Caching server and IPv6 support

Anyone know if it is possible to configure the server for caching to work if you are using a dual stack IPv4 and IPv6 network.

When running dua-stack all client devices will prefer IPv6 when it is possible so set cache server service from Apple is to see every customer who logs as coming from a separate network rather than a single network. It doesn't seem to be a way to configure the server caching on OS X Server 5 for an IPv6 subnet, it accepts IPv4 addresses.

Before that I have to submit this as a bug can someone prove me wrong with a workaround to get a double network stack to work with caching server.

I got this job, it was just a matter of editing the configuration file server caching by hand to add the IPv6 range.

The configuration file is located in /Library/Server/Caching/Config/Config.plist

Make sure that the caching server does not work as you change the configuration file.

Open the file in the Terminal for editing and search for the following text:

< key > PreviousDataPaths < / key >

< table >

< string > / library/server/cache/data < / string >

< / array >

< key > region < / key >

< string > 65622637284725D55356E27799AC1535 < / string >

I will use the example of a range of IPv6 for the following subnet, 2001:377:3f:65ec: / 64

Change the configuration file to add the IPv6 range as follows:

< key > PreviousDataPaths < / key >

< table >

< string > / library/server/cache/data < / string >

< / array >

< key > PublicRanges < / key >

< table >

< dict >

< key > first < / keys >

< string > 2001:377:3f:65ec:0:0:0:0 < / string >

< key > last < / key >

< string > 2001:377:3f:65ec:ffff:ffff:ffff:ffff < / string >

< / dict >

< / array >

< key > region < / key >

< string > 65622637284725D55356E27799AC1535 < / string >

Now add the TXT DNS record in the zone file located in /Library/Server/named/db.example.com

_aaplcache._tcp 259200 IN TXT "prs = 2001:377:3f:65ec:0:0:0:0 - 2001:377:3f:65ec:ffff:ffff:ffff:ffff.

Now start the update server cache and restart the DNS server if it is running.

  • Apple caching server in a Windows domain?

    Hello

    We seek to add caching to the Apple services to our WIndows domain. It seems that we need a DNS server to do? Does anyone know the DNS settings, which can be placed on our servers DNS Windows to Apple devices point to the caching server?

    Thank you

    If your PC can access the internet using your DC as DNS server (which is the usual case in an Active Directory environment) then you will should not do something else. But a man of what DNS it is, is not the same as another. Anther thing that you should be aware, that's if your environment uses a proxy. In which case you may need to this twist a bit then as caching and access is not limited somehow.

    There are some useful articles/guides you might look at first before moving forward:

  • Caching server - you can remove individual files?

    Hello, I'm running a server from caching on a Mac Mini 10.11.6.

    Today, the iTunes 12.5.1 update came out, but none of my systems are able to install the update of the caching server. Download package, so they fail. I think that the download must be corrupted. I turned off the server and then update of iTunes on one of the clients, and it worked. So I think that the copy on the server is bad.

    Is it possible to find and remove the correct file in the packages cached so that it will download a new copy? Or do I have to reset the entire cache?

    Hi W.Loring,

    Try these two suggestions:

    -Run under sudo:

    /Applications/server.app/Contents/ServerRoot/usr/sbin/serveradmin caching settings: LogClientIdentity = true

    /Applications/server.app/Contents/ServerRoot/usr/sbin/serveradmin stop caching

    /Applications/server.app/Contents/ServerRoot/usr/sbin/serveradmin start caching

    - then check service log hiding in.app for clues

    -Check: Configure OS X Server Advanced Cache Settings and set LogLevel, restart the cache service and check the alternative log file for clues.  Remember that performance will decrease with this context.

    hope this helps, dwbrecovery

    It is an intermittent problem. It is not always the case.

    Thank you in advance.
    Jack

    This is a warning and harmless, if bulky to the error console.
    It is not your problem, whatever it is. It is a warning that your server doesn't support security. But is nothing important in the world of ISPS who refuse to do security as it complicates things and increases their support costs.

    As an indicator, perhaps it indicates your anti virus having a fit. Try disabling anti virus scanning email and see if the error Stops. I have a suspicion it will be.

  • iPads not working only not with the cache server

    Hello!

    We have implemented a Server Cache El Capitan... And the strange thing is that it works with macs and iPhones but not with iPads! Has anyone of you ever heard of something similar?

    Thanks in advance!

    Carl

    It works with macs and iPhones but not with iPads!

    There are many variables that affect how to find caching servers Apple devices.  Signed iPads on the same account iCloud like Macs and iPhones, or more precisely, are the accounts that iPads are signed in registered in the same country as the public IP address of the server being cached?  If your organization uses multiple public IP addresses, are the server cache and your DNS server set up correctly in what concerns these addresses?  Did you restart the iPads after implementation of the caching server, so that they immediately "forget" that they have found no update server caching and are forced to review?  (Restart devices - not the server!-is also recommended if you change the public address record in DNS.)  IPads use a different local subnet as other devices, maybe a caching server is not configured to serve?

    We can help you, but we need more information.

  • Caching server does not not (El Capitan)

    I recently implemented a mac Server (new mac mini OS X app 5.0.15 Server 10.11.3,).

    In order not to interrupt the old server (active), it was the first facility with an address in the range 192.168.1.x and DHCP server caching has been enabled and I could see the content was stored on the server.

    Later (about a month), it has been changed to be the Active Server and the IP has been changed to static in the scope of the 10.0.10.x.

    After that, change the caching server has failed.

