cannot connect to logstash on port 5044

[lakerzhou-lenovo]

I am testing the master ES version 5.6.2. My remote filebeat cannot access logstash via port 5044. I recommend enable 5044 port forwarding by default by adding the following line in logstash section at docker-compose.yml.
"5044:5044"

Not sure if that would be relevant, we don't have anything listening on TCP port 5044 by default.

docker-elk/logstash/pipeline/logstash.conf

Lines 1 to 5 in 6cd82cf

	input {
	tcp {
	port => 5000
	}
	}

maybe occupied by other program: try netstat -anp | grep 5044

@lakerzhou-lenovo I would recommend following @MarStarck advice and track which program is listening on that port. If that's Logstash it would mean you configured a custom input, which makes that port only relevant within your setup.

Hi, if you are using logstash with docker, try to make your port available for the other applications which are not in your container.
You can use the flag -p 5044 when you are installing the docker.
For example:

docker run -d --name logstash
-p 5044:5044
--restart=always
-e "XPACK.MONITORING.ELASTICSEARCH.URL=http://ELASTIC_IP:9200"
docker.elastic.co/logstash/logstash:7.0.0
