| − | * Full VNC desktop ( there are other remote desktops )
| |
| − | * Why not just use option Share Desktop ? Because mine would not turn on thats why. Why it would not turn on, I was not able to figure out.
| |
| − | | |
| − | Of these VNC is the most difficult, and the one I wanted, it will be discussed first. It also mentions tools that may be useful in other approaches.

| − | === VNC full Desktop -- My 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
| |
| − | * Stick to open source.
| |
| − | | |
| − | 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. Make sure you directions match your software.
| |
| − | * 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, of course, it is already installed. )
| |
| − | ** 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
| |
| − | | |
| − | | |
| − | === 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
| |
| − | | |
| − | ==== System Control ====
| |
| − | | |
| − | systemctl vs. service
| |
| − | | |
| − | * sudo systemctl stop httpd << The Apache server would stop and you'd be returned to the bash prompt. To start the same service, we'd issue the command:
| |
| − | | |
| − | * sudo systemctl start httpd << The service would start and you'd be returned to your bash prompt.
| |
| − | | |
| − | | |
| − | * sudo systemctl restart httpd << to restart the same service
| |
| − | | |
| − | ==== 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

| |
| − | | |
| − | * set password with >> vncpasswd
| |
| − | * see running servers >> vncserver -list | |
| − | * what runs with command vncserver >> which vncserver
| |
| − | right answer is ??
| |
| − | /usr/bin/vncserver
| |

| − | ==== Workflow In Use ====
| |
| − | | |
| − | * Boot the Ubuntu machine, if powered off just power on, if you have access sudo reboot ?? or restart will boot it.
| |
| − | * Wait
| |
| − | * On the windows machine connect with Putty and log in with your password and id
| |
| − | * In Putty issue the command to start the VNC Server >> ./startvnc start
| |
| − | * Start the windows VNC viewer the one I used is VNC viewer from RealVNC ... because this is the one I use for the Rasberry Pi ( you need to have a configuration with the right ip address of the Ubuntu Machine the same as the one in Putty
| |
| − | | |
| − | === Easiest, no Desktop Putty SSH ===
| |
| − | | |
| − | * Install ssh on Ubuntu
| |
| − | | |
| − | * Run Putty on windows using the IP address of the Ubuntu machine
| |
| − | | |
| − | | |
| − | .
| |
| − | | |
| − | === Webmin Somewhat Graphical, Easier than Command Line === | |
| − | | |
| − | * 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 << you can do this thru putty, then open your browser
| |
| − | * Stop >> /etc/webmin/stop << not tested may need sudo
| |
| − | * Restart >>/etc/init.d/webmin restart
| |
| − | | |
| − | * access on your browser >>https://192.168.0.95:10000/ not work:?? http://192.168.0.95:10000/
