Hello All, I have configured elasticsearch with ports 9200 and 9300. Everything works fine, as expected, but one configuration I haven`t founded: elasticsearch 0.90.10 3 indexes, each with 5 nodes without replicas Then I do 'lsof -i' , I get a huge list with open ports (ESTABLISHED) from 39619 - to 39634, and on another server running for experiments it makes ESTABLISHED connections from these ports : 43010 - 43025. Is it available to say in configuration, that it would use ports from 9301 to 9400? O maybe how I could know which ports it would take always ? Thanks. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

9200 and 9300 are the bindings for inbound traffic. Linux uses the higher ports for outgoing connections (eg from the node to other cluster members on 9200/9300).

No, linux uses a random port for outgoing connections. I'm not sure what the range is or how it's allocated, but my guess would be it uses ports from 32768-65535.
