Do I need to run local DNS server for NAT/DHCP to work?

Hello,
I'm coming across all kinds of explanations how to set up a server for public access, having a static IP and a pointed domain, but I have a dynamic public IP and don't need the server to be accessible through a domain name. I just want all the computers in my office to connect to the web over 1 cable connection. I've used Gateway Setup Assistant to set up NAT and DHCP and DNS and what not, but it didn't work out of the box. After some bootpd.plist fixes I now have DHCP working, it's handing out IP addresses, but all LAN connected machines cannot get onto the web, only the server can.
What am I doing wrong? Should I configure my DNS server differently? Or should it not be on at all, couldn't the local machines use my ISP's DNS servers?
Currently DNS is configured like this:
Settings are:
accept recursive queries from the following networks: localnets
forwarder IP addresses: (empty)
Zones are:
private. primary zone
134.23.24.in-addr.arpa. reverse zone

Though still a valid question for others I guess, I got my DNS working. The network preferences didn't have external DNS servers configured for the local network interface.

My e4200 as a local dns server

Hi,
i'm trying to find out whether my e4200 has the possibility to be a local DNS server and if so, how I can configure it. As it is right out of the box, i cant ping any of my local machines on DNS.
Any ideas?
thanks!

If you are using windows pc's
this will for the most part take of the local name resolution issues
there are a few exceptions, which are mostly related to web browsers
in that IE, Firefox, and others all deal with name resolution a little differently
some need http://localclientname to work
while others will will work with just the localclientname
and the chaos of that is different amongst different versions of browsers
but as far as local name resolution goes, the following works well
On the router config page under the Setup tab for basic setup
Internet Setup has a setting for domain name
Domain Name: local
DHCP Server Setting has a setting for static dns servers
Static DNS 1: 192.100.1.1
doing the above will put all of the local dhcp clients in the .local dns zone
that the windows world can deal with for local name resolution
as far as other devices etc, its hit miss, but this does work me very well
I can even get name resolution to my network printer via web browser or via an os explorer ping etc.

Dns server for specific domain

Is there a way to define a dns server for a specific domain?
I'm setting up a develop machine with an amp stack and i want to redirect all urls with a specific domain (i.e. project.dev) to 127.0.0.1.
I've done this on OSX with dnsmasq configured in this way:
# dnsmasq.conf
address=/.dev/127.0.0.1
listen-address=127.0.0.1
port=35353
and adding a dev file in /etc/resolver with this content
# /etc/resolver/dev
nameserver 127.0.0.1
port 35353
but this in arclinux with dhcpd doesn't work.
I've tested dnsmasq with
dig [email protected] -p 35353
and it works (the address returned is 127.0.0.1) so the problem is the resolver.
I've also tried either put into /etc/resov.conf.head this:
# /etc/resolv.conf.head
nameserver 127.0.0.1
port 35353
and configure dnsmasq with the default 53 port without luck.
This is my /etc/resolv.conf
# /etc/resolv.conf
nameserver 127.0.0.1
nameserver 192.168.0.1

On linux you should simply run all dns request through one nameserver that forwards everything it doesn't understand. [Edit: You can do that with dnsmasq.] Another simple way to create a local developer zone would be to use wildcard_dns_proxy instead.

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.

Proper Configuration of DNS server for our new branch office

Hi All,
Our new office will setup a new branch office with a routed network link to our HO. In HO, we have 2 domain controllers configured as AD and DNS just for fail over scenarios.
How will we configure the DNS server of our 3rd domain controller which we will placed in the new branch office. What would be the proper settings of DNS server integrated to AD to work well especially to have a successful replication and communication to
the 2 DC's located in HO?

Hi,
If you have multiple DC's in that site i would recommend using any of the partner DC's IP addresses as preferred one and secondary DNS IP to pointing to itself. Dont use loopback addresses configure it with actual IP addresses.
If you have only one server in branch office point itself as the primary DNS and HO DC as secondary and tertiary.
Make sure that all clients in your branch site are pointing to the branch DC as primary DNS server.

GSS as primary DNS Server for Intranet

Hi,
Can the GSS be used as a as primary DNS server for Intranet? An additional DNS server can be configured to answer the unknown Records like MX by GSS.
if it can be configured, I would be thankful if anyone shares with me the brief configuration steps Apart from configuring Answers, answer groups, domain lists, source address lists, DNS rules.

