Xen / XCP-ng : Forward VM console session to local port for VNC access.

XCP-ng Easy VNC to VM Console

For people that are tired of manually looking up DOM ID, executing socat and establishing their SSH tunnel.

  • Edit connect_vm.sh to add the IP address of your XCP-ng host.
  • Ensure socat is installed on the host. If it isn't, use yum install socat
  • For best results, set up keys for SSH root login to our XCP-ng host.
  • Place the script forward_console.sh on the XCP-ng host, in /root.
  • Place the script connect_vm.sh locally on the computer you will VNC from.
  • Optionally, you may edit connect_vm.sh to launch your preferred VNC viewer.

Get the directory of a subclass from the parent class in NodeJS.
const path = require('path');
// this is the key function where all the magic happens
function getSubclassDir() {
// override prepareStackTrace
// error.stack will be <CallSite>[] rather than <string>
const original = Error.prepareStackTrace;
Error.prepareStackTrace = function(err, stack) { return stack; };
// create a new error and use the stack

Create a canonical JSON string - ideal for cyptographic signing and verifying.

// get keys and sort them
for(var k in obj) keys.push(k);
keys.sort();
// append each kvp to string
return '{' + keys.reduce(function(prev, cur, i) {
return prev + (i>0?',':'') + '"' + cur + '":' + getCanonicalJSON(obj[cur]);
