The first step to moving services from macOS Server for pretty much all services is to check out the old settings. The second step is to probably ask if where you’re going to put the service is a good idea. For example, these days I prefer to run DHCP services on a network appliance such as a Synology. And so let’s look at how to do that. Here, we’ll use the serveradmin command to view the settings of the DHCP service: /Applications/Server.app/Contents/ServerRoot/usr/sbin/serveradmin settings dhcp The output is an array of subnets with different settings per subnet. dhcp:static_maps = _empty_arraydhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:WINS_primary_server = ""dhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:dhcp_router = "10.15.40.1"dhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:WINS_secondary_server = ""dhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:net_range_start = "10.15.40.2"dhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:net_range_end = "10.15.43.253"dhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:dhcp_domain_name =…

Using the Caching Service Command Line Interface
The Caching Server in OS X Server 5 is pretty simple, right? You open up the server app and then click on the On button and you’re… off… to… the… races… Yup. There are also a few options that you can configure using the Server app. You can configure which IP addresses (or networks) are able to access your server. You can configure where the cache is stored. You can configure the amount of Cached used. And you can clear out that cache. Boom. Including the ON button, you’ve only got 5 things you can do here. Pretty easy. To script kicking off the service as just a proxy that…

Obtain Information About OS X Server Using serverinfo in Mavericks Server
OS X Mavericks Server (Server 3) comes with the /usr/sbin/serverinfo command (introduced in Mountain Lion Server). The serverinfo command is useful when programmatically obtaining information about the very basic state of an Apple Server. The first option indicates whether the Server app has been downloaded from the app store, which is the –software option: serverinfo --software When used, this option reports the following if the Server.app can be found: This system has server software installed. Or if the software cannot be found, the following is indicated: This system does NOT have server software installed. The –productname option determines the name of the software app: serverinfo --productname If you change the…

Preserving the Chain of Custody for Mac OS X

One way to do this is to use a physical write blocker so that when you plug a USB, SATA, eSATA or other type of drive into the write blocker you will only be presented with a read only volume on the computer. For example, some good write blockers can be found at Digital Intelligence. WeibeTech also makes a nice USB device for write blocking on the Mac. But this can get kinda’…
