Installing Hush

Install

sudo echo 'deb https://dl.bintray.com/myhush/hush/ hush main' >> /etc/apt/sources.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 379CE192D401AB61 
sudo apt-get update
sudo apt-get install hush

Create a HUSH configuration file (important):

mkdir -p ~/.hush
echo "rpcuser=username" >> ~/.hush/hush.conf
echo "rpcpassword=`head -c 32 /dev/urandom | base64`" >>~/.hush/hush.conf
echo "addnode=myhush.network" >> ~/.hush/hush.conf
echo "addnode=us.madmining.club" >> ~/.hush/hush.conf
echo "addnode=zdash.suprnova.cc" >> ~/.hush/hush.conf

Building Hush from source

Building Hush from source will take some time but your efforts will be rewarded :)

Requirements

You will need at least 2GB of RAM to build hush from git source, OR you can enable a swap file. To enable a 4GB swap file on modern Linux distributions:

sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

You will need to have Git and a C++ compiler and libtool and a a few other libraries, depending on your setup.

Building

The following build process generally applies to Ubuntu (and similar) Linux distributions. For best results it is recommended to use Ubuntu Linux 16.04 or later. Build HUSH along with most dependencies from source by running Get dependencies:

sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python \
      zlib1g-dev wget bsdmainutils automake

Create a HUSH configuration file (important):

mkdir -p ~/.hush
echo "rpcuser=username" >> ~/.hush/hush.conf
echo "rpcpassword=`head -c 32 /dev/urandom | base64`" >>~/.hush/hush.conf

Downloading Git source repo, building and running Hush

# pull
git clone https://github.com/MyHush/hush.git
cd hush
# fetch key
./zcutil/fetch-params.sh
# Build
./zcutil/build.sh -j$(nproc)
# Run a HUSH node
./src/hushd

Supported Platforms

Currently only Linux is officially supported. Windows/Mac OS X versions are in the works...

We aim to support all platforms, but there is only so much time in the day.

Currently, any ARMv7 machine will not be able to build this repo, because the underlying tech (zcash and the zksnark library) do not support that instruction set.

This also means that RaspberryPi devices will not work, unless they have a newer ARMv8