Yeah I'd certainly recommend against it! So essentially the client machines are unable to update or query dynamic AD related DNS records since they're not pointing to the DNS servers actually used by your AD server(s). I could well imagine that causing
issues, and meaning that some AD functionality won't work correctly.
I know you can directly integrate BIND with AD, eg so that the BIND servers are the ones used by AD, though I haven't tried it, but this seems to be neither.
I can't find any articles relating to your exact situation, presumably no one else has tried to use such a mixed and disjoined setup. I'd focus on looking for articles relating to why you shouldn't point your users at a router (most commonly in small setups
on ADSL) for the DNS rather than directing them to the server for DNS and then having that query the router for external results. It's a more common scenario and you're more likely to find articles relating to it.
One article you might find useful is
http://msmvps.com/blogs/acefekay/archive/2009/08/17/ad-and-its-reliance-on-dns.aspx which talks in terms of using your ISP's DNS servers on the client machines, but in your situation it sounds like the BIND servers are essentially providing an equivalent
setup.

Do I have to locally host my DNS Server to have iCal Services work?

I have my registrar handling my DNS hosting and have set up an A record for what I'm putting into my "Host Name" field in the iCal Service setting. Is this correct? The error dialog that pops up is:
"No virtual host found for iCal service
More information about configuring the iCal Service and connecting this server to a directory server can be found in the Help menu."
The Help menu is useless. Where do I set up the "virtual host"? The only other place I've been setting up virtual hosts is in the Mail service. Do they overlap?
Oh, and when I try to enable calendaring in WGW, the check doesn't stay enabled. Any thoughts there?

Hi
A hostname or Fully Qualified Domain Name or FQDN (which I'm guessing you have heard of before?) generally looks something like this:
myservername,mydomain.com
You could substitute myservername for something simple like server or ns1 or xserve or osxserver. It can be anything you like. Clearly mydomain is whatever domain name you chose or have. This could be your real world domain or if you are only concerned with providing an internal service then a fictitious one will do. The .com bit can be anything you like. It does not have to be a real world top level domain (TLD). It too can be fictitious. Lots of people use .internal, .lan, .private even .earth or the town or city name of your location. You can even use .local if you like although I would steer clear of this as it can cause problems for the unwary.
Why give yourself problems when there is no need to? The point is if you use something fictitious it just has to look like a real world domain. As you can see if you decided that you only want this to be a private server behind NAT/Firewall then your hostname could look something like this:
server.newyork.here
I'm using New York as an example. You can also regard the above as the fqdn of your server. In the DNS Service you can add CNAMES or Aliases for specific services you are interested in. Something like intranet or www for the Web Service and possibly ical or cal or calendar for the iCal Service. Your server would then resolve its IP Address to all of those names in addition to its server name. Something like this:
intranet.newyork.here
calendar.newyork.here
And so on. You can 'push' this information out to your client computers using the Server's DHCP Service. Client computers would then be using the Server to resolve their DNS as well. If all of their services are coming from the server then that would make logical sense. At the moment iCal works best if client computers are bound to the Open Directory Master (your server) and are using it for their DNS. Proper working of Open Directory absolutely requires internal DNS running somewhere. Either on the server itself or on another server elsewhere.
I'm not an expert by any means and this is all simply put but you should be getting an idea of what is required by now?
I posted something some time ago that 'walks' through how to set up from scratch your server, DNS and OD simply and concisely. If you are at an early stage or purely testing then perhaps you can give it a go and see if it works for you?

