Tiny Deathstars of Foulness

Backblaze is a great cloud and on-prem backup tool for Mac and Windows. You can download Backblaze at 
https://secure.backblaze.com/download.htm. Once downloaded, extract the DMG and open the Backblaze Installer. 

At the Installer screen, enter your existing credentials or create a new account and click Install Now.

The drive will then be analyzed for backup.

By default, once the analysis is complete, the computer will immediately start backing up to the Backblaze cloud. Let’s click on the Settings button to configure how the Backblaze app will work.

This opens the Backblaze System Preference pane. At the Settings tab, you’ll see a list of drives to back up and an option to set when to receive warnings when the computer hasn’t completed a backup recently.

By default, performance is throttled so as not to cause your computer to run poorly. Click on the Performance tab. Here, you can disable that option, 

By default, backups run continuously, as files are altered. You can use the schedule screen to move backups to a specific time (e.g. at 1am every night). I personally like having continuous backups if you have enough bandwidth to account for them. 

By default, the whole system is not going to get backed up. Click Exclusions and you can see what will be skipped and disable some of the skips.

By default, backups are encrypted using public keys. I inherently trust the people at Backblaze. But I still use an encryption key to add an extra layer of security to my backups.

To set that, click on the Security tab.

At the Security screen, click on Enter Your Private Encryption Key.

Once you’ve got a good backup policy set. Click on the Reports screen to see what’s getting backed up!

Acronis True Image is a cloud-based backup solution. Acronis True Image is available at 

https://www.acronis.com/en-us/support/trueimage/2018mac/. To install, download it and then open the zip. 

Drag the Acronis True Image application to your /Applications directory. Then open Acronis True Image from /Applications. The first time you open it, you’ll be prompted to access the licensing agreement.

Once accepted, you’ll be prompted to create an account with Acronis. Provide your credentials or enter new ones to create a trial account. 

At the activation screen, provide a serial or click Start Trial.

At the main screen, you’ll first want to choose the source (by default it’s the drive of the machine) and then click on the panel to the right to choose your destination.

For this example, we’re going to use the Acronis cloud service. 

Click on the cog wheel icon at the top of the screen. Here, you can set how and when the backup occurs. Click Schedule.

At the schedule screen, select the time that backups will run. Note that unless you perform file level backups, you can’t set the continual backup option. For that, I’d recommend not doing the whole computer and instead doing directories where you store data. Click on Clean Up.

Here, you’ll define your retention policies. How many backups will you store and for how long. Click Encryption.

Here you’ll set a password to protect the disk image that stores your backups. The disk image can’t be unpacked without it, so don’t forget the password! Click on Exclusions.

Here, use the plus sign icon to add any folders you want skipped in the backups. This could be stuff you don’t need backed up (like /Applications) or things you intentionally don’t want backed up. Click Network. 

Here you can throttle the speed of network backups. We’ll skip this for now. Now just click on the Back Up button to get your first backup under way!

If you want to automate certain configuration options, check for the com.acronis.trueimageformac.plist at ~/Libarary/Preferences to see if the app has been launched, as you can see from the defaults domain contents:

{  SUEnableAutomaticChecks = 1;
SUHasLaunchedBefore = 1;
SULastCheckTime = “2018-04-07 21:33:01 +0000”; }

There are also log settings available at 
/Applications/Acronis True Image.app/Contents/MacOS/acronis_drive.config:

<?xml version=”1.0″ encoding=”UTF-8″ standalone=”yes”?>
<config><logging>
<channel id=”ti-rpc-client” level=”info” enabled=”true” type=”logscope” maxfiles=”30″ compress=”old” oneday=”true”/>

Synology is able to do everything a macOS Server could do, and more. So if you need to move your VPN service, it’s worth looking at a number of different solutions. The most important question to ask is whether you actually need a VPN any more. If you have git, mail/groupware, or file services that require remote access then you might want to consider moving these into a hosted environment somewhere. But if you need access to the LAN and you’re a small business without other servers, a Synology can be a great place to host your VPN services. 

