  2. What is TightVNC? • Open source remote desktop solution • Uses Virtual Network Computing’s (VNC) RFB protocol (remote framebuffer) • Consists of Client and Server application • Client uses port 5900 • Server listens on port 5800 • Ports are user configurable

  3. X11vnc • VNC Server program • Command-line driven • Installed in Ubuntu with the following command: • apt-get install x11vnc vnc-java • Optionally can configure configuration files but can use command line to run sessions

  4. X11vnc Sample Command Line Options • To set x11vnc to allow access each time, include the -nopw -accept popup:0 options • To set x11vnc to only listen for the next connection, include the -once option • To set x11vnc to continually listen for connections, include the -forever option • To set a password, include the -usepw option • To put x11vnc in view-only mode, include the -viewonly option • To set x11vnc to only allow local connections, include the -localhost option

  5. X11vnc Auto Start • Start on Boot script located in /etc/init/x11vnc.conf start on login-session-start script x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -forever -bg -o /var/log/x11vnc.log -rfbauth /etc/x11vnc.pass end script

  6. Install TightVNC • Cross Platform • Simple Installation – also runs standalone • All you need is to know the destination server address and have access

  7. Pros • Why use VNC software? • Allows users to have remote access to many operating systems with GUI • Open Source for personal and enterprise • Easy to use • Performs well for how light weight it is

  8. Cons • Not very secure • Password is encrypted but nothing else. • Not recommended for use over the internet • Encryption key usage is in the works for future versions • Can be buggy • Server side command line configuration can have a learning curve – no GUI

  9. Demonstration