    I tried:

    • Restarting the server.
    • Turning and the update server caching.
    • Change the location where to save the content.
    • Reset content. (So all the old content has been deleted).
    • Increase in the size of how much it can hold.
    • Made sure the permission is set to all networks

    It works flawless on the other servers I'm running (other locations) but not on this one. And the State is green and says everything is fine.

    Any suggestions on what to do?

    TIA,

    Peter

    the IP address was changed to static in the scope of 10.0.10.x

    Have you changed your whole network this network block? If this is not the case, the caching Service does not work.

  • Server does not support remote façade panels

    Hello.  Hope someone has an idea about that.  After the computer host and update cDAQ 9139 LabView SP1 from 2013 to 2014 LabView dev suite shipped by NOR, I get the error "server does not support the remote panels" when you try to view my remote panel.  Before the update it worked normally.

    I went through everything in the list in this document, http://digital.ni.com/public.nsf/allkb/C23EF1551D8C52ED86256B140073EE2E and can't find anything that will solve the problem.

    I have rebuilt the application in 2014 of LabView (I even tried a new simple project with a single loop, one of the temperatures and a remote control), rebuilt the build spec and get the same error.

    "I've re-edited the web page and checked in the html code it refers"CODEBASE ="ftp://ftp.ni.com/support/labview/runtime/windows/2014/LVRTE2014min.exe" and I have, according to MAX, LabView DURATION 14.0.1 installed on the host machine.

    If something has changed related LabView 2014 which would cause a new firewall as this remote façade program worked great with 2013 installed?  I've already added that LabVIEW 2014 and all other related apps through the firewall, including the web server.  I am also on a machine that doesn't have a Bluecoat, our company network/internet security suite is installed.

    Thank you

    Michael

    Another possible solution to this problem - operator error.

    See one of my other posts here for details, but I made an assumption about the port numbers and what they apply to.  Two key points - the port of the web server application in the configuration of hardware web page is not the port used to access the remote panel - port is assigned in the properties of the device, the server settings remote control panel in the project.  And they cannot use the same port; This will also lead to the error "server does not support the remote panels.

    Note to the NOR - you must add this to your KB document on the resolution of this error.

    Thank you!

  • Newbie question: can a LabView script or exe run on a Web server and interact with PHP?

    Hi all

    I am a complete newbie. I had to have an existing LabView project and have been asking if it can work with a PHP Web site. I would like to be able to create a form (for entry) on a Web page, and then go this LabView project entry existing. The existing LabView project then treats the input and generates a text file that the user wants to download from the site.

    So my question is, is it possible? If so, how to configure it and what products/costs might be involved?

    Thanks in advance

    Hi Andy -.

    There are a few limitations "Remote panels" who probably will not do what you are trying to do as possible.  First, the remote panels have only runs on a Server Web of LabVIEW, and this server does not support PHP.  Integrate a web site that uses a web server with more features of LabVIEW is to put the server on a different port and then use an iFrame or something to integrate LabVIEW remote panel page into your own web site.  Communication back will probably have to use another protocol tansportation or to read and write files that they read and write.

    I highly recommend that you look in another function to LabVIEW, called "Web Services".  These are quite a bit different approach of the remote control and are available only on version 8.6 and later (and probably only editions of developers).  Services Web of LabVIEW allows you to perform a LabVIEW program (or modify an existing one) to connect back using XML.  It is a common place to consume and send commands to a Web Service of LabVIEW by using something like PHP or Flash.  However, you are responsible to provide interfacing features in the language that you use that consume the Web Service of LabVIEW.  For example, instead of a graphic on the front, you would need graphical data output and a PHP program that can do something with it.

    Web Services are quite handy if you need a 'light' client, as well as material interaction features of LabVIEW.

    Hello

    ·         What operating system do you use?

    Step 1:

    I suggest you to update the firmware of the router on the manufacturer's Web site and verify that it helps. For more information on how router update contact your router manufacturer's support site.

    Step 2:

    Try to assign the static IP address for an Xbox 360 and the laptop and check if it helps.

    To assign a static IP address for your laptop:

    one) click Start > Control Panel > network and Internet > network and sharing Center and click on change adapter settings.

    (b) select your network adapter. (if you have more than one list) Right-click on the adapter and choose 'Properties' from the list.

    (c) under "this connection uses the following items," click once on "Internet Protocol Version 4 (TCP/IPv4) to select it and then click on the button 'Properties'.

    (d) click the radio button for "use the following IP address:" enter the static IP address, you want to use in the IP address box.

    (e) press "Tab" when you are finished and that the "Subnet mask" value should automatically populate with the correct value.

    (f) Finally, you will need to enter the IP address of your default gateway and the IP addresses of your favorite servers and auxiliary DNS.

    (g) the default gateway is the IP address of your router. The DNS addresses are usually provided to you by your ISP.

    (h) click on 'OK' to save your changes, and then click 'OK' again on the local area network connection properties window. You have now assigned to your computer a static IP address in Windows

    To assign a static IP for Xbox:

    (a) turn on the console and press "Guide" on the controller to bring up the quick menu.

    (b) go to the 'Settings' tab, then open "System Settings." The dashboard opens and the 'System settings' menu.

    (c) select 'Network settings' in the menu new. Another list of menu options is displayed. Choose "Configure network." This opens the network configuration menu, where you can set a static IP address. Note your IP address, subnet mask and gateway.

    (d) change your settings 'IP' to 'Manual' instead of 'automatic '. This will allow you to manually select your IP address and other settings. It can also erase your current settings, that's why you need to write.

    (e) change the last three digits of the IP address. Enter the same numbers for the subnet mask and the gateway that you saved in step 3. Press 'B' to exit from the menu and save the changes