Before you setup anything new, first snapshot your old settings. Let’s grab  which protocols are enabled, running the following from Terminal:

sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:enabled

sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:enabled

Next, we’ll get the the IP ranges used so we can mimic those (or change them) in the new service:

sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:IPv4:DestAddressRanges

Now let’s grab the DNS servers handed out so those can be recreated:

sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:DNS:OfferedServerAddresses:_array_index
sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:DNS:OfferedServerAddresses:_array_index

Finally, if you’re using L2TP, let’s grab the shared secret:

sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:L2TP:IPSecSharedSecretValue

Once we have all of this information, we can configure the new server using the same settings. To install the VPN service on a Synology, first open the Synology and click on Package Center. From there, click on All and search for VPN.

Then click on the Install button for VPN. Once installed, open VPN Server from the application launcher in the upper left-hand corner of the screen. Initially, you’ll see a list of the services that can be run, which include the familiar PPTP and L2TP, along with the addition of Open VPN.

Before we potentially open up dangerous services to users we might not want to have access to, click on Privilege. Here, enable each service for each user that you want to have access to the VPN services.

Now that we can safely enable and disable each of the services, click on PPTP in the sidebar of the VPN Server app (if you want to provide PPTP-based services to clients).

Here, check the box for “Enable PPTP VPN server” and enter the following information:
  • Dynamic IP address: The first DHCP address that will be given to client computers
  • Maximum connection number: How many addresses that can be handed out (and therefore the maximum number of clients that can connect via PPTP).
  • Maximum number of connections with the same account: How many sessions a given account can have (1 is usually a good number here).
  • Authentication: Best to leave this at MS-CHAP v2 for compatibility, unless you find otherwise.  
  • Encryption: Leave as MPPE optional unless all clients can do MPPE and then you can enforce it for a stronger level of encryption.
  • MTU: 1400 is a good number.
  • Use manual DNS: If clients will connect to services via names once connected to the VPN, I’d put your primary DNS server in this field.

Click Apply and open port 1723 so clients can connect to the service. If you’ll be using L2TP over IPSec, click on “L2TP/IPSec” in the sidebar. The settings are the same as those above, but you can also add a preshared key to the mix. Go ahead and check the enable checkbox, provide the necessary settings from the PPTP list, and provide that key and then click on Apply. Note that the DHCP pools are different between the two services. Point UDP ports 1701, 500, and 4500 at the new server to allow for remote connections and then test that clients can connect.

That’s it. You’ve managed to get a new VPN setup and configured. Provided you used the same IP address, same client secret, and the ports are the same, you’ll then be able to probably use the same profile to install clients that you were using previously.

Before we have this conversation, I want to give you some bad news. Your passwords aren’t going to migrate. The good news is that you only do directory services migrations every decade or two. The better news is that I’m not actually sure you need a directory service in the traditional sense that you’ve built directory services. With Apple’s Enterprise Connect and Nomad, we no longer need to bind in order to get Kerberos functionality. With MCX long-dead(ish) you’re now better off doing policies through configuration profiles. 

So where does that leave us? There are some options.
  • On Prem Active Directory. I can setup Active Directory in about 10 minutes. And I can be binding Mac clients to it. They’ll get their Kerberos TGTs and authenticate into services and the 90s will be as alive on your server as they are in Portland. Here’s the thing, and I kinda’ hate to say it, but no one ever got fired for doing things the old reliable way. 
  • OpenLDAP. There are some easy builds of OpenLDAP to deploy. You can build a new instance from scratch on a Mac (probably a bad idea) or on a very small Linux box. This is pretty easy, but to get all the cool stuff working, you might need some tweaking.
  • Appliances. I’m already working on an article for installing OpenLDAP on a Synology.
  • Microsoft Azure Active Directory. If you’re a primarily Microsoft shop, and one that is trying to go server-less, then this is probably for you. Problem is, I can’t guide you through binding a client to Active Directory in Azure just yet. 
  • Okta/Ping/other IAMs. Some of these can act as a directory service of sorts ( https://help.okta.com/en/prod/Content/Topics/Directory/About_Universal_Directory.htm ). As with Azure, you’re likely not going to bind to them (although Nomad has some interesting stuff if you feel like digging into that).
  • A hosted directory service provider (Directory as a Service) like Jumpcloud.
There are probably dozens of other options as well (please feel free to add them in the comments section of this article). No matter what you do, if you have more than a dozen or two users and groups, you’re going to want to export them. So let’s check out what that process looks like. The easy way to export data is to dump all of the services out with one quick command:

