Clients lose only DNS server. HELP!

Hello,
I've encountered a problem these days with my dns server. My clients gets a 192.168.0.1 dns server, instead of the server dhcp/dns 192.168.74.3. I verified the dhcp/dns server and everything seems to be ok. This happens all random. When I disable/enable
the LAN or use the ipconfig /release /renew command the everything works fine for half an hour or so then it's changed back to that fake dns. Any advice?
Thanks!

Hi,
When the DNS server changes to 192.168.0.1, does ipconfig /all tell you that the IP address configuration currently in use is assigned by DHCP? If so, then what is the DHCP server that assigned this configuration?
For example below the DHCP server is 192.168.1.1:
Ethernet adapter vEthernet (External Network):
   Connection-specific DNS Suffix . :

If you can identify the DHCP server that is providing this DNS server to you, then you can shut it down. This might be a rogue DHCP server on the network, probably using itself as a DNS server.

DNS server Help

I already have a dns server in window platform for window lab. I am planning to create a open directory for mac lab consisting of 20 mac pro. Do I have to need a separate dns server in mac server or I can use the dns server from windows.
I really appreciate any help.

Successfully running your own Open Directory server requires working DNS. However, there's no requirement that this DNS server be running on your open directory server.
Therefore you're welcome to use your existing DNS server, as long as it has all the associated forward and reverse records for your server you should be OK.

DNS Server Having Intermittent Issues with Open Directory

I work for a school and we're undertaking the large task of moving from Xserves running 10.6.8 to Mac Minis running 10.9. I have a lot of experience with OS X Server (I held ACSA up until they ditched it, and ACTC through the current OS) but I've hit a fairly large snag in configuring our DNS server. We currently run DNS via an AD server that is being retired at the end of the summer, so this is the first time our DNS will be Mac-based. That said, our network is ridiculously simple as we are a very small school. For the most part it's a flat network using the same IP range for our wired and wireless internal clients (we do have a vlan for guests but that's through Aerohive). I configured the DNS by hand, recreating the entries in our AD server (there were only about a dozen) and then adding in things that should have been there in the first place (e.g. printers and some other devices with static IPs that I'd like FQDNs for). Everything seemed to be working fine...until trying to log into Open Directory accounts.
For some background, the DNS server running 10.9 was the first server we upgraded and it was a completely clean install. We run DHCP on another Mac Server currently running 10.6.8 and it does have the proper OD server listed. All DNS entries for the OD server match our current DNS server. The issue is that it's taking some users 5-6 tries to log in with their network accounts. The errors they receive range from the login window shaking to it stating the user cannot log in at this time. This seems to be worse on client machines running 10.9. but it's appearing on machines running 10.6.8-10.9.3.
In my troubleshooting, I found that if I log in as a local user to one of those machines and do a dig for the OD server the results vary, this is where it gets weird. For example, if I dig ourodserver.ourdomain.org it will sometimes return host not found or it will sometimes resolve. If I ping the same thing it will sometimes work (even after stating it cannot resolve the host) and it will sometimes fail. If I then try a dig for the .local (e.g. ourodserver.local) it also yields the same varied results. However, on every machine that I've tested if I then open a Finder window and navigate to the server via the "Shared" menu and connect I have no trouble connecting and then magically my digs and pings in terminal work. If I revert DNS back to point to our old Windows server the issue goes away. I have meticulously combed through that server many many times now and am not seeing any missed entries. Any idea what could be causing this?

You must have a working DNS service, and the server's hostname must match its fully-qualified domain name. To confirm, select the server by name in the sidebar of the Server application window, then select the Overview tab. Click the Edit button on the Host Name line. On the Accessing your Server sheet, Domain Name should be selected. Change the Host Name, if necessary. The server must have at least a three-level name (e.g. "server.yourdomain.com"), and the name must not be in the ".local" top-level domain, which is reserved for Bonjour.
The primary DNS server used by the server must be 127.0.0.1 (that is, itself) unless you're using another server for internal DNS. The only DNS server set on the clients should be the internal one, which they should get from DHCP if applicable.

