Beaglebone Black - Remote connection (VNC)

Based on this youtube video

Make sure your BBB is connected (USB) and powered on

• Install Tight VNC 
• Download Putty (you only need putty itself)
• In Putty: connect (SSH) to 192.168.7.2 port 22
• Login as 'root', no password
• Install & start VNC server (still in Putty):
• Type 'opkg install x11vnc'
• Type 'x11vnc -bg -o %HOME/.x11vnc.log.%VNCDISPLAY -auth /var/run/gdm/auth-for-gdm*/database -display :0'
• Connect to 192.168.7.2 in your VNC client.

To enable VNC from the moment you plug in your BBB, put the last command in a shell script (name.sh) and add that file to System > Preferences > Startup Applications

You might encounter an error connecting in Putty, mentioning the server closed unexpectedly. Try running this code in cloud9 directly to your BBB:

var fs = require('fs');

var destroyed_key_file = '/etc/dropbear/dropbear_rsa_host_key';

fs.readFile(destroyed_key_file, function (err, data) {

  if (err) throw err;

  

  if( data===null || data.length===0 )

  {

    console.log("we have a corrupted host key file... try do delete it");

    fs.unlink(destroyed_key_file, function (err) {

    if (err) throw err;

        console.log('successfully deleted ' + destroyed_key_file);

        console.log('you should now reboot your beaglebone.');

        console.log('the /etc/init.d/dropbear script will create a new rsa host key file for you.');

        console.log('after the reboot you should be able to login over ssh');

    });

  } else {

      console.log("it seems that you have another problem, sorry");

  }

});