sudo slapconfig -backupdb ~/Desktop/slapexport/

This process produces the exact same results as exporting Open Directory from the Server App. To do so, open the Server app and click on the Open Directory entry. From there, click on the cog-wheel icon and choose the option to Archive Open Directory Master. 

When prompted, enter your directory administrator (e.g. diradmin) credentials.

Once you have authenticated, provide a path and a password to export the data.

Now you’ll see a sparse image in your export path. Open it to see the backup.ldif file.

That’s the main thing you’re looking for. The ldif file can be imported into another openldap system, or once you have an ldif file, you can also get that over into csv. To help with this, I wrote a little ldif to csv converter and posted it here.

Finally, you could export just users or groups, or specific objects from the Server App.

That option is more built for importing into other macOS servers, but if you’d like to try, click on Users in the left sidebar and then click on Export Users from the cog wheel icon towards the bottom of the screen.

Then select what to export and where to export the file to. 

You can also repeat this process for Groups, if needed.

/etc/Sudoers is a file that controls what happens when you use sudo. /etc/sudo_lecture is a file that Apple includes in macOS that tells your users that what they’re about to do is dangerous. You can enable a lecture, which will be displayed each time sudo is invoked. To turn on the lecture option in sudo, open /etc/sudoers and add the following two lines (if they’re not already there):

Defaults lecture=always
Defaults lecture_file = “/etc/sudo_lecture”

Then save the file and edit /etc/sudo_lecture. Apple has kindly included the following
Warning: Improper use of the sudo command could lead to data loss or the deletion of important system files. Please double-check your typing when using sudo. Type “man sudo” for more information. To proceed, enter your password, or type Ctrl-C to abort.
Let’s change this to:
Hack the planet.

Now save and open a new Terminal screen. Run sudo bash and viola, you will get your new message. Enjoy.

Apple has published a new page that goes through all of the settings and commands available via MDM and explains many in much more detail. This is available at http://help.apple.com/deployment/mdm/. The new guide is a great addition to the work @Mosen has done at https://mosen.github.io/profiledocs/ in terms of explaining what each setting, command, and payload do. And let’s not forget the definitive MDM protocol reference guide, available at https://developer.apple.com/library/content/documentation/Miscellaneous/Reference/MobileDeviceManagementProtocolRef/1-Introduction/Introduction.html#//apple_ref/doc/uid/TP40017387-CH1-SW1

Overall, I’m excited to see so much information now available about MDM, including how to develop an MDM properly, what each setting does, and now what you should expect out of an MDM!

Export macOS Server Data
We’re not going to import this, as it only takes a few seconds to configure new settings. Additionally, if you have outstanding services built on macOS Server, you might be able to pull this off without touching client systems. First, let’s grab  which protocols are enabled, running the following from Terminal:

sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:enabled

sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:enabled

Next, we’ll get the the IP ranges used so we can mimic those (or change them) in the new service:

sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:IPv4:DestAddressRanges

Now let’s grab the DNS servers handed out so those can be recreated:

sudo serveradmin settings vpn:Servers:com.apple.ppp.pptp:DNS:OfferedServerAddresses:_array_index
sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:DNS:OfferedServerAddresses:_array_index

Finally, if you’re using L2TP, let’s grab the shared secret:

sudo serveradmin settings vpn:Servers:com.apple.ppp.l2tp:L2TP:IPSecSharedSecretValue

Once we have all of this information, we can configure the new server using the same settings. At this point, you can decide whether you want to dismantle the old server and setup a new one on the same IP address, or whether you’d rather just change your port forwards on your router/firewall.

