Mac OS X Lion Server :: Round Robin DNS For Load Balancing Between Multiple Network Adapters
Feb 20, 2012
I'm attempting to use 'round robin' DNS to load balance between the two ethernet adapters of an Xserve.Both ethernet adapters are connected to the same LAN and have static IP addresses of 192.168.2.250 and 192.168.2.251.The DNS zone for the server's local domain/host (macserver.private) has a machine record with both IP addresses (set up in the Lion Server UI).Having read up on round robin DNS, I would have expected DNS requests for 'macserver. private' to be answered with the two IP addresses ordered at random, achiving my aim of requests being served at random via each ethernet adapter.
However this doesn't seem to be the case. Doing a 'nslookup' from any of the network clients results in the two IP addresses being listed in the same order everytime. And pinging 'macserver.private' only ever results in a response from the same address.Does anyone know why this is the case? Does Lion Server use a non-standard DNS configuration? Are there any additional settings I need to configure in Lion's DNS server to make adopt a round robin approach to responding to requests?
I'd like to setup a network account on Lion Server and allow that account to VPN in to my server. But I want this account to have limited access to my LAN, similar to how the stovepiped "Guest Network" works with Airport Extremes. I don't see any way to assign specific network accounts specific IP ranges outside the normal, say, 10.0.1/24. Is there even any way to assign a specific account something in the range,say, 10.0.2/24? Any way to further limit network access for Lion Server VPN sessions?

I just got a new macbook air with SSD, 8gb memory... it was running fine all last week but this morning I'm getting all sorts of memory errors and page load problems across all browsers. I haven't installed/uninstalled anything and haven't changed any system settings recently. Some pages load fine, both others load without stylesheets, others time out, and others throw memory errors:Â
I am having difficulty binding clients to multiple open directory servers. All clients are running Lion. This issue did not occur under Snow Leopard. The servers are both Mac OS X Servers running Open Directory. There are two domains to which the client is successfully bound (DomainA and DomainB). If a user attempts to login using credentials from DomainB, they log in successfully but home folders are "not in the expected location" - so no data is present. If I unbind the client from DomainA and then attempt to login using credentials from DomainB, the issue is resolved. Is there a way to set a priority for how the client binds?Â
I have a Mac Mini running Lion Server. We are going to use it for software update, profile manage , vpn, ect. When I'm not on the LAN I can load the [url]... however when I'm on our LAN I'm unable to load this site. I can start load the site from the LAN by putting,[url]..., but the page then redirects to [url]...auth?redirect=[url]... and will not load because of the domain name. This problem is also causing me to not be able to push profiles to machines while they are conected to the LAN.
My goal is to be able to load the site from anywhere as [url]...
I have a small business with 4 computers. I'm wondering if I can keep all the user directories and shared files on a Mini with OS X server and also have the users share the applications that are on OS X server? Is this possible or can you only share the actual files, not the use of programs? I don't quite get why you'd have the user directories on the server rather than each computer.
Is it possible to create more than one email address for the same user? I want to be able to distinguish between emails originating from my website, or an email client as well as to identify different tasks for the same user - one for office administration, general information, etc...Â
I'd prefer to avoid creating non-existant "users" to represent tasks, if possible.
I am using Workgroup Manager to set the CatalogURL for software updates. Can I set multiple url's for software updates so if one address is not reachable the client will look for the next URL?
I'm looking at OS X Server as a possible email server upgrade from an OLD Linux box. On our current server we have aliases setup to archive all incoming and outgoing email to another account. That one account then checks email via POP and then it is archived on another client computer for record keeping and CYA. It looks like this:Â
I'm trying to setup a macmini server with four different firewire drives (has this working in 10.6.8 working great) however in lion server you can only have ONE timemachine backup destination.apple put an Share items/Backups folder with a .com.apple.timemachine.supported file in it. and set permissions to a group com.apple.backup_access However i can't dublicate this setup and have the system accept an extra folder on another drive.Â
I have just purchased my first mac (Mini Server w/ quad i7) the other week. I am having serious troubles connecting it to the internet at my work or uni networks. The mini works just fine at home with a simple connection to the modem/router. But at uni there is a small infrastructure and proxy, and at work there is a more complicated setup also (although the firewall isn't blocking any ports or normal internet traffic. There also isn't any MAC address filtering on any of the networks). I have tried both ethernet and WiFi, with no success.Â
Mac mini obtains local IP, can successfully contact the DNS. Pinging locally to the gateway fails (so so does pinging google, or external addresses). traceroute also fails internally. But that's about as far as I can go on either work or uni networks.
