Just running

/usr/lib/vino/vino-server should do the job.

Once you have access to your server, I would recommend that you add it to Autostarted Apps so it is always started.

You'll probably like change some settings with :

vino-preferences be very careful when you run vino-preference on a remote machine, if you uncheck "Allow other users to control your desktop", you won't be able to check it back.

or to edit :

~/.gconf/desktop/gnome/remote_access/%gconf.xml Here a sample file :

    VNC SSH


    misc vnc notes

    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