Ports

Before we configure any VPN services, let’s talk about ports. The following ports need to be opened per The Official iVPN Help Docs (these are likely already open if you’re using a macOS Server to provide VPN services):
  • PPTP: TCP port 1723
  • L2TP: UDP ports 1701, 4500 and 500
  • Enable VPN pass-through on the firewall of the server and client if needed

openvpn
There are a number of ways to get a VPN Server installed on macOS. One would be to install openvpn:

sudo port -v install openvpn2

OpenVPN has a lot of sweet options, which you can read about at openvpn.net.

SoftEther
One of the other tools Apple mentioned is SoftEther. I decided not to cover it here because it uses Wine. And I’m not a fan of Wine. 

Or Use iVPN

That will require some work to get dependencies and some working with files and network settings. Another option would be to install iVPN from here, on the Mac App Store. You can install it manually as well, and if you do, you’ll need to pay separately through PayPal, which is what we’ll cover here.

Once installed, if you purchased the license separately, use the Enter Manually button to provide it.

At the Registration screen, make sure the name, email, and serial are entered exactly as you see them in the email you received.

At the Thank You screen, click OK.

At the EULA screen, click Accept assuming you accept the license agreement.

Configure iVPN
At the main screen, you’ll have a few options, which we’ll unpack here:
  • Use Directory Server: Allows you to use an LDAP or Active Directory connection to provide username and passwords to the service.
  • Use custom accounts: Allows you to manually enter accounts to provide username and passwords for clients to connect to the 
  • Shared Secret: The secret, or a second factor used with L2TP connection.
  • Allow 40-bit encryption keys: Allows clients to use lower levels of encryption. Let’s not do this.
  • IP Address Range: The beginning and ending IP that will be manually handed out to client computers. When configuring the range, take care not to enter a range of addresses in use by any other DHCP services on your network or you will end up with conflicts.
  • Basic DNS: Allows you to configure a primary and second DNS server to send to clients via DHCP when they connect to the VPN interface.
  • Advanced DNS: Allows you to configure DNS servers as well as Search Domains.
  • Configure Static Routes: Allows you to specify the interface and netmask used to access a given IP.
  • Export Configuration Profile: Exports a configuration profile. When imported into a Mac or iOS device, that profile automatically configures the connection to the PPTP or L2TP service you’ve setup.
  • VPN Host Name: Used for the configuration profile so a client system can easily find the server w

If you configure Directory Authentication, you’ll get prompted that it might be buggy. Click OK here.

The Directory Authentication screen allows you to choose which directory services to make available to PPTP or L2TP. If the system hasn’t been authenticated to a directory server, do so using the Users & Groups” System Preference pane.

Once you’ve chosen your directory service configuration, if you require a third DNS server, click on Advanced DNS and then enter it, or any necessary search-domains. Click Done when you’re finished.

Click the log button in the upper left-hand side to see the logs for the service. This is super-helpful when you start troubleshooting client connections or if the daemon stops for no good reason (other than the fact that you’re still running a VPN service on macOS Server and so the socket can’t bind to the appropriate network port).

Finally, you can also create a static route. Static routing provides a manually-configured routing entry, rather than information from a dynamic routing traffic, which means you can fix issues where a client can’t access a given IP because it’s using an incorrect network interface to access an IP.

Once everything is configure, let’s enter the publicly accessible IP address or DNS name of the server. Client computers that install the profile will then have their connection to the server automatically configured and will be able to test the connection.

