VPS and Hot wallet Setup

These instructions are intended for advanced users that are setting up a MasterNode Hot wallet on a Linux VPS and don’t want to waste time with all those pesky details and explanations.

Order and setup a Linux VPS

  1. Identify a VPS provider and order a Linux Ubuntu 16.04 server.

    Recommended VPS Providers:

    VPS Requirements

    • Linux - Ubuntu 16.04 - 64 Bit OS
    • 1GB of RAM
    • 20GB of disk space
    • Dedicated Public IP Address
  2. Login to the VPS provider website and configure the external firewall to allow SSH port 22 and the Liberty Wallet TCP port 10417.

  3. Login to the VPS, via SSH, as the root user.

  4. Install Linux updates:

    apt install make
    apt install aptitude -y
    apt-get update -y
    apt-get upgrade -y
  5. Install fail2ban and create modifiable configs for fail2ban and its jail settings. Run these commands one at a time to install basic ssh protection with fail2ban:

    apt-get install fail2ban -y
    cp /etc/fail2ban/fail2ban.conf /etc/fail2ban/fail2ban.local
    cp /etc/fail2ban/jail.conf /etc/fail2ban/jail.local
  6. Install tzdata. Run the following command to install the application that will allow you to select your clock timezone:

    apt install tzdata
  7. Set your time zone. Run the following command to set your preferred time zone:

    dpkg-reconfigure tzdata
  8. Configure a virtual swap space on the VPS to avoid running out of memory:

    fallocate -l 3000M /mnt/3000MB.swap
    dd if=/dev/zero of=/mnt/3000MB.swap bs=1024 count=3072000
    mkswap /mnt/3000MB.swap
    swapon /mnt/3000MB.swap
    chmod 600 /mnt/3000MB.swap
    echo '/mnt/3000MB.swap  none  swap  sw 0  0' >> /etc/fstab
  9. Configure the VPS internal firewall to allow SSH port 22 and the Liberty Wallet port 10417:

    ufw allow 22/tcp
    ufw limit 22/tcp
    ufw allow 10417/tcp
    ufw logging on
    ufw --force enable

Create a New User and Login as xlibmn

  1. Create a new user named xlibmn and assign a password to the new user:

    useradd -m -s /bin/bash xlibmn
    passwd xlibmn
  2. Grant root access to the new user xlibmn:

    usermod -aG sudo xlibmn
  3. Login as the new user xlibmn:

    login xlibmn

Download and Configure the Liberty Hot wallet

  1. Install the Liberty Hot wallet on the VPS:

    wget https://s3.amazonaws.com/liberty-builds/
    sudo tar xvzf linux-x64.tar.gz -C /usr/local/bin/
  2. Start the Hot wallet:

    libertyd -daemon
  3. Generate the MasterNode private key (aka GenKey):

    liberty-cli createmasternodekey
  4. Copy and save the MasterNode private key (GenKey) from the previous command to be used later in the process:

  5. Stop the Hot wallet with the liberty-cli stop command:

    liberty-cli stop
  6. Copy the liberty.conf template, paste it into a text editor, and update the variables manually:

  7. Edit the MasterNode Hot wallet configuration file ~/.liberty/liberty.conf:

    nano ~/.liberty/liberty.conf
  8. Paste the updated template into the liberty.conf configuration file on the Linux VPS.

  9. Save and exit the file by typing CTRL+X and hit Y + ENTER to save your changes.

  10. Restart the Hot wallet with the libertyd -daemon command:

    libertyd -daemon

Verify the Hot wallet is synchronizing with the blockchain

  1. Run the liberty-cli getinfo command to make sure that you see active connections:

    liberty-cli getinfo
  2. Run the liberty-cli getblockcount command every few mins until you see the blocks increasing:

    liberty-cli getblockcount
  • NOTE: If your block count is NOT increasing then you will need to stop the Hot wallet with the liberty-cli stop command and then reindex with the libertyd -reindex command.
  • NOTE: If you did the reindex and you continue to have issues with establishing connections then check that the VPS provider external firewall is setup correctly to allow TCP port 10417 from anywhere. If that is not setup correctly then you will not be able to proceed beyond this step.

If your block count is indeed increasing, then you can proceed to the next step to setup the Cold wallet.
