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 =…

Replace the macOS Server DHCP Service with bootp
View Your Old Settings 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. But it can absolutely be run on a Mac. 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_array dhcp:subnets:_array_id:22217FF5-4DDB-4841-A731-EF5DA080E672:WINS_primary_server =…

Setup NetBoot On OS X Server 5 for El Capitan and Yosemite
The NetBoot service allows administrators of OS X computers to leverage images hosted on a server to boot computers to a central location and put a new image on them, upgrade them and perform automations based on upgrades and images. Since the very first versions of OS X, the service has been called NetBoot. In the Server app, Apple provides a number of options surrounding the NetInstall service, based on Automator-style actions, now calling the service NetInstall. The first step to configuring the NetInstall service is to decide what you want the service to do. There are three options available in System Image Utility (available under the Tools menu of…

Setup The DCHP Service In Yosemite Server
DHCP, or Dynamic Host Control Protocol, is the service used to hand out IP addresses and other network settings by network appliances and servers. The DHCP Server built into OS X Server 3, installed on Yosemite running the Server app (aka Yosemite frickin’ server) is easy-to-use and fast. It’s pretty transparent, just as DHCP services should be. To install the service, open the Server app and then click on the Show button beside Advanced in the server sidebar. Then click on DHCP. At the DHCP screen, you’ll see two tabs: Settings, used for managing the service and Clients, used to see DHCP leases in use by computers that obtain IP…

Configure Static Addresses On A Meraki
Most Meraki appliances come with DHCP enabled on the WAN interface. Once you connect to the Internet through such a configuration you can claim the device using your Meraki account and then configure it. However, what if the Internet connection at your location won’t actually work with a DHCP WAN address. If you need to configure a static WAN address in order for your appliance to connect to the Internet then you’ll need to first connect an Ethernet cable to a LAN port of your appliance and your computer and make sure to disable any other interfaces on your computer. Also configure the network settings to use DHCP. Then open…

Provide VPN Services Using Mavericks Server
OS X Server has long had a VPN service that can be run. The server is capable of running the two most commonly used VPN protocols: PPTP and L2TP. The L2TP protocol is always in use, but the server can run both concurrently. You should use L2TP when at all possible. Sure, “All the great themes have been used up and turned into theme parks.” But security is a theme that it never hurts to keep in the forefront of your mind. If you were thinking of exposing the other services in Mavericks Server to the Internet without having users connect to a VPN service then you should think again,…

Installing the DHCP Service in Windows Server
With the DHCP service no longer in the Server apps provided by Apple (for the most part), it’s important to look at alternative solutions to host the service. The DHCP Service in Windows Server is a Role that a Windows Server can fill that dynamically assigns IP addresses to client computers requesting addresses. The DHCP Role is easily added using the Server Manager application, available in the Administrative Tools menu of the Start Menu. Once opened, click on the Add Roles button. At the Select Server Roles screen, locate DHCP Server and then check the box for it, which will allow you to click on the Next button. At the…

Sticky DHCP Leases in Mac OS X
I did an article some time ago about how DHCP leases work. From that, I’ve gotten a number of questions about why, after you click on Renew DHCP Lease in the Network System Preference pane, you sometimes see the information until you get a new lease. You can also reset the lease from the command line, which does not usually show you a new lease in the GUI immediately. To reset the DHCP lease from the command line, use ipconfig: ipconfig set en0 BOOTP ipconfig set en0 DHCP If the information is displayed on the screen, then it has to be stored somewhere, right? When your system sends an acceptance…