Configure Clients
If you configured the new server exactly as the old one and just forwarded ports to the new host, you might not have to do anything, assuming you’re using the same username and password store (like a directory service) on the back-end. If you didn’t, you can setup new interfaces with a profile. If you pushed out an old profile to configure those, I’d recommend removing it first if any settings need to change. To configure clients, we’ll install the new profile. When you open the profile on a client system (just double-click it to open it), you’ll see the Install dialog box. Here, click on Continue. 

Because the profile isn’t signed, you’ll then get prompted again (note: you can sign the profile using another tool, like an MDM or Apple Configurator). Click Continue.

Then enter the username that will be used to connect to the VPN and click the Install button.

The Profile can then be viewed and manually removed if needed. 

Click on the new iVPN entry in the Network System Preference pane. Here, you can enable 

Now that it’s easy, let’s click the VPN icon in the menu bar and then click on Connect iVPN to test the connection.

Once clients can connect, you can use the iVPN icon in the menu bar to monitor the status of clients.

In an earlier article, I mentioned that MAMP Pro was still the best native GUI for managing web services on the Mac, now that macOS Server will no longer serve up those patchy services. After we cover the management in this article, you’ll likely understand why it comes it at $59. 

So you’ve installed MAMP. And you need more than the few basic buttons available there. So MAMP Pro came with it and you can try it for a couple of weeks for free. When you open MAMP Pro, you’ll see a screen where you can perform a number of management tasks. This is a more traditional side-bar-driven screen that will look like what Server Admin might have looked like before the web services screen got simplified in macOS Server.

The Hosts item in SETTINGS will show you each host installed on the server. Think of a host as a site. Each web server can serve up a virtually unlimited number of websites. You can configure an IP binding to the site, or hav
 
If you click on the plus sign, you can add a site. In this example, I’ll add www.krypted.com and then click on create. When doing so, you can configure a database for each site (e.g. if you’re doing multi-tenant hosting), build a site off a template, or select a root directory for the site. 



The Apache tab of each host allows you to configure host-specific settings, including enabling options for directives such as Indexes, Includes, SymLink following, and CGI. More options than were in macOS Server for sure. You can also order allows, allow overrides, add new directives, set the index (or the default page of each site), add additional virtualhosts (such as krypted.com for www.krypted.com), and add a server admin email address. 

These were Apache-centric settings for each host. Click on the Nginx tab if you’re using Nginx instead of Apache. Nginx is a bit less “patchy” so there are a fewer options here. But they’re similar: Configure an index, add parameters, and a feature not available in the GUI options for Apache: allow or deny access based on IP.
 
The SSL tab allows you to generate a CSR, upload the cert and key file, and force connections to use https.

The Extras tab allows you to automatically install standard web packages. For example, here we’ll select WordPress.

Click on the Databases tab. To connect a site to a database, enter the name of the database when prompted. Note: the site itself will need credentials in order to connect, and if you’ve setup an “Extra” in the above step, the database will automatically be configured.

Next, let’s configure the ports used by the web servers. The previous settings were per-site. The rest that we cover in this article will be per-server, as these are global settings applied to the daemons themselves. Each of those services will have a port or ports associated with them. For example, the standard web port used is 80 or 443 for SSL-based connections and the standard port for MySQL is 3306. For publicly-facing sites these would be the standard ports, and given how common they are, there’s a button for “Set ports to 80, 81, 443, 7443, 3306”. Otherwise, you can enter each independently. Because the attaching of daemons is done here, this is also where you configure the user that services run as, as well as when to start the services and truncate log files.

The Editor option configures how the editor appears, which we’ll cover last in this article. The Editing option manages how the editor works (e.g. things  like tabs, autocompletes, etc.

The Fonts & Colors tab allows you to select each color assigned to various types of text.  

The Default Apps tab allows you to configure which app is opened when opening each type of file supported. 

Again, we’ll look at the editor later in this article. First, let’s finish getting the web server setup. Click on Apache. Here, you can load new Apache mods you download from the interwebs. I should mention that an important security step in locking down a publicly-facing web server is to disable all of the mods you don’t absolutely need. 