I've fiddled around with all settings i can find under 'Advanced' in the network options. But again nothing.Â
It is a completely fresh install of OSX 10.7.3, no 3rd part apps or software have been installed yet (this is due to not having an internet connection).Â
I am COMPLETELY new to mac software - other than knowing the dashboard is down the bottom, the taskbar is up the top and the minimizing/closing is in the top left corner. I am in the 3rd year of my IT degree at uni, so I know some generic networking troubleshooting, but that's about all.Â

I have an Open Directory Master running on my 10.7.3 Server machine, and I created network account server entry in "Users & Groups -> Login Options" which is non-functional ("This server is not responding") using the loop back 127.0.0.1 and entering the diradmin credentials.Â
I have created another entry which is functional, and I can access my network accounts, but I cannot delete the original entry. The minus key is greyed out and I can't work out how to unbind.Â
last month our Xserve G5 with Leopard Server which controlled user accounts in our computer labs died. We replaced it with a Mac mini server (that includes Lion Server) –by the way, this is the first server that I ever setup–.During initial configuration, the server was fully updated to Lion server 10.7.3, and stablished as an OD Master. I didn't import anything from the old server, so all accounts and groups and preferences and everything have been defined from scratch.Everything was working good until I finish the setup and try to connect from one of our Leopard client machines. I configure that machine with Directory Utility with settings from the server, and the server responds just fine, the client sets everything up automatically for authentication and contacts. Everything seems to be normal until I log out and try to connect with one of the network accounts.The account will not login, the login window just shakes and does nothing. Odd enough, the login window tells that network accounts are available (captures are in Spanish). When I login again as a local admin account, I check Directory Utility and when I look at the LDAP configuration, in the search & maps tab of the window, I find these two red registers (UserAuthenticationData and OLCLDIFConfig). I don't know if this is related to the problem, but this is where I get stuck and don't know where else to go.
Our new Lion Server has a static IP Address pointed to over the internet by our registrar's zone file. Planning the Lion Server installation process with the intent of hosting Web, Mail and Open Directory services to a small number of users who are nearly all located off-site. I do also want Lion Server to be a caching DNS Server and DHCP authority on the local network to replace what dnsmasq does on our current Linux server.
I am looking forward to offloading some of the lower level Linux administration tasks and putting myself in the hands of the Lion Server Setup Assistant and Server App :-) but at the same time don't understand some of its assumptions and fear having to spend a lot of time experimenting and re-installing.
So, specifically, I want the Server App to know that my Lion Server has a "Host Name for the Internet" but that the DNS it sets up will not be the DNS for my zone - I will be managing that through my registrar's interfaces.
Second problem is my fnot understanding what name space devices on the local network will / should use. e.g. The Linux server will be available for backups etc on the local intranet (and optionally have a static ip address on the Internet) but MacBooks, PCs, iPads and iPhones will be served ip addresses by the Lion Server's DHCP. So will / should these dynamic devices have their machine names fully qualified by our domain name with RFC 1918 style ip addresses or something like .local? How do I tell this to Lion's Server App / Setup Assistant? How easy is it to update these initial settings later?
My mac is set to automatically connect to the internet, but since downloading Mac Lion 10.7.3, I'm having problems. I have to reconnect to the internet repeatedly throughout the day. I also recently updated Microsoft office - not sure if that's somehow related.
I have set up a server with several network profiles. When logged into a network profile the user has no problem creating and saving a file of any kind, as soon as you edit and try and resave one of these files (only those of utilize Versions) does it give you an error "The file cannot be saved." at which point it reverts back to the origional file or offers to save it under a new name. Through trouble shooting I've discovered it only happens when trying to resave files that use versions, and only happens when im accessing these accounts through the network profile (in other words if i loggin and screen share to the account everything works fine), which in tern suggests the problem is occuring in the disconect between the home folder(which is all the network profile accesses) and the applications.
