    Enabling and Disabling SSH in Munki Update

    Posted on 1 min

    Munki MacOS

    I previously posted a munki nopkg script to enable SSH using /usr/sbin/systemsetup This stopped working on newer versions of macOS at some point and I implemented a new method, but never posted it. The new method simply loads the launch daemon to enable SSH.

    The install_check script

    	<key>installcheck_script</key>
	<string>#!/bin/bash

#check to see if ssh is off
(/bin/launchctl list | grep ssh)

if [[ $? = 1 ]] 
then
	# exit 0 to tell Munki an install is needed
	exit 0
fi
# if not needed, exit 1
exit 1</string>

    The postinstall_script :

    	<key>postinstall_script</key>
	<string>#!/bin/bash

/bin/launchctl load -w /System/Library/LaunchDaemons/ssh.plist

(/bin/launchctl list | grep ssh)

if [[ $? = 0 ]] 
then
	exit 0
fi

exit 1</string>

    And finally the uninstall_script :

    	<key>uninstall_script</key>
	<string>#!/bin/bash

/bin/launchctl unload -w /System/Library/LaunchDaemons/ssh.plist</string>