I need help with proper DNS setup for 10.5.8 Server

I'm administering a 10.5.8 server that I sold and setup about a year ago. I'm experiencing issues with getting iCal server to be happy. All of the clients are running 10.5.8, but I'm running 10.6.1. I've heard from others that connecting iCal in 10.6 to a 10.5 iCal Server should be no problem.
I'm beginning to think that I have DNS issues. Probably because I'm not and never have been 100% certain how to set it up completely correctly. I used to be able to get Kerberos tickets, but now I can't. With the new "Ticket Viewer" in 10.6, it asks for two bits of information. First is "Identity" where I'm guessing I should put [email protected] and then password. When I do this I get an alert dialog that says "Kerberos Error -- cannot resolve network address for KDC in realm example.com"
The server is a Mac Pro tower with two Ethernet ports. En2 is connected directly to the Internet and has a static IP with a domain name assigned to it. We'll call it "example.com" for the purposes of the discussion. The En1 is connected to the network switch and has a static LAN IP of 192.168.1.250. All clients inside and outside are able to reach the server via domain name for WWW & AFP, no problem.
nslookup on the static IP address returns "example.com" and nslookup on "example.com" returns the correct static IP address. Open Directory is running and happy including Kerberos. The LDAP search base is "dc=example,dc=com". The LDAP search base is a concept I haven't quite grasped, so I'm just going to assume it's correct.
The domain name is hosted outside by a service provider that forwards all "example.com" requests to the server with the exception of mail.
In DNS, I have three "sections" that look like this:
Name Type Value
1.168.192.in-addr.arpa. Reverse Zone -
192.168.1.250 Reverse Mapping example.com.
000.000.00.in-addr.arpa. Reverse Zone -
000.000.000.000 Reverse Mapping example.com.
com. Primary Zone -
mail.example.com. Alias mail.our-email-isp.com.
example.com. Machine Multiple values
www.example.com. Machine Multiple values
NOTE: the zeros aren't actually zeros, they are the static IP assigned to the server/domain
When I select the top element "1.168.192.in-addr.arpa." down below "Allows zone transfer" is NOT checked. Nameservers shows the zone as "1.168.192.in-addr.arpa." and the Nameserver Hostname as "ns.example.com."
When I select the next line down "192.168.1.250", Resolve 192.168.1.250 to: example.com.
When I select the "000.000.00.in-addr.arpa." element, it has the same settings -- nameservers "000.000.00.in-addr.arpa." and "ns.example.com."
When I select the next line down (our static IP), Resolve 000.000.000.000 to: example.com.
When I select "com." the admin email is populated with a valid email address, Allows zone transfer is NOT checked. In nameservers, Zone is "com." and Nameserver Hostname is "example.com." The mail exchangers are mail2.our-email-isp.com. priority 10 and mail.our-email-isp.com. and priority 20.
When I select the machine "example.com." it shows both the real-world static IP and the 192.168.1.250, same with "www.example.com.".
Am I doing something wrong with this setup? Should "com." be the primary zone or should that be "example.com." ???
I've been thinking about getting rid of the DNS entry for the 192.168.1.250 address altogether, but will the clients in the office suffer performance issues??? I do not think that the client workstations are configured to get DNS from the server anyway. Should the "www.example.com." record be a Machine record or should it be an alias record?
Any help you have to offer is greatly appreciated! Thanks!
In the meantime, I'm going to look around and see if I can understand "Allows zone transfer" and LDAP Search base a bit better.

Okay, I found a lovely article at the following address which I think helps me to clarify what I'm doing wrong. Despite that, I'd still like to have any feedback you have to offer.
http://www.makemacwork.com/configure-internal-dns-1.htm
Also, when editing DNS entries, Server Admin likes to set the nameserver to "ns." -- whatever your domain is. Should I be overriding that and if so, replace it with what?

How many DNS record need to create in Internal & external DNS server for exchange?

Hi friends,
I recently installed Exchange Server 2010 in my organization for testing purpose and I've register a pubic ip too for exchange server on godaddy.com. How many
internal & External DNS records reqired to configure on external & Internal dns server so my all feature like Auto-discover, Activ -sync,& webmail start working perfectly.
It's my first time configuring exchange for a organization.
Thanks & Regards,
Pradeep Chaugule

Hi,
Just as what ManU Philip said, you need to create
Autodiscovery.domaincom and mail.domain.com for external dns server.
Generally, you configure your Exchange Servers as DNS clients of your internal DNS server.

