macOS sharing command line shortcuts

001_macOS_sshd_terminal.txt

# Sometimes GateKeeper / SIP / FullDisk Access gets in the way of enableing various services on recent version of macOS
# It is possible to check if this is the case using these commands. The GUI tends to just hang. The apprach below will
# provide you with some feedback. Perhaps an update to macOS at some point will display a dialog box telling you why 
# the service is not abe to start.

# check sshd status
sudo systemsetup -getremotelogin

# enable sshd 
sudo systemsetup -setremotelogin on 
# enable sshd (forcefully)
sudo systemsetup -f -setremotelogin off

# disable sshd 
sudo systemsetup -setremotelogin off
# disbale sshd (forcefully)
sudo systemsetup -f -setremotelogin off

# sometimes, on some version of MacOS things are really broken with the built in SSHD system.
# you can try the following command to turn on sshd
sudo launchctl load -w /System/Library/LaunchDaemons/ssh.plist

# to turn off this will do the job
sudo launchctl unload /System/Library/LaunchDaemons/ssh.plist

# If that fails then the next step may be to ditch the system (re-insteall) or possibly use your own seperate 
# (non-native apple sshd server) - openssh is a good choice.

# This command may assist you with issues starting ARD / ScreenSharing Server / VNCD on macOS

# It is possible you may need to write the launchd override .plist file. (do not do unless you need to).
sudo defaults write /var/db/launchd.db/com.apple.launchd/overrides.plist com.apple.screensharing -dict Disabled -bool false

# configure a shortcut for kickstart
ardkickstart="/System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart"

# This kickstart appraoch is generally a better approach if you do not want to use the GUI to set up users (modify as needed)
sudo ardkickstart -activate -configure -users localadmin -access -on -privs -all

# enable remote management # seems to work if kickstart or GUI fails
 sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.screensharing.plist

# restart ard
ardkickstart -restart -agent
