   *>url  https://askubuntu.com/questions/4474/enable-remote-vnc-from-the-commandline

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 :

<?xml version="1.0"?> <gconf>

   <entry name="vnc_password" mtime="1289267042" type="string">

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 )

starting thru ssh with putty does not work ( get an authentication error, but can start locally )
to start thru ssh install startup script as on https://www.howtoforge.com/tutorial/how-to-start-a-vnc-server-for-the-actual-display-scraping-with-tigervnc/ this script can be run thru putty

- sudo apt-get install git psmisc

- git clone https://github.com/sebestyenistvan/runvncserver
- cp ~/runvncserver/startvnc ~
- chmod +x ~/startvnc
- ./startvnc start

Manual Page: may not be the best >> https://man.cx/x0tigervncserver(1)

set password with >> vncpasswd
see running servers >> vncserver -list
what runs with command vncserver >> which vncserver

    right answer is ??

/usr/bin/vncserver

what about owner of the .Xauthority file, https://askubuntu.com/questions/772090/how-can-i-resolve-x11-problem-with-putty-if-i-have-this-error-putty-x11-proxy

Webmin

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

Website Webmin http://www.webmin.com/

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

access on your browser >>https://192.168.0.95:10000/ not work:?? http://192.168.0.95:10000/

How To Install Webmin on Ubuntu 18.04 | DigitalOcean https://www.digitalocean.com/community/tutorials/how-to-install-webmin-on-ubuntu-18-04 sudo nano /etc/apt/sources.list sudo gedit /etc/apt/sources.list

tiger vnc

sudo apt install tigervnc-standalone-server tigervnc-viewer

start in terminal with

vncserver

vncviewer

russ@UbuntuBase-VB:~$ vncserver

New 'UbuntuBase-VB:1 (russ)' desktop at :1 on machine UbuntuBase-VB

Starting applications specified in /etc/X11/Xvnc-session Log file is /home/russ/.vnc/UbuntuBase-VB:1.log

Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/russ/.vnc/passwd :1 to connect to the VNC server.

russ@UbuntuBase-VB:~$ vncserver

loopback IP address is 127.0.0.1

not done yet ------

Start TigerVNC vncserver at boot

The ubuntu install package also registers a system service, making it easy to define listening vnc servers on startup. Edit the file /etc/default/vncserver and add the display number and user to start as:

sudo gedit /etc/default/vncserver

VNCSERVERS="1:myusername"

Then enable the service at boot with:

sudo update-rc.d vncserver defaults

end not done

vncserver in terminal to start

Use xtigervncviewer -SecurityTypes VncAuth -passwd /home/russ/.vnc/passwd :1 to connect to the VNC server.
