I use logstash with embedded elasticsearch. My logstash config looks like the following:

output 
 tdout debug => true debug_format => "json"

 elasticsearch 
 embedded => true
 cluster => "logs"
 

When I issue command to see all opened ports by using

netstat -plunt

I get the following:

What means :::* in the third column are? Does it mean that embedded elasticsearch opens 9200, 9300 and 9301 ports for listening from anywhere?

If so how could I restrict elasticsearch to listen only from localhost?

netstat elasticsearch logstash

:::* you are right it listen from anywhere

To allow only to listen from localhost you can edit elasticsearch.yml file with next.

network.host: "127.0.0.1"
http.host: 127.0.0.1

You can also edit the iptables config and deny incoming requests to the (9200-9300) elasticsearch ports