Mac mini server networking and DNS setup help

Thanks in advance to anyone who can help me with this. I'm working at a small business where I'm the only guy with any IT experience at all, but I'm new to Macs and OS X (<1 year) and being a server admin so please bear with me.
We just bought a Mac mini server as we are expanding from a bunch of workstations and Google Docs. I've just gone through the installation process, but nothing else is on the server, no user data at all, so if the answer is to reinstall from scratch, I can do it.
We'd like the mini to be a file server, print server as well as the gateway for the internet. I realize we could stick to our router and have the server as another node in the network, but we also got a Time Capsule for backing up the server and will locate it in another room to be another wireless access point there.
When going through Server Assistant, I didn't really know what to name the machine so I used corp-Server.local for the Current Hostname and corpserver.private for the DNS Hostname (though i actually use a 3-letter company acronym instead of "corp").
However, i realized after setup we'd want to access the server externally by name, so I changed the DNS hostname to server.companyname.com in the Zones tab of the DNS section of Server Admin (edited primary zone name, changed Nameservers entry for both primary and reverse zone).
I don't know what else I need to do though because there are loads of instances where corpserver.private still shows up, like in the Open Directory section of Server Admin (which btw always hangs when I open it) and the Contact Info of users (eg. user email is [email protected]). I also had trouble earlier using Server Preferences and Server Admin either not connecting or not recognizing my login, but that seems to have abated.
I guess my problem is, where else do I change the DNS hostname? Or do I have to change the DNS hostname back to corpserver.private (in Server Admin)? That way, I think at least everything will be consistent, but would I be able to still configure it somehow so that externally, we could access the server by the server.companyname.com URL?
Also, can the mini be a wireless router for the office? As mentioned before, we want to cut the existing wireless router out and use the mini instead (and use the Time Capsule as a wireless bridge).

So the ISP<->router connection can have a dynamic IP address, but the router<->server one should be static? I guess that means I have to set the IP address in the router. I hope I can get access to it. I don't suppose it matters which one I set first?
An IP router does not assign addresses.
A DHCP server does assign IP addresses upon receipt of a DHCP request from a client.
Some routers (and many firewall routers) do include a DHCP server.
A box with a static IP address does not need to send a DHCP request; it has a static address.
You'll need to ensure that the IP address pool within the DHCP server does not overlap the addresses that are manually assigned to your local hosts; the static IP addresses on your LAN.
[Here is an overview of the pieces involved here, and some of the typical terminology|http://labs.hoffmanlabs.com/node/275].
I hate to belabour the point, but I just want to clarify: in my setup where ISP<->router<->server<->clients, where the server is the only machine connected to the router, which one should be the local DNS server? The server, right? So if the DNS server is turned on in the router, I should turn it off? Or do I need both (ie. router for its LAN (to server), and server for its LAN (to clients))?
So to confirm, the configuration includes (probably) a modem, a router (firewall) and a router (Mac), and then the rest of the (local) show? That is not the simplest configuration, and it's Particularly given that Mac boxes make expensive and slow routers.
The usual configuration is ISP>firewall>LAN and the LAN is usually built from WiFi, wired connections and switches. Within one subnet (which is typical) any host inside your firewall is connected on the LAN, and can communicate (directly) with any other LAN client. The firewall is configured as the gateway; that's the default route for outbound connections.
One more thing that's bugging me: I still don't understand why I couldn't connect to the internet when I plugged in the Ethernet cable from server to router. Even if I was using DHCP to get a dynamically allocated IP, shouldn't it still have worked? I'm worried that I'm going to set up everything as it should be but the connection still won't work.
That's likely because you're trying to use the Mac as a router, and that takes specific configuration steps. It's easier to have ISP>firewall>LAN, and have the Mac OS X Server box and the rest of the stuff as peers on your LAN. If you really want to use the Mac as an IP router, look around for setting up static routes on Mac; there are postings around for that.
If your data is more valuable and your security preferences and requirements are higher, then you may want a firewall with a DMZ, and put your web-facing boxes over in the DMZ. If you're serving stuff to the web or a mail server or such, it's possible to get breached, and a breach means folks can potentially get further into your LAN. With a DMZ, they're somewhat more isolated from your LAN.

Instant Client with SQL Server - HELP!!

