SSH into a Vagrant VM, such that Node.js can be debugged from a debugger or IDE in the host operating system. For some reason, port forwarding in the Vagrant file does not work. See https://groups.google.com/forum/#!topic/vagrant-up/RzPooJ0dp6Q

Thanks, this helped me a lot.

Please note that this script is used on the host, when connecting to the guest. In my case, when connecting from a Windows environment, this can be achieved by configuring a SSH tunnel in Putty.

Try this:

Vagrantfile:

config.vm.network :forwarded_port, host: 5858, guest: 5858
config.vm.network :forwarded_port, host: 8080, guest: 8080

SSH to Vagrant

$ vagrant ssh
$ cd /vagrant/....
$ node-inspector &
$ node --debug app.js

Access using:

http://127.0.0.1:8080/?ws=127.0.0.1:8080&port=5858

Works Fine!!

I update this to take an argument as an arbitrary port, https://gist.github.com/drewsonne/747b1ce77cc2f912af0f

By default node-debug will bind to 127.0.0.1 which is loopback.

Use node-debug --web-host=0.0.0.0 to bind it to all interfaces. Forwarding port 8080 should now work.
