Goal

I would like to use VNC to access a Ubuntu 18.04 system from windows like I do with the Raspberry Pi.

  • Connect to the existing desktop
  • Keep the connection secure

This has been a bit of a struggle for a number of gotchas.

Overview

As I understand it ( may not have figured it out all the way )

  • VNC has a server ( run on the machine you wish to view ) and viewer ( run on the machine you wish to access).
  • In addition to having several components there are many versions of VNC. Directions for each differ, and differ across versions of Linux.
  • I will focus on Tiger VNC and Ubuntu 18.04
  • To get VNC working there seem to be various components.
    • VNC server
    • Desktop software ( there are many different ones, you may need to install -- however here I want to run on the default Ubuntu 18.04 desktop so no install is necessary )
    • A way to connect to the VNC server -- many servers will only connect to localhost 127.0.0.1 so we will use vnc tunnelling to make a remote connection appear to be on localhost


Other Software Used

before installs

  • sudo apt update
  • sudo apt upgrade


Process viewer (htop)

  • Why This will let you see what vnc software is running.
  • Install >> sudo apt -install htop
  • Run >> htop
  • Exit >> ctrl-c

IfConfig

  • Why see your server's tcp ip address
  • Install >> sudo apt -install ??
  • Run >> ifconfig
  • Exit >> just ends

SSH

  • Install >> sudo apt install openssh-server

what

might this help gconf-editor

Ubuntu text editor ( gedit )

  • Install >> apt-get -install  ??
  • Run >> htop

Ubuntu File Browser

Tiger VNC

  • Note: there may already be vncserver software installed perhaps vineo ??
  • Install >> sudo apt-get install tigervnc-scraping-server
  • Install ( may not be needed ) >> sudo apt install tigervnc-standalone-server tigervnc-viewer
  • Set password >>vncpasswd << gotcha, if run server with no password set. If this does not run find an install -- perhaps full tiger vnc to get it.
  • Run gotcha >> x0tigervncserver << but gotcha, needs to be pointed to password file so
  • Run >> x0tigervncserver -PasswordFile ~/.vnc/passwd
  • Run gotcha this is not the scraping server may not be installed >> tigervncserver -xstartup /usr/bin/xterm
  • Set password >>vncpasswd << gotcha, if run server with no password set it will not work.
  • edit configuration file >> use file browser but .vnc is hidden so turn on hidden file abillity ( one of its menus )
    • sudo apt-get install git psmisc
  • set password with >> vncpasswd
  • see running servers >> vncserver -list
  • what runs with command vncserver >> which vncserver
    right answer is ?? 

/usr/bin/vncserver

How to start a vnc server for the actual display (scraping) with TigerVNC https://www.howtoforge.com/tutorial/how-to-start-a-vnc-server-for-the-actual-display-scraping-with-tigervnc/


Webmin

  • rather than use the desktop use a web based admin tool:


  • Install >> sudo apt-get install webmin << seems to work on virtual machine but not real one ??
  • Start >> sudo /etc/webmin/start
