---------- DRAFT ----------
To exchange the configuration between a master and its slaves you need to be open the incoming port for any JobScheduler installation.
Assume you have configured your supervisor JobScheduler (master) with port 4440 and your workload JobScheduler installation (slave) with port 5000.
Than you have to be open incoming port 4440 at your master and incoming port 5000 at your slave (for TCP and UDP).
The outgoing ports used by JobScheduler are selected by the OS, therefore it is not predetermined which port numbers are used.
What becomes if UDP does not work?
The master uses UDP only as an "wake-up call" to the slave to speed up the process of updating. Independently of the UDP call, the slave ask from time to time the master for an update.
