Setup VNC and RDP on Ubuntu 16.04

Posted on by

If you need to setup VNC and/or RDP on your Ubuntu system, you can do it.

Original instructions came from hiroom2.com, but I modified these instructions to work for my setup:

https://www.hiroom2.com/2016/05/24/ubuntu-16-04-remote-connect-to-gnome-classic-desktop-with-vnc-xrdp/#sec-5

Download the libraries you need:

sudo apt remove -y vnc4server tightvncserver
sudo apt install -y git and devscripts
sudo apt install -y gnome-panel metacity

You will need to download and compile from source:
(yes, you need these double folders)

cd ~/source
mkdir tigervnc
cd tigervnc
git clone https://github.com/TigerVNC/tigervnc
cd tigervnc

This seems to be the specific build that was working:

git checkout 044e2b87da7121ef6cbd59e88b101d7d8e282896 \
-b 044e2b87da7121ef6cbd59e88b101d7d8e282896

Now we do the build:

ln -s contrib/packages/deb/ubuntu-xenial/debian

sudo apt install -y $(grep Build-Depends: debian/control | \
sed -e 's/Build-Depends://g' -e 's/([^\)]*)//g' -e 's/,//g')

chmod a+x debian/rules
fakeroot debian/rules binary

Now install the deb packages:

cd ..
sudo dpkg -i *.deb || (sudo apt -f install -y; sudo dpkg -i *.deb)
cd ..

Install GNOME:

sudo DEBIAN_FRONTEND="noninteractive" apt install -y gnome

echo "gnome-session-classic" > ~/.xsession

mv ~/.vnc/xstartup ~/.vnc/xstartub.bak

vncpasswd

RDP Installation:

sudo apt install -y xrdp
sudo systemctl enable xrdp

If you are running this in a VirtualBox, you will need to do some port forwarding:

Default VNC port: 5901
VirtualBox port: 15901 (or whatever)

Default RDP port: 3389
VirtualBox port: 13389 (or whatever)

Build Zencash (ZEN) wallet on Ubuntu

Build Zencash (ZEN) wallet on Ubuntu:

Build everything:

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

The actual build takes a long time:

mkdir ~/source
cd ~/source
git clone https://github.com/ZencashOfficial/zen.git
cd ~/source/zen/zcutil
./build.sh
./fetch-params.sh

Run wallet and then stop it:

cd ~/source/zen/src
./zend -daemon
./zen-cli stop

You will now see a folder ~/.zen
Create zen.conf in this folder that looks like this:

rpcuser=YourUserName
rpcpassword=YourPassword
rpcport=8236
gen=1

Now start the server again:

cd ~/source/zen/src
./zend -daemon

Use the cli (command line interface) to getinfo:

./zen-cli getinfo

ZEN update (when you need to upgrade)

cd ~/source/zen
git pull
cd ~/source/zen/zcutil
./build.sh
./fetch-params.sh
