🛠 Bitcoin-Standup Linux Scripts

by Peter Denton and Christopher Allen

This script installs the latest stable version of Tor, Bitcoin Core, Uncomplicated Firewall (UFW), Debian updates, enables automatic updates for Debian for good security practices, installs a random number generator, and optionally a QR encoder and an image displayer.

Additional Information

For more information on Bitcoin-Standup:

1. The Main Bitcoin-Standup Repo contains general information on the project.
2. Why Run a Full Node? details why you would want to run a full node in the first place.
3. Security for Bitcoin-Standup offers notes on ensuring the security of your Bitcoin-Standup node.

Status — Work-in-Progress

Bitcoin-Standup is an early Work-In-Progress, so that we can prototype, discover additional requirements, and get feedback from the broader Bitcoin-Core Developer Community. It has not yet been peer-reviewed or audited. It is not yet ready for production uses. Use at your own risk.

Installation Instructions

There are two linux based StandUp scripts; StandUp.sh and LinodeStandUp.sh.

• LinodeStandUp.sh is built as a StackScript for the Linode platform and can be used as is. It's been tested on Debian 9 (Stretch) and Debian 10 (Buster).
• StandUp.sh can be used on a Debian VPS and has been tested on Debian 9 (Stretch) and Ubuntu 18.04.

You will use different installation methods depending on which script you use (or if you want to run the installation entirely by hand)

Method One: Install Using Standup.sh

In order to run this script you need to be logged in as root, and enter in the commands listed below. The $ represents a terminal command prompt; do not actually type in a $.

1. Give the root user a password: $ sudo passwd

2. Switch to the root user: $ su - root

3. Create the file for the script: $ nano standup.sh

   • Nano is a text editor that works in a terminal, you need to paste the entire contents of the Standup script into your terminal after running the above command. Then you can type:
     • control x (this starts to exit nano)
   • y (this confirms you want to save the file)
   • return (just press enter to confirm you want to save and exit)

4. Make sure the script is executable: $ chmod +x standup.sh

5. Run the script with the optional arguments like : $ ./standup.sh "<insert Tor V3 pubkey>" "<insert node type>" "<insert ssh key>" "<insert ssh allowed IP's>" "<insert password for standup user>"

   • It is highly recommended to add a Tor V3 pubkey for cookie authentication, so that even if your QR code is compromised an attacker would not be able to access your node.
   • The node type is "Mainnet", "Pruned Mainnet", "Testnet", "Pruned Testnet", or "Private Regtest", default is "Pruned Testnet".
   • If you supply a SSH_KEY in the arguments, you will be able to easily access your node via SSH using your rsa pubkey.
   • If you add SYS_SSH_IP, you host willl only accept SSH connections from those IPs.
   • The password is used for a user called standup.

Method Two: Install Using LinodeStandup.sh

The LinodeStandup.sh script is intended for use at Linode.com. You can find more precise information on using it from our Learning Bitcoin from the Command Line course. The following is a summary.

First, copy the LinodeStandup.sh script to your Linode:

1. Copy the complete LinodeStandup.sh script.
2. Go to the Stackscripts page on your Linode account; choose Create New Stackscript
3. Paste LinodeStandup.sh into the "Script" area. Make sure you got it all, from the "#!/bin/bash" to the "exit 1"!
4. Choose "Debian 10" (Buster) for the "Target Images".
5. Click "Save".

Second, create a node based on the script:

6. On the Stackscripts page, click on the "..." to the right of your new script and choose "Deploy New Linode".
7. Fill in a hostname and the password for the "standup" user.
8. Choose an Installation Type in your options. This is likely "Mainnet" or "Pruned Mainnet" if you are setting up a node for usage and "Pruned Testnet" if you're just playing around.
9. Fill in any other advanced options.
10. Choose a region for where the Linode will be located.
11. Choose a Linnode plan. Our general experience is that a Linode 8GB is needed to store the whole blockchain if you choose unpruned "Mainnet", while for testnet and the pruned options (and regtest) you'll instead be dependent on memory, where a Linode 4GB will definitely be sufficient, and a Linode 2GB has worked or not on various versions of Bitcoin Core. (If it fails, you'll get out-of-memory errors.)
12. Enter a root password.
13. Click "Create".

Method Three: Install by Hand (Not Recommended)

Finally, if you prefer, you can install all of the packages for Bitcoin-Standup by hand. The Learning Bitcoin from the Command Line course has instructions on how to do so, but those methodologies will only install a full node, not include tor and not linking with the Quick Connect API. As such, this methodology is not recommended, but is simply included to provide you with the widest breadth of options.

Because this by-hand methodology does not embody the full Bitcoin-Standup protocol, the following notes on what to do next do not apply.

After Installation

By default the scripts set up a pruned testnet node and a Tor V3 hidden service controlling your rpcport and enable the firewall to only allow incoming connections for SSH. Tor and Bitcoin Core are set up as systemd services so that they start automatically after crashes or reboots.

1. You should check the Bitcoin-Standup logs to ensure that the installation went correctly: $ cat /standup.err $ cat /standup.log

2. You can now scan a QR code from Bitcoin-Standup to link to a remote app such as FullyNoded 2. There are two ways to do so.

   • A btcstandup:// uri appears in plain text in the /standup.log. You can convert that to a QR Code.
   • Alternatively, you can directly access /qrcode.png, which you can open and scan. One way to do so is to sudo apt-get install fim then fim -a qrcode.png to display the QR in a terminal (as root).

3. After reviewing your logs and accessing your QR code, you should remove the /btcstandup.uri, /qrcode.png, /standup.log, and /standup.err files.

rm -R -f standup.log
rm -R -f standup.err
rm -R -f btcstandup.uri
rm -R -f qrcode.png
