Updating

Run git pull in the nix-bitcoin directory, enter the nix shell with nix-shell and redeploy with nixops deploy -d bitcoin-node.

  1. Import jonasnick's gpg key

    gpg2 --receive-key 36C71A37C9D988BDE82508D9B1A70E4F8DCD0366
    
  2. Trust jonasnick's gpg key

    gpg2 --edit-key 36C71A37C9D988BDE82508D9B1A70E4F8DCD0366
    trust
    4
    quit
    
  3. Verify commit after git pull

    git verify-commit <hash of latest commit>
    

Nodeinfo

Run nodeinfo to see your onion addresses for the webindex, spark, etc. if they are enabled.

Connect to spark-wallet

  1. Enable spark-wallet in configuration.nix

    Change

    # services.spark-wallet.enable = true;
    

    to

    services.spark-wallet.enable = true;
    
  2. Deploy new configuration.nix

    nixops deploy -d bitcoin-node
    
  3. Get the onion address, access key and QR access code for the spark wallet android app

    journalctl -eu spark-wallet
    

    Note: The qr code might have issues scanning if you have a light terminal theme. Try setting it to dark or highlightning the entire output to invert the colors.

  4. Connect to spark-wallet android app

    Server Settings
    Scan QR
    Done
    

Connect to electrs

  1. Enable electrs in configuration.nix

    Change

    # services.electrs.enable = true;
    

    to

    services.electrs.enable = true;
    
  2. Deploy new configuration.nix

    nixops deploy -d bitcoin-node
    
  3. Get electrs onion address

    nodeinfo | grep 'ELECTRS_ONION'
    
  4. Connect to electrs

    On electrum wallet machine

    electrum --oneserver --server=<ELECTRS_ONION>:50001:t
    

Connect to nix-bitcoin node through ssh Tor Hidden Service

  1. Run nodeinfo on your nix-bitcoin node and note the SSHD_ONION

    nixops ssh operator@bitcoin-node
    nodeinfo | grep 'SSHD_ONION'
    
  2. Create a SSH key

    ssh-keygen -t ed25519 -f ~/.ssh/id_ed25519
    
  3. Place the ed25519 key's fingerprint in the configuration.nix openssh.authorizedKeys.keys field like so

    # FIXME: Add your SSH pubkey
    services.openssh.enable = true;
    users.users.root = {
      openssh.authorizedKeys.keys = [ "[contents of ~/.ssh/id_ed25519.pub]" ];
    };
    
  4. Connect to your nix-bitcoin node's ssh Tor Hidden Service, forwarding a local port to the nix-bitcoin node's ssh server

    ssh -i ~/.ssh/id_ed25519 -L [random port of your choosing]:localhost:22 root@[your SSHD_ONION]
    
  5. Edit your network-nixos.nix to look like this

    {
      bitcoin-node =
        { config, pkgs, ... }:
        { deployment.targetHost = "127.0.0.1";
        deployment.targetPort = [random port of your choosing];
        };
    }
    
  6. Now you can run nixops deploy -d bitcoin-node and it will connect through the ssh tunnel you established in step iv. This also allows you to do more complex ssh setups that nixops ssh doesn't support. An example would be authenticating with Trezor's ssh agent, which provides extra security.
