Mac Mini, two NICS and DNS
Hi everybody,
I'm not able to properly set up DNS role in Snow Leopard server with two nics. This is my situation:
NIC 01: WAN
Type: Builtin
IP: 192.168.1.252
SN: 255.255.255.0
GW: 192.168.1.254 (ISP Router)
DNS: 192.168.1.254
Domain: homenet.telecomitalia.it (ISP domain)
NIC 02: LAN
Type: USB
IP: 172.16.0.254
SN: 255.255.0.0
GW: empty
DNS: 172.16.0.254 or 127.0.0.1
Domain: mydomain.kzy
I'd like to provide DNS, DHCP, Directory service, print server with the LAN interface and use the WAN Interface only for internet access.Obviously all clients must have access to the web. In windows server there's a role called RRAS (routing and remote access) that allows sysadmins to do this quite easly, but in os x server I was not able to find nothing of similar. If i setup my server only with tha lan interface everything works great, but when I add the wan interface the dns stop working; seems that operating system confuse externale dns with internal dns. Obviously something is wrong in my configuration, please an anyone help me to solve this problem?
Thanks in advance
Alessandro
That's fairly typical of the problems encountered with OS X operating as an (expensive and slow and variously vulnerable) IP router. OS X Server can be configured as a gateway if you follow the set-up directions exactly.
It's local preference to configure either a commercial NAT-gateway-firewall-router box, or repurpose a spare two-NIC x86 box with M0n0wall, Smoothwall, pfSense or other open-source.
Preferably a box with a VPN server, but your 192.168.1.252/24 public-side IP address is going to cause issues with a VPN.
And in one reading of your configuration details, your ISP router is already a NAT-gateway-firewall-router box (based on that 192.168.1.252/24 private address you've shown), so you might want to investigate what its particular capabilities and features are. With that NAT assumption, you're headed toward double-NAT connection, and that'll play havoc with your networking. Single-NAT is problematic enough.
If that "ISP router" box is a NAT-gateway-firewall-router, then you'll be reconfiguring it for a subnet in your 172.16.0.0/12 or other private address space (which would make VPN pass-through more widely reliable), or moving your network into 192.168.1.252/24.
If you post the identity of the particular "ISP router", somebody might know its capabilities. Folks at your ISP almost certainly will, of course.

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. -
HT204144 I am on mac mini (mid 2011) and iphone 6 and trying to use airdrop but it is not working.
I followed all instructions but under mac finder, air drop is simply blank. I have set-up everyone on airdrop on iphone 6 in control center. Am I missing something. I am also on same network.
I read this paragraph:
In order to transfer files between a Mac and and an iPhone, iPad or iPod touch, your iOS device needs iOS 7 or later installed and your Mac needs to be a 2012 or later model. To transfer files between two Mac computers, you need one of the Mac models listed below and OS X Lion or later.
MacBook Pro (Late 2008 or newer)*
MacBook Air (Late 2010 or newer)
MacBook (Late 2008 or newer)*
iMac (Early 2009 or newer)
Mac Mini (Mid 2010 or newer)
Mac Pro (Early 2009 with AirPort Extreme card, or Mid 2010)
*The MacBook Pro (17-Inch Late 2008) and the white MacBook (Late 2008) do not support AirDrop.
--end--
So I am using mac mini mid 2011 and according to this line, I may not use it and need mac 2012, right? but why air drop is showing here on my mac mini is due to fact that transfer between 2 mac computers is possible if one is even of less than 2012 make.
I think I am clear now. Thank you and see if you have any thought on this? -
How do I pair my new Mac mini (mid 2011) and white Apple Wireless Keyboard (2003)?
I just bought a new Mac mini (mid 2011) and can not set it up via my Apple Wireless Keyboard (2003). I'm disheartened but not surprised that my Bluetooth 4.0 Mac isn't backwards-compatible with my Bluetooth 1.0 keyboard. But I can't find any documentation confirming the fact that my non-paired, but tested & perfectly functioning keyboard will not work with current Macs.
I was however, able to locate a tech support doc (http://support.apple.com/kb/HT4112) that mentions my Apple Wireless Keyboard (2003) is not compatible with iOS devices. (Which is not critical because iOS provides a non-physical keyboard. Aside, it would be lovely were Apple to add a non-physical keyboard to Mac OS X, if only so new desktop owners can continue to set up their Macs in a pinch.)I just bought a new mini mac (lion 2011) with a wireless keyboard. I could not get the mac to recognise the keyboard. Spent several hours back with the Genius team who replaced keyboard and mac but did not get anywhere. They gave me a wired keyboard, was able to configure the mac and then it recognised the wireless keyboard.
Seems this is a problem with the new mac/OS -
i buy a mac mini from amazon, and it is registered on another Apple ID, and i need to change it to mine, how can i do that, note that i can't contact the previous owner of this mac, what shall i do to set it under my Apple ID.
ThanksAs I said you need to:
You need to wipe the hard disk and reinstall the OS by booting into the recovery partition and reinstall the original OS via the internet. It will ask you to enter your ID