At the bottom of this screen, there’s also a handle little link to the directory with your logs, so you can read through them if needed.

The Nginx option underneath is similar. Access to log files is there, as is the ability to enable installed Nginx mods. 

The MySQL option also provides access to some straight-forward command-line options, but in a nice GUI. Here, you can configure a root password for MySQL ( which does this: Reset A Lost MySQL Password ), enable phpMyAdmin, MySQL Workbench, and Sequel Pro-based administration, enable network access to the MySQL Service (using ports configured in the Ports section of the app) which I cover at Allow Remote Connections To MySQL, and view logs.

The Dynamic DNS options are cool. Click there, and if your web server is behind a DHCP address, you can configure a dynamic DNS service including DNS-O-Matic, no-ip.com, dyn.com, easydns.com, etc. This way when you reboot and get a new IP address from your ISP, it’ll update the service automatically.

Memcached is a distributed memory object caching system. It’s used to make sites appear faster or to distribute caching between servers for systems that, for example, get clustered. It’s included here for a reason, I’m sure of it! Either way, I actually use it for a few things and like the fact that it’s there. To enable, simply choose how much memory to give it, configure the logging level (usually low unless you’re troubleshooting), and gain access to logs. If you check the “Include Memcached server in GroupStart” then memcache will fire up when you start your web services.

Click postfix. Here, you configure your server to route mail through an email account. If you run this from the command line, you can also configure your server to be a mail server; however, when you do that you’re likely to get mail bouncing all over the place. So if the server or a service on the server is supposed to send mail, it’s usually best to route through something like a gmail account. 

The Languages section allows you to configure how PHP, Python, Perl, and Ruby work on the server. For PHP, you can configure which version of PHP is installed, configure a version of PHP for hosts, enable caching (different than memcached), enable a few basic extensions (I’ve been playing with oauth a lot recently), choose logging options, and have a simple way to see the logs. 

Since you’re running on a Mac, you already have Python, but if you click on the Python option, you can make the version of Python bundled with Mac is 2.7.10 instead of 2.7.13.

Click on Perl to do the same.

Click on Ruby to do the same.

The editor is also pretty easy to use. Simply use the plus sign to add a file you’d like to edit. Keep in mind when browsing that everything MAMP Pro needs is self-contained in the /Applications/MAMP directory, so it should be pretty easy to find files for editing. 

And that’s it. This seems like a lot of stuff, but between sites like ServerFault and other Apache/Nginx articles, you’ll likely find most of the things you need. It’s worth mentioning that I consider this another baby step to just managing Apache using config files. macOS Server tried hard to reduce the complexity of where different settings and options are derived from; MAMP Pro makes no allusion that web server management should be so simple. That’s one of the things I like about it. It’s like you went from riding in a buggy on the back of a bike to riding with training wheels. The more you know, the better off you are.

Autopkgr is basically a small app that allows you to select some repositories of recipes and then watch and run them when they update. It’s a 5 minute or less installation, and at its simplest will put software packages into a folder of your choosing so you can test/upload/scope to users. Or you can integrate it with 3rd party tools like Munki, FileWave, or Jamf using the JSSImporter. Then if you exceed what it can do you can also dig under the hood and use Autopkg itself. It’s an app, and so it needs to run on a Mac. Preferably one that doesn’t do much else. 


Installing Autopkgr

You can obtain the latest release of Autopkgr at https://github.com/lindegroup/autopkgr. To install, drag the app to the Applications folder. 

When you open AutoPkgr for the first time, you’ll prompted for the user name and password to install the helper tool (think menu item). 

The menu item then looks like the following.

These are the most common tasks that administrators would run routinely. They involve checking Autopkg recipes to see if there are new versions of supported software titles, primarily. Opening the Autopkgr app once installed, though, shows us much more. Let’s go through this screen-by-screen in the following sections.


