Q: Mavericks Caching Server Doesn't Work

Hey Everyone,

 

So I upgraded to 10.9, which is great, purchased the new Server, which is great and no matter what I do I can't get it to work. Which is not so great.

 

Here's the story:

 

1) Clean install of 10.9 on 2013 mac mini. Multiple times in fact.

 

2) Install OS > Configure Network (fixed eth ip) > Disable Wifi > Set Hostname > Configure App Store ID > Download Server > Install Server > Enable Caching.

 

3) Server is not a gateway and is connected directly to the LAN with a fixed IP (via time capsule). External IP confirmed to be the same between Server logs and the clients. Power saving is disabled (mini is on 24/7). Firewall is disabled.

 

4) Multiple clients running latest OSX / iOS. All using the same Apple ID as the Server. Tried some clients with a different ID from the same region (US) and from a different region (EU).

 

5) No matter what I do, the only stuff that's being cached is the system updates (itunes / codecs / etc.). Not a single OSX / iOS app is being cached.

 

6) Tried a variety of .plist changes, increased the log verbosity. No errors in Debug.log: normal registration, etc. But not a single OSX / iOS app is being cached. Downloading apps on clients doesn't do anything (i.e. doesn't spawn a single line of log), even with logging = verbose. Restarting the services doesn't reveal any issues, just a regular registration every single time.

 

7) Asked Apple for help, they asked for log files and remain silent since then (couple of days now).

 

I wasted so much time on this already. I'd be really grateful if anyone pointed me in the right direction (other than a wall with a "bang head here" poster).

    What we're saying is that is not happening.

     

    It's quite clear that Apple are claiming that an iOS 7 device, when updating its own apps or software will utilise the caching service. But this is what is NOT occurring. When OSX is doing the downloading, it uses Caching, but iOS 7 does not. At least, not for me and it appears some others and maybe many others who haven't thought to check.

     

    It cannot be anything to do with location etc since both my Mac and iOS devices are all in the same location (within feet of each other), use the same Apple ID and the same (Mac) App Store and Apple agrees they are all in the UK. It cannot be a location problem.

     

    There appears to a problem with iOS 7. It should "just work", but sadly, it "just doesn't".

    Same problem for me. The caching is working for all my OSX devices but not for my IOS 7 devices (2 iPhone and 5 iPad). I'm located in China and all my devices are conneced to the same French Apple Store account...

    I have bought a Mac Mini especially for caching, due to poor internet speed connection......

    Searching for help !

    Can confirm your statement. I wasn't having any problems while updating my ios6 devices. Now the Cache Serice is pretty useless (with iOS devices). But I'm not sure if iOS7 is the root cause . Maybe the 10.9.1 update ?

    Cache Service does work again. Bildschirmfoto 2013-12-21 um 17.55.54.jpg

    iOS 7 is not responsible for the failure of Cache Service.

     

    Server Service Logs:

    Cannot lock /Library/Server/Caching/Logs/AssetCache.pid: Permission denied; is Caching Server already running?

    Unable to save preferences to /Library/Server/Caching/Config/Config.plist

     

     

    Since I changed with chmod the permissions of  these two files, the Cache Service does work again as supposed.
    Know, this is a quick & dirty solution.

    PS

    sudo touch AssetCache.pid

    So iOS 7 devices are using the caching server for you now? Hmm I'll try that out.

    Just tested with an iOS7 device again: 100 %

    A point about raimattern's post of the Caching Service server panel, although it shows iOS Apps being cached, it makes no reference to whether those were downloaded by OSX (iTunes) or iOS. I do NOT have a problem with the former, only the latter. If I use iTunes to update all my iOS apps, everything goes through the Caching Server. But if I try to update an app using the actual iOS device, the download is directly to the iOS device and NOT via the server.

     

    I can see this by watching the traffic through my router as it tells me to where the data is being downloaded, so if it's being downloaded by the Server, or my Mac or an iOS device, it is 100% clear which it is. If an iOS device is downloading updates, ALL the data goes to the iOS device and the server gets NOTHING. This is wrong. When OSX downloads updates, all the data is actually being downloaded by the Server. As I said, it's quite clear what is happening (and what is not).

     

    The issue with permissions raises 2 questions:-

     

    What are the permissions that were apparently wrong and what did you change them to that seemed to make it work?

     

    Why are the permissions only a problem for iOS 7 devices trying to update whereas when OSX downloads updates the permissions are apparently NOT a problem?

    Interestingly, my iOS devices are now using the caching server. I'm not sure whats changed, but the bytes used now increases when I download an app on an iOS device (tewted on iPhone 5s running 7.1b2). Running "sudo serveradmin fullstatus caching | grep CacheDetails" before and after shows an increase in bytes used for IOS Apps.

    Same thing here. It looks like it's finally working correctly. iPhone 5, iOS 7.04, on the Canadian App Store.

    As expected, caching doesn't seems to work under iOS 6.1.5 (iPod Touch 4th gen).

    @Simon Comeau Maretl: Caching Server 2 is for iOS 7 and above.  See http://www.yesdevnull.net/2013/10/os-x-mavericks-server-setting-up-caching-serve r/.

    As for you others, I am now seeing that iOS 7 is caching correctly.

     

    I can be 100% certain that this was NOT occurring but now IS. By watching the traffic through my router, previously I could see that when downloading something appropriate on my Mac, all the data streaming from the Internet was going to the server, but when doing the same thing on any iOS device, the data was going to the device and NOT the server, i.e. caching was NOT working.

     

    Just tried again a download to my iPad and all the data went to the server, so caching is definitley now working correctly to iOS. There is no ambiguity here as I can see exactly to which device the data is being downloaded.

     

    There's been no upgrades to iOS 7, but has there not been an update to Server.app? Whatever, I have changed nothing within my network so it must have been a problem within Apple's software somewhere about which they've been rather quiet and has now been fixed without any admission of guilt. Hey, I'm grateful it's been fixed, but the perpetrators (i.e. Apple) really should put up their hands and say sorry.

    Just a heads up, for future googlers, mine didn't work due to the hardware serial number being over 12 characters because our Xserves are running VMWare ESXi hosting Mavericks Server and Windows 2012 server. ESXi gives a 18 character serial number to the OS X VMs which stops cachings erver working. The solution was to update from ESXi 5.1 to 5.5 which pruned the serials to 12 characters. If you server has had a new motehrboard and so a blank serial, you may also have the same problem as me.

    Nice right up, but caching server will not cache anything eventhough everything appears to be running correctly. (GUID and public IP has been masked )
