In Part-1 we learned about salt basics and its installation. In this part we will focus on the working of salt and also talk about proxy-minion for Juniper devices.
To start let’s begin with defining the master configuration on the master01 host.
Please use editor of your choice (like vim or nano) to edit file /etc/salt/master and add following two entries

root@master01:~# cat /etc/salt/master
interface: 0.0.0.0
auto_accept: True

The interface with all zeros means that the master will listen for minion on all available and active interfaces. It is obvious, that it is possible to restrict the master to minion communication on a specific interface also by defining the IP address of that that specific interface.
As explained in the Part-1, the master and minion communication are secured and they exchange keys. The entry “auto_accept: True” will accept the keys from minion(s) as and when they are started since this is a controlled and demo environment. In practice we keep it as “False” so that we accept the minion’s key manually and no unauthorized minion can connect to the master
