Ports and protocols allow node-to-node communication paths in NSX-T, the paths are secured and authenticated, and a storage location for the credentials are used to establish mutual authentication.
By default, all certificates are self-signed certificates. The northbound GUI and API certificates and private keys can be replaced by CA signed certificates.
There are internal daemons that communicate over the loopback or UNIX domain sockets:
KVM: MPA, netcpa, nsx-agent, OVS
ESX: netcpa, ESX-DP (in the kernel)
In the RMQ user database (db), passwords are hashed with a non-reversible hash function. So h(p1) is the hash of password p1.
To get access to NSX-T nodes, you must enable SSH on these nodes.
