DNS Configured-Best Practice on Snow Leopard Server?

How many of you configure and run DNS on your Snow Leopard server as a best practice, even if that server is not the primary DNS server on the network, and you are not using Open Directory? Is configuring DNS a best practice if your server has a FQDN name? Does it run better?
I had an Apple engineer once tell me (this is back in the Tiger Server days) that the servers just run better when DNS is configured correctly, even if all you are doing is file sharing. Is there some truth to that?
I'd like to hear from you either way, whether you're an advocate for configuring DNS in such an environment, or if you're not.
Thanks.

Ok, local DNS services (unicast DNS) are typically straightforward to set up, very useful to have, and can be necessary for various modern network services, so I'm unsure why this is even particularly an open question. Which leads me to wonder what other factors might be under consideration here; of what I'm missing.
The Bonjour mDNS stuff is certainly very nice, too. But not everything around supports Bonjour, unfortunately.
As for being authoritative, the self-hosted out-of-the-box DNS server is authoritative for its own zone. That's how DNS works for this stuff.
And as for querying other DNS servers from that local DNS server (or, if you decide to reconfigure it and deploy and start using DNS services on your LAN), then that's how DNS servers work.
And yes, the caching of DNS responses both within the DNS clients and within the local DNS server is typical. This also means that there is need no references to ISP or other DNS servers on your LAN for frequent translations; no other caching servers and no other forwarding servers are required.

Unable to access gateway and DNS via VPN (L2TP) with Snow Leopard Server

Summary:
After rebooting my VPN server, i am able to establish a VPN (L2TP) connection from outside my private network. I am able to connect (ping, SSH, …) the gateway only until the first client disconnects. Then i can perfectly access all the other computers of the private network, but i cannot access the private IP address of the gateway.
Additionally, during my first VPN connection, my DNS server, which is on the same server, is not working properly with VPN. I can access it with the public IP address of my gateway. I can access it from inside my private network. A port scan indicates me that the port 53 is open, but a dig returns me a timeout.
Configuration:
Cluster of 19 Xserve3.1 - Snow Leopard Server 10.6.2
Private network 192.168.1.0/255.255.255.0 -> domain name: cluster
-> 1 controller, which act as a gateway for the cluster private network, with the following services activated:
DHCP, DNS, firewall (allowing all incoming traffic for each groups for test purposes), NAT, VPN, OpenDirectory, web, software update, AFP, NFS and Xgrid controller.
en0: fixed public IP address -> controller.example.com
en1: 192.168.1.254 -> controller.cluster
-> 18 agents with AFP and Xgrid agent activated:
en1: 192.168.1.x -> nodex.cluster with x between 1 and 18
VPN (L2TP) server distributes IP addresses between 192.168.1.201 and 192.168.1.210 (-> vpn1.cluster to vpn10.cluster). Client informations contain the private network DNS server informations (192.168.1.254, search domain: cluster).
_*Detailed problem description:*_
After rebooting the Xserve, my VPN server works fine except for the DNS. My client receives the correct informations:
Configure IPv4: Using PPP
IPv4 address: 192.168.1.201
Subnet Mask:
Router: 192.168.1.254
DNS: 192.168.1.254
Search domain: cluster
From my VPN client, i can ping all the Xserve of my cluster (192.168.1.1 to 18 and 192.168.1.254). If i have a look in Server Admin > Settings > Network, i have three interfaces listed: en0, en1 and ppp0 of family IPv4 with address 192.168.1.254 and DNS name controller.cluster.
The DNS server returns me timeouts when i try to do a dig from my VPN client even if i am able to access it directly from a computer inside or outside my private network.
After i disconnect, i can see in Server Admin that the IP address of my ppp0 interface has switch to my public IP address.
Then i can always establish a VPN (L2TP) connection, but the client receives the following informations:
Configure IPv4: Using PPP
IPv4 address: 192.168.1.202
Subnet Mask:
Router: (Public IP address of my VPN server)
DNS: 192.168.1.254
Search domain: cluster
From my VPN client, i can access all the other computers of my network (192.168.1.1 to 192.168.1.18) but when i ping my gateway (192.168.1.254), it returns me timeouts.
I have two "lazy" solutions to this problem: 1) Configure VPN and DNS servers on two differents Xserve, 2) Put the public IP address of my gateway as DNS server address, but none of these solutions are acceptable for me…
Any help is welcome!!!