Help... I need help to install a server for my form to run on web

Hi there,
I installed a New server with Windows 2003.
I have some oracle forms developed using 6i, I don't mind to convert them later.
What other oracle 10g software I need to install to have my oracle forms and reports to run on web?
I tried to install in this sequence but not working:-
1- windows 2003
2- IIS
3- Oracle Developer Suite
Then I removed IIS and installed the Oracle SOA Application server also still cannot.
What did I do wrong or what should I install (I meant by sequence?)
Please advise.
Thank you

Why installing IIS o_O?
For Installing a developer Machine just install Oracle Developer suite; for testing your forms you use OC4J ("start OC4J instance" in start menu), and you can run your forms in web; no need for a aditional webserver (don't believe there's an OC4J connector for IIS available; and if so I wouldn't use it either ;-))
For Installing a server for "productional" use install Oracle Application Server (available on otn) which comes with an Apache as webserver and all the other needful things for runnung forms on the web.
For configuring both of them just take a look at the documentations on http://otn.oracle.com

Install 11gr2 RAC, dose all IP needs to go in DNS server or just 3 scan ip

Hello,
I am bulding a brand new 2 node RAC cluster (11gR2). But i know this new version has some big changes with the scan. My question is, do all the IP needs to be in a DNS server or just the 3 IP related to the scan ??
So do i need to put in 2 public, 2 private, 2 VIP, 3 scan ip (all 9 of them) in the DNS or just the 3 scan ip ???

it depends. If you decide to use GNS then no but it you want to do manual configuration of the oracle network portion then yes. (Personally I would suggest do so just as a fallback but that's just me).
the following from the install guide explains it best:
1.2.4 Overview of Network Connection Requirements
The following is an overview of network configuration requirements for Grid Naming Service (GNS) in a Grid Plug and Play configuration, and manual network configuration. Network administrators and system administrators can refer to the Preinstallation chapter in Oracle Grid Infrastructure Installation Guide for your platform for detailed configuration information.
The network configuration for Oracle Clusterware and Oracle RAC requires several addresses. The following is a list of those addresses:
GNS virtual IP address (GNS installations only): A static IP address configured in the GNS. The GNS virtual IP listener forwards queries to nodes in the subdomain on the cluster managed by GNS.
Within the subdomain, the GNS uses multicast Domain Name Service (mDNS) to enable the cluster to map hostnames and IP addresses dynamically as nodes are added and removed from the cluster, without requiring additional host configuration in the DNS.
To enable GNS, you must have your network administrator provide a set of IP addresses for a subdomain assigned to the cluster (for example, grid.example.com), and forward DNS requests for that subdomain to the GNS virtual IP address for the cluster, which GNS will serve.
Single Client Access Name (SCAN): A domain name that resolves to all the addresses allocated for the SCAN. Oracle recommends that you allocate three addresses to the SCAN. During Oracle Grid Infrastructure installation, listeners are created for each of the SCAN addresses, and Oracle Clusterware controls which server responds to a SCAN address request.
For high availability, you should provide at least three IP addresses in the DNS to use for SCAN mapping for high availability. A SCAN domain name must be unique within your corporate network.
Virtual IP address: A public internet protocol (IP) address for each node, to be used as the Virtual IP address (VIP) for client connections. If a node fails, then Oracle Clusterware fails over the VIP address to an available node.
During installation, if you do not use Grid Naming Service (which provides the VIP automatically), you provide VIP addresses. The VIP for each node is associated with the same interface name on every node that is part of your cluster. If you have a domain name server (DNS), then your network administrator should register the host names for the VIP with the DNS, so that it is resolvable from any client, as well as the cluster nodes. The VIP should not be in use at the time of the installation, because this is an IP address that Oracle Clusterware manages.
Public IP address: A public host name address for each node, assigned by GNS, or assigned by the system administrator during initial system configuration for manual configurations. The public IP address name must be resolvable to the hostname. Register both the public IP and the VIP address with the DNS. If you do not have a DNS, then you must make sure that both public IP addresses are in the node /etc/hosts file (for all cluster nodes).
Private IP address: A private IP address for each node to serve as the private interconnect address, dedicated exclusively to internode cluster communication. GNS configures the address automatically. If you select manual configuration, then you must ensure that the following is true for each private IP address:
o
It must be separate from the public network
o
It must be accessible on the same network interface on each node
o
It must be connected to a network switch between the nodes for the private network; crosscable interconnects are not supported
The private interconnect is used for internode communication by both Oracle Clusterware and Oracle RAC. If you use manual configuration, then the private IP address must be available in each node's /etc/hosts file. Oracle recommends that it is configured on a dedicated switch (or switches) that are not connected to anything other than the nodes in the same cluster.
Note:
All host names must conform to the RFC 952 standard, which permits alphanumeric characters. Host names using underscores ("_") are not allowed.