Just bought a new mac mini, wireless keyboard, and track pad. My track pad will not synch. All advise I have been given is to change items in the setting menu, but I cant because I still have to get through the setup!!
The power button for the Trackpad is on the right hand end of the battery case. Press that button to initiate the pairing process. On the top of the Trackpad just above the power button is a tiny green light (you probably cannot see it unless it is lighted). That light will indicate ehther or not the Trackpad is discoverable. If the Trackpad has discoverable the green light will blink on and off. If it does not pair within 3 minutes you will have to press the power button again to re-initiate the pairing process. Once your Trackpad has paired, you can just leave it on and it will pair automatically when you reboot your Mac.
If you are having problems pairing, try turning off any other Bluetooth devices within 30 or so feet of your Mac mini. That includes other Computers, iPhones, iPads, etc. that may be in the area. Once your Trackpad has pairedwith your mini, you don't have to be concerned about other Bluetooth devices.
One other hint, I find that although the Wireless Trackpad does not eat batteries as fast as the Magic Mouse it still uses more than the Wireless Keyboard. It is a good idea to keep a supply of AA batteries around. I have used Apple's Rechargable batteries, but found they did not last that long before needing to be recharged. I have had the best battery life from Duracell Quantum batteries. -
The PDF file and slideshow view corrupted using iPhoto. Macbook air only get corrupted slideshow and Mac Mini both slideshow and PDF file is corrupted.
Saving as a PDF file for some users have been a problem. If you boot into Safe Mode and run iPhoto you can create undamaged PDF files. We don't know why the problem but this is a workaround.
This problem prevents many from ordering books, calendars and cards since iPhoto creates PDF file of them for uploading and printing. Booting into Safe Mode lets them successfully order those items. -
Mac mini on photoshop and imovie
Hi, I am looking to switch over to Mac for non-professional photo editing and video editing. I have been looking at the mac mini basic model and upgrading the ram to 16gb. Is this a good option or is it worth waiting and saving up for the basic Imac. How does photoshop and imovie run on the mac mini?
You would definitely need 16GB of RAM and you can save some money buying the additional RAM from Other World Computing or Crucial. Photoshop is very RAM hungry, but perhaps even more hungry for CPU resources. If you are going to be doing a lot of Photoshopping I would go for a top of the line mini with the 2.6GHz quad core i7 processor and a Fusion drive. The fusion drive will yield disk I/O performance close to that of a full solid state drive (SSD) and that can be helpful with Photoshop as well. I have done some iMovie work on my fully loaded mini and I have been very pleased with the rendering speed and that is what seems to take the longest time.
If you already have a good monitor, that you like the fully tricked out mini would be a good buy for you. If you are going to buy an Apple monitor in addition to the mini, the price defference between that and a high end iMac will only be few hundred dollars and the iMac will be faster. I switched from iMacs to the mini because I bought a new iMac I always had to buy both the monitor and the processor. WIth the mini I only have to replace/upgrade one or the other.
Given you can no longer purchase Adobe products, they are available as rental only tools, you might want to consider some of the less expensive non-Adobe alternatives that are available on the Mac. You may find one of those that will give you the results you want and you can purchase for a fraction of what a year's rent of Photoshop will cost you some are even free. On the other hand Photoshop is still the standard by which all others are compared. -

AirDrop transfer between Mac mini (late 2012) and MacBook Pro (late 2008) works only one way.
AirDrop transfer between Mac mini (late 2012) and MacBook Pro (late 2008) works only one way. I see both machines on both airdrop windows. Firewalls on both machines are set exactly the same way, and with Network Browser set to allow. Can send a file from Mac mini to MacBook, but not the other way. Never get a window asking to accept on the Mac mini.
Found no useful documentation on AirDrop anywhere in the whole support site.Maybe this will work. From an Apple support article.
You can also use the Share button to send files to your neighbors via AirDrop. In a Finder window, select the item you want to share, and then click the Share button in the toolbar. For more information about the Share button, see this help topic: -

Mac mini 1.66 and pro-tools mbox 2?
i hope someone can help!
i just got the mac mini 1.66 and Mbox 2..and the pro-tools software installed flawlessly!
(pro-tools 6.8.1)but when i went 2 open the app up, it said no hardware was located .....but i had my m box plugged in..... when i got 2 my hardware overview....and checked what is plugged into my usb ports it says that the mbox is plugged in,but for some reason it is not turning on.
i read from a google search something about passive USB ports not working with the mbox..
but IDK...
i'm old school...i'm used 2 good ol analog and somewhat analog/digital...i used 2 record on a alesis ADAT machine....but i lost my studio 2 a flood......and i heard all the rave about Pro-tools....so i said what the heck!
but me and computers dont mesh...
please help
thanks very much in advance..

ABZ The beastHi AbzZilla,
I was looking up this post and found you've a similar problem...
I was having the non-responsiveness with the above configurations in 'LE 7.4 & 7.4.2c (Mac-only), but I have now installed Pro Tools LE 8.
Unfortunately I still can't get the MBOX2 to work with the Mac mini 2, but the MBOX2 USB status alights now [i.e. it's very bright and now works] on the MBP 17" ...all with Mac OS X 10.5.6! In all previous Pro Tools versions it confirms support for Pro Tools and the MBox, with the Mac mini:
http://archive.digidesign.com/compato/osx/os.cfm
So I too am 'stumped' as this is the brand new computer that I wanted the software to be operable on. I've swapped the USB cables (to check if it was a failed cable) and it looks like either a firmware clash or a USB-port power issue? I've also tried non-powered USB hubs... as it could be the later issue? So when I find my powered USB hub I'll let you know, ...if there's a change?
Until then... I Iook forward to further posts in this thread!
Thanks for kicking-off the discussion.