I would suggest taking a look at:
server admin:vpn:settings:client information:network route definitions.
as I understand your setup it should be something like
192.168.1.0 255.255.255.0 private.
at least as a start. I just got done troubleshooting a similar issue but via two subnets:

Creating a versatile DNS and redirection service on Snow Leopard Server

For the few of us who use Snow Leopard Server as a main DNS for our small network, the following is a workflow that I would like to share with the board for creating redirection services to not just sites found on the locally hosted apache but also external sites.
+IF you are adding a second domain name, the reverse domain lookup will not appear and you will need to add a Machine/A record with the fully qualified domain "domainname.com." (don't forget the . at the end) into the new zone and it will point to the "server" Machine/A record ip address.+
*DNS Portion* : (ServerAdmin > DNS > Zones >
Add Zone > Primary > Create a fully Qualified Domain name and dns "server" in the Machine / A Record
Create the (add Record > Alias/ CNAME) subdomain pointing to the server.domainname.com e.g. (library)
*Web / Apache Portion :*
Create a new site (ServerAdmin > Web > Sites > Plus button)
With General > host name exactly as spelled in above subdomain in full (library.domainname.com)
Select Web Folder where the site is hosted
If you are creating a redirection, create a folder on the server, add an index.php (with the script below)
Add Alias with the same subdomain as number 2
_PHP script :_
<?php
$location = "http://example.net";
header("Location: ".$location, "301 Moved Permanently");
?>
// Edit the "http://example.net" to which ever e.g. "http://apple.com"
_Alternatively you can also mask the page with :_
<html>
<head>
<title>Same Title As Your Homepage</title>
<script type="text/javascript">
function changeTitle()
if (top.frames['main'].document.title)
top.document.title=top.frames['main'].document.title;
</script>
</head>
<frameset>
<frame name="main" src="http://actual-url.anotherhost.com/page.html"scrolling="auto" target="main" ONLOAD="changeTitle();">
<noframes>
<body>
Place a suitable message here for people with browsers that can't read frames.
</body>
</noframes>
</frameset>

Does Snow Leopard Server iCal Service support iCal Groups?

I have successfully configured iCal Service on Snow Leopard Server 10.6.8v1.1 and have several client Mac system (runing SL 10.6.8v1.1) connected to this service via CalDAV. I can create new calendars and those calendars and any test events propigate to all machines that have this CalDAV account configured. But whenever I try to create a calendar group it always appears as a local calendar group. Is this a feature missing when using iCal Server and CalDAV? Am I doing something wrong?
Thanks

Configure DNS on Snow Leopard Server for Web Hosting

Hi Everyone,
I put together an article on my blog about Snow Leopard DNS setup for web hosting. http://www.mkahn.com/?p=279
I'll be revising it over the next few weeks to make it more informative based around feedback. Let me know if you have any questions or trouble setting up DNS on Snow Leopard Server for web hosting.

Thanks for your replies. I realize I'm not making clear the way this network is configured . Also, the only services running on the Snow Leopard server are (at this time):
dhcpd - in the 10.136.31.x range;
dns - same as before;
planned to add are:
Open Directory (for network logins)
Software update;
Web (only on the 10.136.31.x Ethernet);
mySQL (localhost only - for moodle);
NAT is not set up on the Snow Leopard server itself. We have an outside router, a Cisco 2811. This router provides routing for both the public IP range, and the NAT range is configured in this router. The forwarding dns is located in LR and Fayetteville. So what I need is dns on Snow Leopard to forward outside queries to the state DNS servers, and resolve the local NAT IP only for Open Directory and a set of Snow Leopard clients.
Is this going to be possible?

How to resolve network issue or dns to access web page on snow leopard server?

I have my network setup like as follows:
internet > router 1 > ethernet ports > switch > router 2
I have a mac osx snow leopard server connected to "router 1", but it is so slow when accessing a web page hosted on the server from a browser on a workstation connected to either router 1 or router 2?
Is there a problem with my network setup or maybe because I changed the name to newservername.local?

