+- connection_type - rpc
+- manage_daemon - false
+- manage_wallet_daemon - true
+- rpchost - ip of remote monero node (192.168.1.9)
+- rpcport - rpcport that monero is listening on remote node (18081)
+- rpcuser - test_user

+    data-dir=PATH_TO_MONERO_DATADIR
+    restricted-rpc=1

+    rpc-bind-port=18081
+    rpc-bind-ip=192.168.1.9
+    prune-blockchain=1
+
+Start the remote monerod binary with `--confirm-external-bind`
+
+Remember to open port 18081 in the remote machine's firewall if necessary.
+
+You can debug the connection using curl (from the local node)
+
+    curl http://192.168.1.9:18081/json_rpc -u test_user:test_pwd --digest -d '{"jsonrpc":"2.0","id":"0","method":"get_info"}' -H 'Content-Type: application/json'