Moving AutoPkg Folders Around 

By default, when installed with Autopkgr, Autopkg stores its cache in ~/Library/AutoPkg/Cache and the repos are sync’d to ~/Library/AutoPkg/RecipeRepos. You can move these using the Choose… button in the Folders & Integration tab of Autopkgr, although it’s not necessary (unless, for example, you need to move the folders to another volume). 

Note: You can also click on the Configure AutoPkg button to add proxies, pre/post processing scripts, and GitHub tokens if needed. 


Keeping Autopkg and Git up-to-date

The Install tab is used to configure AutoPkg settings. If there is a new version of AutoPkg and Git, you’ll see an Install button for each (used to obtain the latest and greatest scripts); otherwise you’ll see a green button indicating it’s up-to-date. 

You can also configure AutoPkgr to be in your startup items by choosing to have it be available at login, and show/hide the Autopkgr menu item and Dock item. 


Configuring Repositories and Recipes

Repositories are where collections of recipes live. Recipes are how they’re built. Think of a recipe as a script that checks for a software update and then follows a known-good way of building that package. Recipes can then be shared (via GitHub) and consumed en masse. 

To configure a repository, click on the “Repos & Recipes” tab in Autopkgr. Then select the repos to use (they are sorted by stars so the most popular appear first). 

Note: There are specific recipes for Jamf Pro at https://github.com/autopkg/jss-recipes.git.

Then you’ll see a list of the recipes (which again, will make packages) that AutoPkgr has access to. Check the ones you want to build and click on the Run Recipes Now. 

If you don’t see a recipe for a title you need, use the search box at the bottom of the screen. That would show you a given entry for any repos that you’ve added. Again, all of the sharing of these repos typically happens through GitHub, but you can add any git url (e.g. if you wanted a repo of recipes in your organization. 

Once you’ve checked the boxes for all the recipes you want to automate, you can then use the “Run AutoPkg Now” option in the menu items to build, or rely on a routine run, as described in the next section.


Scheduling Routine Builds

Autopkgr can schedule a routine run to check recipes. This is often done at night after administrators leave the office. To configure, click on the schedule tab and then check the box for Enable scheduled AutoPkg runs. You can also choose to update your recipes from the repos by checking the “Update all recipes before each AutoPkg run” checkbox.


Getting Notified About New Updates To Packages

I know this sounds crazy. But people like to get notified when there’s a new thing showing up. To configure a variety of notification mechanisms, click on the Notifications tab in AutoPkgr.

Here, you can configure alerts via email, Slack, HipChat, macOS Notification Center, or via custom webhooks.


Integrating Autopkg with Jamf (and other supported vendors)

When integrating with another tool, you’ll need to first install the integration. To configure the JSSImporter, we’ll open the “Folders & Integrations” tab in Autopkgr and then click on the Install JSSImporter button.

Once installed, configure the URL, username and password (for Customer API access) and configure any distribution points that need to have the resultant packages copied to. 


Once the JSSImporter is configured, software should show up in Jamf Pro scoped to a new group upon each build.  It is then up to the Jamf Administrator to complete the scoping tasks so software shows up on end user devices.


What the JSSImporter Does from Autopkg

This option doesn’t seem to work at this time. Using the following may make it work:

sudo easy_install pip && pip install -I --user pyopenssl

Note: The above command may error if you’re using macOS Server. If so, call easy_install directly via 

/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/easy_install.py.

macOS 10.13 brings changes to sysadminctl. You know those dscl scripts we used to use to create users? No longer supposed to be necessary (luckily they do still work). Now you can create a user with a one-liner, and do other forms of user management, such as enabling FileVault for a given user, or managing the guest accounts. However, you can’t do these tasks as root or via sudo. You have to do so with other admin accounts per Apple kbase HT208171 (in fact, this article has been in my queue waiting for that issue to be fixed – but keep in mind I’m not prefacing these with sudo in the below commands). In the below command, we’ll pass the -addUser option and then use -fullName to fill in the displayed name of the user, -password to send a password to the account and -hint so we can get a password hint into that attribute:

sysadminctl -addUser krypted2 -fullName "Charles Edge" -password testinguser -hint hi

