I am using the repmgr for replication. I had registered the Master node to repmgr successfully. I had successfully cloned the Master node & Started the Standby server. But the Problem is I cannot register the Standby node in repmgr.
I am using the version repmgr 2.0beta1 (PostgreSQL 9.3.2). Os: Ubuntu 14.04 LTS
While registering the Standby node.
$ repmgr -f /etc/repmgr/repmgr.conf --verbose standby register

I think no details about the standby connection in this log. (I am not sure bcoz I dont know)

Please help me in this issue.
Finally I solved that by changing the repmgr.conf file. I have changed the
conninfo='host=localhost user=repmgr_usr dbname=repmgr_db'
with
conninfo='host=192.168.1.205 user=repmgr_usr dbname=repmgr_db'
i.e.. In Config file we have to give the IP address or Name resolved by the cluster.