@Jeff and @Camelot,
I think it is a DNS issue. I completely reset the DNS settings on server and the local name with the steps below, but now cannot access the site hosted on the server at all
I used a modified version of http://www.mkahn.com/2010/09/configuring-dns-on-mac-os-x-10-6-snow-leopard-serve r-for-hosting/ to reset the server set
1. Stop DNS Service in Server Admin
2. Close Server Admin
3. Obtain 10.6 DNS Default files (below)
4. Overwrite the DNS files with DNS Default files:
/etc/dns/loggingOptions.conf.apple
/etc/dns/options.conf.apple
/etc/dns/publicView.conf.apple
/var/named/named.ca/etc/named.conf
/var/named/named.local
/var/named/localhost.zone
5. Restart your server
All machines have 1ms ping responses within the network including this snow leopard server that I am trying to setup. There is another test web server that return pages instantly within this network so I doubt it is a network issue, but a DNS issue.

Error configuring services from Snow Leopard Server to Mountain Lion Server

I am trying to upgrade a Snow Leopard Server Mac Mini to Mountain Lion Server.
We have two Mac Mini servers at our office (production and backup) so I migrated the everything from our production server to the backup using the migration assistant when setting up the backup computer.
I now have the backup at home trying to upgrade it to Mountain Lion Server. I have downloaded and installed Mountain Lion as well as the Server App version 2.2. I basically followed the simple directions found in the Apple documentation.
I started the server app and it got to the part where it said "Upgrading services". After running for a few minutes, I get a window that states "An error occurred while configuring your server." It also sayd "The following actions failed or were not attempted:" with a red dot next to "Upgrading services". The other three items: "Authenticating to local directory", "Reading directory configuration" and "Authenticating to local directory services" have gray dots so I'm sure they were not even attempted.
Our Snow Leopard server is setup for SMB file sharing, LDAP services, FTP, Web, DNS, DHCP.
Can someone point me to where I can figure out what exactly is failing? Are there specific log files I need to look into?
Thanks

Have EXACTLY the same issue - also tried reinstalling mountain lion server fresh and still had the same problem...

Nslookup Snow Leopard Server DNS problems

I have a mac mini that I'm trying to turn into a snow leopard server. Attached to the mac mini I have three external hard drives which act as back ups to our mac book pro laptops. I have installed the server software and downloaded all the updates and I can see the drives on the server and I can acess the external drives and backup to them with out a problem. The issue that I have is that when I run nslookup I get an error message which tells me that it can't find my name and that I need to rerun so software commands.
I'm also unable to run either dns or podcast producer which was the main reason for buying the server software. I have a static ip address and believe I have configured everything correctly but I just can't seem to sort out the DNS and problems.
Any thoughts - thanks

Snow Leopard Server DNS setup

Where is there a step by step setup for making my Snow Leopard Server with DNS? Essentially, I am looking to setup a mail server but seem to be missing what information I need to gather from the folks that host my domain and how to point traffic to my network.

