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?
