Generate a key pair on your Master distribution point (DP) that the script will use for authentication to each of your remote DPs, by running the following command in Terminal (copy/paste).
/usr/bin/ssh-keygen -q -t rsa -f "$HOME/.ssh/jamfMasterDP" -N ""
This will create your private key and public key files in your home folder:
~/.ssh/jamfMasterDP
~/.ssh/jamfMasterDP.pub
Use the ssh-copy-id command/script (built in to macOS 10.12 Sierra) to copy your public key (jamfMaster.pub) to each of your remote DPs. This requires you have Remote Login (SSH) enabled on your remote servers.
/usr/bin/ssh-copy-id -i $HOME/.ssh/jamfMasterDP admin@remotedp.server.com
Replace admin in the command with an admin account for the remote DP.
Replace remotedp.server.com in the command with the FQDN or IP address of the remote DP.
Enter your password for the remote server when prompted.
Repeat this step for each of your remote DPs.
Run this command (one line) manually in Terminal for each of your remote DPs:
/usr/bin/rsync --archive --human-readable --verbose -e "ssh -i $HOME/.ssh/jamfMasterDP" --delete --progress --stats /local/path/to/Packages/ admin@remotedep.server.com:/remote/path/to/Packages/
Replace /local/path/to/Packages in the command with the full path to your Packages folder on your Master DP.
Replace admin in the command with an admin account for the remote DP.
Replace remotedp.server.com in the command with the FQDN or IP address of the remote DP.
Replace /remote/path/to/packages/ in the command with the full path to your Packages folder on your Remote DP. It should look something like "/Users/Shared/CasperDP/Packages/".
Repeat this step for each of your remote DPs.
On your remote DPs, locate the Packages folder and verify the installer packages match your Master DP. As you add items to your Master DP or remove items from it, run the rsync command again. It will match the contents of your remote DPs to that of your Master DP.
You should see output in Terminal that looks similar to this:
