Issues with connecting Couchbase to ElasticSearch with XDCR


I have been trying for some time now to get the cluster connection working. To start with, here is the versions and topology:

Two couchbase servers running version: 4.1.0-5005 Community Edition (build-5005)
Connecting to a (for the moment) single node ElasticSearch version: 2.3.1

To connect we have installed the correct “elasticsearch-transport-couchbase” version:

Config snip from /etc/elasticsearch/elasticsearch.yml bo elastic3 [site, local]
couchbase.username: Administrator
couchbase.password: ********
couchbase.maxConcurrentRequests: 1024
max_clause_count: 5120

What I have tried so far:

  • Reinstall plugin
  • Trying different settings, like below: eth0:ipv4 site
  • Restarted couchbase cluster
  • Restarted elasticsearch server

When issuing the command: netstat -ano | grep LISTEN
tcp6 0 0 :::* LISTEN off (0.00/0/0)

Doing the same on another working setup, but earlier version:

tcp6 0 0 :::* LISTEN off (0.00/0/0)

Cant seem to get it to listen to the correct adress:

CURL command on localhost from elasticsearch also works:
curl -u Administrator:******** -X GET http://

But not from couchbase servers or any other server. How can I resolve this?

Thank you