G'day all...
My goal is to connect to a server using Oracle Database version 8.1.7.4, from a server which does not have either Oracle Database or the full Oracle Client, preferrably using SQL Server DTS packages.
With that said, I have installed instant client basic and instant client ODBC suppliment on our first development server using the instructions at the following link without any difficulties, although I do admit that I only have a tnsnames.ora file and not a sqlnet.ora file:
http://www.oracle.com/technology/tech/oci/instantclient/instantclient.html
The trouble is, when I attempt to deploy it on any of our other servers it fails. When I attempt to connect using Microsoft ODBC Driver for Oracle in a DTS package in SQL Server I get the following error message:
HResult of 0x8004005 (-2147467259) returned Unexpected error occurred. An error result was returned without an error message.
(Note: This is seen on all other servers I've tried this on except for the first one).
I have also tried setting up a System ODBC connection using the Instant Client driver but it returned this error message:
Unable to connect
SQLState=S1000
[Oracle][ODBC][Ora]ORA-12705: invalid or unknown NLS parameter value specified
In desperation I have also tried installing the Oracle RDB Driver and the Oracle 8.1.7.8.1.0 ODBC driver. Both appear to install successfully yet nothing seems to work.
As far as I can tell,l these are the differences between the first server and the other servers:
- First server is MS SQL Server 2000 version: 8.00.760, rest are 8.00.818
- First server is running MS SQL Server Analysis services, rest are not
- First server is MS Windows 2000 Advanced Server, rest are MS Windows 2000 Server
So my first question: Does anyone know if the Instant Client tool works with SQL Server version: 8.00.818?
My second question: Can anyone else suggest something that I haven't tried yet, short of installing the Full Oracle Client on this server? Not that I'm opposed to doing that, it's just that it's a last resort idea as of now...
Please help - need to roll this into production soon...

Kent, I see that many others have reported that error (doing
a google search), but I see no ready answers. I saw something that
reminded me of a connection string value that I've seen answer some
problems. May be worth a shot for you: try adding this string to
the connection string (in "advanced options") for your datasource:
AuthenticationMethod=Type2
If it doesn't solve it, remove it. But keep it handy in case
it ever may help with some other problem.
Here's one other possible answer for you:

Dns server and client in java

Hello!
Im trying to code a dns server and client in java.
It`s supposed to be a very simple one. The server should just resolve the query, started from the client.
Where can I find any code samples? It would really help me to get started.
Thank you very much!

Do you have some code ?

VPN Client is not adding DNS server IP addresses

Hello all,
I'm new to the forum and could use a little help.
I use a CheckPoint VPN-1 to connect to my work network. The problem that I have is that I need to add two name servers to access the various sites and applications at work. I have not been able to find a way to do this within VPN-1. I found a listing in for DNS servers in the user.C file but as soon as I edit it and add them (and the edit back up so that it doesn't just over write my changes) it says the files are corrupt and reloads it from the network. What a pain.
Right now I am manually adding the IP address to my DNS list when I connect, then cursing when I use a browser after dosconneting, then removing them manually. If it were not for the fact that network access is dramatically slower when I'm not using the VPN and have the additional name servers listed, I would just leave them there and be done with it. But network performance seems to suffer dramatically when they are listed and the VPN is not active. As soon as I remove them, performance returns to normal.
What I need is a way to add two DNS Server IP Address when VPN-1 connects to the network and remove them when I shut down the VPN. I personally don't care if it's a separate utility, Automator Script, Apple Script, or even a different VPN client, as long as it will connect to a CheckPoint FW.
I have started looking at other clients. I have looked at PSecuritas, it connected to the FW fine, had a place to add the DNS IPs but did not add them correctly either. I also looked briefly at VPN Tracker, for $120 .... I don't think so ..... it's a hassle, not broken.
Any help would be appreciated.

How do I use internet sharing from my MacBook Pro (static IP, only one DNS server) to my iPod Touch?

Hey,
   I'm connecting to the net using an Ethernet cable to my MacBook with the following network settings.
IP Address: 192.168.y.{0-250}
Subnet Mask: 255.255.255.0
Router: 192.168.y.x (where 'y' is the same number as in the IP address)
DNS Server: 192.168.99.3
Apologies if I'm being unclear; not sure how much information it's OK to share publicly.
   I then turn on Airport and Internet Sharing, and look for my wireless network with my 4th generation iPod Touch. However, the network appears erratically. I sometimes have to wait for a minute or two and keep refreshing before it appears on my iTouch. When I try to connect it just says 'Failed to connect to the network'.
   I've followed all the steps in this article with several variations to no avail.
http://lightyearsoftware.com/2010/06/how-to-set-up-internet-sharing-on-mac-os-x/
   Can anyone suggest a solution? Any help would be greatly appreciated. I've been banging my head against this for days.

On the advice of a friend I installed and ran a program on my MacBook called 'IPSecuritas'. This has stopped my wireless network from appearing and disappearing, but I still can't connect. Would really appreciate some help with this.

Can't override DNS Server settings - can only append!