When I started setting up my first Mac OS X Servers a few years ago I had to completely retrain my brain because the MacOS does not follow the traditional nomenclature of Windows Active Directory and DNS setup. That being said like AD for Windows MacOS relies very very heavily on a healthy and properly running DNS system, both internally and externally. So one great resource I found was about 10+ hours of training on Leopard Server over to Lynda.com. I think you can sign up for a month long membership but it's well worth the investment if your looking for some basics thru advanced setup of Leopard Server. Now SLS is much much easier at the setup and deployment and some of the fundamentals of the setup interface have changed greatly (as an improvement) but the videos are still very applicable.
Basically it comes down to the following steps in order to get your website/e-mail/wiki services working.
1. Purchase your .whatever with a registrar, godaddy, doster, network solutions ect...
2. Make sure you have a fully routable PUBLIC IP address from your ISP that you can assign to the WAN (internet side of your router)
3. Contact your ISP and ask then to create an rDNS entry for your .something to the IP address they assigned you. Usually this will look like xxx.xxx.xxx ---> mail.mydomain.com when you test later on.
4. Modify the DNS records with your registrar to point the MX & A record to your new IP. You will log in create an A record for mail.mydomain.com ---> xxx.xxx.xxx (your public IP on router) and then you will create an MX record for e-mail which will simply be mail.mydomain.com with a value of 10 (there is usually a screen for this).
5. Once all the DNS is setup and working properly (Can take several days for these changes to take affect and be visible by your ISP) then you can begin the configuration of your router. You will need to determine what IP internally you want your Mac to be. Usually 10.0.0.1 or 192.168.1.1 or other and document that. Program your router to port forward ports 25,110, 80, 143 to the IP that you decided your Mac will be at so those services will be publicly available to you to user. Otherwise nobody will ever be able to send you e-mail or visit your site.
6. This is a good time to check your work and settings by visiting www.mxtoolbox.com and you verify your rDNS (setup by ISP) and your DNS (Setup by you) before beginning your setup of OS X SLS. If everything checks out then start the install if not STOP HERE and fix it because it will haunt you in the long run.
7. Start the install of SLS and at some point the system will get you to the screens at which you input your domain information. If all was setup properly up to now SLS will auto-populate the domain and local hostname of your Mac Server. U can change the local hostname if you wish but the domain name information should reflect your rDNS and A record information of mail.mydomain.com and you can hit next and proceed with the rest of the install.
8. Once up and running you will need to make a small adjustment to the alias of your e-mail. For some reason the engineers at Apple left a flaw in (my opinion) that is as such. Whenever you send e-mail it will go as [email protected] instead of what you really want which is [email protected]. So follow this post below and you will be all fixed up in a jiffy.

Upgrade from Snow Leopard Server to Lion Server hangs at configuring services...

I am running the Mac mini with snow leopard server 2.53 ghz 2GB of ram, 2x500GB hard drives, and have followed through the process to install Lion Server. The installation appears to be hung at the Configuring Services section of the setup process. I have left it for a couple of hours and nothing has progressed.
Should I leave it longer, hoping that it will work through the process (if in fact it is working through something)?
How long should this normally take?
As this is my work server, hosting mail, web, FTP, and file sharing, it is rather important to get it up and running as quickly as possible.
Any thoughts on how I can get it moving?
Hard power off of the Mac Mini reboots the machine, then proceeds back to the setup page, and then hangs on the same Configuring Services.
Any assistance would be much appreciated.
Thanks.

Lion Server Upgraders,
beware and proceed with caution.
Apple web site is naively optimistic on the upgrade process:
"To upgrade your Mac to OS X Lion, you don’t need to drive to a store, bring home a box, and install a bunch of discs. All you do is click the Mac App Store icon, buy Lion for $29.99, and your Mac does the rest. Just make sure you have what you need to download Lion to your Mac."
And then has a 3 step process...
This is completely miss leading.
Read this document first: http://manuals.info.apple.com/en_US/lion_server_upgrading_migrating.pdf
It will make it readily apparent that moving from Snow Leopard Server to Lion is not going to be simple.
Having done this twice now.. I have found that:
1. Open Directory migration is a weak point. Lion & Snow Leopard Open Directory are not compatible, so if you have masters & replica then expect trouble. I have an unresolved issue trying to get a simple Lion Server to Lion Server Open Directory replica up and running. This compatibility seems to also cause migration to fail, as I found that all my local User/Groups transferred ok but non of the /127.0.0.1/LDAPv3 (Open Directory) ones did. This is a very important item, as all the mail accounts in dovecot use LDAP generated UID, so you have to be careful that you do not loose mail accounts.
2. Mail - your mail aliases will not transferred, so you will need to reapply the aliases.
3. Web Server Setup - This broke, under migration as I gather the entire Web serving tree has changed. In particular I had "Snow Leopard" Web Mail (which is based on Squirel) on my "Snow Leopard" Server and this is now dead...
4. Digital Certificates - I found that the valid (ie signed by trusted CA's) did not get migrated, so I had to re-imported my Digital Certificates. If you have paid for third party CA certificates then make sure you have got these copied somewhere, as if you loose them then you will likely need to go to your provider and get a certificate revocation and new certificate, which will cost you money!
Cheers,
Zebity.

