office wireless network which handles the DHCP lease and DNS addressing, but I am an engineer in the office and access the lab often and we have another DNS server in the lab to handle all of the lab network. The Sales folk don't need access to the lab so the DHCP server doesn't give out the lab dns server... I would like to access the lab via name, not IP, so I need the lab DNS server on my list of servers. If I can't append this to the DHCP list, I have to manually add all three every time I am in the office. I am frequently out at customer/vendor sites and use thier wireless, so I get thier DNS list.
Short answer is I need our lab DNS server on the list and frequently move from network to network... I want it to work the way it was before the "upgrade", which wasn't much of an "upgrade" if it breaks this. I want my Leopard back.

Changing Upstream DNS settings
I have an Xserve running OS X Server 10.4.11 and want to change the upstream DNS setting form my ISP's to OpenDNS. The DNS settings in Server Admin don't seem to provide this option and from what I've read, the system Network DNS setting must point to the internal DNS server.
I've read some reports that advocate editing /etc/named.conf but the exsiting file is very sparse and doesn't contain any forwarder entries.
Where the heck are these things set?
- TimThanks Antonio
The Server Admin settings for 10.4 DNS are significantly different than 10.3.9 but the basic info is similar. Everything I read says I must edit the /etc/named.conf file and add the forwarders, but my named.conf file has no forwarder entries yet my DNS server DOES query my ISP's DNS for outside addresses. This must be set somewhere ... but where?
This is all there is in the named.conf file
// Declares control channels to be used by the rndc utility.
// This must be enabled on Mac OS X Server for Server Status to provide valid
// information! (Remove the leading slashes to enable.)
// ** STUFF YOU MIGHT NEED TO ENABLE **
controls {
// unix "/var/run/ndc" perm 0600 owner 0 group 0;
As you can see, there is none of the stuff you would expect, so it must be being done elsewhere. -
Redundant domain controller DNS settings
Hi guys,
We have two domain controllers, both DNS and GC. I am curious as to what the recommended IP DNS settings should be for both DCs? I think it is like this...
DC1
DNS1 - DC2
DNS2 - DC1
DC2
DNS1 - DC1
DNS2 - DC2
Is this the right setup?
Thanks
AaronIs this the right setup?
Yes it is correct. I would go with 127.0.0.1 for 'Alternate DNS server'.