See this thread for a similar question:
http://discussions.apple.com/thread.jspa?messageID=3555096
I have also filed this with Apple (Problem ID 5159216). Here is the text of the report (with a few bits removed - not crucial to understanding the report).
If anyone has suggestions/clues to resolve, please advise. Thanks!
Summary:
This problem concerns AirPort Extreme (802.11n) at revision 7.1. I will summarize with a comparison between AirPort and MacOS X.
MacOS X and Airport Extreme (referred herein as "AE") both permit editing of DNS server settings whether in DHCP or Manual mode.
When MacOS X DNS server settings are set manually by the end-user, the new server IPs are used (good). When AE's DNS server settings are overridden by the end-user, the new server IPs are NOT used (not good)! Rather, the DHCP-supplied DNS server always pre-empts whatever is given in the AE Configuration UI.
Steps to Reproduce:
1. Using AirPort Extreme (802.11n) at revision 7.1 and MacOS 10.4.9 on a MacBook Pro (Core 2 Duo). The AE has been previously configured for IPv4 using DHCP and the MacBook is successfully connected and resolving domain names through the AE.
2. Visit "Apple Menu > Location > Network Settings" and check the AirPort TCP/IP settings. For purposes of this test, make sure the "DNS Servers" field is EMPTY so MacOS X defaults to the AE's DNS settings, then close System Preferences.
3. Run "AirPort Utility" (the newer version, not "Airport Admin Utility") and configure the AE under test. Pick the "Internet" icon in the toolbar and note the Internet Connection settings.
4. In this test, Configure IPv4 is set to "DHCP" and the DNS Server(s) field contains two DNS IPs assigned by the Internet Service Provider. In my case that's Cablevision's Optimum Online service. You may or may not see IP addresses here, but in my case they are visible.
5. As the DNS Server(s) are editable, and they both show ISP-supplied addresses, they can be changed to whatever alternate IPs you wish. For instance, change them to these alternate DNS IPs from OpenDNS.com: 208.67.222.222 and 208.67.220.220. (You could use any alternate set of IPs but for the purpose of this test use the OpenDNS IPs.) Update the AE and restart.
(For additional reference, http://www.opendns.com/start/airport.php shows instructions for the older AirPort Admin Utility, but the concept is exactly the same.)
6. Normally you shouldn't have to restart the MacBook Pro since we're just using the AE settings, but go ahead and do that just to be consistent with this test.
Expected Results:
Now for the moment of truth! We want to verify that we're using the OpenDNS IPs for our DNS Servers. One nice feature OpenDNS has is automagic redirection for certain domain name typos.
Here's an example. Drop to shell (Applications > Utilities > Terminal) and try this command (excluding the $ prompt, natch):
$ dig craigslist.og
The "og" typo is deliberate. We really want to go to craigslist.org. If you're using the new OpenDNS IPs, you will STILL get an Address (A) record with an IP like so:
;; ANSWER SECTION:
craigslist.og. 0 IN A 208.69.32.130
If you had entered "craigslist.og" in Safari, you would end up at 208.69.32.130 (an OpenDNS server) and then redirected to craigslist.org.
Actual Results:
Alas, that's not what happens! Instead, you get NO IP address, like so:
;; QUESTION SECTION:
;craigslist.og. IN A
This means we're not actually using the OpenDNS IPs. What's happening?
To find out, I spoke with the AirPort support group (Case # xxx-xxx-xx). I learned that, despite being allowed to edit and override the IP addresses provided via DHCP, the AE still uses the DHCP-provided DNS server if available.
Again, the user interface suggests that I'm allowed to override the DHCP-provided DNS IPs as shown in the UI. Even though I can do this, the AirPort will still keep note of any DHCP-provided DNS Server IPs and use those first.
True, I can switch to Manual network settings (and then my own DNS Server IPs take effect). Of course this is problematic when the ISP renews my IP address (which it does from time to time).
Another workaround is to use the "DNS Servers" settings noted in step 2 (above). However this is also problematic if I want to keep my network settings simple. It requires a "Home Network" location and an "Office" location. Still not preferable, but it's a workaround.
Regression:
n/a
Notes:
I would like AirPort's DNS settings to be overridden in the same way OS X allows DNS settings to be overridden. The user interfaces suggest this is possible but it is not. It's only possible in the OS X case. Having the same flexibility on the AirPort would be most welcome.

Afraid of the answer...sheesh...you must be a child. This has nothing to do with masquerading anything. The issue being discussed here is that people want to manually assign a dns server address via the new AEBS, while maintaining DHCP for IP address assignments through their ISP. For example, I would like to have opendns.com take care of all dns addressing at the router level, even though I have "Configure IPv4" set to "Using DHCP". If you do not understand why one would want to use something like opendns.com, please visit their website and enlighten yourself. The fact that the dns server address fields are editable when set to "Using DHCP" leads one to believe that you can manually assign a dns server in this configuration; however, under firmware 7.1.1, you still cannot. The previous iteration of the airport hardware can do it, as can nearly any router you pull off the shelf. In addition, this is something that can easily be done at the individual-computer level in OS X; however, many people would prefer to administer their network at the router level. That is the issue being discussed here. Either you can't read or you are purposely derailing the thread.