The result would be as follows:

No clear text password or interactive option was specified (adduser, change/reset password will not allow user to use FDE) !
Creating user record…
Assigning UID: 503
Creating home directory at /Users/krypted2


Notice that in the above, the system automatically selected a home directory and UID. We could have passed those as well, using Now let’s use dscl to view the user we just created:

dscl . -read /Users/krypted2

Here’s a snippet of the dscl output:

NFSHomeDirectory: /Users/krypted2
Password: ********
Picture: /Library/User Pictures/Fun/Ying-Yang.png
PrimaryGroupID: 20
RealName: Charles Edge
RecordName: krypted2
RecordType: dsRecTypeStandard:Users
UniqueID: 503
UserShell: /bin/bash


Notice that the above is not the whole record you’d typically find with dscl. But if it were, you would not have the AuthenticationAuthority attribute. To see if it can unlock FileVault we can use the -secureTokenStatus operator built into sysadminctl. Simply pass the RecordName and you’ll get an indication if it’s on or off:

sysadminctl -secureTokenStatus krypted2

The response should be as follows:

Secure token is ENABLED for user Charles Edge

To just get the ENABLED response we’ll just use awk to grab that position (also note that we have to redirect stderr to stdout):

sysadminctl -secureTokenStatus charles.edge 2>&1 | awk '{print$7}'

We could append the AuthenticationAuthority attribute with dscl, as we would need a SecureToken. To get a SecureToken, we’ll use the -secureTokenOn verb:

sysadminctl -secureTokenOn krypted mysupersecretpassword

To disable, we’ll use -secureTokenOff

sysadminctl -secureTokenOff krypted mysupersecretpassword

Given that we like to rotate management passwords, we can do so using-resetPasswordFor which takes a username and a password as -newPassword and -passwordHint respectively:

sysadminctl -resetPasswordFor krypted -newPassword newsupersecretpassword -passwordHint "That was then this is now"

Note: In the above, we quoted the hint, which is supplied using the -passwordHint option. If it was one word we wouldn’t have needed to do so. 

Next, let’s check guest access. You can have guest enabled for logging in, afp, or smb. To check if guest is enabled for one of these use the -guestAccount, -afpGuestAccess, or -smbGuestAccess options. Each has an on, off, and status verb that can be used to manage that account type. So for example, if you wanted to check the status of the guest account, you could use -guestAccount as follows (also note that we have to redirect stderr to stdout):

sysadminctl -guestAccount status 2>&1 | awk '{print$5}'

To then disable if it isn’t already disabled:

sysadminctl -guestAccount Off

You can also use sysadminctl to do a quick check of the encryption state of the boot volume using the -filesystem option (although there’s no on and off verb for this option just yet):

bash-3.2# sysadminctl -filesystem status

2017-12-07 10:37:26.401 sysadminctl[8534:466661] Boot volume CS FDE: NO

2017-12-07 10:37:26.434 sysadminctl[8534:466661] Boot volume APFS FDE: YES

The help page is as follows:

Usage: sysadminctl [[interactive] || [-adminUser -adminPassword ]] -deleteUser [-secure || -keepHome] -newPassword -oldPassword [-passwordHint ] -resetPasswordFor -newPassword [-passwordHint ] -addUser [-fullName ] [-UID ] [-shell ] [-password ] [-hint ] [-home ] [-admin] [-picture ] -secureTokenStatus -secureTokenOn -password -secureTokenOff -password -guestAccount -afpGuestAccess -smbGuestAccess -automaticTime -filesystem status Pass '-' instead of password in commands above to request prompt.

Why should you switch to sysadminctl for scripts? Entitlements and I’m sure this is how mdmclient will pass management commands in the future… Why should you not? You can’t run most of it as root…
