VNC

Enable SSH Port Local Forwarding

  • VNC is very insecure because the traffic is sent over an insecure connection
    • Unencrypted connection that can be sniffed
  • SSH Port Local Forwarding creates an encrypted session over port 22 
# Enable TCP forwarding
nano /etc/ssh/sshd_config

############ START OF FILE ############
AllowTcpForwarding yes
############ END OF FILE ############

# Restart SSH
systemctl restart sshd

# Check status
systemctl status sshd

Install

  • This startup script will enable a VNC server that listens on localhost for SSH Port Local Forwarding
  • The password will be used to login through VNC 
# Install tight vnc server
apt-get install -y tightvncserver

# Create start up script
nano /etc/init.d/tightvncserver
