Inside the  config, kingcoin.conf:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
rpcuser = yourUserName
rpcpassword = YourPassword

rpcallowip=127.0.0.1
rpcport = 12350  # listen for RPC connections on this port
port = 12349

daemon=1
server=1 # tells kingcoin.conf to accept JSON-RPC commands
listen=1

addnode=45.33.58.218:32942
addnode=51.15.162.24:12316
addnode=192.3.19.154:12316
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

That should work.