How do I configure snow leopard server to allow local client to access the server using its public domain name

I have SLS 10.6 running on my local network with DNS configured.
I can access the server from a client on the lan using server.local or server.domain where domain name is my publically registered domain,
From the internet I can access my server using the registered domain name i.e. www.domain.com.
Is it possible to set my server up so that www.domain.com also reaches the server when used by a client locally? At present I get a page not found error.

The configuration you're aiming for is called split-horizon or split-brain DNS, and it's quite possible. It can get slightly hairy when you have different stuff using the same host name for different purposes, for instance, and you'll need to track all external DNS entries in your internal DNS server when you're running "split".
Here is how to set up DNS services. Split-horizon is one of the options listed there.
My preference is to use a different domain or subdomain within the network, and to avoid using split-horizon where I can reasonably manage it. One domain name is configured for and reachable outside and is effectively public, and the other domain (or a subdomain) is inside and private and only reachable directly or via VPN, for instance.

Snow Leopard Server running extremely slow all of a sudden!!

Hi, I'm not a qualified server technician but am currently trying my best to run a server in a Secondary School! Please help, need to fix ASAP.
So basically we've got a Mac Pro running Snow Leopard server which has become incredibly slow in the past week. Nothing has changed in our department to trigger this. Here's everything I know so far...
- If I try to log on to the admin account when "Some Network Accounts Are Available", log on will take under a minute. If I try to log on to the admin account when the light goes green and "Network Accounts Are Available" log on will take forever and eventually just crash and which point I have to just force a shutdown and try again.
- When I can log on, some aspects of the computing seems fast and other aspects are really slow. For example, a few programs open as soon as I log on no problem, however a simple spotlight search or trying to open Sytem Preferences will crash the computer completely.
- Have tried booting in Safe Mode, and everything ran fast and how it's mean to but once restarting and booting normally the problems remained.
Sorry for the lack of knowledge!!
Thanks in advance.

Your comment indicates "crash the computer"? Do you mean that OS X Server itself fails, and you have to reboot? Or that the application crashes, and you have to restart it?
The following are some general approaches toward gathering some data:
Launch Console.app from Applications > Utilities and see if there are blocks of repeating errors.
Launch Terminal.app from Applications > Utilities and issue the following harmess, diagnostic command:
sudo changeip -checkhostname
After entering an administrative password and possibly seeing a one-time informational message about sudo, you should see some network configuration information and then an indication that no changes are required, or that there are DNS or network errors.
Boot from the Snow Leopard installation DVD and run a volume verification pass using Disk Utility, this from the Utilities menu of the installation disl.
FWIW...
If the applications or OS X Server are crashing, then you're generally heard toward either a reinstallation of the software, or a hardware repair, or quite possibly a combination of the two.
Forcing a hard shutdown can lead to corruptions, depending on exactly what's going on when the power drops out; that's probably best left as a last-resort approach and one best avoided.

NEW to Snow Leopard Server - Config Q's

I recieved a free Mac Mini Server running Snow Leopard Server and would like to get some help configuring it. I would like to get FTP and VPN service running. I've already purchased a domain name with 1and1.com, but don't have the slightest idea on how to get the domain name to point to my server. Can anyone give me some pointers on how to do this as well as getting the 2 services running? Also, are there any good books on OS X 10.6 server?
Thanks in advance!

Does your Internet connection have a static IP address? If not you will need to use a service like DynDNS.org and if you want to use it with your own purchased domain name you will need to use the paid for level of service.
I use the free DynDNS service with Snow Leopard VPN with no problems. You would in both cases download and install the Mac client for DynDNS so it can update your domain name record.
Would you be using Open Directory? If so you would need to setup an internal domain name server, it is possible to use the same domain name both internally and externally - this is known as a split horizon DNS setup.
Apple's own Snow Leopard Server documentation can be accessed here http://support.apple.com/manuals/#server 10.6 with regards to third-party books, I cannot comment from personal knowledge as to which is best but a selection can be viewed via http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dstripbooks&field-keywo rds=mac+10.6+server

SNOW LEOPARD SERVER PROBLEMS REQUIRE CERTIFIED CONSULTANT TO HELP

I've had a pretty unstable Snow Leopard server install since it was upgraded from Leopard a few months ago. Some of the problems were said to be hardware related, but I've been unable to migrate it to a different computer (Mac Mini).
The current installation is running, albeit poorly.
We had a Mac consultant involved in these issues, but he has proven to be unstable and unreliable as well - so we're on a search for a new consultant to give us some paid assistance in straightening this thing out.
We're not on the US mainland, but can make the server accessible by ARD and/or SSH to someone.
Someone with Apple certification would be preferred.

