If you want you can save it for easier later use by adding a name in Saved Sessions and clicking Save. I installed the server version of Ubuntu, so to be able to have a desk top when I log into vnc I need to install a few things in Ubuntu. First off we need to install the Gnome components for our virtual desktop.
Type or copy and paste:. To keep the desktop and login window from opening in Ubuntu everytime it starts we want to mask out the few lines which start the service. Now the desktop and login won't start in Ubuntu. NOTE: This only installs a basic desktop, if you want to be able to use programs from your virtual desktop, network manager, media players, office, etc, they will need to be installed after vnc server is installed.
B: We need to install VNC server to be able to interact with the gnome components for the desktop. When prompted type Y and press Enter. This will install VNC Server which is required for running a virtual desktop on another machine. We now need to kill the session we just created and make change the startup script for VNCServer to make it work properly. This should save the changes and bring you back to the command line. If you make a mistake editing the file then issue :q!
When you launch it type your hda server name followed by a colon and the number 1 this is the name you gave it when you installed Ubuntu for example: Ubuntu A script is basically a file containing a list of commands which will be executed each time you run it. I put all my scripts in a directory below my "home" folder in a folder called scripts.
Next we need to make the file executable so, assuming you called your script StartVNC. Now open your browser and go to your HDA and click on the webmin app you already installed, click continue to this website at the cert warning. Then click the Create a new scheduled cron job option at the top of the screen that opens. Click the button next to the Execute cron job as and choose the username you created when you installed Ubuntu. In the When to Execute - Simple schedule drop-down list choose When system boots then click the Create button at the bottom of the screen.
First test that you've set the job up correctly within Webmin. To set x11vnc to continually listen for connections, include the -forever option. To put x11vnc in view-only mode, include the -viewonly option. To set x11vnc to only allow local connections, include the -localhost option. Xauth -display :0 options to be specified on the command-line. The argument value for the -auth option may be found previously with x11vnc -findauth. Xauth -display :0 If you find a blank screen, check the x11vnc FAQ entry on headless servers.
Because it's highly integrated with KDE, running it in other environments is difficult. To set krfb to request access each time, tick Confirm uninvited connections before accepting To set a password, type a hard-to-guess password into the Password input box. To put krfb in view-only mode, untick Allow uninvited connections to control the desktop.
There's no built-in way to only allow local connections, although see below for a solution. Once mode Krfb doesn't have a built-in way to accept the next connection then stop listening for connection attempts. However, the following Python script will listen for a single connection then exit krfb:! Make sure that the initial ' ' character is the very first character in the file, save the file as krfb. Although this simple program won't open a window of any kind, it will quietly wait for the next VNC client to connect to your computer, then pass the connection through to krfb.
This script will only listen for local connections. To allow connections from anywhere, change Invitations Krfb lets you create "invitations", or individual passwords that are deactivated after an hour or after one use. These are a handy way of giving people one-time access to a computer, but only provide limited security.
For example, if you send someone an invitation by e-mail or instant messaging, an attacker could read your invitation message as it went over the Internet and use it to log in. Invitations can be useful when you want to let other people view your desktop, but you still need to follow the normal precautions when letting other people view your desktop.
This makes it much less useful for some things like remote help , but much more useful for others like creating a public area for collaboration. Like x11vnc, tightvnc is designed to be run from the command-line. To start it, type: tightvncserver -nolisten :1 This will tell tightvnc to listen for VNC connections on port from anywhere on the Internet. Without the -nolisten tcp option, tightvnc will also listen for a different type of connection X11 instead of VNC , which isn't usually very useful.
Tightvnc's unusual design means that it can't create a remote desktop on the standard VNC port if you have an ordinary desktop running on your computer. There's no way to set tightvncserver to request access each time. There's no way to set tightvncserver only to accept the next connection, although see below for a similar solution.
Tightvncserver always requires a password, and will ask you to specify one the first time it's run. To set tightvncserver to only allow local connections, include the -localhost option. Once mode Tightvncserver can't be set to accept the next connection then stop listening for connection attempts. But it can be set to automatically disconnect each client when the next client connects, and can be stopped after your connection is disconnected.
To only allow local connections and automatically disconnect clients, start tightvnc by typing: tightvncserver -nolisten tcp -localhost -nevershared :1 Then when your client is disconnected by the next client connecting, type: tightvncserver -kill :1 Customising your session By default, tightvncserver provides a session with a simple window manager and a terminal.
