fixing permission denied issue with udp 512 port graylog

Posted on by admin

use iptables to pre-route NAT the udp port :

 

iptables -A PREROUTING -t nat -i eth0 -p udp –dport 514 -j REDIRECT –to-port 10515

 

This will bypass the limit in the OS to ports < 1024 to non=root users .

Installing sample data in elastic search

Posted on by admin

After installing elastic search it is useful for testing and training to load some sample data.

1) create mapping :

curl -XPUT http://localhost:9200/shakespeare -d '
{
 "mappings" : {
  "_default_" : {
   "properties" : {
    "speaker" : {"type": "string", "index" : "not_analyzed" },
    "play_name" : {"type": "string", "index" : "not_analyzed" },
    "line_id" : { "type" : "integer" },
    "speech_number" : { "type" : "integer" }
   }
  }
 }
}
';

2) Load the data using the bulk api:

wget "https://github.com/ropensci/elastic_data/blob/master/data/shakespeare_data.json?raw=true" -O  shakespeare.json

curl -XPUT localhost:9200/_bulk --data-binary @shakespeare.json