How can I determine what dns server the wifi client use within airport

How can I determine what dns server the wifi client use within airport
I want to use dns servers other then the one that airport extreme is using. For example I got the 172.16.1.1 (the default gateway - airport extreme), but I want to use the office dns servers, that are in a 10.x.x.x range.
Is there a possibility?
Thanks and happy eastern

The Airport Extreme uses the DNS servers assigned by the network that it connects to. Is you Airport Extreme on the 10.x.x.x network? if it is then you are already using the 10.x.x.x DNS servers. Check your Airport Extreme with the Airport Utility and you will see in the Internet tab, the DNS servers used. The devices connecting to the Airport Extreme are assigned a DNS address of the Airport Extremes IP, In your case 172.16.1.1 but all DNS searches and resolution are done with the DNS servers you see in the Airport Extreme.
If you want to use some other DNS then you can override in the Airport Extreme which will be used by all devices connecting too the Airport Extreme, Or you can edit the DNS address in each devices wireless settings.

Why doesn't my airport express router issue proper DNS server address to DHCP clients?

I have an Airport express router (version 7.6.4). It was configured to connect to internet via a cable modem, acting as a router with NAT. This means it obtians WAN address from cable modem, and in LAN it assumes IP address 10.0.1.1 as a gateway, and issue IP address to my 4-5 wireless clients (MBA, iPads, PCs) vi DHCP.
However I recently encounter an issue, that the router no longer issues DNS server address obtained from Cable Modem(206.x.x.x) but instead tell every DHCP client to use router ip address (10.0.1.1) as DNS server. I was pretty sure before Dec 2013 it is issueing (206.x.x.x) to all DHCP clients.
Apparently now the Airport express is acting as a DNS server or as a DNS cache. This works sporadically and very often result in long DNS look up or DNS look up failure.
Is this a bug or is it supposed to do so? Any configuration can turn it off so Airport express will issue Cable modem obtained DNS server to DHCP clients?
My network otherwise works fine. for some of the Clients (e.g. one MBA) I configured DNS for it mannually and it's internet is working very smoothly.

But this will be a problem for my ipad and iphone that uses wifi.
These devices either allow full DHCP. If you need to mannually enter DNS server, you will need to turn entire IP configuration to mannual and that will be a problem for me.

How to configure the mac mini to allow the clients to access both partitions...the client will only see the one we are logged into at the server???

if possible??? how do we configure the mac mini to allow the clients to access both partitions...the client will only see the one we are logged into at the server???

You have to explicitly share directories on external/secondary volumes.
Use the Server admin app to configure file sharing, and select which directory/directories on the second drive you want to share, then they'll be available to clients.

Need help regarding Simple Data Client and Simple Data Server VIs

Hi everyone.
I have a simple objective. I just want to test the 2 example VIs, "Simple Data Client" and "Simple Data Server" between 2 computers. I just want to check whether is this working between the 2 computers.
What I have done for now is that I changed the "address", from "localhost" in the "Simple Data Client.vi" to the IP address of the computer running the "Simple Data Server". I runned the "Simple Data Server" VI in one of the computers first followed by the "Simple Data Client" in the other computer. Nothing is received and the client just timed out.
Can anyone please help me troubleshoot and tell me what are the possible problems for this? Are there any wires connections between 2 computers that I am missing or any other configurations I have to make before I can successfully do this?
Thanks.
Regards,
Jonathan

Hi Lee.P.
I understand that. I was just feeling frustrated about the project not working. Sincere apologies from me.
I was wrong about the error number. It is not Error 60. It is Error 59 - The network is down, unreachable, or has been reset.. Yes, I have tried changing the port numbers at the 2 computers when trying to send/receive.
Could anything else be the problem?

EA6500 - using other DNS server only applies to Guest network?

I have an EA6500. I use OpenDNS.org as my DNS server to provide additonal filtering. I have added the Guest network option to separate my network access.
When I change DNS server settings on the EA6500 to those for OpenDNS, I've found they only apply to the Guest network. For the 'regular' network, the DNS server provided by Comcast (my cable provider) is used. I have verified this by connecting various devices to both the regular and Guest networks and checking which DNS server is in use.
I assume this is a bug in the firmware? Or am I doing something wrong? Please advise.

You're welcome
