VPS and Hot wallet Setup

These instructions are intended for those that are setting up a MasterNode Hot wallet on a Linux VPS. This wallet and server will run 24/7 and will provide services to the network via TCP port 9050 for which it will be rewarded with coins. It will run with an empty wallet balance, reducing the risk of losing the funds in the event of an attack.

Order and setup a Linux VPS

  1. Identify a VPS provider and order a Linux Ubuntu 16.04 server. It’s important not to run the VPS at home because of the risk of network instability that could cause loss of connectivity to the server. A VPS that meets the following requirements should cost around $5 per month.

    Recommended VPS Providers:

    VPS Minimum Requirements:

    • Linux - Ubuntu 16.04 - 64 Bit OS
    • 1GB of RAM
    • 20GB of disk space
    • Dedicated Public IP Address
  1. Login to the VPS provider website and configure the external firewall to allow SSH port 22 and the Rupaya Wallet TCP port 9050.
  1. Login to the VPS, via SSH, as the root user.

    • If you need assistance using SSH then please refer to the VPS: Getting Started with an SSH client and SSH Keys section of the guide for more information on how to use SSH to connect to the Linux VPS.
    • If you are running a VPS from Digital Ocean, Vultr, or a similar provider, then you need to use an SSH client, such as Putty, if you want to have copy and paste functionality. Otherwise you will have to type all of the following commands out manually!
  1. Install Linux updates. Run the following commands one at a time:

    apt install make
    apt install aptitude -y
    apt-get update -y
    apt-get upgrade -y
  • NOTE: If a pop up window appears asking “What would you like to do about menu.list?” then select the option: keep the local version currently installed
  1. 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
  1. Install tzdata. Run the following command to install the application that will allow you to select your clock timezone:

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

    dpkg-reconfigure tzdata
  1. 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
  1. Configure the VPS internal firewall to allow SSH port 22 and the Rupaya Wallet port 9050:

    ufw default deny incoming
    ufw default allow outgoing
    ufw allow 22/tcp
    ufw limit 22/tcp
    ufw allow 9050/tcp
    ufw logging on
    ufw --force enable

Create a New User and Login as rupxmn

OPTIONAL STEP: The following steps (1 - 3) are optional. These steps are strongly recommended for those that want to implement security best practices. These steps are recommended so that the Hot wallet is not installed under the root user account.

  • In these steps you will create a new user named rupxmn, set a password, grant that user root access, and login as the new user.
  • All advanced Rupaya setup guides will assume that you used rupxmn as your user.
  • For those of you that want to continue to use root as your user instead of rupxmn, you can skip ahead to the next section Download and Configure the Rupaya Hot Wallet.
  1. Create a new user named rupxmn and assign a password to the new user:

    useradd -m -s /bin/bash rupxmn
    passwd rupxmn
  • Type in a new password, as you are prompted, two times. Be sure to save this password somewhere safe, as you will need it to manage the MasterNode Hot wallet.
  1. Grant root access to the new user rupxmn:

    usermod -aG sudo rupxmn
  1. Login as the new user rupxmn:

    login rupxmn

Download and Configure the Rupaya Hot wallet

  1. Install the Rupaya Hot wallet on the VPS. Download and unpack the Rupaya wallet binaries by running the following commands one at a time:

    wget https://github.com/rupaya-project/rupx/releases/download/v5.0.25/rupayaqt-linux-64bit.tar.gz
    sudo tar xvzf rupayaqt-linux-64bit.tar.gz -C /usr/local/bin/
  1. Start the Hot wallet service. When the service starts, it will create the initial data directory ~/.rupayacore/:

    rupayad -daemon
  1. Generate the MasterNode private key (aka GenKey). Wait a few seconds after starting the wallet service and then run this command to generate the masternode private key:

    rupaya-cli masternode genkey
  1. Copy and save the MasterNode private key (GenKey) from the previous command to be used later in the process. The value returned should look similar to the below example:

    • 87LBTcfgkepEddWNFrJcut76rFp9wQG6rgbqPhqHWGvy13A9hJK
  1. Stop the Hot wallet with the rupaya-cli stop command:

    rupaya-cli stop
  1. Copy the rupaya.conf template, paste it into a text editor, and update the variables manually. All variables that need to be updated manually are identified with the <> symbols around them:

  • Update the variable after rpcpassword= with a 40 character RPC rpcpassword.
  • You will need to generate the rpcpassword yourself.
  • Use the ifconfig command, on the Linux VPS, to find out your Linux VPS IP address. It is normally the address listed after the eth0 interface after the word inet addr:
  • Save your Linux VPS IP address as we are going to use this IP again in the Cold wallet setup
  • Update the variable after externalip= with your Linux VPS IP. Ensure that there are no spaces between the IP address and the port :9050
  • Update the variable after masternodeaddr= with your Linux VPS IP
  • Update the variable after bind= with your Linux VPS IP
  • Update the variable after masternodeprivkey= with your MasterNode private key (GenKey)
  • Once all of the fields have been updated in the text editor, copy the template into your clipboard to be used in the next steps.
  1. Edit the MasterNode Hot wallet configuration file ~/.rupayacore/rupaya.conf:

    nano ~/.rupayacore/rupaya.conf
  1. Paste the updated template into the rupaya.conf configuration file on the Linux VPS.
  • You can right click in Putty to paste the template into the configuration file.

  • This is a real example of what the configuration file should look like when you are done updating the variables.

  • The rpcpassword, IP address ( in this example), and masternodeprivkey will all be different for you:

  1. Save and exit the file by typing CTRL+X and hit Y + ENTER to save your changes.
  1. Restart the Hot wallet with the rupayad -daemon command:

    rupayad -daemon

Verify the Hot wallet is synchronizing with the blockchain

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

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

    rupaya-cli getblockcount
  • NOTE: If your block count is NOT increasing then you will need to stop the Hot wallet with the rupaya-cli stop command and then reindex with the rupayad -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 9050 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.