I have Intego VirusBarrier X6 in several macs. When using it with normal/local/mobile users, I do not have any problem. However, when logging as network user (I have a mac mini with lion server 10.7.4), the macs hang after a while. At the beginning, I tried everything: permissions, firewall, sharepoints, etc on both the client and the server. Only when I uninstalled the software on the client, everything works again normal.Â
I've setup my server and enrolled a few devices. Everything works fine if I'm in the same LAN but as soon as I tether my laptop to my cell service and try to issue the remote lock nothing happens till the laptop is back on the network and it gets the lock request. I have changed the hostname of the lion server a few times if that broke something. Also the server is behind a NAT so do ports need to be forwarded?
I have a problem with Network Users defined on my Lion Server accessing the server through VPN or Profile Manager (via Safari) ... I keep on getting authentication errors. Is this because they are network users or am I missing something else?
This works: when I logon to my Lion Server with either local or network users everything seems to be OK including home directory synchronisation.
I tried the following for VPN:my local server account can logon to the server (ie my secret key, user account/password combination are OK ("chap peer authentication succeeded for ...")when I try the same with two of my network accounts I keep on getting authentication errors (VPN) but I'm sure I use the same userid/password combinations as above ("chap peer authentication failed for ...")
I get similar results when I access the Profile Manager (url..)my local server account can logon on to the Profile Manager and sees as all the informationwhen I try this with one of my network accounts (which has devices assigned) I keep on getting 'incorrect user name or password
I have a 2009 Mac Mini Server with iStat Server installed. When I connect to iStat server with the iPhone app, I see no network usage (even though it is being used). iStat Pro widget will show the usage just fine. Any ideas on why its not showing up with iStat Server?
I'd like to have my RGB values in Photoshop produce the same values in Keynote and Powerpoint. That is, I'd like to have the blue of my logo (128, 215, 236) appear identically in all three programs by typing the value into the color picker.
I've been using Safari 4 for a while now and I am starting to notice that with multiple tabs and sometimes when I go to certain pages it tends to take a while to load - which is really annoying. I tried Google Chrome but it doesn't have a bookmarks manager which is just stupid. I hear that Firefox takes a while to start up.
after color balancing a clip I get a flickering border on top and bottom of my clips, visible in timeline and also after rendering. It's easy to see in this clip (starts around 15 seconds in): URL....
If I remove the color balance it will go away. I wonder if it has to do with the source clip being in 1080i instead of p. The preceding clip is also color balanced but is in 1080p. It's less noticeable but sometimes still there when other color correction is invoked. I'm using a late 2013 Haswell 27 in iMac with 8gb ram.

This never used to be a problem before the latest Safari update:When I try to open a window of the other Gmail account that I am logged into (multiple sign in), it always freezes close to the end of loading it.All the more reasons to use Chrome.Always forced to use basic HTML mode but it has very limited functionality.

I have heard that there is a free app that is able to share your computer processor load over the network to another computer. I have an iMac and would like to see if I could get my MacBook Pro to also work out things, running in parallel.
So if for example I want rip a movie or work out Pi to a billion decimal places (which i dont ) I can have both computers working on this task.
What happens is that i attend a school, where we are 700 people using the same internet. Actually it's divided into 4 sections, so there are probably 250 in my group. This network is protected by a WPA2 password, and has additional login forms, which gives the school the ability to check all in- and outgoing transfer. However, I have lately been getting some problems connecting. What happens is that I connect, and it works for about 2 minutes. Then, it just won't load any sites and just keeps trying to load until it finally admits that it can't retrieve the server. It's my third year. and I have never experienced this before, so I thought: Well, gotta be the school's internet, but i haven't heard of any other ones having this problem. This makes me worried that my macbook's airport extreme card is broken.
I was wondering if anyone had experienced a similar problem, or maybe could give a hint towards a solution? I am running a 13 inch macbook unibody (the silver one), with the newest system and all upgrades installed. Problem is: The airport extreme card is located in the display. I don't get why, but it makes me not want to change it myself, should it be destroyed.