Hi Brian,
I'm an IT consultant dealing with Mac OS Servers and Windows Servers as well as Linux. I can offer a few helpful suggestions since just recently I transferred data from a Mac OS 10.5.8 Server to a 10.6.2 Server.
My first question to you is what data are you immigrating from? example 10.5.8 Server Data to 10.6.2 server?
The reason why I ask this since IMAP data in 10.5.8 and before was using Cyrus and starting in 10.6 apple switched to Dovecot.
Initially, I did not realized that apple made the switch and had stalling problems using the apple migration tool. (Personally I don't think the tool works well since a lot of others are running into this problem when researching this issue).
In the end I decided it was best to important everything manually, mail and not use the apple immigration tool since I think it has some issues.
The first thing I would do is make sure the DNS is configure right so that the server can resolve it's name which is very important.
Hopefully you're been running Open Directory . Export the users from the old server and import it to the new 10.6.2 server.
Next transfer the IMAP mail from 10.5.8 server to the 10.6 server to the same locations.
Example in 10.5.8 server default location is
/var/imap
and
/var/spool/imap
note this is where cyrus stored imap data in 10.5.x and maybe before. I have to look at my old 10.4 server since I'll be upgrade my own server soon.
My clients Servers have been upgrade fine by doing the manual method.
anyway...
keep those two locations in mind of where you mail is stored.
next I would copy your old cyrus mail to the new server. Don't use the migration tool at all. Just setup the new server and get the DNS running so it can resolve itself before you do this.
also make sure mail server is not running and it's off.
open up a terminal window
copy and paste this but change the name of the volume/hard drive name (HD_name)
sudo /usr/libexec/dovecot/migratemaildata.pl --cyrusBin "/Volumes/HD_name/usr/bin/cyrus/bin" --database "/Volumes/HD_name/var/imap" --sourceSpool "/Volumes/HD_name/var/spool/imap" --targetSpool "/var/spool/imap/dovecot/mail"
ok do this will convert all of your cyrus mail to dovecot. Make sure you've already imported the users from Open Directory before doing this script.
after all of this
there's still one more step
for some reason the postfix "main.cf" file is configured to use cyrus in 10.6.2 update.
/etc/postfix/main.cf
you can use the pico editor if you like.
example
type in at terminal window
sudo pico /etc/postfix/main.cf
it should be near the end of the file
don't bother with anything that's in # which is ignored.
look for
mailbox_transport = cyrus
then change it to
mailbox_transport = dovecot
save the changes
edit settings in the mail server with server admin to what you had... I recommend don't importing the mail settings from the old server admin since some people reported that its better just to manually configure it.
however for other server admin settings you might try to export and import to the new server.
If you have any questions just let me know and I'm glad to help the mac community.

I transferred files from a NAS server to the Mac Mini Snow Leopard Server and now some of the files have Custom Access and can't be opened by some users. How do I fix this?

We're setting up our Mac Mini Snow Leopard Server, and in the process transferred files that had been stored and accessed from our Blackarmor NAS server over to the Mac. These files were all created on PC's and are Office Excel files, WordPerfect files or PDF's. When you look at the files on the Mac from the Mac and bring up Get Info for the affected file, it says that the file has Custom Access. The files that work properly don't have that configuration. I can access and open the files on some computers, but some users can't open the files from their computer even though they can see it. We're all using PC's and they get the Error: Access Denied-Contact your administrator--or something similar. I've seen on the web similar issues and it may have something to do with ACL permissions. I don't know enough about Mac OS to understand this, but what is baffling is that they can be opened from some PC's but not others, and all of the Users have the same accessibility to the files. Thanks for a solution!!
