Can´t connect to dedicated serach server

mrblue · February 4, 2012, 4:30am

Hi,

i decided to set up a dedicated server just for elasticsearch (debian
6.0 squeeze 64 lamp). ES works fine so far, but i can´t connect to it
from another server.

Here is a very simple example:

$ch = curl_init();
//curl_setopt($ch, CURLOPT_URL, "http://localhost:9200/alle_uhren/
_search?pretty=true");

curl_setopt($ch, CURLOPT_URL, "http://xxx.x.xxx.xxx:9200/xxxx/_search?
pretty=true");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);

$data = '{
"query" : {
"match_all" : { }
},"size" : "2000"
}';

curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$jason_output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);

print_r($jason_output);

It works fine with localhost, but not from a different server. I can
ping from one server to the other.
Here is what netstat says, there seems to be somthing on 9200, but i
know nothing about these kind of things

tcp 0 0 127.0.0.1:3306 0.0.0.0:*

Any help is apreciated !

You should check iptables rules:

$ iptables -L

And print it here. Probably 9200 port is blocked. As an example in CentOS
all ports, except 22 are blocked for external access.

Hello.

You may also check if localhost resolve to the local ipv6 address, or try -Djava.net.preferIPv4Stack=true on the java startup command line. Or disable ipv6 on your box if you don't use it.

Rgds.

The problem is that it's only listening on port 9200 for IPv6, not
IPv4:

LISTEN tcp6 0 0 :::9200 :::*

This should help:
