So, I am running a caching server on macOS 10.12.3. We are having issues with this server not caching anything. I ran a few things to see what the deal was. Anyone have any ideas? The thing that sticks out the most is "caching:Port=0"

sudo serveradmin settings caching

caching:LogClientIdentity = "true"

    If you run the following on a 10.12 client

    /usr/bin/assetcachelocatorutil

    Does it return found 0 servers or does it return something like

    x.x.x.x:49472, valid until 2017-02-08 13:30:10; supports personal caching: no, and import: n/a, shared caching: yes

    did you run this on a client or the server itself, i.e. it found a server at localhost:49417 (or did you replace the ip with local host)

    @Kaltsas I ran this on the server itself. Here are the results on a client machine.

    It's not caching anything because the client doesn't think there's a registered caching server available. Caching Server only downloads something when a GET request is made from an applicable client.

    If you look at /Library/Server/Caching/Logs/Debug.log on the server you'll notice when a client makes a request. It will look something like

    2017-02-08 15:08:12.345 #QjR9rbVtP1fs Received GET request by "MacAppStore/2.2" for /apple-assets-us-std-000001/Purple111/v4/a8/cb/24/a8cb24bb-75f5-eede-73db-e3627320e109/dwr2030657491772019283.pkg

    Are the client and the server currently on the same subnet? If not you'll have to modify your DNS records to accommodate.

    https://help.apple.com/serverapp/mac/5.2/#/apd6015d9573

    Basically on NAT, on the same subnet it will all work automagically. Out side of that you'll need to make some modifications so Apple knows where to point clients when they make a request.

    @Kaltsas Do we need to modify the DNS on the Apple Server or in our DNS server?

    You will need to configure the applicable networks in server.app (serve clients with public addresses on other networks). You will then be able to generate the necessary records for your DNS server from the caching service. See the above link. It's pretty straightforward (assuming your network folks give you adequately defined ranges and are willing to update your DNS records)

    @kaltsas Added the new entries to DNS following the directions in the link you provided. Still not caching. The client is still getting 0 servers and the log on the server says the following:

    I'm really hoping that the caching service is more solid in 10.12. Ever since it's inception, it never worked nearly as well as Software Update service. And yes, I know they're different but Software Update is being depreciated. Even when everything is configured perfectly, we'd see random computers not use it for one reason or another. Apple's focus on management is severely lacking.

    My Caching server seemed to be working just fine up until I upgraded the server to 10.12. Then it stopped working. I'm getting the same symptoms you are where the server doesn't show any attempts to connect to it and nothing is cached or served out.

    I am glad I am not the only one experiencing this problem. Thanks guys! I guess we will have to wait for Apple on this one.

    I found out, that you will have to set up DNS on the server itself. Create the primary zone and just make the entry for your server. In the network settings point the DNS to your own machine (static IP = DNS IP). I had some caching servers which were not working while using an another DNS server then the one on the same machine.

    Setup DNS on the Mac server itself? Does that assume we then need to add that Mac server as a DNS server to all the client Macs? If so, that definitely won't work in my environment. We have to use the company's DNS servers (Non-Mac server OS) and getting the network admins to add anything to static entries requires an act of Congress.

    It's just very odd that everything was working fine under 10.11, then broke as soon as 10.12 was installed with no changes to any of the services' configurations.
