You can discover the power of the nodl through the use of graphical user interfaces (GUI) such as RTL (Ride the Lightning), software wallets such as Zap or Joule or payment processing applications such as BTCPay. However, should you wish to go even further, you may want to access the command line interface [cli] for either bitcoind or lnd.
Open your command line interface and type
ssh email@example.com or
ssh root@<insert your IP>
and confirm with your ssh password.
In order to manage bitcoind and lnd, execute as root user:
root@nodl:~# su - bitcoin
Now you can use both
bitcoin@nodl:~$ bitcoin-cli and
bitcoin@nodl:~$ lncli commands, find a complete list of possible commands by executing
bitcoin@nodl:~$ bitcoin-cli hel and
bitcoin@nodl:~$ lncli help
