We have ES with Opendistro security plugin:
Node to Node encryption: https://opendistro.github.io/for-elasticsearch-docs/docs/security-configuration/ 1
How do we verify the node to node encryption is happening.
We sent an indexing request to Leader IP, and in the replica IP we saw tcpdump ( as internode communication is TCP ) but there was no luck.
Could someone help us how to verify node to node encryption?
