RE: HOWTO create a witness_node on a fresh (rented) Debian 8 linux box

[jhonione]

generally understood, but in addition to your commands are added

update your system and install ntp

sudo apt-get update && sudo apt-get -y upgrade
sudo apt-get install ntp
sudo dpkg-reconfigure tzdata # to set your time zone

Install the build tools

sudo apt-get install gcc g++ cmake make libbz2-dev libdb++-dev libdb-dev libssl-dev openssl libreadline-dev autoconf libtool git libncurses-dev build-essential kernel-package libncurses-dev doxygen libboost-all-dev autotools-dev automake

you may have to run this on a fresh install and reboot

sudo dpkg --configure -a
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
sudo reboot

but still from time to get the message
Floating point exception (core dumped)
and the synchronization process stops
